The expressive capacity of international punishment: the limits of the national law analogy and the potential of international criminal law.


To date, scant attention has been paid to sentencing in international criminal law (ICL); indeed, in the historic practice of international criminal tribunals, "the sanction imposed often appears to be little more than an afterthought." (1) This is understandable, for ICL as a field remains in its infancy, but unfortunate, for punishment is the distinctive feature of criminal law, and sentencing the vehicle through which it pursues and expresses its objectives, both practical and moral. The absence of an articulated ICL philosophy of or justification for punishment and the dearth of sentencing principles can be ascribed chiefly to two factors: As a theoretical matter, the abhorrent nature of ICL violations and the catastrophic circumstances that serve as the principal catalyst for ICL's development--the rupture, by war, national, religious or ethnic conflict, or otherwise, of basic social norms against brutal violence (2)--invite "intuitive-moralistic answers," making debate about the rationales for punishing serious human rights atrocities seem pejoratively academic; (3) as a practical matter, perhaps in part for that reason, the principal positive law instruments drafted to govern international trials of ICL violations say remarkably little about the purposes of punishment and include comparably laconic sentencing provisions. (4)

Punishment, however, whether authorized by international or national law, (5) requires justification; otherwise, it is simply cruelty. (6) And sentencing practices, international no less than national, should reflect and foster the goals of punishment. Yet in penal theory, as elsewhere, "the mechanical transfer of domestic criminal law principles to the international context ... is fraught with dangers." (7) Justifications for punishment common to national systems of criminal law cannot be transplanted unreflectively to the distinct legal, moral, and institutional context of ICL. (8)

Use of the national law analogy in diverse areas of international legal theory and practice boasts a long pedigree and an equally long and powerful history of criticism. (9) But application of the national law analogy proves particularly problematic for ICL because it strives to combine the paradigms of two very different legal fields: (1) classical international law--a profoundly consensual body of law based on broadly shareable norms among nation-states and occupied mainly with their rights and duties inter se; and (2) national criminal law--a profoundly coercive body of law often understood to embody the most fundamental norms and values of a local community, generally that of a single nation-state (or political subdivision). (10) In particular, ICL differs from national criminal law in at least three significant ways that the national law analogy can obscure.

First, unlike national criminal law, ICL purports to serve multiple communities, including both literal ones--for example, ethnic or national communities--and the figurative "international community," which, needless to say, is not monolithic; it consists of multiple, often competing, constituencies and interests. ICL attempts to mediate between the divergent interests and goals of several bodies of law (national and international) promulgated by these overlapping, but far from identical, constituencies. At sentencing, arrayed against these diverse communal interests and objectives is the convicted's core liberty interest.

Second, the national law analogy can obscure the collective character of ICL crimes (war crimes, crimes against humanity, genocide, and aggression), a feature that distinguishes them from most similar crimes of violence in the national sphere. (11) Arguably, the collective nature of the victim of international crimes--for example, a national, racial, or ethnic group--aggravates the culpability of the perpetrator, just as the prejudicial motive and harm of a bias crime render an assault or murder, for example, more blameworthy because of secondary harms. (12) At the same time, the collective nature of the perpetrator--his role and status relative to the nation-state, military organization, or other collective entity implicated by ICL crimes--arguably mitigates culpability in some circumstances insofar as collectivity might be thought to diffuse moral responsibility, mitigating each perpetrator's guilt in some proportion to that of the collective. (13)

Third, perpetrators of ICL crimes often act in a normative universe that differs dramatically from the relatively stable, well-ordered society that most national criminal justice systems take as their baseline. ICL crimes typically occur during periods of war, ethnic conflict, or other societal breakdown characterized by the erosion, if not inversion, of basic social norms against violence, either generally or relative to certain demonized and dehumanized ethnic, political, religious, national, or racial groups. (14) Conceptualizing war criminals and genocidaires as deviants from fundamental societal norms may make less sense where their criminal conduct, while deviant by reference to international norms and general principles of law common to civilized nations, nonetheless becomes in some sense normative within the criminal's community, be it national, ethnic, racial, or martial. (15)

These observations do not necessarily impugn ICL's coherence or viability as a criminal justice system, but they undoubtedly call for far greater attention to the features that distinguish it. The process of adjudication, however, is an awkward stage at which to recognize and accommodate the salient distinctions. Efforts to modify the ICL trial process itself would be likely to raise questions about fundamental fairness to the defendants and to conflict with due process standards guaranteed by international human rights law. It would be ironic and counterproductive were ICL trials to undermine some international human rights standards in an effort to vindicate others. (16) Sentencing, by contrast, tends to be a far more flexible process; it can more readily be tailored to accommodate the factors relevant to appraising culpability in contexts that often differ dramatically from those presumed by national criminal justice systems. Many issues highlighted by critiques of the national law analogy might thereby be addressed without undermining the integrity and relative uniformity of international due process standards.

This Article offers and defends an expressive account of punishment by international criminal tribunals, which aims to maximize its efficacy while responding to issues of justice, due process, and proportionality raised by a closer examination of the flaws in the analogy between national and international criminal justice. I argue that the expressive dimensions of punishment best capture both the nature of international sentencing and its realistic institutional capacity to make a difference given the legal, political, and resource constraints that will continue, for the foreseeable future, to afflict international criminal tribunals. Expressive accounts of punishment emphasize that incarceration and other forms of "hard treatment" do not impose suffering only, or even primarily, as a means to deter crime or to exact a debt owed by the criminal to society. Rather,
   punishment is a conventional device for the expression of
   attitudes of resentment and indignation, and of judgments of
   disapproval and reprobation, on the part either of the
   punishing authority himself or of those 'in whose name' the
   punishment is inflicted. Punishment, in short, has a symbolic
   significance largely missing from other kinds of penalties. (17)

ICL's ability to contribute to the lofty objectives ascribed to it depends far more on enhancing its value as authoritative expression than on ill-fated efforts to identify the "right" punishment, whatever that could mean, for often unconscionable crimes. (18)

In Part I, while recognizing the force of the critique of the national law analogy, I offer some critiques of that critique and attempt to put it into perspective. I emphasize that ICL must be conceived not as a panacea but as one element of what should be a more comprehensive strategy to prevent and address the circumstances that give rise to serious human rights atrocities. I consider briefly some of the global challenges to ICL. My principal concern, however, is not to appraise ICL's value against other transitional justice mechanisms. With the advent of the International Criminal Court (ICC), the proliferation of hybrid tribunals, and the increasing invocation of universal jurisdiction to try ICL crimes, I assume, at least for the purposes of this Article, that ICL has become a fixture of the international legal landscape that will continue to evolve rapidly. My hope is to clarify more precisely the objectives that ICL might realistically further and to consider how greater attention to punishment--the distinctive feature of any system of criminal law--and its manifestation in the ICL sentencing process might enhance the ability of ICL to contribute to them.

In Part II, I analyze three significant ways in which ICL differs from national criminal justice, focusing on the distinctive nature of the communities, crimes, and perpetrators implicated by ICL generally and international tribunals applying ICL in particular. I argue that, at least for purposes of conceptualizing punishment and sentencing, these tribunals should not, contrary to the prevailing view, be conceived as institutions designed to dispense proxy justice--that is, as substitutes for national criminal justice systems disabled by a lack of political will or resources. I also explore whether and to what extent the collective and psychological pathologies manifest in ICL crimes should bear on their punishment.

In Part III, I briefly trace the transition in ICL penal jurisprudence from a relatively crude retributive impulse, exemplified by the post-World War II trials of the Axis war criminals, to the increasingly complex, but largely haphazard, approach manifest in the judgments of the ad hoc tribunals for the former Yugoslavia and Rwanda. The idea of applying the unwieldy machinery of a newly designed international criminal justice system to the Axis war criminals, which today strikes many as relatively uncontroversial, emerged as an alternative to the proposal, espoused by Winston Churchill and others, that they be summarily executed. In part for that reason, the postwar architects of ICL gave little thought to the propriety or justification of ICL punishment. Until the recent proliferation of ICL, the product of post-Cold War human rights crises in the Balkans, Rwanda, East Timor, and elsewhere, it would have been impossible to speak of an ICL sentencing jurisprudence. (19) Convicted war criminals, absent substantial mitigation, were killed. By the 1990s, however, international human rights law, which embraces the rehabilitative ideal but at the same time insists on a "just deserts" concept of proportionality in sentencing, had evolved so as to render it intolerable to continue to sentence all convicted ICL criminals to death--particularly given the aspiration of the international human rights movement to abolish capital punishment altogether. The judgments of the ad hoc tribunals now offer some tentative guidance on sentencing, but the jurisprudence has not, by and large, grappled with the difficult moral, legal, and practical questions raised by the ways in which ICL differs profoundly from national criminal justice. Resource constraints, which led the ad hoc tribunals to abandon distinct sentencing hearings at an early stage, also impeded the growth of a sentencing jurisprudence.

In Part IV, I argue that the expressive capacity of punishment best accommodates the confluence of ICL and international human rights law. I analyze the extent to which the standard justifications for punishment in national criminal law can or should be transposed to the distinct legal, moral, and institutional context of ICL. Each conventional account of punishment offers some insights that should be integrated into a comprehensive account of ICL's penal goals, but the highly distinct nature of ICL relative to national criminal justice compromises the coherence or efficacy (or both) of conventional crime control (deterrence, incapacitation, and rehabilitation) and retributive justifications for punishment. The principal value of ICL punishment lies in its expressive dimensions, which more accurately capture the nature of international sentencing and ICL's realistic institutional capacity to contribute to the ambitious objectives ascribed to it. International criminal tribunals can contribute most effectively to world public order as selfconsciously expressive penal institutions: publicly condemning acts deplored by international law, acting as an engine of jurisprudential development at the local level, and encouraging the legal and normative internalization of international human rights and humanitarian law. At the same time, international human rights law requires that the deterrent or retributive goals to which a focus on the expressive capacity of punishment may contribute be tempered and constrained by considerations of due process, rehabilitation, proportionality, and justice.

I conclude by briefly considering what practical guidance this account of ICL punishment offers for the substantive law and process of sentencing by international criminal tribunals. In particular, it counsels first, the institutionalization of sentencing hearings as a vital component of ICL trials; second, greater attention to context and the role of the defendant vis-a-vis any implicated collective entities (states, armies, tribes, and so forth) as relevant aggravating or mitigating circumstances and a jurisprudence that distinguishes rank-and-file perpetrators from the architects and orchestrators of ICL crimes (and those on the spectrum between these poles); and finally, efforts to increase the level and quality of jurisprudential exchange between international and national criminal justice institutions--for the efficacy of international criminal tribunals ultimately depends on their ability to contribute to the development and enforcement of ICL "at the local level, where all of us live." (20)

I stress that ICL, properly conceived, means more than international criminal tribunals, the focus of this Article; it includes the synergistic efforts of national and hybrid courts applying ICL, experiments with universal jurisdiction, and transitional justice mechanisms including truth commissions and lustration. I do not intend the account of ICL punishment and sentencing offered here as a universal answer to the sentencing issues faced by local and hybrid courts, some of which undoubtedly differ in degree and kind. It may, however, provide guidance, for the international goals of ICL sentencing should always, in my judgment, be factored into determinations of just punishment for ICL crimes.


Immi Tallgren rightly asks why "it generally seems to be taken for granted that whatever objectives and justifications work--or are supposed to work---on the national level should also, without any extra effort, cover the decisions and actions taken by states in concert." (21) Efforts to transpose general principles of criminal law common to many national legal systems to the substantially distinct moral, legal, and institutional setting of ICL may be misguided. Part of the problem, however, which I want to emphasize at the outset, lies in the overzealousness of some proponents, which creates unduly high expectations about what ICL can or should manage to accomplish. The ambitious goals ascribed to ICL include combating impunity, individuating guilt, promoting accountability, contributing to the reestablishment of international peace and security, deterring future atrocities, achieving retribution, creating an accurate historical record, and fostering both national and international reconciliation. (22) But it should go without saying that ICL can only be expected to augment, not substitute for, other strategies--diplomatic, economic, military, and developmental--to address serious human rights crises. (23)

Prospectively, international law must focus far more than it has in the past on developing and implementing prophylactic strategies to prevent large-scale human rights atrocities in the first place. Where those strategies fail, military intervention must, I believe, remain an option. (24) Retrospectively, international law should certainly combat a culture of impunity for human rights violations. But overemphasis on the ICL paradigm to the exclusion of alternative accountability mechanisms, such as lustration in the eastern European states of the former Soviet bloc or South Africa's innovative Truth and Reconciliation Commission, would be misguided and probably counterproductive. (25) ICL remains only one tool, and by no means always the most appropriate or efficacious one, for addressing the diverse circumstances that give rise to large-scale human rights atrocities and violations of the laws of war. (26) Even if international law now creates a duty to prosecute under some circumstances, (27) it surely does not prohibit complementary mechanisms for confronting the daunting political, social, and legal issues that face states emerging from internal strife, civil war, genocide, repressive regimes, and other circumstances in which widespread ICL violations characteristically occur.

Tragically, however, states historically fail to mobilize the political will to act to prevent or forestall mass atrocities until they reach horrific proportions--and often not even then. (28) The North Atlantic Treaty Organization's military intervention in Kosovo represented an encouraging, if controversial, precedent. Yet in retrospect, in the post-9/11 world and in view of the deplorable failure to take decisive action in Darfur, Kosovo appears to represent an exception enabled by a unique combination of circumstances rather than to herald a new era of multilateral interventions to prevent large-scale human rights atrocities. By contrast, since the end of the Cold War, states have shown both political will and enthusiasm for ICL prosecutions. With the advent of the ICC and the increasingly frequent invocation of universal jurisdiction by national courts, (29) ICL will probably continue to evolve rapidly at both the national and international levels.

We should continue to debate the merits (and demerits) of ICL as an international legal response to large-scale human rights atrocities, particularly because, insofar as undue attention to or reliance on ICL distracts from prophylactic strategies or excuses failures to take prompt action in the face of imminent crises, it emerges as no more than "cynical theater." (30) There is more than a little truth to the critique that international prosecutions in the wake of mass atrocities operate as a "fig leaf" to cloak and ameliorate the collective guilt of states and world leaders for their failure to intervene earlier or more decisively. (31) ICL's rapid development in the 1990s can be traced in part to the shameful failure of states to muster the collective political will to prevent or forestall systematic human rights atrocities, most notably in the Balkans and Rwanda. This may account for some of the unrealistic expectations about its short-term potential to achieve objectives like the reconciliation of states torn by ethnic conflict or genocide, or the restoration of international peace and security in a region.

But the origin of a practice neither defines its fixed purpose nor limits its potential utility. And realistically, retrospective prosecutions may at times be the only international legal response practically available given the constraints of international politics. In view of ICL's resilience and development, we should, I think, acknowledge that for better or worse, states have made a decision to devote considerable resources--intellectual, economic, diplomatic, and otherwise--to establishing an international criminal justice system for war crimes and human rights atrocities, at the heart of which lies the nascent ICC. Not as apologists but as realists, the relevant question then becomes not how ICL measures up against theoretically better or arguably more effective, but practically unavailable, international strategies, but rather, what goals can and should ICL realistically serve? How can we increase its efficacy and legitimacy?

We must also bear in mind that just as national criminal prosecutions represent only one component of a state's overall policy to control crime, which may include, in addition, policing strategies, social programs, education, economic development, and so forth, so international criminal prosecutions should be--and should be expected to be---only one component of a broader strategy toward international human rights atrocities. Tallgren, who offers a thoughtful critique of ICL based on flaws in the national law analogy, nonetheless recognizes that the critique itself relies on a somewhat unfair analogy: "The 'international criminal justice system' is assumed to function following the mechanisms of an idealized national system that cannot be localized anywhere." (32)

These qualifications aside, critiques of the analogy to national criminal justice raise many legitimate concerns. Foremost among them are issues raised by the nature and priority of the diverse community interests implicated by ICL; the corporate character of ICL crimes; and the often dramatically distinct sociopolitical context in which violations of ICL characteristically occur.


A. Nature of the Community: Proxy Justice, Global Stability, and Global Humanity

Systems of criminal law presuppose their value to one or more communities, (33) in the case of a national criminal justice system, to the community of that state's citizens. The imprimatur of a community distinguishes the unauthorized infliction of suffering from lawful punishment. (34) Punishment, in turn, is justified by its value to a community. Theories of punishment necessarily invoke the interests and values of the community that prescribes it to justify, by reference to its consequences or some perceived moral imperative, the legally sanctioned infliction of suffering. Deterrence, like incapacitation, seeks to protect the community from crime, whether by the same person or future putative criminals; rehabilitation strives to reform the criminal to promote his productive reintegration into the community; and retribution, unlike vengeance, is understood to vindicate certain communal norms and interests.

Punishment in national legal systems, for all its complexity, can be appraised in terms of the objectives of a single community or polity. Which communal interests ICL purports to serve is less clear. At times, we speak of ICL in terms of interests and values comparable to those identified with national criminal justice--for example, the rights and retributive interests of literal victims defined, typically, by nationality, religion, or ethnicity. In this regard, ICL emerges as a system of proxy justice for disenfranchised local communities victimized by widespread human rights atrocities. At other times, we emphasize the interests and values of the figurative international community, either as a community of states or in terms of the more elusive, somewhat mystical, notion of a community of mankind, a civitas maxima. To appraise punishment in the ICL context, we need to ask in the first place which community, literal or figurative, ICL should deem its principal referent, for the interests of different communities not infrequently conflict. (35)

To cite one well-known example of the tensions this can introduce: The International Criminal Tribunal for Rwanda (ICTR) has struggled, with very limited success, to strike the proper balance between the interests of the states that established it through concerted international action--states that maintain strong commitments to emerging international human rights norms--and the retributive penal interests of Rwanda and its nationals. The latter objected vociferously, for example, to the Security Council's decision not to authorize capital punishment in the ICTR Statute, (36) and to the ICTR's decision, since retracted, to release Jean-Bosco Barayagwiza, a notorious genocidaire, because of the prosecution's alleged violation of his due process rights. (37) Incidents like these highlight the not-infrequent tension between the interests of the figurative international community and those of the literal (local or national) communities that ICL also ostensibly serves. (38) International penal interests may, and hopefully will, overlap to some degree with those of the affected local communities. Still, instances of conflict, as in Rwanda, remain inevitable. (39)

The prevailing paradigm for ICL conceives of it "as a means of filling in for national justice," (40) that is, as proxy justice pursued by international institutions and actors on behalf of local communities victimized by international crimes. This view finds support in several comparatively recent developments in ICL. For purposes of sentencing, for example, the statutes of the International Criminal Tribunal for the Former Yugoslavia (ICTY) and the ICTR include a renvoi to the national law and practice of the former Yugoslavia and Rwanda, respectively. (41) Arguably, this implies a conception of the ad hoc tribunals as institutions designed to substitute for disabled national systems. In fact, we know that the drafters included these references to the general practice of the former Yugoslavia and Rwanda out of a conservative regard for the principle of legality, nullum crimen sine lege, nulla poena sine lege. (42) The ad hoc tribunals do not, in any event, consider themselves bound by the penal practices of these states. (43)

A far more compelling argument for the proxy-justice model of international criminal tribunals proceeds from the lauded principle of complementarity. To many, this principle, which conditions the admissibility of a case brought to the ICC on the characterization of the relevant state as "unwilling or unable genuinely to carry out the investigation or prosecution," (44) implies that the ICC acts as a substitute for national criminal justice systems disabled by a lack of political will or resources. In a technical sense, this may be true, (45) but it is also misleading. For a number of closely related reasons, international criminal tribunals do not, and as a practical matter, probably cannot offer proxy justice to the victims of serious human rights atrocities. (46)

Given their limited resources, international tribunals will never be able to prosecute more than a tiny fraction of the perpetrators of crimes that implicate hundreds, if not thousands. (47) The subset selected for prosecution has historically been, and will inevitably remain, contingent on discretionary political decisions made by international rather than local officials. (48) Of course, international lawyers increasingly agree that both practical and moral reasons counsel a strong, if not exclusive, focus on the leaders, orchestrators, and architects with the greatest responsibility for the crimes rather than the rank and file; (49) in a recent policy statement, the Prosecutor of the ICC expressly adopted this strategy. (50) But it will not always conform to the priorities of the victims, many of whom would naturally want to see the direct perpetrators of crimes affecting them or their kin punished. Their penal interests, understandably, will likely be more emotively retributive than those of a figurative international community invested in more abstract, long-term goals: ending the culture of impunity for human rights violators, contributing to the reestablishment of international peace and security, promoting the global rule of law, and so forth. (51) Experience with the ad hoc tribunals also consistently shows that local communities implicated by their work perceive them as distant, foreign, alien, and often illegitimate. (52)

Steps can and should be taken to improve the responsiveness of international tribunals to local needs and priorities. Trials, for example, might be held, where possible, in the state where the atrocities took place. (53) At their core, however, the problems identified above can only be reduced, not eliminated. They inhere in the nature and constitution of international criminal tribunals, with judicial and prosecutorial personnel, structures, statutes, and mandates established by states acting in diplomatic fora rather than by national leaders acting in national fora. With respect to the ICC, for example, its Prosecutor and judges, directly, (54) and the assembly of states parties, architecturally, not any particular local community, determine the priority and propriety of bringing particular cases. (55) These actors will exercise their discretion with foremost reference to the international interests they represent. (56) The ICC may be able to bolster local efforts at national justice and improve its solicitude for the victims, but it neither can nor should radically restructure itself in response to the highly divergent local circumstances and legal, political, and social cultures implicated by each situation referred to it. (57)

Complementarity recognizes (correctly, in my judgment) that national prosecutions, if genuine, feasible, and fair, more effectively serve the manifold goals ascribed to ICL than do international prosecutions. (58) Principal responsibility for controlling, judging, and punishing the conduct of individuals during times of war and other serious widespread violence must remain in the first instance on the highly organized, and often well-disciplined, collective entities--states, armies, and their cognates--implicated. ICL, in this regard, benefits from and indeed relies on the "dual positivization" of its legal norms. (59) Despite the vilification of the state in ICL discourse, we should always bear in mind, as Michael Ignatieff emphasizes in the context of international human rights enforcement, that the best guarantor of compliance with the laws of war and other ICL norms is not international law and institutions; it is a functioning state. (60)

But it does not follow that once an international tribunal assumes jurisdiction, it should conceive of itself or strive to function as a proxy for local interests. As a matter of functional capacity, it is doubtful that it can; as a matter of democratic legitimacy, it is unclear how it could. The avowed mission of international criminal tribunals, historically and today, is to prosecute "the most serious crimes of concern to the international community as a whole." (61) The drafters of the Rome Statute did not design the Court with a view to the satisfaction of local penal interests. Nor is the Court intended to replicate the process to which a defendant would be subject under an able and willing system of national criminal law. With regard to sentencing, the drafters deliberately omitted any reference to national penal law and practice in the interest of "equality of justice through a uniform penalties regime for all persons convicted by the Court." (62)

International criminal tribunals, unlike national courts, derive their authority from the concerted action of states, acting either pursuant to multilateral treaties (the International Military Tribunal for the Trial of German Major War Criminals (IMT) and the ICC) or under the authority of Chapter VII of the U.N. Charter, itself a multilateral treaty (the ad hoc tribunals for the former Yugoslavia and Rwanda). The Hobbesian notion of an implicit social contract--whereby individuals surrender certain rights to the state, which then gets a monopoly on legitimate coercion, in exchange for a measure of security--is strained in this context. And the concept of an international community is notoriously problematic and ambiguous. Unlike national communities, comprised of persons bound together by, at a minimum, territory, and, more often than not, by features such as values, language, culture, laws, history, and social norms, the international community defies a monolithic definition. Often, it functions as no more than a convenient shorthand for a broad array of global actors (including but not limited to states), processes, values, and interests. (63)

To develop a fair, principled, and consistent regime for international sentencing, however, we should nonetheless take seriously the project of identifying penal interests that reflect what we generally mean by an international community in the ICL context. A crime may be "of concern to the international community as a whole" because it threatens either state interests (the focus of traditional, Westphalian international law) or certain paramount values of mankind (a concept redolent of natural law and identified with the modern international human rights movement). To say that international criminal tribunals punish "the most serious crimes of concern to the international community as a whole" implies the latter meaning. The former, by contrast, generally calls to mind "transnational" crimes that can more effectively be investigated, prevented, or prosecuted through international regimes of cooperation, including treaties proscribing certain substantive conduct and extradition and other treaties facilitating procedural cooperation. (64)

In fact, ICL implicates both the shared values of humanity and the shared interests of states to varying degrees. Aggression, for example, leaving aside the intractable debate about its definition for the moment, (65) disrupts the peaceful and stable international order that the U.N. Charter regime strives to preserve, implicating the interests of the international community qua community of states. It also poses a widespread threat to life and liberty, core values of humanity and universal human rights, implicating the interests of the international community qua community of mankind. Equally, while widespread or systematic human rights violations that qualify as war crimes or crimes against humanity implicate primarily the international interests of mankind, (66) since the establishment of the ICTY, it has been recognized in international law that violations of ICL on this scale also endanger the international interests of states to the extent that they rise to the level of a threat to international peace and security within the meaning of Article 39 of the U.N. Charter. (67) This, after all, was the authority invoked by the Security Council for the establishment of the ad hoe tribunals for the former Yugoslavia and Rwanda. (68) In short, to adapt Michael Walzer's terminology, ICL violations may threaten both "global stability" and "global humanity." (69)

Giving primacy to transnational penal interests will inevitably cause friction with certain local communities, as it has in the past, but from a moral, institutional, and legal perspective, it more accurately and appropriately captures the values that punishment by international tribunals can realistically serve. Just as national criminal law conceives of crime as an offense against the state as a collective, not against the individual members of that collective immediately harmed by it, so ICL may be conceived analogously as concerned principally with the penal interests and values of the international community as a collective, not local political and social orders. (70) Rather than persist in the futile and impracticable effort to make genuinely international criminal tribunals mimic national courts by dispensing proxy justice, ICL should candidly acknowledge that these tribunals serve distinct goals and constituencies.

To avert misunderstanding, I stress that the jurisdiction of international tribunals should, in my view, remain the exception; indeed, as the Prosecutor of the ICC noted in a recent policy statement, "the absence of trials by the ICC, as a consequence of the effective functioning of national systems, would be a major success." (71) Where the jurisdiction of an international tribunal properly lies, however, it is by reference principally to international penal interests that an internally consistent, just, and principled sentencing scheme can be developed. The sentencing practices of the ICC cannot differ dramatically from case to case as a function of the national laws and practices of different affected states; they should not, that is, require the Court to impose disparate sentences for similar criminal conduct based on where the crimes took place or the nationalities of the victims. Whatever may be said about disparity in ICL sentencing more generally, that kind of disparity would raise grave doubts about the ICC's legitimacy. (72) Complementarity suggests that where state authorities can and will genuinely investigate or prosecute, international penal interests dissipate; where they cannot or will not, those interests become paramount.

In short, the authority and legitimacy of international criminal tribunals derive from and rely on international rather than local laws and values. National criminal justice for ICL violations should remain the norm. Hybrid courts offer a valuable alternative in situations in which the political will, but not the capacity, to investigate and prosecute exists. (73) But where an international tribunal assumes jurisdiction, international rather than local penal interests provide the more appropriate metric for evaluating the institution of punishment and developing an internally consistent, fair, and principled law of international sentencing.

B. Nature of the Crimes: Collectivity, Secondary Harms, and the Diffusion of Culpability

The transnational nature of the interests implicated by ICL should guide consideration of the goals to which any effort to develop principles of international sentencing should be directed. But the nature of the crimes and perpetrators--the moral circumstances in which they act and the collective character of the offenses--circumscribes the manner in which those goals can and should be pursued. ICL crimes share a collective or corporate character that distinguishes them from the bulk of national crimes; they can accurately be described, in some sense, as "collective" crimes. (74) To appreciate precisely how the collective nature of international crimes may bear on sentencing, however, we need to distinguish between several different senses, for they arguably cut in different directions vis-a-vis the primary sentencing metrics of harm and culpability. (75) In particular, international crimes can be described as collective in at least three ways: They may involve to varying degrees (1) collective perpetrators, (2) collective victims, and (3) a collective or corporate mens rea.

1. Collective Perpetration

George Fletcher offers a compelling argument to the effect that all international crimes necessarily involve a collective perpetrator, (76) generally a state, army, or similar authority. As a categorical claim, this view strikes me as mistaken. (77) But improbable counterexamples aside, it is surely correct that in the vast majority of cases, international criminals act on behalf of or in furtherance of a collective criminal project: waging aggressive war; destroying an ethnic, national, racial or religious group; carrying out a widespread or systematic attack against a civilian population or systematically violating the rights of protected persons under the Geneva Conventions. (78) For sentencing purposes, it suffices to accept that collective perpetration is, if not an indispensable element of each ICL crime, an almost invariable feature of each in practice.

2. Collective Victims

The second collective aspect of international crimes concerns the nature of the victim. With respect to some crimes, the collective nature of the victim is clear. To qualify as a crime against humanity, for example, one or more enumerated bad acts must be directed "against any civilian population." (79) Genocide, similarly, requires the specific "intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such," (80) and the ad hoe tribunals have emphasized that "the victim is the group itself, not merely the individual," (81) indeed, that "[t]he individual is the personification of the group." (82) Waging aggressive war, too, plainly involves a collective victim, typically another polity.

War crimes, however, present a more complex analysis. The Geneva Conventions require that the culpable act be perpetrated against a member of one of the protected groups: civilians, soldiers rendered hors de combat, or prisoners of war. (83) Yet war crimes do not involve a group victim in the same sense as crimes against humanity and genocide; they do not necessarily visit secondary harms on members of the targeted group, whether a civilian population or a national, ethnic, racial, or religious group. (84) Rather, "[t]he protected person requirement is better seen as a limitation on jurisdiction than an element requiring any particular mens rea on the part of the defendant." (85) As a practical matter, however, international tribunals have historically prosecuted systematic rather than isolated war crimes. The Rome Statute strongly reinforces this trend, vesting the Court with jurisdiction over war crimes "in particular when committed as part of a plan or policy or as part of a large-scale commission of such crimes." (86)

3. Collective Mens Rea

International crimes also characteristically involve a collective or corporate mental state, a consciousness of action on behalf of or in furtherance of a collective project. Crimes against humanity require knowledge of a "widespread or systematic attack directed against a civilian population." (87) Genocide, while theoretically a crime that can be perpetrated by a single person, as a practical matter almost always involves a shared specific "intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such." (88) Aggression (conceptually) and war crimes (characteristically) likewise involve consciousness of acting as part of a group--for example, a state, military unit or paramilitary organization--engaged in a common effort.

Legal philosophers frequently invoke Rousseau's distinction between two different sorts of collective action or intention: statistical or aggregative, on the one hand, and communal or associative, on the other. (89) "Collective action is communal," Dworkin writes, "when it cannot be reduced just to some statistical function of individual action, when it presupposes a special, distinct, collective agency. It is a matter of individuals acting together in a way that merges their separate actions into a further, unified, act that is together theirs." (90) International crimes implicate collective action and intention in this associative, communal, or corporate sense. The collective mens rea of a genocidal mob cannot be equated with the sum total of each individual genocidaire's mens rea. Rather, it is a shared, associative mens rea, a consciousness of being part of a common project, of acting as a group. Equally, waging war, obviously, is not a mere matter of each soldier engaging in combat with the enemy; it involves highly disciplined coordination and a chain of command. (91)

4. Implications for Sentencing

These aspects of collectivity, which may be present to varying degrees depending on the nature of the crime and the circumstances, arguably pull in different directions with respect to culpability. Consider first the collective nature of the victim. Several scholars and jurists, as well as the characteristic rhetoric of international law, suggest that this feature aggravates culpability. Danner, for example, advocating a view expressed by Judge Cassese in his separate opinion in the Tadic sentencing appeal, (92) offers a compelling case for regarding, say, a murder committed as a crime against humanity or act of genocide as more serious than the same act committed as a war crime, all other factors bearing on culpability being held constant. Genocide and crimes against humanity resemble bias crimes under national law and produce comparable secondary harms that render the same act more culpable. (93) From this perspective, the collective nature of ICL crimes arguably enhances culpability.

But the analogy to hate crimes, while offering important insights, seems incomplete. A collective victim, a racial, national or ethnic group, for example, characterizes hate crimes. But hate crimes do not necessarily evince collective perpetration or what might be termed the cloak of collective authority. To commit them, that is, individuals need not be associated with or acting on behalf of some collective, state, or organizational policy or practice. (94) By contrast, for international crimes, the collective character and authority of the perpetrator, as well as the associated corporate mens rea, in addition to the collective nature of the victim, characterizes the culpable conduct. These collective features of ICL crimes arguably diminish culpability insofar as they diffuse moral responsibility and counsel distributing "guilt among the parties to a criminal transaction," mitigating each perpetrator's guilt in some proportion to that of the collective. (95)

Again, however, the analysis remains incomplete, for these observations apply differently depending on the defendant's status and role vis-a-vis the crimes, "the individual circumstances of the convicted person." (96) On the one hand, the collective authority, power, and influence that enable military and civilian elites to orchestrate a genocide, to instigate a widespread or systematic attack against a civilian population, or to order, tacitly encourage or simply tolerate (by failing to prevent or punish) war crimes seems to call for a more severe penalty. (97) The participation, instigation, encouragement, or even tacit approval of a military or civilian elite often causes more aggregate harm than the individual crimes, however deplorable, of a rank-and-file participant. The cloak of collective authority poses a heightened danger, and its manipulation and abuse by elites should be penalized accordingly. (98) Conversely, for rank-and-file participants, acting within a collective context and often within a formal command structure, the collective nature of the crimes arguably reduces their culpability. To appreciate why, we need to consider not only the nature of the crimes but the sociopolitical context and psychology of the perpetrators.

C. Nature of the Perpetrators: Moral Agency in the "Maelstrom of Violence"

1. The Plausibility of Moral Choice

Collective crimes frequently evolve from collective pathologies. Reisman remarks that "many of the individuals who are directly responsible [for ICL crimes] operate within a cultural universe that inverts our morality and elevates their actions to the highest form of group, tribe, or national defense. After years or generations of acculturation to these views, the perpetrators may not have had the moral choice that is central to our notion of criminal responsibility." (99) Tallgren argues to similar effect that "the offender is likely to belong to a collective, sharing group values, possibly the same nationalistic ideology. In such a situation, the offender may be less likely to break the group values than the criminal norms." (100) Citing Hannah Arendt's well-known reflections on the trial of Adolph Eichmann, (101) Milgram's famous experiment, (102) and other research on the "criminological, psychological and sociological" characteristics of many ICL crimes and perpetrators, (103) he contends that "[c]ontrary to most national criminality which is understood to constitute social deviation, acts addressed as international crimes can, in some circumstances, be constituted in terms of conforming to a norm." (104)

The collective pathology of international crimes must, in my view, be factored into any morally and pragmatically defensible account of their punishment. But the assertion that many perpetrators of serious international crimes lack the kind of moral choice central to our ordinary conception of criminal responsibility may imply two very different objections: first, from a deontological perspective, that to punish behavior predetermined strongly or even absolutely by circumstances beyond a person's control is unjust; and second, from a utilitarian perspective, that such punishment is simply ineffective, for the person likely lacks the kind or degree of agency that makes the threat of sanctions an appreciable deterrent. I consider the latter objection below in connection with the analysis of deterrent rationales for punishment in the ICL context. Here, I want to explore the former objection.

I doubt that it is accurate in any meaningful legal or moral sense to conceive of ICL as a body of "criminal law that could be obeyed only by exceptional individuals" or to assert that the typical perpetrator "could not have acted or could not have been required to act otherwise." (105) To say that a person "could not have acted otherwise" may mean either that (1) given a strong form of philosophical determinism, no one can act otherwise than as he does, that the very concept of moral responsibility is incoherent; or more modestly, (2) given certain legal and normative assumptions about the conditions for voluntary action that beget criminal responsibility, a particular criminal "could not have acted otherwise" because one or more of those conditions did not exist in the circumstances in which he acted; for example, he lacked the kind or degree of control over his muscles or mind that humans ordinarily possess (or believe they possess). (106)

The former argument, that perpetrators of international crimes lack moral choice, that is to say, choice of a kind or to a degree sufficient to justify punishment, is a variant of a familiar reductio ad absurdum argument about determinism and responsibility, the "argument from causation," (107) which Michael Moore expresses succinctly in this syllogism:

1. All human actions and choices are caused by factors beyond the actor's control (the determinist premise).

2. If an action or choice is caused by factors beyond the actor's control, then that action or choice is morally excused (the moral version of the causal theory of excuse).

3. If an action or choice is morally excused, then that action or choice should not be legally punishable (the theory of punishment making moral culpability at least a necessary condition of legal liability). Therefore:

4. No action and choices should be legally punishable (the conclusion of universal legal excuse). (108)

Few, however, really mean to challenge ICL's legitimacy based on this syllogism. While it is entirely coherent, which is not to say correct (109) it would impugn not only the moral basis of ICL (and, for that matter, our intuitions about national criminal law) but also many central precepts of civil law, such as the voluntarist assumptions of contract law and the principle of fault in tort law. Perhaps the strong form of philosophical determinism is accurate, but no legal system can genuinely incorporate it and still function. (110) No legal system operates on the assumption that no one can be held responsible for anything, that all conduct can ultimately be traced to some combination of hard-wired internal circumstances, themselves a product of either nature or nurture, and external circumstances--neither of which leaves room for a meaningful conception of moral choice. The law operates in the realm of normative ethics, not metaethics.

For this reason, it does not suffice to point to circumstances like war, nationalistic fervor, or interethnic violence and assert categorically that voluntary conduct sufficient to beget criminal responsibility under those circumstances is a fiction. Perhaps extreme circumstances simply make it easier to recognize that moral choice is always a fiction; they differ in degree but not in kind. This form of hard determinism, in the ICL context, also does not explain why the figurative compulsion created by circumstances of war, mass violence, collective psychology, and so forth should be qualitatively more problematic for the concept of moral choice than any other causal factor, say, extreme socioeconomic deprivation. Consider the "rotten social background" defense: that a defendant's economic and social background "so greatly determines his or her criminal behavior that we feel it unfair to punish the individual." (111) At the theoretical level, given the strong form of determinism, it is not clear that the excuse of duress, that the defendant had no choice but to act as he did because of physical coercion, really differs from the "rotten social background" defense, that the defendant had no choice but to act as he did because of overpowering hard-wired impulses attributable to his socioeconomic circumstances. Both defenses assert that certain causes, whether a "gun to the head" or socioeconomic determinants, effectively deprive a person of the agency required for moral choice and criminal responsibility.

The point here is not to take sides in this perennial philosophical debate; it is only to say that if we truly believe ICL punishment cannot be justified where war criminals and genocidaires "could not have acted otherwise," that phrase must not be understood as a global claim about determinism but, more modestly, as an assertion that certain legal and normative assumptions we make about the conditions for voluntary action that beget criminal responsibility do not exist under the circumstances. Yet the nature and scope of the objection have never been articulated. The real task for international criminal lawyers involves working out what conditions vitiate moral or legal responsibility and why. (112) Did the person act under duress, unusual provocation, fear, or diminished mental capacity? If so, should those conditions exonerate or only mitigate punishment? The question, in the words of the IMT, "whether moral choice was in fact possible," (113) must be considered against the backdrop of the general philosophical presumptions common to modern legal systems: agency, moral responsibility, culpability, and so forth. (114) This is not to suggest that the dramatically distinct circumstances characteristic of ICL violations and the collective character of the crimes should be disregarded; to the contrary, they compel serious attention. But categorical assertions about the nature (or lack) of moral choice evade rather than offer guidance on the practical questions that international criminal tribunals must address: to what extent such circumstances should be deemed exculpatory, aggravating, or mitigating.

2. Beyond Caricatures

Several competing visions of the perpetrators of ICL crimes predominate in the literature arguably relevant to these questions. On one, rooted in the social, historical, and psychological studies referred to earlier, war criminals, genocidaires, and other participants in large-scale or systematic human rights atrocities emerge as automatons enslaved by a mob mentality, incited by ethnic, national, racial, or religious hatred, and so strongly predisposed to criminal conduct that it arguably makes little sense to regard them as moral agents accountable for their actions. (I stress that in practice few defendants prosecuted by international tribunals resemble this caricature.) The Rwandan genocide, in which thousands of Hutus systematically slaughtered Tutsis with machetes and other rudimentary weapons offers an (arguably) compelling example of this view. (115) Consider, too, the child soldiers enlisted by the Lord's Resistance Army, the subject of the ICC's first investigation: Abducted as minors, compelled to kill and fight under duress, and socially and psychologically conditioned to commit acts of extraordinary brutality and violence, (116) it surely makes little sense, from either a retributive or consequentialist perspective, to prosecute and incarcerate them. Non-punitive rehabilitation would be both more appropriate and more effective.

On another view, however, in tension with but paradoxically also closely related to the first, the prototypical war criminal or genocidaire emerges as Hannah Arendt's Adolph Eichmann, the model of bureaucratic and calculating, but at the same time banal, evil. While this vision, like the former, characterizes the perpetrator as "ordinary," it elicits very different intuitions about the propriety of applying the criminal law paradigm. The rank-and-file international criminal is not conceptualized as a mindless instrument of the architects of ICL crimes, inculcated with ethnic hatred and psychologically conditioned to act as he does, but rather as an ordinary person who consciously chooses, albeit in an aberrant sociopolitical context, to participate in knowingly horrendous acts, often for social, political, or economic gain. This vision of the quintessential calculating bureaucrat, unlike the alternative one of the rank-and-file perpetrator acting under the figurative compulsion of psychological, social, and political circumstances, offers a far more compelling moral case for applying the criminal law. Civilian and military elites present yet another paradigm: Far from being unable to act otherwise, they personify the cynical, deliberate, and calculated instigation of ICL crimes as a tool in the service of greed or power.

None of these caricatures, of course, accurately portrays the nature of all war criminals and genocidaires or captures the tremendously complex constellation of factors that may lead persons to engage in unconscionable crimes. It seems equally misguided to either denounce or condone the propriety of applying principles of national criminal law to ICL crimes on the basis of them. What we need is greater sensitivity not only to the gravity of the crime, but to the individual circumstances of the defendant, in particular his role and background. ICL undoubtedly seeks to regulate and judge conduct in circumstances of war, ethnic violence, and other extreme conditions that differ radically from those prevailing in a well-ordered, peacetime society-circumstances that arguably expose the tenuousness of common assumptions about moral choice, responsibility, and culpability. To some degree, however, those assumptions underlie the criminal law generally; they do not, by themselves, constitute a global objection to ICL. Rather, the radically different circumstances in which ICL violations typically occur affect how, not whether, these assumptions apply. The extent to which the conventional rationales for punishment can or should be transposed to ICL depends on paying closer attention to the nature and circumstances of the violations, a process most effectively addressed not in the context of trial, where the determination of guilt or innocence rightly predominates, but at sentencing.


A. Postwar Origins

How well has ICL sentencing addressed these issues? The historical record is poor. ICL's components, especially the laws of war, originated well before Nuremberg, and history offers several early examples of international efforts to prosecute war criminals and other perpetrators of what would now be defined as ICL crimes. (117) But the discipline of ICL as a distinct legal field originated in the aftermath of World War II. Regrettably, if understandably, the emotive atmosphere in which it developed did not conduce to sustained consideration of the goals of punishment and sentencing. At the time, the very notion that the most culpable Axis leaders and war criminals, men like Goering, should be subjected to the unwieldy and costly processes of the law proved controversial. Far from raising questions about the rationale for their punishment, international criminal trials emerged as an alternative to the proposal, espoused by Winston Churchill among others, that Axis leaders be summarily executed by firing squad. In the oft-quoted statement of Anthony Eden, then Britain's Foreign Secretary, many felt that the Axis leadership's "guilt was so black" that it fell "beyond the scope of any judicial process." (118) While the American, French, and Soviet position in favor of the establishment of an international tribunal ultimately prevailed, no one questioned that the sentence for the major architects of the Axis crimes, absent very compelling mitigating factors, should be death. (119) Customary international law at the time also prescribed capital punishment for war crimes. (120)

The IMT Charter therefore authorized "death or such other punishment as shall be determined ... to be just," (121) and the International Military Tribunal for the Far East (IMTFE) adopted this skeletal sentencing provision verbatim. (122) The judgments of each paid scant attention to sentencing. Neither held distinct sentencing hearings. (123) Despite a few isolated statements justifying international punishment by reference to its presumed deterrent value, (124) the principal impetus for punishment after World War II consisted of an emotive reaction to the sheer magnitude and unconscionability of the crimes. Insofar as a coherent penal theory can be inferred from the postwar trials, it seems to be a crude retributivism, (125) notwithstanding Justice Jackson's famous remark in his opening statement before the IMT: "That four great nations, flushed with victory and stung with injury, stay the hand of vengeance and voluntarily submit their captive enemies to the judgment of the law is one of the most significant tributes that Power has ever paid to Reason." (126)

B. International Human Rights: Abolitionism, Proportionality, and the International Rehabilitative Ideal

In time, however, international human rights law evolved to aspire to abolish the death penalty, and more generally, to emphasize rehabilitation as the paramount goal of punishment. (127) The International Covenant on Civil and Political Rights, for example, limits the application of the death penalty with a view to its ultimate abolition and describes "reformation and social rehabilitation" as "the essential aim" of incarceration. (128) Indeed, a number of European states regard life imprisonment as "cruel, inhuman or degrading punishment" contrary to modern human rights norms. (129) These developments, of course, sit uneasily with the sentencing practices of the postwar tribunals. International law also embraces proportionality in sentencing as a general principle of law. Contemporary international criminal tribunals must develop some principled way to distinguish between crimes that, in their sheer magnitude and brutality, all seem to demand severe punishment. (130) Surely, Dusko Tadic, notwithstanding a conviction for crimes against humanity and war crimes that included horrific acts of murder and torture, should not be deemed as culpable or sentenced as severely as Jean Kambanda, the former interim prime minister of Rwanda and a principal architect of the genocide. But it is unclear what factors should be considered to arrive at an appropriate sentence for each--or for those defendants that do not fall clearly into the polar categories of "big fish" and "small fry."

International human rights law thus renders the retributivist impulse for ICL punishment, as manifested in the post-World War II trials, conceptually and practically problematic. It is difficult to conceive of a punishment other than death that could fit most serious ICL crimes in a talionic sense. Yet authorizing capital punishment in constitutive ICL instruments would undermine international efforts to abolish it categorically. More generally, it is far from clear that terms of incarceration imposed by international tribunals can, even assuming they should, rehabilitate serious war criminals and genocidaires. Until recently, few ICL judgments even mentioned rehabilitation as a sentencing objective; (131) some explicitly discounted its value or propriety. (132) The sentencing judgments of the ad hoe tribunals refer variously, and without much elaboration or consistency, to retribution and deterrence as the twin goals of sentencing. (133)

C. The Beginnings of an ICL Sentencing Jurisprudence

The ICTY and ICTR Statutes represent only a slight improvement over their predecessor instruments in this regard. Each contains a skeletal provision vesting the tribunals with discretion to impose a term of imprisonment based on "such factors as the gravity of the offence and the individual circumstances of the convicted person"; a renvoi to the national practice of the former Yugoslavia and Rwanda, respectively; and a provision for restitution. (134) The Rules of Procedure and Evidence developed by the tribunals augment this minimal framework, but only in abstract terms, providing for consideration of aggravating and mitigating circumstances, without specifying which factors might qualify. (135) The jurisprudence of the tribunals has gone some way toward filling out these gaps. Both the ICTY and ICTR have considered a variety of aggravating and mitigating factors, including, in the former category, "leadership (superior) position of the accused, terrorizing victims, sadism, cruelty and humiliation, espousal of ethnic and religious discrimination, and the number of victims"; and in the latter, "superior orders, necessity, duress, voluntary intoxication, automatism, insanity, and self-defense," as well as "entry of a guilty plea and acceptance of responsibility, remorse, voluntary surrender to the tribunal(s), 'substantial' cooperation with the prosecutor, post-conflict conduct, previous good character, benevolent attitude toward the victims, and age." (136)

These factors largely mirror those common to national legal systems. (137) Notably absent is any explicit consideration of the social, political or psychological circumstances characteristic of war and other large-scale violence; or of the collective nature of the crimes--factors which may, depending on the status of the accused, either aggravate or mitigate individual culpability. In Prosecutor v. Krstic, the ICTY said that,
   [i]n determining the appropriate sentence, a distinction is to be
   made between the individuals who allowed themselves to be
   drawn into a maelstrom of violence, even reluctantly, and those
   who initiated or aggravated it and thereby more substantially
   contributed to the overall harm. Indeed, reluctant participation
   in the crimes may in some instances be considered as a
   mitigating circumstance. (138)

That statement, however, stands virtually alone in the jurisprudence; the tribunals have implemented it, if at all, haphazardly. (139)

ICL sentencing has thus evolved from retributive origins at Nuremberg to an increasingly nuanced body of law that recognizes the complexity of punishment in the context of catastrophic violence or war, defying the simple classification of ICL violations as obviously calling for the death penalty. At the same time, confusion about the justifications for punishment and its distribution among different kinds of defendants plagues the jurisprudence. (140)

Furthermore, while the judgments of international criminal courts often describe the crimes as comparatively more severe than crimes of violence under national law, such as murder, (141) the penalties imposed for them often seem incongruously lenient, at least by a retributive metric. (142) The ICTR recently noted, for example, that rape, torture, and murder as crimes against humanity have been punished by average sentences of, respectively, between twelve and fifteen years, five and twelve years, and twelve and twenty years." (143) In short, the present state of the law on international sentencing resembles in a number of respects that of the indeterminate federal sentencing system critiqued by Judge Frankel in his famous polemic, Criminal Sentences: Law Without Order. (144)


Conventional justifications for punishment fall into two broad categories: crime-control and retributivist theories. The former includes deterrence, specific and general; (145) incapacitation, which can be conceived as an extreme form of specific deterrence insofar as, if successful, it obviates any recidivism concerns; (146) and rehabilitation. The latter, retributivism or "just deserts," though often conceived in Kantian terms, originated in theological conceptions of justice, and from an anthropological perspective, in the lex talionis common to many early legal systems.

Given the diversity of transnational penal interests and the diversity of views about what counts as an appropriate justification for punishment, (147) it would be misguided and likely futile to offer a monolithic theory about the goals of international sentencing. (148) Furthermore, particularly in the international context, it is important to bear in mind H.L.A. Hart's insight that the "general justifying aim" for punishment need not be coterminous with the justification for its application or proper distribution in concrete cases: the questions "why punish," "who should be punished," and "how much should they be punished" may be usefully distinguished. (149) Most ICL scholarship addresses the former, logically antecedent, question: Why establish an international criminal justice system? But as we move from theory to practice, from the justification for an international system of punishment to the operationalization of that system, we confront, in the end, individuals rather than abstractions. The rhetorical goals of international justice offer little guidance on whether the gravity of a defendant's crimes and his individual circumstances call for a term of incarceration of five years, twenty-five years or life.

Each conventional goal of punishment in national law offers insights, but analysis of the extent to which retributive and deterrence theories can or should be coherently transposed to the international context reveals that the primary value that international punishment can realistically serve consists in its expressive functions. (150) An expressivist account of punishment best captures both the nature of international sentencing and its most promising institutional capacity to make a difference given the momentous political and resource constraints that international tribunals inevitably face, for ICL's ability to contribute to crime-control and retributive goals ultimately depends in large part on its value, legitimacy, and persuasiveness as authoritative expression. This conclusion counsels more attention to the sentencing process than international tribunals have historically paid.

Expressivism is not or need not be, strictly speaking, a self-sufficient "justification" for punishment; (151) it is a function and essential characteristic of punishment as a social institution. Incarceration and other forms of "hard treatment" do not impose suffering only, or even primarily, as a means to deter crime or to exact a debt owed by the criminal to society. Rather, "punishment is a conventional device for the expression of attitudes of resentment and indignation, and of judgments of disapproval and reprobation, on the part either of the punishing authority himself or of those 'in whose name' the punishment is inflicted. Punishment, in short, has a symbolic significance largely missing from other kinds of penalties." (152)

As a descriptive matter, expressivism aptly captures the nature of ICL punishment and the characteristic tenor of the sentencing judgments of the ad hoc tribunals. (153) By punishing the perpetrators of serious international crimes, to paraphrase Feinberg, the international community attempts authoritatively to disavow that conduct, to indicate symbolically its refusal to acquiesce in the crimes, to vindicate international human rights norms and the laws of war, and to absolve ethnic or national communities, as collectives, of guilt by punishing individual perpetrators. (154)

As a normative matter, the expressive functions of punishment can be transposed to the distinct moral and institutional context of ICL without straining the coherence of the national law analogy, for expressivism self-consciously focuses less on the immediate instrumental value of punishment-as a tool of either retribution or deterrence on the rational actor model--and more on the long-term normative values served by any system of criminal law. It may well be quixotic to expect ICL to exert a significant deterrent effect on war criminals and genocidaires merely through its potential to increase the perceived costs of international crime. It may well be morally problematic for international tribunals, which represent and serve the interests of a figurative international community, to regard themselves as agents of retribution on behalf of victims who often regard them as illegitimate or worse. But international sentencing holds the potential effectively to fulfill the expressive function of punishment by conveying its distinctive symbolic significance. (155) And insofar as deterrent and retributive theories of punishment can be transposed to the ICL context notwithstanding flaws in the national law analogy, it is largely because of the expressive dimensions of punishment.

A. Deterrence

1. The Benthamite Model

Human rights activists, diplomats, scholars, prosecutors, jurists, and journalists alike frequently ascribe the recurrence of large-scale human atrocities to impunity, (156) by which they generally mean the absence of criminal punishment. Kenneth Roth, the executive director of Human Rights Watch, argues that "[b]ehind much of the savagery of modern history lies impunity. Tyrants commit atrocities, including genocide, when they calculate they can get away with them." (157) Writing in favor of the ICTY, Theodor Meron, now one of its judges, suggested that "[a]bandoning the tribunal now would have a negative impact on the behavior of the parties to the conflict.... On the ground, those committing war crimes would infer that regardless of their past or future violations they will not be held criminally accountable by the international community." (158) On this view, punishment deters because potential war criminals know and fear the consequence of the law, that is, the pain of incarceration, and act to avoid it. (159)

But in the first place, deterrence, so conceived, requires the credible and authoritative communication of a threatened sanction. The figurative nature of the international community poses tremendous obstacles to this enterprise. It is one thing for a criminal justice system clearly to communicate a threat within a literal community, for example, a state or political subdivision, where constituents speak the same language, share sources of information, witness, at least intermittently, the operation of the machinery of the criminal justice system (police, courts, etc.), and ideally have good reason to believe, as Holmes wrote, that the law will keep its promises. (160) It is quite another for a culturally foreign and geographically distant tribunal, which lacks its own police force and enforces the law sporadically and inconsistently at best, to communicate a credible threat authoritatively, particularly where local norms, as Arendt and others have emphasized, may point strongly in the opposite direction.

Second, if the rational-actor model of deterrence is suspect in the national context, it is exponentially so in the international, where war, largescale violence, and collective pathologies, as well as the institutional and resource limitations of ICL, can be expected to distort the viability of the familiar cost-benefit calculus on which that model depends. It is doubtful that the average war criminal or genocidaire weighs the risk of prosecution, discounted by the likelihood of apprehension, against the perceived benefits of his crimes. And even if he does, "it is not irrational to ignore the improbable prospect of punishment given the track record of international law thus far." (161)

Third, the collective nature of ICL crimes means that "group think," undue obedience to authority, and other phenomena familiar from the social psychology research canvassed by Fletcher and Weinstein may well interfere with this kind of calculation. (162) Bentham wrote that punishment cannot deter "[w]here the penal provision, though it were conveyed to a man's notice, could produce no effect on him, with respect to preventing him from engaging in any act of the sort in question." (163) While he had in mind circumstances like infancy, insanity, and intoxication, the principle applies equally to any psychological or physical condition that negates or overrides the fear of penal sanctions. The chaotic circumstances of war, large-scale violence, ethnic conflict, or genocide clearly qualify.

We should avoid overstating these critiques. They do not show that, for ICL, "deterrence doesn't work." (164) In the first place, skepticism about deterrence is not unique to ICL. Within nation-states, too, the evidence supporting general deterrence is inconclusive and difficult to interpret. (165) Few believe that would-be war criminals will "read the resolutions of the Security Council and stop their grave violations of international humanitarian law" or "be indoctrinated to refrain from further breaches of the law and to support the shared values of the international community if one of [their] co-fighters ... receive[s] a 15-year prison sentence in the Hague." (166) But equally, few believe that "ordinary" murderers consult national penal statutes and undertake cost-benefit analyses before killing.

Furthermore, as emphasized earlier, it would be misguided to assimilate all war criminals and genocidaires to a single psychosocial profile, say, that of the paranoid automaton, inculcated with hatred and psychologically conditioned to act as he does by propaganda, social pressure, primordial cultural influences, and so forth. Often, elites responsible for large-scale or systematic international crimes can be described accurately as "conflict entrepreneurs," those who manipulate values and the tools of state power as a means to aggrandize their own social, economic, or political power. (167) This vision of the typical criminal not only seems intuitively more blameworthy than the rank-and-file perpetrator swept up in the "maelstrom of violence," but also, perhaps, more deterrable. While elites may calculate that the risk of apprehension and prosecution remains insignificant, the fact remains that they calculate, weighing costs and benefits in a manner that seems more susceptible to external incentives.

Finally, the power of ICL to disempower elites through stigma and reputational injury should not be underestimated. "Leaders may be desperate, erratic, or even psychotic, but incitement to ethnic violence is usually aimed at the acquisition and sustained exercise of power.... Momentary glory and political ascendancy, to be followed by downfall and humiliation, are considerably less attractive than long-term political viability." (168) In this regard, the mere issuance of an indictment, the very prospect of a trial, is itself the "punishment" by which ICL may deter. While the deterrence value of ICL, conceived in utilitarian terms, remains largely aspirational, available empirical evidence does suggest that it has "dissuad[ed] some war crimes," albeit not "general programs of extermination," and its prospects may be enhanced by a "relatively credible threat of prosecution" where it matters the most, that is, relative to elites. (169)

Still, to paraphrase Jeffrey Murphy's summary of the problems with deterrence generally: Some war criminals and genocidaires do not weigh the costs and benefits of criminal conduct in a dispassionate way (though it would likely be wrong to say that they act irrationally relative to their perceived interests). Others, particularly megalomaniacal elites, calculate (often correctly), that they will get away with it, or that the risk of apprehension and prosecution remains small. Still others may be so idiosyncratically devoted to genocide or ethnic cleansing as to be "undeterrable by anything short of massive military force, and maybe not even that." (170) Often, the chief war criminals will be coterminous with a state's political elite; national prosecutorial and judicial institutions may be too corrupt or subservient to that elite class; and ordinary moral norms about the treatment of other human beings may be eroded, if not inverted, by the circumstances of war or perceived crisis. While some elites may be susceptible to deterrence on the rational-actor model, other megalomaniacal tyrants--Milosevic, Pol Pot, Idi Amin, "Emperor" Bokassa--tend to share a psychological sense of infallibility and invulnerability that makes it less likely that they will rationally weigh the real probability of apprehension and prosecution, even if it can be increased, against their immediate goals: power, territorial acquisition, or obliteration of an ethnic group. (171) In his opening statement at Nuremberg, Justice Jackson emphasized that "[p]ersonal punishment, to be suffered only in the event the war is lost, is probably not to be a sufficient deterrent to prevent a war where the war-makers feel the chances of defeat to be negligible." (172)

Because of the institutional and resource constraints that plague international tribunals, their mere existence cannot be expected to enhance the prospects for deterrence very much. Their efficacy depends more on their ability to contribute to the growth and development of national laws, ethical norms, and institutions, as well as to encourage and, at times, compel national criminal justice systems genuinely to investigate and prosecute. For this reason, the expressive value of ICL sentences--the extent to which they convey, reinforce, and encourage the growth of national legal and moral norms that conform to ICL--matters more than the relative severity of the punishment in any individual case. International criminal tribunals will deter most effectively, on the Benthamite model, if they encourage the growth of national institutions, laws, and ethical norms that can be applied with greater regularity and frequency.

2. The Moral Educative Model

General deterrence operates not only, or even primarily, through external restraints, that is, because subjects hear and fear the relevant sovereign's commands backed by threats. (173) The criminal law also deters through its long-term role in shaping, strengthening, and inculcating values, which encourages the development of habitual, internal restraints: (174) "The law can discourage criminality not just by 'raising the cost' of such behavior through punishments, but also through instilling aversions to the kinds of behavior that the law prohibits." (175) In the long term, this effect of punishment likely deters far more criminal conduct than conscious rational calculation based on a fear of sanctions. Most people do not resemble Holmes's "bad man," obeying the law based only on "a prophecy that if he does certain things he will be subjected to disagreeable consequences by way of imprisonment or the compulsory payment of money." (176) In general, "the most effective form of law-enforcement is not the imposition of external sanction, but the inculcation of internal obedience." (177) Payam Akhavan, a strong proponent of this view relative to ICL, argues that criminal sanctions
   instill voluntary or "good faith" respect for just conduct by
   discrediting inhumane or unjust conduct, the cumulative effect
   of which encourages habitual or subliminal conformity with
   the law. Thus, the prevention of future crimes is necessarily a
   long-term process of social and political transformation,
   entailing internalization of ideals in a particular context or
   "reality," or the gradual penetration of principles into given
   power realities. (178)

This claim, however, brings us back full circle to the political, social, and psychological issues flagged earlier. Deterrent mechanisms that rely on internal restraints, habituation to moral and legal norms, require a criminal justice system perceived as authoritative and legitimate. (179) But many targets of ICL, persons willing to perpetrate unconscionable crimes, do not regard the system in that way. (180) The rank and file, acting under the figurative compulsion of an inverted morality or collective pathology whereby ordinarily "prohibited conduct starts to appear as a holy obligation, a positive achievement," will be unlikely to view their conduct as deviant relative to the community norms that matter most, that is, local ones. (181) As for the elite, those who manipulate values in the service of power, they already, by hypothesis, lack the internalized norms by which the moral-educative effect of punishment is thought to operate.

Finally, at least one study "suggests that the internalization of norms is not sufficient to prevent atrocities." (182) David Wippman, reviewing findings of the International Committee of the Red Cross (ICRC) on war crimes in Bosnia-Herzegovina, notes that the ICRC concluded that such norms, while fully understood, supported, and accepted by combatants and civilians alike, "broke down under the pressure of nationalist passions and hatred. They also broke down because a range of other wartime considerations diminished and superceded them." (183)

These observations suggest that once the social, cultural, or political circumstances for the widespread manipulation of moral norms obtain, the efficacy of ICL as a mechanism of deterrence is slight. As much as possible, we should strive to prevent, not only individual criminal acts, but the emergence of the sociopolitical circumstances that breed mass atrocities in the first place. (184) Prophylactic strategies intended to address the roots of conflict and to forestall, for example, the emergence of "failed states" or the polarization of ethnic and national groups should be the principal focus of international efforts. To the extent that ICL distracts from these objectives, it is counterproductive. ICL would more effectively contribute to the process of norm internalization and stabilization by maximizing its synergy with other mutually reinforcing strategies, including communications, development assistance, international human rights policy, the spread of liberal constitutionalism and democracy, diplomacy, and economic incentives.

Analysis of the viability and coherence of deterrence in ICL thus yields two overarching conclusions relevant to sentencing: First, it supports Danner's view, echoing H.L.A. Hart, that while deterrence may offer sound reasons to establish an international criminal justice system, it provides scant "guidance in determining the lengths of particular sentences." (185) Judges in the international context, even more than in the national, lack sufficient, and sufficiently reliable, information to assess logically the "costs and benefits of imposing a sentence of any particular length in individual cases." (186) Second, punishment's absolute severity in quantitative terms matters less than its relative severity as an expression of the condemnation that attends particular criminal acts under the circumstances. A sentence that local institutions and actors view as cogent, legitimate, authoritative, and persuasive, one disseminated to the broadest possible audience, may contribute to the long-term project of preventing ICL crimes through mediums other than direct communication of a threat to potential criminals--for example, by its influence on national jurisprudence, rules of conduct integrated into military manuals distributed to soldiers, the media, and in the long term, the values and perceptions that predominate "in the elite culture of international diplomacy as well as world public opinion in general." (187)

B. Retribution

Retributive justifications for ICL punishment, while historically predominant, emerge as problematic from several perspectives. Above all, despite the prevalence of secular philosophical versions, retributivism--with its characteristic discourse of "just deserts," blameworthiness, and the restoration of some moral balance--remains strongly redolent of religious notions of justice ill-suited to a diverse international community of states and peoples. (188) And secular justifications for retributivism transposed to the ICL context make little sense largely because they presuppose a more coherent, univocal, and stable community than international law offers.

1. Retribution as Vengeance Regulation

One prevailing legal-anthropological model of retribution--which strictly speaking, should be regarded as a kind of utilitarianism--views it as a socially condoned substitute for vengeance. (189) "The criminal law," in Stephen's oft-quoted maxim, "stands to the passion of revenge in much the same relation as marriage to the sexual appetite." (190) Acts of retaliatory violence, if left unchecked, threaten to destroy the social bonds of the community. The institutions of criminal justice must therefore enable the discharge of instinctual desires for vengeance in an orderly, socially palatable manner. Punishment, on this view, is the means by which the state terminates the otherwise escalating cycles of retaliatory violence within its community. (191) Rene Girard argues, for instance, that ritual sacrifice in ancient societies prevented their self-destruction, precipitated by the escalation of cycles of retaliatory violence. (192) The criminal law gradually assumes the role of regulating private vengeance or, euphemistically, administering justice. (193) Failure to fulfill this function culminates in the chaotic discharge of retributive instincts, characteristically in the form of large-scale violence.

The anthropological vision of escalating blood feuds and patterns of collective violence conjured by Girard's thesis resonates with our view of the cataclysmic circumstances caused by war, chaotic collapse of the state, and mass violence that characterize cases of widespread ICL violations like, for example, the cycles of interethnic violence between Hutus and Tutsis in twentieth-century Rwanda or Croats and Serbs in the Balkans. (194) Indeed, as Arendt wrote, despite some perfunctory nods in the direction of deterrence, Eichmann's trial remained fundamentally about retribution in this theological, quasi-talionic sense:
   We refuse, and consider as barbaric, the propositions "that a
   great crime offends nature, so that the very earth cries out for
   vengeance; that evil violates a natural harmony which only
   retribution can restore; that a wronged collectivity owes a duty
   to the moral order to punish the criminal" (Yosal Rogat). And
   yet I think it is undeniable that it was precisely on the ground
   of these long-forgotten propositions that Eichmann was
   brought to justice to begin with, and that they were, in fact, the
   supreme justification for the death penalty. (195)

Some prominent jurists and scholars ascribe a comparable function to the ad hoc tribunals. (196)

On reflection, however, this view of retribution as a response to modern ethnic "blood feuds"--and arguably, therefore, a proper rationale for ICL punishment--makes little sense. In the first place, the figurative nature of the international community renders the paradigm inapposite. Retributive views of punishment rooted in lex talionis, (197) whether anthropological or philosophical, depend on a conception of justice as a value that arises within a single, coherent community. ICL, however, must mediate between the interests of multiple communities, both literal and figurative, and international tribunals generally lack the local legitimacy required as a practical matter to discharge the anthropological function of vengeance regulation. They represent the amorphous international community rather than the literal "wronged collectivity," that is, the particular local community purportedly "unbalanced" by the crimes. The personnel, rules, and institutions that comprise international tribunals conform to and promote international rather than local legal, social, and moral norms. It is far from clear how punishment by an international tribunal, which derives its authority from either treaty or a Security Council resolution (at bottom, a function of state consent to the U.N. Charter, itself a multilateral treaty), can be a legitimate proxy for the penal interests of the literal victims who suffer extraordinary crimes of violence. This disjuncture may well be a major reason that international tribunals often suffer from a perceived lack of legitimacy in relation to affected local communities or states.

And even were international tribunals able to act as proxies for disabled local institutions, the collective nature of international crimes renders the idea of punishment as the socialized discharge of communal instincts for vengeance misguided at best: What sense does it make to speak of a "wronged collectivity" where that very collectivity, in many cases, bears some culpability or moral responsibility for the relevant wrong? We can see this problem more clearly by turning to the conventional philosophical justifications for retribution, which, unlike Girard's anthropological vision, insist on the Kantian maxim that punishment never be inflicted solely as a means to an extrinsic end: order, vengeance regulation, and so forth. (198)

2. The "Unfair Advantage" Thesis

A prominent philosophical variant of retributivism, the "unfair advantage" or "benefits-and-burdens" thesis, (199) justifies retribution by positing a quasi-contractual relationship between individuals in a society. On this view, punishment is "a debt owed to the law-abiding members of one's community; and, once paid, it allows re-entry into the community of good citizens on equal status." (200) Herbert Morris explains punishment similarly: The criminal law specifies rules of conduct that benefit all members of a society while imposing a corresponding burden of "self-restraint" on each; (201) when a person violates those rules, "he has something others have--the benefits of the system--but by renouncing what others have assumed, the burdens of self-restraint, he has acquired an unfair advantage.... Justice--that is, punishing such individuals--restores the equilibrium of benefits and burdens by taking from the individual what he owes, that is, exacting a debt." (202)

These contractual models of retributive punishment, as the exaction of a debt owed to society, also make little sense in the ICL context. In the first place, it would be bizarre to conceptualize the genocidaire as a free-rider on the hypothetical social contract of others not to destroy national, ethnic, racial, or religious groups, (203) or to regard a serious human rights abuser as arrogating to himself a benefit that others voluntarily relinquished in their common interest. (204) An economic view of criminal justice as redistributing benefits and burdens does not comport with our conception of crimes of extraordinary brutality. Furthermore, conceptualizing the war criminal or genocidaire as a deviant from social norms may make little sense where the criminal conduct would be more accurately described as conforming to a norm that prevails within the criminal's literal community, be it national, ethnic, racial, or martial. (205)

Finally, the circumstances of widespread ICL violations frequently involve the state not as the societal entity ensuring a just distribution of benefits and burdens, but on the contrary, as a prime force disrupting that distribution. The state, which in national criminal justice systems would be conceived, on the retributivist view, as the obligee to which the criminal owes a societal debt, emerges in the ICL context as an entity that may well share culpability for the crime--for international crimes characteristically require the collective cloak of authority that only the state or cognate entities (for example, tribal authorities or paramilitaries) can confer on individuals. The paradigm of retribution as a mechanism for restoring the balance of benefits and burdens between society and its members therefore seems utterly misplaced as applied to ICL crimes. To punish an individual perpetrator does not redistribute benefits and burdens or avert blood feuds threatened by unharnessed cycles of retaliatory vengeance, enabling a balancing of the communal scales or the maintenance of order within a nation-state. In fact, as the Serbian reaction to Milosevic's trial by the ICTY suggests, international criminal trials may well increase local dissonance and societal resentment within implicated nation-states and local communities, at least in the short term. The community that authorizes punishment, in short, might not be the one to which the purported societal debt is owed.

Retribution therefore emerges as a problematic justification for ICL punishment in large part because it presupposes both a coherent community and a relatively stable sociopolitical or legal order characterized by shared values. The circumstances that enable widespread violations of international humanitarian law and human rights atrocities generally involve the breakdown of precisely that order. "Where no civil law is," Hobbes wrote, "there is no crime." (206)

C. Expressive Proportionality

The retributive paradigm also seems misplaced in the ICL context because it apparently offers little guidance on proportionality. In a talionic sense, of course, no punishment can fit the most horrendous international crimes: slaughter of innocent civilians, systematic rape as a tool of war or genocide, and so forth. At the same time, the circumstances of extraordinary crime strain our intuitions about desert. Consider the well-known case of Drazen Erdemovic: What punishment, if any, befits a soldier who chose under duress, a threat to his own life, to participate in the summary execution of hundreds of Muslim civilians? (207) (Tellingly, the jurisprudential debate in Erdemovic focused less on speculation about deterrence--both the plurality and the dissent agreed that their decisions would be unlikely to affect the behavior of persons confronted with like circumstances in future conflicts--than on the proper message to be expressed by the sentence.) This case, while unique in the overt manner in which it highlights moral and legal issues that ordinarily remain obscured by the sheer brutality of the crimes, raises questions about the extent to which the criminal law can realistically regulate brutal violence in circumstances where crime becomes, to some degree, normative. (208) For purposes of proportionality, the gravity of the harm caused by an ICL violation seldom offers a particularly helpful metric; rather, context, "the individual circumstances of the convicted person," (209) is crucial.

International human rights law implicitly adopts the key Kantian principles that animate modern retributive theories: first, that punishment, while it may also serve broader social goals, must never regard the punished instrumentally in the first instance, as a mere means to an end; and second, that culpability is at least a necessary, if not a sufficient, condition for punishment. (210) It therefore forbids, for example, exemplary justice, even if that would better serve other legitimate penal objectives of the international criminal justice system, such as deterrence. These principles impose constraints on both the absolute and relative severity of punishment, cardinal and ordinal proportionality. Of course, given the nature of the crimes at issue, efforts to calibrate crime and punishment according to the lex talionis principle would apparently require punishments that contemporary international human rights law prohibits. (211) What Beccaria wrote in relation to capital punishment seems apt here: "If the passions, or the necessity of war, have taught men to shed the blood of their fellow creatures, the laws, which are intended to moderate the ferocity of mankind, should not increase it by examples of barbarity...." (212) ICL should be shaped, insofar as possible, to reinforce the core norms that it shares with international human rights law. Retributivism of the lex talionis variety has no place in this body of law.

But the expressive dimensions of retributivism nonetheless offer proportionality guidance. Few contemporary retributivists defend a lex talionis conception of proportionality. Andrew von Hirsch, for example, offers a retributive conception of ordinal proportionality that is parasitic on the expressive function of punishment. (213) It does not posit an a priori notion of the right penalty for different crimes, by reference to lex talionis or otherwise; it requires only that more culpable crimes be more severely punished. While a coherent ICL sentencing scheme requires some account of cardinal proportionality, the question how to assign a baseline, an anchor against which ICL crimes can be hierarchically ordered, seems less vital to the enterprise. The arbitrary establishment, but consistent application, of cardinal guidelines may be the best we can expect. It would be absurd to suppose that any particular term of years represents the correct penalty for, say, grave breaches of the Geneva Conventions.

One coherent, legitimate, and feasible basis for ordinal proportionality in international sentencing, however, is expressive: Punishments should convey the right degree of international condemnation relative to other defendants within the jurisdiction of the relevant tribunal. To maintain its legitimacy, an international tribunal must express censure, disapproval, and condemnation equally across disparate local circumstances. Genocide should not be punished more or less severely in Rwanda than in the former Yugoslavia. This is emphatically not to say that every conviction for genocide merits a sentence of equal length. The expressive value of a sentence--its legitimacy and authority--depends on the extent to which it both embodies the moral and legal norms of the authorizing community and fits the circumstances of the offender in light of those norms.

Emphasizing the expressive function of punishment in the context of ICL would enable tribunals to begin to address proportionality in a non-arbitrary way. No punishment, from a crude talionic perspective, can fit serious human tights atrocities, and any effort to rationalize ordinal proportionality on this basis would be doomed to futility. But from an expressive perspective, we can make rational judgments of proportionality consistent with a plausible concept of justice: "What justice demands is that the condemnatory aspect of the punishment suit the crime.... [T]he degree of disapproval expressed by the punishment should 'fit' the crime only in the unproblematic sense that the more serious crimes should receive stronger disapproval than the less serious ones...." (214)

Where, in an international context, criminal conduct becomes normative, crimes by rank-and-file perpetrators should generally not be deemed as blameworthy as those by the elites responsible for creating the normative conditions conducive to those crimes. By reference to international penal interests, for example, Dusko Tadir's harms obviously pale in comparison with those of, say, Radovan Karadzic or Ratko Mladic. By embracing an expressive account of proportionality and reorienting the metric of retributivism to the penal interests of the international community, we can begin to calibrate crime and punishment in ICL sentencing in a non-arbitrary fashion notwithstanding that, emotively, virtually all of the relevant crimes seem to demand the harshest penalties. For retribution, as for deterrence, the principal value of ICL punishment therefore lies in its expressive dimensions. (215) As the Appeals Chamber of the ICTY tightly emphasized, retribution in ICL "is not to be understood as fulfilling a desire for revenge but as duly expressing the outrage of the international community at these crimes." (216)

D. Audience and Expressive Clarity

Critiques of expressivism in international criminal justice focus on the potential distortion of the message. (217) What does even a comparatively long prison term for genocide communicate to a victim if the otherwise applicable national system would prescribe death for the same or an analogous crime? And how well do the channels for punitive communication work between international and national fora? (218) The expressive dimensions of punishment depend on its ability to convey the right meaning against the background of particular social norms, (219) which vary significantly between the states, societies, cultures, and other constituencies that comprise the international community. In part, the strong cross-cultural consensus that incarceration expresses condemnation mitigates this problem. But the force of this objection, in my judgment, counsels greater attention to communication and public education strategies in ICL, a focus on making the ICL sentencing process more effectively express the extraordinarily high level of international condemnation of ICL crimes. Below, I suggest some potential steps that the ICC, for example, might take in this direction.

Yet the effective communication that matters in the expressivist view is not only that contained in the message to the convicted person or a potential future criminal. Expressivism, echoing Durkheim, focuses in part on the value of punishment to the community itself, (220) in this case the figurative international community. "The intended audience of such exhortations is not just the wrongdoer of most concern to deterrence and retributive theorists. It is also the Everyone of most interest to expressive theorists: the law-abider and the lawmaker, the activist and the private citizen, and even the potential victim, today and tomorrow." (221) The expressive function of punishment serves the communicator, not only the recipient of the punishment or the rogue states or tyrannical leaders to whom it may convey a message. Like-minded law-abiding states and citizens--for example, those comprising the assembly of states parties to the ICC--benefit from the affirmation of a common commitment to international human rights norms and the rule of law, and the sentencing process contributes to the formation of consensus on the propriety and meaning of different punishments. (222) Over time, punishment by international criminal tribunals can shape as well as express social norms. And the international sentencing process can reinforce and vindicate those norms even if it cannot, alone, realistically be expected to deter or fulfill retributive aspirations held by each affected local constituency.

E. Rehabilitation: Literal Societal and Theological

International human rights law, as noted, emphasizes rehabilitation as the paramount goal of punishment. Few, of course, expect war criminals to repent after serving their sentences and return to duty as model soldiers, or megalomaniacal elites to see the error of their ways and become benevolent dictators or benign elected officials in the future. Nor do many worry about recidivism, for "the likelihood of persons convicted [by international criminal tribunals] ever again being faced with an opportunity to commit war crimes, crimes against humanity, genocide or grave breaches is so remote as to render its consideration in this way unreasonable and unfair." (223) Relative to ICL, rehabilitation, conceived in crime-control rather than humanistic terms, seems an inapposite goal. Perhaps for that reason, for all its prominence in international human rights law, it seldom receives attention in judicial judgments or scholarly analyses of the goals of international sentencing. (224) In an early judgment, the ICTY said that "it would seem that the particularities of crimes falling within the jurisdiction of the International Tribunal rule out consideration of the rehabilitative function of punishment." (225)

The ICTY has since recognized rehabilitation as a potential objective of ICL punishment but described it in quasi-religious terms redolent of Martin Buber: (226) "[T]he process of coming face-to-face with the statements of victims, if not the victims themselves, can inspire--if not reawaken--tolerance and understanding of 'the other,' thereby making it less likely that if given an opportunity to act in a discriminatory manner again, an accused would do so. Reconciliation and peace would thereby be promoted." (227) As this passage makes clear, the idea of rehabilitation encompasses several distinct goals, some more relevant to, or practicable for, ICL sentencing than others.

Rehabilitation traditionally implied a social vision of the criminal as metaphorically if not literally sick and therefore in need of treatment. This medical model fell out of favor in the 1970s and 1980s, in large part, philosophically, because of its perceived denial of autonomy and moral agency, and practically, because of its perceived failure. (228) Rehabilitation of the medical model variety finds virtually no expression or support in the judgments of the ad hoc tribunals. Given the body of literature emphasizing the need to appreciate that psychosocial circumstances cause or contribute to collective crimes of extraordinary hatred and violence, this omission seems odd, even ironic. Many rank-and-file perpetrators of ICL crimes, on this view, should be conceived not as inherently evil but as average, all-too-human individuals who fell victim to manipulation by elites, rendering them metaphorically sick with irrational fear, nationalist passion, or hatred. Many Bosnian Serbs, for example, were indoctrinated to believe that their Muslim neighbors, with foreign help, were poised to wage an imminent jihad against them and thus saw their crimes against Bosnian Muslims as self-defense. Plausibly, under ordinary circumstances, they would not have been inclined to commit crimes, let alone war crimes or crimes against humanity.

Today, the ICC faces the question of how to deal justly with rebel soldiers of the LRA abducted as children and indoctrinated through example and extraordinarily brutal conditioning, which over time desensitized them and made them willing participants in terrible crimes, including mutilation, rape, mass killing of civilians, and other ICL crimes. From a retributive perspective, it defies our intuitions to assert that children in circumstances like these deserve punishment; from a deterrent perspective, it would be absurd to suppose that children abducted and indoctrinated by violent conditioning can be significantly, if at all, deterred by the remote threat of prosecution. Nor will deterrence as a project of gradual norm penetration make a difference in this context; the normative universe in which children abducted by the LRA reach the age of criminal responsibility (eighteen, according to international law) destroys any habitual inhibitions against violence.

Realistically, the Prosecutor would be unlikely to go forward in these circumstances. (229) But child soldiers of the LRA highlight the problematic nature of moral responsibility in the ICL context. (230) Arguably, some rank-and-file participants in serious international crimes can to some degree be likened to this extreme case--hence the recurrent emphasis in the critical literature on social psychology and collective responsibility issues. On the one hand, as emphasized, it would be a mistake to assimilate all war criminals to this vision. But it would be just as mistaken to ignore the extent to which history and research show that "acts of exceptional cruelty can indeed be committed by 'ordinary people' under special circumstances." (231) We have no reason to think, to take a hyperbolic case, that someone guilty of summary executions in the context of a brutal civil war, with atrocities committed on all sides, would be a serial killer in a relatively stable, peacetime society. Some low-level perpetrators may be suitable candidates for rehabilitation, and it would be contrary to the spirit if not the letter of international human rights law to refuse to consider mitigation in such cases. Undoubtedly, rehabilitative considerations will in some cases conflict with the retributive penal interests of the victims. Where such conflicts exist, justice and the proper scope of international penal interests, including the synergy between ICL and international human rights norms, should prevail. The extent to which collective psychosocial factors should be deemed to mitigate culpability can be--and, I believe, should be--addressed at the sentencing stage, where considerations of factual guilt no longer impair a more searching inquiry into the relative culpability of particular defendants acting under diverse circumstances.

Rehabilitation in this literal sense, however, has received far less attention than the idea, again based on a questionable analogy, that international criminal justice can contribute to the figurative "rehabilitation" of communities riven by ethnic strife, war, a history of human rights atrocities, and so forth. (232) Many see this potential goal as a function of the individuation of guilt ostensibly fostered by ICL: "Blame should not rest on an entire nation but should be assigned to individual perpetrators of crimes and the responsible leaders." (233) To punish individuals, on this view, can absolve others as well as the collective society from which they originate, enabling its reintegration into the figurative international community--as, for example, when the United Nations welcomed Yugoslavia back after its surrender of Milosevic to the ICTY.

Unfortunately, these views rest on questionable "theological and medical models" that have "solidified into articles of faith" rather than experience or research. (234) Studies of the effect of the Nuremberg trials on postwar Germans, for example, remain inconclusive at best, (235) and scant evidence suggests that this project of collective absolution has worked in either Bosnia or Rwanda. In fact, in Serbia, reports indicate that the prosecution of Milosevic, far from delegitimizing him, has been perceived as a reflection of international persecution of Serbs, emboldening Serbian nationalists. Within states, as the South African experience shows, truth commissions may well be more effective at achieving collective rehabilitation. ICL, at least as applied by international tribunals, is not particularly well-tooled to pursue societal rehabilitation.

Furthermore, as several scholars emphasize, the liberal presumption against collective guilt biases us against and obscures the almost invariable collective element of ICL crimes, which casts doubt on a criminal law paradigm that hermetically separates the guilty from the innocent. At times, the state or another collective entity does bear blame or responsibility, even if the relative culpability of different actors that comprise that collective entity differs dramatically--from the passive acquiescence of the bystander to the (reluctant or enthusiastic) participation of the rank-and-file perpetrator to the deliberate incitement of the demagogue. (236)

Above all, perhaps, we should recognize that while aspirations about reconciliation and national healing may at times be laudable by-products of international criminal justice, they do not count as self-sufficient reasons to sentence a particular perpetrator more or less severely. Similarly, we can debate the plausibility, validity, or propriety of the Security Council's assertion that establishing the ad hoc tribunals will contribute to the restoration of international peace and security. But it would be odd, if not inappropriate, to sentence someone to more or less time in prison based solely on this aspiration. The Rome Statute expresses these goals in its preamble but rightly, in my view, says nothing about them in its provisions on sentencing.


If the principal value served by ICL punishment is expressive, what implications does this have for the substance and process of sentencing by international criminal tribunals? I would suggest three: First and foremost, distinct sentencing hearings, which the ICTY abandoned for expedience, should be reinstituted by the ICC and made an essential stage in the process of international criminal justice, not an "afterthought." (237) Second, the ICC and ICL jurisprudence generally should develop--not rigid sentencing guidelines of the kind brought into disrepute by the federal Sentencing Reform Act (238)--but a rational (if flexible) scheme to convey aggravating and mitigating factors, which should take into account the defendant's individual circumstances and role relative to the state, military unit, or other collective entity implicated by the crimes of conviction. Finally, international criminal tribunals should work to enhance the expressive potential of sentencing by ensuring the widespread publication and dissemination of judgments to the broadest possible audience and by maximizing the level of cooperation and jurisprudential exchange between national and international criminal justice institutions.

Sentencing, in international no less than national criminal law, should be "a ritual of manifest moral significance." (239) Indeed, the formal expression of communal condemnation assumes dramatic importance in ICL, where the standard justifications for and goals ostensibly served by criminal punishment--deterrence, retribution, rehabilitation, and incapacitation--seem less plausible, legitimate or efficacious. Yet after a few early experiments with holding a distinct sentencing phase, (240) the ad hoc tribunals abandoned this procedure by amendments to their internal rules, apparently based on considerations of expedience and cost, (241) and perhaps also on the unfamiliarity of sentencing hearings to international judges from civil law states. Instead, the tribunals now typically append their sentencing determinations to voluminous written judgments, rendering them relatively obscure and inaccessible to the public and largely eviscerating their distinctive symbolic significance. Furthermore, because the tribunals tend to issue a single sentence intended to cover the "totality of an accused's conduct," it becomes "difficult to determine the range of sentences for each specific crime." (242) This is unfortunate, for "transactional" sentencing of this sort, (243) however expedient, impedes the growth of a mature sentencing jurisprudence that could provide guidance to national courts, where, because of the principle of complementarity and resource and other constraints, the bulk of future ICL prosecutions will be held.

The expressive functions of punishment--its potential to indicate authoritative disavowal of criminal conduct, signify non-acquiescence in the crimes, vindicate international norms, and (perhaps) absolve ethnic or national communities, as collectives, of guilt by inculpating individuals--depend on communication. (244) Sentences issued only in writing, tacked on to dense, lengthy judicial decisions and unaccompanied by a public "ritual of manifest moral significance" that expresses the reprobative judgments of the relevant community, cannot fulfill these functions very effectively. The application of ICL by international criminal tribunals will almost certainly remain in large measure a symbolic exercise. Given resource and political constraints, the ad hoc tribunals, the ICC, and future international tribunals will never be able to function as a self-sufficient criminal justice system; they will never be able to try more than a fraction of the perpetrators. (245) It is the symbolic value--not the number--of convictions that matters most to the goals that sentencing by these tribunals can realistically be expected to fulfill.

Of course, given the gravity of most ICL crimes, juxtaposed against the constraints on the kind and degree of punishment imposed by international human rights law, one might reasonably question the ability of any sentence of incarceration to "duly express[] the outrage of the international community at [ICL] crimes." (246) In part, this problem is insoluble: The normative goals of international human rights law impair the ability of punishment to accurately express the extraordinary global condemnation, anger, and retributive sentiments that these crimes elicit, particularly where the punitive norms of affected local communities would indicate a more severe penalty. The expressive value of punishment may, however, be enhanced not only by substantive changes in the severity of punishment but by considering how more effectively to make the "process the punishment," (247) particularly for the elites on which the ICC intends to focus. A sentencing hearing would enable experimentation in this regard.

What would such a hearing involve? In bare outline, both the defense and the prosecution should surely be given an opportunity to make formal submissions with relevant mitigating and aggravating circumstances, including, where appropriate, psychological and other expert testimony. (248) Furthermore, tribunals should consider adopting the familiar practice of having an independent official prepare a presentencing report, which would explore, as the Rome Statute instructs, "the individual circumstances of the convicted person." (249) Because of the collective nature of ICL crimes, and the often dramatically different normative universe in which the perpetrators act, developing a sentencing process and jurisprudence that distinguishes different categories of defendants based on their status, role, and background seems not only appropriate but essential to the legitimacy of the enterprise. (250) And despite the bad press generated by the (until recently, mandatory) federal sentencing guidelines, the adoption of genuine sentencing guidelines by international tribunals would be a significant step toward rationalizing the sentencing process, particularly in cases of multiple convictions. (251) Finally, a focus on the expressive value of punishment counsels public pronouncement of the sentence, perhaps even of the hearing itself, disseminated to as broad an audience as possible. (252)

The Rome Statute offers a unique opportunity to refocus attention on the significance of sentencing to the goals of ICL. Like its predecessor instruments, it says little about sentencing. But the positive-law framework created by the statute lends itself to a judicial interpretive process that could more effectively serve the expressive dimensions of punishment. Article 77 authorizes the Court to impose a specified term of imprisonment not to exceed thirty years except where a life sentence is "justified by the extreme gravity of the crime and the individual circumstances of the convicted person." (253) Article 78 instructs the Court to determine sentences by taking "into account such factors as the gravity of the crime and the individual circumstances of the convicted person." (254) Rule 145 of the draft Rules of Procedure and Evidence, however, goes beyond the minimal provisions of the ICTY and ICTR statutes, enumerating with greater specificity relevant aggravating and mitigating factors, including:
   the harm caused to the victims and their families, the nature of
   the unlawful behaviour and the means employed to execute the
   crime; the degree of participation of the convicted person; the
   degree of intent; the circumstances of manner, time and
   location; and the age, education, social and economic condition
   of the convicted person. (255)

This emphasis on context, role, and circumstances is further reinforced by the inclusion, as one of two explicit mitigating factors, of "circumstances falling short of constituting grounds for exclusion of criminal responsibility, such as substantially diminished mental capacity or duress." (256) Together, these provisions offer a positive-law framework that can be construed to recognize the potential mitigating role of context and the collective nature of ICL crimes for rank-and-file perpetrators "who allowed themselves to be drawn into a maelstrom of violence, even reluctantly." (257) Rule 145(2)(b), conversely, can be construed to address those "who initiated or aggravated" the "maelstrom of violence," (258) an aggravating factor reflected in the sentencing jurisprudence of the ad hoc tribunals and now codified in the Rome Statute as "[a]buse of power or official capacity." (259) This construction also has the virtue of offering some guidance in interpreting Article 78's authorization of life imprisonment "when justified by the extreme gravity of the crime and the individual circumstances of the convicted person," (260) for Rule 145(3) speaks of the conditions for a life sentence being "evidenced by the existence of one or more aggravating circumstances." (261)

Most significantly, the Rome Statute, unlike its predecessors, presumptively "establishes the principle of a distinct sentencing phase." (262) This represents a significant innovation not only because of its capacity to enhance the expressive value of ICL, but also because, as in the national context, the "failure to hold a separate sentencing hearing may put the accused at a real disadvantage during the trial." (263) Of course, international criminal tribunals do not confront these issues in the constitutional context of the Sixth Amendment right to trial by jury. But similar due process tensions exist: A defendant may, for example, wish to introduce evidence in mitigation but hesitate to relinquish the right to remain silent and the privilege against self-incrimination. (264) The absence of a distinct sentencing stage in ICL may also threaten to compromise judicial neutrality, for evidence relevant only to sentencing--often of a highly inflammatory nature--must then be introduced at trial, where it may interfere with even the most professional judge's ability to weigh the evidence relevant only to guilt or innocence dispassionately. (265) The recent proliferation of guilty pleas before international tribunals makes a distinct sentencing phase all the more crucial.

From a long-term perspective, a focus on the expressive capacity of punishment counsels greater attention to how law-abiding states and citizens, not only rogue states and the punished, perceive sentencing in international criminal law. The adoption of the Rome Statute itself prompted a number of states "to incorporate prohibitions on genocide, war crimes, and crimes against humanity into their criminal statutes," lest the ICC "find them 'unable' to prosecute international crimes." (266) ICC sentencing judgments, like the statute itself, hold a similar potential to influence the practice and policy of states by acting as an engine of jurisprudential and normative development where it matters the most, within nation-states. (267)

Any account of international sentencing must be realistic about its ability to achieve the ambitious and diverse goals ascribed to it. But far from being "of secondary importance in the overall scheme of international justice," (268) as it has historically been treated, sentencing is as vital to the values and goals of ICL as adjudication As the ICC begins to investigate and prosecute its first cases, it should bear in mind that the Rome Statute's explicit provision for sentencing hearings offers an opportunity to reinvigorate and jurisprudentially develop the law and process of ICL sentencing, an overdue imperative. The beginnings of a "common law" of ICL sentencing, based on the judgments of the ad hoc tribunals and, to a lesser extent, hybrid and national courts applying ICL, provide a foundation on which to build. International criminal tribunals must develop coherent, fair, and principled sentencing practices, for their long-term success depends in part on the extent to which the social institution of punishment can be shaped to reflect, pursue, and in time, one hopes, justify their substantial costs.

(36) The Statute of the ICTR limits punishment to imprisonment. ICTR Statute, supra note 4, art. 23(1). Rwandan law authorizes the death penalty. Because the ICTR enjoys jurisdictional primacy over Rwandan courts, id., art. 8(2), and has sought to prosecute the most culpable offenders, as a practical matter, the leaders, orchestrators, and architects of the genocide will not face the death penalty, while rank-and-file perpetrators, who have been relegated to Rwanda's local courts, will.

The highly political nature of ICL prosecutions--that only some serious international atrocities (and only some of the perpetrators of those atrocities) have been or will be prosecuted because of the realities of international power and politics--is a valid objection as far as it goes to the international criminal justice system as a whole. See id. at 116 ("A random confluence of political concerns produced ad hoe tribunals for just two out of a number of conflicts that warranted such treatment."); see also Drumbl, supra note 4, at 581. But given that the system exists, efforts to bring greater coherence, justice, and due process to its operation remain valuable nonetheless, and in the long term, may render the political selectivity of the system less tolerable to its constituents.

(55) The priorities of these actors cannot, of course, be equated simply with any monolithic international community. Because the ICC will frequently operate "'in the midst of the conflict" rather than "after the acute and violent situation in which the alleged crimes occurred has been resolved by military victory or political settlement," Arsanjani & Reisman, supra note 35, at 385 (emphasis added), it may well generate conflict both within different sectors of the international community (for example, between political and judicial priorities), as well as between the international community and implicated local communities.

(56) In the context of Rwanda, for example, the existence of the ICTR has undoubtedly privileged international goals "over the desires of many of those who have been most immediately affected by the genocide." Alvarez, supra note 1, at 409-10. The ICC does not enjoy the jurisdictional primacy criticized by Alvarez. Yet once the Court takes jurisdiction of a case, it seems unrealistic to expect that the manifold international pressures on the Prosecutor and Court will not result in a similar pattern, for "international tribunals are accountable to, and respond most readily to, international lawyers' jurisprudential and other agendas and only incidentally to the needs of victims of mass atrocity." Id. at 410. I do not mean to suggest that the ICC, or any other international criminal tribunal, should neglect the interests of local communities harmed by the ICL violations, nor that the Prosecutor will not cooperate with national authorities both to accommodate (to some degree) the latter's penal interests and to maximize the efficiency of international justice. The Court has already worked with local authorities in the Democratic Republic of the Congo and Uganda, the sites of the first two situations it decided to investigate.

INT'L L. 69, 79 (2004) (noting that the "comfortable rhetoric" of an international community "disguises the fact that there is no unified 'world community' with a simple and easily accessible opinion to be had for the asking," but "only hundreds of societies, with diverse and conflicting national practices").

Extradition treaties tend to be bilateral, though regional multilateral treaties exist. E.g., European Convention on Extradition, Dec. 13, 1957, 359 U.N.T.S. 273.

(65) The Rome Statute includes aggression as a crime within the ICC's jurisdiction subject to the significant provisos that it must be defined satisfactorily and the conditions for its prosecution specified. Rome Statute, supra note 4, art. 5(1)(d), 5(2). A serious obstacle to defining aggression under international law is the uncertain relationship between the Security Council's political role in determining the existence of a threat to international peace and security and a putative international criminal tribunal's legal role in determining guilt for the initiation of aggressive war. See Military and Paramilitary Activities in and Against Nicaragua (Niear. v. U.S.), 1986 I.C.J. 14, 290 (June 27) (Sehwebel, J., dissenting) (emphasizing that "while the Security Council is invested by the Charter with the authority to determine the existence of an act of aggression, it does not act as a court in making such a determination"; rather, "[i]t may arrive at a determination of aggression--or, as more often is the case, fail to arrive at a determination of aggression--for political rather than legal reasons").

The assertion that widespread or systematic ICL violations can constitute a threat to international peace and security sufficient to justify action by the Security Council under Chapter VII of the U.N. Charter, while subject to skepticism in some quarters, cf Prosecutor v. Tadic, Case No. IT-94-1-AR72, Decision on Defence Motion for Interlocutory Appeal on Jurisdiction, [paragraph] 27 (Oct. 2, 1995), 35 I.L.M. 32, 42 (1996) (rejecting jurisdictional challenge based on the argument "that the establishment of the International Tribunal had neither promoted, nor was capable of promoting, international peace, as the current situation in the former Yugoslavia demonstrates"), is not implausible. The collateral consequences of large-scale human rights atrocities include "cross-border violence, substantial refugees flows, serious regional instability, or appreciable harm to the nationals of another state." Michael J. Matheson, United Nations Governance of Post-Conflict Societies, 95 AM. J. INT'L L. 76, 83 (2001); see also Akhavan, Justice in the Hague, supra note 11, at 740. Consider, for example, the aftermath of the Rwandan genocide, which led thousands of Hutu genocidaires-cum-refugees to seek sanctuary in the state then known as Zaire, ultimately precipitating the demise of the Mobutu regime and contributing to, if not causing, what has been characterized as a virtual world war in central Africa. Is it coincidental that one of the first situations being investigated by the ICC is in the same state, now known as the Democratic Republic of Congo?

(70) Victims, in both national criminal law and ICL, may be, and ideally should be, beneficiaries of the criminal law. International tribunals should take steps to improve their solicitude for the victims and to enhance their legitimacy in the eyes of local communities. But criminal law, national and international alike, does not and should not function principally as a proxy for the victim's desire for talionic vengeance. This is not to suggest that ICL need not concern itself with the needs of victims; it is only to say that the failure of ICL tribunals to respond perfectly to the desires of the community victimized by ICL and the related tensions that inevitably result do not condemn the enterprise.

(71) Policy Paper, supra note 50, at 4.

(72) See Danner, supra note 1, at 441-42 & n.105. Disparity will almost certainly remain an issue in a different sense: Under the ICC complementarity regime, whether a perpetrator faces national or international justice, and therefore the sentence to which he may be exposed, may depend on a variable unreiated to culpability, the ability and willingness of national authorities to prosecute. But in that event, the penal interests at stake remain national in the first instance. The perpetrator cannot complain if his sentence would have been lower under international law, any more than perpetrators of national crimes can justly complain that the sentence they would have received in another state with concurrent jurisdiction over the same crime would have been less severe.

(73) See Dickinson, supra note 57, at 310. But see Arsanjani & Reisman, supra note 35, at 402 (noting that the hybrid courts for Sierra Leone and Cambodia, which were to be funded by voluntary contributions, face severe funding problems that call into question the viability of this model).

(75) The Rome Statute says little about sentencing, see supra note 4, arts. 76-78, but broadly, it adopts harm ("gravity of the crime") and culpability ("individual circumstances of the convicted person") as the determinants of sentences. Id., at art. 78, [paragraph] 1.

(76) Fletcher, supra note 11, at 1514-25.

(77) In my view, to use Fletcher's examples, a lone soldier, acting without the explicit or tacit approval of his superiors, who refuses quarter to enemy soldiers would be guilty of a war crime despite the absence of collective authorization, see id. at 1521; and a Sinophobe in Connecticut who kills the first two Chinese men he encounters, with intent to destroy the Chinese people at least in part, would be technically guilty of genocide despite the idiosyncratic nature of his crime in context. Id. at 1523. The mens rea for genocide, unlike that for crimes against humanity, does not require knowledge of "a widespread or systematic attack." Cf. Prosecutor v. Ndindabahizi, Case No. ICTR-2001-71 [paragraph] 471 (July 15, 2004) (killing of a single individual with the requisite intent constitutes genocide). Equally, for war crimes (to use a current example), it seems clear that an American soldier in Iraq who tortures a prisoner at Abu Ghraib is guilty of a violation of the Geneva Conventions whether he acts as a "bad apple" or pursuant to an official policy promulgated at some level of the military or civilian hierarchy.

(78) But see Danner, supra note 1, at 472 n.238 (stating that "war crimes may often be committed by soldiers acting on their own rather than according to a larger policy," and that "the chapeau of the war crimes provisions in both Statutes [the ICTR and ICTY Statutes] require neither an illegal collective action nor an act targeted at someone because of his affiliation with a group").

(92) Prosecutor v. Tadic, Case No. IT-94-1, Judgment in Sentencing Appeals (Jan. 26, 2000) (separate opinion of Cassese, J.). The jurisprudence of the ad hoc tribunals has engendered a debate over whether, all other circumstances being held constant, a crime against humanity should be deemed more serious than war crime, or an act of genocide more serious than a crime against humanity. Compare, e.g., Prosecutor v. Erdemovid, Case No. IT-96-22, [paragraph] 26 (Oct. 7, 1997) (McDonald and Vohrah, JJ., joint separate opinion) (invalidating Erdemovid's guilty plea in part because neither defense counsel nor the Trial Chamber "had explained to [him] that a crime against humanity is a more serious crime [than a war crime] and that if he had pleaded guilty to the alternative charge of a war crime he could expect a correspondingly lighter punishment"), and Prosecutor v. Kambanda, Case No. ICTR-97-23-S, [paragraph] 14 (Sept. 4, 1998) (expressing "no doubt" that "violations of Article 3 common to the Geneva Conventions and of the Additional Protocol II thereto ... are considered as lesser crimes than genocide or crimes against humanity"), with Prosecutor v. Tadic, supra, [paragraph] 69 ("[T]here is in law no distinction between the seriousness of a crime against humanity and that of a war crime."). The latter position has prevailed in the ICTY, though several jurists continue to dissent from it. E.g., Prosecutor v. Furundzij a, Case No. IT-95-17/1-T, July 21, 2000 (declaration of Vohrah, J.).

(96) Rome Statute, art. 78, [paragraph] 1.

(97) See Danner, supra note 1, at 470 n.228; see also Fletcher, supra note 11, at 1511-12 ("Criminal organizations pose a heightened danger in their collective interdependence and reciprocal support, a danger that exceeds the aggregative threat of the individuals constituting a conspiracy.").

(98) While it would be misguided to assert categorically that elites always deserve more punishment than subordinates, "the degree of responsibility generally increases as we draw further away from the man who uses the fatal instrument with his own hands and reach the higher levels of command." Attorney-General v. Eichmann, 36 I.L.R. 11, 237 (Isr. Sup. Ct. 1968). The sentencing jurisprudence of the ad hoe tribunals for the former Yugoslavia and Rwanda recognizes this aggravating circumstance under the rubric of abuse of power, authority or trust. E.g., Prosecutor v. Kambanda, Case No. ICTR-97-23-S, Judgment and Sentence, [paragraph] 44 (Sept. 4, 1998) ("Abuse of positions of authority or trust is generally considered an aggravating factor."); Prosecutor v. Krstic, Case No. IT-98-33, [paragraph] 709 (Aug. 2, 2001) (emphasizing that "a person who abuses or wrongly exercises power deserves a harsher sentence than an individual acting on his or her own, for "[t]he consequences of a person's acts are necessarily more serious if he is at the apex of a military or political hierarchy and uses his position to commit crimes").

(109) Id. at 1143 (arguing that criminal responsibility can be reconciled with determinism by defining responsibility, as G.E. Moore did, to require only "the freedom (or power) to give effect to one's own desires," that "[o]ne's choices, or willings ... themselves be causes of actions," but not "that such choices be uncansed" by extrinsic factors) (citing G.E. MOORE, ETHICS 84-95 (1912)). But see Isaiah Berlin, Historical Inevitability, in LIBERTY 94, 116 n.1 (Henry Hardy ed. 2002) (1969) (criticizing a similar conception of freedom). The syllogism also relies on peculiarly modern sensibilities about free will, desert, and moral responsibility. See FRIEDRICH NIETZSCHE, ON THE GENEALOGY OF MORALITY 39 (Maudemarie Clark & Alan J. Swensen eds. & trans., 1998) (1887) ("The thought, now so cheap and apparently so natural, so unavoidable, a thought that has even had to serve as an explanation of how the feeling of justice came into being at all on earth--"the criminal has earned his punishment because he could have acted otherwise"--is in fact a sophisticated form of human judging and inferring that was attained extremely late; whoever shifts it to the beginning lays a hand on the psychology of older humanity in a particularly crude manner.").

(110) See HERBERT PACKER, THE LIMITS OF THE CRIMINAL SANCTION 74-75 (1968) ("The idea of free will in relation to conduct is not, in the legal system, a statement of fact, but rather a value preference having very little to do with the metaphysics of determinism and free will....

Very simply, the law treats man's conduct as autonomous and willed, not because it is, but because it is desirable to proceed as if it were."); see also Isaiah Berlin, Historical Inevitability, in LIBERTY, supra note 109, at 122-23 ("I do not here wish to say that determinism is necessarily false, only that we neither speak nor think as if it could be true, and that it is difficult, and perhaps beyond our normal powers, to conceive what our picture of the world would be if we seriously believed it; so that to speak, as some theorists of history (and scientists with a philosophical bent) tend to do, as if one might (in life and not only in the study) accept the determinist hypothesis, and yet continue to think and speak much as we do at present, is to breed intellectual confusion."). A purely utilitarian criminal justice model can justify punishment without denying strict determinism, for "[w]hether or not human acts are completely determined by prior causes, punishment can be an efficacious prior cause." Greenawalt, supra note 6, at 352-53. But few theorists (and even fewer laypersons) embrace such models, which remain subject to well-known objections.

The court concluded that despite "superficial similarities," Musema's case, unlike Serushago's, did not present "exceptional circumstances in mitigation," and "[c]onsequently, the circumstances of the two cases are not so similar to justify a claim that the Trial Chamber erred by imposing a disproportionate sentence in respect of Musema."

(145) Specific deterrence, punishment's tendency to prevent the person punished from himself engaging in future criminal conduct, has rightly been marginalized in the sentencing jurisprudence of the ad hoe tribunals, for "the likelihood of persons convicted here ever again being faced with an opportunity to commit war crimes, crimes against humanity, genocide or grave breaches is so remote as to render its consideration in this way unreasonable and unfair." Prosecutor v. Kunarac, Case No. IT-96-23-T & IT-96-23/l-T, [paragraph] 840 (Feb. 22,2001).

(146) Incapacitation, an extreme form of specific deterrence, seems equally inapposite. With the exception, perhaps, of some future Napoleon, few war criminals seem to pose a real danger of recidivism requiring incapacitation. By the time most orchestrators of serious human rights atrocities can be apprehended and prosecuted, they typically pose no future danger. Some may nonetheless deserve a life sentence, but not because of concerns about future dangerousness were they released after a finite term. On the other hand, indictment, investigation, and prosecution can disempower, discredit, and delegitimize tyrannical leaders, stigmatizing them as international fugitives, unable to travel freely, and at risk of having their assets frozen. Developments in the Law: International Criminal Law, 114 HARV. L. REV. 1943, 1962 & n.31 (2001). Milosevic's indictment, for example, arguably contributed to his political demise. Payam Akhavan, Beyond Impunity: Can International Criminal Justice Prevent Future Atrocities?, 95 AM. J. INT'L L. 7, 9 (2001) [hereinafter Akhavan, Beyond Impunity]. The saga of Pinochet's attempted prosecution by Spain under a theory of universal jurisdiction likewise seems to have lifted the veneer of political invulnerability that formerly prevented local efforts to bring him to justice. This quasi-incapacitative goal, however, is a political tool that precedes the trial process; or, following Hart, it may be understood as one justification for the establishment of an international criminal justice system but not, I think, as a consideration relevant to the distribution of punishment, that is, to sentencing.

To maximize the deterrent value of ICL, then, prosecutors probably should focus, as they increasingly have, on increasing the real risk of apprehension and prosecution for the elites who orchestrate ICL crimes rather than the rank and file mobilized to carry them out. Empirical studies validate a view expressed early on by Beccaria: "Crimes are more effectively prevented by the certainty than the severity of punishment." Cesare Beccaria, On Crimes and Punishments (1764), in READINGS IN JURISPRUDENCE AND LEGAL PHILOSOPHY 346, 349 (Morris R. Cohen & Felix S. Cohen eds., 1951); accord Prosecutor v. Furundzija, Case No. IT-95-17/1-T, [paragraph] 290 (Dec. 10, 1998) ("It is the infallibility of punishment, rather than the severity of the sanction, which is the tool for retribution, stigmatisation, and deterrence."). For an overview of the empirical work, see generally ANDREW VON HIRSCH, ET AL., CRIMINAL DETERRENCE AND SENTENCE SEVERITY: AN ANALYSIS OF RECENT RESEARCH (1999).

(169) BASS, supra note 3, at 294. From a pragmatic perspective, prosecuting elites, somewhat counter-intuitively, actually requires fewer resources relative to the breadth of the indictments than cases against low-level perpetrators, for the doctrine of command responsibility sweeps a wider evidentiary net, expands the limits of relevant evidence, and "[a]ccordingly, the temporal and geographical scope of evidence that may be invoked in support of prosecutions is very wide." Akhavan, Justice in the Hague, supra note 1 l, at 779.


(171) This is not, of course, to suggest that such figures cannot act rationally. Saddam Hussein acted rationally when he agreed to permit U.N. inspectors back into the country in the wake of a unanimously adopted Security Council resolution 1441. S.C. Res. 1441 (Nov. 8, 2002), 41 I.L.M. 250 (2003). Slobodan Milosevic acted rationally when he agreed to the Dayton Peace Accords. But the prospect of serving a sentence of incarceration for war crimes will be unlikely to enter into the rational calculations of such elites unless and until they believe that they may lose.

(194) I do not mean to imply the oft-criticized view that the Rwandan genocide reflected no more than the reemergence of historical or primordial ethnic animosity. Studies of the genocide uniformly reject this view and emphasize the extent to which elites manipulated and exacerbated latent ethnic tensions as a means to political power. See generally ALISON DESFORGES, LEAVE NONE TO TELL THE STORY (1999); PHILIP GOUREVITCH, WE WISH TO INFORM YOU THAT TOMORROW WE WILL BE KILLED WITH OUR FAMILIES (1998). Equally, most scholars reject the vision of the conflict in the former Yugoslavia as the inevitable explosion of latent ethnic tensions between Bosnian Muslims, Croats, and Serbs in the aftermath of the demise of Tito's iron-fisted rule.

(204) Retributive theories of the "unfair advantage" variety may offer a more coherent justification for punishment of war crimes. It makes some sense to conceive of the laws of war as a body of conduct agreed to by states for their mutual benefit. Violations, on this view, give rise to an imbalance of benefits and burdens, which punishment rectifies. Indeed, the laws of war historically recognized a practice redolent of this view, reprisals, whereby violations of the laws of war by one state gave rise to a reciprocal right of the other state to engage in otherwise prohibited wartime conduct. Punishment of individuals for war crimes might be conceived along similar lines as a means of restoring the balance of benefits and burdens disturbed by violations of rules established for the mutual benefit of combatants. In the modern era, however, this reciprocity rationale for the laws of war would strike many as at least partially anachronistic. International human rights law has reconceptualized international humanitarian law, in substantial part, as the human rights component of the laws of war, a body of standards designed to guarantee minimal levels of human dignity and decency even in times of systematic violence; hence modern international humanitarian law outlaws reprisals in all circumstances.

(215) Embracing an expressive function for ICL sentencing does not mean abandoning the side-constraint imposed by justice or "just deserts" theories: that individuals not be treated solely as a means to an extrinsic social end. To the contrary, the right to punish remains rooted in the acknowledgment of human beings as moral agents. Modulating the degree of punishment for expressive purposes--particularly once we recognize that no metaphysically correct term of incarceration corresponds to the gravity of the harm is not objectionable based on the Kantian maxim.

See Prosecutor v. Musema, Case No. ICTR-96-13-A, Appeals Chamber, [paragraphs] 382-83 (Nov. 16, 2001). The adjustments under the U.S. Federal Sentencing Guidelines for "organizer or leader," "manager or supervisor," "minor participant" and "minimal participant" would likely prove too crude for this purpose, but they suggest one plausible way to provide some structure to this dimension of ICL sentencing.

(256) Id. Rule 145(2)(a)(i). The other enumerated mitigating circumstance reflects concerns extrinsic to culpability, the "person's conduct after the [criminal] act, including any efforts by the person to compensate the victims and any co-operation with the Court.'" Id. Rule 145(2)(a)(ii).

(261) The ICTR alluded to these role-based aggravating and mitigating factors but, in my view, seriously misapplied them in a recent judgment. Elizaphan Ntakirutimana, a senior pastor at the Mugonero Complex, betrayed his parishioners, some of whom had actively sought his help during the genocide, by leading attackers to their hiding place, pointing out Tutsi refugees attempting to flee, and encouraging and inciting the attackers to kill them. While the Trial Chamber nominally emphasized "abuse of trust" as an aggravating factor, see Prosecutor v. Elizaphan Ntakirutimana, Case No. ICTR-96-10, [paragraphs] 900-04 (Feb. 21, 2003), it gave grossly undue weight to evidence that "Ntakirutimana was essentially a person of good moral character until the events of April to July 1994 during which he was swept along with many Rwandans into criminal conduct," id. [paragraph] 895, and therefore sentenced him to only ten years for genocide. Ntakirutimana, a mature and well-educated church elder who (as the evidence cited by the Trial Chamber makes clear) fully understood the wrongfulness of his conduct, see id., is hardly the kind of rank-and-file participant whose punishment should be mitigated because he found himself "swept along with many Rwandans," or as the Krstic court put it, because he "allowed [himself] to be drawn into a maelstrom of violence, even reluctantly." Prosecutor v. Krstic, Case No. IT-98-33, Judgment, [paragraph] 711 (Aug. 2, 2001).

(263) Id. at 981; cf Apprendi v. New Jersey, 530 U.S. 466, 557 (Breyer, J., dissenting) ("[T]o require jury consideration of all such factors--say, during trial where the issue is guilt or innocence--could easily place the defendant in the awkward (and conceivably unfair) position of having to deny he committed the crime yet offer proof about how he committed it.").

REV. 53, 69-73 (2001) (arguing that the introduction of evidence relevant only to sentencing at the trial of Radislav Krstic compromised the ICTY's perceived legitimacy).

(266) See ICC, Office of the Prosecutor, Paper on Some Policy Issues Before the Office of the Prosecutor 3 (Sept. 2003) ("The existence of the Court has already encouraged States to incorporate as domestic law the crimes within the jurisdiction of the Court."); see also Turner, supra note 38, at 8-9 & n.38 (also describing how Germany enacted domestic legislation to prosecute offenders in the wake of the First World War to avoid threats of an international tribunal). Sudan began, albeit likely in bad faith, to establish institutions for the domestic adjudication of ICL violations in the months culminating in referral of the situation of Darfur to the ICC.
