Self-help and the separation of powers.

III. THE UNITY OF SELF-HELP: SECOND-PARTY ENFORCEMENT IN LAW AND THEORY

"In many social contexts, self-help, when rendered promptly and in proper amounts, is one of the most indispensable and effective methods of social control."

--Robert C. Ellickson (212)

"Self-help may well be the first step toward anarchy."

--Idaho Supreme Court Justice Stephen Bistline (213)

We have seen that in the separation-of-powers field, self-help plays a vital, inescapable, and at times deeply troubling role. The same could be said of many fields of law: the basic dilemma posed by self-help is widespread, if not universal. Institutional and doctrinal designers have struggled for centuries to harness the benefits of second-party enforcement while keeping anarchy and abuse at bay, to mediate "the longstanding tension between the imperatives of an established system of laws and the individual needs and desires to avoid and remedy injury as effectively and efficiently as possible." (214)

This Part considers solutions that have emerged from this struggle. The goal is not to provide a satisfying account of all self-help law, but rather, and more modestly, to identify some common strategies and generalizable insights that might shed light on the interbranch context. I will focus on the international law doctrine of countermeasures, which allows states to take certain actions that would otherwise be unlawful in response to lawbreaking by another state. This doctrine offers not only the most similar case to the domestic separation of powers--it, too, regulates conflict among formally equal government institutions--but also the most reticulated body of rules on conditional self-help. In distilling these rules and connecting key principles to private law analogues, I hope primarily to facilitate analysis of U.S. constitutional practices. Much as Part II sought secondarily to advance the study of constitutional conventions, I hope also to contribute to the burgeoning literature on "self-help as a unified theme." (215)

A. The Dilemma of Self-Help

Self-help would not pose such a knotty problem for legal designers if it did not yield valuable benefits. But it does, sometimes. When individual actors are allowed to take unilateral measures to remedy the wrongdoing of others, in advance or in lieu of a mediated process, it may serve to deter such wrongdoing from occurring in the first place, reduce administrative costs, promote autonomy--or sovereignty-related values, and facilitate speedier redress. Less obviously, decreased reliance on third-party dispute resolution might serve to facilitate the maintenance of cooperative relations, mitigate feelings of alienation from the law, or generate deeper internalization of first-order legal norms. From any number of nonconsequentialist as well as consequentialist perspectives, self-help holds theoretical appeal. It certainly holds pretheoretical, atavis tic appeal. "Self-help of some kind has always been with us," (216) and so long as human (and institutional) nature remains fundamentally self-regarding and self-protective, it presumably always will.

Against these potential benefits, the normalization of self-help carries tremendous risks, especially in the case of conditional privileges to act in ways that otherwise would be unlawful. In taking it upon themselves to rectify the misdeeds of others, self-helpers effectively act as judges of their own cause. There is ample reason to worry that they will misconstrue the law along the way-not just, or even primarily, on account of bad faith, but on account of motivated cognition (217) and reliance on congenial interpretive methods or theories of law. (218) That is, self-help increases the likelihood not just of legally abusive remedial determinations but also of legally erroneous ones. In so doing, self-help may tend to exacerbate asymmetries of power between the parties, favoring "the strong over the weak." (219) Self-help can also generate negative spillovers, paradigmatically in the form of escalating cycles of recrimination, retaliation, and violence. These overlapping concerns, together with the potential shift in decisional authority away from the courts, are enough to menace most any conception of a well-ordered society. Like bounty hunters, self-help is a mechanism for enforcing law that contains the seeds of a greater lawlessness.

Importantly, this dilemma is not confined to legal regimes in which centralized enforcement is utterly lacking or radically defective. Quite the opposite. No regime depends entirely on third-party policing or adjudication to enforce its rules and administer remedies. To do so would be grossly inefficient, if not also incompatible with people's basic desires to defend themselves and to get even. It is "a ubiquitous, if underappreciated, feature of all legal systems, ancient and modern," that "heavy reliance" is placed "on the use of self-help to enforce legal commands" and to produce social control. (220) Constitutional law is no different, as has already been shown.

Still, one might wonder whether other regimes could have much meaningful to say about constitutional self-help. In most areas of domestic law, the exercise of conditional self-help is subject to potential judicial oversight. If I take it upon myself to redress a perceived breach of my contract or property rights--say, by deducting damages from what I owe a seller (221) or by trespassing to reclaim a personal chattel (222)--then a court may eventually be engaged to review the legality of my actions. In the separation-of-powers context, by contrast, the shadow of adjudication is fainter. Legal disputes are less apt to be justiciable. (223) Courts play a comparatively minor role in supervising self-help, whereas mechanisms like elections and public opinion play a much larger role. Actual violence, moreover, is not such a pressing concern. It is a convention of inter-branch practice, we might say, that feuding government officials refrain from physically attacking one another. (224) (This is another example of how self-help not only polices violations of convention but is also itself partly conventional in nature. (225))

These discrepancies counsel against any strong form of comparativism in theorizing constitutional self-help. They do not necessarily undermine more limited forms of intellectual arbitrage, however, such as the effort to extract organizing principles from different areas of law so as to consider how government practices stack up against those principles. And in any event, even if private law is placed to the side, there is another legal regime that more closely parallels the separation of powers with regard to managing conflict: public international law. It should go without saying that the comparison is inexact. Notably, nation-states may use military force against one another, which generates special pressure to regulate self-help ex ante. I will consider the implications of this and other points of disanalogy in Part IV.226

But the two systems share important features, such as the dual role of public institutions as the primary authors and addressees of law, the tension between these institutions' formal equality in law and the potential for significant power imbalances, the prominence of customary norms as against codified rules, the broad scope for reciprocity and repeat play, and the modest scope of judicial review. Both systems are at the same time deeply dependent on, and vulnerable to, self-help by state actors.

This observation would not have surprised the Framers, who appear to have drawn on international balance-of-power theories in developing the domestic separation of powers. (227) As recent scholarship has underscored, international law and constitutional law are beset by fundamentally similar problems of substantive uncertainty, democratic legitimacy, and--for lack of a centralized compliance authority standing above the state--enforceability against government officials. (228) Their conceptual and practical connections on these axes are foundational, so much so that it makes sense to speak of "public law" as a domain that straddles the two. (229)

In pursuit of interbranch self-help insights, then, it seems appropriate to look not just beyond constitutional law but also beyond our borders. This is especially the case because international law, unlike constitutional law, has developed explicit, trans-substantive rules for regulating conditional self-help.

B. The International Law Solution: Countermeasures Doctrine

Among its so-called "secondary rules of responsibility," public international law contains a host of remedial doctrines that regulate self-help by states above and beyond the "primary" norms that dictate what they may and may not do ab initio. The principle of states' "untrammeled right to self-help" was a pillar of classical international law, (230) along with stringent notions of national self-determination and control over a defined territory. International lawmakers in the post-World War II era have endeavored to retain ample space for horizontal (state-to-state) enforcement, while limiting its negative externalities, enhancing formal dispute resolution mechanisms, and preserving the primacy of the United Nations system.

Most famously, the U.N. Charter recognizes an "inherent right of individual or collective self-defence" for states subject to actual or imminent armed attack, "until the Security Council has taken measures necessary to maintain international peace and security." (23)' The right of self-defense may permit forcible responses, or reprisals, which otherwise would be unlawful. (232) International law also recognizes necessity as a basis for failing to fulfill certain obligations, in cases where that failure is "the only way a State can safeguard an essential interest threatened by a grave and imminent peril." (233) More mundanely, the international system allows a wide scope for retorsions: nonforcible acts of lawful retaliation, such as the limiting of diplomatic relations. (234) Although some have suggested that retorsions are subject to principles of proportionality, necessity, or good faith, the mainstream view is that any such constraints are not legal but political in nature. (235) Retorsions are an example of what I have been calling general self-help. (236)

Between the life-and-death imperatives of self-defense and the diplomatic rituals of retorsion sits the law of countermeasures. Countermeasures are nonviolent "measures that would otherwise be contrary to the international obligations of an injured State vis-a-vis the responsible State, if they were not taken by the former in response to an internationally wrongful act by the latter." (237) Which is to say, they are conditional self-help privileges.

Countermeasures have a long history in international law. (238) By the late twentieth century, they had been accepted, in some form, by the International Court of Justice in cases such as Gabcikovo-Nagymaros Project (239) and by distinguished arbitral tribunals in cases such as the Air Service Agreement award. (240) In the latter case, the tribunal approved the United States' cancellation of Air France's Paris-to-Los Angeles route, which in normal circumstances would have constituted a clear violation of the countries' air service agreement, in response to France's disruption of Pan America's London-to-Paris route. (241) Similar logic also plays a prominent role in instruments such as the Vienna Convention on the Law of Treaties, which provides that a material breach of a bilateral treaty entitles the injured party "to invoke the breach as a ground for terminating the treaty or suspending its operation in whole or in part." (242)

The most important statement of the law of countermeasures now appears in the Articles on Responsibility of States for Internationally Wrongful Acts, issued by the International Law Commission (ILC) in 2001. (243) Although they remain "soft law" (rather than a binding treaty) and have proven controversial in certain respects, these Articles are regarded by many as authoritative. (244) They elaborate a general regime of legal responsibility to govern the rights and duties of states in situations where an international obligation has allegedly been breached. This regime is meant to be independent from, and neutral on, questions concerning primary norms, and to "apply to the whole field of the international obligations of States." (245) Instead of tailoring remedial rules by subject matter, the Articles "presume that international law is a unified body of law," at least at a high level of abstraction. (246) The Articles function as "residual," or default, principles, which may be modified or superseded by more specialized rules in particular treaty regimes or customary domains. (247) The General Agreement on Tariffs and Trade, for instance, has almost entirely displaced the Articles with its own regime of responsibility, in which a Dispute Settlement Body of the World Trade Organization (WTO) must authorize all countermeasures in advance. (248) Even in this context, however, adjudicators have increasingly looked to the Articles to inform and confirm interpretations of WTO law. (249)

In developing the Articles on countermeasures, the ILC wrestled with the fundamental dilemma of self-help outlined above. Skeptical states emphasized countermeasures' potential to generate abuse, destabilize international law, and exacerbate inequalities of power, providing "cover for cowboy diplomacy by rich, powerful states." (250) Against these concerns, it was noted that countermeasures serve a valuable enforcement function and that the articulation of limiting principles could provide a check on aggressive applications. The ILC ultimately chose to acknowledge that "countermeasures are justified under certain circumstances," while subjecting them to explicit "conditions and limitations" to keep them "within generally acceptable bounds." (251)

These conditions and limitations are stringent. Countermeasures may be directed only against states that are responsible for prior, internationally wrongful acts 252: "A State taking countermeasures acts at its peril, if its view of the question of wrongfulness turns out not to be well founded." (253) Except in urgent cases of necessity, countermeasures must be preceded by notice, demand for cessation or reparation, and an offer of negotiation. (254) They may not be taken if the responsible state's wrongful act has ceased and a dispute settlement procedure is underway. (257)" They must be "commensurate with," or proportionate to, "the injury suffered." (256) Although they are not required to be "reciprocal" (that is, identical or closely related in kind to the offending behavior of the responsible state), reciprocity increases the likelihood of proportionality. (257) Countermeasures must also be terminated as soon as the responsible state has complied with its legal obligations, (258) reversible in their effects as far as possible, (259) and deployed "instrumental[ly]," (260) for the purpose of securing compliance with the responsible state's international obligations rather than exacting punishment. (261) Finally, countermeasures may never disturb obligations arising under ongoing dispute settlement procedures, nor may they contravene principles of diplomatic and consular inviolability; fundamental human rights; the U.N. Charter's restraints on the use of force; or peremptory norms such as the prohibitions on genocide, slavery, and torture. (262)

General international law, as reflected in the ILC's Articles, has thus come to recognize the legitimacy of conditional self-help, but only when cabined by an array of substantive and procedural constraints. In many cases, no centralized body will be in a position to enforce these constraints. The lawfulness of countermeasures will be judged by the parties, expert bodies, and the international community, just as the lawfulness of the alleged initial breach will be.

C. Organizing Principles

Like all legal regimes that provide for second-party enforcement, the Articles on countermeasures can be understood, in schematic terms, as an effort to manage the dilemma of self-help. The overarching goal is to harness the benefits of self-help--in particular, enhanced deterrence and reduced administrative costs and delay--while minimizing the likelihood of negative spillovers, errors, and abuses of power and procedure. (263) The Articles do not speak in cost-benefit terms, and any aspiration to "optimize" such a vast swath of public law may well be quixotic. But the Articles' approach to countermeasures is sensible in light of these policy considerations.

The notice and demand requirements, for instance, may reduce error and abuse by slowing down the pace of self-help, publicizing the injured state's legal views and intentions, and affording alleged wrongdoers a grace period in which to change or explain their conduct. The limitations on the use of countermeasures during the pendency of a dispute settlement procedure channel states away from self-help when the administrative costs of third-party resolution are relatively low. The prohibitions on use of force, human rights violations, and targeting of third parties work to contain the risk of violence and cycles of escalation; so do the requirements of proportionality, prompt termination, and proper motive (redress rather than retribution). And the mere existence of a doctrine that purports to regulate an area once thought to be beyond law provides a focal point for negotiation and criticism, enhances the reputational risk for states that use aggressive self-help tactics, and lends plausibility to charges of unjustified retaliation made by otherwise non-credible law-breaking states. The law of countermeasures decreases the odds, however marginally, of a vicious regress whereby basic norms of fair play lose all purchase whenever the primary legal norms are believed to have been breached.

Although the point is not critical for this Article's purposes, much of the domestic private law on self-help appears to share a broadly similar normative structure. (264) A Vanderbilt Special Project on self-help observed in 1984 that the two "principal factors which indicate that self-help will be acceptable are that the available judicial remedies are somehow inadequate and the threat of a self-help remedy to society's interests in law and order is minimal." (265) American legislatures and courts have, over time, significantly curtailed many of the conditional self-help privileges available at common law. To take just one prominent example, when seeking to repel invasions of one's real property, owners today generally must limit themselves to reasonable, or "proportionate," measures addressed to imminent threats, give advance warning before applying any force, and refrain from applying deadly force. (266) These limitations parallel the requirements of proportionality, notice and demand, and imminence under general international law.

In line with the Vanderbilt Special Project's observations, Richard Epstein has emphasized that "reasonableness" limitations permeate self-help doctrine and has suggested that they act as a brake on negative spillovers. (267) Across substantive areas, Epstein further contends, self-help law "pairs a quick, cheap and reliable remedy with incomplete relief... which by definition and design does not leave the aggrieved party as well [off] as he would have been if the other party had faithfully performed its obligations in the first place." (268) Lawmakers may affirmatively deny the possibility of complete, state-enforced relief in situations where a party uses self-help. For instance, in some U.S. jurisdictions, a mortgagee who resells a foreclosed property is prohibited from subsequently seeking a deficiency judgment against the mortgagor; (269) if the mortgagee wishes to exercise the self-help privilege of power-of-sale foreclosure, then she must forfeit a valuable remedial option. Extending Epstein's insights, Adam Badawi has recently argued that in fields such as contracts and property, self-help law can "be understood as a mechanism to force investments in accuracy" by funneling mistake- and spillover-prone cases to state authorities and relaxing the rules of engagement where legal rights are clearer. (270) Thus, efforts to recapture one's chattels are treated much more leniently if the owner is in hot pursuit of an item taken from her without any claim of right. (271)

Synthesizing and simplifying these observations, we can provisionally identify a handful of generic strategies that have been developed to tame conditional self-help. Mutatis mutandis, these strategies recur throughout domestic and international law.

1. Proportionality as a global norm. Virtually every self-help regime insists that conditionally lawful measures be proportionate to the other party's alleged wrong. Alternatively phrased in terms of reasonableness, commensurateness, or the like, this is the basic substantive standard governing all self-help law.

2. Notice and demand requirements. Virtually every self-help regime also insists on some form of notice of intent or demand for cessation in advance of conditionally lawful measures, with exceptions for cases of urgency. This deliberation- and publicity-generating mechanism is the basic procedural tool of self-help law.

3. Incentivizing adjudication. In order to channel parties into formal dispute resolution in situations where the risks of self-help are seen as especially high (though not high enough to ban it outright), the relative cost of self-help may be raised. For instance, lawmakers may subject self-helpers to ex post discipline, permit courts to award extra-compensatory damages, or withhold certain benefits from parties who have previously pursued self-help.

4. Categorical prohibitions. Self-help regimes frequently forbid certain inherently dangerous, costly, or irreversible measures, such as the use of deadly force or the targeting of third parties. These same measures may be especially likely to reflect a retributive purpose and especially unlikely to serve a restorative or corrective function.

5. Time limitations. Self-help regimes frequently restrict the window of time in which conditionally lawful measures may be taken after the other party's prior or impending breach.

Although I cannot begin to prove the point here, the discussion in this Part is sufficient, I think, to support the positive hypothesis that every mature system of self-help regulation relies on a combination of some or all of these strategies. Does constitutional law?

IV. COPING WITH CONSTITUTIONAL COUNTERMEASURES

The answer to the question just posed is a qualified "yes." In the balance of the Article, I will try to demonstrate that U.S. legislative-executive conflicts are regulated--already--by a rough set of constitutional conventions analogous to the international law doctrine of countermeasures.

Attending to these conventions of self-help, I will further argue, has the potential to yield a range of analytical and practical payoffs. It enables us to move beyond metaphors like hardball and showdowns in explaining how government actors register and manage disagreement--to return to the precincts of law an area that constitutional scholars have abandoned to game theory and grand strategy. In particular, a self-help perspective may help us to refine as well as to generalize criticism of President Obama's approach to congressional obstruction; to rejuvenate the strain of separation-of-powers theory that emphasizes functionality alongside friction; to disambiguate constitutional law by making it more acceptable for officials to confess violations of first-order norms; and to develop richer models of constitutional conflict and constitutional change within and beyond the branches.

A. The Latent Doctrine of Constitutional Countermeasures

In their influential treatments of intragovernmental conflict, Mark Tushnet and coauthors Eric Posner and Adrian Vermeule appear to assume that outside of judicial review, "constitutional hardball" and "constitutional showdowns" occur in an essentially unregulated zone. (272) The branches fight over their legal and quasi-legal authorities, but the fight itself is not governed by any higher-order normative principles. (273) The gloves come off.

This assumption is plausible. As a null hypothesis, we might imagine that there are no identifiable unwritten, non-judicially-enforceable norms that constrain interbranch conflict generally or retaliation specifically. Rather, elected officials are constrained in these matters only by "politics" and realize that, if the public disapproves of how they act, they may pay a political price. The strident rhetoric of hardball and showdowns is entirely appropriate, because the currency of this realm is political power, the prevailing ethic one of antagonism and opportunism.

However, this assumption need not hold true as a logical matter--as we saw in the previous Part, it is perfectly possible to have "rules of responsibility" that fetter government disputants (274)--and indeed it does not appear to hold true in practice. Against the null hypothesis, I submit that there is in fact a set of identifiable, second-order norms that constrains legislative-executive conflict. The set includes expectations of proportionality, categorical prohibitions, notice and motive requirements, and the partial privileging of judicial review.

Taken individually, these conventions of self-help play an important role in structuring various sites of contestation, such as the nonenforcement of statutes. Taken together, they amount to a latent doctrine of constitutional countermeasures: an inchoate, imperfect version of the principles for regulating conditional self-help that one finds in international (and private) law, (275) embedded within our separation-of-powers conventions. If I am right about this, then constitutional scholars may be well served not just by a new conceptual framework but also by a new linguistic register in which to consider interbranch conflict, one that sounds more in responsibility and restraint than in domination and violence. (276) Even as the conventions of self-help flesh out the picture of constitutional contestation suggested by "hardball" and "showdowns," they may simultaneously recast this picture in less menacing terms.

As in all self-help regimes, proportionality is the basic substantive standard governing irregular attempts to redress perceived wrongs by and within the political branches. In the public sphere, this can be seen most vividly in the way that charges of disproportionality are used to delegitimize acts of self-help. (277) Thus, in response to efforts last summer to limit Senate obstructionism, defenders of the status quo countered that the plan to change filibuster rules without the usual two-thirds supermajority vote represented a "threat to blow the Senate up." (278) Previous plans to tighten the filibuster rules for judicial nominations were similarly tarred by opponents as the "nuclear option." (279) Shorn of its apocalyptic imagery, this rhetoric amounts to a claim that the re medial measures under consideration were excessive in light of the alleged wrong they were targeting.

Conversely, government officials who seek to exercise self-help take pains to demonstrate that their tactics are proportionate-and furthermore that the situation is urgent ("We can't wait!") and that their motives are appropriately corrective rather than retributive or exploitative. All recent Presidents, for instance, have declared that they would assert executive privilege over materials requested by a legislative body only "in the most compelling circumstances." (280) Senators pushing to reform the filibuster through a simple majority vote have repeatedly emphasized the "modest" nature of the changes they seek, in relation to the gravity of the problem. (281) Statements such as these may be self-serving justifications, to be sure, but that in itself does not rob them of regulative force or of evidentiary value for determining the existence and content of self-help norms. (282)

In addition, the standard remedies associated with the branches' conditional self-help powers (283) are reciprocal, in the sense that they are closely bound to the motivating wrong, and hence proportionate in more concrete, formal terms. (284) Under prevailing norms, the President does not decline to enforce or defend statute A, or to comply with subpoena B, because she believes that congressional behavior C is improper and wants to pressure Congress into ending C. The scope of the President's main self-help powers is defined by, and extends no further than, the particular legislative measure deemed to raise constitutional problems. Impeachment and contempt, for their part, are openly predicated on discrete offending acts. According to Supreme Court dicta from 1821 that has hardened into an "accepted maxim," (285) congressional contempt sanctions must also be limited to "the least possible power adequate to the end proposed." (286)

The pull of a proportionality constraint, along with the associated expectations of proper motive and prompt termination, (287) has been evident at some of the most critical junctures in our constitutional development as well as in the ordinary course of governance. Congress's determination in the wake of the Civil War to exclude Southern representatives, with ratification of the Fourteenth Amendment set as the price of readmission, was arguably the most radical instance of conditional self-help in the nation's history. Yet extraordinary as this measure was, it was defended by its Republican sponsors not only as a legitimate consequence of war but also as the least draconian, least federalism-flouting means available--as a constitutionally conservative remedy compared to "alternatives that posited the destruction of the Southern states and their remission to territorial status, or that authorized permanent federal supervision of state political institutions under the Guarantee Clause." (288) The exclusion remedy was proportionate, its sponsors insisted. (289) The constitutional wrong it was designed to rectify was just very, very grave.

General self-help powers do not generate the same intrinsic pressure for proportionality, given that their validity does not necessarily depend upon another's wrong. Yet even in their case, we observe a bias against disproportionate and nonreciprocal remedies. It is all but unheard of for the President to veto a bill concerning issue D out of a desire to end congressional practice C, or for a congressional committee to investigate one matter in retaliation for perceived executive misconduct in another matter. The Advice and Consent power is now a significant outlier in this regard, as it has become fairly common for Senators to hold or filibuster nominations or (less often) legislation for reasons that lack a direct connection to the nominee or the bill. (290) These unusually attenuated maneuvers are subject to intense criticism on this basis, (291) however, and the actors involved continue to abide by certain outer limits of proportionality. When Senator Richard Shelby tried in early 2010 to place a "blanket hold" on all of President Obama's pending nominations, he was roundly denounced--even by Republican colleagues--for transgressing all such limits, (292) and in short order he backed down. (293)

At a higher level of generality, an ethic of proportionality helps to maintain the boundary between the "large-C" Constitution and the "small-c" constitution. Recall that the former consists of norms that are grounded in the canonical document and viewed as legally binding, while the latter consists of norms that guide the processes of government but are not so pedigreed. (294) Interbranch self-help polices both sets of norms, as discussed in Parts I and II. A convention of self-help polices the divide itself, by forbidding noncompliance with large-C norms in response to breaches of small-c norms. No President ever contends, for example, that lawful but awful behavior by Congress liberates her to treat a duly enacted statute as void. The remedy would be seen as out of line with the critique.

This convention can exert justificatory pressure in two directions: pressuring government actors (i) to justify their self-help measures as consistent with large-C norms, as President Obama has done in the cases listed in the Introduction, or (ii) to characterize the other branch's alleged misdeeds as themselves violations of large-C norms. These pressures, in turn, help explain how arguments and practices move over time from "off-the-wall" to "on-the-wall," through the efforts of entrepreneurial Presidents and legislators to leverage critiques of their rivals to reconfigure the boundaries of fair play and constitutional meaning. (295) If specific cases of intragovernmental self-help can propel constitutional innovations, (296) then conventions of self-help delimit their argumentative form. A meta-principle of proportionality not only reflects but also secures the basic normative structure of separation-of-powers law.

Beyond proportionality, a slew of conventions impose the equivalent of notice or demand requirements on executive self-help. (297) As already noted, Presidents acknowledge an obligation to seek a negotiated solution with congressional overseers before asserting executive privilege over requested docu-documents. (298) The President is further expected to inform relevant members of Congress in advance of all intended recess appointments, (299) international agreements, (300) vetoes or constitutional signing statements, (301) and determinations not to enforce or defend statutes. (302) Whatever the scope of the President's constitutional authority to unilaterally change the course of policy or violate the will of Congress, convention appears to dictate that such moves not be made in deep secrecy, without a prior or at least prompt explanation given to lawmakers. (303) Some of the bipartisan outrage inspired by President George W. Bush's defiance of laws like the Foreign Intelligence Surveillance Act traded on this second-order norm of how self-help is to be exercised, not necessarily on any substantive disagreement with the Administration's constitutional claims. (304)

Other conventions moderate executive self-help by facilitating judicial review. For at least two decades, OLC has taken the position that the President should "base his decision to comply (or decline to comply)" with a statute he deems unconstitutional "in part on a desire to afford the Supreme Court an opportunity to review the constitutional judgment of the legislative branch." (305) This convention has resulted in numerous "enforcement-litigation gaps," (306) whereby the executive continues to enforce a law against third parties and then declines to defend the law when they challenge it in court. So strong is the underlying norm, according to Neal Devins and Saikrishna Prakash, that while executive branch officials "express fealty to the duties to enforce and defend, they often act as if they only have a duty to create a justiciable controversy." (307) Another line of OLC doctrine suggests greater scope for Presidents to decline to enforce laws that are indisputably invalid. (308) This line of doctrine reinforces the norm against nonenforcement in the modal case of disputable constitutionality, and serves the important function of funneling the most mistake-prone cases into court. (309)

Still other conventions impose categorical constraints on interbranch selfhelp. Government self-helpers may not engage in physical violence, disregard judicial judgments or what is seen as clear constitutional text, (310) or violate the rights of private parties. These norms have been so deeply internalized that they are almost never broached, much less breached. They go without saying. In this regard, it is important to keep in mind those self-help moves that officials do not make--the countless times that an aggrieved President does not, say, try to dissolve Congress, or install a new Supreme Court Justice by fiat, or for that matter urge Congress to increase the Court's size. (311) Conventions of self-help may have the most bite in rendering politically untenable, taking off the table, retaliatory measures that are never made or even contemplated. (312) To focus only on observable self-help is to overstate the permissiveness of the system.

In sum, a close look at U.S. government practices suggests that numerous conventions regulate constitutional self-help, particularly the core case of conditional self-help; that these conventions echo many of the key principles used to discipline countermeasures in international law; and that their combined effect is to make intragovernmental conflict substantially more orderly and civil-more norm-bound--than is often assumed. The latent doctrine of constitutional countermeasures shapes and stabilizes the varied mechanisms of "checking and balancing." Although I cannot conclusively establish these points in the space I have here, I believe the foregoing examples make out a strong prima facie case. If anything, I suspect this discussion has understated the breadth of the phenomenon. There may well be many more conventions of self-help in the U.S. system that deserve acknowledgement and attention.

B. The Dignity of Retaliation: On Taking Self-Help Seriously

By attending to conventions of self-help, then, we can begin to reinterpret intragovernmental conflict in a more sympathetic and nuanced manner, to resubmit the study of this conflict to the language of the law. Even so, the existence of these conventions may not seem all that impressive. The basic substantive standard, proportionality, is a famously fuzzy concept in international law. (313) Perhaps identifying it as a constraint in this context is just a fancy way of saying that politicians do not wish to be seen as "going too far." All of the above-mentioned norms may be susceptible to manipulation and violation, given that judicial enforcement does not back them up. Moreover, a great deal of political behavior, as well as constitutional law, likely rests at bottom on reciprocity, reputation, and repeat play; (314) some of the conventions that contribute to the stability of our system may be epiphenomenal expressions of these underlying dynamics.

These are all reasons to develop, not to discount, the idea of constitutional self-help. Even if some of the conventions just described seem unremarkable at a retail level, the structural logic that connects them is compelling. It would be odd, from an institutional design perspective, to impose strict threshold conditions before certain self-help powers may take effect, but then to allow unknown or unbridled uses of those powers once triggered. The preceding section showed how the separation of powers "in action" avoids this mismatch between restricted right and unrestricted remedy, even though the separation of powers "in the books" by no means guarantees it. (315) Only when we take the conventions of self-help as an integrated suite can we see this feature of our government practices.

Proportionality can indeed be a fancier way of saying that one may not go too far. (316) But that is a momentous thing to say. The fact that American politicians defend their retaliatory actions as proportionate reflects and reinforces a consensus that intragovernmental conflict is not a free-for-all. It allows self-helpers to be judged and criticized even when their accusations against the other side are valid. It may also trigger the "civilizing force of hypocrisy" (317) requiring politicians to be more measured in their self-help than they might otherwise prefer, if they wish to maintain consistency with their prior statements about the importance of the norm. The open manner in which proportionality is debated, both inside and outside the Beltway, facilitates the checking and legitimating forces of publicity and public opinion more generally.

Proportionality rhetoric is not just cheap talk. The cost to the speaker of trumpeting an ethic of restrained retaliation is greater than zero. As in international law, furthermore, the mere existence of proportionality talk may generate "compliance pull," (318) progressively enhancing the status or salience of the norm and thereby narrowing the range of retaliatory moves that are seen as acceptable. (319) The more refined our discourse of proportionality--the better our ability to pinpoint what it requires in specific contexts--the more constraint may be exerted.

Just as some peripheral vagueness does not imply that conventions of self-help will be indiscernible, a lack of judicial enforcement does not imply that they will be inefficacious. These conventions are presumably followed (by and large) for many of the same reasons that all constitutional rules and conventions are followed (by and large), including equilibrium political and institutional forces; officials' professional socialization and reputational concerns; and constraints associated with the party system, independent media, civil society, and reverence for checks and balances. (320) Across the U.S. government, the breadth, frequency, and overlapping nature of interactions among the branches may broadly support norms of moderation by generating ongoing "multiplex" relationships that guarantee to each "a rich menu of future opportunities to render self-help sanctions." (321)

This is an important point of potential contrast with the international system, as well as certain other national systems. Our domestic conventions of self-help are generally less fleshed out, less stringent, and less prominent than the international rules on countermeasures. But this makes sense, because we do not need to constrain retaliating branches as much as the international system needs to constrain retaliating nation-states. Spongier norms will generally serve in the constitutional context, given the various institutional structures, cultural characteristics, and ideals of solidarity that curb the worst abuses of self-help. In a fragile democracy, concerns about self-help conventions' falling apart, about cycles of retribution leading to a collapse of law and order, have greater bite. The president who feels aggrieved might just go ahead and break up the parliament. At the international level, the mightier state might just go ahead and cut off all intercourse with its weaker rival. Many factors combine to make analogous moves largely unthinkable in the United States.

Of course, intragovernmental conflict does occur here, frequently sparked by one side's perceived violation of a constitutional rule or convention. Yet if government actors are willing to violate those first-order norms, why wouldn't they also be willing to violate second-order norms of permissible retaliation? Why wouldn't the sociological conditions that produce a breakdown at the first level tend to produce a breakdown at the second, or third, or nth level ? Whatever the answer, such vicious cycles appear to be the exception rather than the rule as a descriptive matter; the conventions of self-help appear to be highly resilient. This resilience might reflect the fact that government actors have particularly strong endogenous incentives to abide by norms of moderation and fair play, insofar as these norms "effectively bundle numerous prospective policy outcomes" or help preserve the larger separation-of-powers "game." (322) Or it might reflect the fact that even if government actors have no clue what the equilibrium strategy is in any given conflict, they may be aware that such norms have served their institution reasonably well in the past and therefore rely on them as decisionmaking heuristics.

Alternatively, conventions of self-help may exert an especially strong normative influence because of the sense in which they implicate basic fealty to the constitutional order or basic tenets of morality. (323) The core principles of self-help doctrine--retaliate only in a proportionate manner, try to work things out first, spare innocent parties--are both easily comprehensible and consonant with ethical ideals such as the Golden Rule. It takes little constitutional sophistication to grasp the threat to good governance posed by a "nuclear option." Plausible accusations about breaches of these conventions, accordingly, may tend to resonate with important nongovernmental audiences, in particular median and independent voters, in ways that bolster their constraining force on government actors.

In any case, norm-following always gives rise to an infinite regress concern. The more rules that one has to follow, however, the harder it is to violate them all. This is in the nature of fail-safes. The very existence of an additional layer of norms applicable to intragovernmental conflict should tend to curb efforts to vanquish the other side.

The possibility that many of our separation-of-powers conventions have a game-theoretic underpinning of some sort--so that senatorial courtesy, for instance, persists because of the expectation of retaliation or reciprocity arising out of a repeated game (324)--hardly means that they should not be of interest to lawyers. At worst, this possibility means that we might wish to turn to disciplines like political science or philosophy to understand these conventions better. The same is true of every governmental norm. Game theory has little if anything to say about the substantive content of these constitutional arrangements. Nor does it have much to say about where government actors' preferences come from, or why they would seek to safeguard the prerogatives of their office beyond their own tenure. What is distinctive about the field of interbranch conflict is not that it is amenable to formal modeling. What is distinctive is that we do not even have a legal discourse to which such reductions could be applied.

Even if one could demonstrate that a certain convention has its origins in certain equilibrium forces, it would be a fallacy to conclude that this undermines the convention's normative character. (325) And virtually all of the conventions of self-help outlined above, along with the vast majority of separation-of-powers conventions more broadly, appear to be at least partially "thick" in our constitutional culture: they have been internalized to some extent by officials and opinion-makers "as a rule of political morality." (326) Instrumentalism aside, executive branch self-helpers genuinely seem to believe that they should act proportionately and non-vindictively, give advance notice, support judicial review, not target third parties, and so forth. Or at least, they seem to recognize that others hold these beliefs, and therefore they purport to do likewise. Anyone who wishes to grasp the phenomenology or the practical morality of the separation of powers--not just its written rules and observable outputs but also the way it is experienced by government participants--has reason to care about the conventions of self-help.

By forsaking the language of law in favor of sports metaphors and social science, constitutional scholars have thus blunted their ability to assess constitutional practice from an internal as well as an external perspective. (327) A self help framework cannot tell us which side will or should prevail in any given interbranch conflict. But it nonetheless gives us a richer set of resources with which to investigate this conflict's legal and normative character; it allows us to see retaliation as both a subject and a source of constitutional regulation. To the extent that countermeasures principles can promote stability and fairness in a domestic system as in the international system, a self-help framework may also provide government actors with a more satisfying set of reasons for accepting these principles as obligatory standards of conduct.

Moreover, self-help offers an especially apt lens through which to view our current constitutional period, with its twinned anxieties regarding legislative dysfunction and executive aggrandizement. As applied to government gridlock and efforts to circumvent that gridlock, a self-help framework has deep resonance with the Founding vision. The doctrine of constitutional countermeasures provides a potential bridge between the two major accounts of the Framers' separation of powers: the view that their fundamental purpose in adopting this principle was to prevent tyranny, and the view that their fundamental purpose was to create a government that is able to get things done.

It has become commonplace to observe, as Justice Brandeis once put it, that the aim of the separation of powers is "not to promote efficiency but to preclude the exercise of arbitrary government." (328) We have already seen how the conventions of self-help can serve the Brandeisian vision by disciplining interbranch struggle. Yet as many have argued, the Framers did not accept Justice Brandeis's antinomy. Prominent among their reasons for embracing the separation of powers was the promotion of energetic and responsible governance in the common interest. (329)

This is the strain of separation-of-powers theory that best aligns with the use of otherwise impermissible measures in response to partisan obstructionism. (Whether it ultimately justifies these measures is another

matter, inescapably dependent on one's theory of constitutional legitimacy and the particulars of the case at hand.) On the efficiency account, there are not just discrete clauses of the Constitution that authorize discrete types of self-help. There is also a structural principle of workable government that may inform and support presidential adaptation in the face of an uncooperative Congress, and vice versa. Those who would defend such adaptation have no need to reconceive the Constitution for the Age of Dysfunction. We already have a prominent theory of the separation of powers that identifies policy paralysis as a constitutional evil--and hence a theory that might be mobilized to try to legitimate some of the most controversial forms of contemporary self-help, even as the theory of countermeasures might be mobilized to ensure the President's goals are pursued in a law-like manner. Self-help doctrine can render less arbitrary the struggle for efficiency.

C. Why Can't We Wait?: The Missing Discourse of Constitutional Self-Help

Seen in this light, the jarring thing about the American system of separated powers is not that there is so much retaliation or quasi-constitutional custom, but rather that there is so little acknowledgement of either. Government officials hardly ever invoke constitutional "self-help" or "conventions" as such. Yet if the descriptive claims advanced in this Part are valid (or largely so), then the absence of self-help and conventions from our constitutional discourse is not evidence of their insignificance so much as it is evidence of the poverty of the discourse. An appreciation of these concepts may allow us to cultivate more honest and productive dialogue around the separation of powers.

For instance, if we were to follow through on the idea of conventions as distinct from politics, then we could not just dismiss out of hand the view that the Senate has a meaningful obligation--albeit not a strictly legal one--to restore its historic practice of giving all senior executive branch nominees who have made it out of committee a floor vote. (330) We would have to think much more carefully about possibilities for congressional misbehavior outside of passing unconstitutional statutes. When the President responds, we would likewise have to think much more carefully about possibilities for executive misbehavior above and beyond the written constitutional floor. Whatever the best view of conventions' normative status, simply conceiving of the branches as conventional duty-bearers would enable more nuanced conversations about how and why the branches invite as well as engage in reprisals.

If officials and observers were self-consciously to adopt a theory of countermeasures, it could go substantially further toward disambiguating constitutional law. By helping to distinguish between more and less lawful remedial approaches, self-help theory can also help to distinguish between norms regarding the content of the branches' generally applicable obligations and norms regarding how violations of those obligations are to be judged and corrected. Countermeasures principles, recall, are superimposed on a set of "primary" rules. (331) Instead of always pretending that their actions are consistent with these rules, government actors in an explicit regime of constitutional countermeasures may be liberated to acknowledge facial inconsistency--and then defend their behavior as conditional self-help. Legal disagreement would be displaced to some extent from the first-order norms of constitutional conduct to the second-order norms of acceptable retaliation, creating greater ruleness and clarity as to the former.

President Obama's approach to congressional resistance illustrates the problem. Through his "We Can't Wait" campaign, (332) the President has been constructing an extended moral and consequentialist argument about how Congress has been acting in deeply irresponsible ways, ways that threaten constitutional values. Lacking an account of constitutional self-help on which to draw, however, he has been unable to link this argument to an appeal for enhanced discretion to pursue his objectives. His searing indictments of legislative obstructionism have remained legally inert.

In its lengthy opinion on Richard Cordray's intrasession recess appointment, for example, OLC mentions "practical" considerations no fewer than eleven times, without once mentioning that Senate Republicans blocked a floor vote on Cordray in an arguably unprecedented manner, or that his recess appointment was an inherently time-bounded, reciprocal response. (333) In its lengthy briefs filed in court in defense of the Dreamers policy, the Justice Department similarly declines to note the use of the filibuster in derailing the DREAM Act. (334) Legislative gridlock goes unmentioned in the various documents that defend the NCLB waivers. (335)

The Administration's official legal scripts have effaced the actual motivations and developments that seem to be driving some of its most controversial behaviors. In so doing, they have obscured these behaviors' real sources of legitimation. The absence of a vocabulary of constitutional self-help has driven a wedge between the Administration's professional and political discourses, degrading both.

A self-help framework might put President Obama's campaign on a firmer footing. (336) Barred from claiming that congressional Republicans' violations of small-c constitutional norms entitle him to violate large-C norms because of the meta-proportionality principle of interbranch self-help, (337) the President's lawyers (like many executive branch lawyers before them) have resorted to subtler forms of interpretive self-help. (338) The cases listed in the Introduction and Part II.C are prominent examples. (339) The basic pattern that has emerged in these cases and others combines a latitudinarian reading of statutory and constitutional restrictions with a suggestion, typically made in a less formal setting, that Congress's institutional pathologies have enhanced the President's discretion as a matter of policy if not also of law. (340) The implicit theory seems to be that when the lawmaking branch of government is broken, the law-executing branch must enjoy greater freedom to utilize the laws with which it is stuck. Dysfunction yields discretion.

No Administration official, however, has publicly articulated this theory, or any other self-help theory. No official has acknowledged the looseness of the President's readings of legal texts and then endeavored to justify that looseness as an unconventional but not strictly unconstitutional response to the failure of congressional lawmaking. (341) Although this is the self-help move to which the President's lawyers seem most drawn, they have been unwilling to embrace it on these terms. The failure to acknowledge and defend conditional self-help as such is itself contrary to basic principles of self-help law. (342)

It may also be poor legal strategy. The one time that a top Administration lawyer hinted at the idea of interpretive self-help in court--when the Solicitor General suggested in the Noel Canning oral argument that the recess appointment power "may now act as a safety valve given [current levels of Senate] intransigence" --he was rebuked by Justice Ginsburg for departing from his written submissions, and he ultimately found no supporters. (343) Perhaps this particular self-help plea was destined to fail before a Court predisposed to "institutional formalism," (344) but the Solicitor General had not laid the groundwork necessary to give it a chance. (345)

There are many other self-help moves that might be made. Consistent with the self-help principles sketched above, a less perilous alternative would be for the Administration to limit itself to reciprocal violations of convention--refusing to give advance notice of international agreements, reprogramming unobligated funds (as allowed by statute) without checking with appropriators, or the like. A more ambitious tactic would be to try to convert President Obama's critique of legislative obstructionism into a large-C critique. In his push for filibuster reform, for instance, the President could have argued that the modern, routinized version of the filibuster had come to violate the structure of the written Constitution, and hence that Senate Democrats were not legally obligated to comply with the relevant procedural rules. (346) Any given argument for conditional self-help may not succeed in the end, of course. The President's lawyers would have a heavy burden to show why contemporary forms of obstructionism deserve to be seen as constitutional evils that justify an exceptional response, as under no plausible reading of the large-C or small-c constitution is the President entitled to have his preferred policies adopted by Congress. To the extent that courts play a reviewing role, they may not be persuaded by such arguments, as Noel Canning exemplifies. So too with the public, the press, and the professoriate.

If these efforts to vindicate executive self-help were to fail, however, at least they would do so with transparency and integrity--forthright about the contingent nature of their legitimacy, openly tied to and limited by the congressional misconduct that allegedly potentiates them. The language of self-help would both enrich the terms and clarify the stakes of the debate between President Obama and his congressional critics. A self-help framework offers the most principled basis for the President, and any successor who feels similarly stuck in an Age of Dysfunction, to promote a vision of the separation of powers that links constitutional responsibility to constitutional redress.

D. Anxieties and Extensions

Applying a self-help lens, this Part has suggested, we may find that some of what looks pathological or lawless in our constitutional order is in fact compatible with well-known regulatory models. This observation does not amount to a defense of existing practices. As a justificatory framework, self-help theory is inherently limited: the validity of any given act of retaliation always depends upon an assessment of the other side's alleged wrong, and that assessment always requires a substantive theory of the relevant laws or conventions. (347) While identifying behavior such as President Obama's "We Can't Wait" campaign as an attempt at self-help can guide both justification and critique, mere identification cannot resolve whether the behavior is warranted or desirable.

It bears emphasis, more generally, that even if the United States does have a latent doctrine of constitutional countermeasures that negotiates between efficiency and anti-tyranny principles, this negotiation is unlikely to yield ideal outcomes. Longstanding interbranch norms such as the ones highlighted in this Article may be workable and attractive to a Burkean traditionalist, yet suboptimal from any number of perspectives. (348) On some readings of the Constitution, they may even be unlawful. Conditional self-help measures, as explained above, pose problems for formalists as well as functionalists insofar as they involve one branch's exercise of powers typically associated with another branch. (349) Those who believe that the Take Care Clause requires the President to enforce each and every statute, lest she usurp the legislative power to make law, will be dissatisfied with any scheme that countenances nonenforcement. (350)

It is also very possible that the actors within each branch will have mismatched incentives or capacities to act in the interests of their branch. Countermeasures regimes generally assume that participants will be motivated to police and retaliate against initial violations. This assumption is plausible in international law, where nation-states' identical legal authorities may also make breaches easier to identify and reciprocity easier to attain. When it comes to the branches and especially to Congress, however, institutional self-interest will often be complicated by both partisan and personal incentives. As scholars such as Daryl Levinson and Richard Pildes have highlighted, the recent (re)emergence of "exceptionally strong and polarized parties" puts significant pressure on the Madisonian model of inherently and continuously rivalrous branches. (351)

Although party competition now suffuses numerous aspects of legislative-executive interaction, it does not undercut the utility of a self-help perspective. On the one hand, partisanship clearly cannot explain all of the retaliation that occurs within government. (352) On the other hand, even when partisanship does play a driving role, officials still must channel many of their retaliatory behaviors through the Constitution's institutional framework. (353) Anyone interested in why the branches check and balance one another needs to consider partisanship; anyone interested in how they do so ought to consider self-help. Partisan dynamics interact in complex ways with the quality and quantity of interbranch self-help, (354) and the remedial tools wielded by individual Senators ensure that some amount of it is kept in constant supply. (355) But at least as a first approximation, it is plausible to worry that such self-help will occur too frequently or vigorously in times of divided government, or too infrequently or fecklessly in times of unified government (when the same political party controls Congress and the presidency). (356)

Beyond the contingencies of partisan politics, a Madisonian might worry further that the executive is structurally better organized than Congress for the consistent practice of self-help, for all the reasons that the executive is better organized to take decisive action and push legal boundaries generally. As a result of collective action problems and informational deficits as well as partisan dynamics, it is now widely believed that "Congress as a body does not systematically seek to protect its prerogatives against presidential encroachment." (357) One might consequently be concerned that even as individual members or committees of Congress will tend to over-provide certain forms of partisan self-help (for example, punitive oversight or routine use of holds by a Senator from the opposition party), Congress as a whole will tend to under-provide certain other forms of collective self-help (for example, legislation designed to redress presidential overreach), in ways that do not net out. Depending on one's assumptions and priors, this concern might seem severe. (358)

In calling attention to the role of constitutional countermeasures, then, I do not mean to tell a celebratory story. There is no shortage of reasons to lament the status quo. What I do mean to affirm is that we go wrong when we read retaliatory interbranch activity as necessarily destabilizing of good governance or rule-of-law values. There is no a priori reason to assume that all such activity will undermine rather than shore up the separation of powers. (359) As in international law, what we need are principles to distinguish the more destructive kinds of self-help from the more constructive ones. I have also tried to show that constitutional self-help can be valuable for the same reasons that self-help can be valuable in other contexts. Notwithstanding the risk of error and abuse, constitutional self-help holds out the promise of efficient deterrence, reduced transaction costs, and greater internalization of stability-inducing norms. Accordingly, the simple observation that our system contains large amounts of interbranch self-help, including conditional self-help, should not frighten us. It would be far more frightening if our system lacked robust second-party enforcement mechanisms to safeguard constitutional compliance. (360)

Against the potential theoretical and practical benefits of admitting self-help into our constitutional lexicon, what might be the costs of doing so? The most acute concern, I think, is that the very project of developing a framework for constitutional self-help will tend to facilitate opportunistic behavior--in particular, presidential power grabs. Would a theory of constitutional countermeasures only end up abetting aggrandizement?

This is the same perverse-consequences concern that the ILC faced in developing the Articles on State Responsibility. (361) Countermeasures doctrine is meant to be a tool of limitation, not of authorization or exculpation. It layers "secondary rules" on top of preexisting "primary" norms. Yet simply by bringing such dangerous self-help behavior under a legal rubric, some argued, the ILC ran the risk of legitimating that behavior and thereby advantaging the most aggressive actors. (362) It is notable in this regard that "countermeasures" and "conditional self-help" sound fairly technical and antiseptic. These labels might mask to some extent just how troubling governmental retaliation can be. It would sound rather different if, following Michel Foucault, we instead referred to this doctrine as an economy of "illegalities," in which officials constantly negotiate relations of power by pushing the edges of law and trying to get away with it. (363)

This perversity objection, however, may be less forceful than it seems. It cannot be ruled out that adding another arrow to the quiver of arguments that might be deployed in defense of constitutionally questionable practices could lead to greater presidential adventurism. But the project of developing a vocabulary of constitutional self-help has no necessary pro-executive valence, any more than the project of developing a vocabulary of residential self-help has a pro-landlord valence. (364) There are far too many contingencies in play to predict with confidence whether crisper rules in this area would ultimately generate more or less constraint. Moreover, and critically, all of the forms of self-help reviewed in this Article are already occurring, just on more opaque terms. And they are already occurring in a legal and political context that tends to be extremely favorable to activist Presidents. (365) Against this backdrop, greater attention to interbranch self-help has nontrivial checking (as well as illuminating) potential. "[T]he elaboration of a balanced regime of countermeasures," the ILC concluded, is "more likely to be of use in controlling excesses than [is] silence." (366)

As the ILC did with the intergovernmental system, American lawyers and lawmakers can work to improve our system of intragovermental self-help to the extent that they find it structurally too President-friendly (367) or otherwise misguided. Adapting Vincent Blasi's "pathological perspective," for instance, they might try to frame domestic countermeasures doctrine for the worst of times, by curtailing some of the most alarming moves that could be made by strong Presidents, even at the cost of simultaneously blocking some salutary applications. (368) They could press Congress to refuse to confirm nominees who were previously given intrasession recess appointments. They could urge a categorical prohibition on use of the avoidance canon in executive branch interpretation, or a categorical obligation on the President to pair nonenforcement of statutes and subpoenas with the facilitation of judicial review. (369) And they could ask courts to enforce or develop any or all of these principles (or, conversely, to stay even further away from legislative-executive conflict). More radically still, they could try to revamp the structure of constitutional conflict on the model of the WTO, so that a designated dispute resolution body authorizes countermeasures ex ante, in lieu of a decentralized regime of tit-for-tat sanctioning. (370)

These efforts might fail. The political will may not be there. Conventions cannot always be changed, much less fine-tuned, through critical argumentation, although it is sometimes possible. (371) Only by recognizing the existence of conventions of self-help, however, can we begin to see the regulative work that they collectively do, and so envision them as a potential site of reform.

Instead of shrinking from the idea of constitutional self-help, we should push the inquiry further. This Article has focused on legislative-executive interaction as the most prominent context for constitutional countermeasures. A self-help perspective potentially opens up a number of additional avenues for research and reconceptualization, to which I can only gesture here.

Intrabranch self-help. Most obviously, a self-help framework could be applied to interactions within as well as among the branches. As a practical matter, there is no clean line separating the two domains. On account of partisanship, conflict in Congress often stimulates and responds to legislative-executive conflict; (372) some of this Article's examples, such as the presidentially supported push for filibuster reform in the Senate, highlight the porousness of the inter- and intrabranch categories. Within the legislative process, the prevalence of informal norms is well established. (373) What is far less clear, because the question has not been posed in these terms, is whether some of these norms specifically regulate efforts to correct violations of the written rules of procedure or the unwritten first-order norms of cooperation. To the extent that such self-help conventions exist, even the most bitterly partisan, legally unconstrained struggle in Congress may be more principled, and less pathological, than it first appears.

Within the executive branch, retaliatory measures are less likely to revolve around partisanship than around rivalries spanning agencies and their White House overseers, agencies and other agencies, civil servants and political appointees, and other bureaucratic divides. Constitutional scholarship is not the only field that could profit from focused inquiry into how executive branch officials set out to redress each other's perceived wrongs through and beyond the law. If the study of interagency coordination is "all the rage in administrative law," (374) then the study of interagency conflict management presumably merits some enthusiasm as well. Is leaking confidential information to the press, for example, a recognized form of intra-executive self-help? And if so, does even this rogue behavior--a paradigm case of seeming lawlessness and venality in government--abide by norms of proportionality and reciprocity, categorical subject matter limitations, and the like? (375)

State-national self-help. A self-help framework lends itself to the study of vertical as well as horizontal contestation in government. As every student of American constitutional law knows, our history is replete with conflict between state and federal officials. The most spectacular examples of state self-help continue to haunt the constitutional imaginary: nullification and secession. The states' position lost decisively in these cases, so that the large-C Constitution is now widely (though not universally) viewed as denying states the authority, on structural and Supremacy Clause grounds, to abrogate federal law or withdraw from the union in response to allegedly unconstitutional action by the national government. (376) It took a civil war, and later the civil rights movement, to vindicate this principle. The basic self-help norm in the federalism sphere is a categorical bar on nullification and secession.

Yet unilateral efforts by state officials to remedy perceived wrongs by the national government have hardly gone away. They just tend to take subtler forms. As federal regulatory schemes have increasingly encroached upon traditional zones of state authority, states have found new ways to resist. Recent work by Jessica Bulman-Pozen and Heather Gerken suggests that states routinely "use regulatory power conferred by the federal government to tweak, challenge, and even dissent from federal law," (377) often along partisan lines. (378) Some of these uncooperative efforts are perfectly lawful, as when states exploit regulatory gaps to challenge federal policy. (379) Some of these efforts are more legally dubious, as when states go beyond what federal law requires in pursuing unlawfully present aliens, on the view that the federal executive branch has failed "to enforce the immigration laws as written." (380) We are beginning to appreciate that decentralized self-help practices are not marginal but pervasive in the modern administrative state. (381)

We do not yet have a detailed understanding of the nature and scope of many of these practices, however, or of the informal norms associated with them. We have not yet laid all the groundwork for reconciling state self-help with the triumph of federal constitutional supremacy. Important open questions include whether and to what extent state self-helpers abide by--or should be made to abide by--secondary rules of retaliation, such as an obligation to renounce certain especially worrisome tactics, defend their actions as proportionate, give advance notice of their intentions, or channel their dissent into a judicial forum. Self-help theory may give scholars and policymakers additional tools with which to identify and secure a cooperative core to uncooperative federalism.

Self-help and the secondary virtues. The value of a self-help framework potentially extends beyond law. By abandoning so much of the field of intragovernmental conflict to political pundits and social scientists, constitutional scholars may have constricted their capacity to see its ethical as well as legal dimensions. This Article has suggested that even the most rancorous confrontations in American politics generally retain an overarching, law-like integrity. They generally adhere to conventions of self-help that make them far more predictable, limited, and normatively laden--and far closer to the international law of countermeasures --than a purely partisan or game-theoretic account could hope to show. An additional cost of adopting a lawless theoretical perspective, then, may be an unwarranted invitation to constitutional cynicism and alienation. A self-help lens may be useful not only for reconceptualizing the separation of powers but also for reclaiming a sense of identification with it.

In his famous 1986 Harvard Law Review Foreword, Frank Michelman argued that the Supreme Court should aspire to model, in its own behaviors, ideals of practical reason and republican self-government that are unattainable on a national scale. (382) In a similar spirit, we might want the political branches to model, in their interactions, an ideal of restrained, respectful, civic-minded conflict management. We might want them to display what the philosopher Alasdair MacIntyre once called the "secondary virtues," such as "a pragmatic approach to problems, co-operativeness, fair-play, tolerance, [and] a gift for compromise" (383)--virtues that concern not which projects or goals are to be pursued, but rather how they are to be pursued.

Here is the thing: Congress and the President already model this ideal. Their interactions already conform, imperfectly but substantially, to a multitude of unwritten norms facilitative of pragmatism, cooperation, and fair play. These norms have been tested in recent years, and there is no guarantee that they will not deteriorate further. Our political discourse may at times seem distant from MacIntyre's standards. But the actual workings of the federal government-some of them, at least--have not been so terribly far off. A trace of the secondary virtues can still be glimpsed in the conventions of interbranch self-help.

CONCLUSION

The cases listed at the start of this Article are so vexing, not only because of the difficult issues they present on the merits, but also because of the dramatic manner in which the President resolved his own critique of Congress. We worry that brute politics may have triumphed over law. Yet unilateral reprisals of this sort do not necessarily entail lawlessness. To the contrary, they are one of our basic tools for securing both law and convention, both the "large-C" and the "small-c" constitutions. Accustomed to associating constitutional enforcement with the courts, legal scholarship currently lacks an account of these tools. It lacks a framework to parse or police the intricate terrain of intragovernmental self-help.

The development of such a framework, this Article has tried to show, can shed light on high-level questions pertaining to constitutional commitment, contestation, and change as well as on intensely practical concerns of governance. In an era marked by legislative obstructionism and "an executive style of governing that aims to sidestep Congress more often," (384) it becomes all the more vital to think systematically about the functions and limits of interbranch retaliation--and thus all the more appropriate to admit self-help concepts into the constitutional lexicon. The doctrine of countermeasures provides a model. Following the example set by their international law counterparts, American public law scholars may wish to set themselves the task of theorizing, and domesticating, constitutional countermeasures.

The place to begin is with the recognition that intragovernmental self-help is all around us, for good and for ill. This Article is an attempt to identify, sort, and evaluate it as a unified phenomenon, a cohesive remedial logic at the heart of the American constitutional project. Above and beyond any of the specific arguments the Article has advanced, I hope the analysis can stimulate fruitful lines of inquiry--on constitutional self-help, constitutional conventions, the general theory and practice of self-help, and the intersections and interactions among them.

(16.) This may not prove the best reading of President Obama's maneuvers, much less a satisfying justification for them, but it is a plausible (and, I hope, illuminating) reading. That is enough to set up the Article's larger inquiry.

(17.) See Charlie Savage, Shift on Executive Power Lets Obama Bypass Rivals, N.Y.

Garnett, Executive Overreach: How Both Parties Have Ignored the Constitution, Commonweal, Sept. 14, 2012, at 9, 10 ("In constitutional government, how and by whom things are done is at least as important as what is done and when, or how quickly.

(19.) It would be impossible to remain completely agnostic. In particular, the Article assumes it is coherent to speak of an overarching separation of powers among the federal branches of government. The notion that the Constitution adopts any "freestanding" principle of this sort has been forcefully challenged on textualist grounds by John Manning. See generally John F. Manning, Separation of Powers as Ordinary Interpretation, 124 Harv. L. Rev. 1939 (2011). As Manning acknowledges, however, modern academics and judges routinely conceptualize the separation of powers in general, trans-substantive terms. Id. at 1942-44,195071. This Article further follows convention in declining to draw any sharp distinction between the principle of separation of powers and the principle of checks and balances or the dispersal of power. Cf. Jeremy Waldron, Essay, Separation of Powers in Thought and Practice?, 54 B.C. L. Rev. 433,459-66 (2013) (questioning the common conflation of these principles).

Not everyone agrees that we are living in an Age of Dysfunction. See infra Part II.C.

(24.) See Richard H. Pildes, Why the Center Does Not Hold: The Causes of Hyperpolarized Democracy in America, 99 Calif. L. Rev. 273, 276 (2011). To be clear, constitutional countermeasures and constitutional conventions are both major subjects, which deserve study regardless of whether we have entered a period of protracted government failure. The possibility that we have done so simply raises the stakes.

(29.) I supply many more examples of general versus conditional self-help from the interbranch context infra Part I.E.

(30.) Epstein, supra note 27, at 3.

(31.) Note that even under this expansive understanding of interbranch self-help, a lawsuit brought by Congress or the President would not count, regardless of whether the mere bringing of the suit could have redressive or deterrent effects. Nor would it count if either branch sought to secure a formal constitutional amendment, inasmuch as this strategy requires ratification by state legislatures or conventions to be legally effective. See U.S. Const. art. V.

(32.) I use the more generic terms "wrong" and "impermissible," rather than "lawbreaking" and "unlawful," because I mean to capture behaviors that could be seen as violations of either convention or law. See generally infra Part II.

(33.) See, e.g., Douglas Ivor Brandon et al., Special Project, Self-Help: Extrajudicial Rights, Privileges and Remedies in Contemporary American Society, 37 Vand. L. Rev. 845, 911-37 (1984) (reviewing cases on "self-help in commercial transactions," including numerous corporate transactions).

(34.) Cf. Posner & Vermeule, supra note 21, at 997-98 (explaining and defending this "simplifying assumption" in their study of interbranch conflict). The text of the Constitution largely speaks of the branches' "powers," rather than of remedies or defenses. See U.S. Const, arts. I-III. Self-help devices can take many forms, however, including codified rights or authorizations to act in a certain manner or to change a certain legal relationship--for instance, a secured party's right to take repossession upon default under the Uniform Commercial Code. U.C.C. [section] 9-609 (2002).

(35.) See infra notes 351-358, 372-375 and accompanying text.

(37.) In a recent article, British legal theorist Nicholas Barber divides institutional "self-defense" mechanisms into positive and negative variants. N.W. Barber, Self-Defence for Institutions, 71 Cambridge L.J. 558 (2013). The former "give institutions a power that they can use against other constitutional bodies," id. at 561, whereas the latter provide some measure of insulation from external threats, id. at 560-61. Examples of the latter include official immunities from criminal or civil liability, salary protections, and limitations on judicial review. Id. Several of the positive mechanisms identified by Barber overlap with the tools catalogued in this Part. By contrast, it is hard to see how many of his negative mechanisms could qualify as tools of interbranch self-help, even under the broader definition above. While these mechanisms may serve to ensure that certain threats to an institution never arise, by design most do not seem capable of preventing imminent wrongs or redressing wrongs that have in fact occurred.

(38.) U.S. CONST, art. I, [section] 6, cl. 1 ("[F]or any speech or debate in either House, [Senators and Representatives] shall not be questioned in any other place."); see Josh Chafetz, Congress's Constitution, 160 U. Pa. L. Rev. 715, 743-44 (2012) (explaining that, whatever else it protects, the Speech or Debate Clause "clear[ly]" ensures that "members of Congress cannot be held criminally or civilly liable for speech acts ... performed in Congress").

(39.) See Walter J. Oleszek, Congressional Procedures and the Policy Process 259 (9th ed. 2014) ("Senators regularly place holds on diplomatic and other nominations to extract concessions from ... federal agencies.").

(40.) See William P. Marshall, The Limits on Congress's Authority to Investigate the President, 2004 U. III. L. Rev. 781, 785-808 (describing the history and scope of Congress's power to investigate the executive branch and concluding that "any actual [legal] constraints" on this power "are difficult to discern").

(41.) For a recent example, see H.R. Res. 644, 113th Cong. (2014) (" [condemning and disapproving of the Obama administration's failure to comply with the lawful statutory requirement to notify Congress before releasing individuals detained at United States Naval Station, Guantanamo Bay, Cuba").

(42.) Joint resolutions are generally subject to the Constitution's bicameralism and presentment requirements, U.S. CONST, art. I, [section] 7, cl. 3, whereas unicameral and concurrent resolutions are not. Congressional supermajorities may, of course, override presidential vetoes. Id.

(43.) See generally Todd Garvey & Alissa M. Dolan, Cong. Research Serv., RL34097, Congress's Contempt Power and the Enforcement of Congressional Subpoenas: Law, History, Practice, and Procedure (2012). The contempt power has long been understood to include the power to arrest, reprimand, and imprison contemnors without the aid of the executive branch. See Josh Chafetz, Executive Branch Contempt of Congress, 76 U. Chi. L. Rev. 1083,1127-48 (2009).

(44.) See Chafetz, supra note 38, at 725-35 (reviewing the "power of the purse," including "zeroing-out" strategies). Within the executive branch, only the President's compensation is expressly protected by the Constitution. U.S. Const, art. II, [section] 1, cl. 7.

(45.) U.S. Const, art. I, [section] 2, cl. 5; id. [section] 3, els. 6-7.

(46.) Id. art. III, [section] 1.

(47.) See United States v. Will, 449 U.S. 200, 228-29 (1980) (holding that Article III's Compensation Clause prohibits only the repeal of salary increases and cost-of-living adjustments that have already vested).

(48.) Cf. Eugenia F. Toma, A Contractual Model of the Voting Behavior of the Supreme Court: The Role of the Chief Justice, 16 Int'l Rev. L. &ECON. 433 (1996) (reporting evidence linking Supreme Court voting behavior to congressional budget allocations).

(49.) Congress clearly has substantial powers in this regard, see U.S. CONST, art. III, [section] 1', id. [section] 2, cl. 2, although their limits have been the subject of intense debate. See William A. Fletcher, Lecture, Congressional Pouter over the Jurisdiction of Federal Courts: The Meaning of the Word "All" in Article III, 59 DUKE L.J. 929, 953 n.98 (2010) (listing important works on jurisdiction-stripping).

(50.) While it may be unthinkable today that Congress would pursue any strong version of this strategy against the Supreme Court, in light of the failure of President Franklin Roosevelt's "court-packing" plan, conventional wisdom continues to view the strategy as legally available. See Akhil Reed Amar, America's Unwritten Constitution 355 (2012) ("A strong case can be made that the written Constitution was designed precisely to allow Congress to rein in or resize a Court that Congress believes has acted improperly."); Richard H. Pildes, Is the Supreme Court a "Majoritarian" Institution?, 2010 Sup. Ct. Rev. 103, 129-33 (discussing the backlash against and legacy of Roosevelt's plan, notwithstanding that "Congress has always had the power to decide the size of the Court").

(51.) At a minimum, federal judges may be removed from office by impeachment in the House and conviction (with a two-thirds vote) in the Senate for "Treason, Bribery, or other high

Crimes and Misdemeanors." U.S. CONST, art. II, [section] 4; see also id. art. III, [section] 1 (conditioning judicial tenure protection on "good Behaviour"). Some constitutional scholars believe that federal judges may also be removed for lesser offenses, by methods other than impeachment. See, e.g., Saikrishna Prakash & Steven D. Smith, How to Remove a Federal Judge, 116 Yale L.J. 72 (2006).

(52.) 491 U.S. 397 (1989).

(53.) United States v. Eichman, 496 U.S. 310, 315 (1990). The Court declined the invitation and likewise invalidated the federal statute as applied. Id. at 315-19. If this statute were in fact a political stunt rather than a genuine effort to remedy the Court's error, Congress's efforts may still have amounted to (at most) a form of symbolic redress.

(54.) 462 U.S. 919 (1983). Legislative vetoes are devices through which Congress delegates authority to the executive branch on the condition that Congress retain the right to block specific implementations of that authority without having to pass another law.

(55.) See Louis Fisher, The Legislative Veto: Invalidated, It Survives, 56 Law & CONTEMP. Probs. 273, 288-91 (1993)

Bar Ass'n (July 9, 1985), reprinted in Originalism: A Quarter-Century of Debate 47, 50-54 (Steven G. Calabresi ed., 2007) (criticizing the Court's recent decisions on federalism, criminal law, and religion and urging adoption of a "jurisprudence of original intention").

(57.) The text of the Constitution gives the President not just an option but a duty to make periodic recommendations to Congress. U.S. Const, art. II, [section] 3.

(60.) More specifically, President Jefferson terminated all ongoing Sedition Act prosecutions and pardoned those who had been convicted under the Act. See Saikrishna Bangalore Prakash, The Executive's Duty to Disregard Unconstitutional Laws, 96 Geo. L.J. 1613, 1664-69 (2008). But cf. Leonard W.

(68.) See Meltzer, supra note 61, at 1191 ("[M]ost commentators ... concede that the president may not defy a judicial order to comply with (the court's interpretation of) the Constitution ...."). While few commentators endorse an executive power to defy judicial judgments, a much larger group of "departmentalists" endorse an executive power to disregard judicial interpretations of the Constitution in other contexts. See Frederick Schauer, The Supreme Court, 2005 Term--Foreword: The Court's Agenda--and the Nation's, 120 Harv. L. Rev. 4, 50 n.174 (2006) (collecting sources).

(72.) See David J. Barron & Martin S. Lederman, The Commander in Chief at the Lowest Ebb--Framing the Problem, Doctrine, and Original Understanding, 121 Harv. L. Rev. 689, 704-11 (2008) (detailing examples); see also id. at 712-20 (identifying structural and historical reasons to expect that "lowest ebb" questions will remain prominent).

(73.) See United States v. Windsor, 133 S. Ct. 2675, 2683-84 (2013). The attacks of September 11, 2001 and the struggle against terrorism have further highlighted the question of presidential emergency powers. Since at least as far back as John Locke, a strain of constitutional theory has envisioned the executive as possessing an indefeasible "prerogative power" to bypass legal constraints in the service of a greater good, such as the security of the nation. See JOHN Locke, The Second Treatise of Government [section] 160, in Two Treatises of Government 265, 37s (Peter Laslett ed., Cambridge Univ. Press 1988) (1690) (describing an executive "Power to act according to discretion, for the publick good, without the prescription of the Law, and sometimes even against it"). See generally Extra-Legal POWER AND LEGITIMACY: PERSPECTIVES on Prerogative (Clement Fatovic & Benjamin A. Kleinerman eds., 2013). It is doubtful that any exercise of the prerogative power would deserve to be seen as self-help, inasmuch as the latter entails the assertedly lawful remedying of a wrong, whereas the former entails the admittedly extralegal pursuit of some higher end. Regardless, it is important to appreciate that presidential self-help is a much broader, and more quotidian, phenomenon. With or without an emergency justification, Presidents have numerous tools with which to resist Congress and to submit that the wrongfulness of Congress's actions constitutionally authorizes, even compels, them to do so.

(74.) See Trevor W. Morrison, Constitutional Avoidance in the Executive Branch, 106 COLUM. L. Rev. 1189,1218 (2006) (observing that "the avoidance canon appears fairly often in the work of at least some executive components").

(75.) See Zachary S. Price, Enforcement Discretion and Executive Duty, 67 Vand. L. Rev. 671, 671 (2014) (detailing and critiquing the modern presidential practice of "claim [ing] wide-ranging authority to decline enforcement of federal laws").

(76.) See generally Frederick Schauer, Official Obedience and the Politics of Defining "Law," 86 S. CAL. L. Rev. 1165, 1183-87 (2013) (describing jurisprudential "strategies of reconciliation" that officials may employ to avoid acknowledging illegality).

(77.) While in theory Congress could employ similar reasoning to its own advantage, it rarely has occasion to do so because its enumerated powers vis-a-vis the President are already so substantial. Cf. Saikrishna Bangalore Prakash, A Critical Comment on the Constitutionality of Executive Privilege, 83 Minn. L. Rev. 1143, 1146 (1999) (explaining that "for the most part, the President relies upon Congress for the indispensable, necessary, and merely useful means of executing his constitutional powers").

(78.) See Letter from President Theodore Roosevelt to Joseph Bucklin Bishop (Mar. 23, 1905), quoted in W. Stull Holt, Treaties Defeated by the Senate: A Study of the Struggle Between President and Senate over the Conduct of Foreign Relations 221-22 (1933); see generally Holt, supra, at 212-29 (discussing this episode). A modus vivendi is a "temporary, provisional arrangement concluded between subjects of international law." Black's Law Dictionary, supra note 1, at 1096.

To be sure, a number of commentators have sharply criticized the legal moves sketched in the main text. There are some who insist that the President must enforce and defend all duly enacted laws, see, e.g., Raoul Berger, Executive Privilege: A Constitutional Myth 306 (1974); Eugene Gressman, Take Care, Mr. President, 64 N.C. L. Rev. 381 (1986); some who suggest that the canon of constitutional avoidance has no place in executive branch lawyering, see, e.g., Jerry L. Mashaw, Norms, Practices, and the Paradox of Deference: A Preliminary Inquiry into Agency Statutory Interpretation, 57 Admin. L. Rev. 501, 507-08 (2005); H. Jefferson Powell, The Executive and the Avoidance Canon, 81 IND. L.J. 1313 (2006); and some who advocate highly formalistic approaches to separation-of-powers questions, see, e.g., Martin H. Redish, The Constitution as Political Structure 99-134 (1995); Gary Lawson, Prolegomenon to Any Future Administrative Law Course: Separation of Powers and the Transcendental Deduction, 49 ST. LOUIS U. L.J. 885, 887 (2005). Such uncompromising positions appear to be on the decline these days. Many constitutional scholars now believe that Presidents may occasionally defy Congress through means other than vetoes, pardons, and rhetoric, and that functional and historical factors have a role to play in guiding these determinations. See William Baude, The Judgment Power, 96 GEO. L.J. 1807, 1810 & n.13 (2008) (collecting sources that reflect "the increasingly conventional wisdom that the President can or must disregard some or all laws that he independently believes to be unconstitutional"). Regardless of what scholars believe, these acts of defiance may be ineradicable inasmuch as Presidents take their political fortunes to depend upon perceptions of efficaciousness and accomplishment. Cf. Henry P. Monaghan, The Protective Power of the Presidency, 93 Colum. L. REV. 1, 8 (1993) ("Most Americans expect modern Presidents to provide solutions for every significant political, military, social, and economic problem. In the face of such demands, various organizational and legal categories possess little meaning for the President." (footnote omitted)); Curt Nichols, The Presidential Ranking Game: Critical Review and Some New Discoveries, 42 Presidential Stud. 275, 276 (2012) (discussing the significance for presidential legacies of being seen as "taking advantage of the opportunity to reorder the political regime").

(85.) See supra Part I.A.

(86.) To stress again: in characterizing presidential power in this way, I mean only to capture the prevailing view, not any timeless truth of constitutional law. The original understanding of the veto power, for instance, was focused mainly on protecting the presidency itself and did not necessarily encompass policy disagreements. See Charles L. Black, Jr., Some Thoughts on the Veto, 40 Law & Contemp. Probs. 87, 89-92 (1976). Over time, the veto power evolved from a conditional into a general self-help privilege.

(87.) U.S. Const, art. II, [section] 3. A minority of constitutional lawyers believe that the President violates the Take Care Clause any time she declines to enforce a duly enacted law, see supra note 78 and accompanying text, but most everyone agrees that she violates the Clause if she declines to enforce a concededly constitutional law. See, e.g., Issues Raised by Foreign Relations Authorization Bill, 14 Op. O.L.C. 37, 51 (1990) ("Obviously, the argument that the President's obligation to defend the Constitution authorizes him to refuse to enforce an unconstitutional statute does not authorize the President to refuse to enforce a statute he opposes for policy reasons.").

(88.) In cases in which a President signed the allegedly defective measure into law, that President might be seen as jointly or partially responsible for the wrongdoing.

(89.) On one specification, the canon of constitutional avoidance may be used only when the user determines that the avoided interpretation would be unconstitutional, while on another specification (more prevalent today) it may be used so long as the avoided interpretation is deemed to raise serious constitutional problems. See Morrison, supra note 74, at 1202-06. Regardless, the motivating premise is always that the potential illegality of Congress's instruction, as implemented, permits or requires the interpreter to privilege one available reading over another.

(90.) See supra note 51 (reciting the constitutional standard for impeachment).

(91.) See Garvey & Dolan, supra note 43, at 1 (discussing the basic substantive standard for a finding of contempt).

See, e.g., City of Boerne v. Flores, 521 U.S. 507, 519-20 (1997).

(112.) Confusingly, the term "constitutional conventions" may refer either to the norms under consideration here or to the special deliberative assemblies organized for the purpose of writing or revising a constitution, such as the Philadelphia Convention organized by the Framers in 1787. Needless to say, the referents are very different. Compounding semantic difficulties, international agreements are often described as "conventions"; the term "conventionalism" denotes a distinctive, context-sensitive approach in the philosophy of law and other disciplines, see generally Steven J. Burton, An Introduction to Law and Legal Reasoning 89-95 (3d ed. 2007); and the "conventionality thesis" describes a core claim of Hartian positivism regarding the possibility conditions of legal authority, see generally JULES L. Coleman, The Practice of Principle 74-102 (2001). It is the more workaday notion of constitutional conventions, familiar to any British lawyer, that is the subject of this Part.

(113.) By "constitutional self-help powers," I mean legal or political tools grounded in the written Constitution that may be used to resolve another branch's perceived wrongdoing without recourse to a third-party decisionmaker (as discussed supra Parts I.A-D). The congressional and presidential powers listed in the table are intended to reflect prevailing practices and to be representative, not necessarily exhaustive, of each category; recess appointments, for example, might be added to the presidential side of the ledger on some accounts.

(114.) I should stress, however, that it is not necessary to rely on the idea of "conventions," as such, to interrogate self-help. In considering the dynamics that generate and regulate interbranch retaliation, we could simply refer to all relevant legal, quasi-legal, and non-legal prohibitions as "norms." I deploy the idea of conventions on the belief that it can advance understanding, but the precise manner in which these prohibitions are classified is not crucial.

(115.) Adrian Vermeule, Conventions of Agency Independence, 113 COLUM. L. Rev. 1163, 1182 (2013). My thumbnail sketch of conventions draws heavily on Vermeule's fine overview. Id. at 118194. I will register one quibble. For the class of routine political practices that do not rise to the level of conventions, Vermeule's favored example is the annual "pardon" that Presidents issue to a turkey on Thanksgiving Day. This practice "is an observed regularity in political behavior," Vermeule remarks. "Yet no one believes that it is followed from a sense of political obligation, or believes that others believe so, and a breach of the practice would not produce any sanctions...." Id. at 1185; accord id. at 1193. This assertion is demonstrably false, because I myself so believe. Imagine if President Obama were to consider scrapping the turkey-pardon tradition next year. I assume his advisors would warn him of political repercussions that might follow--perhaps in the form of public disapproval, perhaps in the form of partisan insinuations of lack of patriotism or, worse yet, of vegetarian leanings (given that the tradition ultimately serves to validate the practice of eating turkeys). And so the President would stay the course. The annual turkey pardon may not be a constitutional convention, because too removed from the organization and dominion of government. See infra notes 117-119 and accompanying text. But it is a convention all right. Although the example is trivial in itself, it bears mention inasmuch as it points up the difficulty of identifying some conventions and suggests just how pervasive they may be.

(116.) As Jaconelli observes, "[t]he literaUire tends to examine only cursorily the nature of constitutional conventions, being concerned more with practical instances of what are taken... to be examples of the phenomenon...." Joseph Jaconelli, The Nature of Constitutional Convention, 19 Legal Stud. 24,24 (1999).

(117.) Geoffrey Marshall, Constitutional Conventions 1 (1984). In his well-known study of British constitutional conventions, Marshall argues that their "major purpose... is to give effect to the principles of governmental accountability that constitute the structure of responsible government." Id. at 18; see also id. at 210 ("Conventions have as their main general aim the effective working of the machinery of political accountability."). Marshall's account not only highlights the links among constitutional conventions, government efficacy, and political morality but also suggests a teleological view of the former.

(118.) Cf. Jaconelli, supra note 116, at 26, 45 (noting that the distinction between nonconstitutional and constitutional conventions "has been very largely ignored" and contending that the latter must have some "inter-institutional" or "inter-party" dimension).

Jon Elster, Unwritten Constitutional Norms 21 (Feb. 24, 2010) (unpublished manuscript), http://www.ucl.ac.uk/laws/jurisprudence/docs/2010/Elster24Feb2010.pdf [http://perma.cc /YPN8-764G] ("With virtually no exception, [constitutional conventions] regulate... the 'machinery of government,' that is, the relation between the main branches of government, their prerogatives, and the limitations on their powers. None of them address issues of individual rights, be they negative or positive, first, second or third generation.").

Rev. 645, 659 (1992); see also Peter W. Hogg, Constitutional Law of Canada 7 (5th ed. 2007) ("What conventions do is to prescribe the way in which legal powers shall be exercised."). In Dicey's formulation, constitutional conventions determine "the mode in which the several members of the sovereign ... should each exercise their discretionary authority." A.V. Dicey, Introduction to the Study of the Law of the Constitution 424 (8th ed. 1915).

(121.) It is now widely agreed that a judge may, at a minimum, look to conventions as context for the interpretation of statutes and common law rules that were developed with them in view. See Vermeule, supra note 115, at 1183-84.

(122.) Commonwealth theorists routinely characterize conventions as "non-legal" yet operating on some higher plane than other customs and practices. See Ian Loveland, Constitutional Law, Administrative Law, and Human Rights 262 (6th ed. 2012) (noting the standard view, traceable to Dicey, that in addition to constitutional conventions "there are also a set of non-legal constitutional rules inferior to conventions").

(123.) See Frederick Schauer, Authority and Authorities, 94 Va. L. Rev. 1931, 1935-40 (2008) (describing "the conventional wisdom" about legal authority and content-independence).

(124.) Cf. Vermeule, supra note 115, at 1184 (discussing the dimensions of "scope and weight"). There are many additional complexities lurking in this sketch. For instance, what exactly is the sense of obligation that officials must feel or the relationship they must hold toward a convention? Is the question whether a norm has the requisite obligatory force essentially empirical in nature, a function of the aggregate behaviors and beliefs of government actors, or is it determined at least in part by critical reason? Legal theorists have filled volumes debating such issues. Cf. Richard H. McAdams, Conventions and Norms: Philosophical Aspects, in 4 International Encyclopedia of the Social & Behavioral Sciences 2735 (Neil J. Smelser & Paul B. Baltes eds., 2001) (reviewing broader social science debates over how best to define and explain conventions). For purposes of this Article, it is not clear that anything important hangs on these jurisprudential niceties, or on the precise lines separating constitutional conventions from politics or law, and my aim will be to sidestep them to the extent possible. The Article's contribution to the literature on conventions lies not in any direct intervention, but in identifying and developing some of the links with self-help and the separation of powers.

(130.) See generally Vermeule, supra note 115 (exploring the role of conventions in the administrative state); Whittington, supra note 125 (exploring the relationship between the United States' written and unwritten constitutions). Other works have drawn on this literature in more limited ways. See, e.g., Bradley & Morrison, supra note 95, at 1128-30. In his influential study of our "constitution outside the constitution," Ernest Young takes the English model as a jumping-off point but quickly "place[s] to one side the role of 'conventions.'" Ernest A. Young, The Constitution Outside the Constitution, 117 Yale L.J. 408, 410 n.2 (2007). The most extended treatment of U.S. constitutional conventions in recent years, by James G. Wilson, supra note 120, has had only a modest impact. Cf. Elster, supra note 119, at 15 n.30 (stating that the contribution of Wilson's article "is entirely vitiated by the confusion between descriptive, explanatory and normative aims").

(131.) Whittington, supra note 125, at 1854. See generally Keith E. Whittington, Constitutional Construction: Divided Powers and Constitutional Meaning (1999). For a rigorous development of this distinction, see Lawrence B. Solum, The Interpretation-Construction Distinction, 27 Const. Comment. 95 (2010). Whether and how the interpretation-construction distinction translates to Commonwealth jurisdictions strikes me as a question that deserves greater attention.

(134.) Dicey, supra note 120, at 22 (describing " [constitutional law, as the term is used in England"); see also Primus, supra note 23, at 1127 (describing the small-c constitution as the "set of rules and norms and institutions that guide the process of government").

(136.) This subject is surprisingly understudied, even within the small literature on American constitutional conventions. Vermeule's recent article, for instance, focuses on conventions within the executive branch, Vermeule, supra note 115, while Whittington's focuses on higher-level theoretical concerns, Whittington, supra note 12s. Conventions go unmentioned in the principal law school casebook on the separation of powers. See Peter M. Shane & Harold H. Bruff, Separation of Powers Law: Cases and Materials (3d ed. 2011).

More productive lines of inquiry, it seems to me, would ask how all such conventions are operationalized and enforced, why government officials would or should comply with them, and whether relevant doctrines are well-suited to securing important public values.

(163.) The Guarantee Clause provides that "[t]he United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion ...."

White, 74 U.S. (7 Wall.) 700, 729-30 (1868), and that judicial decisions deeming the clause to be nonjusticiable, such as Luther v. Borden, 48 U.S. 1 (1849), have "effectively rendered [it] a nullity." Erwin Chemerinsky, Cases Under the Guarantee Clause Should Be Justiciable, 65 U. Colo. L. Rev. 849, 850 (1994).

Thus, after the House of Representatives voted in June 2012 to hold Attorney General Holder in contempt for refusing to turn over documents relating to Operation Fast and Furious, see H.R. Res. 711, 112th Cong. (2012), the House promptly abjured further self-help and sought judicial enforcement of the committee's subpoena. See Complaint, House Comm, on Oversight and Gov't Reform v. Holder, No. 1:12-cv-1332 (D.D.C. Aug. 13, 2012). More dramatically, the House of Representatives recently authorized Speaker John Boehner to initiate a lawsuit against President Obama and other executive branch officials for the alleged failure to implement the Affordable Care Act "in a manner consistent with ... the U.S. Constitution and federal laws...."

(208.) Stephenson acknowledges that the historical practice of requiring a Senate vote cuts strongly against his proposal. Id. at 967-68. In fact, the problem is even deeper, because in this case we have a practice that is not only longstanding but also one whose earliest iterations may be seen as "liquidating"--and fixing for all time--the meaning of the Advice and Consent Clause. See Caleb Nelson, Originalism and Interpretive Conventions, 70 U. Chi. L. Rev. 519, 525-29 (2003) (explaining the "liquidation" process through which many of the Founders expected constitutional ambiguities to be resolved).

F. 122, 124 (2013) (speculating that Senate obstructionism could, in combination with other factors, "eventually produce so much pent-up demand for reform of the appointments process that the President offers some radical reinterpretation of the Constitution, one that gives him substantially increased discretion over appointments").

A/CN.4/SER.A/2001/Add.1 (Part 2) [hereinafter ILC Articles and Commentary] (explaining that the term "reprisals" has become synonymous with "belligerent reprisals"). Reprisals are regulated by the U.N. Charter and by international humanitarian law. See generally Ashley S. Deeks, "Unwilling or Unable": Toward a Normative Framework for Extraterritorial Self-Defense, 52 Va. J. Int'l L. 483 (2012) (summarizing relevant law and exploring circumstances in which states may use force in self-defense against nonstate groups within the territory of other states that are "unable or unwilling" to suppress the threat posed by those groups). Within the U.S. system, both the right of national self-defense and the role of the U.N. Security Council in promoting international peace and security have been invoked in support of presidential claims of inherent constitutional authority to order the use of military force. See, e.g., Memorandum from Caroline D. Krass, Principal Deputy Assistant Att'y Gen., Office of Legal Counsel, Dep't of Justice, to Att'y Gen. Eric Holder 12 (Apr. 1, 2011). In these arguments, the international regime of self-help intersects with, and potentially alters, the domestic balance of powers.

Over the past two decades, a vigorous debate has erupted over whether the U.N. Charter's prohibition on the use of force is or should be further qualified with an exception for humanitarian intervention, often referred to as a "responsibility to protect" or "R2P." See generally Int'l Comm'n on Intervention & State Sovereignty, The Responsibility to Protect, at XI (2001) (introducing the term "responsibility to protect" and advocating that it trump the principle of nonintervention "[w]here a population is suffering serious harm, as a result of internal war, insurgency, repression or state failure, and the state in question is unwilling or unable to halt or avert it"); Int'l Coalition for the Responsibility to Protect, http://www.responsibilitytoprotect.org [http://perma.cc/KCL6-BN7B] (collecting resources on R2P). The R2P debate was prompted, in part, by NATO's 1999 intervention in Kosovo, which was taken without authorization from the U.N. Security Council or a clear self-defense rationale. At the time, many strained to defend NATO's action as nonetheless legal, see, e.g., Abraham D. Sofaer, International Law and Kosovo, 36 Stan. J. Int'lL. 1, 3-4, 12-21 (2000); as illegal but legitimate, see, e.g., Antonio Cassese, Ex Iniuria Ius Oritur: Are

We Moving Towards International Legitimation of Forcible Humanitarian Countermeasures in the World Community?, 10 EUR. J. Int'l L. 23 (1999); or as illegal but excusable, see Jane Stromseth, Rethinking Humanitarian Intervention: The Case for Incremental Change, in Humanitarian Intervention 232,243-44 (J.L.

See Elena Katselli Proukaki, The Problem of Enforcement in International Law 69-71 (2010); see also Denis Alland, The Definition of Countermeasures, in The Law OF INTERNATIONAL RESPONSIBILITY 1127 (James Crawford et al. eds., 2010) (discussing definitional nuances).

The United States registered a number of objections to the Articles on countermeasures when in draft, generally on the view that their rules were too demanding. See Sean D. Murphy, Contemporary Practice of the United States Relating to International Law, 95 Am. J. Int'l L. 626, 626-28 (2001) (summarizing the U.S. government's March 1, 2001 written comments to the ILC).

(271.) See, e.g., Restatement (Second) of Torts [section][section] 101,103 (1965). Or to use Badawi's favored examples, creditors are allowed to repossess collateral without resort to judicial process, including through trespass, so long as they do not create a breach of peace in so doing, whereas landlords in most states are no longer allowed to use self-help repossession. See Badawi, supra note 215, at 2-4. In the former case, breaches tend to be "rather straightforward" because "the contracts between creditors and debtors that govern personal property ... impose few duties on the creditor": when the debtor misses payments, default has occurred. Id. at 4. By contrast, breaches of real property leases tend to involve greater legal complexity because of reciprocal duties such as the landlord's responsibility to repair and maintain the premises. Id.

(272.) See generally Posner & Vermeule, supra note 21; Tushnet, supra note 22. Neither Tushnet nor Posner and Vermeule state this assumption. I infer it from, among other things, the fact that the authors devote significant attention to the ways in which hardball and showdowns may create new precedents that constrain future actors, without mentioning the possibility that hardball and showdowns might themselves be constrained by a relatively resilient set of legal or quasi-legal norms.

(273.) Or, at least, no such principles are identified. Cf. Posner & Vermeule, supra note 21, at 99798 (defining showdowns to require an absence of compromise); Tushnet, supra note 22, at 531 ("The winner of constitutional hardball takes everything, and the loser loses everything."). One reason why Tushnet discounts norms of conflict management may be that he is focused on instances in which politicians believe that "permanent control ... of the entire government" is up for grabs. Id. His theory of hardball does not purport to supply a general lens through which to view intragovernmental legal struggle, so much as an account of how constitutional law is practiced by partisans during extraordinary periods of transformation. See id. at 531-33, 547; see also Mark Tushnet, Response, 26 Quinnipiac L. Rev. 727, 732 (2008) ("For me, constitutional hardball is--definitionally--a transitional phenomenon that occurs when one side sees an opportunity to shift the constitutional order ....").

(277.) It is the substance of these charges, not the precise wording, that matters here. While the term "proportionality" may at present have a European flavor, American lawyers are comfortable with concepts like reasonableness, tailoring, and fit, which get at the same basic idea.

Devins & Prakash, supra note 63, at 535. This critique may be valid on its own terms, but it slights the practical value, for the system of constitutional enforcement as a whole, of (self-)imposing limiting principles on the most extreme self-help tools.

(327.) I do not mean to deny the heuristic value of those sports metaphors, or to suggest that additional work on the origins and empirics of intragovernmental self-help would not be valuable. Scholars could, for instance, draw on rational choice theory to develop testable hypotheses regarding how such self-help occurs. Here are two. It seems plausible that the principal forms of conditional executive self-help described in Part I (nonenforcement, nondefense, constitutional avoidance, and executive privilege) tend to increase during periods of divided government, second presidential terms, and wartime. It also seems plausible that comparatively opaque strategies of executive self-help, such as creative legal interpretation and constitutional avoidance, are preferred to comparatively salient strategies, such as the avowed nonenforcement of statutes, when the underlying congressional policy remains popular.

That is to say, the Solicitor General's remarks at oral argument evoked, but did not do the hard work of detailing or theorizing, both the claim that current levels of Senate intransigence were sufficiently problematic to trigger a conditional self-help power and the claim that the recess appointment in question was an appropriately limited exercise of that power.

See Steve Coll, The Senator vs. the C.I.A., New Yorker, Mar. 24, 2014, http://www.newyorker.com/talk/comment/2014/03/24 /140324taco_talk_coll [http://perma.cc/7ZTU-SWWS]; Darren Samuel Sohn, Dianne Feinstein-CIA Feud Enters Uncharted Territory, Politico (Mar. 23, 2014), http://www.politico.com/story/2014/03/dianne-feinstein-cia- feud-104927.html [http://perma.cc/J8B6-WS2N].

(353.) Cf. Posner & Vermeule, supra note 21, at 1036-37 (noting that the American constitutional system "displays both separation of powers and parties in a complicated interaction" and emphasizing that the "mechanisms that cause partisan interests to trump, or be trumped by, institutional interests are manifold and highly contextual"). Partisan self-help is thus but one (large and internally diverse) category of interbranch self-help, and vice versa.

(354.) It would take another paper to elaborate the details, but as this Article's examples suggest, partisan dynamics inspire certain retaliatory efforts while suffocating others; support certain norms of moderation and fair play while subverting others; generate an ever-shifting array of cross-branch alliances; and perhaps also foster different underlying orientations to constitutional unilateralism, duty, and convention.

(355.) See, e.g., supra Part II.C (discussing Senate Republicans' and President Obama's self-help moves against one another, in a period in which Democrats controlled both the Senate and the White House).

(356.) Cf. Levinson & Pildes, supra note 351, at 2316 (arguing that "[t]he greatest threat to constitutional law's... normative goals for[] separation of powers comes when government is unified and interbranch political dynamics shift from competitive to cooperative").

(357.) Bradley & Morrison, supra note 157, at 414-15; see also id. at 438-47 (describing additional factors that support this belief); William G. Howell, Power Without Persuasion: The Politics of Direct Presidential Action 178 (2003) (contending that, with the notable exception of the budget process, "Congress rarely can mount an effective and timely response to the President").

(358.) In his Response to this Article, William Marshall warns that this concern is very severe indeed, as Presidents are in a "far better position" than Congress "to take effective advantage" of self-help and are liable to do so in destructive ways. See William P. Marshall, Warning!: Self-Help and the Presidency, 124 Yale L.J. F. (forthcoming 2014). Marshall's forceful argument provides a basis for concluding that it would be desirable to strengthen or at least to reaffirm the existing limits on executive self-help. I have a lot of sympathy for this position. Cf. infra notes 364-370 and accompanying text (discussing possible reforms to rein in the executive). Marshall's argument does not, in my view, provide any basis for denying that such self-help is in fact occurring, as a realistic, descriptive matter, or for dismissing the very idea of a self-help framework, as an analytic or prescriptive matter.

(359.) Cf. supra Part II.C (discussing popular and presidential responses to recent breaches of constitutional conventions, including several cases in which the underlying convention appears to have been restored).

(360.) The general theory of the second best supports the point. This theory "holds that where it is not possible to satisfy all the conditions necessary for an economic system to reach an overall optimum, it is not generally desirable to satisfy as many of those conditions as possible." Adrian Vermeule, The System of the Constitution 29 (2011) (citing R.G. Lipsey & Kelvin Lancaster, The General Theory of Second Best, 24 Rev. Econ. Stud. 11, 11-12 (1956)). As Vermeule has shown, the theory's basic insight can be deployed to undermine the assumption that when one actor in government--say, Congress--departs from some normative benchmark--as by violating the Constitution--the best approach is for every other actor to continue to conform their conduct to the benchmark. See id. at 87-94. To the contrary, a response that includes non-ideal behavior by other actors--such as otherwise unacceptable presidential retaliation--may well move the overall system as close as possible to the ideal state of everyone's always behaving lawfully.

(361.) See supra notes 250-251 and accompanying text.

(362.) See Bederman, supra note 235, at 826.

(363.) Michel Foucault, Discipline and Punish 82-89, 257-92 (Alan Sheridan trans., Vintage Books 2d ed. 1995) (1977). The French term is illegalismes, a neologism that better captures the ambivalent character of these practices.

(364.) At common law, the rules were far more favorable to landlords, who could not only unilaterally repossess leased premises but also use the privilege of distraint to seize tenants' personal property in satisfaction of overdue rent. Most jurisdictions now prohibit both forms of self-help. See Brandon et al., supra note 33, at 937-41.

(365.) See, e.g., William P. Marshall, Essay, Eleven Reasons Why Presidential Power Inevitably Expands and Why It Matters, 88 B.U. L. Rev. 505 passim (2008) (describing factors driving an "exponential[]" expansion in presidential power since the Founding and a resulting "constitutional imbalance").

(366.) Hubert Lesaffre, Circumstances Precluding Wrongfulness in the ILC Articles on State Responsibility: Countermeasures, in The Law of International Responsibility, supra note 237, at 469, 470.

(367.) See supra notes 351-358 and accompanying text (discussing the concern that the executive branch is better equipped than Congress to engage in the systematic practice of self-help).

(368.) See generally Vincent Blasi, The Pathological Perspective and the First Amendment, 85 Colum. L. Rev. 449 (1985). Blasi expressly limited his argument about fashioning constitutional doctrines "for the worst of times" to the First Amendment context. Id. at 450.

(369.) These ideas are not fanciful. The latter is already prefigured by modern OLC doctrine, see supra notes 305-308 and accompanying text, and the former has been advocated by leading scholars such as Jerry Mashaw and H. Jefferson Powell, see supra note 78 and accompanying text. "If the executive were to disavow use of the avoidance canon, or if the rest of us were to reject that use," Powell contends, "the benefits to constitutional law and American democracy would be immense." Powell, supra note 78, at 1317.

(370.) See supra notes 248-249 and accompanying text (summarizing the WTO approach to countermeasures).

(371.) Cf. Vermeule, supra note 115, at 1189 ("Internalization may of course arise through rational argumentation about political morality.").

(372.) Cf. supra notes 351-360 and accompanying text (discussing the relationship between partisanship and self-help).

(373.) See, e.g., Oleszek, supra note 39, at 422 ("Congress's informal procedures and practices are often as important as its formal rules.").

(376.) See Paul Finkelman, Turning Losers into Winners: What Can We Learn, if Anything, from the Antifederalists?, 79 Tex. L. Rev. 849, 892 (2001) (book review) (observing that late nineteenth-century secessionists resurrected the tradition of early nineteenth-century nullificationists and "ultimately replaced the antifederalists as the greatest political losers in American political history").

(377.) Jessica Bulman-Pozen & Heather K. Gerken, Essay, Uncooperative Federalism, 118 Yale L.J. 1256, 1259 (2009); see also Abbe R. Gluck, Essay, Intrastatutory Federalism and Statutory Interpretation: State Implementation of Federal Law in Health Reform and Beyond, 121 Yale L.J. 534, 572 (2011) (noting "the potential for some states to be less eager, less effective, or even rebellious implementers of federal law").

(378.) Jessica Bulman-Pozen, Partisan Federalism, 127 Harv. L. Rev. 1077, 1080-82, 1096-1108 (2014). On Bulman-Pozen's conception, it is the political parties, rather than distinctive state interests, that drive these confrontations; states are not so much the authors of autonomous resistance as they are the vehicles of partisan self-help.

(379.) See, e.g., Bulman-Pozen & Gerken, supra note 377, at 1276-78 (highlighting various states' efforts to "tak[e] advantage of a regulatory gap" with regard to the Clean Air Act).

(380.) Arizona v. United States, 132 S. Ct. 2492, 2521 (2012) (Scalia, J., concurring in part and dissenting in part). See generally Pratheepan Gulasekaram & S. Karthick Ramakrishnan, Immigration Federalism: A Reappraisal, 88 N.Y.U. L. Rev. 2074, 2089 (2013) (describing and critiquing "the early twenty-first century's resurgence of subfederal immigration regulation").

(381.) Or at least, they are pervasive on a broad understanding of what counts as intragovernmental self-help. See supra Parts I.A, I.E (reviewing alternative definitions of self-help).
