Law enforcement as political question.

2. Case-Specific Nonenforcement

These manageability problems apply with particular force to case-specific nonenforcement decisions, as opposed to announced general policies. (182) Although Heckler itself was ambiguous about the meaning of nonenforcement and the scope of decisions subject to its unreviewability presumption, some lower courts have understood the decision to apply only to case-specific--"single shot"--nonenforcement, as opposed to general agency policies. (183) Even some courts articulating this distinction have not applied it consistently. (184) Furthermore, although Heckler itself was a "single shot" decision in the sense that it involved denial of a specific petition for enforcement, the petition related to a general class of cases and the agency's decision announced a general approach of nonenforcement with respect to that class. (185) All that said, the basic insight that Heckler carries greatest force with respect to "single shot" nonenforcement is sound. (186)

Confronted with nonenforcement in a particular case, courts cannot readily judge the agency's opportunity costs in pursuing that case rather than another. Indeed, even the agency may not be aware of the full set of potentially comparable cases that could be developed with adequate investigation. Courts likewise cannot assess the agency's likelihood of success as competently as the agency can; nor can they objectively judge the relative importance of the case within the agency's overall responsibilities.

Some critics of Heckler have argued that arbitrariness review of the sort courts normally perform with respect to discretionary agency action should nevertheless apply equally to administrative nonenforcement. (187) On this view, at least insofar as the agency has memorialized its nonenforcement decision in some form (such as through denial of a petition for enforcement), a court conducting judicial review under the APA could set aside the agency's decision if the agency failed adequately to consider its decision's implications, made some evident mistake in its perception of the facts or law, or appeared to rely on arbitrary or impermissible reasons rather than reasons rooted in statutory or regulatory policy. (188) While this proposal in principle might help ensure consistency and fairness in agency enforcement practices, it carries at least two fatal drawbacks.

The first is that requiring a decisionmaking process sufficient to support such review would itself squander enforcement resources while achieving little commensurate benefit in terms of statutory compliance. As Eric Biber has argued, agencies typically "must make many informal and quick judgments on a regular basis" about "whether to enforce a regulation or statute against a private party." (189) "In such situations, the possibility of judicial review would force the agency to make those decisions in a more formal and regularized manner, require a vast increase in resources for the decisionmaking process, and sharply circumscribe its ability to address other issues or problems." (190) In contrast, the principal asserted benefit of judicial review would be to mitigate risks of corruption, improper bias, or legal error. (191) But absent any particular reason to suspect such improper motivations, the benefits of reducing this risk may not be worth the costs in terms of reducing administrative efficiency and overall enforcement potential. (192)

At any rate, these proposals carry the additional problem that requiring reasoned elaboration of agency enforcement practice could itself be counterproductive with respect to the ultimate goal of faithful execution--ensuring compliance with substantive law. An articulated enforcement practice is one that regulated parties can evade. For this reason, agencies often keep enforcement priorities secret or even avoid articulating them formally. (193) To be sure, there may also be benefits to announcing an agency's priorities; I address the benefits and costs of doing so below. (194) But interpreting the APA to require such reason-giving across the board would unduly collapse the distinction between law and its enforcement. Advocates of this view, indeed, recognize that it would require articulation of general enforcement policies independent of substantive legal requirements; insofar as the substantive law itself fails to prescribe any focus of agency effort, the agency would need to articulate such priorities itself and then justify each enforcement proceeding in their terms. (195) But to the extent such policies bind the agency (either practically or legally), they may effectively replace applicable substantive law as the governing law for regulated parties. (196)

For all these reasons, interpreting the APA to categorically bar review of such decisions comports with more general, constitutionally informed ideas about the relative institutional competence of courts and executive agencies--whether or not the effective freedom given to executive officials by this judicial passivity accords with any appropriate conception of how executive officials should independently understand their responsibility. As Heckler recognizes, if Congress specifically provides for review or imposes a specific mandate of enforcement, then the problem of judicial unmanageability disappears. The court then need not consider the imponderable tradeoffs involved in not proceeding in the particular case; Congress has effectively established an enforcement priority for the agency, and the court need only review the agency's decision in the particular case. But without such congressional direction the court would have no objective basis for requiring enforcement in the particular case. (197)

3. General Policies

Concerns about judicial unmanageability apply somewhat differently to publicly disclosed general nonenforcement policies. To begin with, insofar as it alerts regulated parties to agency enforcement plans, any such policy carries costs in terms of statutory compliance that more ad hoc or indefinite or undisclosed nonenforcement practices do not. Articulating a general policy thus moves one step beyond the inevitable enforcement discretion that results from resource constraints and practical challenges. To be sure, the agency might well have achieved the same pattern of results through case-by-case nonenforcement without articulation of a general policy. In principle, moreover, the agency might always change its policy without notice and resume enforcement. (198) Even so, insofar as the policy provides advance notice of the agency's intentions, it may carry costs to compliance with substantive law that nonenforcement in any particular case does not. By the same token, setting aside the policy through judicial review might vindicate the primacy of the substantive law simply by restoring that law's deterrent effect, even if the agency never ultimately pursues enforcement in any particular case. Furthermore, the very choice to articulate the policy provides an opportunity for deliberation and explanation, thus enabling more probing judicial scrutiny of agency reasoning without triggering concerns about diverting agency resources or forcing an articulation of undisclosed internal priorities. (199)

Nevertheless, for the same reasons that review of single-shot nonenforcement decisions is generally unmanageable, any substantive review of a policy that merely sets resource-allocation priorities should be highly deferential. (200) If the policy is expressly predicated on legal interpretation, courts should assess the interpretation's validity, as indeed they have done in some decisions. (201) Legal error in single-shot decisions may be tolerable given the low costs to statutory compliance and high costs to formalizing such decisionmaking. (202) But these costs and benefits reverse when an agency has formalized a mistaken interpretation in an otherwise reviewable general policy; and no problem of judicial unmanageability preludes assessing an express legal interpretation (subject to any applicable degree of deference). (203) Relatedly, the policy may properly be subject to judicial review on procedural grounds if the agency should have used notice-and-comment procedures. Under the APA, as currently interpreted, such procedures are required for "legislative rules," that is, rules that create "legally binding obligations or prohibitions," (204) but not "general statements of policy," including enforcement policies. (205) While case law drawing this distinction is notoriously confused and imprecise, courts have generally sought to detect when agencies have made an effectively binding determination of law without using the more participatory and deliberative procedures the APA requires for such acts of lawmaking. (206)

Yet if a policy surmounts these hurdles--if it is procedurally valid, does not involve explicit interpretation, and comports with any explicit statutory directives--courts should rarely look past a facially reasonable articulation of how the policy will advance the agency's statutory mission given resource limitations and practical constraints. Requiring some articulation of the policy's consistency with overall statutory or regulatory objectives may impose a useful discipline and help ensure public accountability for the agency's choices. (207) But more probing scrutiny could quickly involve the court in unmanageable judgments of relative importance, just as much as reviewing individual nonenforcement decisions would. After all, the policy only does overtly and formally what the agency must in any event do privately and informally. And while public articulation of the agency's priorities may carry costs to statutory compliance, it may also carry countervailing benefits. For one thing, it may facilitate managerial control of low-level enforcement decisions within the agency. (208) In addition, insofar as it alerts regulatory beneficiaries to agency practice and provides a focus for opposition, the policy may even facilitate pressure on the agency to redirect its efforts. (209) Weighing these benefits and costs is likely itself a judicially unmanageable inquiry and thus a matter properly "committed to agency discretion by law" under Heckler's interpretation.

Accordingly, to be concrete, were the current marijuana nonenforcement policy otherwise reviewable, (210) courts would have no manageable standard against which to assess the government's choice of priorities. The policy is expressly framed in terms of resource allocation, it emphasizes the policy's value in concentrating resources on crimes judged to be more significant (and more in accordance with traditional federal enforcement priorities), and it avoids any definite promise of future nonenforcement; it simply states the government's current judgment that marijuana offenses are not presently the most important to pursue. (211) Although I have elsewhere given it an uneasy defense on the merits, (212) the policy's unusually public character and dramatic real-world effects on compliance may raise concerns about its legitimacy as a matter of faithful execution. (213) The key point here is that such concerns are not judicially manageable; they should be left to political accountability and conscience. By the same token, current immigration enforcement priorities (applicable quite apart from the DACA and DAPA programs) merely focus enforcement efforts for the time being on cases the executive branch judges to be most important. (214) As OLC explained, the priorities accord with the limited general guidance Congress has provided with respect to enforcement, (215) plausibly identify the most important cases for emphasis given severely limited resources, and once again avoid any definite assurance of nonenforcement to any particular immigrants outside the priority categories. (216) While some again might question whether the priorities are correct, or whether they reflect the best effort at enforcement the government could undertake, these questions are not judicially manageable by conventional criteria.

In more technical areas--determining what levels of food impurity should trigger enforcement, for example (217)--judicial review to ensure reasoned consideration of relevant scientific information and stakeholder interests may be more manageable. (218) But in many cases that is so because the policy effectively interprets an indefinite background legal standard--and does so in a way that, absent direct review of the policy itself, will never come before courts for judicial review in the context of a concrete enforcement action. (219) Even in such contexts, insofar as the agency's policy ultimately reduces to a judgment that conduct is unlawful but nonetheless low priority, courts should review that determination of relative importance with great deference to the agency's more politically accountable judgments. (220) In the related, but arguably more consequential, context of agency denials of rulemaking petitions, recent decisions have given wide deference to stated justifications rooted plausibly in resource constraints and overall statutory objectives, so long as Congress provided no specific deadline for the agency's action. (221) By analogy, much the same degree of deference should apply to general enforcement priorities. (222)

Some have argued, to the contrary, that courts should probe beyond the face of policies to ensure they were adopted in a good-faith effort to advance statutory objectives. (223) On this view, the executive branch faithfully executes statutes when it genuinely tries to effectuate them; in contrast, it violates its take-care obligation when it deliberately underenforces laws it dislikes for policy reasons. In principle, this view of faithful execution is correct: the Take Care Clause obligates the executive branch to enforce the law as it is and not as executive officials wish it to be. (224) Nevertheless, framing the judicial inquiry in overtly subjective terms would compound problems of judicial unmanageability rather than alleviate them.

In other contexts the Supreme Court has sought to base decisions on objective features of laws rather than political labels. (225) Likewise, in formulating the political question doctrine more generally, the Court has indicated that judicial abstention may be warranted based on "the impossibility of a court's undertaking independent resolution without expressing lack of the respect due coordinate branches of government." (226) Here, too, courts should indulge a strong presumption that executive officials have acted in good faith--as in fact the Court did in Heckler by presuming executive officials were focused on how agency resources are "best spent" and whether the agency is likely to prevail in enforcement proceedings. (227) Courts, moreover, should recognize that executive officials may have legitimate reasons to take different positions in different contexts. (228) They might take a narrow view of their authority when advocating legislative reform, for example, but reconsider that view after legislative initiatives have failed. Relying on such political statements by senior officials to show bad faith, as one court did in assessing current immigration programs, (229) is at the very least a breach of inter-branch etiquette that risks compromising courts' own political neutrality. If courts lack objective reasons for deeming enforcement policies legally insufficient, they should leave the matter to the political process.

Heckler itself did recognize one important outer limit on nonenforcement policies. Despite deeming nonenforcement unreviewable as a general matter, the Court reserved consideration of "a situation where it could justifiably be found that the agency has 'consciously and expressly adopted a general policy' that is so extreme as to amount to an abdication of its statutory responsibilities." (230) Heckler's abdication backstop is itself an important indication that enforcement discretion is not plenary. Agencies must enforce the laws they administer; they cannot sit on their hands simply because they find those laws objectionable. Yet lower courts have rarely found violations of the abdication standard, (231) and the difficulties applying it again relate to the general problem of nonenforcement's judicial unmanageability, rather than any notion that it exhausts a proper conception of executive responsibility.

The essential problem with abdication is that instead of eliminating the unmanageable line-drawing problem, the abdication standard simply pushes the line further down. How much abdication amounts to Heckler-prohibited abdication? If an agency has limited resources and multiple laws to enforce, it necessarily must prioritize enforcement of some laws over others. Yet this reality creates insuperable level-of-generality problems in assessing abdication. If the agency brings no enforcement actions under one statute or provision but nonetheless prosecutes other violations vigorously, has it abdicated its responsibility under the first statute? Or has it instead faithfully executed its statutory responsibilities as a whole? Perhaps over time the agency should aspire to give some effect to each and every provision it enforces, but in practice doing so will likely prove impossible in any context in which new violations are constantly arising. On the contrary, the agency may properly prioritize new violations it judges to be more serious for the same reasons it prioritized past cases that it judged to be more serious. (232) The Justice Department might well choose always to focus more resources on terrorism offenses than marijuana possession; immigration authorities might consistently concentrate more resources on removing immigrants who commit crimes than those who do not. (233)

In Heckler, the Court cited the D.C. Circuit's decision in Adams v. Richardson as an apparent example of abdication. (234) Yet Adams may then be the exception that proves the rule: in Adams the court set aside an agency's apparent practice of giving no force whatsoever over an extended period to civil rights laws prohibiting disbursement of federal funds to segregated schools. (235) Outside of such extreme facts--a demonstrably well-funded agency failing totally, over an extended period and at a high level of generality, to implement a policy whose importance has objective constitutional underpinnings (236)--Heckler's abdication principle will rarely provide a principled way out of the problem of judicial unmanageability with respect to nonenforcement. (237)

In sum, at least in enforcement contexts characterized by severe resource-allocation challenges and a built-in expectation of heavily discretionary enforcement, judicial review of priority-setting agency enforcement policies will typically present unmanageable legal questions, in the peculiar sense that term has acquired in the political question context. The problem is not (or at least not necessarily) that the executive branch holds a core Article II prerogative to decline implementation of statutory policies. On the contrary, the Take Care Clause imposes a core obligation of faithful execution, and judicial review normally seeks to ensure faithful implementation of statutory policies. Insofar as an agency is simply prioritizing some violations over others in its enforcement efforts, however, courts lack the institutional legitimacy and competence to second-guess agency choices, and proposals to probe executive good faith or prevent abdication fail to provide a meaningful way out of this conundrum. Courts, accordingly, should rarely look past a facially reasonable justification, framed in terms of resource allocation and the agency's overall statutory mission, for focusing criminal or civil enforcement efforts in one area rather than another, if that is all the policy effectively does. Defining when this form of nonenforcement goes too far--when it crosses the boundary from faithful execution to deliberate undercutting of statutory objectives--is an inevitably imprecise undertaking; it is often more a matter of mindset and degree than any bright-line formulation. For that very reason, it is also judicially unmanageable: absent more specific statutory direction, courts lack principled, objective guideposts for determining that an agency must focus on one set of violations rather than another.

Limiting judicial review in this manner carries considerable potential costs to congressional supremacy in lawmaking: as the marijuana example well illustrates, it potentially allows enforcement agencies to make choices of enormous practical significance based on vague incantations of resource limitations and presumed enforcement discretion. For this reason, I have argued elsewhere that executive officials generally should not presume authority to make broad categorical exclusions from enforcement based on policy disagreement with the underlying substantive law. (238) But whether or not that view of executive responsibility is persuasive, the key point here is that limitations on judicial review have an independent basis. Reviewing nonenforcement decisions and policies will often tax courts' institutional legitimacy and competence, and such concerns about judicial capacity may abundantly justify existing limits on judicial review of nonenforcement. Framing judicial review's limits in these terms, however, carries important normative implications for current debates, implications to which I now turn.

III. IMPLICATIONS

Beyond its descriptive value, reframing the problem of judicial review of executive nonenforcement in terms of judicial incapacity rather than executive prerogative carries a number of implications. Without attempting to fully explore all possibilities, the following discussion briefly addresses several important normative implications. First, framing the unreviewability of non-enforcement in terms of judicial incapacity highlights that the executive branch may hold obligations of faithful execution, as a matter of conscience and political accountability, that extend beyond any responsibility courts will enforce. Second, the framework supports refocusing Heckler's presumption of unreviewability so as to permit review of enforcement policies that formally or functionally alter legal obligations in ways that go beyond the sort of purely negative judgment that Heckler deems unmanageable. Third, the framework supports a more active judicial role in approving DPAs than courts have played to date. Finally, and most tentatively, the framework supports rethinking standing doctrine to track problems of judicial unmanageability and likely congressional intent rather than an amorphous conception of constitutionally adequate injury.

A. Judicial Power and Executive Duty

The most direct and important implication of framing law enforcement as a political question is to highlight the gap between judicial power and executive duty. As the Supreme Court has emphasized with respect to other political questions, the decision that some legal obligation is not judicially enforceable is "very different" from determining that no legal obligation has been breached. (239) Indeed, one key purpose of deeming the question political is to impose accountability more squarely on the branch that made the determination in the first instance. Here, too, to the extent executive law enforcement choices are political questions, either because of textual assignment or absence of judicially manageable standards (or both), the reasons owe as much or more to institutional limitations on courts as to any persuasive conception of executive authority.

Certain executive nonenforcement decisions, or even entire nonenforcement policies, may violate ideal understandings of faithful execution and yet nonetheless evade judicial correction. In particular, disingenuous nonenforcement--policies and practices designed to weaken or undermine statutory policies rather than simply to focus resources to achieve greater compliance overall--may in principle defy an appropriate conception of executive responsibility. Such underenforcement indeed typified many regulatory agencies' practices during the Reagan and Bush Administrations. Reagan's EPA, for example, slashed overall enforcement rates dramatically while formally abolishing the agency's Office of Enforcement and transferring its functions to the agency's legal office; civil rights and OSHA enforcement also declined dramatically, in ways political opponents in Congress criticized and resisted. (240) Similarly, the Bush Administration apparently continued invalidated environmental safe harbors as a matter of enforcement practice even after a federal court deemed them inconsistent with the statute. (241) Even the current administration's marijuana enforcement policies, while framed in heavily caveated and noncommittal terms that I have elsewhere characterized as consistent with an appropriate executive mindset, (242) might come to violate an appropriate fidelity to statutory policies. The administration has already extended these policies beyond core marijuana offenses of possession and distribution to related financial crimes. In practice, moreover, despite their caveated character, the policies may well be hardening into the sort of perceived ironclad assurance of nonenforcement that executive officials generally should not presume authority to make.

Although all these examples present forms of potentially illegitimate policy-based nonenforcement of federal laws, they are also all examples of the sort of executive foot-dragging that I have argued courts have great difficulty correcting. That is true in part because in some cases ultimate redress might require compelling in-court prosecution, a remedy I have argued violates the separation of powers. But it is also true because judicial second-guessing of executive actions would involve questions of relative importance and appropriate managerial focus that courts have generally deemed unmanageable. Even apart from problems of reviewability addressed here, standing limits and other procedural doctrines may limit courts' ability ever to hear a case challenging such executive choices. Yet even without judicial oversight, the executive branch retains an obligation, as a matter of "accountab[ility]" and "conscience," (243) to execute congressional enactments faithfully, however imprecise and contested the content of that obligation may be.

On some level, this understanding is no doubt intuitive to many executive branch officials. Conscientious executive officials approach law enforcement responsibilities with a sense of obligation to the law, tempered by appreciation for the very real practical discretion they exercise (and guided, of course, by directives from any more senior officials), (244) At the same time, this framing captures important features of public debates over enforcement. Although partisan animosity has made debates over Obama Administration policies particularly fevered, past debates under Republican administrations have also been inflected by assertions of legal obligation, in much the same way that debates over other political questions (such as war powers and foreign affairs) include legal dimensions notwithstanding courts' reluctance to consider the issues. (245)

More concretely, the framework supports independent elaboration of legal limits on enforcement discretion by the executive branch itself. OLC's important recent immigration opinion did just that. It expressly recognized the gap between executive obligation and judicial review with respect to enforcement, and indeed denied approval to one proposed program that transgressed boundaries it independently articulated. As the Office correctly observed, "Limits on enforcement discretion are both implicit in, and fundamental to, the Constitution's allocation of governmental powers between the two political branches," even if those limits are "not clearly defined" and "the exercise of enforcement discretion generally is not subject to judicial review." (246) Whether or not its bottom-line conclusions are persuasive (an issue I do not address here247), independent executive consideration of the issue is important in this context, as with respect to other political questions.

Courts can do their part, too. In particular, courts might reinforce the appropriate executive mindset by being clearer about the reasons for judicial passivity with respect to executive nonenforcement. In Heckler and other key cases, the Supreme Court has repeatedly invoked nonenforcement's judicial unmanageability--its "general unsuitability for judicial review" (248)--as a central basis for limited judicial intrusion on nonenforcement. At the same time, many have presumed that limited judicial review implies absolute executive discretion. But this equation is false. The central import of the political question doctrine is that judicial remedies do not always exhaust legal and constitutional obligations. As one scholar observes in another context, "In a world in which enforcing the Constitution is seen as overwhelmingly the responsibility of the courts, assignment of constitutional questions wholly outside of the judicial branch too easily becomes equated with denying that those questions have any real constitutional basis." (249) Here, too, a clear holding that enforcement choices are political questions, in the sense that they belong institutionally to the executive branch rather than the courts, could help encourage an appropriate sense of internal obligation within the executive branch. (250)

B. Refocusing Heckler

A second important implication relates to Heckler's presumption of unreviewability under the APA. If judicial unmanageability provides the most cogent explanation for viewing nonenforcement decisions as "committed to agency discretion by law," and if problems of judicial unmanageability further support highly deferential review of even more general enforcement priorities, then by the same token courts should interpret the APA to permit more intensive scrutiny when problems of judicial unmanageability are absent. In particular, insofar as review is otherwise available, Heckler should not prevent courts from policing in at least limited ways the most important substantive limit on enforcement discretion: that as a default matter, enforcement discretion is an authority to ignore but not authorize, to allocate effort but not to change effective governing law. (251) At least two types of policies may raise this concern in a judicially manageable fashion: those that purport to change legal obligations formally as an exercise of enforcement discretion, and those that do so functionally in ways that go beyond the practically inevitable priority-setting inherent in resource-constrained enforcement.

1. Formal Changes in Law

To begin with, Heckler has no relevance to policies and administrative actions that formally alter law rather than simply decline to enforce it. Policies that purport to change general legal obligations require a basis in delegated interpretive or rulemaking authority, not mere enforcement discretion. Accordingly, to fall within Heckler's presumption, a policy must be framed in terms of the problems of unmanageability that support Heckler s APA interpretation--they must establish priorities for current enforcement, not definite assurance that prohibited conduct will be considered lawful.

The Supreme Court recently drew this distinction forcefully in Utility Air Regulatory Group v. EPA (UARG). (252) The Court there invalidated, as inconsistent with unambiguous statutory text, an EPA rule regulating certain greenhouse gas emissions but adjusting upward (by a factor of roughly a thousand) statutory pollution thresholds for required permits. (253) The Court then explained that enforcement discretion failed to provide authority for this "Tailoring Rule." (254) "The Tailoring Rule," the Court explained, "is not just an announcement of EPA's refusal to enforce the statutory permitting requirements; it purports to alter those requirements and to establish with the force of law that otherwise-prohibited conduct will not violate the Act." (255) Indeed, such substantive effect was essential to the rule's operation, as the statute in question permits private as well as public enforcement of substantive requirements; private citizens could thus sue to enforce statutory thresholds if the agency did not. (256) Yet if the agency lacked interpretive authority to adopt the rule, as the Court held (whether correctly or not), (257) then the agency also lacked authority to achieve the same substantive result through nonenforcement. "An agency confronting resource constraints," the Court held, "may change its own conduct, but it cannot change the law." (258)

In UARG's peculiar statutory context, this holding reinforced the Court's conclusion that a broader regulatory program as a whole was inconsistent with applicable statutes. In other cases, however, this principle may support invalidating unduly permissive rules and policies that purport to excuse conduct prohibited by applicable substantive law. Doing so requires no unmanageable assessment of relative importance; it involves only straightforward legal interpretation (under applicable principles of deference). To be sure, even if its interpretation is invalid, the agency might nonetheless choose not to enforce in particular cases. But judicial intervention is nevertheless meaningful, as it restores the deterrent effect of the background law. Furthermore, without such invalidation, regulated parties might well have a due process right to rely on the agency's statement of law, notwithstanding its invalidity. (259) Judicial review of such rules and policies thus may powerfully enforce the basic principle that enforcement discretion is an authority to ignore but not authorize.

For much the same reason, as some courts have recognized, administrative decisions to grant waivers, licenses, and permits are not nonenforcement and therefore fall outside Hecklers presumption. (260) By definition, these actions affirmatively change legal obligations; they legalize conduct that would otherwise violate applicable statutes or regulations. (261) To be sure, whether to enforce legal prohibitions following the denial of a waiver or permit, or against parties who fail to apply for them in the first place, may present questions of enforcement discretion within Heckler's scope. (262) But waiver and permitting decisions themselves do not implicate the particular problems of resource-allocation and judicial unmanageability addressed above.

These principles, finally, may be relevant to some statutory schemes that, in context, seem designed to require affirmative approval for conduct rather than simply providing for after-the-fact enforcement. At the least, this possibility may account for an otherwise perplexing (and controversial) decision by the D.C. Circuit, Cook v. FDA. (263) Addressing facts oddly similar to Heckler's, the Cook court held that the FDA's announced policy of allowing importation of lethal-injection drugs to state officials administering capital punishment was reviewable despite Heckler and legally invalid. But while Heckler involved domestic production and distribution of the allegedly unapproved and unsafe drugs, Cook involved their importation from unregistered facilities overseas. Parsing the specific statutes governing drug importation, the Cook panel concluded that, notwithstanding Heckler, the FDA held a mandatory duty, first, to sample drugs imported from unregistered overseas facilities and, second, to "refuse[] admission" to any that "appear [ed]" to be an unapproved new drug or violate certain other statutory requirements. (264)

Assuming the court correctly construed these statutory requirements, Cook thus involved a choice to affirmatively allow otherwise forbidden prospective conduct, that is, importation of unapproved drugs from an unregistered facility. In contrast, Heckler, as the Cook court recognized, involved retrospective application of punitive and coercive remedies to alleged existing legal violations--the distribution and use of allegedly misbranded and unapproved new drugs. The statutory scheme in Cook, unlike in Heckler, thus effectively created a permitting regime--a regime under which the conduct in question was prohibited unless authorized, rather than tolerated unless punished. (265) The Cook court expressly recognized that the FDA could continue to "exercise enforcement discretion to allow the domestic distribution of a misbranded or unapproved new drug, as the Supreme Court recognized in [Heckler]." (266) Such a policy simply invites those using and distributing the drug to take their chances that the agency will not in the future shift priorities and prosecute them. But the FDA could not issue a blanket policy statement, as it had done in Cook, exempting the imports from review and approval and thus allowing the drugs' automatic importation. (267) By removing the default barrier to importation that Congress imposed, such a policy changes prospective legal obligations in a manner that a retrospective enforcement policy of the sort the Supreme Court considered in Heckler does not.

So understood, Cook, like UARG, illustrates the key outer boundary to Heckler, the boundary between retrospective priority-setting, which courts cannot manageably assess, and affirmative legal permission, which they can.

2. Functional Changes in Law

More difficult cases arise along the margins between nonenforcement and affirmative permission--actions that may functionally change law, even if they do not do so formally. As we have seen, any announced nonenforcement policy has this effect to some degree; by lowering the perceived risk of enforcement, such policies may free regulated parties to engage in prohibited conduct. The marijuana policies again powerfully demonstrate this effect. As some hapless defendants have discovered, the policies do not provide any binding assurance of nonenforcement. (268) Nor do they prevent other incidental legal burdens, potentially including civil liability, that track underlying criminal prohibitions. (269) Even so, these policies have dramatically altered private behavior, in a manner that even an undisclosed policy producing the same pattern of enforcement results likely would not have done.

Courts, I have argued, generally lack manageable standards for assessing the validity of such policies, despite their real-world effects, but that is true only insofar as such policies simply exercise overtly and formally a form of priority-setting that would be practically inevitable internally and informally in any event. As policies climb the ladder away from this inevitable priority-setting towards more affirmative assurances of nonenforcement, this calculus may change: courts may sometimes manageably assess whether adequate authority exists for the executive policy. That is true, to a limited degree, with respect to at least two types of policies.

First, even if they do not purport formally to change legal requirements, nonenforcement policies that are overly definitive--policies framed in terms of categorical assurances rather than precatory priorities--raise particular concerns about functional change in legal obligations. I have argued elsewhere that default separation of powers principles support a general presumption against categorical (as opposed to case-by-case) nonenforcement and that this presumption remains a useful heuristic in assessing faithful execution even when full enforcement is impossible. (270) UARG inadvertently illustrates this point. The Court there held that the Tailoring Rule could not be justified as enforcement discretion because citizen-suit provisions in the statute effectively ousted the agency's enforcement discretion, permitting it to tailor substantive prohibitions only by interpreting them away, rather than simply not enforcing them. (271) But suppose the statute provided only for official enforcement. In that case, a tailoring rule regarding agency enforcement would effectively replace background substantive requirements as the law regulated parties would need to follow. Yet if resource constraints can justify only a change in an agency's "own conduct," but not "the law," how could such a policy constitute faithful execution of the statute? (272)

To avoid this problem, a degree of precatory indeterminacy in enforcement policies is often an important expression of fidelity to background substantive law. Pasting a sign below a 55-mile-per-hour speed limit that says "enforced only against drivers exceeding 65 miles per hour" changes the effective law (from the perspective of regulated parties at least) in a more significant way than either an undisclosed internal police guideline or a less definitive policy. In principle, then, framing enforcement policies is not an entirely ungoverned choice between rules and standards, as some have argued. (273) In crafting substantive statutes or rules or common-law doctrines, the choice between rules and standards involves a straightforward tradeoff between the imprecision and unpredictability of standards, on the one hand, and the inevitable over- and under-inclusiveness of rules, on the other. (274) In contrast, a nonenforcement policy by definition does less than the background law requires; the only question is how much less is permissible and why.

This intuition, indeed, underlies case law mentioned earlier that seeks to identify legislative rules requiring notice-and-comment procedures based in part on whether the rule appears practically binding. (275) Though heavily criticized as an interpretation of the notice-and-comment exceptions, (276) this case law does at least indirectly enforce the requirement of indeterminacy in nonenforcement policies: agencies avoid framing such policies in definitive terms, because doing so increases the likelihood that courts will require costly notice-and-comment procedures. (277) In at least some contexts, however, the issue may be substantive as well as procedural. If conduct falls within a statutory prohibition that the agency cannot plausibly interpret not to apply, then notice-and-comment procedures may well be beneficial with respect to the agency's formulation of enforcement policy, but they cannot provide authority that would otherwise be lacking to implement an overly definitive assurance of nonenforcement. (278)

Courts accordingly should set aside otherwise reviewable nonenforcement policies that are framed in entirely categorical terms and cannot be justified as interpretation. To give one example highlighted in a recent essay, were the IRS to announce, as it has in one policy, that it "will not assert" that any taxpayer has underreported income by failing to include certain received benefits, and that "[a]ny future guidance on the taxability of these benefits will be applied prospectively," (279) then courts should set aside the policy as substantively invalid unless it can be justified as a valid interpretation of underlying tax laws. (280) Doing so might in the end affect only the framing of such policies; the agency might respond with a policy framed in more precatory terms, describing enforcement as a low priority rather than a definite guarantee. But framing matters in nonenforcement policies: a risk-averse taxpayer might well choose to comply in the latter case but not the former. What is more, the more precatory formulation might help encourage an appropriate mindset among agency personnel about the limits of their authority to rewrite effective requirements that Congress has imposed. (281) In some contexts a more precatory policy might also create a broader opening for regulatory beneficiaries to petition for enforcement in unusual cases.

All that said, courts should enforce this principle in only the clearest cases. Framing nonenforcement priorities in relatively categorical terms may sometimes carry important benefits. In particular, such policies may enable greater consistency of implementation and hierarchical control throughout a far-flung agency. (282) Furthermore, insofar as policies fall along a spectrum of definitiveness, determining where to draw the line--how categorical is too categorical?--may itself be unmanageable. Indeed, some scholars have faulted the "practical effect" analysis for legislative rules on precisely this basis. (283) In assessing the agency's ultimate authority, moreover, courts should be loath to look past the face of the policy to its actual implementation, as some courts have done in assessing the binding effect of putatively non-legislative rules. (284) Relatively categorical implementation of even indefinitely framed priorities may often strike the best balance possible between legitimate competing objectives--maintaining internal discipline and signaling particular regulatory concerns, on the one hand, and avoiding excusing unlawful conduct outside the agency's priorities on the other. (285) Much as with the choice whether to formulate a policy in the first place, the balance of these tradeoffs is likely not an inquiry that courts can objectively manage.

A second type of policy, however, may take the problem of categorical assurance a step further by providing assurances that are not only categorical but also prospective--that is, expressly applicable to future as well as past or current conduct. Although immigration is unique in many ways (some addressed below (286)) and this characterization is itself disputed in current litigation, DACA and DAPA in effect have this character. These programs invite large categories of undocumented immigrants to apply for deferred action, a formally revocable (but likely practically effective) promise of non-removal for a specified period (here three years). (287) Although the programs involve a degree of case-by-case consideration, they appear designed to make deferral the rule rather than the exception for the covered groups. (288) Moreover, under a preexisting regulatory interpretation of the statute, granting deferred action renders immigrants eligible for work authorization (among other benefits), which would otherwise be prohibited. (289)

As even some proponents recognize, the structure of these policies--affirmative assurance of nonenforcement to a broad subset of parties engaged in what is arguably a continuing violation of law (290)--raises concerns as a model of enforcement discretion precisely because resource constraints, and resulting underenforcement, are so pervasive in modern criminal justice and administration. (291) DACA's and DAPA's beneficiaries are enormously sympathetic and should be low priorities for removal under any sensible immigration enforcement policy. (292) Furthermore, were the Court to accept the government's characterization of the programs as nothing more than conventional priority-setting, all the problems of judicial manageability addressed earlier would justify a limited judicial role. Yet the peculiarly definitive form of nonenforcement involved in these policies might also distinguish them from such more conventional policies. At the least, if resource constraints and organic agency enforcement discretion were sufficient by themselves to justify exercising nonenforcement authority in the form asserted in these cases, a future administration with different policy predilections might likewise excuse ongoing violations in any number of politically contested areas of law--pollution limits or tax underpayments or federal firearms prohibitions, for example. (293)

Reviewing courts should therefore seek immigration-specific authority for DACA and DAPA. Doing so might properly entail reliance on somewhat unconventional considerations such as past executive practice and congressional ratification (the approach OLC employed), (294) and executive officials should perhaps receive deference with respect to judgments about the ultimate scale of the programs and their utility in concentrating resources more effectively on higher-priority objectives. Nevertheless, as lower courts have recognized, there is ultimately nothing unmanageable about reviewing general enforcement policies for "legal sufficiency." (295) Accordingly, to the extent the particular form of categorical and prospective relief provided by these programs requires affirmative statutory authority beyond an agency's default organic enforcement discretion (and to the extent the policies are otherwise reviewable and pertinent issues are properly presented in the litigation (296)), Heckler should present no obstacle to assessing, however deferentially, whether such authority exists. (297)

Prior precedent, concededly, has not always recognized this distinction. But by the same token previous cases highlight the issue's ramifications well beyond the immigration context. Consider, for example, the D.C. Circuit's recent decision in Ass'n of Irritated Residents v. EPA (AIR). (298) In that case, a divided panel applied Heckler to uphold a Bush Administration environmental program that invited a broad class of polluters to enter identical consent decrees precluding enforcement, even for future violations, for two years or more. (299) The policy in question applied to "animal feeding operations," a type of farm operation that appeared likely to produce pollution exceeding statutory limits under the Clean Air Act. (300) The consent decrees nonetheless barred future enforcement suits for both past and ongoing violations in exchange for relatively slight civil penalties and participation in an emissions-monitoring study. (301) As one judge complained in dissent, this program "replace[d] the enforcement scheme in three congressional statutes with an unauthorized system of nominal taxation of regulated entities." (302) It thus altered prospective legal obligations on a general basis. To be sure, in any single enforcement action, courts may well have had no manageable criteria to second-guess an agency's choice to resolve the suit by consent decree. (303) But here the sum was greater than its parts: by categorically offering general terms to all covered farm operations, the agency effectively altered the legal regime for an entire industry, and indeed did so in a way that legally tied the agency's hands so as to prevent shifting to more robust enforcement while the decrees remained in force. The court should have evaluated on the merits whether EPA's statutes provided sufficient authority for the program and whether the program was indeed reasonably calculated to achieve long-term statutory compliance, as the agency claimed. (304) It should not have simply waved the suit away as a challenge to agency enforcement discretion.

OLC, in contrast, recognized the need for more specific indications of congressional approval in its opinion upholding DAPA. (305) DAGA and DAPA are distinguishable from the program in AIR insofar as deferred action, unlike a consent decree, is not legally binding; the agency in principle may revoke it at any time. If the programs operate as intended, however, they will practically bind future enforcement; that is one important reason for providing deferred action rather than relying only on internal priorities. (306) Moreover, insofar as providing deferred action enables work authorization (among other benefits), the policy effects a prospective change in future legal liabilities and obligations. (307) Much as in AIR, the sum here is greater than its parts: while courts might have no objective basis to question deferral with respect to any particular removable immigrant, the scale and generalized character of these programs, coupled with the prospective nature of the promised nonenforcement and the change in legal relations effected by work authorization, creates particular concern about the programs' consistency with underlying substantive laws being enforced. Courts may address that concern without falling afoul of the problems of unmanageability underlying Heckler. Invalidating the programs, after all, would not necessarily result in enforcement in any particular case; nor indeed would it preclude adoption of enforcement priorities that limit the effective risk of removal for immigrants within the affected categories. (308)

Immigration law holds many peculiarities, and several immigration-specific theories of authority have by now been advanced. OLC itself found sufficient legislative support for DAPA (but not a further proposed program) in past congressional ratification of analogous executive actions. (309) Others have faulted OLC's analysis and advanced a broader theory of "de facto delegation" to justify the administration's action. (310) Some view the preexisting regulatory interpretation of the statute as dispositive, (311) or emphasize the inevitably prospective character of immigration nonenforcement (in which failing to remove someone effectively means allowing them to stay). (312) Whatever the correct view of the merits (a point I do not address here (313)), Heckler does not prevent courts from addressing them. At the very least, Heckler should not prevent evaluation of challengers' claims that the programs in question exceed the form of conventional, retrospective priority-setting that Heckler properly exempts from APA review. Here, as with respect to some overly definitive nonenforcement policies, courts can manageably police the outer bounds of organic executive nonenforcement authority. (314) Doing so is important because without such immigration-specific analysis, the example set by these programs could readily migrate into many other areas of law, such as the environmental enforcement regime considered in AIR, where concerns about regulatory capture and shortchanging of regulatory beneficiaries would carry greater force.

C. Reviewing Deferred Prosecution Agreements

A third implication of the framework is that Congress may enable a broader judicial role with respect to nonenforcement if it so chooses. Insofar as problems of judicial manageability result ultimately from the indeterminacy of statutory priorities rather than any more fundamental limit on judicial power, nothing in the Constitution precludes Congress from authorizing broader judicial review, so long as Congress stops short of requiring judicially compelled prosecution. Congress, moreover, might impose limits on executive enforcement discretion either by doing so directly (a possibility Heckler expressly held open (315)) or by authorizing judicial elaboration of faithful-execution standards. In at least one important context--DPAs--Congress has effectively done just that, yet many courts have persisted in rubber-stamping the parties' proposals, presumably out of a misplaced fear of interfering with prosecutorial discretion.

As described earlier, DPAs enable the government to file criminal charges against an alleged wrongdoer and yet defer actual prosecution without falling afoul of Speedy Trial Act deadlines in exchange for the defendant's acceptance of specified conditions. (316) DPAs thus differ from plea agreements and judicially approved settlements in that they do not involve a calculated compromise of the two sides' risks and liabilities. Instead, these agreements leverage the government's discretion not to prosecute so as to induce prospective changes in the targeted firm's or individual's behavior. (317) Presumably for this reason, courts have shown even greater deference to DPAs than is typical of settlements and plea deals (which are themselves reviewed with great deference). (318) Yet such absolute judicial passivity is misplaced. By law DPAs are authorized only for a specified purpose--to enable "the defendant to demonstrate his good conduct." (319) No separation of powers difficulty, nor any problem of judicial unmanageability, prevents courts from giving content to this statutory standard.

What practical meaning might this standard carry? The Speedy Trial Act's legislative history makes plain that Congress contemplated use of this device to divert minor, non-violent offenders from criminal punishment, so as to avoid the stigma of conviction and facilitate their rehabilitation. (320) Particularly in light of that background, "good conduct" in this context most naturally means rehabilitation, that is, a demonstrated commitment to avoid further crimes of the sort alleged in the underlying charges. A Senate Judiciary Committee report on the Act indicated as much. It referred approvingly to state and federal experiments with "pretrial diversion or intervention programs in which prosecution of a certain category of defendants is held in abeyance on the condition that the defendant participate in a social rehabilitation program." (321) Evidently presuming that the government would otherwise prosecute the defendants in question, the Committee observed: "Of course, in the absence of a provision allowing the tolling of the speedy trial time limits, prosecutors would never agree to such diversion programs." (322) Nevertheless, the Committee explained the requirement of judicial approval--deliberately added to the bill as a change from earlier versions--as a necessary constraint on potential abuse. By "requir[ing] that exclusion [of time] only be allowed where deferral of prosecution is conducted 'with approval of the court,'" the Committee explained, the statute "assures that the court will be involved in the decision to divert and that the procedure will not be used by prosecutors and defense counsel to avoid the speedy trial time limits." (323)

While it may not be entirely clear what rehabilitation means in the corporate context, this statutory structure plainly does not leave defining "good conduct" up to the executive branch alone. Though now restricted by internal Justice Department guidance, some past DPAs have included terms bearing no evident relation to assuring future compliance with the statutes being enforced. (324) In the most notorious cases, the agreements have required endowing a law school professorship as a remedy for suspected price-fixing, promising to retain a specified number of jobs in the state to remedy accounting fraud charges, and installing slot machines (to ensure state gambling revenue) as a remedy for alleged fraud and corruption. (325) On the other hand, some commentators have faulted many DPAs for doing too little to assure genuine reform within the targeted firm. (326) As one thorough recent study reports, "many corporate prosecution agreements do not impose serious structural reforms." (327) A more active judicial role could prevent abuses in both directions--both those that leverage threats of prosecution to impose unrelated conditions, and those that grant deferrals with insufficient assurance of genuine rehabilitation. (328)

The framework developed here makes clear why such judicial elaboration of appropriate DPA standards violates no constitutional prerogative of the executive branch. Judicial oversight of executive nonenforcement is normally unmanageable, in the peculiar sense the term has developed in political question cases, because Congress has foisted enforcement choices onto the executive branch that courts lack any objective yardstick to assess. But by the same token the Constitution poses no obstacle to common-law judicial standard-setting in contexts where Congress provides for it. In other words, if courts normally abstain from policing executive enforcement choices because they lack legitimacy and institutional competence to do so, the rationale for such judicial passivity disappears when Congress legitimates a more robust judicial role. To be sure, any judicially developed standards might well give significant deference to executive judgments, particularly with respect to the strength of the government's case and the appropriate balance between forbearance and punishment with respect to fines and other punitive measures. But whatever else it intended when it passed the STA, Congress expressly provided for a judicial role in policing the novel practice of DPAs. Article II affords no reason for courts to refrain completely from exercising this power.

D. Rethinking Standing

Finally, and most tentatively, the framework developed here has implications for long-running debates over Article III standing to challenge government inaction. In its leading decisions on standing to challenge executive inaction, the Court has associated Article III limitations on cognizable injury with Article II authorities of the executive branch. In particular, the Court has suggested that complaints shared by the public as a whole are properly matters for resolution by politically accountable executive officials, not federal courts. (329) Yet standing limits at best insulate executive enforcement decisions from judicial oversight only indirectly. As Heather Elliott observes, "The question whether a particular plaintiff has standing is essentially unrelated to the question whether Congress violates the Constitution by enlisting the courts to fight its battles with the executive branch." (330)

At least in the nonenforcement context, viewing law enforcement as a political question responds more directly to concerns about improper judicial oversight of fundamentally executive functions. In Lujan, for example, the Court objected to plaintiffs "complaining of an agency's unlawful failure to impose a requirement or prohibition upon someone else." (331) Yet prohibiting compelled prosecution addresses this concern on the merits with respect to particular enforcement suits, while recognizing that most nonenforcement decisions are judicially unmanageable protects such decisions more generally from judicial second-guessing. Even under Lujan, after all, standing doctrine permits complaints about executive failure to enforce laws in particular cases, provided the complaining party can establish a concrete, redressable injury traceable to the government's inaction. The political question framework developed here thus addresses more directly when judicial interference is unwarranted. If the Court believes nonenforcement should be left to political (rather than judicial) accountability in a broader set of circumstances, either because of an executive nonenforcement prerogative or because the problem is judicially unmanageable, it should say so directly and spare litigants the need to debate fine points about the concreteness of their injuries. Recognizing that the central obstacle to meaningful judicial review is often a lack of manageable standards, rather than any more fundamental Article II limit, thus reinforces the longstanding critique that standing doctrine should not preclude legal challenges where Congress has specifically provided for them. (332)

That is not to say that the floodgates should necessarily be opened to litigation challenging executive nonenforcement. Recognizing law enforcement as a political question instead reinforces longstanding arguments for treating standing as an essentially statutory rather than constitutional inquiry. (333) Even today, standing has both statutory and constitutional components. The APA generally limits suits to persons "suffering legal wrong" or "adversely affected or aggrieved by agency action within the meaning of a relevant statute," capacious terms that invite judicial elaboration. (334) Accordingly, in addition to satisfying minimum Article III requirements, plaintiffs challenging government action (or inaction) must establish that their injury falls within the "zone of interests" that the statute aims to protect. (335) Although complete elaboration of this proposal would go beyond the scope of this Article, more robust development of statutory default rules might provide a more coherent set of standing principles, while at the same time preserving ultimate congressional authority to enable broader judicial oversight of executive enforcement decisions.

As the Court held, pre-Lujan, in Linda R.S., it could be that certain areas of law subject to heavily discretionary, exclusively public enforcement, such as federal criminal law, protect no one in particular but only the public at large, thus leaving no particular individual with standing to challenge nonenforcement. (336) But to the extent that is true, the fault should lie ultimately with Congress rather than the Constitution. As is already true with respect to zone-of-interests analysis, the focus of inquiry should be on whose interests Congress meant to protect, rather than on whether those interests satisfy some abstract notion of concreteness.

CONCLUSION

Although cases and commentary often describe nonenforcement as an executive prerogative, immune to judicial or congressional control, exercises of executive enforcement discretion are better understood to present a form of political question--an executive obligation subject to incomplete judicial enforcement. In the political question doctrine's terms, one narrow but important enforcement function, bringing particular civil or criminal enforcement suits in court, is "textually assigned" to the executive branch and thus beyond direct judicial control. Broader enforcement questions, including most administrative nonenforcement and more general nonenforcement practices and policies, frequently involve "judicially unmanageable" questions that courts should leave to political rather than legal accountability. This framework makes clear that judicial doctrines do not exhaust executive obligations with respect to law enforcement. But the framework also highlights contexts, such as review of nonenforcement policies with affirmative elements and judicial approval of DPAs, where courts can play a broader role without Article II difficulty. Finally, the framework supports longstanding arguments that standing should be reoriented towards identifying statutory beneficiaries rather than abstract conceptions of sufficiently concrete injury.

The political question doctrine itself is controversial. Some question the merits of insulating any important legal or constitutional questions from judicial resolution on the merits, (337) while others doubt that denying a judicial remedy is meaningfully different from conferring unfettered discretion. (338) The argument presented here sheds light on these debates as well. If the key criteria for political questions may usefully describe and structure judicial inquiries with respect to so familiar an executive function as nonenforcement, then the argument presented here may reinforce the value of distinguishing between executive obligation and judicial enforcement more generally. What is more, elements of the structure I have presented here--a remedial (rather than substantive) limit on judicial authority, and substantial congressional responsibility for the problem's judicial unmanageability--might be relevant to other political questions as well, particularly war powers. At the least, the framework underscores that within our system of coequal branches and separated powers courts cannot enforce every obligation; some should be left to public officials' accountability and conscience. But by the same token, in law enforcement, as in other areas, the political branches should recognize that the limits of judicial supervision are not necessarily the limits of the law.

(25) Id. [section] 706(2). The APA also requires the reviewing court to "compel agency action unlawfully withheld or unreasonably delayed." Id. [section] 706(1). The Supreme Court has interpreted this provision to apply "only where a plaintiff asserts that an agency failed to take a discrete agency action that it is required to take." Norton v. S. Utah Wilderness All., 542 U.S. 55, 65 (2004). Insofar as statutes rarely require enforcement specifically in any discrete case, challenging nonenforcement under this standard would be difficult. See PETA v. U.S. Dep't of Agric., 797 F.3d 1087, 1097-98 (D.C. Cir. 2015) (rejecting challenge under section 706(1) to "decade-long" nonenforcement of statute with respect to class of cases). In any event, the exception to review for matters "committed to agency discretion by law" applies equally to sections 706(1) and (2) and thus, under Heckler, bars review of nonenforcement decisions.

(31) As the Supreme Court recently summarized:
   Review under the arbitrary and capricious standard is deferential;
   we will not vacate an agency's decision unless it "has relied on
   factors which Congress had not intended it to consider, entirely
   failed to consider an important aspect of the problem, offered an
   explanation for its decision that runs counter to the evidence
   before the agency, or is so implausible that it could not be

(32) For a sampling of literature addressing these points, see for example Louis L. Jaffe, Judicial Control of Administrative Action 320 (1965) "The availability of judicial review is the necessary condition, psychologically if not logically, of a system of administrative power which purports to be legitimate, or legally valid."), Nicholas Bagley, The Puzzling Presumption of Reviewability, 127 Harv.

Metzger, Ordinary Administrative Law as Constitutional Common Law, 110 Colum. L.

(35) Id. at 832. For critique of this rationale, see id. at 851 (Marshall, J., dissenting) ("[O]ne of the very purposes fueling the birth of administrative agencies was the reality that governmental refusal to act could have just as devastating an effect upon life, liberty, and the pursuit of happiness as coercive governmental action."), and Sunstein, supra note 29, at 674-75 ("[U]nlawful governmental failure to act can be as harmful as unlawful action and is equally subject to judicial review under APA standards.").

(36) Heckler, 470 U.S. at 832 (quoting U.S. Const, art. II, [section] 3).

(37) See, e.g., Metzger, supra note 32, at 492 ("[T]his basic requirement of reasoned explanation is central to alleviating core separation-of-powers concerns associated with the administrative state.").

(38) Two other key unreviewability cases may reflect a similar impulse to shield traditional executive functions from intrusive judicial oversight. In Webster v. Doe, 486 U.S. 592 (1988), the Court interpreted the governing statute to permit unreviewable, discretionary terminations of Central Intelligence Agency personnel in part because courts would have "no basis" for assessing the termination "[s]hort of cross-examination of the Director concerning his views of the Nation's security and whether the discharged employee was inimical to those interests." Id. at 600; see also id. at 608-09 (Scalia, J., dissenting) (interpreting the APA to incorporate a common law of unreviewability based in part on "a traditional respect for the functions of the other branches"). Similarly, in Lincoln v. Vigil, 508 U.S. 182, 193 (1993), the Court held allocation of funds from lump-sum appropriations to be unreviewable based on an asserted traditional understanding that "the very point of a lump-sum appropriation is to give an agency the capacity to adapt to changing circumstances and meet its statutory responsibilities in what it sees as the most effective or desirable way." Id. at 192. Some have also described Heckler, along with the decision in Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837 (1984), from the preceding year, as facilitating a more presidential model of administration by carving out broader areas of agency autonomy from judicial scrutiny. See, e.g., Bressman, supra note 15, at 1678 (associating Heckler with promoting presidential control of "complex and essentially political determinations" regarding enforcement priorities); Thomas, supra note 16, at 143 ("[A]s with the Court's Chevron decision a year earlier, Chaney at least implicitly recognizes that the decisions an agency makes are inevitably political....").

(39) See, e.g., Town of Castle Rock v. Gonzales, 545 U.S. 748, 761, 765 (2005) (rejecting claimed Fourteenth Amendment right to enforcement of state-law restraining order because of the "deep-rooted nature of law-enforcement discretion" and because of doubts that "state law gave respondent an entitlement to enforcement of the mandate").

(40) The Heckler Court reserved the question whether nonenforcement on racial or other constitutional grounds would be unreviewable. 470 U.S. at 838. The Court has since held that even when an employment termination decision was "committed to agency discretion by law" under the APA because the statute failed to permit "application of any meaningful judicial standard of review," the Court could nonetheless consider "colorable constitutional claim [s]" arising out of the termination. Webster, 486 U.S. at 600, 603.

(41) See, e.g., Reno v. Am.-Arab Anti-Discrimination Comm., 525 U.S. 471, 489 (1999) (rejecting selective-prosecution defense to deportation proceedings and noting that even in criminal prosecutions "we have emphasized that the standard for proving [selective-prosecution defenses] is particularly demanding, requiring a criminal defendant to introduce 'clear evidence' displacing the presumption that a prosecutor has acted lawfully" (quoting United States v. Armstrong, 517 U.S. 456, 463-65 (1996))).

(50) 468 U.S. 737, 739-40 (1984).

(51) 504 U.S. 555, 571-72 (1992).

(52) Allen, 468 U.S. at 761 (holding that the Constitution's assignment "to the Executive Branch, and not to the Judicial Branch, the duty to 'take Care that the Laws be faithfully executed'" supports denying "standing in a case brought, not to enforce specific legal obligations whose violation works a direct harm, but to seek a restructuring of the apparatus established by the Executive Branch to fulfill its legal duties"); see also Lujan, 504 U.S. at 577 ("To permit Congress to convert the undifferentiated public interest in executive officers' compliance with the law into an 'individual right' vindicable in the courts is to permit Congress to transfer from the President to the courts the Chief Executive's most important constitutional duty, to 'take Care that the Laws be faithfully executed.'").

In footnotes in two more recent cases, the Supreme Court asserted that standing limits derive entirely from Article III, not Article II. Vt. Agency of Nat. Res. v. United States ex rel. Stevens, 529 U.S. 765, 778 n.8 (2000); Steel Co. v. Citizens for a Better Env't, 523 U.S. 83, 102 n.4 (1998). Nevertheless, the Court has adhered firmly to the notion that plaintiffs lack standing to challenge legal nonenforcement unless the government's inaction causes them some specific personal injury that differentiates them from the public at large. See, e.g., Hollingsworth v. Perry, 133 S. Ct. 2652, 2656, 2668 (2013). What is more, in scholarly writing both Justice Scalia (Lujan's author) and Chief Justice Roberts (Hollingsworth's author) have forcefully advocated an Article II basis for limits on Article III standing. See John G. Roberts, Jr., Article III Limits on Statutory Standing, 42 Duke L.J. 1219, 1230 (1993) ("The Article III standing requirement that the judiciary act only at the behest of a plaintiff suffering injury in fact ... ensures that the court is carrying out its function of deciding a case or controversy, rather than fulfilling the executive's responsibility of taking care that the laws be faithfully executed."); Antonin Scalia, The Doctrine of Standing as an Essential Element of the Separation of Powers, 17 Suffolk U. L. Rev. 881, 896 (1983) ("Where the courts, in the supposed interest of all the people, do enforce upon the executive branch adherence to legislative policies that the political process itself would not enforce, they are likely (despite the best of intentions) to be enforcing the political prejudices of their own class.").

(53) Two other APA doctrines, finality and ripeness, may also obstruct judicial review of nonenforcement. See generally Mark Seidenfeld, Substituting Substantive for Procedural Review of Guidance Documents, 90 Tex. L. Rev. 331, 375-85 (2011) (describing doctrines and critically analyzing their application to guidance documents). Because these doctrines apply generally and have not specifically targeted nonenforcement, I do not focus directly on them here. These doctrines at any rate have not uniformly prevented consideration of nonenforcement where Heckler has been held not to apply. For a proposal to "massage" them to enable broader judicial review of guidance documents in general, see id.

(54) Compare, e.g., Ass'n of Irritated Residents v. EPA, 494 F.3d 1027, 1030 (D.C. Cir. 2007) (deeming general policy of entering identical consent decrees with certain polluters unreviewable), and Sierra Club v. Jackson, 648 F.3d 848, 856 (D.C. Cir. 2011) (deeming unreviewable agency's failure to prevent construction of allegedly unlawful pollution-emitting facilities), with Crowley Caribbean Transp., Inc. v. Pena, 37 F.3d 671, 675-76 (D.C. Cir. 1994) (deeming general enforcement policies reviewable), and Cook v. FDA, 733 F.3d 1, 7 (D.C. Cir. 2013) (reviewing refusal to prevent importation of unlawful medications).

(107) Id. In a new article tracing the historical origins of the political question doctrine, Tara Grove suggests that Mississippi v. Johnson was a political question case only insofar as it involved a state's assertion of "sovereign 'political rights' in court," a matter she asserts courts would address today as a matter of standing doctrine. Tara Leigh Grove, The Lost History of the Political Question Doctrine, 90 N.Y.U. L. Rev. 1908, 1916 n.30 (2015). Though Grove's argument is compelling in other respects, this account of Johnson overlooks the Court's description of faithful execution as a "purely executive and political" responsibility. Mississippi, 71 U.S. (4 Wall.) at 499; cf. Harrison, supra note 94, at 1375 ("[T]he fear that drives judicial reticence in political question cases is about second-guessing highly sensitive and discretionary decisions, even when those decisions are about or substantially constrained by legal principles.").

(118) The Supreme Court has recognized a related principle of judicial neutrality as a requirement of due process. In In re Murchison, 349 U.S. 133, 134, 139 (1955), the Court held that a judge who approved criminal charges as a "one-man grand jury" could not preside over the resulting trial. Id. at 139 ("We hold that it was a violation of due process for the 'judge-grand jury' to try these petitioners."). The Court explained: "Having been a part of [the single-judge grand-jury] process a judge cannot be, in the very nature of things, wholly disinterested in the conviction or acquittal of those accused. While he would not likely have all the zeal of a prosecutor, it can certainly not be said that he would have none of that zeal." Id. at 137; see also Caperton v. A.T.

(122) One article of impeachment accused Justice Chase of "authoritatively enjoin [ing]" the executive branch to prosecute. 14 Annals of Cong. 327 (1804). In discussing this charge at his trial in the Senate, the House managers advocating Chase's removal emphasized that such intrusion on independent executive judgment violated a constitutional obligation of neutrality--a duty, that is, to serve as an "impartial dispenser[] of justice between such as might resort [to the federal courts] for an adjustment of their differences." Id. Although the Senate ultimately acquitted Chase on all charges, even his attorneys appear not to have disputed the managers' conception of the proper judicial role. Id. at 543 (admitting "that he requested the District Attorney to assist [the grand jury] with his advice in making this inquiry"); see also id. at 549 (emphasizing Chase's acquiescence in the DA's and grand jury's determination that no crime occurred); id. at 142 (characterizing allegations in the article as "altogether erroneous"); id. at 144 (contending that it was Chase's "duty, when informed of an offence, which the grand jury had overlooked, to direct their attention towards it, and to request for them, and even to require, if necessary, the aid of the District Attorney in making their inquiries"). In any event, historians have pointed to Chase's trial as a watershed in chastening overzealous early judges and entrenching a more limited conception of the judicial role. See, e.g., R. Kent Newmyer, John Marshall and the Heroic Age of the Supreme Court 179 (2001); Stephen B. Presser, The Original Misunderstanding 156-58 (1991); Gordon S.

It extends to every offence known to the law, and may be exercised at any time after its commission, either before legal proceedings are taken, or during their pendency, or after conviction and judgment. This power of the President is not subject to legislative control."). But cf. Rachel E. Barkow, The Ascent of the Administrative State and the Demise of Mercy, 121 Harv. L. Rev. 1332, 1346 (2008) ("[T]he clemency power has faced increasing criticism for its inconsistency with the fundamental values of administrative law."). A majority of Justices in one case with no majority opinion suggested that state clemency decisions must comport with due process, but the extent of review they contemplated appeared limited to situations where "a state official flipped a coin to determine whether to grant clemency, or ... the State arbitrarily denied a prisoner any access to its clemency process." Ohio Adult Parole Auth. v. Woodard, 523 U.S. 272, 289 (1998) (O'Connor, J., concurring in part and concurring in the judgment); see also id. at 292 (Stevens, J., concurring in part and dissenting in part).

(142) Some have argued that nonenforcement is a lesser power necessarily implied by the greater power to issue pardons. See, e.g., Amar, supra note 125, at 429. A pardon or amnesty, however, has different requirements and effects from nonenforcement decisions. Whereas an award of clemency irrevocably excuses a completed criminal offense, nonenforcement turns a blind eye to legal violations. Moreover, nonenforcement may apply prospectively insofar as the offenses in question are incomplete or ongoing. Such prospective cancellation of legal requirements could arguably amount to a greater power than the power to pardon, insofar as it may induce non-compliance rather than simply excusing past violations. At any rate, the pardon power is limited to criminal rather than civil offenses, and the specific textual grant of pardon power may well imply that even as to criminal offenses clemency rather than nonenforcement is the proper means of exercising leniency. For further discussion of differences between clemency and nonenforcement, see Rachel E. Barkow, Clemency and Presidential Administration of Criminal Law, 90 N.Y.U. L. Rev. 802, 849 (2015).

(143) Powell v. McCormack, 395 U.S. 486, 517-18 (1969) (avoiding the question whether federal courts could "issue mandamus or injunctions compelling officers or employees of the House to perform specific official acts" because declaratory relief could resolve case).

(144) Cf. Saikrishna Prakash, The Essential Meaning of Executive Power, 2003 U. ILL. L. Rev. 701, 704 ("At bottom, the executive power is the power to execute the laws."). Although I do not further develop this proposal here, this remedial conception of political questions may have broader application. For example, courts might hold authority to adjudge the legality of a war by indirect means, but not to enjoin presidentially directed combat directly. On one controversial account, court judgments are always essentially precatory with respect to the executive branch because presidents hold independent authority to decline to execute them. Michael Stokes Paulsen, The Most Dangerous Branch: Executive Power to Say What the Law Is, 83 Geo. L.J. 217, 221 (1994) ("[T]he executive's power to interpret the law may, and should, be exercised independently of the interpretations of other branches, including those of the federal courts."). For a more limited view, see, for example, William Baude, The Judgment Power, 96 Geo. L.J. 1807, 1809 (2008) ("[T]he judicial power vested in Article III courts allows them to render binding judgments that must be enforced by the Executive Branch so long as those courts have jurisdiction over the case.").

(145) See, e.g., Gonzales v. Thomas, 547 U.S. 183, 186 (2006) ("[T]he proper course, except in rare circumstances, is to remand to the agency for additional investigation or explanation."); Florida Power & Light Co. v. Lorion, 470 U.S. 729, 744 (1985) ("If the record before the agency does not support the agency action, if the agency has not considered all relevant factors, or if the reviewing court simply cannot evaluate the challenged agency action on the basis of the record before it, the proper course, except in rare circumstances, is to remand to the agency for additional investigation or explanation."); Adams v. Richardson, 480 F.2d 1159, 1163 n.5 (D.C.

(154) As noted earlier, Heckler gave several additional rationales, beyond these "administrative" difficulties, for deeming nonenforcement unreviewable. In particular, it analogized administrative nonenforcement to a prosecutor's refusal to press criminal charges, indicated that nonenforcement is not "coercive" in character, and noted the absence of any clear "focus for review" when the agency takes no action. 470 U.S. at 832. Most commentators have not found these rationales compelling on their own. The analogy of criminal prosecution to administrative nonenforcement is strained, for reasons addressed earlier. See supra Section II.B. Emphasizing the non-coercive character of nonenforcement neglects the interests of regulatory beneficiaries who may be shortchanged by administrative inaction, and agencies would likely provide a record to enable "focus [ed]" review of nonenforcement decisions if the Court interpreted the APA to provide for review in the first place. For critique of these rationales in Heckler, see for example Biber, Judicial Review, supra note 16, at 486-88, and supra note 35.

(164) Agencies do present such evidence in some contexts, such as in suits challenging delays in rulemaking based on resource scarcity, but courts generally give great deference to agency claims of resource incapacity. See, e.g., WildEarth Guardians v. EPA, 751 F.3d 649, 656 (D.C.

Doe, 486 U.S. 592, 600 (1988) (describing Heckler as holding that "[s]ince the statute conferring power on the Food and Drug Administration to prohibit the unlawful misbranding or misuse of drugs provided no substantive standards on which a court could base its review, we found that enforcement actions were committed to the complete discretion of the FDA to decide when and how they should be pursued"). For general discussion of this issue, see Sunstein & Vermeule, supra note 157, at 178-81.

(169) Agencies do sometimes adopt regulations imposing procedural requirements and standards on enforcement efforts. For discussion of this case law, see infra note 272.

(170) For discussion of this point in the context of immigration law, see Cox & Rodriguez, supra note 63, at 151 ("In a world where nearly half of all noncitizens living in the United States are formally deportable, there can be no meaningful search for the congressionally preferred screening criteria.").

(171) 470 U.S. at 835-36.

(172) Congress does, of course, sometimes impose general constraints on enforcement priorities. See, e.g., Dep't of Homeland Security Appropriations Act of 2014, Pub. L. No. 113-76, div. F., tit. II, 128 Stat. 5, 251 (directing DHS to "prioritize the identification and removal of aliens convicted of a crime by the severity of that crime"); Cox & Rodriguez, supra note 63, at 151-53 (discussing other examples). My point is that in the absence of congressional direction the statute generally cannot be understood to provide judicially manageable standards for reviewing agency priorities. Even when Congress does provide such directions, courts would likely still lack manageable standards unless the agency openly defied the congressional directive or the legislation provided guidance specifically applicable to particular cases.

(173) For a recent application of this principle, see Speed Mining, Inc. v. Fed. Mine Safety & Health Review Comm'n, 528 F.3d 310, 318 (4th Cir. 2008) (declining to review enforcement decision for consistency with the "purposes and policies" of the statute because doing so would "render the principles of nonreviewability [established by Heckler] null and void"). See also Sec'y of Labor v. Twentymile Coal Co., 456 F.3d 151, 158 (D.C. Cir. 2006) (rejecting "purposes and policies" standard for review because "it invites the reviewing body to substitute its views of enforcement policy for those of the Secretary").

(174) See Cox 8c Rodriguez, supra note 63, at 152-53 (elaborating this argument). Cox and Rodriguez's use of this argument to support DACA and DAPA is not necessarily persuasive, insofar as those programs require more affirmative legal authority than organic agency enforcement discretion. See infra text accompanying notes 291-97.

(186) The Supreme Court indeed stated in Massachusetts v. EPA, 549 U.S. 497, 527 (2007), that agency resource-allocation discretion is "at its height when the agency decides not to bring an enforcement action." The Court, however, did not specifically address general nonenforcement policies, but rather distinguished case-specific nonenforcement from failure to initiate rulemaking. Id. at 527-28.

(187) See, e.g., Bhagwat, supra note 15, at 158; Bressman, supra note 15, at 1690-91. This argument traces a lineage to Kenneth Culp Davis's argument in Discretionary Justice that administrative prosecutorial decisionmaking should be bound by rales to the maximum degree possible. Kenneth Culp Davis, Discretionary Justice 55 (1969). For an account placing Davis's argument within contemporary intellectual currents and the broader trajectory of Davis's work, see Reuel E. Schiller, Enlarging the Administrative Polity: Administrative Law and the Changing Definition of Pluralism, 1945-1970, 53 Vand. L. Rev. 1389, 1414 (2000).

(192) See Biber, Resource Allocation, supra note 16, at 35 (noting this concern); cf. Bressman, supra note 15, at 1693-04 (acknowledging "considerable costs, both in terms of administrative flexibility and administrative efficiency," in requiring probing arbitrariness review of nonenforcement decisions).

(193) See 5 U.S.C. [section] 552(b) (7) (2012) (exempting from required disclosure agency documents whose production "would disclose guidelines for law enforcement investigations or prosecutions if such disclosure could reasonably be expected to risk circumvention of the law"); Mayer Brown LLP v. IRS, 562 F.3d 1190, 1193 (D.C. Cir. 2009) (explaining this provision in terms of "the importance of deterrence").

(194) See infra text accompanying notes 208-09.

(195) See, e.g., Bressman, supra note 15, at 1690-93 (proposing to require agency "standard-setting" so that particular enforcement decisions could be judged against pre-established standards); Bhagwat, supra note 15, at 182-83 (similar).

(196) Proponents of this view often focus on contexts in which the agency has broad effective lawmaking authority and the regulatory context makes it likely that regulated parties (but perhaps not regulatory beneficiaries) will detect the agency's unstated enforcement patterns even if the agency articulates no public enforcement policy. See, e.g., Bhagwat, supra note 15, at 175-76 (suggesting that in heavily regulated industries enforcement patterns may become apparent to regulated parties even without any formal statement of policy). The proposals to regularize agency enforcement discretion may well carry greatest force in that context, but these concerns cannot necessarily be generalized to other contexts where substantive statutes are more specific or regulated parties less attuned to agency choices.

(197) Federal courts' approach to the procedural rule on criminal charge dismissals provides an instructive comparison to Heckler's interpretation of the APA. Federal Rule of Criminal Procedure 48 requires judicial approval for any dismissal of criminal charges. See Fed. R. Crim. P. 48(a) ("The government may, with leave of court, dismiss an indictment, information, or complaint. The government may not dismiss the prosecution during trial without the defendant's consent."). When the Supreme Court adopted this rule in 1944, it apparently aimed to conform federal procedure to state reforms requiring judicial approval of charge dismissals. See United States v. Cowan, 524 F.2d 504, 510-11 (5th Cir. 1975) (describing history of federal rule). Those state reforms, in turn, apparently aimed to limit perceived prosecutorial laxity by preventing discretionary charge dismissals. See Abraham S. Goldstein, The Passive Judiciary 14, 17-18 (1981).

If federal criminal law were more uniformly enforced, and prosecutorial discretion less central to federal criminal justice, reviewing the government's reasons for charge dismissals in this way might have helped ensure equity among defendants and more complete enforcement of applicable laws. But against the backdrop of extensive nonenforcement, including many crimes that are never charged at all, courts have no manageable standard against which to assess prosecutorial choices, and requiring reason-giving in the limited context of charge dismissals would do little to enforce equity among defendants. It too, moreover, could be counter-productive from the standpoint of deterrence if it forced the government to reveal undisclosed priorities. See United States v. Armstrong, 517 U.S. 456, 465 (1996) (limiting discovery to prove selective prosecution in part because of concerns about impairing "prosecutorial effectiveness by revealing the Government's enforcement policy" (internal quotation marks omitted)). Courts have thus effectively limited the rule to contexts in which prosecutors appear likely to proceed in any event, but in an abusive or harassing fashion. See, e.g., In re United States, 345 F.3d 450, 452-53 (7th Cir. 2003) (indicating that the rule's "purpose, at least the principal purpose, is to protect a defendant from the government's harassing him by repeatedly filing charges and then dismissing them before they are adjudicated"); In re Richards, 213 F.3d 773, 786-87 (3d Cir. 2000) (describing the "rarest of cases" in which "refusal to dismiss is appropriate"); United States v. Carrigan, 778 F.2d 1454, 1463 (10th Cir.1985) (identifying "prosecutorial harassment" or a threat to "the fair administration of criminal justice and the need to preserve the integrity of the courts" as the sole grounds for refusing dismissal).

EPA, 549 U.S. 497, 527 (2007) ("As we have repeated time and again, an agency has broad discretion to choose how best to marshal its limited resources and personnel to carry out its designated responsibilities."). The intensity of arbitrariness review is generally "context-dependent." Magill, supra note 20, at 1414; cf.

(220) Cf. Bhagwat, supra note 15, at 185 (arguing that reviewing courts should "modulate [their] level of scrutiny" depending on whether an enforcement policy depends on statutory interpretation or substantive policy, as opposed to resource-allocation and prioritization).

Cir. 2014) (upholding denial of rulemaking petition based on plausible, demonstrated resource-allocation justification for focusing on other regulatory objectives). The Supreme Court's earlier decision in Massachusetts v. EPA might be understood to permit more probing review of such decisions. For reasons to doubt that interpretation, see Sunstein & Vermeule, supra note 157, at 175.

(222) In fact, lower courts have generally given great deference to such priority-setting policies when they have reviewed them on the merits. See, e.g., Nat. Res. Def. Council, Inc. v. FDA, 760 F.3d 151, 170-71 (2d Cir. 2014) (observing that "[a]gencies have many responsibilities, and limited resources" and "[i]t is rare that agencies lack discretion to choose their own enforcement priorities"); Nat'l Roofing Contractors Ass'n v.

United States, 470 U.S. 598, 607-08 (1985))). It is true that in the related context of assessing whether an agency has "unreasonably delayed" taking action in violation of the APA, 5 U.S.C. [section] 706(1), some courts have considered "bad faith" as one factor among others in assessing the reasonableness of the agency's action. See, e.g., Indep. Mining Co. v. Babbitt, 105 F.3d 502, 510 (9th Cir. 1997); Telecomms. Research Sc Action Ctr. v. FCC ("TRAC"), 750 F.2d 70, 80 (D.C. Cir. 1984); Islam v. Heinauer, 32 F. Supp. 3d 1063, 1074 (N.D. Cal. 2014). But they generally have not engaged in an untethered subjective inquiry; they have instead looked for more concrete indications of bad faith, such as "singling someone out for bad treatment or asserting utter indifference to a congressional deadline."

U.S. Dep't of Hous. & Urban Dev., 170 F.3d 381, 384-85 (3d Cir. 1999) (rejecting abdication claim based on agency's alleged total failure to enforce particular regulation).

(233) Cass Sunstein and Adrian Vermeule have recently proposed extending Heckler s anti-abdication principle to agency delays addressing regulatory concerns. Under this proposal, which the authors themselves describe as "vague and not easily subject to judicial administration," an agency could not invoke resource allocation "repeatedly to keep a particular action at the back of the queue forever." Sunstein Sc Vermeule, supra note 157, at 162. Whatever the force of this proposal in the regulatory context, it has limited utility in the enforcement context in which the abdication concept originated. The Justice Department and other agencies do effectively keep particular types of violations at the back of the queue forever, precisely because other more pressing infractions are continually arising.

FAA, 743 F.3d 1168, 1173-74 (8th Cir. 2014) (deeming Heckler presumption overcome "if the agency has made clear its intent that a policy statement or set of enforcement guidelines impose binding limitations on the exercise of its enforcement discretion"). These decisions, however, have typically involved essentially procedural restraints with only incidental effects on substantive obligations and moreover have generally involved rules aimed at achieving broader enforcement and compliance rather than eliminating enforcement. See, e.g., id. at 1173-74 (reviewing whether agency complied with rules regarding enforcement following voluntary disclosure of aircraft maintenance issue but describing rule as "prescribing the agency's procedures, not its substantive standards for enforcing the regulations at issue"); Block v. SEC, 50 F.3d 1078, 1085 (D.C. Cir. 1995) (discussing rule requiring hearing in certain circumstances but deeming it inapplicable); Greater L.A. Council on Deafness, Inc. v. Baldrige, 827 F.2d 1353, 1361 (9th Cir. 1987) (requiring investigation following filing of complaint where regulation created "no ambiguity concerning the Department's duty to investigate a complaint"). But cf. Shell Oil Co. v. EPA, 950 F.2d 741, 765 (D.C. Cir. 1991) (deeming reasonable an agency rule precluding enforcement of legal requirements not included in permit under statute but noting agency's intent "to include all of the applicable statutory requirements in each permit and to enforce each permit fully").

Cir. 2014) (noting focus of analysis on "actual legal effect" of policy and whether the agency has applied it "as if it were binding on regulated parties"); Brock v. Cathedral Bluffs Shale Oil Co., 796 F.2d 533, 538 (D.C. Cir. 1986) (deeming enforcement policy a non-legislative rule because it was "replete with indications that the Secretary retained his discretion to cite production-operators as he saw fit" and gave regulated parties no reason to think that "failure to meet their responsibilities will, except in the instances described in the guidelines, categorically go unsanctioned"). For an argument that policy documents generally should avoid "fixed criteria" for decisions, see Robert A. Anthony, A Taxonomy of Federal Agency Rules, 52 Admin. L. Rev. 1045, 1047 (2000) ("The agency must treat the document as tentative and prospective, without present binding effect on private persons, and the agency must keep an open mind and be prepared to reconsider the policy as individual cases arise.").

(277) See id. at 384 (noting that "agencies often write [policy statements] in nonmandatory language to avoid having them struck down as legislative rules").

(278) The one caveat to this statement is that proceeding through notice and comment could elevate the level of deference the agency's interpretation of its statutory authority would receive. See Chevron U.S.A., Inc. v. Nat. Res. Def. Council, 467 U.S. 837, 845 (1984) (holding that courts should defer to reasonable agency interpretations of agency-administered statutes); United States v. Mead Corp., 533 U.S. 218, 226-27 (2001) (holding Chevron deference may not apply to policy documents adopted without notice and comment); City of Arlington v. FCC, 133 S. Ct. 1863, 1868 (2013) (holding that Chevron deference may apply to agencies' resolutions of "statutory ambiguity that concerns the scope of the agency's statutory authority").

(290) Some have argued the relevant violation occurs only at the point of unlawful entry or visa expiration and thus is not continuing. Cox & Rodriguez, supra note 63, at 199-200. While it is true that deterrence concerns may carry less weight with respect to undocumented immigrants who entered the United States long ago, the Supreme Court has characterized removal as a remedy for "an ongoing violation of United States law." Reno v. Am.-Arab Anti-Discrimination Comm., 525 U.S. 471, 491 (1999).

(291) Cox & Rodriguez, supra note 63, at 176 n.200 (recognizing policies as "novel").

(292) Reprehensible current political rhetoric in some quarters about the imperative of removing all undocumented immigrants fundamentally misunderstands the discretionary character of enforcement within the immigration system as it has evolved. Establishing priorities for enforcement of substantive laws is a basic and inevitable aspect of administration when full enforcement is impossible, and at least some degree of discretion should be presumed even when full enforcement is possible. The question DACA and DAPA present is whether their unusually definitive and prospective character, coupled with the ancillary changes in legal relations effected by granting deferred action, necessitates more specific legal authority than the sort of organic agency enforcement discretion that permits general priority-setting and that Heckler effectively insulates from judicial scrutiny.

(296) As noted, the current challenge to these policies presents additional issues, including ripeness and finality, that I do not attempt to resolve here. Nor do I take any specific position with respect to standing in immigration-related litigation, apart from tentative reflections on standing doctrine in general below. See infra Section III.D. In the Fifth Circuit, a dissenting judge further questioned whether the programs' substantive (as opposed to procedural) validity was properly before the court and whether the states had validly challenged the preexisting regulatory interpretation rendering deferred action recipients eligible for work authorization. Texas v. United States, 809 F.3d 134, 188 (2015) (King, J., dissenting).

(297) Because my aim here is to use these programs as examples of a type of action that should be reviewable despite Heckler, I assume here that the APA, as interpreted in Heckler, in fact governs review of DAPA and DACA. While the government has argued that a specific immigration statute bars review, see 8 U.S.C. [section] 1252(g) (2012) (denying jurisdiction over "any cause or claim by or on behalf of any alien arising from the decision or action by the Attorney General to commence proceedings, adjudicate cases, or execute removal orders against any alien under this chapter"), the Fifth Circuit deemed this provision inapplicable to APA challenges to the programs brought by states.

Why Industrial Animal Agriculture Is Not Beyond the Scope of Clean Air Act Regulation, 24 Pace Envtl. L. Rev. 439, 466-71 (2007).

(305) OLC Immigration Opinion, supra note 14, at 22-24 (noting the program "raise[s] particular concerns about whether immigration officials have undertaken to substantively change the statutory removal system rather than simply adapting its application to individual circumstances" and seeking guidance from "Congress's history of legislation concerning deferred action").

(306) See Cox & Rodriguez, supra note 63, at 191-93 (discussing difficulties controlling enforcement without programs).

(307) Whether this change should ultimately be attributed to the policies or the underlying regulation is a difficult issue that I do not attempt to resolve here. The key point here is that the interaction between the policy and the regulation gives this exercise of nonenforcement authority legal consequences that more conventional prosecutorial discretion--turning a blind eye to some violations so as to focus on others--does not.

(308) Admittedly, in this particular case, prior efforts to focus enforcement efforts through such internal guidelines proved ineffective, apparently because of recalcitrant defiance of the guidelines by low-level enforcement personnel. Cox & Rodriguez, supra note 63, at 191-93. Distressing as such disobedience is, it seems doubtful whether such internal managerial difficulties should affect an agency's ultimate legal authority to adopt a particular policy, though it might bear on whether the agency was otherwise "arbitrary and capricious" in doing so.

(309) OLC Immigration Opinion, supra note 14, at 24.

(310) Cox & Rodriguez, supra note 63, at 203 (arguing that in current immigration law "a perfect world is not a world of perfect enforcement" because "immigration law's formal prohibitions do not accurately reflect the structure of the immigrant screening system").

(311) Texas v. United States, 809 F.3d 134, 188 (2015) (King, J., dissenting).

(312) OLC Immigration Opinion, supra note 14, at 20-21.

(313) I have previously expressed skepticism about the legal authority for DACA, which OLC did not address in its opinion. Price, Enforcement Discretion, supra note 10, at 759-61; see OLC Immigration Opinion, supra note 14, at 18 n.8. For some theories supporting DACA, see Cox & Rodriguez, supra note 63 (de facto delegation); Martin, supra note 293 (emphasizing DACA group's small size and blamelessness). For an argument that authority for DAPA is lacking, see Peter Margulies, The Boundaries of Executive Discretion: Deferred Action, Unlawful Presence, and Immigration Law, 64 Am. U. L. Rev. 1183, 1194 (2015).

(314) In addition (or in the alternative), insofar as the rules establishing DAPA and DACA are procedurally valid without notice-and-comment procedures, the policies might properly be subject to more probing arbitrariness review than would be appropriate for more conventional nonenforcement policies. Mark Seidenfeld has proposed a framework for substantive review of guidance documents in general. He argues that "reasoned decision-making of guidance documents could mandate that agencies explain actions in terms of factors that are relevant and alternatives that are plausible given the state of knowledge available to the agency when it acted." Seidenfeld, supra note 53, at 388. Whether or not his proposal should apply more generally, it might carry particular force with respect to policies such as these, which in some sense constitute a peculiar hybrid between enforcement and substantive lawmaking. Again, even if DACA and DAPA could survive such scrutiny, AIR demonstrates its potential value in more conventional enforcement contexts where judicial review might help ensure the agency is acting in a manner reasonably calculated to bring about maximum eventual compliance with substantive law. Cf. Cox & Rodriguez, supra note 63, at 215-19 (highlighting "the basic failure of administrative law to address the central role that enforcement discretion plays in important regulatory arenas" and suggesting that some mechanism for ensuring public input short of notice-and-comment procedures would be desirable). The Fifth Circuit held that DAPA was procedurally invalid without notice-and-comment procedures. Texas, 809 F.3d at 177. For criticism of the view that DAPA is a legislative rule, see Cox & Rodriguez, supra note 63, at 216 & n.313.

(318) See Golumbic & Lichy, supra note 69, at 1300-01 (noting that "district courts routinely rubber stamp DPAs the same day they are presented for approval"). District judges have claimed authority to review DPAs' terms to a limited degree. United States v. Fokker Servs. B.V., 79 F. Supp. 3d 160, 167 (D.D.C. 2015), vacated and remanded, United States v. Fokker Servs. B.V., Nos. 15-3016, 15-3017, 2016 WL 1319266 (D.C. Cir. Apr. 5, 2016); United States v. Saena Tech. Corp., Crim. No. 14-66, 2015 WL 6406266, at *1 (D.D.C.

Circuit reversed one district-court decision rejecting a DPA. The appellate court held that the Speedy Trial Act "confers no authority in a court to withold exclusion of time pursuant to a DPA based on concerns that the government should bring different charges or should charge different defendants." Fokker Servs., 2016 WL 1319266, at *1. The court appeared to reserve questions about whether approval could be denied on other grounds. Id. at *8, *11 (declining to address "the precise contours of [the] authority of a court to confirm that a DPA's conditions are aimed to assure the defendant's good conduct" or whether "a court has authority to reject a DPA if it contains illegal or unethical provisions").

Defs. of Wildlife, 504 U.S. 555, 562 (1992) (noting difficulty of proving standing where "a plaintiff's asserted injury arises from the government's allegedly unlawful regulation (or lack of regulation) of someone else").

(332) See, e.g., Gene R. Nichol, Jr., Justice Scalia, Standing, and Public Law Litigation, 42 Duke L.J. 1141, 1160 (1993); Sunstein, supra note 224, at 167 (examining the constraint of the "concrete injury" requirement on standing). That is not to say that Congress should be able to give standing to itself. Legislative standing, even if provided for by statute, raises distinct concerns because it would force courts to directly referee inter-branch legal disputes, without any intermediation by a personally affected private litigant. See generally Tara Leigh Grove & Neal Devins, Congress's (Limited) Power to Represent Itself in Court, 99 Cornell L. Rev. 571, 573 (2014) ("Congress has the constitutional power to investigate the executive and judicially enforce subpoenas but ... it cannot defend federal statutes in court.").

(333) This claim draws from a rich line of argument, including, in particular, now Judge William A. Fletcher's classic article, The Structure of Standing, 98 Yale L.J. 221, 223-24 (1988).

(336) I take no position here on whether states have standing, either under current doctrine or my proposal, to challenge immigration nonenforcement policies, as they are attempting to do in current litigation. As a general matter, courts have taken a very narrow view of the interests protected by immigration statutes. Compare, e.g., Mendoza v. Perez, 754 F.3d 1002, 1018 (D.C. Cir. 2014) ("[W]orkers displaced by lax visa policies from jobs they otherwise would hold fall within the class of individuals whom the INA seeks to protect."), with Fed'n for Am. Immigration Reform, Inc. v. Reno, 93 F.3d 897, 902-03 (D.C. Cir. 1996) (doubting that Congress intended "universal litigative champions" for immigration restrictions), and Programmers Guild, Inc. v. Chertoff, 338 F. App'x 239, 244-45 (3d Cir. 2009) (following Fed'n for Am. Immigration Reform). Any asserted injury, furthermore, should be causally connected to the specific government action being challenged (here DAPA itself and not the mere presence of undocumented immigrants in the country).

(337) See, e.g., Erwin Chemerinsky, Interpreting the Constitution 96-101 (1987).

(338) The classic statement of this view is Henkin, supra note 86. For a more recent formulation of the argument, see Gwynne Skinner, Misunderstood, Misconstrued, and Now Clearly Dead: The "Political Question Doctrine" As a Justiciability Doctrine, 29 J.L. & Pol. 427, 428 (2014) ("[I]n nearly all cases involving a 'political question,' the Court has adjudicated the case by finding that the branch whose conduct was being challenged acted legally.").
