It is common for courts, the political branches, and academic commentators to look to historical governmental practices when interpreting the separation of powers. There has been relatively little attention, however, to the proper methodology for invoking such “historical gloss.” This Essay contends that, in order to gain traction on the methodological questions, we need to begin by considering the potential justifications for crediting gloss. For judicial application of gloss, which is this Essay’s principal focus, there are at least four such justifications: deference to the constitutional views of nonjudicial actors; limits on judicial capacity; Burkean consequentialism; and reliance interests. As the Essay explains, these differing justifications have differing methodological implications, and disaggregating them helps explain variations in the types of evidence that courts have credited in discerning gloss. Perhaps most notably, it helps explain why courts are often less demanding in requiring evidence of institutional acquiescence than commonly recited standards for gloss would tend to suggest.
I. Potential Justifications for Crediting Gloss
Any consideration of how to “do” an approach to law is inevitably intertwined with normative questions about the value of the approach, and that is true of the gloss approach to constitutional interpretation. This is not the place for a full normative evaluation of gloss, which would require not only an account of its potential benefits but also an assessment of its potential drawbacks. Nor does this Essay attempt to situate gloss more generally within constitutional theory, something that has been explored in other writings.26 Instead, the aim here is simply to describe the most likely justifications for crediting gloss in discerning the separation of powers, particularly in judicial decisions.27 A review of Supreme Court decisions and other materials that have invoked gloss suggests that there are at least four such justifications: deference to nonjudicial actors; limits on judicial capacity; Burkean consequentialism; and reliance interests. As will become apparent, probably the two most important, in terms of offering the most distinct visions about how to do gloss, are the deference justification and Burkean consequentialism.28
A. Deference to Nonjudicial Actors
The deference justification rests on the proposition that the courts do not have a monopoly on constitutional interpretation. Other governmental actors are sworn to uphold the Constitution, and they must of necessity interpret it as part of their duties.29 Moreover, with respect to separation-of-powers issues, political branch actors are likely to have a better understanding than courts of the practical consequences of particular constitutional interpretations. Furthermore, judicial deference to political branch understandings can reduce countermajoritarian concerns associated with constitutional judicial review, concerns that are especially strong when both political branches share a view that is different from the judiciary’s view, and have held that view for a long time. Giving weight to such views, this argument suggests, can be a way of making constitutional interpretation more democratically legitimate. For these reasons, this justification suggests that if the political branches have coalesced around a constitutional interpretation, and that understanding has persisted, it merits judicial deference.30
B. Limits on Judicial Capacity
A related justification for gloss concerns limits on judicial capacity. Sometimes courts invoke practice because other constitutional materials are perceived to offer insufficient guidance.31 This may be especially likely with respect to questions of executive power, given the limited textual guidance in Article II of the Constitution as well as substantial changes in the nature of the presidential office and international affairs over time.32 For such issues, unless the courts abstain altogether, relying on practice may offer the best option for a reasoned disposition of the case that seeks to avoid appealing simply to a policy assessment or “choosing a side” in a dispute between the branches. This justification for looking to gloss is consistent with the concept of “constitutional construction” articulated by some theorists, which envisions that interpreters can draw on various materials to resolve constitutional meaning “when the Constitution as written cannot in good faith be said to provide a determinate answer to a given question.”33
C. Burkean Consequentialism
The Burkean consequentialist justification rests on the premise that long-standing practices are suggestive of what works well, or at least what works better than anything the courts are likely to impose.34 These practices reflect the judgments of many actors over time, informed by the realities of governance and changes in the needs of governance, and therefore, the reasoning goes, they have the potential to embody collective wisdom. Under this rationale, the very persistence of a practice is evidence of its utility.35 In Noel Canning, for example, the Court claimed that the frequent and long-standing use of recess appointments “suggests that the Senate and President have recognized that recess appointments can be both necessary and appropriate in certain circumstances.”36
Burkean consequentialism also recognizes that long-standing practices are likely to be embedded within a broader array of understandings and institutional behavior, such that undoing them carries a risk of unforeseen consequences, including social and institutional disruption.37
That is, even if one is uncertain about the extent to which a particular practice is
optimal, the risks associated with unsettling the practice may outweigh any potential benefits that would be achieved. This idea, too, appears in the reasoning in Noel Canning. In explaining why it should not overturn long-standing practice relating to recess appointments, the Court observed: “We have not previously interpreted the Clause, and, when doing so for the first time in more than 200 years, we must hesitate to upset the compromises and working arrangements that the elected branches of Government themselves have reached.”38
D. Reliance Interests
A related justification, which concerns a particular type of consequentialist consideration, is one based on reliance interests. This idea, similar to one of the justifications for stare decisis,39 is that over time both governmental actors and third parties (including, potentially, society at large) are likely to have adjusted their behavior to account for persistent practices, and that they may have made decisions and concessions based on this reliance. The more long-standing and entrenched the practice becomes, the more likely it is that the practice will have such reliance effects. This justification can also be found in Noel Canning, most notably in the Court’s observation that it was “reluctant to upset this traditional practice where doing so would seriously shrink the authority that Presidents have believed existed and have exercised for so long.”40
* * *
In thinking about these potential justifications for crediting historical gloss, three additional points should be kept in mind. First, although these justifications are analytically distinct, they overlap and are potentially mutually reinforcing. For example, limits on judicial capacity can be a justification for deference to political branch interpretation, and also for the risk aversion associated with Burkean consequentialism. Moreover, the justifications are not mutually exclusive: it would not be inconsistent for an interpreter to invoke more than one justification—or even all of them—to justify resort to gloss. Nevertheless, as discussed below, it is possible to perceive differences in emphasis between the justifications offered by interpreters, in particular a difference in emphasis between justifications centered on deference and justifications centered on Burkean consequentialism.
Second, most if not all of the justifications assume that some amount of pragmatic reasoning is relevant to constitutional interpretation in the separation-of-powers area. As the Supreme Court explained (in somewhat-dated language) when relying on past governmental practice in United States v Midwest Oil Co,41 “government is a practical affair intended for practical men.”42 The more that one conceives of constitutional interpretation as a formal enterprise, involving merely the application of objectively identifiable textual meaning or original understanding, the less one will perceive the various justifications for gloss to be relevant. Not surprisingly, therefore, the Supreme Court decision best known for declining to credit gloss, Immigration and Naturalization Service v Chadha,43 is highly formal in its reasoning.44 Nevertheless, it should be noted that even Supreme Court justices known for their commitment to constitutional formalism have accepted the potential relevance of gloss under some circumstances.45
Third, another factor that is likely to affect the relevance of the above justifications for crediting gloss is the frequency of judicial review. Gloss argumentation thrives most when there is an absence of frequent judicial intervention, which is one reason it has been so common in the area of foreign affairs.46 When engaging in constitutional reasoning, courts are more likely to focus on their own precedent and reasoning rather than on nonjudicial practices, so extensive judicial interventions will tend to displace judicial reliance on gloss. Moreover, because of the tradition of judicial supremacy, political branch actors will typically coordinate around judicial decisions,47 so such decisions are likely to disrupt the ongoing development of practice. As a result, it is less likely in that situation that practices will become long-standing before they are challenged, and also less likely that they will generate reliance interests.48
II. Implications for Gloss Methodology
These differing justifications for gloss have differing implications for methodological questions concerning how to “do” gloss. This Part analyzes two such questions: what should count as “practice” when discerning gloss and whether a showing of institutional acquiescence should be required in order to establish gloss.
A. What Counts as “Practice”?
The historical gloss approach takes account of post-Founding governmental practice in discerning the separation of powers. But what precisely constitutes the “practice” of governmental institutions? Presumably it includes the enactment of statutes, which is the most obvious way in which Congress as an institution takes action. In United States v Curtiss-Wright Export Corp,49 for example, the Court gave weight to the fact that Congress had long enacted statutes giving broad foreign affairs authority to the president to support its conclusion that the delegation of criminalization authority in that case did not violate the separation of powers.50 Similarly, governmental practice also presumably includes presidential actions intended to have binding effect—for example, a directive that US troops engage in combat, the conclusion of an executive agreement, the appointment of officials during a Senate recess, or a declaration that the United States recognizes a particular foreign government.
There are a variety of additional congressional and executive branch materials, however, that take positions on separation-of-powers matters. For Congress, these materials include committee reports and nonbinding Senate and House resolutions. For the executive branch, they include legal memoranda (such as from the Office of Legal Counsel) and presidential signing statements. It is common for invocations of gloss to cite such materials,51 but there has been little express consideration of why they are relevant. If gloss concerns the iterative behavior of governmental institutions, one might think that the only relevant consideration is their actual behavior, not their verbal claims about their (or the other branches’) authority.52
The differing justifications for gloss yield potentially different answers. Because the deference justification is focused on the views of the political branches, it presumably would treat as relevant their articulations of those views, even if not accompanied by action. Indeed, their expression of constitutional views might be even more relevant than their actual behavior under this justification. Institutional behavior, after all, might be occurring for a variety of reasons other than a particular understanding of the Constitution.53 What is most important for deference is that the political branches, staffed by officials sworn to uphold the Constitution, have considered the issue and endorsed a particular constitutional interpretation.
There is, of course, an inherent danger of “cheap talk” when statements about the law are not accompanied by action. This danger, however, merely suggests that such statements should be considered with caution, not that they are irrelevant. Moreover, there might be evidence of the costliness of the statements even in the absence of practice—for example, if the statements are contrary to short-term political interests. It is also worth keeping in mind that, in some instances, expressions of views about the separation of powers that are made in the abstract are likely to be less opportunistic than ones made in the midst of controversy.
A wide range of materials could be relevant to discerning the constitutional understandings of the political branches. Even statements by individual members of Congress would potentially be relevant. Although such statements would not by themselves tell us the understanding of Congress as a whole (or even of a house of Congress or one of its committees), they could help reveal which constitutional propositions were generally taken for granted and which were disputed. Just as with resort to legislative history for interpreting statutes (which, although controversial, is commonplace), more weight should presumably be given to committee reports than to statements by individual legislators. Even greater weight could be given to congressional resolutions voted on by one or both houses of Congress—that is, to congressional “soft law.”54
As for the executive branch, greater weight could be given to internal legal reasoning (which later becomes public) than to public argumentation (such as that in signing statements), because the former would presumably reflect a more candid expression of views. And, again, expressions of constitutional views that are contrary to apparent political interests may be especially telling.
Another reason for looking to expressions of views by governmental officials stems from concerns about judicial capacity: it is difficult to know how to describe practice for purposes of making claims about gloss without considering how that practice is understood by its participants. As with all appeals to custom (and to judicial precedent55 ), there will inevitably be a question about the appropriate level of generality at which to describe the past practice, something that the practice itself cannot resolve. To help resolve this issue, it can be useful to look to how participants in the practice understand its generalizability, which requires looking to the claims they make about gloss and not just to their practice.
Nevertheless, some of the other justifications for gloss would place more weight on the actual behavior of institutions than on their stated views. For example, Burkean consequentialism treats as presumptively valid long-standing patterns of governmental conduct, but the same rationale would not necessarily apply to mere long-standing claims about the Constitution unsupported by conduct.56 The reliance justification falls somewhere in between: actual behavior is more concrete evidence that there has been reliance, but it is still possible that there will have been reliance, or institutional bargains, based on statements about the law.
If one is focused on institutional behavior, there is still a question of what constitutes behavior. In particular, there is a question about whether institutional inaction is a type of behavior. In theory, inaction could be relevant both for justifications focused on constitutional understandings and for justifications focused on patterns of behavior, although for different reasons.
Inaction in the face of action by another branch might be evidence of agreement with the constitutionality of that action, especially if there would otherwise be political incentives to contest the legality of the action. Similarly, if a branch considers acting and then refrains from doing so after legal claims are made against it, its inaction might suggest agreement with the claims. The Supreme Court relied on this sort of evidence in Zivotofsky, in support of an exclusive presidential power to recognize foreign sovereigns and their territory.57
Of course, there will often be potential explanations for inaction other than constitutional agreement, such as political calculation, institutional paralysis, or inattention, so this sort of evidence must be examined carefully.58 An institution’s failure to raise a constitutional objection to another branch’s practice should be given more weight when the institution is actively focused on the practice—for example, when it is opposing instances of the practice on policy grounds or is otherwise regulating in the area. Thus, in Noel Canning, the Court emphasized that even when the Senate was addressing issues relating to recess appointments in the twentieth century, it had not argued that it was unconstitutional for the president to make recess appointments during intrasession breaks or for vacancies that occurred prior to the break.59
Even when inaction does not show constitutional agreement, however, it could still show a pattern of institutional behavior and thus potentially be relevant to justifications that are not focused as much on shared constitutional understandings. In particular, inaction in the face of long-standing practice by another branch might confirm that the practice is stable or entrenched. This might help explain why the Court in Zivotofsky treated as relevant the lack of congressional regulation of recognition throughout much of the twentieth century without attempting to establish that this inaction was the result of a perception by Congress that it lacked authority to regulate.60
In evaluating the weight to be given to either expressions of constitutional views or behavior, another complication is that of party affiliation.61 A significant limitation on the idea that the political branches will act to safeguard their institutional interests—an idea associated most famously with James Madison’s Federalist 5162 —is the commitment of governmental actors to their political party. This means, for example, that a Congress controlled by the president’s political party is less likely to resist presidential incursions on congressional authority than one controlled, in whole or in part, by the opposition party.63 Congressional inaction in the face of presidential assertions of authority, therefore, is more probative when it occurs during periods of divided government, regardless of whether one is looking for common constitutional understandings or entrenched institutional practice. Conversely, congressional opposition is more probative when it comes from the president’s own party.
Whether focused on views or behavior, there is no precise metric for how long the practice must have persisted before being given weight as gloss. The deference justification would presumably require the least amount of time, given that the political branches could reach a common understanding about the Constitution in a relatively short period. Some of the other justifications, such as Burkean consequentialism and reliance interests, are, by contrast, likely to be focused on long-term accretions of practice. In Noel Canning, in which the Court was concerned about “upset[ting] the compromises and working arrangements that the elected branches of Government themselves have reached”64 and about “seriously shrink[ing] the authority that Presidents have believed existed and have exercised for so long,”65 the Court observed that “three-quarters of a century of settled practice is long enough to entitle a practice to ‘great weight in a proper interpretation’ of the constitutional provision.”66
In sum, determining what should properly count as “practice” depends in part on the justifications for gloss. In particular, justifications grounded in deference to political branch understandings are likely to credit a wide range of materials, including “soft law” materials, that help reveal such understandings. By contrast, Burkean justifications and justifications grounded in judicial capacity are likely to emphasize long-standing patterns of government action and inaction, even when it is not clear that the patterns are the result of constitutional understandings.
B. Must There Be Institutional “Acquiescence” in the Practice?
The Supreme Court has suggested in a number of decisions that, in order to establish gloss, it must be shown that the affected branch has “acquiesced” in the practice in question, and this is what Justice Frankfurter claimed in Youngstown.67 This claim is also common in academic commentary about gloss.68 The executive branch has been less committed to this proposition, sometimes contending that long-standing executive branch practice made under claim of right is sufficient to establish gloss.69
As with what counts as “practice,” whether acquiescence should be required, and the evidence that would be needed to establish it, will depend on the justifications for relying on gloss. As an initial matter, it is important to note that the idea of acquiescence could encompass a variety of interbranch relations. It could mean express agreement between the branches about a proposition of constitutional law.70 Or it could involve agreement about operational feasibility and desirability, as opposed to legality in a formal sense. Or it could mean simply a failure by one branch to resist claims of constitutional authority by another branch, for whatever reason.
The justification that most closely depends on a showing of acquiescence is the deference justification. If the claim is that the two political branches have long had a shared understanding of the separation of powers, the claim will require an especially strong form of acquiescence: actual interbranch agreement about the law. Mere long-standing practice and lack of resistance by another branch will not be sufficient.71
Importantly, though, even some variants of the deference rationale might not depend on a clear showing of acquiescence. In particular, if one branch has long articulated a constitutional view about the separation of powers and the other branch has been silent, it may not be clear whether there is any agreement between the branches. Nevertheless, the views of the branch that has maintained the position may still be entitled to some deference, especially if these views have been consistent and have reflected the views of both major political parties.72 After all, as Frankfurter observed in Youngstown, long-standing executive practice is “engaged in by Presidents who have also sworn to uphold the Constitution.”73 Similarly, in Noel Canning, the Supreme Court gave weight to the fact that “the publicly available opinions of Presidential legal advisers that we have found are nearly unanimous in determining that the [Recess Appointments] Clause authorizes” appointments during intrasession breaks.74
Moreover, even if it requires a showing of acquiescence, the deference justification would not necessarily require interbranch agreement about the constitutional text. Instead, it could be premised on the idea that part of constitutional reasoning is pragmatic (such as structural reasoning, as well as of course consequentialist reasoning), and that the political branches will have a better understanding than courts do of the operational feasibility and desirability of particular separation-of-powers arrangements. This idea seems to be reflected in the suggestion that is sometimes made by the Supreme Court and executive branch lawyers that gloss entails a “practical construction” of the Constitution.75 The more that we accept that constitutional interpretation involves an exercise in pragmatic judgment, the less we will require that the nonjudicial actors have formulated understandings about the text or original understanding of the Constitution, as opposed to what works well.
The other justifications for gloss have an even weaker connection to any requirement of acquiescence. For example, Burkean consequentialism might support looking to historical practice even in the absence of any evidence of acquiescence because of its focus on the value of established ways of doing things and a concern about the risks of change.76 Similarly, limits on judicial capacity might suggest deferring to practice even if it does not clearly reflect a common understanding of the political branches, because the practice can still provide a type of precedent external to a court’s preferences.
Once again, the reliance justification is uncertain: it is possible to imagine reliance occurring even in the absence of acquiescence, but it is also possible to insist that such reliance be “reasonable” before it will be credited, which may simply take us back to the initial question whether acquiescence is required in order for gloss to be credited. That said, disrupting even unreasonable reliance can pose concerns about institutional and social upheaval and unintended consequences of the sort that underlie some of the risk aversion associated with Burkean consequentialism.
In short, under many of the potential justifications for gloss, institutional acquiescence is less central than is commonly assumed. Importantly, however, even if one does not require a showing of acquiescence, there may be other reasons for insisting on some sort of subjective understanding in addition to looking to patterns of practice. As noted above, looking to such an understanding may be needed in order to determine the appropriate level of generality at which to describe the practice. In addition, resort to such an understanding may be needed to distinguish gloss from what Commonwealth theorists call “constitutional conventions,” which are “maxims, beliefs, and principles that guide officials in how they exercise political discretion.”77 Because both gloss and conventions concern practice-based norms of governmental conduct, it can be tempting to lump them together.78 But doing so misses an important difference between them: whereas conventions rest on either a fear of political sanctions or a sense of political morality,79 practice-based norms that amount to gloss also rest on claims about the content of constitutional law. Claims about gloss are claims about legal authority to act and the limits of such authority, and deviations are considered to be breaches not simply of political norms, but also of legal obligation. To be sure, appeals to gloss and to conventions sometimes overlap and can be difficult to distinguish, but this does not mean that they are analytically the same.
The need to distinguish gloss from conventions is greater when courts are applying gloss than when it is invoked by nonjudicial actors. In Congress, for example, those who invoke gloss can often afford to be vague or imprecise about the boundary between conventions and constitutional law—appealing, for example, to the “spirit” of the Constitution.80 A court attempting to resolve a dispute, however, will need to be more precise about what falls within and without the domain of binding constitutional law.81 Similarly, executive branch lawyers providing legal advice may need to distinguish gloss from conventions. Such lawyers are unlikely to find it sufficient, for example, to lump together the convention of senatorial courtesy for judicial appointments with, say, gloss-based norms about the constitutional authority of the president to wage war.
That said, it is important to remember that gloss is not typically invoked as a freestanding source of constitutional law. Instead, as the word “gloss” implies, it is treated as operating with and upon other modalities of interpretation, such as text, structure, purpose, and consequentialism.82 In part, this is a function of having a written Constitution and, relatedly, a constitutional culture that gives primacy to the text when it is perceived to be clear. This means, among other things, that historical practice is typically said to be relevant only when the constitutional text is ambiguous or silent on a question.83 In this respect, gloss is less imperialistic in its claims than some types of constitutional reasoning, such as some variants of textualism and originalism.
Because of the supplementary nature of gloss reasoning, there is less need for a subjective element for gloss than for something like customary international law, which is treated as a freestanding body of binding law.84 Thus, if an interpreter is inclined for reasons other than gloss to think that an institution should have a particular type of authority, gloss may be useful even if it merely shows that the practice can be viewed as consistent with that conclusion. This is one way to understand the Court’s decision in Zivotofsky: although it was unclear there whether the long-standing practice of presidential recognition of foreign governments was based on a shared constitutional understanding that Congress could not regulate the practice, the Court was able to cite the practice as at least not contradicting its determination of exclusivity—a determination based largely on the Court’s views about constitutional structure and consequences.85
To understand how to do gloss, it is important first to understand why one is doing it. As this Essay has explained, there are a number of possible justifications for doing gloss, and they have differing methodological implications. In particular, while justifications grounded in deference generally suggest looking for evidence of political branch understandings and agreement about the Constitution’s distribution of authority, justifications grounded in judicial capacity and Burkean consequentialism suggest looking primarily for stable patterns of institutional behavior. The implications of the reliance justification are more difficult to assess, in part because it may turn on contestable notions of when reliance is justified. Disaggregating the justifications in this way helps explain why, for example, courts often place less emphasis on institutional acquiescence than commonly recited standards for gloss would tend to suggest. Whatever the justification, gloss is almost always treated as interconnected with other constitutional considerations rather than as a fully independent source of law, a phenomenon that reduces some of the pressure for methodological precision.

- 63See Levinson and Pildes, 119 Harv L Rev at 2324 (cited in note 61) (observing that “the political interests of elected officials generally correlate more strongly with party than with branch”).

- 67See Youngstown, 343 US at 613 (Frankfurter concurring) (accepting that the “long-continued acquiescence of Congress” can “giv[e] decisive weight to a construction by the Executive of its powers”).
- 68See, for example, David J. Bederman, Custom as a Source of Law 111 (Cambridge 2010) (noting that for historical practice to inform interpretation of the separation of powers, one must ask “whether the opposing branch in the separation-of-powers struggle has actually accepted or ‘acquiesced’ in the practice”); Glennon, 64 BU L Rev at 134 (cited in note 52) (contending that the affected branch “must have acquiesced in the custom”).

Glennon, The Cost of “Empty Words”: A Comment on the Justice Department’s Libya Opinion *3 (Harvard National Security Journal 2011), archived at http://perma.cc/VA76-E2Y3 (contending that, although “practice can affect the Constitution’s meaning and allocation of power,” “[a] practice of constitutional dimension must be regarded by both political branches as a juridical norm” before it does so).
- 71For one articulation of this position, see Roisman, 84 Geo Wash L Rev at 710 (cited in note 53) (proposing that the only historical practice that should be credited is that which “is likely to be indicative of constitutional agreement between the branches”).
- 72See Bradley and Morrison, 126 Harv L Rev at 460 (cited in note 1). See also, for example, Office of Legal Counsel, Authority to Use Military Force in Libya at *7 (cited in note 15) (stressing that the war powers practice not only “extended over many decades” but was also “engaged in by Presidents of both parties”).

- 81This distinction between judicial decision-making and political branch reasoning should not be overstated, however. Courts, too, are sometimes imprecise about the boundary between constitutional and subconstitutional norms, such as when they construe statutes to avoid “serious constitutional doubts.” See, for example, Jones v United States, 526 US 227, 239 (1999) (referring to “the rule, repeatedly affirmed, that where a statute is susceptible of two constructions, by one of which grave and doubtful constitutional questions arise and by the other of which such questions are avoided, our duty is to adopt the latter”) (quotation marks omitted).
- 82See, for example, Zivotofsky, 135 S Ct at 2091, 2094 (contending that “on balance [historical practice] provides strong support for the conclusion [based on text, judicial precedent, and consequentialist considerations] that the recognition power is the President’s alone,” and that this practice “confirms the Court’s conclusion”); Noel Canning, 134 S Ct at 2561, 2570 (contending that historical practice “offers strong support” and “strongly favors” constructions of the Recess Appointments Clause that the Court otherwise found persuasive based on considerations of purpose and consequentialism).
- 83See LaCroix, 126 Harv L Rev F at 81 (cited in note 23) (“[H]istorical practice is relevant only in situations where the interpreter has first determined that text is unclear or ambiguous.”); Noel Canning, 134 S Ct at 2561, 2568 (insisting that the relevant constitutional provisions were ambiguous). But see Curtis A. Bradley and Neil S. Siegel, Constructed Constraint and the Constitutional Text, 64 Duke L J 1213, 1262 (2015) (contending that perceptions of textual clarity and ambiguity can themselves be affected by historical practice and other considerations).
- 84See Restatement (Third) of the Foreign Relations Law of the United States § 102, comment j (1987) (“Customary law and law made by international agreement have equal authority as international law.”). This is one reason for hesitation before drawing on theoretical work relating to customary international law to inform thinking about gloss. But see Glennon, 64 BU L Rev at 134 (cited in note 52) (borrowing the concept of opinio juris from customary international law); Roisman, 84 Geo Wash L Rev at 675 (cited in note 53) (analogizing gloss to customary international law). See also Vermeule, 38 Dublin U L J at 288–89 (cited in note 78) (analogizing to customary international law when discussing constitutional conventions).
- 85See Zivotofsky, 135 S Ct at 2094 (“This history confirms the Court’s conclusion in the instant case that the power to recognize or decline to recognize a foreign state and its territorial bounds resides in the President alone.”); Curtis A. Bradley, Agora: Reflections on Zivotofsky v. Kerry; Historical Gloss, the Recognition Power, and Judicial Review, 109 Am J Intl L Unbound 2, 6 (2015), archived at http://perma.cc/CMY4-VJZS (“The post-nineteenth century practice concerning recognition was dominated by the executive branch, and this fact helped to reinforce the Court’s finding of exclusivity, even though it was not by itself sufficient to sustain that conclusion.”).
