In 2023, Congress enacted a law that prohibits the President from "suspend[ing], terminat[ing], denounc[ing], or withdraw[ing] the United States from the North Atlantic Treaty"—which established the North Atlantic Treaty Organization (NATO)—without the advice and consent of the Senate or an act of Congress. See Section 1250A of the 2024 National Defense Authorization Act, Pub. L. No. 118-31. This provision emerged against the backdrop of debates concerning the United States' policy toward NATO and whether the President possesses the power to withdraw the United States from treaties without receiving the legislative branch's approval.
Prior to Section 1250A's enactment, the Department of Justice's Office of Legal Counsel (OLC) published an opinion in 2020 concluding that the President has exclusive power over treaty withdrawal and that Congress is constitutionally prohibited from intruding upon this power. In contrast to the OLC's legal position, which neither courts nor Congress are bound to consider as authoritative, Section 1250A's sponsors stated that the legislation "ensures that no President can unilaterally dissolve our bond to this invaluable alliance without Senate approval." If the President decided to unilaterally withdraw from the North Atlantic Treaty, irrespective of Section 1250A, there are at least two ways in which the statute might affect a court's analysis of any challenge to the President's action. First, the statute may influence a court's decision on whether to hear such a challenge at all, and second, the statute could affect the court's evaluation of the President's action in the event it decides to hear a case.
With respect to whether a court would hear a challenge, two doctrines are relevant: the political question doctrine and standing. Historically, courts have generally left the issue of the constitutional distribution of treaty-withdrawal power to the political branches, concluding that challenges to unilateral treaty withdrawal by the President present a nonjusticiable political question. See, e.g., Goldwater v. Carter, 444 U.S. 996, 1003 (1979). More recent Supreme Court jurisprudence suggests that courts may be less likely to dismiss a challenge to a President's withdrawal from the North Atlantic Treaty in violation of Section 1250A on political question grounds. In a case involving another question of separation of foreign policy powers, the Court held that, where a President acts contrary to a statute on the ground that it interferes with the President's Article II authority, the constitutional question is one properly resolved by the judiciary rather than left to the political branches. See Zivotofsky ex rel. Zivotofsky v. Clinton, 566 U.S. 189, 196 (2012).
Another issue is who would have standing to bring a legal challenge to an alleged violation of Section 1250A. This doctrine may present greater hurdles than the political question doctrine, as it would ultimately depend on whether the plaintiff is able to allege that they suffered an injury that meets the standards the Supreme Court has established—i.e., that the injury is unique to them rather than shared by the general population, is sufficiently tied to the alleged violation, and is redressable by a court. See Lujan v. Defenders of Wildlife, 504 U.S. 555, 560−61 (1992). In the past, courts have often found that plaintiffs, including Members of Congress, fail to meet one or more of these requirements in cases involving foreign policy issues, including that of treaty withdrawal. See, e.g., Kucinich v. Bush, 236 F. Supp. 2d 1, 18 (D.D.C. 2002).
In the event that a court were to hear a challenge to a President's unilateral withdrawal from the North Atlantic Treaty, it may likely apply the well-established framework for analyzing separation of powers issues derived from Justice Robert Jackson's concurring opinion in Youngstown Sheet & Tube Co. v. Sawyer, 343 U.S. 579 (1952). If a court were to determine that a President's withdrawal was contrary to a congressional prohibition, it may conclude that the action could be upheld only if the President has exclusive authority, a claim that the Youngstown framework instructs courts to "scrutinize[] with caution." Zivotofsky ex rel. Zivotofsky v. Kerry 576 U.S. 1, 10 (2015). In assessing whether such authority exists, a court might draw on the Constitution's text and structure as well as other relevant judicial precedent. Courts also often consider the historical practice of the political branches in separation of powers cases. See id. at 23. During the 19th century, the political branches often treated the treaty withdrawal power as a shared one in which both Congress and the President played a role. In the 20th century, the executive branch increasingly asserted independent authority to withdraw from treaties, and Congress periodically regulated U.S. participation in treaties. The executive branch does not appear to have asserted a claim of exclusive presidential authority until the 2020 OLC opinion, and Section 1250A appears to be the first statutory prohibition of unilateral presidential withdrawal from a treaty. Ultimately, given the absence of directly controlling judicial precedent, in a case challenging a Section 1250A violation, both parties would be able to present arguments in support of their positions.
The Constitution expressly sets forth the roles of Congress and the Executive in the making of treaties, but is silent on the matter of treaty withdrawal.1 During the 19th century, the legislative and executive branches often treated the treaty withdrawal power as a shared one in which both branches played a role.2 In the 20th century, the executive branch increasingly asserted independent authority to withdraw from treaties, and Congress, periodically and to varying extents, regulated U.S. participation in treaties.3
In 2023, Congress passed, and the President signed into law, the first statute prohibiting the President from unilaterally withdrawing from a Senate-approved treaty. Section 1250A of the 2024 National Defense Authorization Act4 (2024 NDAA) prohibits the President from "suspend[ing], terminat[ing], denounc[ing], or withdraw[ing] the United States from the North Atlantic Treaty"5—which established the North Atlantic Treaty Organization (NATO)6—without the advice and consent of the Senate or an act of Congress.7 This statute is in tension with the position taken by the Department of Justice's Office of Legal Counsel (OLC) in a 2020 opinion maintaining the President has authority to withdraw the United States from treaties without congressional approval, and that this authority is exclusive to the presidency.8 The OLC's claim of exclusive presidential authority over treaty withdrawal appears to go beyond the executive branch's long-standing position that the President had independent authority to withdraw from treaties absent congressional restriction.9
Prior to the enactment of Section 1250A, reviewing courts generally decided that challenges to unilateral treaty withdrawal by the President presented a nonjusticiable political question—meaning that the issue needed to be resolved by the politically accountable legislative and executive branches rather than in the courts.10 The OLC's 2020 opinion provided the executive branch's response to this question; in Section 1250A, Congress provided a different response in the context of a specific treaty—the North Atlantic Treaty. If a President were to withdraw from the North Atlantic Treaty without congressional approval as required by Section 1250A, and a challenge were brought that a court agreed to hear, the executive branch might argue, consistent with the 2020 OLC opinion, that Section 1250A interferes with the President's exclusive authority to withdraw from treaties and is thus unconstitutional.11
This report examines the issues that U.S. courts could potentially address if a President were to assert the authority to withdraw unilaterally from the North Atlantic Treaty notwithstanding Section 1250A. It begins by providing the background and legal framework governing the process for treaty withdrawal at the international and U.S. domestic levels. Next, this report examines historical practices related to treaty withdrawal, which began as a cooperative, interbranch process, but has evolved into sometimes conflicting legislative and executive branch positions. This report then analyzes how a court might determine whether it could hear a challenge to an alleged violation of Section 1250A by applying the political question or standing doctrines. This report next analyzes how courts might approach the question of whether Section 1250A violates constitutional separation of powers principles if they were to agree to hear a challenge to a President's unilateral withdrawal from the North Atlantic Treaty. Finally, this report proffers some considerations for Congress as it continues to exercise its legislative and oversight authorities related to treaties.
Treaties operate under separate international and domestic legal frameworks, and these frameworks create distinct sets of rules governing how countries enter into, perform, and withdraw from treaties.12 Generally, under international law, a nation's head of state has authority to withdraw from a treaty, provided the treaty permits withdrawal and the specified withdrawal process is followed.13 Article 13 of the North Atlantic Treaty permits parties to withdraw one year after providing a "notice of denunciation."14 Under U.S. domestic law, the legal rules governing treaty withdrawal are less straightforward and have been the subject of changing practices and interpretation, as discussed in the following sections.
Article II of the Constitution sets forth a specific procedure through which the President has the power to make treaties with the advice and consent of the Senate,15 but is silent as to how treaties may be terminated. Both Congress and the President possess other constitutional powers related to foreign affairs, which complicates the analysis of where the power to terminate treaties resides.
Article I of the Constitution grants Congress several foreign-affairs-related powers, including the power to declare war; establish, fund, and regulate federal armed forces; regulate commerce with foreign states; "provide for the common Defence"; "define and punish violations of the law of nations"; "grant Letters of Marque and Reprisal"; "make Rules concerning Captures on Land and Water"; and "make all laws which shall be necessary and proper for carrying into Execution . . . all . . . Powers Vested by this Constitution in the [federal] government."16 Article II vests the "executive Power" in the President, makes the President "Commander in Chief" of the armed forces, and authorizes the President to "receive Ambassadors and other public Ministers . . . ."17
Apart from these textual sources, the Supreme Court has stated that both the executive and legislative branches have broad powers over foreign affairs that are not limited to "affirmative grants of the Constitution."18 With regard to the President, the Court has further suggested that such inherent foreign affairs authority includes certain powers inherent in the role as head of a sovereign state that appear not to be shared with the legislative branch, such as "the power to speak or listen as a representative of the nation."19 Although the Court recognized this presidential "power to act in foreign affairs does not enjoy any textual detail" in Article II, it determined that the President's "executive power" under Article II includes the "vast share of responsibility for the conduct of our foreign relations."20
At the same time, the Court has also recognized that the legislative branch has a role in foreign affairs, emphasizing that Presidents are "not free from the ordinary controls and checks of Congress merely because foreign affairs are at issue."21 The Court has further explained that Congress's role in foreign affairs must "be understood and respected," because only Congress holds the power to make the law regarding both domestic and foreign matters.22
Applying these principles to treaty withdrawals, scholars generally accept that Presidents, by virtue of their "unique role in communicating with foreign governments,"23 are responsible for communicating the United States' intention to withdraw from a treaty.24 Beyond that act of communication, however, there is long-standing debate over which branch (or branches) of government have the power to decide that the United States will withdraw from a treaty as a matter of U.S. domestic law. In particular, the degree to which the Constitution contemplates a role for the legislative branch to participate in treaty withdrawal decisions has been the source of changing practices and disagreement among the legislative and executive branches and legal scholars.
The past practices related to treaty termination have varied over the years.25 The first time that the United States terminated a treaty after the Constitution was ratified was in 1798. On the eve of possible hostilities with France, Congress passed, and President Adams signed, legislation stating that four U.S. treaties with France "shall not henceforth be regarded as legally obligatory on the government or citizens of the United States."26 Thomas Jefferson referred to the episode as support for the notion that only an "act of the legislature" can terminate a treaty;27 however, many commentators since have come to view this 1798 statute as a historical anomaly because it is the only instance in which Congress purported to terminate a treaty directly through legislation without relying on the President to provide a notice of termination to the foreign government.28 Moreover, because the 1798 statute was part of a series of congressional measures authorizing limited hostilities against the French Republic, some view the statute as an exercise of Congress's war powers rather than precedent for a congressional power to terminate treaties.29
During the 19th century, the general practice was to treat the power to terminate treaties as shared between the legislative and executive branches.30 Congress often authorized31 or instructed32 the President to provide notice of treaty termination to foreign governments during this time. On rare occasions, the Senate alone passed a resolution authorizing the President to terminate a treaty.33 Presidents regularly complied with the legislative branch's authorization or direction. For example, after Congress enacted a joint resolution calling for the termination of the Oregon Territory Treaty, then-Secretary of State (and future President) James Buchanan informed the U.S. Ambassador to Great Britain that "Congress have spoken their will upon the subject, in their joint resolution; and to this it is his (the President's) and your duty to conform."34 On other occasions, Congress or the Senate approved the President's termination after-the-fact, when the executive branch had already provided notice of termination to the foreign government.35
At the turn of the 20th century, the practice regarding treaty termination began to change, and a new form emerged: unilateral termination by the President without approval by the legislative branch. This method first occurred in 1899, when the McKinley Administration terminated certain articles in a commercial treaty with Switzerland,36 and again in 1927, when the Coolidge Administration withdrew the United States from a convention with Mexico regarding the prevention of smuggling.37 Some Members of Congress questioned the constitutionality of this practice,38 and the executive branch acknowledged in a 1909 memorandum that joint action between the President and Congress was the more "effective and unquestionable" method to terminate a treaty.39 Despite these mixed views, unilateral presidential termination increased during the Franklin Roosevelt Administration and World War II.40 Over the course of the 20th century, unilateral presidential termination generally became the norm41—both for treaties that contain withdrawal clauses and those that do not.42
While the U.S. practice since the turn of the 20th century has trended toward unilateral presidential treaty withdrawal, the practice has not been uniform. Congress has enacted legislation authorizing or instructing the President to terminate treaties and other international agreements,43 and there are a number of cases in which Presidents relied upon and complied with these congressional directives.44 Members of Congress have also occasionally raised constitutional objections to the President's unilateral treaty withdrawal.45 In 2019, Congress enacted legislation requiring the President to notify Congress at least 120 days before withdrawing the United States from the Treaty on Open Skies.46 In 2020, President Trump notified the treaty parties of the United States' intent to withdraw without complying with the statutorily required 120-day congressional notice period.47 As discussed below, the OLC argued in a 2020 opinion that this statutory notice requirement was an unconstitutional infringement on the President's exclusive power to withdraw from treaties.48 Most unilateral withdrawals have not generated congressional opposition, and Congress did not enact legislation or a resolution formally opposing the President's withdrawal from a particular treaty until it enacted Section 1250A in 2023; however, some Members have filed suit challenging the constitutionality of unilateral withdrawal.49 As discussed in more detail below, courts thus far have dismissed these challenges on justiciability grounds without reaching the merits of the constitutional question.50
Government officials in the legislative and executive branches and scholars have expressed differing views about the branches' respective roles in treaty termination. Some have argued that the President possesses the powers to withdraw unilaterally from treaties based on Supreme Court case law describing the President as the "sole organ"51 of the nation in matters related to foreign affairs52 and pursuant to the "executive Power" conveyed to the President in Article II, Section 1 of the Constitution.53 Other proponents of executive authority have likened the power to withdraw from treaties to the President's power to remove executive officers.54 Although the Appointments Clause requires senatorial advice and consent for the appointment of certain executive officers, the Supreme Court has held that the President has significant unilateral authority to remove those officers.55 The Treaty Clause immediately precedes the Appointments Clause, and some executive branch officials and legal scholars have argued the same principles that allow the President to undo appointments that are made with the Senate's consent support the view that the President may unilaterally terminate treaties, which are also entered into with the Senate's consent.56
Since the turn of the 20th century, officials in the executive branch have adopted variations of these arguments and consistently taken the position that the Constitution permits the President to withdraw from treaties without receiving express approval from the legislative branch.57 The prevailing view among foreign relations law scholars appears to be that the President may unilaterally withdraw from treaties if it is permitted by the treaty or other international laws and Congress has not expressly prohibited it.58
Some Members of Congress and a smaller group of observers have advanced a more limited view of presidential power, arguing that the Constitution requires the legislative branch's approval for the President to withdraw from a treaty that received the Senate's advice and consent. According to these advocates for a congressional role, treaty termination should be considered analogous to the termination of federal statutes because the Supremacy Clause includes both treaties and statutes as sources of the "supreme Law of the Land."59 Thus, those advancing this view reason that, because domestic statutes may be terminated only through the same process in which they were enacted—i.e., through a majority vote in both houses and with the signature of the President or veto override60—treaties must be terminated through a procedure that is symmetrical to their making and that includes, at a minimum, the Senate's consent.61
Although there was little direct discussion of the treaty termination power at the Constitutional Convention,62 some documents from the early constitutional era arguably support the view that the legislative branch should participate in treaty withdrawal.63 In a 1791 letter, James Madison questioned whether a treaty with Great Britain could be terminated by the President and Senate or whether the "whole Legislature" must participate in its annulment—but he did not mention the possibility of unilateral termination by the Executive.64 In Ware v. Hylton, a 1796 Supreme Court decision concerning the legal effect of treaties on conflicting state laws, one Justice expressed the view that only Congress has the ability to declare a treaty void as a result of a breach.65 In his Manual of Parliamentary Practice, Thomas Jefferson wrote in 1801 that "[t]reaties being declared, equally with the laws of the United States, to be the supreme law of the land, it is understood that an act of the legislature alone can declare them infringed and rescinded."66
Proponents of executive authority have responded to this proposition by arguing that the Supremacy Clause's purpose was to establish the primacy of treaties and federal statutes over state law—not to deem treaties and statutes identical in all respects.67 In addition, they argue, treaties do not share every feature of federal statutes.68 Whereas statutes can be enacted over the President's veto, treaties can never be concluded without the Senate's advice and consent.69 Moreover, when exercising its veto-override power, Congress is the final actor in making U.S. domestic laws. In the treaty-making process, however, the President must take the final step in committing that the United States will be bound by the terms of the treaty by submitting a signed instrument of ratification after the Senate provides its advice and consent.70
In a 2020 opinion from the Department of Justice's OLC, the executive branch publicly took the view, for what appears to be the first time,71 that the President's authority to withdraw from treaties is an exclusive presidential power that Congress cannot restrict through legislation.72 The opinion addressed a statutory provision that required the President to provide notice to Congress at least 120 days before notifying the other state parties that the United States intended to withdraw from the Treaty on Open Skies.73 Contending that congressional control of treaty withdrawal interferes with the President's "exclusive authority to execute treaties and to conduct diplomacy," OLC concluded that the statutory requirement of a congressional-notice period was unconstitutional.74 Deciding whether to withdraw from a treaty is a "quintessentially executive" choice that is committed to the President's discretion, OLC opined.75 Although not binding on courts or Congress,76 OLC legal opinions have historically been treated as binding within the executive branch.77
Following the United States' withdrawal in contravention of the statutory notice requirement,78 some Members of Congress expressed criticism of the executive branch's decision not to comply with the congressional notification requirement,79 and bill text was introduced expressing the sense of Congress that the withdrawal violated federal law, but that text was not enacted.80 In addition, Congress did not take any formal action after the withdrawal.
In what might be understood as a rejection of the executive branch's position that the President possesses exclusive power over treaty withdrawal, in 2023, Congress enacted what appears to be the first statute prohibiting the President from unilaterally withdrawing from a treaty (specifically, the North Atlantic Treaty).81 Section 1250A of the 2024 NDAA provides that the President "shall not suspend, terminate, denounce, or withdraw the United States from the North Atlantic Treaty" without the advice and consent of the Senate, with two-thirds of Senators present concurring, or pursuant to an act of Congress.82 Additionally, the statute prohibits use of appropriated funds to withdraw from the North Atlantic Treaty without the advice and consent of the Senate, with two-thirds of Senators present concurring or pursuant to an act of Congress.83 Section 1250A also requires the President to consult with the House and Senate foreign affairs committees "in relation to any initiative" to withdraw the United States from the North Atlantic Treaty, and to notify those committees "of any deliberation or decision" to withdraw from the North Atlantic Treaty "as soon as possible but in no event later than 180 days prior to taking such action."84 To date, the 2020 OLC opinion has not been withdrawn, suggesting that the executive branch may maintain that the President has exclusive treaty withdrawal power, including power to unilaterally withdraw from the North Atlantic Treaty.85

Changing Practice in Treaty Withdrawal Paradigms The United States' treaty withdrawal practice can be summarized in several key events and stages. Congressional Termination (1798). The United States' first treaty withdrawal after the Constitution's adoption took place pursuant to legislation stating that four treaties "shall not henceforth be regarded as legally obligatory on the government or citizens of the United States."86 Shared Withdrawal Power (19th century). Treaty withdrawal was treated as a shared power between the legislative and executive branches, and both branches authorized or approved withdrawal.87 Shift to Unilateral Presidential Power (20th century to present). Unilateral withdrawal by the executive branch becomes the predominant practice.88 Claim of Presidential Exclusivity (2020). In an OLC opinion, the executive branch claimed exclusive constitutional authority to withdraw from treaties and asserted that Congress cannot limit or condition this power in legislation.89 Congressional Rejection of Presidential Exclusivity (2023). In Section 1250A of the 2024 NDAA, Congress provided that the President cannot withdraw from the North Atlantic Treaty without congressional or Senatorial consent.90 |
Before addressing the constitutional analysis that a court would likely apply in a case involving a challenge to a President's withdrawal from the North Atlantic Treaty, there is the initial question of whether a court would intervene in the first place or instead deem the issue improper for judicial resolution based on one or more justiciability doctrines. Many cases involving issues of foreign affairs face significant justiciability hurdles that often have led courts to decline to weigh in on the merits. Two of the principal justiciability doctrines that have resulted in dismissal of cases involving foreign affairs, including challenges to a President's unilateral withdrawal from treaties, are the political question and standing doctrines.91 Both doctrines are based on the separation of powers between federal courts and the political branches; the Supreme Court has developed the law governing each based on its interpretation of the scope of judicial power granted in Article III of the Constitution.92 If a President sought to withdraw from the North Atlantic Treaty, but did not obtain approval through the advice and consent of the Senate or an act of Congress, it is possible that the executive branch would invoke the political question and standing doctrines as bases to dismiss any lawsuits seeking to enforce Section 1250A.
The Supreme Court developed the political question doctrine based on its determination that Article III grants the judicial branch the power to decide "cases" and "controversies,"93 and this power precludes courts from deciding so-called "political questions"—a term that the Court uses to refer to questions that are reserved to the political branches.94 In the 1962 case Baker v. Carr,95 the Supreme Court articulated a factor-based analysis for courts to use in determining whether a case presents a political question.
|
The Baker v. Carr Factors Under Baker v. Carr, political questions might involve the following features:
|
Although courts have frequently dismissed cases involving foreign policy issues on the ground that they present a political question, courts generally state that they arrive at those conclusions based on the Baker analysis rather than based on the mere fact that the case involves foreign policy.97 As the Supreme Court stated in Baker, the political question doctrine "is one of 'political questions,' not one of 'political cases'";98 thus, "it is error to suppose that every case or controversy which touches foreign relations lies beyond judicial cognizance."99
In the most prominent treaty-withdrawal case to date and the only one that has reached the Supreme Court—Goldwater v. Carter100—a plurality of the Justices concluded that dismissal was appropriate based on the political question doctrine.101 That case arose during the 1970s when the executive branch was pursuing closer relations with the government of the People's Republic of China (PRC).102 Anticipating that, as part of its efforts to normalize relations with the PRC, the executive branch might terminate the 1954 Mutual Defense Treaty with the government of Taiwan,103 Congress enacted the International Security Assistance Act, which, among other things, expressed "the sense of the Congress that there should be prior consultation between the Congress and the executive branch on any proposed policy changes affecting the continuation in force of the Mutual Defense Treaty of 1954."104 When the Carter Administration announced that the United States would provide notice to Taiwan of its intent to terminate the treaty without having first obtained congressional consent,105 some Members of Congress filed a lawsuit seeking to block the President's action on the ground that the President lacked the constitutional authority to unilaterally terminate the treaty.106
The U.S. District Court for the District of Columbia and the U.S. Court of Appeals for the District of Columbia both held that the suit was justiciable, but they came to opposite conclusions on the merits. While the district court determined that the treaty power was a shared one and thus the President's unilateral withdrawal was unconstitutional,107 the appellate court reversed based on its holding that the President's unilateral withdrawal from the particular treaty at issue was constitutional based on the circumstances involved in the case.108 The Supreme Court granted the Members of Congress's petition for a writ of certiorari, but did not reach the merits of the constitutional question.109 Instead, in a divided opinion, the Court vacated the appellate court's decision and remanded the case to the district court with instructions to dismiss the complaint.110
Writing for a four-Justice plurality, Justice Rehnquist concluded that the case should be dismissed because the constitutional question over treaty withdrawal was a nonjusticiable political question.111 In reaching this conclusion, the plurality relied primarily on the second Baker factor—a lack of judicially discoverable and manageable standards for resolving" the case.112 The plurality reasoned that, because the Constitution did not expressly address treaty withdrawal and because "different termination procedures may be appropriate for different treaties," the issue presented by the case was governed by "political" rather than judicial standards.113 Justice Powell concurred in the judgment for dismissal, but on the ground that the case was not ripe for judicial review as Congress had not taken any "formal action" disputing the President's authority to terminate the treaty.114 According to Justice Powell, if Congress had done so, "it would be the duty of this Court to resolve the issue."115
Since the Goldwater decision, Justice Rehnquist's plurality opinion has proven influential among some lower federal courts, which have cited the decision in dismissing challenges to Presidents' unilateral withdrawals from treaties on political question grounds.116 While courts—and perhaps ultimately the Supreme Court—might find the Goldwater plurality's reasoning to be persuasive in a case challenging a President's unilateral withdrawal from the North Atlantic Treaty in violation of Section 1250A, there is a potentially legally significant distinction between Goldwater and a case involving a violation of Section 1250A; namely in Goldwater, there was no statute prohibiting the President's unilateral withdrawal from the U.S.-Taiwan Mutual Defense Treaty. In providing the fifth vote for dismissal, Justice Powell maintained that the case would have been appropriate for judicial resolution had there been such a statute prohibiting unilateral withdrawal.117
The Supreme Court's more recent political question jurisprudence might also influence whether a court addressing a Section 1250A case would reach the same result as the Goldwater plurality. In particular, a 2012 decision addressing whether a case involving separation of foreign policy powers presented a political question suggests that a statutory prohibition of the challenged presidential action might make a difference in a reviewing court's application of the Baker factors. That case—Zivotofsky ex rel. Zivotofsky v. Clinton (Zivotofsky I)118—involved a challenge to the State Department's refusal to comply with a statute requiring the Department to record in a passport the birthplace of U.S. citizens born in Jerusalem as "Israel" if requested by the citizen or the citizen's guardian.119 According to the State Department, its long-standing policy of recording the birthplace as "Jerusalem" on passports reflected the executive branch's decision to leave the question of the sovereign status of Jerusalem as a matter to be resolved in diplomatic negotiations.120 The government argued that this policy was based on the President's exclusive power to recognize foreign states and that the statutory requirement impermissibly infringed on that power.121
The U.S. District Court for the District of Columbia and the U.S. Court of Appeals for the D.C. Circuit (D.C. Circuit) agreed with the executive branch that the case presented a political question requiring dismissal,122 but the Supreme Court reversed in an eight-Justice majority opinion that focused on the first two Baker factors.123 In concluding that the first factor—a textually demonstrable constitutional commitment of the issue to a coordinate political department—did not apply, the majority reasoned that the case required a determination of whether a statute was constitutional, which "is a decision for the courts."124 According to the majority:
[F]ederal courts are not being asked to supplant a foreign policy decision of the political branches with the courts' own unmoored determination of what United States policy toward Jerusalem should be. Instead, Zivotofsky requests that the courts enforce a specific statutory right. To resolve his claim, the Judiciary must decide if Zivotofsky's interpretation of the statute is correct, and whether the statute is constitutional. This is a familiar judicial exercise.125
The majority also found that the fact the case presented the question of the constitutionality of a statute was relevant in concluding that the second Baker factor—a lack of judicially discoverable and manageable standards for resolving the issue presented by the case—did not apply. Specifically, the Court observed that the issue of whether the passport statute impermissibly infringed on the President's constitutional powers required "careful examination of the textual, structural, and historical evidence put forward by the parties regarding the nature of the statute and of the passport and recognition powers," which "is what courts do."126
Zivotofsky I arguably supports a claim that a challenge to any alleged violation of Section 1250A does not present a political question. As to the first factor, an alleged violation of Section 1250A would involve a President's refusal to comply with a statutory directive, and thus "the only real question for the courts [would be] whether the statute is constitutional"—a question that the Zivotofsky I Court emphasized was constitutionally committed to the courts rather than to the political branches.127 Similarities with Zivotofsky I also suggest that the second Baker factor may not be implicated in a challenge to a possible Section 1250A violation, as the question of whether the President has exclusive constitutional authority to withdraw from treaties, including the North Atlantic Treaty, would require courts to analyze constitutional text, structure, and history—which the Zivotofsky I Court emphasized are quintessential judicial standards.128
On the other hand, the executive branch may cite Justice Rehnquist's plurality opinion in Goldwater to argue that a dismissal is appropriate on the ground that such a challenge presents a political question. According to the Goldwater plurality opinion, a treaty-withdrawal case "must surely be controlled by political standards" given "the absence of any constitutional provision governing the termination of a treaty, and the fact that different termination procedures may be appropriate for different treaties."129 The Goldwater plurality stated that this conclusion is further supported by the fact that the case "involve[d] foreign relations."130 Although Zivotofsky I arguably rendered this latter point less relevant,131 the Goldwater plurality also emphasized that the type of foreign policy issue at stake in the case was "a treaty commitment to use military force in the defense of a foreign government if attacked"132—a consideration that would also be implicated in a case involving presidential withdrawal from the North Atlantic Treaty in contravention of Section 1250A.
Although, as discussed, the majority's reasoning in Zivotofsky I may provide support for the claim that the political question doctrine does not bar judicial review of a challenge to Section 1250A, litigants may face hurdles under another justiciability doctrine that the executive branch may invoke in seeking to get a challenge to an alleged violation of Section 1250A dismissed—namely, standing.
The next justiciability doctrine that could affect whether a court resolved the merits of a Section 1250A case is standing. Like the political question doctrine, the Supreme Court developed the standing doctrine based on the Court's interpretation of the limits of the federal judiciary's authority under Article III of the U.S. Constitution to decide "cases" and "controversies."133 While the political question doctrine focuses on whether the questions presented by the case are appropriate for judicial resolution, the standing doctrine focuses on whether the plaintiff is the right litigant to bring the case.134
To establish standing, the Court has set forth three primary requirements that litigants must meet.135 These three requirements are designed to ensure that plaintiffs have a "'personal stake in the outcome' in order to 'assure that concrete adverseness which sharpens the presentation of issues necessary for the proper resolution'" of the case.136

Requirements to Establish Standing To establish standing, litigants must show

Applying the Supreme Court's standing jurisprudence, litigants challenging an alleged violation of Section 1250A would have to demonstrate that they suffered an injury of the sort required by the Supreme Court's standing doctrine as a result of a President's unilateral withdrawal from the North Atlantic Treaty. The Court requires that plaintiffs establish that they suffered or will imminently suffer a "particularized" injury—that is, one that affects [them] in a personal and individual way"138—rather than a "generalized grievance" common across the public at large.139 The Court has emphasized that it is not sufficient for plaintiffs to assert "'only the generalized interest of all citizens in constitutional governance'" or in "hav[ing] the Government act in accordance with law."140 Although an injury may sometimes be "widely shared,"141 to have standing, litigants must allege that they personally suffered or will imminently suffer an injury sufficiently "discrete" and "concrete" to be distinctive to them.142
The nature of the standing analysis in a Section 1250A case may, to some extent, depend on whether the plaintiff was a Member of Congress or a private individual.
Although cases involving congressional plaintiffs make up a relatively small portion of the Supreme Court's standing cases, the Court has developed several principles specific to congressional standing.143 In the 1997 case Raines v. Byrd, the Court clarified that it distinguishes between cases in which individual legislators have suffered an injury unique to them—such as being deprived of salary as a result of being unlawfully prevented from taking their congressional seats144—and cases in which Members of Congress allege an "institutional injury"—that is, an injury to the governance body of which they are a part, such as the voting power of a chamber or of Congress as a whole.145 As discussed, Members of Congress have brought challenges to Presidents' unilateral withdrawal from treaties in the past.146 In those cases in which courts addressed standing, they generally viewed the alleged injury—treaty termination without congressional approval—as an institutional one.147
The Supreme Court has indicated that an allegation of an institutional injury may establish standing in fewer circumstances than an allegation of a personal injury by a Member of Congress.148 Because institutional injuries are typically shared by all members of a legislative body equally, they are often more appropriately remedied through political action rather than adjudication, the Court has reasoned.149 The Court has stated, however, that where a group of legislators can establish that their votes were effectively "nullified," they may be able to establish an institutional injury sufficient for purposes of standing.150 In such circumstances, the Court has explained, the institutional injury is to the legislators' "plain, direct and adequate interest in maintaining the effectiveness of their votes."151
While the Court has seemingly indicated that the cases in which legislators will be able to establish an institutional injury for purposes of standing by showing "complete[] nullifi[cation" of their votes may be relatively rare,152 the Court has also suggested that this showing might be made more easily if the congressional plaintiffs are "authorized to represent their respective Houses of Congress"153 or Congress as a whole.154 When the body suffering the alleged injury has authorized the suit, the Court has reasoned, the institutional plaintiff may be able to establish standing by showing that the challenged action would nullify a vote by the entire legislative body.155 Accordingly, as Section 1250A prohibits the President from withdrawing from the North Atlantic Treaty without approval by two-thirds of the Senate or an act of Congress, if Congress or one of its chambers authorized suit to be brought on its behalf, a court may conclude that an injury had been alleged sufficient to establish standing because the alleged unlawful action nullified the chamber's or Congress's vote on whether the United States should withdraw from the treaty.
An early version of 1250A that passed in the Senate would have created a process to authorize suit to be brought on behalf of the Senate or House of Representatives to enforce the law's congressional approval requirements,156 but final Section 1250A language agreed to in conference did not contain this provision.157 While the Supreme Court has not expressly held that authorization is necessary, the Court's standing jurisprudence suggests that such authorization increases the likelihood of establishing congressional standing in cases, such as a challenge by a congressional plaintiff to a Section 1250A violation, that courts may view as alleging an institutional injury.
Outside the context of congressional standing, if a private plaintiff were to challenge unilateral withdrawal from the North Atlantic Treaty, legislation other than Section 1250A might affect a court's standing analysis. Numerous laws reference or relate to NATO, the North Atlantic Treaty, or subsidiary international agreements concluded under the NATO rubric,158 and these laws could be relevant to the standing analysis in a private plaintiff's case.

NATO-Related Legislation NATO-related legislation enacted in domestic law includes the following:
|
Unilateral presidential withdrawal from NATO would not automatically repeal NATO-related legislation because the Supreme Court has recognized that the repealing of statutes generally must conform to the same bicameral process used to enact new legislation.167 At the same time, private individuals or entities might argue that U.S. withdrawal interfered with NATO-related rights and opportunities reflected in statute.168 For example, withdrawal from NATO could leave uncertain the status of federal acquisition and export control authorities that simplify certain commercial transactions involving NATO countries.169 NATO withdrawal might also call into question the status and future availability of NATO visas for NATO officials, staff, and immediate family members.170 In seeking to establish standing, litigants might contend that withdrawal from the North Atlantic Treaty undermined their statutory rights or expectations of rights under a particular NATO-related statute, which led to a concrete and particularized injury.171 The Supreme Court has recognized that "[t]he actual or threatened injury required [to establish standing] may exist solely by virtue of statutes creating legal rights, the invasion of which creates standing."172
As discussed, the Supreme Court has never heard a treaty withdrawal case on its merits, and no court has addressed the constitutionality of a statute restricting the President's ability to withdraw from a treaty. The analytical approaches that the Court has taken in separation of powers cases involving other issues may inform any case involving a statute that the executive branch claims impermissibly infringes on the President's constitutional authority.
The Supreme Court has developed approaches to decide separation of powers issues in other cases that courts might draw upon in assessing any potential challenges to a President's withdrawal from a treaty in alleged violation of a statutory prohibition such as that in Section 1250A. A court's evaluation of such a challenge would likely begin with the framework that the Supreme Court has recognized as appropriate for determining the scope of presidential powers relative to those of Congress, including in cases involving foreign policy issues: Justice Robert Jackson's concurrence in Youngstown Sheet & Tube Co. v. Sawyer.173 Under the Youngstown framework, courts assess presidential claims of authority based on what Congress has—or has not—said about the matter. As Justice Jackson observed: "Presidential powers are not fixed but fluctuate, depending upon their disjunction or conjunction with those of Congress."174 Justice Jackson accordingly formulated a tripartite framework for analyzing the scope of presidential power.
|
The Tripartite Framework in Justice Jackson's Youngstown Concurrence Presidential Maximum. Where Congress has expressly or implicitly authorized the President's action, presidential power is at its "maximum" and "supported by the strongest of presumptions and the widest latitude of judicial interpretation."175 Zone of Twilight. Cases in which Congress has neither authorized nor prohibited executive branch action lie in an inscrutable "zone of twilight in which [the President] and Congress may have concurrent authority, or in which its distribution is uncertain," and "any actual test of power is likely to depend on the imperatives of events and contemporary imponderables rather than on abstract theories of law."176 Lowest Ebb. Where Congress has expressly or impliedly prohibited executive action, presidential power "is at its lowest ebb," as it is an assertion of executive authority "at once so conclusive and preclusive [that it] must be scrutinized with caution, for what is at stake is the equilibrium established by our constitutional system."177 |
In the 1981 case Dames & Moore v. Regan,178 the Supreme Court elaborated on the Youngstown framework by observing that "it is doubtless the case that executive action in any particular instance falls, not neatly in one of three pigeonholes, but rather at some point along a spectrum running from explicit congressional authorization to explicit congressional prohibition."179 Additionally, in analyzing where the constitutional lines between the legislative and executive branches lie, the Court often "put[s] significant weight upon historical practice,"180 which the Court has stated may "be treated as a gloss" on the Constitution's provisions.181 The Youngstown framework's focus on congressional actions coupled with the constitutional significance that the Court often accords to historical practice of the political branches means that the Court's analysis of the distribution of powers to a considerable extent depends on the ways in which it interprets any relevant statutes and the interactions of Congress and the President over time.182
The Supreme Court has applied the Youngstown framework in other opinions that a court might find relevant in evaluating a presidential claim of power to withdraw from the North Atlantic Treaty in violation of Section 1250A, including the two discussed in the following sections.
In a significant 2015 foreign policy case—Zivotofsky ex rel. Zivotofsky v. Kerry (Zivotofsky II)183—a majority of the Supreme Court applied the Youngstown framework to uphold, for what appears to be the first time, a presidential action that the Court determined fell into category three.184 In this case, the Court held that the President has an "exclusive" and "conclusive" power185 that "disabl[es] the Congress from acting upon the subject"—specifically, the recognition of foreign states.186 As the Court explained, "[r]ecognition is a 'formal acknowledgement' that a particular 'entity possesses the qualifications for statehood' or 'that a particular regime is the effective government of a state.'"187
As discussed, the Court earlier held in Zivotofsky I that the case was justiciable because no political question was presented by the plaintiff's challenge to the State Department's refusal to comply with the statute requiring the State Department to record in a passport or a consular report of birth abroad the birthplace of U.S. citizens born in Jerusalem as "Israel."188 On remand, the D.C. Circuit held that the statute was unconstitutional.189 After holding that the President had exclusive power to recognize foreign states,190 the court determined that the statutory requirement impermissibly infringed on that power because it "force[d] the State Department to deviate from its decades-long position of neutrality on what nation or government, if any, is sovereign over Jerusalem."191
The Supreme Court granted review for a second time in the litigation192 and upheld the D.C. Circuit's decision.193 The Court began its analysis by observing that "[i]n considering claims of Presidential power this Court refers to Justice Jackson's familiar tripartite framework from Youngstown."194 Because the President's action at issue—"refusal to implement" the passport statute—"falls into Justice Jackson's third category," the Court stated, the President's claim of authority "must be 'scrutinized with caution,' and he may rely solely on powers the Constitution grants to him alone."195 Acknowledging that the text of the Constitution does not expressly reference the recognition power,196 the Court nevertheless concluded that the Constitution implicitly grants the President such power based on the President's other express Article II powers and the Constitution's structure.197
According to the Court, the inference of a presidential power of recognition is supported by the President's Article II powers to "receive Ambassadors and other public Ministers,"198 to "make Treaties, provided two thirds of the Senators present concur,"199 and to "nominate, and by and with the Advice and Consent of the Senate, [to] appoint Ambassadors" and "other public Ministers and Consuls."200 As a matter of constitutional structure, the Court reasoned, the President has the sole power to receive ambassadors and other public ministers and to "negotiate treaties," while "Congress . . . has no constitutional power that would enable it to initiate diplomatic relations with a foreign nation."201 The Court thus concluded that the Constitution's "text and structure grant the President the power to recognize foreign nations and governments"; however, the Court also observed these textual and structural factors did not alone answer the question of "whether that power is exclusive."202
In addressing exclusivity, the Court looked to functional considerations (e.g., the necessity that the United States "speak with one voice"),203 judicial precedent,204 and the historical practice of the political branches.205 These methods of constitutional interpretation led the Court to hold that the President not only has the power of recognition, but that that power resides solely in the presidency.206 Further, because the Court determined that the passport statute required the Secretary of State to "directly contradict[]" the President's recognition decision,207 the Court held that the statute must be struck down because Congress had thereby "improper[ly]" "aggrandiz[ed] its power at the expense of another branch."208
Emphasizing that its decision did "not question the substantial powers of Congress over foreign affairs in general or passports in particular,"209 the Court suggested that its holding was a narrow one that left ample room for Congress to "express its disagreement with the President['s] recognition decision in myriad ways," such as by "enact[ing] an embargo, declin[ing] to confirm an ambassador, or even declar[ing] war."210 The Court further emphasized that its exclusivity analysis was confined to the President's recognition power and did not subsume the executive branch's broader claim that that power derives from the President's "exclusive authority to conduct diplomatic relations" and possession of the "bulk of foreign-affairs powers."211
The Supreme Court's decision concerning presidential immunity from criminal prosecution in Trump v. United States might also be relevant in a separation of powers case concerning Section 1250A. The Supreme Court in Trump relied on Youngstown to provide an extensive discussion of exclusive and preclusive presidential powers.212 The Court explained that separation of powers principles prohibit legislation—criminal or otherwise—that restricts Presidents' exercise of their "conclusive and exclusive powers"213 (which the Court also referred to as the President's "core constitutional powers"214). These conclusive and exclusive powers, the Trump Court held, include some actions not specifically mentioned in the Constitution's text, such as removing executive officers whom the same President appointed, recognizing foreign states,215 and discussing potential investigations and prosecutions with the Department of Justice.216
The following section analyzes how a court might apply the foregoing Supreme Court precedent to a presidential claim of exclusive power to withdraw from the North Atlantic Treaty in contravention of Section 1250A.
A court might frame its analysis in a case challenging a President's violation of Section 1250A using the Youngstown framework, as the Supreme Court framed its analysis of the separation of powers issue in Zivotofsky II. Under that framework, if a court determines that the presidential action contravenes an express congressional prohibition and falls into category three, the action may be upheld only if the court determines that the Constitution grants the President exclusive power such that Congress is prohibited "from taking action upon the subject."217 The Supreme Court has emphasized that presidential action contrary to the expressed will of Congress must be "scrutinized with caution," as it is in such situations that the President's power is at its "lowest ebb."218 In assessing a President's claim of exclusive authority to withdraw from treaties under that seemingly heightened level of scrutiny, a court would likely consider constitutional text and structure, relevant judicial precedent, and the historical practice of the political branches.
As the Constitution is silent with respect to the treaty withdrawal power, both parties to a case challenging a Section 1250A violation would likely cite other constitutional provisions as well as constitutional structure in support of their positions on treaty withdrawal authority. Those challenging a violation might emphasize that, although the Constitution does not explicitly reference treaty withdrawal, it does specify a process for the branches to exercise shared powers to enter into treaties: The President "make[s]" treaties, but the United States may become a party to a treaty219 only if the Senate provides its advice and consent and two-thirds of the Senators concur. 220 Given that treaty entry and withdrawal both affect the content of U.S. international legal obligations as well as of federal law that may trump U.S. state laws under the Supremacy Clause,221 one might reason that the distribution of entry and withdrawal powers should be symmetrical and subject to the same checks and balances.
Challengers might further contrast treaty withdrawal with the recognition power, which appears to be the only foreign policy authority to date that the Supreme Court has found to be exclusive and beyond congressional regulation.222 In contrast to U.S. participation in treaties, the Constitution does not speak directly to U.S. recognition of foreign states. Some could argue that this difference suggests that the Supreme Court's reasoning in Zivotofsky II for acknowledging the President's exclusive recognition power does not apply to the treaty withdrawal context. Given that claims of exclusive presidential authority must be "scrutinized with caution,"223 it might be contended that the existence of a congressional role in treaty entry weighs against an interpretation of the Constitution that excludes Congress from participation in treaty withdrawal.
The executive branch, for its part, might contend that the Constitution's silence on treaty withdrawal is not determinative because the Supreme Court has been willing to recognize other exclusive presidential powers that are not expressly granted in the Constitution.224 These exclusive presidential powers include not only the recognition power, but also the power to remove executive officers whose appointment, like treaty entry, requires Senate approval.225 The executive branch might further argue, as it has in the past in support of the President's unilateral authority in foreign affairs, that the President has inherent Article II power based on the "combined force" of several Article II provisions,226 including the vesting of "[t]he executive power" in the President,227 the Take Care Clause,228 the Commander in Chief Clause,229 the Reception Clause,230 and the Treaty Clause.231 The OLC invoked that line of reasoning in its 2020 opinion in support of its argument that the President has exclusive authority to withdraw from treaties: "Taken together, these provisions [of Article II] grant the President the authority and discretion to implement a treaty by notifying foreign powers of the United States' exercise of its right to withdraw from the treaty."232
As discussed, there is no directly controlling precedent regarding the distribution of treaty-withdrawal authority.233 Both sides to a case regarding a Section 1250A violation may emphasize aspects of potentially relevant cases that could support their respective position and distinguish those aspects that might be understood as unfavorable to them.
Those challenging a Section 1250A violation might highlight the Supreme Court's broad statements about foreign affairs authorities, which arguably support the idea that most foreign powers are shared because the Constitution assigns those authorities to the national government as a whole.234 Challengers also might emphasize that many Supreme Court precedents that could be understood as characterizing presidential foreign affairs powers as broad did not involve questions of exclusive authority, but rather questions of whether the President could act in the absence of express congressional authorization.235 Additionally, challengers might maintain that if, as the executive branch maintains, treaty withdrawal is an instance of executing treaties as the "law of the land,"236 Section 1250A must also be understood as the law of the land pursuant to Congress's treaty-implementing power, which has long been recognized by the Supreme Court.237
Challengers may also point out that, even when the Supreme Court determined that the President has exclusive authority to recognize foreign states in Zivotofsky II, the Court emphasized the narrowness of this power238 and cautioned that "it is essential the congressional role in foreign affairs be understood and respected."239 In addition, challengers might emphasize that the Zivotofsky II Court dismissed as dicta earlier, expansive language about presidential foreign policy power in United States v. Curtiss-Wright Export Corp.,240 a New Deal-era case that the executive branch relied on in support of broad claims of exclusive authority "to conduct diplomatic relations" and "the bulk of foreign affairs powers."241 "[D]eclin[ing] to acknowledge this unbounded power," the Court explained that "[t]he Executive is not free from the ordinary controls and checks of Congress merely because foreign affairs are at issue."242
The executive branch might respond by contending that the functional considerations recognized by the Supreme Court—such as the institutional capacity of the President to speak with "one voice" on behalf of the nation in international affairs243—have particular salience in the context of treaty withdrawal. In its 2020 opinion claiming that the President has exclusive treaty-withdrawal authority, the OLC cited the Court's reasoning in Zivotofsky II based on such functional considerations in arguing that the case "reinforces the [OLC's] conclusion that the President's authority to exercise the United States' right to withdraw from a treaty is exclusive."244 According to the OLC, "[n]o less than the power to recognize foreign sovereigns, the decision to withdraw from a treaty 'is a topic on which the Nation must speak with one voice.'"245
The executive branch might also argue that Congress's authority to implement treaties does not include restricting the President's authority to withdraw from them. In its 2020 opinion, the OLC argued that the statutory notification and waiting period restrictions on the President's withdrawal from the Open Skies Treaty are "not an exercise of Congress's authority to adopt laws to implement treaties as part of our domestic law."246 According to the OLC, "[t]he power of Congress to implement a treaty does not itself imply a power to direct the President to engage in diplomacy or control the manner by which the President executes the rights of the United States under treaties."247
Given the arguably inconclusive nature of constitutional text, structure, and jurisprudence regarding treaty-withdrawal authority—and particularly whether any of that authority is exclusive—courts might look to historical practice for "gloss" on constitutional meaning as they have done in other separation of powers cases.248 The parties accordingly would likely also advance arguments based on historical practice in support of their positions.
Those challenging a Section 1250A violation might maintain that the pre-20th century practice of regular congressional involvement in treaty withdrawal discussed above249 demonstrates that the President and Congress adopted the constitutional interpretation that treaty withdrawal is, like treaty entry, a shared power. In light of that past practice, they might further argue that the more recent trend of unilateral presidential withdrawal at most demonstrates that Congress may at times have accepted the President has independent authority—that is, in the absence of congressional restriction—to withdraw from treaties, but not an acceptance that the power is exclusive.250 After all, challengers might point out, it does not appear that the executive branch took the position that the treaty-withdrawal power was exclusive to the President until 2020, and Congress responded with the enactment of Section 1250A soon after the executive branch announced that view.
Additionally, challengers might argue that the relevant historical practice extends to other types of congressional actions affecting U.S. participation in treaties, such as treaty-implementing legislation and notification and reporting requirements.251 Looking to a broader set of practices, one might argue that statutes such as the law requiring that the President provide Congress with a notice period before withdrawing from the Open Skies Treaty252 evince a congressional understanding that treaty-withdrawal authority is shared. Other potentially relevant examples include statutory restrictions on the President's ability to unilaterally modify treaties253 or to alter U.S. international legal obligations unless through a Senate-approved treaty.254
The executive branch, by contrast, might maintain that Zivotofsky II calls for a more focused set of historical examples, and that the relevant practice is limited to assertions of authority that relate to treaty withdrawal directly. The executive branch might argue that the Supreme Court's approach in Zivotofsky II to interpreting past practice sets a high bar for Congress to evince an understanding that a given power is not exclusive to the presidency. Although the Court cited historical instances in which the President consulted with Congress about recognition decisions and Congress enacted appropriations and other legislation related to those decisions, the Zivotofsky II Court did not interpret those examples as indicating an understanding that recognition is a shared power.255 Instead, the Court found that the examples demonstrated "no more than that some Presidents have chosen to cooperate with Congress, not that Congress itself has exercised the recognition power."256 The Court arguably suggested that only congressional action directly contrary to the President's exercise of a power will suffice as historical evidence of congressional assertion of that power. As the Court observed: "'[T]he most striking thing' about the history of recognition is what 'is absent from it: a situation like this one,' where Congress has enacted a statute contrary to the President's formal and considered statement concerning recognition."257
Furthermore, the executive branch might contend that the Zivotofsky II Court's approach to the political branches' historical practices was heavily informed by functional considerations—most prominently the ability of the President to "speak . . . with one voice" on behalf of the nation in the international arena.258 According to the Court, the President is "better positioned to take the decisive, unequivocal action necessary to recognize other states at international law,"259 which Congress "on balance has acknowledged the importance of."260 The executive branch might argue that the same clarity and decisiveness is necessary in the United States' treaty relations, and therefore functional considerations favor unliteral presidential decisionmaking over treaty withdrawal.
In sum, existing Supreme Court precedent may not provide a clear answer on the question that would be presented by a President's claim of exclusive authority to withdraw from the North Atlantic Treaty in contravention of Section 1250A. Rather, if a court agreed to hear a case on the merits, both sides would likely present arguments based on constitutional text and structure, relevant judicial precedent, and historical practice of the political branches in support of their respective positions.
As the foregoing discussion makes clear, the question of whether the President possesses authority to withdraw from the North Atlantic Treaty without congressional or senatorial approval implicates a long-standing and still-unresolved debate over the Constitution's allocation of the power to withdraw from treaties. If a court were to conclude that Section 1250A places a President's unilateral withdrawal from the North Atlantic Treaty in Youngstown's category three, to defend such a violation, the executive branch would have to establish that the President has exclusive authority to withdraw from treaties,261 an argument that the executive branch advanced in a 2020 OLC opinion.262 The Supreme Court was willing to find exclusive presidential powers in both Zivotofsky II and Trump,263 but it remains uncertain how a court would rule if it were to agree to hear a case challenging a Section 1250A violation given the absence of controlling Supreme Court precedent on the treaty-withdrawal power.264
Absent judicial enforcement, Congress may consider responding to what it believes to be a violation of Section 1250A by using its institutional tools to influence the executive branch, which include impeachment, oversight, exercising the power of the purse to eliminate executive branch funding, and withholding approval for nominations.265
Additionally, if a President were to withdraw the United States from the North Atlantic Treaty, all existing NATO-related legislation would appear to remain in effect, and it would be up to Congress to determine whether any statutes should be repealed or amended. Because many NATO-related provisions are not dependent on whether the United States is a party to the treaty,266 Congress may be able to achieve some NATO-related policy objectives through new legislation. For example, in response to President Carter's withdrawal from the United States' mutual defense agreement with Taiwan in 1979,267 Congress enacted the Taiwan Relations Act,268 which provides that "the United States will make available to Taiwan such defense articles and defense services in such quantity as may be necessary to enable Taiwan to maintain a sufficient self-defense capability."269
Congress may also consider that, in addition to statutory prohibitions of unilateral presidential treaty withdrawal such as in Section 1250A, other congressional actions that might be understood by courts or the political branches as assertions of congressional treaty withdrawal authority include, for example, placing restrictions on the President's authority to withdraw from treaties in the Senate's resolutions providing advice and consent to the President's ratification of those treaties270 or in authorizing legislation.271
Congress may also consider the potentially complex state of affairs if a court were to enforce Section 1250A and enjoin a President from unilaterally withdrawing from the North Atlantic Treaty. Even with an injunction in place, other questions may arise over whether the President could be compelled to honor the United States' treaty commitments, such as the mutual defense obligations under Article 5 of the North Atlantic Treaty.272 Initially, any attempt to mount a judicial challenge to an alleged failure to meet U.S. NATO obligations would likely face justiciability hurdles such as the political question and standing doctrines discussed above.273 Additionally, the executive branch might maintain that any judicial action could not interfere with the President's "exclusive sphere of constitutional authority,"274 which the executive branch might claim includes presidential powers like the Commander-in-Chief authority.275
Finally, regardless of the outcome of any case in which a court may agree to hear a challenge to a Section 1250A violation, there may remain ways the legislative and executive branches could affect the United States' policy regarding NATO through the use of their respective constitutional authorities. Such authorities may include Congress's powers related to foreign commerce, use of the armed forces, and spending, and the President's powers as Commander in Chief and to receive ambassadors and other foreign government officials.276
Congress may find it useful to consider the legal contexts outlined in this report and the issues that could arise as it continues to exercise its legislative and oversight powers with regard to the North Atlantic Treaty, as well as other treaties to which the United States is a party.

22 U.S.C. § 1928f(a). While a suspension generally refers to a temporary pause in compliance with a treaty, withdrawal, termination, and denunciation all refer to a permanent exit from the treaty. See, e.g., Restatement (Fourth) of Foreign Relations Law of the United States § 313 (Am. L. Inst. 2018). Furthermore, a withdrawal occurs in the context of a multilateral agreement in which one party may withdraw from the agreement, but the agreement remains in place. A termination occurs in the context of a bilateral agreement in which the withdrawal of a single party effectively terminates the agreement. See Restatement (Second) of Foreign Relations Law of the United States § 155 cmt. c (Am. L. Inst. 1965). Lastly, denunciation is largely synonymous with termination, but frequently follows an accusation that the treaty was breached. See, e.g., Herbert W.

The court further explained that "we have no occasion to decide whether [the existence of a termination clause] would be determinative in a case lacking other factors identified above, e.g., under a notice of withdrawal from the NATO treaty unaccompanied by derecognition of the other signatories." Id. at 708.

Id. at 1007 (Brennan, J., dissenting). He further argued that the President's unilateral withdrawal should be upheld because it "was a necessary incident to" the President's exercise of the power of recognition of foreign states, which, Brennan explained, "the Constitution commits to the President alone."

Although the Zivotofsky I majority discussed only the first two factors, it did not state that courts should no longer consider the others. Additionally, Justice Sotomayor wrote a concurring opinion suggesting that the majority should have engaged in a more thorough analysis and discussing the relevance of all six Baker factors See Zivotofsky I, 566 U.S. at 203‒07 (Sotomayor, J., concurring). She also wrote to emphasize that, while she agreed with the majority's conclusion that Zivotofsky's case did not present a political question, she did not believe the majority's opinion should be read as holding that no case involving an issue of a statute's constitutionality or requiring a court to resort to text, history, and structure for its resolution could present a political question.

The Court's Zivotofsky I decision sparked debate among commentators about whether it portended a greater willingness on the part of the Court to decide foreign policy cases. Compare, e.g., Ganesh Sitaraman & Ingrid Wuerth, The Normalization of Foreign Relations Law, 128 Harv. L. Rev. 1897, 1925−27 (2015) (arguing that Zivotofsky I "is of far-reaching significance" because it "reduced the justiciability barriers to hearing [foreign affairs] cases and in doing so . . . rejected arguments that foreign relations cases need exceptional treatment"), with Curtis A. Bradley, Foreign Relations Law and the Purported Shift Away from Exceptionalism, 128 Harv. L. Rev. 294, 301 (2015) ("Zivotofsky . . . presented a relatively unusual situation in which the executive branch was asserting authority to disregard a clear statutory provision, something not presented in earlier, "exceptionalist" foreign relations law decisions in which the Court had invoked justiciability limitations, such as Goldwater v. Carter."). |

In the 1997 case Raines v. Byrd, the Court stated that the "one case" in which it found vote nullification sufficient to establish standing—which was decided in 1939—"stands (at most . . .) for the proposition that legislators whose votes would have been sufficient to defeat (or enact) a specific legislative Act have standing to sue if that legislative action goes into effect (or does not go into effect), on the ground that their votes have been completely nullified." Id. at 821‒24 (citing Coleman, 307 U.S. at 438, 431, & 446) (emphasis added).

In Youngstown, the Supreme Court struck down President Truman's order seizing many of the nation's steel mills—which he justified based on the need to ensure the availability of sufficient materiel for fighting the Korean War—on the ground that the President did not have either congressional or constitutional authority to take such action. See Youngstown, 343 U.S. at 585–89; see also id. at 640 (Jackson, J., concurring) ("[T]he current seizure [can] be justified only by the severe tests under the third grouping, where it can be supported only by any remainder of executive power after subtraction of such powers as Congress may have over the subject."). |

See id. at 14–15 ("Put simply, the Nation must have a single policy regarding which governments are legitimate in the eyes of the United States and which are not.

These assurances cannot be equivocal."). |
| 204. |
See id. at 14–15. The Court explained that "[n]o single precedent resolves the question whether the President has exclusive recognition authority": In part that is because, until today, the political branches have resolved their disputes over questions of recognition. The relevant cases, though providing important instruction, address the division of recognition power between the Federal Government and the States—not between the President and Congress. Id. at 17. Although no case had directly addressed whether the recognition power was exclusive to the Presidency, the Court concluded that several cases in which the Court discussed the recognition power "illustrate [that] the Court has long considered recognition to be the exclusive prerogative of the Executive." Id. at 19. |

Id. at 70 (Scalia, J., dissenting). |

The Court determined without much elaboration that the decision not to recognize any state's sovereignty over Jerusalem is part of the President's exclusive recognition power and that the State Department's recording of a U.S. citizen born in Jerusalem as "Israel" would contradict that decision. See id. at 5 (stating that the Court had two questions before it: "whether the President has the exclusive power to grant formal recognition to a foreign sovereign," and, "if he has that power, . . . whether Congress can command the President and his Secretary of State to issue a formal statement that contradicts the earlier recognition"). Chief Justice Roberts and Justices Alito and Scalia disagreed with those conclusions. See id. at 64, 66 (Roberts, C.J., dissenting) ("[T]he statute at issue does not implicate recognition . . . . Whatever recognition power the President may have, exclusive or otherwise, is not implicated by [the passport statute]."); id. at 76–77 (Scalia, J., dissenting) (criticizing the majority for "conclud[ing] that, in addition to the exclusive power to make the 'formal recognition determination,' the President holds an ancillary exclusive power 'to control . . . formal statements by the Executive Branch acknowledging the legitimacy of a state or government and its territorial bounds'" (quoting id. at 31)). |

Additionally, in holding that the President has independent authority inherent in Article II to settle foreign claims in the absence of explicit congressional authorization, the Court in Dames & Moore v. Regan, 453 U.S. 654 (1981), emphasized "the narrowness" of [its] decision," highlighting that it had determined that historical practice indicated that Congress had "acquiesced" in such authority.

In concluding that President Carter's unilateral withdrawal from the United States' mutual defense treaty with Taiwan was constitutional in the Goldwater case, the D.C.

Cir. 1979) (en banc) (per curiam), vacated and remanded with instructions to dismiss, Goldwater v. Carter, 444 U.S. 996 (1979) (plurality opinion) ("The question of whether the Senate may be able to reserve to itself in particular treaties, at the time of their original submission, a specific role in their termination is not presented by the record in this appeal and we decide nothing with respect to it."). |

Although the Supreme Court has referenced the President's role as Commander in Chief in discussing foreign affairs authorities generally, the Court generally has not specified the contours of that authority. See, e.g., Chicago & S. Air Lines v. Waterman S. S. Corp., 333 U.S. 103, 109 (1948) ("The President also possesses in his own right certain powers conferred by the Constitution on him as Commander-in-Chief and as the Nation's organ in foreign affairs."). In a 19th century case, Chief Justice Salmon Chase posited in a concurring opinion joined by three other Justices that the President has some independent—and possibly exclusive—power to direct military campaigns: Congress has the power not only to raise and support and govern armies but to declare war. It has, therefore, the power to provide by law for carrying on war. This power necessarily extends to all legislation essential to the prosecution of war with vigor and success, except such as interferes with the command of the forces and the conduct of campaigns. That power and duty belong to the President as commander-in-chief. Ex parte Milligan, 71 U.S. (4 Wall.) 2, 139 (1867) (Chase, C.J., concurring) (emphasis added). |
| 276. |
Cf Zivotofsky ex rel. Zivotofsky v. Kerry, 576 U.S. 1, 16 (2015) ("Although the President alone effects the formal act of recognition, Congress' powers, and its central role in making laws, give it substantial authority regarding many of the policy determinations that precede and follow the act of recognition itself. If Congress disagrees with the President's recognition policy, there may be consequences. Formal recognition may seem a hollow act if it is not accompanied by the dispatch of an ambassador, the easing of trade restrictions, and the conclusion of treaties. And those decisions require action by the Senate or the whole Congress."). |
