Congressional Participation in Litigation:

Article III and Legislative Standing 
Wilson C. Freeman 
Houses, committees, and Members of Congress periodically seek to initiate or participate in 
Legislative Attorney 
litigation to, among other purposes, advance their legislative objectives, argue that the Executive 
  
is violating their legislative prerogatives, or defend core institutional interests. However, the 
Kevin M. Lewis 
constitutionally based doctrine of “standing”—which requires a litigant seeking federal judicial 
Legislative Attorney 
relief to demonstrate (1) a concrete and particularized and actual or imminent injury-in-fact 
  
(2) that is traceable to the allegedly unlawful actions of the opposing party and (3) that is 
redressable by a favorable judicial decision—may prevent legislators from pursuing litigation in 
 
federal court. The U.S. Supreme Court and the lower federal courts have issued several important 
opinions analyzing whether—and under what circumstances—a legislative entity has standing to seek relief.  
Although legislative standing jurisprudence defies easy characterization, it is possible to distill several principles from 
existing precedent. For example, whereas courts commonly allow individual legislators to assert injuries to their own 
personal interests, following the Supreme Court’s seminal opinion in Raines v. Byrd, 521 U.S. 811 (1997), courts have 
generally (though not universally) been less willing to permit individual legislators to seek redress for injuries to a house of 
Congress as a whole, at least in the absence of explicit authorization to do so from the legislative body itself. The Supreme 
Court’s case Coleman v. Miller, 307 U.S. 433 (1939), is generally understood as setting forth the lone exception, allowing 
individual legislators to sue when their vote has been “nullified” by some claimed illegal action. In addition, generally 
speaking, a congressional plaintiff cannot predicate a federal lawsuit solely on a complaint that the executive branch is 
misapplying or misinterpreting a statute, as litigants must demonstrate concrete and particularized injury to themselves.  
In addition to initiating litigation, Congress also occasionally seeks to intervene in preexisting litigation. In cases in which the 
executive branch has declined to defend a federal statute from a constitutional challenge, for example, congressional entities 
have attempted to intervene as defendants in support of the law. The Supreme Court, in INS v. Chadha, 462 U.S. 919 (1983) 
and United States v. Windsor, 570 U.S. 744 (2013), has allowed Congress to intervene to defend a law that the executive 
branch has declined to defend but still enforces. Nonetheless, neither case resolved whether significant exceptions to this rule 
exist, let alone explored what rules are in place when the President both declines to defend and enforce a federal law. 
Moreover, in cases that do not involve the executive branch’s refusal to defend a federal statute, Congress’s ability to 
intervene as a full party to the case may be more circumscribed. 
Even when Congress lacks standing to initiate or intervene in a federal lawsuit as a full-fledged party, Congress may still play 
a role in litigation by participating as an amicus curiae, or “friend of the court.” Courts frequently allow Members, houses, 
and committees of Congress to file amicus briefs in support of (or opposition to) particular parties or positions.

Introduction 
Since the founding, the federal courts have played a critical role in adjudicating legal disputes, 
including ones involving executive action. As the Supreme Court stated in Marbury v. Madison, 
“where a specific duty is assigned by law . . . the individual who considers himself injured[] has a 
right to resort to the laws of his country for a remedy.”1 Naturally, Congress and its Members 
have an interest in litigating in federal court, for example, to vindicate their institutional 
priorities,2 to argue that the Executive is violating their legislative prerogatives, or to advance 
their legislative policy interests. During the Obama Administration, for instance, legislative 
entities brought or joined litigation in federal court for a host of reasons, such as to challenge the 
Executive’s decision to allegedly expend money without a congressional appropriation,3 to 
defend the Defense of Marriage Act from constitutional challenge in lieu of the Executive,4 and to 
challenge the Executive’s decision to engage in military action in Libya.5 Likewise, during the 
Trump Administration, legislators have become involved in lawsuits that challenge the 
President’s alleged unconstitutional acceptance of emoluments,6 suits demanding the production 
of documents from the Administration,7 and, in an amicus capacity, challenges to legality of the 
so-called travel ban.8 Congressional interest in litigation may increase in salience under the 
current divided government, as illustrated by the House of Representatives’ resolution to 
authorize the House to participate in ongoing litigation in Texas involving the Affordable Care 
Act9 and a recent lawsuit brought by several Members of Congress challenging the President’s 
appointment of an acting attorney general.10  
However, whenever any party seeks to invoke the power of the federal courts, it must first show 
that its dispute belongs there. For nearly its entire history, the Supreme Court has emphasized that 
the role of courts is in “decid[ing] on the rights of individuals.”11 By contrast, “[v]indicating the 
public interest (including the public interest in Government observance of the Constitution and 
laws) is the function of Congress and the Chief Executive.”12 The federal courts apply a number 
of doctrines, known as justiciability doctrines, to ensure that they do not step beyond their bounds 
and decide issues more properly reserved for the other branches.13 Foremost among these

2 Congress does not always have to directly participate in the litigation for it to affect Congress’s institutional priorities. 
For example, in a lawsuit over the extent of the President’s authority under the Recess Appointments Clause, the 
plaintiff was private Pepsi-Cola distributor, even though dispute directly implicated authority of President in relation to 
the authority of the Senate. See, e.g., NLRB v. Noel Canning, 134 S. Ct. 2550, 2557 (2014).

doctrines is the requirement that a party seeking judicial relief from a federal court demonstrate 
“standing.” 
This report provides an overview of the standing doctrine as it applies to lawsuits involving 
legislators, committees, and houses of Congress. First, the report lays out the general rules of 
standing as they apply in every case in the federal courts and the main purpose behind the 
doctrine. One central purpose of the standing doctrine—protecting the court’s role in the 
constitutional balance of powers—is a theme that underlies this report, as many of these cases 
involve courts deciding whether they have the power to adjudicate high-profile political disputes 
between the other two branches of the federal government. Next, the report considers the 
relatively few Supreme Court cases to discuss legislator standing, explaining the general 
principles that courts have drawn from those cases. The report then analyzes how lower courts 
have interpreted the limited Supreme Court case law on the issue, beginning with cases involving 
individual legislators, and following with cases brought by entire institutions, such as committees 
or houses of a legislature. The report then considers other issues relating to legislator participation 
in litigation, such as intervention under the Federal Rules of Civil Procedure or participation 
purely as an “amicus curiae,” or a “friend of the court.” The report concludes by identifying 
unresolved doctrinal questions and offering takeaways for prospective congressional litigants. 
Legal Background of Article III Standing 
Article III of the Constitution limits the exercise of the federal courts’ judicial power to “cases” 
and “controversies.”14 The Supreme Court has interpreted this “case or controversy” language to 
impose various restrictions on the “justiciability” of disputes in the federal courts—that is, 
constraints on the federal courts’ power to adjudicate and resolve disagreements between 
parties.15 One aspect of justiciability requires a party seeking judicial relief from a federal court to 
have “standing,” such that the party has “a personal stake in the outcome of the controversy as to 
warrant [the] invocation of federal-court jurisdiction and to justify exercise of the court’s 
remedial powers on his behalf.”16 Further, a litigant must demonstrate standing for each claim he 
seeks to press and each form of relief that he seeks to obtain.17 
The Supreme Court articulated a three-part test for standing in its seminal 1992 decision Lujan v. 
Defenders of Wildlife.18 To establish standing under that test, a party must show that it has a 
genuine stake in the relief sought because it has personally suffered (or will suffer) (1) a concrete 
                                                 
14 U.S. CONST. art. III, § 2 (“The judicial Power shall extend to all Cases, in Law and Equity, arising under this 
Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority;—to all 
Cases affecting Ambassadors, other public Ministers and Consuls;—to all Cases of admiralty and maritime 
Jurisdiction;—to Controversies to which the United States shall be a Party;—to Controversies between two or more 
States;—between a State and Citizens of another State;--between Citizens of different States;—between Citizens of the 
same State claiming Lands under Grants of different States, and between a State, or the Citizens thereof, and foreign 
States, Citizens or Subjects.”). See also Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 102 (1998) (“Article III,  
§ 2, of the Constitution extends the ‘judicial Power’ of the United States only to ‘Cases’ and “Controversies.’ We have 
always taken this to mean cases and controversies of the sort traditionally amenable to and resolved by the judicial 
process.”).

questions, and administrative questions.”)

and particularized and actual or imminent injury-in-fact (2) that is traceable to the allegedly 
unlawful actions of the opposing party and (3) that is redressable by a favorable judicial 
decision.19 While each of these requirements is complex and can blend into each other, courts 
generally regard the injury-in-fact requirement to be the “central focus” of the inquiry.20  
A party that seeks to demonstrate standing must show that his injury is “concrete”—meaning an 
injury that is “real” and not “abstract.”21 Nonetheless, an injury can be intangible in nature, as the 
deprivation of a constitutional right, like freedom of speech or the free exercise of one’s religion, 
constitutes an injury-in-fact absent any tangible economic loss.22 While it may sometimes be 
difficult to draw a distinction between an “intangible” injury and an “abstract” injury,23 the Court 
has provided some guidance. For example, the Court has held that an alleged injury sufficient for 
standing may be one similar to those that have “traditionally been regarded as providing a basis 
for a lawsuit in English or American courts,” such as the interest of a qui tam relator in the 
outcome of his suit.24 The Court has also stated that Congress can build on common law 
conceptions of injury, as Congress is “well positioned” to “identify intangible harms that meet 
minimum Article III requirements” and establish new causes of action to remedy such harms.25 
Finally, the Court has explicitly considered and rejected several types of abstract injuries in 
previous cases. For instance, in Valley Forge Christian College v. Americans United for 
Separation of Church and State, the Supreme Court held that a public interest organization lacked 
standing to challenge the transfer of federal land to a religiously affiliated school, as the only 
injuries identified by the plaintiffs were the “psychological consequence[s] presumably produced

20 WRIGHT & MILLER, supra note 15, § 3531.4 (“Even as the concepts blend together, however, the central focus is fixed 
on the injury requirement. The very notion of injury implies a causal connection to the challenged activity; an injury 
caused by other events is irrelevant to any purpose of standing doctrine. Causation in turn bears on remedial benefit, 
since a remedy addressed to actions that have not caused the injury will not alleviate the injury. It remains useful 
nonetheless to separate the three elements, both for purposes of exposition and for purposes of decision.”). 
21 See Spokeo, Inc. v. Robins, 136 S. Ct. 1540, 1548-49 (2016). 
22 See id. at 1549 (citing cases involving free speech and free exercise injuries). The Court has identified in many cases 
the sort of “intangible” harm that qualifies as justiciable injury. See, e.g., Dep’t of Commerce v. U.S. House of 
Representatives, 525 U.S. 316, 331-32 (1999) (stating that a plaintiff’s “expected loss of a Representative to the United 
States Congress undoubtedly satisfies the injury-in-fact requirement of Article III standing” and that “voters have 
standing to challenge an apportionment statute because they are asserting a plain, direct and adequate interest in 
maintaining the effectiveness of their votes.”); Lujan, 504 U.S. at 562-63 (“Of course, the desire to use or observe an 
animal species, even for purely aesthetic purposes, is undeniably a cognizable interest for purposes of standing.”); 
Allen v. Wright, 468 U.S. 737, 755 (1984) (“There can be no doubt that [stigmatization as a result of racial 
discrimination] is one of the most serious consequences of discriminatory government action and is sufficient in some 
circumstances to support standing.”). 
23 WRIGHT & MILLER, supra note 15, § 3531.4 (“One common practice is to distinguish between the mere ‘abstract 
injury’ that is not sufficient to confer standing and the ‘concrete injury’ that is sufficient. Application of this distinction 
or parallel phrases cannot be explained in the terms of effective advocacy. Standing is regularly recognized for litigants 
who have suffered only the slightest—the most abstract—of injuries.”). 
24 Spokeo, 136 S. Ct. at 1549 (citing Vt. Agency of Nat. Res. v. United States ex rel. Stevens, 529 U.S. 765, 774-78 
(2000)). A qui tam action is an “action brought under a statute that allows a private person to sue for a penalty, part of 
which the government or some specified public institution will receive.” BLACK’S LAW DICTIONARY 1262 (7th ed. 
1999). Qui tam actions have a “long tradition” in England and the American colonies, dating back to the 13th century.

by observation of conduct with which one disagrees.”26 A claim based only on this sort of 
psychological discomfort will generally not support an injury-in-fact.27 
Along with the requirement of concreteness, a plaintiff’s alleged injury must be 
“particularized.”28 This requirement focuses on whether the alleged injury affects the plaintiff in a 
“personal and individual way.”29 Significantly, the need for particularization bars plaintiffs from 
seeking redress for so-called “generalized grievances.”30 Under this doctrine, a plaintiff “claiming 
only harm to his and every citizen’s interest in proper application of the Constitution and laws”31 
does not state a sufficiently particularized injury. This principle does not mean, however, that 
injuries suffered by many are not justiciable. Rather, particularization only requires plaintiffs to 
connect to the injury they allege in some particular way, even if that injury is widely shared.32 For 
instance, in Federal Election Commission v. Akins, the Supreme Court recognized that individual 
voters had suffered a justiciable injury based on the Federal Election Commission’s allegedly 
unlawful decision to not obtain and disclose certain information about a political organization.33 
The Court concluded that even though that injury was “widely shared,” the deprivation of a 
statutory right granting access to information “directly related to voting” was sufficiently 
“specific” to allow Congress to authorize individuals to vindicate that right.34 
These limitations on the courts, as they are rooted in the Constitution, are not easily 
circumvented. For example, subject to “limited exceptions,” a litigant must assert “his or her own 
legal rights and interests, and cannot rest a claim to relief on the legal rights or interests of third 
parties.”35 To illustrate, in Hollingsworth v. Perry, the Court held that the proponents of a 
California voter initiative lacked standing to defend that initiative from constitutional challenge 
when the California Attorney General declined to do so.36 In that case, the Court agreed that a

organizations, which described themselves as dedicated to promoting access of the poor to health services, could not 
establish their standing on the basis of that goal. Our decisions make clear that an organization’s abstract concern with 
a subject that could be affected by an adjudication does not substitute for the concrete injury required by [Article III].”)

created a cause of action for such violation, would not amount to “concrete” injury sufficient for standing).

“political corporate body” can designate an agent to proceed in court on its behalf, but held that 
the proponents could not simply assert to be acting in such a capacity.37 Rather, some evidence of 
actual agency, such as the principal’s right to control the agent, must be present.38 Because this 
control was lacking in Hollingsworth—the State of California had no power to control or 
authority over the proponents of the initiative—the proponents could not claim to be proceeding 
on behalf of the State, and had to rely upon their own interests, which were not sufficiently 
concrete or particularized to amount to an injury-in-fact.39  
The requirement of concrete and particular injury is essential in every case, but it is especially 
significant in cases involving the constitutionality of government action because of the important 
role that the standing doctrine plays in preserving the separation of powers. As one prominent 
treatise explains, difficult standing decisions often depend on “the importance of having the 
issues decided by the courts” versus “the importance of leaving the issues for resolution by other 
means.”40 In other words, “[s]eparation of powers concerns” often “control the seemingly precise 
concept of injury.”41 Accordingly, the Supreme Court has long recognized that the separation of 
powers is the driving force behind the standing doctrine. As the Court explained in Lujan, “the 
Constitution’s central mechanism of separation-of-powers depends largely upon common 
understanding of what activities are appropriate to legislatures, to executives, and to courts.”42 
The doctrine of standing, the Court explained, serves to identify those disputes that are 
“appropriately resolved in the judicial process.”43 Thus, while the formal standing doctrine has 
some requirements that express “merely prudential considerations,” its “core” is in ensuring that 
the courts do not stray beyond their essential role.44  
The doctrine of standing, therefore, forces the courts to police their own jurisdiction,45 preventing 
individuals from enlisting the courts in fights that should be resolved through the political 
process.46 This conception of standing helps explain why the Court has said that the standing 
inquiry is “especially rigorous” in cases involving the constitutionality of government action.47 In

jurisdiction, courts are obligated to consider sua sponte issues that the parties have disclaimed or have not presented.”).  
46 Some scholars have argued that the Supreme Court’s approach in limiting the courts to deciding on the rights of 
individuals is unjustified and forgoes the judiciary’s role in ensuring that governmental actors adhere to the 
Constitution. See, e.g., ERWIN CHEMERINSKY, FEDERAL JURISDICTION § 2.3.5 (6th ed. 2012) (“Ultimately, two 
competing visions of the role of the federal judiciary are at stake. Under one, the role of the federal courts is limited to 
remedying specific injuries suffered by individuals . . . . An alternative view sees the federal judiciary as existing to 
ensure government compliance with the Constitution . . . . This dispute is a fundamental disagreement over the role of 
the federal courts in American society.”).

such cases, the courts are being asked to participate in a dispute that may particularly involve the 
constitutional balance of power, placing the court’s role in resolving that dispute under significant 
scrutiny. 
Legislative Standing at the Supreme Court 
Separation of powers is logically the central focus when the plaintiff is a branch of government, 
such as a legislature. Although the Supreme Court has decided relatively few cases involving 
legislative standing, in those cases it articulated several principles that apply specifically when the 
plaintiff is a legislative entity.48  
The first significant Supreme Court case to involve legislators filing a lawsuit challenging a 
governmental action was the 1939 case Coleman v. Miller.49 Coleman involved the Kansas 
legislature’s then-recent approval of the proposed Child Labor Amendment to the U.S. 
Constitution, which Congress had submitted to the states for ratification 15 years prior.50 A bare 
majority of the Kansas legislature voted to ratify the amendment, with the Kansas lieutenant 
governor casting the tie-breaking vote in favor of ratification in the Kansas Senate.51 Seeking to 
undo this ratification, the plaintiffs, individual members of the Kansas legislature who had voted 
against the amendment, challenged the lieutenant governor’s right to cast his tie-breaking vote.52 
The plaintiffs argued that the lieutenant governor was not a part of the “legislature” and so his 
vote could not be counted to ratify the amendment under Article V of the Constitution.53 The 
Coleman plaintiffs also argued that the passage of time had sapped the amendment of its vitality.54 
They sued to compel the Kansas secretary of state to annul the ratification.55 
The Supreme Court splintered and issued three opinions, none of which obtained five votes.56 
However, a majority of the Court concluded that the plaintiff legislators had standing.57 Chief 
Justice Charles Evans Hughes, writing the “opinion of the Court” for himself and two other 
justices, concluded that the petitioners had an “adequate interest to invoke [the Court’s] 
jurisdiction” because the senators’ votes “would have been sufficient to defeat ratification” if they 
had been right that the lieutenant governor’s vote was invalid.58 As a result, their votes had been 
“held for naught” and “overridden,” which ran contrary to the senators’ “plain, direct and 
adequate interest in maintaining the effectiveness of their votes.”59 Justices Butler and

McReynolds dissented from the majority’s disposition of the case on the merits, but implicitly 
agreed with its conclusion that the plaintiffs had standing.60 Justice Frankfurter, writing for four 
Justices, would have held that the legislators lacked standing.61 He argued that so-called “intra-
parliamentary disputes” should be left to parliaments, and that the injuries suffered here 
“pertain[ed] to legislators not as individuals but as political representatives executing the 
legislative process.”62 If these interests were recognized, Frankfurter feared that the courts would 
end up “sit[ting] in judgment on the manifold disputes engendered by procedures for voting in 
legislative assemblies.”63 Despite these arguments, Justice Frankfurter’s view did not control, and 
Coleman is recognized as the first case in which the Supreme Court acknowledged that 
legislators’ interest in their votes may constitute an injury that could be vindicated in federal 
court. 
The Court returned to the issue of legislator standing 30 years later in Powell v. McCormack.64 In 
that case, the House Special Subcommittee on Contracts concluded that Congressman Adam 
Clayton Powell Jr., the chairman of the Committee on Education and Labor, had deceived House 
authorities as to travel expenses.65 After voters nonetheless reelected Representative Powell to the 
House of Representatives in 1966, the House adopted a resolution excluding him from taking his 
seat, and the House Sergeant at Arms refused to pay Representative Powell his salary.66 
Representative Powell sued the Speaker of the House in his official capacity, seeking a 
declaratory judgment that his exclusion was unconstitutional, an injunction restraining 
respondents from excluding him from the House, and an injunction commanding the Sergeant at 
Arms to pay Representative Powell his salary.67 After the Supreme Court elected to take review of 
the case, the Congress that had excluded Powell terminated, and Representative Powell was 
seated in the House in January 1969.68 
The Court concluded that Representative Powell’s case was justiciable.69 In particular, the Court 
looked to see if Representative Powell had a “legally cognizable interest” in the outcome of the 
case.70 The Court concluded that Representative Powell’s claim for back salary was itself 
sufficient to “supply the constitutional requirement of a case or controversy.”71 Powell thus stands 
for the proposition that legislators—no less than other individuals—have a personal pecuniary 
interest in their salary (and other personal prerogatives of office) that can amount to an injury to 
support standing when a defendant threatens that interest.72

doctrines can blur together. See, e.g., Warth v. Seldin, 422 U.S. 490, 499 n.10 (1975) (“The standing question . . . bears

The next case73 concerning legislative standing to come before the Court was 1997’s Raines v. 
Byrd.74 Raines concerned a constitutional challenge to the Line Item Veto Act of 1996, which 
purported to authorize the President to “cancel” certain spending and tax benefit measures after 
they were signed into law.75 The statute provided that “[a]ny Member of Congress or any 
individual adversely affected by [the Line Item Veto Act] may bring an action . . . for declaratory 
judgment and injunctive relief on the ground that any provision of this part violates the 
Constitution.”76 Accordingly, the day after the statute was signed into law, four Senators and two 
Members of the House, including Senator Robert Byrd, all of whom had voted against the act, 
sued under this provision alleging that the act was unconstitutional.77 Senator Byrd alleged that 
the act injured him in his official capacity in three ways: (1) by “alter[ing] the legal and practical 
effect of all votes” cast in the future on bills that would be subject to the “line item” veto; (2) by 
divesting him of his constitutional role in the repeal of legislation; and (3) by altering the 
constitutional balance of powers between the legislative and executive branch.78 
The Supreme Court held that Senator Byrd and the other legislators lacked standing to bring their 
claims.79 Chief Justice Rehnquist’s opinion for the Court emphasized that the standing inquiry 
turns, in part, on “whether the plaintiff is the proper party to bring this suit” and the requirement 
that the alleged injury be “particularized.”80 The Court’s opinion also restated the standing 
doctrine’s important role in “keeping the Judiciary’s power within its proper constitutional 
sphere” and the need to “carefully inquire” as to whether the plaintiffs had a sufficiently personal, 
particular, and concrete interest so as to justify a court’s involvement.81 Chief Justice Rehnquist 
observed that, in contrast to the plaintiff in Powell, Senator Byrd was not asserting that he was 
deprived of anything to which he was personally entitled, such as a salary. Instead, Senator Byrd 
was asserting that he had lost power as a result of the statute because it altered the balance of 
                                                 
ability of the federal courts to hear constitutional questions even where other justiciability requirements, such as 
standing, ripeness, and mootness, would otherwise be met. See Zivotofsky v. Clinton, 566 U.S. 189, 194-95 (2012) (“In 
general, the Judiciary has a responsibility to decide cases properly before it . . . . Our precedents have identified a 
narrow exception to that rule, known as the ‘political question’ doctrine.”). The political question doctrine is driven 
explicitly by separation-of-powers concerns—in one example, courts generally will find a political question where 
there has been a “textually demonstrable constitutional commitment” of a question to another branch. See Baker v. 
Carr, 369 U.S. 186, 210 (1962). In Powell, the Court found there was no political question because Article I, Section 
5’s statement that “Each House shall be the Judge of the . . . Qualifications of its own Members” only gave Congress 
the power to apply the criteria set out in the Constitution, not to invent new criteria—meaning there was no separation-
of-powers concern in overriding the House in this respect. Powell, 395 U.S. at 547-48. 
73 In between these cases, the court decided Bowsher v. Synar, 478 U.S. 714 (1986), a case challenging the 
constitutionality of the Balanced Budget and Emergency Deficit Control Act brought by Members of Congress as well 
as by members of the National Treasury Employees Union. Id. at 720-21. The Court concluded that it did not need to 
decide whether the Members independently possessed standing to bring the suit because the members of the union had 
standing, which was sufficient to satisfy the standing requirement regardless of whether the Members of Congress 
would have had standing to bring the suit by themselves. Id. at 721.

requirements by statutorily granting the right to sue to a plaintiff who would not otherwise have standing.” Id. at 820

power between Congress and the President.82 Thus, the individual legislators were, in the 
majority’s view, impermissibly attempting to assert an “institutional injury” that they shared in 
common with the entire Congress.83 Such injuries, in the form of the dilution of the power of the 
legislative body, could not give rise to standing because they were neither concrete—they were 
“wholly abstract”—nor were they particularized—they were “widely dispersed.”84  
The Court acknowledged that, in Coleman, it had upheld standing for legislators claiming a 
similar institutional injury—an interest in the effectiveness of their votes.85 However, unlike the 
plaintiffs in Coleman, Senator Byrd was not complaining that some illegal action had prevented 
his vote from counting, causing the bill to be passed in spite of his vote.86 Rather, Senator Byrd 
had voted, and he had “simply lost that vote.”87 In other words, as the Chief Justice explained, 
individual legislators could validly assert the institutional injury in Coleman only because the 
Kansas senators’ votes would have actually been enough to defeat the measure at issue, but were 
“completely nullified” by the allegedly illegal action.88 Senator Byrd, in contrast, alleged “wholly 
abstract and widely dispersed” diminution of his future voting power.89 The Court went on to 
explain that Members of Congress had an alternative remedy to their judicial challenge—they 
could repeal the Line Item Veto Act.90 Further, the Court noted that the statute was not immune 
from other judicial challenges—an individual with a cognizable injury could still bring suit.91 
Raines thus greatly limited the ability of individual legislators to sue on behalf of their 
institutions. Nevertheless, the 1997 decision reaffirmed Coleman, thereby not completely closing 
off the possibility that an individual legislator could assert an institutional injury.92 
In Raines, the Court found it “of some importance” that the various houses of Congress did not 
authorize Byrd and the other plaintiffs to bring the suit.93 Although Congress had created a right 
to challenge the statute’s constitutionality in the Line Item Veto Act itself, the plaintiffs had 
brought their suit only on their own behalf, and the plaintiffs’ respective houses of Congress as a 
whole had opposed it on the merits.94 This factor would turn out to be decisive in the next 
legislative standing case to come before the Court,95 Arizona State Legislature v. Arizona

constitutionality of the Defense of Marriage Act in lieu of the executive branch. In that case, discussed in greater detail 
infra, the majority sidestepped the standing question but several dissenting Justices adopted competing conceptions of 
legislative standing to assert an institutional injury. Justice Scalia, joined in relevant part by Chief Justice Roberts and 
Justice Thomas, contended that Congress cannot “pop immediately into court, in [its] institutional capacity, whenever 
the President . . . implements a law in a manner that is not to Congress’s liking.” Id. at 789 (Scalia, J., dissenting).

Independent Redistricting Commission.96 In that case, the Arizona state legislature—as a whole—
sued the Arizona Redistricting Commission (Commission), an independent commission vested by 
popular initiative with the authority to draw redistricting maps for congressional districts.97 The 
Arizona legislature sought to challenge the map adopted by the Commission for the 2012 
elections as unconstitutional. 98 The Arizona legislature argued that, under the Elections Clause of 
the Constitution, the “Legislature” of a state had to have “primary responsibility” to set the 
manner of elections, and the Commission did not qualify as a legislature.99 
The Court concluded that, in contrast with the individual Member plaintiffs in Raines, the 
Arizona legislature had standing. The Court found that the key difference between the Arizona 
legislature and the plaintiffs in Raines was that the former was “an institutional plaintiff asserting 
an institutional injury [that had] commenced this action after authorizing votes in both of its 
chambers.”100 The problem with the individual Members asserting institutional injury in Raines, 
as the Arizona State Legislature Court saw it, was that the injury was “widely dispersed,” and no 
plaintiff in the 1997 case could “tenably claim a personal stake in the suit.”101 In contrast with 
Raines, the Court concluded, Arizona State Legislature was closer to the Coleman facts, in that 
the Commission’s authority “completely nullif[ied]” any vote by the legislature purporting to 
adopt a redistricting plan—and that injury was adequately particularized to the plaintiff that was 
bringing the suit.102 Importantly, however, the Court stated in a footnote that the standing inquiry 
might have been different had the suit involved Congress mounting a legal challenge to the 
President, which would have raised “separation-of-powers concerns absent here.”103 
A few key principles can be drawn from this line of Supreme Court cases. With respect to cases 
brought by individual legislators, Raines drew a fundamental distinction between so-called 
“institutional injury” and the sort of personal injury that was at issue with the plaintiff’s lost 
salary in Powell.104 As the Court would go on to explain in Arizona State Legislature, an 
“institutional injury” is an injury that “scarcely zeroe[s] in on any individual member,” but rather 
“impact[s] all Members of Congress and both Houses . . . equally.”105 The Arizona State 
Legislature court, interpreting Raines, explained that individual legislators generally cannot assert 
institutional injuries: “[h]aving failed to prevail in their own Houses, the suitors [in Raines] could 
not repair to the Judiciary to complain.”106 However, Raines also determined that there was an 
                                                 
According to this view, Congress may not “hale the Executive before the courts” merely “to correct a perceived 
inadequacy in the execution of its laws;” instead, a legislative plaintiff possesses standing only to vindicate interests 
that are unique to Congress. Id. Justice Alito, by contrast, took the slightly broader view that Congress potentially 
possesses standing to participate in federal litigation whenever it faces “impairment” of its “central [legislative] 
function,” as may occur if the executive branch opts not to defend a federal statute from a constitutional challenge. Id. 
at 805 (Alito, J., dissenting). This report analyzes these competing positions in greater detail infra at “Congressional

exception to this general rule based on the Court’s holding in Coleman v. Miller, “[t]he one case 
in which [the Court] upheld standing for legislators . . . claiming an institutional injury.”107 The 
Court justified this exception because the plaintiffs in Coleman, if they had been correct on the 
merits of their claim, would have been in a situation where “their votes not to ratify the 
amendment were deprived of all validity.”108 The challenge, then, for any individual legislator 
asserting an institutional injury is to show that the asserted injury is analogous to the “vote 
nullification” that took place in Coleman.109 These principles will be discussed in the next section. 
Individual Legislators and Standing in the 
Lower Courts 
Institutional Injury 
Much of the lower court case law on legislative standing has focused on when an individual can 
assert an institutional injury akin to the injury asserted by the plaintiffs in Coleman. The courts 
inside and outside the D.C. Circuit110 have taken slightly different approaches to analyzing this 
question. 
The District of Columbia Circuit 
Because Members of Congress serve in the federal government in Washington, D.C., and because 
the District is also the site of executive branch actions that could be the subject of a congressional 
lawsuit, such cases are often initiated in D.C. federal court. As a result, the federal appellate body 
in D.C., the D.C. Circuit—often referred to as the second most important court in the 
country111—has a significant influence over the case law concerning congressional standing.112  
In a pair of cases following Raines, the D.C. Circuit considered when individual Member 
plaintiffs can assert institutional injuries: the 1999 case Chenoweth v. Clinton,113 and the 2000 
case Campbell v. Clinton.114 In Chenoweth, three Members of the House sued to enjoin the 
American Heritage Rivers Initiative (AHRI), a program promulgated by executive order that 
required certain federal agencies to support local efforts to preserve certain historically significant 
rivers and riverside communities.115 The Member plaintiffs argued that the AHRI violated the 
Constitution by depriving them of their constitutional role in the passage of legislation by creating

the AHRI via executive order.116 The Members argued that their injury was more severe than the 
injury at stake in Raines because the President’s action had “denied Members of Congress any 
opportunity to vote for or against the AHRI.”117 The D.C. Circuit disagreed, concluding instead 
that the injury asserted by the plaintiffs in Chenoweth was fundamentally the same as that 
asserted in Raines—that their injury was an “alter[ation] [in] the constitutional balance of powers 
between the Legislative and Executive Branches.”118 Further, the court observed that here, as in 
Raines, it was “uncontested that the Congress could terminate the AHRI were a sufficient number 
in each House so inclined,” meaning that, as in Raines, Congress had a legislative remedy.119 The 
Chenoweth court acknowledged that, following Coleman, it might be a different case if the 
Representatives alleged that the necessary majorities in Congress had voted to block the AHRI.120 
In such a case, legislators could argue that their votes had been “effectively nullified,” but 
because plaintiffs in Chenoweth made no such allegations, the court dismissed the case for want 
of standing.121 
The second of the influential post-Raines D.C. Circuit decisions is Campbell v. Clinton, decided 
the year after Chenoweth.122 That case challenged the legality of the United States’ involvement 
in NATO air and cruise missile attacks in Yugoslavia.123 Prior to the lawsuit, Congress had voted 
on four resolutions related to the conflict, including an “authorization” of the air strikes that failed 
by a tie vote, 213-213, and a declaration of war that failed 427-2.124 Congress also voted against 
requiring the President to immediately end U.S. participation in the conflict and voted to fund the 
involvement.125 After these votes, the plaintiffs, 31 Members of Congress who were opposed to 
U.S. military involvement filed suit, alleging that the President’s use of American forces violated 
the Constitution’s War Powers Clause and the War Powers Resolution.126 Representative Tom 
Campbell and the other Member plaintiffs argued that the Executive’s action had “completely 
nullified” the tie vote against the airstrikes and the vote against the declaration of war, equating 
themselves to the Kansas senators in Coleman.127  
The D.C. Circuit disagreed, concluding that the reason the Coleman plaintiffs’ votes had been 
“nullified” was because of the unique context of a vote against a constitutional amendment,

121 Id. at 116-17. Prior to Raines, the D.C. Circuit had developed a complex edifice of case law surrounding legislative 
standing, essentially separating standing analysis from a doctrine of “equitable discretion,” which allows a court to 
decline to hear a case when necessary to avoid an “intrusion by the judiciary into the legislative arena.” See id. at 114 
(citing Riegle v. Fed. Open Mkt. Comm., 656 F.2d 873, 881 (D.C. Cir. 1981)). In Chenoweth, the D.C. Circuit 
recognized that significant portions of these cases were “untenable” after Raines, which left “no room” for the “broad 
theory of legislative standing” adopted in previous cases and likely required the court to merge its standing and 
equitable discretion doctrines. See id. at 115-16 (citing Moore v. U.S. House of Representatives, 733 F.2d 946 (D.C.

which left them without any alternative remedy.128 The appellate court argued that, in Coleman, 
the Kansas senators were in a unique position because they were “powerless” to rescind the 
ratification by legislative action—according to the court, it was “not at all clear” whether the 
ratification could have been rescinded once it was deemed ratified.129 The court saw Raines as 
having attached critical importance to this absence of legislative remedy; this fact is what 
“nullified” the Kansas senators’ votes and supplied the necessary concrete injury.130 In contrast, 
the Campbell plaintiffs had several legislative remedies, including the power to withdraw 
appropriations and impeachment.131 As a result, the court concluded that their vote had not been 
“nullified” in the same manner as the Coleman plaintiffs. Rather, the court viewed the Campbell 
plaintiffs’ argument to essentially be that the President acted illegally in excess of his 
constitutional authority and in violation of a statute.132 As a result, the circuit court determined 
that the case was indistinguishable from Raines, and the plaintiffs had not suffered a concrete and 
particularized injury. 
Following these precedents, the trial courts in the D.C. Circuit have generally been hesitant to 
find concrete and particularized injury in cases involving individual legislators asserting 
institutional injuries, especially where the legislature as a whole possessed other potential 
avenues for relief through the legislative process. For example, in 2002, the court concluded that 
32 Members of the House of Representatives lacked standing to challenge President George W. 
Bush’s unilateral withdrawal from 1972’s Anti-Ballistic Missile Treaty.133 As in Campbell, the 
court emphasized the “widely dispersed” nature of the injury and the “extensive self-help” 
remedies available to Congress that could be used to remedy the President’s allegedly illegal 
actions, such as the appropriations power, or, as a last resort, impeachment.134 The court 
concluded that the availability of these alternate remedies, combined with the fact that Congress 
as a whole had not authorized these individual Members to represent its interests in federal 
litigation, demonstrated that the plaintiffs could not assert the institutional injury alleged.135 
Similarly, in a 2011 case, a D.C. district court determined that 10 Members of the House lacked 
standing to challenge President Obama’s alleged violation of the War Powers Clause of the 
Constitution and the War Powers Resolution.136 In that case, the plaintiffs alleged that the 
President had pursued military action in Libya without seeking any approval from Congress and 
had spent funds on an “unauthorized war.”137 The court, again following Campbell, emphasized 
that “nullification necessitates the absence of a legislative remedy” and found that the plaintiffs 
had “voted on essentially what the plaintiffs now ask this Court to award . . . . Thus, the plaintiffs’ 
votes were given full effect. They simply lost that vote.”138

Congressional Participation in Litigation: Article III and Legislative Standing 
 
The one post-Raines ruling from a D.C. district court to reach a contrary conclusion and find 
legislative standing was the 2018 case Blumenthal v. Trump.139 The plaintiffs in Blumenthal—
approximately 201 minority Members of the Senate and House—alleged that President Donald 
Trump, by receiving benefits from his business entities’ dealings with foreign governments, had 
violated the Foreign Emoluments Clause of the Constitution, which prohibits persons holding 
certain offices from receiving any “present, Emolument, Office, or Title, of any kind whatever, 
from any King, Prince, or foreign State.”140 Plaintiffs sought declaratory as well as injunctive 
relief preventing the President from accepting any further emoluments without the consent of 
Congress.141 The plaintiffs argued that they had suffered injury because the President’s conduct, 
in allegedly accepting emoluments and failing to submit those emoluments to Congress, had 
nullified their votes by “den[ying] them a voting opportunity to which the Constitution entitles 
them.”142  
The district court reasoned that, although this injury was an institutional injury dispersed among 
all Members of Congress, it nonetheless was comparable to the injury upheld in Coleman because 
the plaintiffs in Blumenthal, like the plaintiffs in Coleman, were not complaining about dilution 
of legislative power, but rather about the complete nullification of their votes.143 This distinction 
turned decisively on the plaintiffs’ lack of a legislative remedy.144 The Blumenthal court 
contrasted the case with Raines and Chenoweth, in which the plaintiffs “either lost the vote in 
Congress or did not have the political influence to bring their bill to a vote.”145 By contrast, in the 
view of the district court, Senator Blumenthal and the other Member plaintiffs lacked any 
legislative means to remedy their complaints because the President never provided them with the 
opportunity to approve the emoluments in the first place.146 Although the defendants suggested 
several potential nonjudicial remedies, such as a vote by Congress rejecting specific supposed 
emoluments, or a bill defining emoluments and prohibiting the receipt of them, the court went on 
to reject all of these proposed possible legislative remedies as inadequate, asserting that none 
would require the President to submit his emoluments for congressional consent for prior 
approval or even force him to provide information about future emoluments to Congress.147 
Further, the court determined that appropriations remedies that the D.C. Circuit saw as adequate 
in Campbell and Chenoweth would not work in this case, as there are no federal appropriations

associated with the President’s alleged receipt of emoluments.148 Finally, the court concluded that 
impeachment was too “extreme” to be considered an adequate remedy.149  
Institutional Injury to Individual Legislators Outside the D.C. Circuit 
Whereas the D.C. Circuit and the U.S. District Court for the District of Columbia have generally 
concluded that whether individual legislators possess standing largely turns on the availability of 
alternative legislative remedies,150 other circuits considering the question have not arrived at the 
same consensus. These courts have generally viewed the Coleman exception even more narrowly 
than the D.C. Circuit, further limiting the availability of legislative standing.151 
In Baird v. Norton, for example, the Sixth Circuit ruled that Members of the Michigan state 
legislature lacked standing to challenge the procedures followed by their legislature in approving 
certain gaming compacts between the State of Michigan and Indian tribes.152 The plaintiffs 
alleged that the legislature had unlawfully approved the gaming compacts without complying 
with certain procedural safeguards required by the Michigan Constitution.153 First, the court held 
that the procedural harm inflicted by this neglect of constitutional procedures was only a 
“generalized grievance shared by all Michigan residents” and could not give rise to standing.154 
Second, in response to the argument that the use of these procedures had “nullified” the plaintiffs’ 
votes in the legislature, the court, analyzing Raines and Coleman, concluded that “[f]or legislators 
to have standing as legislators, then, they must possess votes sufficient to have either defeated or 
approved the measure at issue.”155 As this court read Coleman, standing required that the lawsuit 
be joined by sufficient members of their respective houses to defeat the legislation in order to 
                                                 
148 Id. at 68. 
149 Id. The court acknowledged that its holding was at least somewhat in tension with a previous D.C. District Court 
case, Kucinich v. Bush, 236 F. Supp. 2d 1 (2002), which, as explained above, had concluded that Members of Congress 
did not have standing to sue the President about the President’s unilateral withdrawal from a treaty. See Blumenthal, 
335 F. Supp. 3d at 61 n.7. The Blumenthal court justified this by arguing that Kucinich “did not discuss whether the 
plaintiffs’ votes had been nullified.” Id. While the Kucinich case did not discuss ‘nullification’ explicitly in those terms, 
the case did discuss Campbell and concluded that Representative Dennis Kucinich and the other Members plaintiffs 
had “extensive” self-help remedies available. Kucinich, 236 F. Supp. 2d at 10. The court argued, for example, that 
though the appropriations power or legislation could not be used directly to affect the President’s withdrawal from the 
treaty, it could be used to “influence the President’s actions.” Id. at 10-11. The difference between Kucinich and 
Blumenthal appears to be driven, at least in part, by the judges’ differing views on the effectiveness of such indirect 
legislative remedies in these different contexts. 
150 See, e.g., Campbell v. Clinton, 203 F.3d 19, 23 (D.C. Cir. 2000) (characterizing Coleman as “narrow . . . exception” 
to Raines that applies only when votes are “nullified” but does not apply to situations where Congress “enjoy[s] ample 
legislative power”). But see Cummings v. Murphy, 321 F. Supp. 3d 92, 112 (D.D.C. 2018) (arguing that “[t]his court is 
not of the view that complete vote nullification is the only instance in which an individual legislator can assert 
institutional injury” and analyzing historical practice, congressional authorization, and alternative remedies in 
determining whether institutional injury is sufficiently concrete and particularized). 
151 The Third Circuit has seemingly, albeit in a different context, adopted the view of the D.C. Circuit that the 
availability of an alternative legislative remedy is the key factor in considering legislative standing. In Russel v. 
DeJongh, 491 F.3d 130, 135-36 (3d Cir. 2007), a Virgin Islands senator sought to sue the governor over his alleged 
failure to timely submit nominations to the Islands’ Supreme Court. Id. The court held that there was no standing 
because the Virgin Islands’ legislature “was free to confirm, reject, or defer voting on the Governor’s nominees.” Id. at 
136. The court concluded that this alternative legislative option took the plaintiffs’ injury out of the category of “vote 
nullification.” Id.

show that actual nullification occurred.156 Because the legislators in Baird could not make that 
showing, the court concluded that they lacked standing without examining the availability of 
alternative legislative remedies.157 
Reading Raines even more narrowly, the Tenth Circuit has concluded that individual legislators 
can never bring suit to assert institutional injuries.158 In Kerr v. Hickenlooper, on remand to the 
Tenth Circuit after the Supreme Court’s decision in Arizona State Legislature,159 the court 
considered whether then-current Colorado state legislators could have standing to challenge an 
amendment to the Colorado Constitution that required voter approval in advance for new taxes.160 
The Tenth Circuit had previously concluded that the legislators had standing because this 
amendment “deprive[d] them of their ability to perform the legislative core functions of taxation 
and appropriation,” rendering their votes “advisory.”161 On remand, however, the court changed 
its view, and read Raines and Arizona State Legislature together to conclude that “individual 
legislators may not support standing by alleging only an institutional injury,” which only 
institutional plaintiffs like the Arizona state legislature could assert.162 Arizona State Legislature, 
the court determined, had changed the law such that the nature of the injury—whether it was 
personal or institutional—was the determinative factor.163 The Tenth Circuit concluded that 
Coleman, which Raines had characterized as an institutional injury case, was in fact a case 
involving a “personal” injury to the senators whose votes were allegedly nullified.164 This injury 
was not, in the Tenth Circuit’s view, “institutional” as the Supreme Court used that term in 
Arizona State Legislature because institutional injuries necessarily affect all members of a 
legislature in equal measure, and in Coleman, the only injured legislators were those who had 
their votes nullified.165 As a result, the court concluded that the plaintiffs in Kerr had asserted 
only institutional injuries to the power of the legislature, and they accordingly lacked standing.166 
The views on institutional injuries announced in Baird and Kerr appear to contrast with the 
somewhat more receptive standard that has developed in the D.C. Circuit. In both Baird and Kerr, 
the court interpreted the standing upheld in Coleman, the so-called vote nullification injury, as 
being about the deprivation inflicted on individual legislators by virtue of their vote being 
defeated by the allegedly unlawful action.167 In contrast, after Campbell, the D.C. Circuit has

implementation of the Foreign Account Tax Compliance Act by way of intergovernmental agreements, which he 
alleged the Executive should have submitted to the Congress for approval, thus depriving him of his constitutional right 
to vote for or against the agreements. Id. at 444. Relying on Baird, the Court held that Senator Paul lacked standing 
because he lacked the votes sufficient to repeal the Act in question. Id. at 454.

focused on the lack of a legislative remedy and whether the legislature as a whole continues to 
enjoy “ample legislative power” to remedy the alleged wrong.168 
Personal Injury 
As the Supreme Court explained in Raines, there may be fewer obstacles for legislators to sue for 
“something to which they are personally” entitled, such as the loss of salary claimed by 
Representative Powell in Powell v. McCormack.169 This section examines how lower courts have 
distinguished between “personal” and “institutional” injuries and the other justiciability 
considerations that have been applied to injuries that were undoubtedly personal. 
Distinguishing Personal from Institutional Injuries 
In Raines and Arizona State Legislature, the alleged injuries were clearly institutional because the 
alleged wrongful conduct represented diminution in the power of the legislature as a whole, 
affecting “all Members of Congress and both Houses . . . equally.”170 However, it is possible for 
an injury to have apparently unequal effects within the legislature but nonetheless be 
“institutional.” Best illustrating this principle is a pair of cases from different districts considering 
claims brought under 5 U.S.C. § 2954—which provides that executive agencies, on request of the 
House Committee on Oversight and Reform or the Senate Homeland Security and Governmental 
Affairs Committee, or “any seven members thereof,” “shall submit any information requested of 
it relating to any matter within the jurisdiction of the committee.”171 Known as the “Seven-
Member Rule,”172 this statute authorizes Members of the minority party to obtain information 
from the administration, but does not provide explicitly for judicial enforcement.173  
In Waxman v. Thompson, a 2006 case out of the Central District of California, 18 Members of the 
House sued under Section 2954 after they had received an allegedly incomplete response from the 
Executive to their demand for documents relating to the anticipated cost of the Medicare 
Prescription Drug and Modernization Act of 2003.174 The court determined that the plaintiffs had 
not shown that their vote had been nullified within the meaning of Coleman—plaintiffs had 
                                                 
demonstrate that her vote was sufficient to defeat the compacts had the constitutionally required procedure been 
followed. Because Baird cannot do so, she lacks standing.”). See also Corman v. Torres, 287 F. Supp. 3d 558, 568 
(M.D. Pa. 2018) (holding that state legislative leaders had no standing to challenge state supreme court’s redrawing of 
election districts as usurpation of authority under Elections Clause; observing important fact that legislative leaders 
could not command two-thirds majority necessary in both chambers to override a gubernatorial veto, and that “[t]wo 
votes could not on their own have defeated or enacted any proposed remedial redistricting legislation”).

was moot in light of Carter v. United States Department of Commerce, 307 F.3d 1084 (9th Cir. 2002)).

alleged only that they “ha[d] been required to vote and legislate without full access to 
information.”175 The plaintiffs, however, argued that their injury was personal, not institutional, 
because they had a “distinct legal entitlement not shared by all Members of Congress.”176 The 
court disagreed. Rather, the court explained, the right the plaintiffs asserted “runs with their 
congressional and committee seats.”177 Their injury, in the view of the court, was not an injury to 
themselves personally, but an injury to “Congress, on whose behalf they acted,” and it was the 
same type of institutional injury that the Supreme Court deemed insufficient to confer standing in 
Raines.178  
This same issue arose again in 2018, in the case Cummings v. Murphy in the U.S. District Court 
for the District of Columbia.179 As in Waxman, the Cummings plaintiffs were minority Members 
of the House Oversight Committee who sought documents from an executive agency under 
Section 2954.180 The court observed that the “Plaintiffs tie[d] their injury directly to their 
constitutional duties as legislators, claiming their alleged harm to be impedance of the oversight 
and legislative responsibilities that have been delegated to them by Congress” and that the injury 
alleged ran “in a sense with the Plaintiff’s seat.”181 Despite these facts, the plaintiffs argued, as in 
Waxman, that because their injury was not shared by all Members of Congress equally, their 
injury was not institutional in nature.182 The court disagreed. Relying on Raines, the court 
concluded that the plaintiffs’ injury was institutional because it was “rooted in a right granted to 
them as Members of Congress.”183 Further, because any violation of the “Seven-Member Rule” 
was an institutional injury, the court determined that, although the Member plaintiffs had a 
“stronger case” for standing than the plaintiffs had in Raines, historical practice, a lack of 
congressional authorization, and the availability of alternative remedies demonstrated that the 
injury was too “wholly abstract” and “widely dispersed” to confer standing on an individual 
Member.184 
These cases make clear that the difference between a “personal” and an “institutional injury” does 
not hinge on the issue of particularization. Rather, the difference is the source of the right that has 
been violated. The Seven-Member Rule cases demonstrate that, even where an injury has a 
particular effect on certain Members, it can nonetheless be insufficiently “concrete” under Raines 
if the Member’s injury does not deprive him of something to which he is personally entitled.185 In 
other words, where the right alleged to have been violated is tied to a right granted to a plaintiff

“as [a] Member[] of Congress,” all of Congress is harmed equally, as a diminution of that right 
affects the institution as a whole, even if it is only a single Member who is asserting that right at a 
given moment.  
Personal Injury Must Comply with Traditional Standing Requirements 
Even if a legislator alleges an injury that seems to be genuinely “personal” rather than 
“institutional,” that injury must nonetheless meet the typical standing requirements of 
particularization and concreteness.186 Further, that injury must be likely and imminent as opposed 
to merely speculative, causally connected to the challenged action, and redressable by the 
court.187 A number of cases illustrate how an alleged injury to legislators can fail to meet these 
requirements. 
For example, post-Raines, federal courts of appeals have generally concluded that a mere 
possibility of electoral or reputational harm to a legislator is too speculative to support Article III 
standing.188 In Schaffer v. Clinton, the Tenth Circuit dismissed a claim brought by Representative 
Bob Schaffer, a Member of Congress who alleged that the cost of living adjustment (COLA) in 
the Ethics Reform Act of 1989 violated the 27th Amendment to the Constitution.189 
Representative Schaffer, who received an increase in pay based on the COLAs, argued that they 
were “damaging to his political position and his credibility among his constituency” because the 
COLAs involved paying him with monies allegedly “appropriated unconstitutionally.”190 This 
argument relied heavily on a pre-Raines D.C. Circuit case, Boehner v. Anderson.191 In Boehner, 
the D.C. Circuit had concluded that Congressman John Boehner had standing to challenge the 
COLAs based on his claim that it undermined his “political position.”192 However, as the Tenth 
Circuit observed, this case predated Raines, and its analysis was “cursory.”193 Rejecting Boehner, 
the Tenth Circuit concluded that Congressman Schaffer’s asserted injury was supported by no 
concrete evidence of reputational injury and was much like the injury rejected in Raines—an

188 At least one court has concluded that legislators attempting to assert injuries as a representative of their constituents 
lack a sufficiently concrete injury. In the 2002 case Kucinich v. Defense Finance & Accounting Service, 183 F. Supp. 
2d 1005 (N.D. Ohio 2002), Congressman Kucinich sued an agency of the Department of the Defense, alleging that it 
had violated federal law and the Constitution by awarding a contract that would have caused displacement of workers 
and job losses in his district. Id. at 1006. The court concluded that because allowing Representatives to challenge 
executive action on behalf of their constituents would raise “grave separation-of-powers dangers,” Congressman 
Kucinich’s remedy resided with Congress. Id. at 1011-12. 
189 Schaffer v. Clinton, 240 F.3d 878, 880 (10th Cir. 2001). The 27th Amendment states that “No law, varying the 
compensation for the services of the Senators and Representatives, shall take effect, until an election of Representatives 
shall have intervened.” U.S. CONST. amend. XXVII. 
190 Schaffer, 240 F.3d at 885. Congressman Schaffer also raised two other arguments, neither of which was sufficient to 
give rise to standing. First, he argued that he was harmed by “personal offense,” but generally speaking, the 
“psychological consequence presumably produced by observation of conduct with which one disagrees” is not a 
sufficient injury to convey Article III standing. Id. at 884. Second, he argued that the COLAs harmed him 
“professionally” because they affected his pay. Id. However, the court held that this alleged injury did not suffice 
because the COLAs increased his pay, not decreased it. Id. at 884-85.

abstract claim that applied to every Member of Congress.194 As a result, the injury alleged was 
insufficiently concrete and particularized to give rise to standing.195 
Another pair of cases illustrates how alleged injuries to legislators can fail to meet standing 
requirements on causation and redressability, even if the injuries alleged are seemingly 
sufficiently concrete and particular. The first of these cases is a 2018 case from the Middle 
District of Pennsylvania, Corman v. Torres.196 Corman involved a challenge brought by several 
parties to the Pennsylvania Supreme Court’s 2018 decision to strike the 2011 redistricting map 
and issue its own replacement map.197 Among the challengers were eight Republican Members of 
Pennsylvania’s delegation to the U.S. House of Representatives, who challenged the 
Pennsylvania Supreme Court’s decision as a violation of the Elections Clause of the 
Constitution.198 The Members argued that they were injured by the alterations to their districts, 
thereby reducing their incumbency advantage, and by wasting time, energy, and resources 
expended in their former districts.199 The court set aside the question of whether these injuries 
were sufficiently concrete and particular, but nonetheless observed that no case supported “the 
proposition that an elected representative has a legally cognizable interest in the composition of 
his or her electoral district.”200 Irrespective of this question, the court concluded that the 
Members’ claim failed on the causation prong of standing. Because the plaintiff Members 
conceded that the state supreme court had the authority to order the redrawing of the redistricting 
map, they could not trace their injuries to the substantive decisions that actually led to the court-
drawn map:  
Even if the Pennsylvania Supreme Court had simply ordered that a new redistricting map 
be drawn, but had given the General Assembly free substantive rein . . . to accomplish that 
objective,  the  .  .  .  injury  would  persist.  In  that  circumstance,  the  court  would  not  have 
committed  any  of  the  improprieties  alleged  in  the  verified  complaint,  but  district 
boundaries would still have changed.201  
The court concluded that the plaintiffs could not bridge this “gap” in the causal chain and 
dismissed the Members’ claims.202 
Another case in which a legislator’s purported claims could not overcome the second two 
elements of the standing inquiry is Rangel v. Boehner, a 2013 case out of the District Court for

Personnel Management, 783 F.3d 655, 666-69 (7th Cir. 2015). In Johnson, Senator Ron Johnson sought to challenge 
an OPM rule allowing members of Congress and their staffs to take advantage of an Affordable Care Act insurance 
exchange reserved for small businesses. Id. at 658. The court concluded that “[t]he possibility of electoral or 
reputational harm, therefore, is much too ‘conjectural or hypothetical’ to establish Article III standing.” Id. at 669

the District of Columbia.203 Rangel arose out of disciplinary proceedings and a vote of censure 
against Congressman Charles Rangel.204 Representative Rangel alleged that certain improprieties 
had colored the proceedings of the Ethics Committee that had investigated him. He sued officials 
of the House, but not the House itself, seeking declaratory relief and an injunction requiring the 
defendants to “remove the recording of censure.”205 Representative Rangel claimed four separate 
injuries that he argued gave rise to standing: damage to his reputation,206 the loss of his status on 
the House Ways and Means Committee,207 “political injury,”208 and a violation of his due process 
rights.209 On these alleged injuries, the court generally concluded that Representative Rangel’s 
claims failed on grounds of lack of causation and redressability. For example, although the court 
had no doubt that alleged injury to Representative Rangel’s reputation was sufficiently concrete 
and particularized, the plaintiff’s failure to sue the House itself doomed his ability to show 
causation. After all, the actions of the individual defendant House Members did not cause his 
injury—it was, as the court noted, the House that censured him, not the individual Member 
defendants.210 Similarly, Representative Rangel was unable to demonstrate redressability because 
the court determined that it had no authority to order the House to rescind his censure, as 
authority over the House’s Journal was constitutionally vested in the House itself.211 As a 
consequence, a legislator plaintiff having a concrete and particularized injury is not alone 
sufficient to establish Article III standing, especially when the plaintiff seeks to involve the court 
in the internal affairs of the other branches of government. 
Institutional Standing 
The Supreme Court’s decision in Arizona State Legislature v. Arizona Independent Redistricting 
Commission reinforces that an institutional plaintiff, like the Arizona state legislature, will 
typically have standing to assert an “institutional injury.”212 In that case, discussed above, the 
Court determined that the Arizona state legislature had standing based on the Redistricting 
Commission’s usurpation of its “primary responsibility” for redistricting under the Constitution’s 
Elections Clause.213 Although the Court concluded that the legislature did not, in fact, have the 
exclusive authority it alleged, the Court nonetheless determined that this merits determination did 
not undercut the legislature’s claim of injury for the purposes of justiciability.214 This analysis 
indicates that an institution, such as a legislature as a whole, may potentially assert an 
institutional injury and obtain standing in federal court. The Court left open, however, the

possibility that separation-of-powers considerations could lead to a different result if the case 
instead involved Congress suing the President.215  
In addition to the separation-of-powers concerns that might arise, Arizona State Legislature raises 
questions regarding who constitutes an institutional plaintiff and which institutional injuries are 
sufficiently concrete and particularized to give rise to standing.216 These questions are the focus of 
the following sections. 
The Significance of Explicit Congressional Authorization 
Courts have routinely concluded that congressional plaintiffs who obtain authorization to sue 
before initiating litigation217 are significantly more likely to have standing.218 As one court has 
explained, the presence of authorization is the “key factor” when determining whether a 
congressional plaintiff possesses standing to vindicate an institutional injury on behalf of the 
authorizing institution.219 When a legislative plaintiff possesses authorization to pursue litigation 
from its respective institution, it decreases the likelihood that the plaintiff is impermissibly 
attempting to assert the rights of a third party instead of proceeding on the institution’s behalf.220 
Although the Arizona State Legislature Court deemed it important that the legislative plaintiffs 
commenced the lawsuit after “authorizing votes in both of its chambers,”221 that does not mean 
that a congressional plaintiff must always obtain the imprimatur of both the Senate and the House 
of Representatives in order to bring suit. Rather, courts have held that a plaintiff may sue on 
behalf of a single house of Congress to vindicate that particular chamber’s unique institutional 
interests.222 
                                                 
215 See id. at 2665 n.12 (“The case before us does not touch or concern the question whether Congress has standing to 
bring a suit against the President. There is no federal analogue to Arizona’s initiative power, and a suit between 
Congress and the President would raise separation-of-powers concerns absent here. The Court’s standing analysis, we 
have noted, has been ‘especially rigorous when reaching the merits of the dispute would force [the Court] to decide 
whether an action taken by one of the other two branches of the Federal Government was unconstitutional.’”) (quoting 
Raines v. Byrd, 521 U.S. 811, 819-20 (1997)). 
216 Id. at 2665 (holding that the Legislature’s injury was sufficiently concrete because the Redistricting Commission’s 
authority “completely nullif[ied]” any vote of the Legislature nor or in the future). 
217 The applicable procedure for obtaining congressional authorization to file and pursue a lawsuit varies depending on 
the circumstances. See, e.g., 2 U.S.C. § 288b(b) (“[Senate Legal Counsel] shall bring a civil action to enforce a 
subp[o]ena of the Senate or a committee or subcommittee of the Senate . . . only when directed to do so by the adoption 
of a resolution by the Senate.”). 
218 See, e.g., Ariz. State Legislature, 135 S. Ct. at 2664; Comm. on the Judiciary, U.S. House of Representatives v. 
Miers, 558 F. Supp. 2d 53, 71 (D.D.C. 2008).

or her own legal rights and interests, and cannot rest a claim to relief on the legal rights or interests of third parties.”) 
(quoting Powers v. Ohio, 499 U.S. 400, 410 (1991)), with, e.g., United States v. Am. Tel. & Tel. Co., 551 F.2d 384, 
391 (D.C. Cir. 1976) (“The House of Representatives . . . authoriz[ed] Chairman Moss’s intervention on behalf of the

can designate a member to act on its behalf.”).

the House is but one chamber of Congress, and the Senate is not a plaintiff in this suit . . . Yet the House remains an 
institution claiming an institutional injury . . . The Court finds that the injury, although arguably suffered by the House 
and the Senate alike, is sufficiently concentrated on the House to give it independent standing to sue.”). See also, e.g.,

Several courts have considered what sort of authorization, short of authorizing votes in both 
chambers leading to a suit being brought by the institution itself, suffices to permit a suit on 
behalf of a legislative institution. A number of cases prior to Arizona State Legislature considered 
this question. The most common setting for these cases involved legislative demands for 
information. The Supreme Court has long recognized “that the power of inquiry—with process to 
enforce it—is an essential and appropriate auxiliary to the legislative function.”223 In other words, 
Congress has an interest in obtaining information necessary to fulfill its constitutionally 
designated role in the tripartite system of American government.224 At the same time, however, 
courts have acknowledged a distinction between a chamber of Congress utilizing its own powers 
to demand and obtain information and invoking the federal courts’ power to enforce its 
demands.225 In order to utilize the judicial process—rather than the political process—to enforce 
congressional demands for information, Supreme Court precedent requires the plaintiffs to show 
that they are validly acting on behalf of the injured institution.226 
In the 1976 case of United States v. AT&T Co., for instance, the D.C. Circuit ruled that the 
chairman of the House Subcommittee on Oversight and Investigations had standing to appear in 
federal court to challenge the executive branch’s objection to a subpoena that the subcommittee 
had issued to a private party.227 The court reasoned “that the House as a whole has standing to 
assert its investigatory power, and can designate a member to act on its own behalf.”228 Crucially, 
because the House of Representatives had passed a resolution authorizing the chairman to 
participate in the case “on behalf of the Committee and the House,” the chairman did not 
encounter the standing obstacles that might exist if “a single [M]ember of Congress” attempted 
“to advocate his own interest in the congressional subpoena power” without the affirmative 
consent of his or her respective chamber229 or if “a wayward committee” were “acting contrary to 
the will of the House.”230 Although AT&T predates Raines and the subsequent D.C. Circuit cases 
interpreting it, courts have generally concluded that AT&T’s holding—namely, that congressional 
plaintiffs usually have standing to assert Congress’s interests in obtaining information so long as 
they have congressional authorization to do so—survives Raines.231 AT&T’s holding comports 
                                                 
(concluding that “the House of Representatives” by itself had “pleaded a legally cognizable injury and satisfied Article 
III”). 
223 See McGrain v. Daugherty, 273 U.S. 135, 174 (1927). 
224 See id. 
225 See, e.g., Reed v. Cty. Comm’rs of Del. Cty., Pa., 277 U.S. 376, 389 (1928) (“Authority to exert the powers of the 
Senate to compel production of evidence differs widely from authority to invoke judicial power for that purpose.”). 
226 See, e.g., id. (“[T]he Senate did not intend to authorize the committee . . . to invoke the power of the Judicial 
Department. Petitioners are not authorized by law to sue.”). 
227 551 F.2d at 385-85, 387, 391. AT&T involved a congressional attempt to intervene in an ongoing lawsuit as a 
defendant, rather than an attempt to initiate a lawsuit as a plaintiff. See id. at 387 (“The Justice Department . . . brought 
an action in the name of the United States . . . and obtained a temporary restraining order prohibiting AT&T from 
complying with the Subcommittee subpoena. Chairman Moss was allowed to intervene as a defendant.”). In line with 
the case law on intervention, see infra “Congressional Intervention to Defend a Statute’s Constitutionality: Adversity 
and Standing Issues,” courts have relied on AT&T when evaluating whether a congressional plaintiff has standing to 
initiate a lawsuit against the executive branch. See, e.g., Comm. on Oversight & Gov’t Reform v. Holder, 979 F. Supp. 
2d 1, 21 (D.D.C. 2013); Comm. on the Judiciary, U.S. House of Representatives v. Miers, 558 F. Supp. 2d 53, 71

with broader standing principles that a plaintiff may “designate agents to represent it in federal 
court” without running afoul of the standing requirement.232 
In this vein, courts have held that a house of Congress can authorize a committee to sue on its 
behalf. For example, in the District Court for the District of Columbia’s 2008 opinion in 
Committee on the Judiciary, U.S. House of Representatives v. Miers,233 the House Committee on 
the Judiciary filed suit in federal court to enforce a subpoena it had issued against certain 
executive officials.234 Critically, before the committee filed its lawsuit, the full House of 
Representatives passed a resolution authorizing the chairman of the committee “to initiate a civil 
action in federal court” to enforce the subpoena.235 The court therefore ultimately concluded “that 
the Committee ha[d] standing to enforce its duly issued subpoena through a civil suit.”236 
According to the court, the fact that the committee had “been expressly authorized by House 
Resolution to proceed on behalf of the House of Representatives as an institution” distinguished 
Miers from cases like Raines in which individual legislators had invalidly attempted to assert 
injuries to their respective institutions as a whole rather than to themselves personally.237 In other 
words, “the fact that the House ha[d] issued a subpoena and explicitly authorized th[e] suit” was 
“the key factor that move[d Miers] from the impermissible category of an individual plaintiff 
asserting an institutional injury . . . to the permissible category of an institutional plaintiff 
asserting an institutional injury.”238 Thus, the committee, acting on the full House’s behalf with 
the House’s imprimatur, could validly sue “to vindicate both its right to the information that [was] 
the subject of the subpoena and its institutional prerogative to compel compliance with its 
subpoenas.”239 
Where, by contrast, a legislative plaintiff has not obtained congressional authorization to 
represent his respective house via an authorizing vote, courts have typically determined that the 
plaintiff lacks standing to sue to enforce subpoenas or otherwise assert an informational injury to 
Congress as a whole. For instance, in Cummings v. Murphy, the Seven-Member Rule case 
discussed above,240 the court concluded that individual Members lacked standing to argue that 
they were, in fact, validly proceeding on behalf of the institution. As the court explained, 
“[i]ndividual Members of Congress generally do not have standing to vindicate the institutional 
interests of the house in which they serve”241 unless they have obtained affirmative authorization 
                                                 
established in AT & T I.”); Miers, 558 F. Supp. 2d at 71 (“The precedential value and force of AT & T I survive 
Raines.”). But see infra “When Authorization Is Insufficient for Standing.”

(concluding that House committee had standing to sue “to enforce a subpoena it issued to the Attorney General of the 
United States” in part because “the House of Representatives ha[d] specifically authorized the initiation of th[e] action 
to enforce the subpoena”). Cf. U.S. House of Representatives v. U.S. Dep’t of Commerce, 11 F. Supp. 2d 76, 86

do not gainsay that these Senate leaders are in some sense aggrieved by the Pennsylvania Supreme Court’s actions. But 
that grievance alone does not carry them over the standing bar. United States Supreme Court precedent is clear—a

from their respective chambers of Congress.242 The court opined that “requiring authorization 
protects Congress’ institutional concerns from the caprice of a restless minority of Members.”243 
Cummings thus demonstrates that “it is not simply enough” for individual legislators “to point to 
an informational injury arising from an unmet statutory demand to demonstrate standing;”244 
courts generally also “look to the presence of authorization as a necessary . . . factor in evaluating 
standing in cases that pit the Executive and Legislative Branches against each other.”245 
Significantly, at least one opinion suggests that to validly authorize a plaintiff to pursue litigation 
on an institution’s behalf, that institution must expressly authorize the plaintiff to bring that 
specific lawsuit prior to the commencement of that suit; a freestanding authorization to pursue 
litigation may not always suffice to confer standing. Namely, in Walker v. Cheney,246 the 
Comptroller General247 sought a court order requiring the Vice President to produce certain 
documents.248 To support his argument that he possessed congressional authorization—and thus 
standing—to pursue this lawsuit on Congress’s behalf, the Comptroller General invoked 31 
U.S.C. § 716(b)(2), which purports to authorize the Comptroller General to “bring a civil action 
in the district court of the United States for the District of Columbia to require the head of [an 
executive] agency to produce a record.”249 The court, however, rejected that argument, concluding 
that this “generalized allocation of enforcement power” did not suffice to establish “that the 
current Congress ha[d] authorized the Comptroller General to pursue a judicial resolution of the 
specific issues” in the case before the court.250 To support that conclusion, the court emphasized 
that no committee requested the documents or issued a subpoena requiring the Vice President to 
produce them.251 Thus, in spite of the aforementioned statutory language purporting to empower 
the Comptroller General to bring suit, the court determined that “neither House of Congress, and 
no congressional committee, ha[d] authorized the Comptroller General to pursue the requested 
information through [a] judicial proceeding.”252  
When Authorization Is Insufficient for Standing 
Even where a legislature as a whole has purported to authorize a particular plaintiff to file suit on 
its behalf, that plaintiff must still satisfy the various requirements of standing, including the 
                                                 
legislator suffers no Article III injury when alleged harm is borne equally by all members of the legislature.”). 
242 See 321 F. Supp. 3d at 105-06 (“[Cases in which courts have permitted individual legislators to sue] have arisen 
almost exclusively in the subpoena enforcement context and have involved circumstances in which the plaintiff was a 
congressional committee that was duly authorized to bring suit by House resolution. In those cases, courts have found

individual plaintiff asserting an institutional injury in Raines to the permissible category of an institutional plaintiff

requirements of concrete and particular injury as to that institution.253 To illustrate, whereas a 
legislative plaintiff acting pursuant to the authorization of its respective institution generally 
possesses standing to sue to redress concrete and particular informational injuries to that 
institution,254 even an entire legislative body proceeding under valid authorization will not have 
standing to assert abstract or nonparticular injuries.255 As an example of a putative injury in the 
latter category, courts have generally rejected the idea that legislatures have standing based on 
their duty to legislate to challenge allegedly illegal acts by the Executive.256 In Alaska Legislative 
Council v. Babbitt, for instance, the D.C. Circuit determined that the Alaska Legislative Council 
lacked standing to challenge federal management of subsistence taking of fish and wildlife on 
federal lands in Alaska.257 The council claimed that it was injured because individual Alaskan 
legislators had a “duty to legislate for the management of all the State’s resources” and the federal 
program interfered with this duty.258 Although the Alaska legislature had not explicitly voted to 
authorize the council to sue, the court assumed the plaintiff possessed such authorization because 
of its status as a “permanent interim committee and service agency of the legislature.”259 Despite 
this authorization, the court concluded that the committee lacked standing because its injuries did 
not belong to it, but rather, belonged to the “State itself,” and only the governor could bring that 
suit on behalf of Alaska.260 The legislature had thus failed to identify a “separate [and] 
identifiable” injury entitling it to sue.261 
Additionally, several courts have concluded that legislative plaintiffs lack standing to assert a 
generalized interest in the proper interpretation or application of a statute irrespective of whether 
the full legislative body has authorized the plaintiffs to sue. For instance, Newdow v. U.S. 
Congress involved a challenge brought by an individual plaintiff to the constitutionality of the 
Pledge of Allegiance’s use of the phrase “under God.”262 After the Ninth Circuit had issued a 
ruling allowing the case to proceed, the Senate moved to intervene in the case pursuant to a 
provision of the U.S. Code giving the Senate Legal Counsel the right to intervene unless the 
Senate would lack “standing to intervene under . . . [A]rticle III of the Constitution.”263 The court 
concluded that this language required it to examine the Senate’s putative interest in the case at 
                                                 
253 Cf. Ariz. State Legislature v. Ariz. Indep. Redistricting Comm’n, 135 S. Ct. 2652, 2665 (2015) (holding that state 
legislature’s alleged injury was not “too ‘conjectural’ or ‘hypothetical’ to establish standing”).

and the institutional diminution of its subpoena power.”).

legislators’ asserted injury was “nothing more than an ‘abstract dilution of institutional legislative power’” and was 
therefore insufficient to confer standing) (quoting Raines v. Byrd, 521 U.S. 811, 826 (1997)). 
256 See, e.g., id. at 1337-38 (rejecting argument that state legislators possessed standing in furtherance of their putative 
“affirmative duty to legislate for the management of all of the State’s resources”).

hand.264 The Ninth Circuit denied the Senate’s motion,265 concluding that the Senate lacked 
standing to defend the law’s constitutionality.266 The court explained that a “general desire to see 
the law enforced as written” did not suffice to give standing to a house of Congress to defend the 
law.267  
A more recent consideration of institutional standing occurred in the 2015 case of United States 
House of Representatives v. Burwell.268 In that case, the House of Representatives asserted two 
claims against various executive branch entities: (1) a constitutional claim that the defendants 
“spent billions of unappropriated dollars to support the Patient Protection and Affordable Care 
Act” (ACA) in violation of the Appropriations Clause of the U.S. Constitution;269 and (2) a 
statutory claim that the Secretary of the Treasury, “under the guise of implementing regulations,” 
had “effectively amended” certain aspects of the ACA “by delaying its effect and narrowing its 
scope.”270 The court concluded that the House possessed standing to pursue the constitutional 
claim but not the statutory claim.271 The court first determined that the House had standing to 
pursue its constitutional claim272 because “Congress (of which the House and Senate are equal) is 
the only body empowered by the Constitution to adopt laws directing monies to be spent from the 
U.S. Treasury,” and the Executive’s alleged circumvention of that structure was a sufficiently 
concrete and particularized injury as to the House as a whole.273 However, the district court then 
ruled that the House lacked standing to pursue its parallel challenges to the Executive’s alleged 
violation of the statutory scheme,274 reasoning that Article III does not create “general legislative 
standing” by which the branches of Congress may sue the Executive for any alleged violation of 
statutes or the Constitution by the Executive.275 Because the Executive’s alleged violation of the 
ACA would cause the House “no particular harm,” the House lacked standing to pursue its 
statutory claim.276 
Burwell also rejected the argument that separation-of-powers concerns required the dismissal of 
the House’s claims.277 In Arizona State Legislature, the Court had noted that such concerns might 
be significant in a dispute between Congress and the President,278 but the Burwell court dismissed 
such concerns as dicta and did not find them controlling.279 Instead, the court determined that the 
case presented a “plain dispute over a constitutional command” that the judiciary was well suited

to resolve.280 These separation-of-powers concerns, particularly as they relate to Congress’s 
interests with respect to the executive branch’s execution of a statutory scheme, play a 
particularly important role in answering the question of when Congress can intervene in litigation, 
as discussed below.281 
Congressional Intervention to Defend a Statute’s 
Constitutionality: Adversity and Standing Issues 
Whereas the analysis above focuses mainly on congressional entities filing their own lawsuits as 
plaintiffs, legislators or a legislature as a whole may also attempt to participate in ongoing 
litigation between nonlegislative parties in a variety of ways. The procedural rules governing the 
federal courts contemplate that, subject to specified conditions, a nonparty may “intervene” in an 
existing federal case.282 Generally, if a court permits an entity to intervene in a case, that entity 
becomes a full party to the litigation and may freely participate in the case to the same extent as 
the original parties.283 For instance, subject to certain exceptions and conditions, an intervenor 
may generally (among other things) file briefs and motions, participate in discovery, and appeal 
adverse judgments.284  
As relevant here, congressional litigants periodically attempt to intervene in existing federal cases 
initiated by noncongressional parties.285 As explained in the following subsections, whether such 
attempts ultimately succeed depends on a variety of factors that to a large degree mirror the 
considerations relevant to whether a legislative plaintiff may initiate new litigation in federal 
court.286 
Justiciability Issues Involved in Intervention 
One potentially key—albeit infrequent287—situation in which a congressional entity may attempt 
to intervene in an ongoing lawsuit is when the executive branch declines to defend the

constitutionality of a federal statute.288 For instance, the U.S. House of Representatives recently 
intervened in the case of Texas v. United States to defend the constitutionality of provisions of the 
Affordable Care Act after the executive branch declined to defend the law in its entirety.289 As 
explained below, at least two questions may arise when Congress (or a Member, committee, or 
house thereof) attempts to intervene to defend a statute’s validity: (1) whether the executive 
branch’s refusal to defend the statute renders the original parties insufficiently adverse to create a 
justiciable controversy; and (2) whether Congress possesses standing to intervene in the case.  
With regard to the first question, whenever a plaintiff sues the United States to invalidate a 
federal statute, and the United States does not dispute the plaintiff’s assertion that the statute is 
unconstitutional, the fact that none of the named litigants wishes to defend the statute’s validity 
creates a potential risk that the original parties are not truly adverse to each other.290 The Supreme 
Court has ruled that “the business of federal courts” is limited “to questions presented in an 
adversary context,” rather than lawsuits between friendly parties.291 Like standing, this 
“adversity” requirement is a justiciability doctrine that the Supreme Court has derived (at least in 
part) from Article III’s “case or controversy” language.292 The Supreme Court has held that where 
“both litigants desire precisely the same result” in a particular case, there is generally “no case or 
controversy within the meaning of [Article] III of the Constitution,” and a federal court 
accordingly lacks jurisdiction over the case.293 In addition to this constitutional foundation, the 
Supreme Court has recognized that the adversity requirement also has a prudential dimension.294 
In other words, “even when Article III permits the exercise of federal jurisdiction, prudential 
considerations” may sometimes counsel against adjudicating a lawsuit where the parties lack that 
“concrete adverseness which sharpens the presentation of issues upon which the court so largely 
depends for illumination of difficult constitutional questions.”295 
With respect to the second question, while the standing doctrine is generally concerned with 
whether a plaintiff is a proper party to a particular lawsuit, other putative parties who are not 
plaintiffs, but are seeking distinct judicial relief from a federal court—such as intervenor-
                                                 
different statutory provisions. In only five of those cases did either chamber step in to defend the federal law 
(sometimes as amicus, sometimes as intervenor).”).

approval to intervene in this litigation to defend the constitutionality of Section 3 of DOMA . . . BLAG has a 
cognizable interest in defending the enforceability of statutes the House has passed when the President declines to 
enforce them.”).

defendants or defendant-appellants—likewise need to demonstrate that they possess standing in 
order to obtain the relief sought.296 For example, in Diamond v. Charles, the Supreme Court 
concluded that an intervenor lacked standing to appeal an adverse judgment against the original 
defendant after that defendant declined to file an appeal of its own.297 Under Supreme Court 
precedent, as long as the existing parties to the case present a justiciable controversy on their 
own, an intervenor need not independently possess standing to participate in the lawsuit so long 
as the intervenor seeks the same judicial relief as one or more of the existing parties.298 To the 
extent an intervenor seeks “relief that is different from that which is sought by a party with 
standing,” however, that intervenor must independently “possess Article III standing to intervene” 
in the case.299  
The Supreme Court has periodically considered how the adversity and standing doctrines apply in 
the congressional intervention context and has ultimately concluded that cases in which the 
executive branch declines to defend a federal statute and Congress steps in to defend the law may 
potentially be justiciable.300 For instance, in Immigration and Naturalization Service (INS) v. 
Chadha, an alien challenged the constitutionality of a particular provision of the Immigration and 
Nationality Act that had authorized one house of Congress, by resolution, to invalidate the 
decisions of the executive branch.301 Because the INS agreed with the alien that this “one-house 
veto” provision was unconstitutional,302 the Court needed to examine whether the case presented 
“a genuine controversy” rather than a nonjusticiable “non-adversary[] proceeding” between two 
friendly parties.303 Crucially, however, both the Senate and the House had intervened in the case 
to defend the statute’s constitutionality.304 The Court therefore held that, because Congress was “a 
proper party to defend the constitutionality of” this statute, “the concrete adverseness” required 
by Article III existed “beyond doubt” “from the time of Congress’ formal intervention” in the 
case.305 Going further, the Court also explained in dicta that “there was adequate [Article] III 
                                                 
296 See Matthew L. Hall, Standing of Intervenor-Defendants in Public Law Litigation, 80 FORDHAM L. REV. 1539, 1541 
(2012) (“The doctrine of standing is generally understood to limit the ability of plaintiffs to seek relief in federal court  
. . . What has gone largely unnoticed . . . is the degree to which Article III restricts who may defend against a claim in 
federal court. This aspect of standing doctrine is so under-appreciated that some courts and scholars have even asserted, 
incorrectly, that Article III’s standing restrictions apply only to plaintiffs.”). See also Town of Chester, N.Y. v. Laroe

adverseness” in the case even “prior to Congress’ intervention” because the “INS would have 
deported” the alien against his wishes if the federal courts had rejected the alien’s constitutional 
challenge.306 In other words, because the INS would have enforced the challenged statute despite 
its unwillingness to defend the statute’s constitutionality in a judicial proceeding, the majority 
viewed the case as presenting a justiciable controversy between the INS and the alien even if 
Congress had never intervened.307 Although the Chadha Court also acknowledged that “there may 
be prudential, as opposed to [Article] III, concerns about sanctioning the adjudication of th[e] 
case in the absence of any participant supporting the validity of” the provision’s constitutionality, 
the Supreme Court explained that the lower court had “properly dispelled any such concerns by 
inviting and accepting briefs from both Houses of Congress.”308 The Court further opined that 
“Congress is the proper party to defend the validity of a statute when an agency of government, as 
a defendant charged with enforcing the statute, agrees with [the] plaintiffs that the statute is 
inapplicable or unconstitutional.”309 
Prior to the Supreme Court’s 2013 decision in United States v. Windsor, one might plausibly read 
Chadha to stand for the limited proposition that Congress may intervene to defend an undefended 
federal law (albeit one that the Executive has continued to enforce) only when the judicial 
invalidation of that law would directly affect Congress’s institutional powers, such as by 
eliminating Congress’s ability to validly utilize a one-house legislative veto.310 In Windsor, 
however, the Court appeared to implicitly adopt a broader conception of Chadha by permitting a 
congressional entity to intervene to defend an undefended law even though the statute at issue had 
no direct bearing on Congress’s institutional powers.311 The respondents in Windsor challenged 
the constitutionality of a provision of the Defense of Marriage Act (DOMA) on equal protection 
grounds.312 During the course of the litigation, however, “the Attorney General of the United 
States notified the Speaker of the House of Representatives . . . that the Department of Justice 
would no longer defend the constitutionality of” the challenged provision.313 Nevertheless, the 
Attorney General stated that he would continue to enforce the provision in order to “provid[e] 
Congress a full and fair opportunity to participate in the litigation” over the provision’s validity, 
and accordingly appealed the lower court’s judgment invalidating the statute to the Supreme 
Court.314 After the Attorney General announced that he would not defend the statute, the House’s

with destruction of what they claimed to be one of their institutional powers. The Executive choosing not to defend that 
power, we permitted the House and Senate to intervene. Nothing like that is present here.”). See also Matthew I. Hall, 
Making Sense of Legislative Standing, 90 S. CAL. L. REV. 1, 20 (2016) (“Chadha can be read either broadly—as

Bipartisan Legal Advisory Group (BLAG)—which is “composed of the Speaker and the majority 
and minority leaderships” of the House315—“voted to intervene in the litigation to defend the 
constitutionality of” the provision.316 The district court permitted BLAG to intervene.317  
Because “the Government largely agree[d] with the opposing part[ies] on the merits of the 
controversy,”318 the Supreme Court needed to determine whether the executive branch’s 
“concession that [the challenged provision was] unconstitutional” rendered the case 
nonjusticiable on adversity grounds.319 The Court first concluded that the case presented “a 
justiciable dispute as required by Article III” because (1) the executive branch had announced its 
“inten[tion] to enforce the challenged law” if the court ultimately deemed the provision 
constitutional;320 and (2) the lower court had “order[ed] the United States to pay money” to the 
challengers “that it would not disburse but for the court’s order.”321 The Court accordingly 
determined that “the United States retain[ed] a stake sufficient to support Article III jurisdiction 
on appeal and in proceedings before th[e] Court.”322  
The Court next concluded that the legislative branch’s presence in the case alleviated any purely 
prudential concerns posed by the executive branch’s refusal to defend the provision’s validity.323 
The Court explained that “BLAG’s sharp adversarial presentation of the issues satisfie[d] the 
prudential concerns that otherwise might counsel against hearing an appeal from a decision with 
which the principal parties agree.”324 Critically, because Windsor and the United States presented 
a justiciable controversy within the meaning of Article III on their own, the Court did not need to 
resolve whether BLAG would have independently possessed Article III standing to intervene in 
the case and defend the statute on its own authority.325 As explained in greater detail below, 
however, the Court also implied that it might have deemed the case nonjusticiable if the 
Executive had declined to enforce the challenged statute in addition to merely refusing to defend 
its constitutionality.326 
Chadha and Windsor thus stand for the propositions that (1) the Executive’s refusal to defend a 
statute will not always render the lawsuit challenging that statute nonjusticiable; and  
(2) congressional intervention in ongoing federal litigation does not necessarily raise Article III 
standing problems327—at least as long as Congress does not pursue additional relief beyond a

judgment in the United States’ favor.328 To that end, lower federal courts have frequently 
permitted legislative actors to intervene as defendants in cases where the executive branch agreed 
with the plaintiff that a challenged statute was unconstitutional.329  
Still, the federal courts’ Article III jurisdiction to adjudicate such cases may not be unlimited. 
Although Chadha and Windsor suggest that Congress may help alleviate prudential adversity 
problems created by the executive branch’s nondefense of a statute by intervening to defend the 
challenged law, neither case says anything definitive about whether a congressional intervenor 
would have independently possessed Article III standing in those cases, especially in cases where 
the Executive refuses to enforce the underlying statute.330 Because the Executive continued to 
enforce the challenged statutes in Chadha and Windsor despite its refusal to defend their 
constitutionality,331 the Court concluded that the “refusal of the Executive to provide the relief 
sought” by the plaintiff “suffice[d] to preserve a justiciable dispute as required by Article III”332 
regardless of whether or not Congress had intervened to mitigate any purely prudential obstacles 
to justiciability resulting from the Executive’s refusal to defend the law.333 In other words, 
because “the United States retains a stake sufficient to support Article III jurisdiction” when it 
continues to enforce a statute that it declines to defend in court, the existence of a justiciable 
controversy between the plaintiff and the United States relieved the congressional intervenors in 
Chadha and Windsor of the burden to independently demonstrate Article III standing of their own

before participating in the case.334 The Windsor Court expressly declined to decide, however, 
“whether BLAG would have standing to” defend DOMA “on BLAG’s own authority” if the 
Executive had also refused to enforce the statute in addition to merely refusing to defend it.335  
The dissenting Justices in Windsor—who disagreed with the majority on the issue of adversity 
and therefore had to reach the standing question—could not agree on whether and when a house 
of Congress possesses standing to defend an undefended statute.336 Justice Alito, for instance, 
reasoned that “in the narrow category of cases in which a court strikes down an Act of Congress 
and the Executive declines to defend the Act, Congress both has standing to defend the 
undefended statute and is a proper party to do so.”337 According to Justice Alito, “because 
legislating is Congress’ central function,” a judicial decision “striking down an Act of Congress” 
injures each chamber of Congress as an institution by “impair[ing] Congress’ legislative 
power.”338 By contrast, Justice Scalia, joined by Chief Justice Roberts and Justice Thomas, 
instead suggested that the legislative branch possesses standing to intervene in such lawsuits only 
when the case implicates “the validity of a mode of congressional action,” such as the one-house 
legislative veto challenged in Chadha.339 According to Justice Scalia, Congress may only “hale 
the Executive before the courts . . . to vindicate its own institutional powers to act,” not “to 
correct a perceived inadequacy in the execution of its laws”—which, in Justice Scalia’s view, 
does not constitute an institutional injury to Congress itself.340 As this exchange between the 
dissenting Justices in Windsor reflects, the circumstances under which Congress may permissibly 
intervene to defend the validity of a statute the Executive refuses to enforce remains an 
unanswered question, and the answer to that question will likely implicate the same sorts of 
policies and principles that animate the doctrines governing whether and when a plaintiff may sue 
to vindicate Congress’s institutional interests.341 
Other Relevant Considerations in Intervention 
In addition to the adversity and standing doctrines discussed above, other legal principles may 
also affect whether a congressional entity may permissibly intervene in a federal case to defend a 
statute’s constitutionality or for some other purpose. For one, just as a legislator ordinarily may 
not initiate a lawsuit without the affirmative consent of his or her respective house,342 a 
congressional entity typically cannot intervene in a preexisting federal case without first obtaining 
authorization to do so.343 Where congressional entities have first obtained authorization to

participate in an ongoing lawsuit from their respective houses, however, courts have typically 
allowed those entities to intervene.344 However, a congressional entity seeking to intervene in 
ongoing litigation must comply with all applicable statutory345 and procedural346 rules governing 
legislative intervention in federal court.347 
Participation as Amicus Curiae 
If Congress (or a unit or individual Member thereof) cannot participate as a full party to a 
particular lawsuit due to one or more of the constitutional, statutory, procedural, and prudential 
obstacles discussed above, it may still be able to participate in the case in a more limited capacity 
as an amicus curiae.348 An amicus curiae—a Latin term for “friend of the court”—is an entity 
with “a strong interest in the subject matter” of a particular case that may submit legal briefs or 
other filings to the court in support of (or against) a particular position,349 but may not otherwise 
participate in the suit to the same extent as an original party or an intervenor.350  
Members, houses, and committees of Congress have successfully filed amicus briefs in a wide 
variety of cases.351 To name just a few salient examples, after the executive branch declined to 
defend the validity of the independent counsel provision of the Ethics in Government Act, “both

Congress in th[e] action”).

passed H.Res. 1420, authorizing Chairman Moss’s intervention on behalf of the Committee and the House . . . Thus, we 
need not consider the standing of a single [M]ember of Congress to advocate his own interest in the congressional 
subpoena power. It is clear that the House as a whole has standing to assert its investigatory power, and can designate a 
member to act on its behalf.”). See also Windsor, 570 U.S. at 754 (noting that the district court “grant[ed] intervention 
by BLAG as an interested party” after BLAG “voted to intervene in the litigation to defend the constitutionality of § 3 
of DOMA”).

houses [of Congress] filed amicus briefs defending the legislation’s constitutionality.”352 
Similarly, two opposing coalitions of individual Members of Congress filed dueling amicus briefs 
in a Supreme Court case concerning the continued vitality of Roe v. Wade.353 
The procedural rules governing the submission of amicus briefs may vary from court to court.354 
Ultimately, however, federal courts possess broad discretion to decide whether to allow a 
nonparty to submit an amicus brief in a particular case.355 Thus, on rare occasions, some courts 
have exercised that discretion to reject congressional attempts to file amicus briefs.356 For 
instance, the U.S. Court of Federal Claims recently prohibited the House of Representatives from 
filing an amicus brief in a private party’s lawsuit against the United States.357 The court, noting 
that “the sole purpose of the House’s proposed amicus brief [was] to urge a ground for dismissing 
[the] plaintiff’s complaint that was not raised by the [Department of Justice] in its motion to 
dismiss,” reasoned that allowing the House to participate as an amicus would “improperly 
intrud[e] on the DOJ’s ‘exclusive and plenary’ authority to litigate the case on the United States’ 
behalf.”358  
Considerations for Congress 
As discussed, courts have identified several considerations that may be relevant when assessing 
whether a legislative entity has suffered a justiciable injury-in-fact359 allowing it to seek judicial 
relief from a federal court, including 
  the presence of congressional authorization;360

  availability of alternative plaintiffs to bring a judicial challenge;364 and 
  whether the lawsuit is an attempt to assert an interest other than the generalized 
interest in the proper application and implementation of the law.365 
While these considerations provide some guidance with regard to the standing inquiry in lawsuits 
involving a legislative entity, they do not comprehensively resolve every question that may arise. 
Additionally, the legal principles that courts have articulated in congressional standing cases to 
date are not always perfectly consistent with each other, making it difficult to predict whether any 
particular legislative attempt to participate in litigation will overcome the standing hurdle.366 
Further compounding that difficulty is the fact that there are very few cases analyzing the 
legislative standing doctrine and only a handful of rulings on the issue from the Supreme Court 
itself. As a consequence, it is important to identify areas of lingering doctrinal uncertainty,367 as 
well as measures that Members, committees, and houses of Congress may take to increase the 
likelihood that any given lawsuit will surmount the standing barrier.368

Areas of Doctrinal Uncertainty 
One of the key unanswered questions regarding legislative standing concerns what form of 
authorization is necessary to empower a legislative plaintiff to assert an institutional injury on 
behalf of his respective institution.369 In Raines v. Byrd, for instance, the Supreme Court 
concluded that the individual Member plaintiffs “ha[d] not been authorized to represent their 
respective Houses of Congress” for standing purposes370 even though Congress specifically 
enacted a statute purporting to authorize “any Member of Congress” to “bring an action . . . for 
declaratory judgment and injunctive relief on the ground that any provision of [the Line Item Veto 
Act] violates the Constitution.”371 Similarly, in Walker v. Cheney, the court concluded that 31 
U.S.C. § 716(b)(2)—which purports to grant the Comptroller General freestanding authority to 
“bring a civil action . . . to require the head of [an] agency to produce a record”372—nonetheless 
did not authorize the Comptroller General to sue the Vice President.373 While a congressional 
litigant that obtains express authorization from a full house of Congress to participate in a 
specifically identified lawsuit is more likely to satisfy the standing requirement than a litigant 
who does not,374 it remains uncertain whether a general statute or rule purporting to authorize an 
entity to proceed on Congress’s behalf would suffice to authorize that entity to proceed in court 
on behalf of Congress without a specific vote empowering that individual to represent Congress’s 
interests in a particular case. For instance, House Rule II(8)(b), promulgated by the 116th 
Congress, states that “unless otherwise provided by the House, [(BLAG)] speaks for, and 
articulates the institutional position of, the House in all litigation matters.”375 At least one 
Member of the 116th Congress has interpreted this language to mean that “a vote of the BLAG to 
authorize litigation . . . is the equivalent of a vote of the full House of Representatives” to initiate 
a lawsuit in federal court.376 In light of Walker’s holding that a “generalized allocation of . . . 
power” does not necessarily amount to authorization to litigate “specific issues” for the purposes 
of the standing doctrine, it is unclear whether (or to what extent) House Rule II(8)(b) supplies the 
necessary authorization for BLAG to represent the House’s interests in any particular case 
without a specific authorizing vote.377 
An additional open question that existing precedent does not conclusively resolve is whether and 
under what circumstances the general availability of blunt legislative remedies—such as 
                                                 
369 See supra “Institutional Standing.”

373 See 230 F. Supp. 2d 51, 69-70 (D.D.C. 2002) (“[31 U.S.C. § 716(b)(2)’s] highly generalized allocation of 
enforcement power to the Comptroller General twenty-two years ago hardly gives this Court confidence that the current 
Congress has authorized this Comptroller General to pursue a judicial resolution of the specific issues affecting the 
balance of power between the Article I and Article II Branches that have crystalized during the course of this dispute 
and lawsuit.”). 
374 The same judge that decided Walker, for instance, concluded in Miers that the House Committee on the Judiciary 
possessed standing to assert an institutional injury in part because in contrast to Walker, “the full House ha[d] 
specifically authorized filing [the] suit.” See Comm. on the Judiciary, U.S. House of Representatives v. Miers, 558 F. 
Supp. 2d 53, 70-71 (D.D.C. 2008).

impeachment—will deprive a legislative litigant of standing to seek judicial relief against the 
executive branch. In Campbell v. Clinton, for instance, the D.C. Circuit concluded that individual 
Members lacked standing to sue the President in part because “there always remains the 
possibility of impeachment should a President act in disregard of Congress’ authority.”378 In 
Blumenthal v. Trump, by contrast, the court concluded that a group of individual Members did 
have standing to sue the President, stating (with little explanation) that “the availability of the 
extreme measure of impeachment to enforce the President’s compliance with the [Emoluments] 
Clause is not an adequate remedy.”379 Further litigation will likely be necessary to resolve these 
conflicting strands of congressional standing precedent. 
Perhaps the most difficult open question raised by the legislative standing jurisprudence concerns 
what sort of institutional injury is sufficient to afford a legislative entity standing. At one end of 
the spectrum, courts have generally recognized that institutional plaintiffs may sue to remedy 
discrete injuries, such as informational injuries resulting from an executive branch agency’s 
refusal to comply with a subpoena.380 At the other end, courts have typically determined that even 
institutional plaintiffs cannot assert a generalized, nonparticularized interest in the proper 
application, interpretation, or enforcement of the law.381 Some recent cases from the district 
courts, however, appear to envision a broader conception of institutional injury.382 The court in 
U.S. House of Representatives v. Burwell, for example, concluded that the House possessed 
standing to pursue constitutional claims “that the Executive ha[d] drawn funds from the Treasury 
without a congressional appropriation.”383 Critical to the court’s holding was the fact that the 
Constitution designated “the Congress (of which the House and Senate are equal)” as “the only 
body empowered . . . to adopt laws directing monies to be spent from the U.S. Treasury.”384 
According to the court, the “constitutional structure would collapse, and the role of the House 
would be meaningless, if the Executive could circumvent the appropriations process and spend 
funds however it pleases.”385 Similarly, the Blumenthal v. Trump court concluded that the 
individual Member plaintiffs possessed standing in part because they did not merely “disagree 
with the manner in which the President [wa]s administering or enforcing the law,” but were 
instead wholly prevented from discharging their constitutionally designated role in the 
emoluments process.386 Burwell and Blumenthal thus suggest that Congress could have a

had extensive ‘self-help’ remedies available to pressure President Bush . . . Congressmen can certainly influence a 
President’s actions through the appropriations power, by, for example, attempting to deny funding . . . and as a last 
resort, Congress always has the option of impeachment.”).

justiciable injury when the executive branch violates the Constitution in a way that specifically 
undermines Congress’s authority in a particular governmental process.387 
It is unclear whether the Supreme Court or the federal appellate courts would ultimately endorse 
the broad conceptions of congressional standing that the Burwell and Blumenthal courts 
adopted.388 Because the parties in Burwell ultimately settled their dispute,389 neither the D.C. 
Circuit nor the Supreme Court ever determined whether the district court’s standing conclusions 
were correct.390 Nor has the D.C. Circuit resolved whether the district court correctly concluded 
that the plaintiffs in Blumenthal possess standing to pursue their Emoluments Clause 
challenges.391 Some (though not all)392 academics have argued, however, that the Burwell and 
Blumenthal courts’ expanded conception of standing may be unsound,393 As these decisions 
would appear to authorize congressional litigants to hale executive branch entities into the federal 
courts in a fairly broad array of factual circumstances that implicate separation-of-powers 
principles.394 Burwell, for instance, contains language suggesting that at least some congressional 
litigants possess standing to sue the executive branch whenever it spends unappropriated funds.395 
Blumenthal likewise contains language suggesting that legislative litigants—including individual 
Members—could very well possess standing to sue the President in a variety of contexts in which 
the Constitution offers Congress (or a house thereof) an opportunity to provide prior approval to a 
                                                 
387 See, e.g., Mank, supra note 335, at 189 (arguing that “U.S. House of Representatives v. Burwell appropriately found 
congressional standing to challenge President Obama’s alleged misuse of the appropriations process because a core 
institutional power of Congress was at stake”). 
388 See Nash, supra note 366, at 342 (stating that “the lower courts have . . . generally been more open to[] claims of 
congressional standing” than the Supreme Court).

nonetheless describing the court’s supposed “error” as “an understandable” one because “the Supreme Court’s 
legislative standing case law is far from crystalline”). 
394 See Hall, supra note 310, at 44 (arguing that “the district court’s theory of legislative standing” in Burwell “would 
undermine the Framers’ intentions and drag the federal courts into partisan wrangling between elected officials”);

a particular injury quite distinguishable from any suffered by the public generally . . . The House does have a 
continuing and direct interest in the appropriation process, for that is its role in our constitutional system and the source 
of virtually all of the House’s political power.”).

particular executive action,396 such as appointments.397 Future judicial decisions may provide 
further guidance on whether, how, and under what circumstances this sort of freestanding 
congressional authority to summon executive branch entities before a federal judge is consistent 
with the Supreme Court’s admonition that the “standing inquiry” is “especially rigorous when 
reaching the merits of the dispute would require [a court] to decide whether an action taken by 
one of the other two branches of the Federal Government was unconstitutional.”398  
What Can Congress (or a Member or Committee) Do? 
The fact that standing is a constitutional requirement circumscribes Congress’s ability to alter the 
aforementioned standing rules by enacting legislation. The Supreme Court has repeatedly 
reaffirmed “that Congress cannot erase Article III’s standing requirements by statutorily granting 
the right to sue to a plaintiff who would not otherwise have standing.”399 At the same time, 
however, the Court has also recognized “that Congress may ‘elevat[e] to the status of legally 
cognizable injuries concrete, de facto injuries that were previously inadequate in law.’”400 It is 
therefore possible that, even though Congress may not “abrogate the Art[icle] III minima,”401 
Congress may under presently undefined circumstances enact a statute that grants it standing to 
pursue a claim in federal court that it could not pursue in that statute’s absence. However, 
whether (and to what extent) Congress possesses such power to do so in the context of legislative 
standing may need to await further explication from the courts.402 
In the absence of such guidance from the judiciary, a congressional litigant’s best strategy may be 
to attempt to satisfy as many of the considerations listed above—that is, to 
  attempt to obtain authorization to pursue the specific lawsuit in question from 
one or both houses of Congress;403 
  attempt to persuade the court that all possible legislative remedies would be 
futile;404 
  argue that the allegedly unlawful action has deprived Members of Congress of 
the efficacy of their votes;405 
                                                 
396 See 335 F. Supp. 3d 45, 63 (D.D.C. 2018) (“Plaintiffs’ alleged injury is caused by the President’s alleged refusal to 
give them the opportunity to exercise their constitutional right to vote on whether to consent prior to his acceptance of 
prohibited foreign emoluments.”). 
397 See U.S. CONST. art. II, § 2, cl. 2 (providing that the President “shall appoint Ambassadors, other public Ministers 
and Consuls, Judges of the supreme Court, and all other Officers of the United States,” but only “by and with the 
Advice and Consent of the Senate”) (emphasis added).

effect (or does not go into effect), on the ground that their votes have been completely nullified.”).

  analogize to historical precedent in which courts entertained similar challenges 
by congressional litigants;406 
  demonstrate that no other litigant would possess standing to vindicate the 
congressional interest in dispute; and407 
  avoid framing the legal theory as a generalized grievance challenging the 
opposing party’s implementation or interpretation of a federal statute.408 
Nonetheless, as several scholars have emphasized, “not all interbranch disputes—even 
constitutional disputes—need to be resolved in the courts.”409 Indeed, the federal judiciary has in 
many cases expressed marked hesitance to interpose itself between dueling branches of the U.S. 
government.410 The lack of a judicial remedy to a congressional complaint may indicate that 
Congress’s most promising means for resolving disputes with the executive branch may be the 
political process, where a significant amount of constitutional decisionmaking occurs.411
