delivered the opinion of the Court.
Parents of black public school children allege in this nationwide class action that the Internal Revenue Service (IRS) has not adopted sufficient standards and procedures to fulfill its obligation to deny tax-exempt status to racially discriminatory private schools. They assert that the IRS thereby harms them directly and interferes with the ability of their *740children to receive an education in desegregated public schools. The issue before us is whether plaintiffs have standing to bring this suit. We hold that they do not.
I
The IRS denies tax-exempt status under §§ 501(a) and (c)(3) of the Internal Revenue Code, 26 U. S. C. §§ 501(a) and (c)(3) — and hence eligibility to receive charitable contributions deductible from income taxes under §§ 170(a)(1) and (c)(2) of the Code, 26 U. S. C. §§ 170(a)(1) and (c)(2) — to racially discriminatory private schools. Rev. Rui. 71-447, 1971-2 Cum. Bull. 230.1 The IRS policy requires that a school applying for tax-exempt status show that it “admits the students of any race to all the rights, privileges, programs, and activities generally accorded or made available to students at that school and that the school does not discriminate on the basis of race in administration of its educational policies, admissions policies, scholarship and loan programs, and athletic and other school-administered programs. ” Ibid. To carry out this policy, the IRS has established guidelines and procedures for determining whether a particular school is in fact racially nondiscriminatory. Rev. Proc. 75-50, 1975-2 Cum. Bull. 587.2 Failure to comply with the guidelines “will ordinarily result in the proposed revocation of” tax-exempt status. Id., §4.08, p. 589.
*741The guidelines provide that “[a] school must show affirmatively both that it has adopted a racially nondiscriminatory policy as to students that is made known to the general public and that since the adoption of that policy it has operated in a bona fide manner in accordance therewith.” Id., §2.02.3 The school must state its nondiscrimination policy in its organizational charter, id., §4.01, pp. 587-588, and in all of its brochures, catalogs, and other advertisements to prospective students, id., §4.02, p. 588. The school must make its nondiscrimination policy known to the entire community served by the school and must publicly disavow any contrary representations made on its behalf once it becomes aware of them. Id., §4.03.4 The school must have nondiscrimina*742tory policies concerning all programs and facilities, id., §4.04, p. 589, including scholarships and loans, id., §4.05,5 and the school must annually certify, under penalty of perjury, compliance with these requirements, id., §4.07.6
The IRS rules require a school applying for tax-exempt status to give a breakdown along racial lines of its student body and its faculty and administrative staff, id., §5.01-1, as well as of scholarships and loans awarded, id., §5.01-2. They also require the applicant school to state the year of its organization, id., §5.01-5, and to list “incorporators, founders, board members, and donors of land or buildings,” id., §5.01-3, and state whether any of the organizations among these have an objective of maintaining segregated public or private school education, id., §5.01-4. The rules further provide that, once given an exemption, a school must keep specified records to document the extent of compliance with the IRS guidelines. Id., §7, p. 590.7 Finally, the *743rules announce that any information concerning discrimination at a tax-exempt school is officially welcomed. Id., §6.8
In 1976 respondents challenged these guidelines and procedures in a suit filed in Federal District Court against the Secretary of the Treasury and the Commissioner of Internal Revenue.9 The plaintiffs named in the complaint are parents of black children who, at the time the complaint was filed, were attending public schools in seven States in school districts undergoing desegregation. They brought this nationwide class action “on behalf of themselves and their children, and ... on behalf of all other parents of black children attending public school systems undergoing, or which may in the future undergo, desegregation pursuant to court order [or] HEW regulations and guidelines, under state law, or voluntarily.” App. 22-23. They estimated that the class they seek to represent includes several million persons. Id., at 23.
Respondents allege in their complaint that many racially segregated private schools were created or expanded in their *744communities at the time the public schools were undergoing desegregation. Id., at 23-24. According to the complaint, many such private schools, including 17 schools or school systems identified by name in the complaint (perhaps some 30 schools in all), receive tax exemptions either directly or through the tax-exempt status of “umbrella” organizations that operate or support the schools. Id., at 23-38.10 Respondents allege that, despite the IRS policy of denying tax-exempt status to racially discriminatory private schools and despite the IRS guidelines and procedures for implementing that policy, some of the tax-exempt racially segregated private schools created or expanded in desegregating districts in fact have racially discriminatory policies. Id., at 17-18 (IRS permits “schools to receive tax exemptions merely on the basis of adopting and certifying — but not implementing — a policy of nondiscrimination”); id., at 25 (same).11 Respond*745ents allege that the IRS grant of tax exemptions to such racially discriminatory schools is unlawful.12
Respondents allege that the challenged Government conduct harms them in two ways. The challenged conduct
“(a) constitutes tangible federal financial aid and other support for racially segregated educational institutions, and
“(b) fosters and encourages the organization, operation and expansion of institutions providing racially segregated educational opportunities for white children avoiding attendance in desegregating public school districts and thereby interferes with the efforts of federal courts, HEW and local school authorities to desegregate public school districts which have been operating racially dual school systems.” Id., at 38-39.
*746Thus, respondents do not allege that their children have been the victims of discriminatory exclusion from the schools whose tax exemptions they challenge as unlawful. Indeed, they have not alleged at any stage of this litigation that their children have ever applied or would ever apply to any private school. See Wright v. Regan, 211 U. S. App. D. C. 281, 238, 656 F. 2d 820, 827 (1981) (“Plaintiffs . . . maintain they have no interest whatever in enrolling their children in a private school”). Rather, respondents claim a direct injury from the mere fact of the challenged Government conduct and, as indicated by the restriction of the plaintiff class to parents of children in desegregating school districts, injury to their children’s opportunity to receive a desegregated education.13 The latter injury is traceable to the IRS grant of tax exemptions to racially discriminatory schools, respondents allege, chiefly because contributions to such schools are deductible from income taxes under §§ 170(a)(1) and (c)(2) of the Internal Revenue Code and the “deductions facilitate the raising of funds to organize new schools and expand existing schools in order to accommodate white students avoiding attendance in desegregating public school districts.” App. 24.14
Respondents request only prospective relief. Id., at 40-41. They ask for a declaratory judgment that the challenged IRS tax-exemption practices are unlawful. They also *747ask for an injunction requiring the IRS to deny tax exemptions to a considerably broader class of private schools than the class of racially discriminatory private schools. Under the requested injunction, the IRS would have to deny tax-exempt status to all private schools
“which have insubstantial or nonexistent minority enrollments, which are located in or serve desegregating public school districts, and which either—
“(1) were established or expanded at or about the time the public school districts in which they are located or which they serve were desegregating;
“(2) have been determined in adversary judicial or administrative proceedings to be racially segregated; or
“(3) cannot demonstrate that they do not provide racially segregated educational opportunities for white children avoiding attendance in desegregating public school systems . . . Id., at 40.
Finally, respondents ask for an order directing the IRS to replace its 1975 guidelines with standards consistent with the requested injunction.
In May 1977 the District Court permitted intervention as a defendant by petitioner Allen, the head of one of the private school systems identified in the complaint. Id., at 54-55. Thereafter, progress in the lawsuit was stalled for several years. During this period, the IRS reviewed its challenged policies and proposed new Revenue Procedures to tighten requirements for eligibility for tax-exempt status for private schools. See 43 Fed. Reg. 37296 (1978); 44 Fed. Reg. 9451 (1979).15 In 1979, however, Congress blocked any strength*748ening of the IRS guidelines at least until October 1980.16 The District Court thereupon considered and granted the defendants’ motion to dismiss the complaint, concluding that respondents lack standing, that the judicial task proposed by respondents is inappropriately intrusive for a federal court, and that awarding the requested relief would be contrary to the will of Congress expressed in the 1979 ban on strengthening IRS guidelines. Wright v. Miller, 480 F. Supp. 790 (DC 1979).
The United States Court of Appeals for the District of Columbia Circuit reversed, concluding that respondents have standing to maintain this lawsuit. The court acknowledged that Simon v. Eastern Kentucky Welfare Rights Org., 426 U. S. 26 (1976), “suggests that litigation concerning tax liability is a matter between taxpayer and IRS, with the door *749barely ajar for third party challenges.” 211 U. S. App. D. C., at 239, 656 F. 2d, at 828. The court concluded, however, that the Simon case is inapposite because respondents claim no injury dependent on taxpayers’ actions: “[t]hey claim indifference as to the course private schools would take.” Id., at 240, 656 F. 2d, at 829.17 Instead, the court observed, “[t]he sole injury [respondents] claim is the denigration they suffer as black parents and schoolchildren when their government graces with tax-exempt status educational institutions in their communities that treat members of their race as persons of lesser worth.” Id., at 238, 656 F. 2d, at 827. The court held this denigration injury enough to give respondents standing since it was this injury which supported standing in Coit v. Green, 404 U. S. 997 (1971), summarily aff’g Green v. Connally, 330 F. Supp. 1150 (DC); Norwood v. Harrison, 413 U. S. 455 (1973); and Gilmore v. City of Montgomery, 417 U. S. 556 (1974). 211 U. S. App. D. C., at 239-243, 656 F. 2d, at 828-832. The Court of Appeals also held that the 1979 congressional actions were not intended to preclude judicial remedies and that the relief requested by respondents could be fashioned “without large scale judicial intervention in the administrative process,” id., at 248, 656 F. 2d, at 837.18 The court accordingly remanded the case to the District Court for further proceedings, enjoining the defendants meanwhile from granting tax-exempt status to any racially discriminatory school, App. 81-84.
*750The Government defendants and defendant-intervenor Allen filed separate petitions for a writ of certiorari in this Court. They both sought review of the Court of Appeals' holding that respondents have standing to bring this lawsuit. We granted certiorari, 462 U. S. 1130 (1983), and now reverse.

A
Article III of the Constitution confines the federal courts to adjudicating actual “cases” and “controversies.” As the Court explained in Valley Forge Christian College v. Americans United for Separation of Church and State, Inc., 454 U. S. 464, 471-476 (1982), the “case or controversy” requirement defines with respect to the Judicial Branch the idea of separation of powers on which the Federal Government is founded. The several doctrines that have grown up to elaborate that requirement are “founded in concern about the proper — and properly limited — role of the courts in a democratic society.” Warth v. Seldin, 422 U. S. 490, 498 (1975).
“All of the doctrines that cluster about Article III — not only standing but mootness, ripeness, political question, and the like — relate in part, and in different though overlapping ways, to an idea, which is more than an intuition but less than a rigorous and explicit theory, about the constitutional and prudential limits to the powers of an unelected, unrepresentative judiciary in our kind of government.” Vander Jagt v. O’Neill, 226 U. S. App. D. C. 14, 26-27, 699 F. 2d 1166, 1178-1179 (1983) (Bork, J., concurring).
The case-or-controversy doctrines state fundamental limits on federal judicial power in our system of government.
The Art. Ill doctrine that requires a litigant to have “standing” to invoke the power of a federal court is perhaps the most important of these doctrines. “In essence the question of standing is whether the litigant is entitled to have the *751court decide the merits of the dispute or of particular issues.” Warth v. Seldin, supra, at 498. Standing doctrine embraces several judicially self-imposed limits on the exercise of federal jurisdiction, such as the general prohibition on a litigant’s raising another person’s legal rights, the rule barring adjudication of generalized grievances more appropriately addressed in the representative branches, and the requirement that a plaintiff’s complaint fall within the zone of interests protected by the law invoked. See Valley Forge, supra, at 474-475. The requirement of standing, however, has a core component derived directly from the Constitution. A plaintiff must allege personal injury fairly traceable to the defendant’s allegedly unlawful conduct and likely to be redressed by the requested relief. 454 U. S., at 472.
Like the prudential component, the constitutional component of standing doctrine incorporates concepts concededly not susceptible of precise definition. The injury alleged must be, for example, “‘distinct and palpable,’” Gladstone, Realtors v. Village of Bellwood, 441 U. S. 91, 100 (1979) (quoting Warth v. Seldin, supra, at 501), and not “abstract” or “conjectural” or “hypothetical,” Los Angeles v. Lyons, 461 U. S. 95, 101-102 (1983); O’Shea v. Littleton, 414 U. S. 488, 494 (1974). The injury must be “fairly” traceable to the challenged action, and relief from the injury must be “likely” to follow from a favorable decision. See Simon v. Eastern Kentucky Welfare Rights Org., 426 U. S., at 38, 41. These terms cannot be defined so as to make application of the constitutional standing requirement a mechanical exercise.
The absence of precise definitions, however, as this Court’s extensive body of case law on standing illustrates, see generally Valley Forge, supra, at 471-476, hardly leaves courts at sea in applying the law of standing. Like most legal notions, the standing concepts have gained considerable definition from developing case law. In many cases the standing question can be answered chiefly by comparing the allegations of the particular complaint to those made in prior standing *752cases. See, e. g., Los Angeles v. Lyons, supra, at 102-105. More important, the law of Art. Ill standing is built on a single basic idea — the idea of separation of powers. It is this fact which makes possible the gradual clarification of the law through judicial application. Of course, both federal and state courts have long experience in applying and elaborating in numerous contexts the pervasive and fundamental notion of separation of powers.
Determining standing in a particular case may be facilitated by clarifying principles or even clear rules developed in prior cases. Typically, however, the standing inquiry requires careful judicial examination of a complaint’s allegations to ascertain whether the particular plaintiff is entitled to an adjudication of the particular claims asserted. Is the injury too abstract, or otherwise not appropriate, to be considered judicially cognizable? Is the line of causation between the illegal conduct and injury too attenuated? Is the prospect of obtaining relief from the injury as a result of a favorable ruling too speculative? These questions and any others relevant to the standing inquiry must be answered by reference to the Art. Ill notion that federal courts may exercise power only “in the last resort, and as a necessity,” Chicago & Grand Trunk R. Co. v. Wellman, 143 U. S. 339, 345 (1892), and only when adjudication is “consistent with a system of separated powers and [the dispute is one] traditionally thought to be capable of resolution through the judicial process,” Flast v. Cohen, 392 U. S. 83, 97 (1968). See Valley Forge, 454 U. S., at 472-473.
B
Respondents allege two injuries in their complaint to support their standing to bring this lawsuit. First, they say that they are harmed directly by the mere fact of Government financial aid to discriminatory private schools. Second, they say that the federal tax exemptions to racially discriminatory private schools in their communities impair *753their ability to have their public schools desegregated. See supra, at 745.
In the Court of Appeals, respondents apparently relied on the first injury. Thus, the court below asserted that “[t]he sole injury [respondents] claim is the denigration they suffer” as a result of the tax exemptions. 211 U. S. App. D. C., at 238, 656 F. 2d, at 827. In this Court, respondents have not focused on this claim of injury. Here they stress the effect of the tax exemptions on their “equal educational opportunities,” see, e. g., Brief for Respondents 12, 14, renewing reliance on the second injury described in their complaint.
Because respondents have not clearly disclaimed reliance on either of the injuries described in their complaint, we address both allegations of injury. We conclude that neither suffices to support respondents’ standing. The first fails under clear precedents of this Court because it does not constitute judicially cognizable injury. The second fails because the alleged injury is not fairly traceable to the assertedly unlawful conduct of the IRS.19
1
Respondents’ first claim of injury can be interpreted in two ways. It might be a claim simply to have the Government *754avoid the violation of law alleged in respondents’ complaint. Alternatively, it might be a claim of stigmatic injury, or denigration, suffered by all members of a racial group when the Government discriminates on the basis of race.20 Under neither interpretation is this claim of injury judicially cognizable.
This Court has repeatedly held that an asserted right to have the Government act in accordance with law is not sufficient, standing alone, to confer jurisdiction on a federal court. In Schlesinger v. Reservists Committee to Stop the War, 418 U. S. 208 (1974), for example, the Court rejected a claim of citizen standing to challenge Armed Forces Reserve commissions held by Members of Congress as violating the Incompatibility Clause of Art. I, § 6, of the Constitution. As citizens, the Court held, plaintiffs alleged nothing but “the abstract injury in nonobservance of the Constitution . . . .” Id., at 223, n. 13. More recently, in Valley Forge, supra, we rejected a claim of standing to challenge a Government conveyance of property to a religious institution. Insofar as the plaintiffs relied simply on “‘their shared individuated right’” to a Government that made no law respecting an establishment of religion, id., at 482 (quoting Americans United v. U. S. Dept. of HEW, 619 F. 2d 252, 261 (CA3 1980)), we held that plaintiffs had not alleged a judicially cognizable injury. “[Assertion of a right to a particular kind of Government conduct, which the Government has violated by acting differently, cannot alone satisfy the requirements of Art. Ill without draining those requirements of meaning.” 454 U. S., at 483. See also United States v. Richardson, 418 U. S. 166 (1974); Laird v. Tatum, 408 U. S. 1 (1972); *755Ex parte Lévitt, 302 U. S. 633 (1937). Respondents here have no standing to complain simply that their Government is violating the law.
Neither do they have standing to litigate their claims based on the stigmatizing injury often caused by racial discrimination. There can be no doubt that this sort of noneconomic injury is one of the most serious consequences of discriminatory government action and is sufficient in some circumstances to support standing. See Heckler v. Mathews, 465 U. S. 728, 739-740 (1984). Our cases make clear, however, that such injury accords a basis for standing only to “those persons who are personally denied equal treatment” by the challenged discriminatory conduct, ibid.
In Moose Lodge No. 107 v. Irvis, 407 U. S. 163 (1972), the Court held that the plaintiff had no standing to challenge a club’s racially discriminatory membership policies because he had never applied for membership. Id., at 166-167. In O’Shea v. Littleton, 414 U. S. 488 (1974), the Court held that the plaintiffs had no standing to challenge racial discrimination in the administration of their city’s criminal justice system because they had not alleged that they had been or would likely be subject to the challenged practices. The Court denied standing on similar facts in Rizzo v. Goode, 423 U. S. 362 (1976). In each of those cases, the plaintiffs alleged official racial discrimination comparable to that alleged by respondents here. Yet standing was denied in each case because the plaintiffs were not personally subject to the challenged discrimination. Insofar as their first claim of injury is concerned, respondents are in exactly the same position: unlike the appellee in Heckler v. Mathews, supra, at 740-741, n. 9, they do not allege a stigmatie injury suffered as a direct result of having personally been denied equal treatment.
The consequences of recognizing respondents’ standing on the basis of their first claim of injury illustrate why our cases plainly hold that such injury is not judicially cognizable. If the abstract stigmatie injury were cognizable, standing *756would extend nationwide to all members of the particular racial groups against which the Government was alleged to be discriminating by its grant of a tax exemption to a racially discriminatory school, regardless of the location of that school. All such persons could claim the same sort of abstract stigmatic injury respondents assert in their first claim of injury. A black person in Hawaii could challenge the grant of a tax exemption to a racially discriminatory school in Maine. Recognition of standing in such circumstances would transform the federal courts into “no more than a vehicle for the vindication of the value interests of concerned bystanders.” United States v. SCRAP, 412 U. S. 669, 687 (1973). Constitutional limits on the role of the federal courts preclude such a transformation.21
2
It is in their complaint’s second claim of injury that respondents allege harm to a concrete, personal interest that can support standing in some circumstances. The injury they identify — their children’s diminished ability to receive an education in a racially integrated school — is, beyond any doubt, not only judicially cognizable but, as shown by cases from Brown v. Board of Education, 347 U. S. 483 (1954), to Bob Jones University v. United States, 461 U. S. 574 (1983), one of the most serious injuries recognized in our legal system. Despite the constitutional importance of curing the *757injury alleged by respondents, however, the federal judiciary may not redress it unless standing requirements are met. In this case, respondents’ second claim of injury cannot support standing because the injury alleged is not fairly traceable to the Government conduct respondents challenge as unlawful.22
The illegal conduct challenged by respondents is the IRS’s grant of tax exemptions to some racially discriminatory schools. The line of causation between that conduct and desegregation of respondents’ schools is attenuated at best. From the perspective of the IRS, the injury to respondents is highly indirect and “results from the independent action of some third party not before the court,” Simon v. Eastern Kentucky Welfare Rights Org., 426 U. S., at 42. As the Court pointed out in Warth v. Seldin, 422 U. S., at 505, “the *758indirectness of the injury . . . may make it substantially more difficult to meet the minimum requirement of Art. Ill...
The diminished ability of respondents’ children to receive a desegregated education would be fairly traceable to unlawful IRS grants of tax exemptions only if there were enough racially discriminatory private schools receiving tax exemptions in respondents’ communities for withdrawal of those exemptions to make an appreciable difference in public school integration. Respondents have made no such allegation. It is, first, uncertain how many racially discriminatory private schools are in fact receiving tax exemptions.23 Moreover, it is entirely speculative, as respondents themselves conceded in the Court of Appeals, see n. 17, supra, whether withdrawal of a tax exemption from any particular school would lead the school to change its policies. See 480 F. Supp., at 796. It is just as speculative whether any given parent of a child attending such a private school would decide to transfer the child to public school as a result of any changes in educational or financial policy made by the private school once it was threatened with loss of tax-exempt status. It is also pure speculation whether, in a particular community, a large enough number of the numerous relevant school officials and parents would reach decisions that collectively would have a significant impact on the racial composition of the public schools.
*759The links in the chain of causation between the challenged Government conduct and the asserted injury are far too weak for the chain as a whole to sustain respondents’ standing. In Simon v. Eastern Kentucky Welfare Rights Org., supra, the Court held that standing to challenge a Government grant of a tax exemption to hospitals could not be founded on the asserted connection between the grant of tax-exempt status and the hospitals’ policy concerning the provision of medical services to indigents.24 The causal connection depended on the decisions hospitals would make in response to withdrawal of tax-exempt status, and those decisions were sufficiently uncertain to break the chain of causation between the plaintiffs’ injury and the challenged Government action. Id., at 40-46. See also Warth v. Seldin, supra. The chain of causation is even weaker in this case. It involves numerous third parties (officials of racially discriminatory schools receiving tax exemptions and the parents of children attending such schools) who may not even exist in respondents’ communities and whose independent decisions may not collectively have a significant effect on the ability of public school students to receive a desegregated education.
The idea of separation of powers that underlies standing doctrine explains why our cases preclude the conclusion that respondents’ alleged injury “fairly can be traced to the challenged action” of the IRS. Simon v. Eastern Kentucky Welfare Rights Org., supra, at 41. That conclusion would pave the way generally for suits challenging, not specifically identifiable Government violations of law, but the particular programs agencies establish to carry out their legal obligations. Such suits, even when premised on allegations of *760several instances of violations of law, are rarely if ever appropriate for federal-court adjudication.
“Carried to its logical end, [respondents’] approach would have the federal courts as virtually continuing monitors of the wisdom and soundness of Executive action; such a role is appropriate for the Congress acting through its committees and the ‘power of the purse’; it is not the role of the judiciary, absent actual present or immediately threatened injury resulting from unlawful governmental action.” Laird v. Tatum, 408 U. S., at 15.
See also Gilligan v. Morgan, 413 U. S. 1, 14 (1973) (Blackmun, J., concurring).
The same concern for the proper role of the federal courts is reflected in cases like O’Shea v. Littleton, 414 U. S. 488 (1974), Rizzo v. Goode, 423 U. S. 362 (1976), and Los Angeles v. Lyons, 461 U. S. 95 (1983). In all three cases plaintiffs sought injunctive relief directed at certain systemwide law enforcement practices.25 The Court held in each case that, absent an allegation of a specific threat of being subject to the challenged practices, plaintiffs had no standing to ask for an injunction. Animating this Court’s holdings was the principle that “[a] federal court ... is not the proper forum to .press” general complaints about the way in which government goes about its business. Id., at 112.
Case-or-controversy considerations, the Court observed in O’Shea v. Littleton, supra, at 499, “obviously shade into those determining whether the complaint states a sound basis for equitable relief.” The latter set of considerations should therefore inform our judgment about whether respondents *761have standing. Most relevant to this case is the principle articulated in Rizzo v. Goode, supra, at 378-379:
“When a plaintiff seeks to enjoin the activity of a government agency, even within a unitary court system, his case must contend with ‘the well-established rule that the Government has traditionally been granted the widest latitude in the “dispatch of its own internal affairs,” Cafeteria Workers v. McElroy, 367 U. S. 886, 896 (1961),’ quoted in Sampson v. Murray, 415 U. S. 61, 83 (1974).”
When transported into the Art. Ill context, that principle, grounded as it is in the idea of separation of powers, counsels against recognizing standing in a case brought, not to enforce specific legal obligations whose violation works a direct harm, but to seek a restructuring of the apparatus established by the Executive Branch to fulfill its legal duties. The Constitution, after all, assigns to the Executive Branch, and not to the Judicial Branch, the duty to “take Care that the Laws be faithfully executed.” U. S. Const., Art. II, §3. We could not recognize respondents’ standing in this case without running afoul of that structural principle.26
C
The Court of Appeals relied for its contrary conclusion on Gilmore v. City of Montgomery, 417 U. S. 556 (1974), on Norwood v. Harrison, 413 U. S. 455 (1973), and on Coit v. Green, 404 U. S. 997 (1971), summarily aff’g Green v. Con-*762nally, 330 F. Supp. 1150 (DC). Respondents in this Court, though stressing a different injury from the one emphasized by the Court of Appeals, see supra, at 752-753, place principal reliance on those cases as well. None of the cases, however, requires that we find standing in this lawsuit.
In Gilmore v. City of Montgomery, supra, the plaintiffs asserted a constitutional right, recognized in an outstanding injunction, to use the city’s public parks on a nondiscriminatory basis. They alleged that the city was violating that equal protection right by permitting racially discriminatory private schools and other groups to use the public parks. The Court recognized plaintiffs’ standing to challenge this city policy insofar as the policy permitted the exclusive use of the parks by racially discriminatory private schools: the plaintiffs had alleged direct cognizable injury to their right to nondiscriminatory access to the public parks. Id., at 570-571, n. 10.27
Standing in Gilmore thus rested on an allegation of direct deprivation of a right to equal use of the parks. Like the plaintiff in Heckler v. Mathews — indeed, like the plaintiffs having standing in virtually any equal protection case — the plaintiffs in Gilmore alleged that they were personally being denied equal treatment. 465 U. S., at 740-741, n. 9. The Gilmore Court did not rest its finding of standing on an abstract denigration injury, and no problem of attenuated causation attended the plaintiffs’ claim of injury.28
*763In Norwood v. Harrison, supra, parents of public school children in Tunica County, Miss., filed a statewide class action challenging the State’s provision of textbooks to students attending racially discriminatory private schools in the State. The Court held the State’s practice unconstitutional because it breached “the State’s acknowledged duty to establish a unitary school system,” id., at 460-461. See id., at 463-468. The Court did not expressly address the basis for the plaintiffs’ standing.
In Gilmore, however, the Court identified the basis for standing in Norwood: “The plaintiffs in Norwood were parties to a school desegregation order and the relief they sought was directly related to the concrete injury they suffered.” 417 U. S., at 571, n. 10. Through the school-desegregation decree, the plaintiffs had acquired a right to have the State “steer clear” of any perpetuation of the racially dual school system that it had once sponsored. 413 U. S., at 467. The interest acquired was judicially cognizable because it was a personal interest, created by law, in having the State refrain from taking specific actions. Cf. Warth v. Seldin, 422 U. S., at 500 (standing may exist by virtue of legal rights created by statute). The plaintiffs’ complaint alleged that the State directly injured that interest by aiding racially discriminatory private schools. Respondents in this lawsuit, of course, have no injunctive rights against the IRS that are allegedly being harmed by the challenged IRS action.
Unlike Gilmore and Norwood, Coit v. Green, supra, cannot easily be seen to have based standing on an injury different in kind from any asserted by respondents here. The plaintiffs *764in Coit, parents of black schoolchildren in Mississippi, sued to enjoin the IRS grant of tax exemptions to racially discriminatory private schools in the State. Nevertheless, Coit in no way mandates the conclusion that respondents have standing.
First, the decision has little weight as a precedent on the law of standing. This Court's decision in Coit was merely a summary affirmance; for that reason alone it could hardly establish principles contrary to those set out in opinions issued after full briefing and argument. See Fusari v. Steinberg, 419 U. S. 379, 392 (1975) (Burger, C. J., concurring); see also Tully v. Griffin, Inc., 429 U. S. 68, 74 (1976). Moreover, when the case reached this Court, the plaintiffs and the IRS were no longer adverse parties; and the ruling that was summarily affirmed, Green v. Connolly, 330 F. Supp. 1150 (DC 1971), did not include a ruling on the issue of standing, which had been briefly considered in a prior ruling of the District Court, Green v. Kennedy, 309 F. Supp. 1127, 1132 (DC), appeal dism’d sub nom. Cannon v. Green, 398 U. S. 956 (1970). Thus, “the Court’s affirmance in Green lacks the precedential weight of a case involving a truly adversary controversy.” Bob Jones University v. Simon, 416 U. S. 725, 740, n. 11 (1974).
In any event, the facts in the Coit case are sufficiently different from those presented in this lawsuit that the absence of standing here is unaffected by the possible propriety of standing there. In particular, the suit in Coit was limited to the public schools of one State. Moreover, the District Court found, based on extensive evidence before it as well as on the findings in Coffey v. State Educational Finance Comm’n, 296 F. Supp. 1389 (SD Miss.1969), that large numbers of segregated private schools had been established in the State for the purpose of avoiding a unitary public school system, 309 F. Supp., at 1133-1134; that the tax exemptions were critically important to the ability of such schools to succeed, id., at 1134-1136; and that the connection between *765the grant of tax exemptions to discriminatory schools and desegregation of the public schools in the particular State was close enough to warrant the conclusion that irreparable injury to the interest in desegregated education was threatened if the tax exemptions continued, id., at 1138-1139.29 What made possible those findings was the fact that, when the Mississippi plaintiffs filed their suit, the IRS had a policy of granting tax exemptions to racially discriminatory private schools; thus, the suit was initially brought, not simply to reform Executive Branch enforcement procedures, but to challenge a fundamental IRS policy decision, which affected numerous identifiable schools in the State of Mississippi. See id., at 1130.30
The limited setting, the history of school desegregation in Mississippi at the time of the Coit litigation, the nature of the IRS conduct challenged at the outset of the litigation, and the District Court’s particular findings, which were never challenged as clearly erroneous, see Motion to Dismiss or Affirm in Coit v. Green, O. T. 1971, No. 71-425, p. 13, amply distinguish the Coit case from respondents’ lawsuit. Thus, we *766need not consider whether standing was properly found to exist in Coit. Whatever the answer to that question, respondents’ complaint, which aims at nationwide relief and does not challenge particular identified unlawful IRS actions, alleges no connection between the asserted desegregation injury and the challenged IRS conduct direct enough to overcome the substantial separation of powers barriers to a suit seeking an injunction to reform administrative procedures.

“The necessity that the plaintiff who seeks to invoke judicial power stand to profit in some personal interest remains an Art. Ill requirement.” Simon v. Eastern Kentucky Welfare Rights Org., 426 U. S., at 39. Respondents have not met this fundamental requirement. The judgment of the Court of Appeals is accordingly reversed, and the injunction issued by that court is vacated.
It is so ordered.
Justice Marshall took no part in the decision of these cases.
As the Court explained last Term in Bob Jones University v. United States, 461 U. S. 574, 579 (1983), the IRS announced this policy in 1970 and formally adopted it in 1971. Rev. Rul. 71-447, 1971-2 Cum. Bull. 230. This change in prior policy was prompted by litigation over tax exemptions for racially discriminatory private schools in the State of Mississippi, litigation that resulted in the entry of an injunction against the IRS largely if not entirely coextensive with the position the IRS had voluntarily adopted. Green v. Kennedy, 309 F. Supp. 1127 (DC) (entering preliminary injunction), appeal dism’d sub nom. Cannon v. Green, 398 U. S. 956 (1970); Green v. Connally, 330 F. Supp. 1150 (DC) (entering permanent injunction), summarily aff’d sub nom. Coit v. Green, 404 U. S. 997 (1971).
The 1975 guidelines replaced guidelines issued for the same purpose in 1972. Rev. Proc. 72-54, 1972-2 Cum. Bull. 834.
The definition of “racially nondiscriminatory policy” is qualified in one respect: “A policy of a school that favors racial minority groups with respect to admissions, facilities and programs, and financial assistance will not constitute discrimination on the basis of race when the purpose and effect is to promote the establishment and maintenance of that school’s racially nondiscriminatory policy as to students.” Rev. Proc. 75-50, §3.02, 1975-2 Cum. Bull. 587.
One way a school can satisfy the publication requirement is to disseminate notice of the nondiscrimination policy through the print or broadcast media. Id., §4.03-1, p. 588. Detailed IRS rules govern what print and broadcast media may be selected as well as the content of the notice. Ibid. Although the IRS encourages all schools to follow that route, see id., § 4.03-2, p. 589, there are three alternative ways to satisfy the publication requirement.
First, a parochial or church-related school at least 75% of whose students in the preceding three years were members of the church satisfies the requirement if it gives notice of its nondiscrimination policy in church publications, unless it advertises in newspapers of general circulation. Id., §4.03-2(a), p. 588. Second, a school that draws its students from areas larger than the local community satisfies the requirement if it enrolls minority students in meaningful numbers or engages in promotional and recruitment activities reasonably designed to reach all racial segments of the areas from which students are drawn. Id., §4.03-2(b). Third, a school serving only a local community satisfies the publication requirement if it actually enrolls minority students in meaningful numbers. Id., §4.03-2(c), pp. 588-589. A school choosing any of these three options *742“must be prepared to demonstrate” on audit that this choice was justified. Id., §4.03-2, p. 589.
Scholarships and loans must generally be available without regard to race, and this fact must be known in the community served by the school. An exception is made, however, consistent with § 3.02 of Rev. Proc. 75-50, 1975-2 Cum. Bull. 587, see n. 3, supra, for financial assistance programs favoring minority students that are designed to promote the school’s nondiscriminatory policy. A second exception is made for financial assistance programs “favoring members of one or more racial groups that do not significantly derogate from the school’s racially nondiscriminatory policy . . . .” Rev. Proc. 75-50, §4.05, 1975-2 Cum. Bull. 589.
The regulations also declare that discrimination in the employment of faculty and administrative staff (or its absence) is indicative of discrimination with respect to students (or its absence). Id., §4.07.
Records must be kept, and preserved for three years, concerning the racial composition of the student body, the faculty and administrative staff, and the group of students receiving financial assistance. Copies of brochures, catalogs, and advertising must also be kept. Id., § 7.01, p. 590. Although the method of figuring racial composition must be described in the records compiled by the school, the school need not require students, applicants, or staff to furnish information not otherwise required, and the school generally need not release personally identifiable records. Id., *743§ 7.02. Cf. id., § 5.02, pp. 589-590 (information furnished by applicant for tax-exempt status subject to similar qualifications). Reports containing the required information, if filed in accordance with law with a Government agency, may satisfy the recordkeeping requirement if the information is current and the school maintains copies of the reports. Id., § 7.03, p. 590. Failure to maintain the required records gives rise to a presumption of noncompliance with the guidelines. Id., § 7.04.
The Revenue Procedure expressly notes, id., § 8, that its provisions are superseded by, to the extent they differ from, the injunction concerning Mississippi schools issued in Green v. Connolly, 330 F. Supp. 1150 (DC), summarily aff’d sub nom. Coit v. Green, 404 U. S. 997 (1971).
Shortly before respondents filed this action, the plaintiffs in the Green litigation, concerning the tax-exempt status of private schools in Mississippi, ibid., moved to reopen that suit, making allegations comparable to those in respondents’ complaint. See Wright v. Regan, 211 U. S. App. D. C. 231, 236, 656 F. 2d 820, 825 (1981). In 1977, the Mississippi litigation was consolidated with this suit. Ibid. The Green litigation was not consolidated with this lawsuit on appeal, however, and it is not before this Court.
Hereafter, references to a private school’s tax exemption embrace both tax-exempt status of the school and tax-exempt status of an “umbrella” organization. We assume, without deciding, that a grant of tax-exempt status to an “umbrella” organization of the sort respondents have in mind is subject to the same legal constraints as a grant of tax-exempt status directly to a school.
The complaint generally uses the phrase “racially segregated school” to mean simply that no or few minority students attend the school, irrespective of the school’s maintenance of racially discriminatory policies or practices. Although the complaint, on its face, alleges that granting tax-exempt status to any “racially segregated” school in a desegregating public school district is unlawful, App. 39, it is clear that respondents premise their allegation of illegality on discrimination, not on segregation alone.
The nub of respondents’ complaint is that current IRS guidelines and procedures are inadequate to detect false certifications of nondiscrimination policies. See Id., at 17-18, 25. This allegation would be superfluous if respondents were claiming that racial segregation even without racial discrimination made the grant of tax-exempt status unlawful. Moreover, respondents have noticeably refrained from asserting that the IRS violates the law when it grants a tax exemption to a nondiscriminatory private school that happens to have few minority students. Indeed, respondents’ brief in this Court makes a point of noting that their complaint alleges not only segregation but discrimination, see Brief for Respondents 10, n. 8, *745and it repeatedly states that the challenged Government conduct is the granting of tax exemptions to racially discriminatory private schools, see, e. g., id., at 9-10 (“Respondents alleged that the federal petitioners are continuing to grant tax-exempt status to racially discriminatory private schools . . .”); id., at 13-14.
Since respondents’ entire argument is built on the assertion that their rights are violated by IRS grants of tax-exempt status to some number of unidentified racially discriminatory private schools in desegregating districts, we resolve the ambiguity in respondents’ complaint by reading it as making that assertion.
Contrary to Justice Brennan’s statement, post, at 768, the complaint does not allege that each desegregating district in which they reside contains one or more racially discriminatory private schools unlawfully receiving a tax exemption.
The complaint alleges that the challenged IRS conduct violates several laws: § 501(c)(3) of the Internal Revenue Code, 26 U. S. C. § 501(c)(3); Title VI of the Civil Rights Act of 1964, 78 Stat. 252, as amended, 42 U. S. C. §2000d et seq.; Rev. Stat. §1977, 42 U. S. C. §1981; and the Fifth and Fourteenth Amendments to the United States Constitution.
Last Term, in Bob Jones University v. United States, 461 U. S. 574 (1983), the Court concluded that racially discriminatory private schools do not qualify for a tax exemption under § 501(c)(3) of the Internal Revenue Code.
Respondents did not allege in their 1976 complaint that their children were currently attending racially segregated schools. In 1979, during argument before the District Court, counsel for respondents stated that his clients’ children “do go to desegregated schools . . . App. 62.
Several additional tax benefits accrue to an organization receiving a tax exemption under § 501(c)(3) of the Code. Such an organization is exempt not only from income taxes but also from federal social security taxes, 26 U. S. C. § 3121(b)(8)(B), and from federal unemployment taxes, 26 U. S. C. § 3306(c)(8). Moreover, contributions to the organization are deductible not only from income taxes, 26 U. S. C. §§ 170(a)(1) and (c)(2), but also from federal estate taxes, 26 U. S. C. § 2055(a)(2), and from federal gift taxes, 26 U. S. C. § 2522(a)(2).
The first proposal was made on August 22,1978. 43 Fed. Reg. 37296. It placed the burden of proving good faith operation on a nondiscriminatory basis, evaluated according to specified factors, on any private school that had an insignificant number of minority students and that had been formed or substantially expanded at a time the public schools in its community were undergoing desegregation. The second proposal was made *748on February 18, 1979, after public comment and hearings. 44 Fed. Reg. 9451. It afforded private schools “greater flexibility” in proving nondiscriminatory operation, permitting satisfaction of this proof requirement by a showing that the school has “undertaken actions or programs reasonably designed to attract minority students on a continuing basis.” Id., at 9452, 9454.
Treasury, Postal Service, and General Government Appropriations Act of 1980, §§ 103 and 615, 93 Stat. 562, 577. Section 615 of the Act, known as the Dornan Amendment, specifically forbade the use of funds to carry out the IRS’s proposed Revenue Procedures. Section 103 of the Act, known as the Ashbrook Amendment, more generally forbade the use of funds to make the requirements for tax-exempt status of private schools more stringent than those in effect prior to the IRS’s proposal of its new Revenue Procedures.
These provisions expired on October 1, 1980, but Congress maintained its interest in IRS policies regarding tax exemptions for racially discriminatory private schools. The Dornan and Ashbrook Amendments were reinstated for the period December 16,1980, through September 30,1981. H. J. Res. 644, Pub. L. 96-536, §§ 101(a)(1) and (4), 94 Stat. 3166, as amended by Supplemental Appropriations and Rescission Act of 1981, § 401, 95 Stat. 95. For fiscal year 1982, Congress specifically denied funding for carrying out not only administrative actions but also court orders entered after the date of the IRS’s proposal of its first revised Revenue Procedure. H. J. Res. 325, Pub. L. 97-51, § 101(a)(3), 95 Stat. 958. No such spending restrictions are currently in force.
Indeed, the Court of Appeals observed that respondents “do not dispute that it is ‘speculative,’ within the Eastern Kentucky frame, whether any private school would welcome blacks in order to retain tax exemption or would relinquish exemption to retain current practices.” 211 U. S. App. D. C., at 240, 656 F. 2d, at 829 (footnotes omitted).
Judge Tamm dissented from the holding of the Court of Appeals. He concluded that standing in the three eases relied on by the majority was based on injury to rights under a court decree and that respondents in this ease asserted nothing more than the abstract interest in securing enforcement of the law against the Government. Id., at 249-259, 656 F. 2d, at 838-848.
The “fairly traceable” and “redressability” components of the constitutional standing inquiry were initially articulated by this Court as “two facets of a single causation requirement.” C. Wright, Law of Federal Courts § 13, p. 68, n. 43 (4th ed. 1983). To the extent there is a difference, it is that the former examines the causal connection between the assertedly unlawful conduct and the alleged injury, whereas the latter examines the causal connection between the alleged injury and the judicial relief requested. Cases such as this, in which the relief requested goes well beyond the violation of law alleged, illustrate why it is important to keep the inquiries separate if the “redressability” component is to focus on the requested relief. Even if the relief respondents request might have a substantial effect on the desegregation of public schools, whatever deficiencies exist in the opportunities for desegregated education for respondents’ children might not be traceable to IRS violations of law — grants of tax exemptions to racially discriminatory schools in respondents’ communities.
We assume, arguendo, that the asserted stigmatic injury may be caused by the Government’s grant of tax exemptions to racially discriminatory schools even if the Government is granting those exemptions without knowing or believing that the schools in fact discriminate. That is, we assume, without deciding, that the challenged Government tax exemptions are the equivalent of Government discrimination.
Cf. Valley Forge Christian College v. Americans United for Separation of Church and State, Inc., 454 U. S. 464, 489-490, n. 26 (1982) (citations omitted): “Were we to recognize standing premised on an ‘injury’ consisting solely of an alleged violation of a ‘ “personal constitutional right” to a government that does not establish religion,’ a principled consistency would dictate recognition of respondents’ standing to challenge execution of every capital sentence on the basis of a personal right to a government that does not impose cruel and unusual punishment, or standing to challenge every affirmative-action program on the basis of a personal right to a government that does not deny equal protection of the laws, to choose but two among as many possible examples as there are commands in the Constitution.”
Respondents’ stigmatic injury, though not sufficient for standing in the abstract form in which their complaint asserts it, is judicially cognizable to the extent that respondents are personally subject to discriminatory treatment. See Heckler v. Mathews, 465 U. S. 728, 739-740 (1984). The stigmatic injury thus requires identification of some concrete interest with respect to which respondents are personally subject to discriminatory treatment. That interest must independently satisfy the causation requirement of standing doctrine.
In Heckler v. Mathews, for example, the named plaintiff (appellee) was being denied monetary benefits allegedly on a discriminatory basis. We specifically pointed out that the causation component of standing doctrine was satisfied with respect to the claimed benefits. In distinguishing the case from Simon v. Eastern Kentucky Welfare Rights Org., 426 U. S. 26 (1976), we said: “there can be no doubt about the direct causal relationship between the Government’s alleged deprivation of appellee’s right to equal protection and the personal injury appellee has suffered — denial of Social Security benefits solely on the basis of his gender.” 465 U. S., at 741, n. 9.
In this litigation, respondents identify only one interest that they allege is being discriminatorily impaired — their interest in desegregated public school education. Respondents’ asserted stigmatic injury, therefore, is sufficient to support their standing in this litigation only if their school-desegregation injury independently meets the causation requirement of standing doctrine.
Indeed, contrary to the suggestion of Justice Brennan’s dissent, post, at 774-775, and n. 5, of the schools identified in respondents’ complaint, none of those alleged to be directly receiving a tax exemption is alleged to be racially discriminatory, and only four schools — Delta Christian Academy and Tallulah Academy in Madison Parish, La.; River Oaks School in Monroe, La.; and Bowman Academy in Orangeburg, S. C. — are alleged to have discriminatory policies that deprive them of direct tax exemptions yet operate under the umbrella of a tax-exempt organization. These allegations constitute an insufficient basis for the only claim made by respondents — a claim for a change in the IRS regulations and practices. Cf. Wright v. Miller, 480 F. Supp. 790, 796 (DC 1979) (“it is purely speculative whether, in the final analysis, any fewer schools would be granted tax exemptions under plaintiffs’ system than under the current IRS system”).
Simon v. Eastern Kentucky Welfare Rights Org., supra, framed its standing discussion in terms of the redressability of the alleged injury. The relief requested by the plaintiffs, however, was simply the cessation of the allegedly illegal conduct. In those circumstances, as the opinion for the Court in Simon itself illustrates, see id., at 40-46, the “redressability” analysis is identical to the “fairly traceable” analysis. See n. 19, supra.
In O’Shea v. Littleton and Rizzo v. Goode, the plaintiffs sought wide-ranging reform of local law enforcement systems. In Los Angeles v. Lyons, by contrast, the plaintiff sought cessation of a particular police practice. The Court concluded in Lyons, however, that this difference did not distinguish the cases for standing purposes as long as the plaintiff could show no realistic threat of being subject to the challenged practice.
We disagree with Justice Stevens’ suggestions that separation of powers principles merely underlie standing requirements, have no role to play in giving meaning to those requirements, and should be considered only under a distinct justiciability analysis. Post, at 789-792. Moreover, our analysis of this case does not rest on the more general proposition that no consequence of the allocation of administrative enforcement resources is judicially cognizable. Post, at 792-793. Rather, we rely on separation of powers principles to interpret the “fairly traceable” component of the standing requirement.
On the merits, the Court found that permitting such exclusive use by school groups was unlawful, because it violated the city’s constitutional obligation, spelled out in an outstanding school-desegregation order, to take no action that would impede the integration of the public schools. Exclusive availabililty of the public parks “significantly enhanced the attractiveness of segregated private schools ... by enabling them to offer complete athletic programs.” 417 U. S., at 569.
Indeed, the Court stressed the importance of a particularized factual record when it stated that it was “not prepared, at this juncture and on this record, to assume the standing of these plaintiffs to claim relief against certain nonexclusive uses by private school groups.” Id., at 570, n. 10. “Without a properly developed record,” said the Court, it was not clear *763that such nonexclusive use “would result in cognizable injury to these plaintiffs.” Id., at 571, n. 10.
The Court said nothing about the plaintiffs’ standing to challenge the use of the parks, exclusive or nonexclusive, by racially discriminatory groups other than schools. It was unnecessary to do so because the Court declined to consider the merits of that challenge on the record before it. Id., at 570-574.
In Norwood v. Harrison, 413 U. S. 455, 467, n. 9 (1973), this Court described the experience of one county in Mississippi: “all white children were withdrawn from public schools and placed in a private academy housed in local church facilities and staffed by the principal and 17 high school teachers of the county system, who resigned in mid-year to accept jobs at the new academy.” The Court observed that similar histories in various other localities in Mississippi were recited by the plaintiffs without challenge. Ibid.
The relatively simple either-or nature of the challenged decision affects the extent to which the initial complaint implicated separation of powers concerns. When the IRS altered its policy concerning the grant of tax exemptions to racially discriminatory schools, see Green v. Connally, 330 F. Supp., at 1156, the plaintiffs were left with an action more closely resembling this lawsuit. We have no occasion to consider here the effect on a plaintiff’s standing of a defendant’s partial cessation of challenged conduct when that partial cessation leaves the plaintiff with a complaint presenting substantially greater uncertainty about standing than the initial complaint did.
