opinion: Per Curiam.
  The Elections Clause of the United States Constitution provides that the “Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.” Art. I, §4, cl. 1 (emphasis added). When Colorado legislators were unable to redraw congressional districts after the 2000 census to accommodate an additional Representative, a state court did it for them. See Beauprez v. Avalos, 42 P. 3d 642 (Colo. 2002). The legislature was able to pass a redistricting plan in 2003, which Colorado’s Governor signed into law. See Colo. Rev. Stat. Ann. §2-1-101.
  Colorado’s attorney general, however, filed an original action in the Colorado Supreme Court to enjoin Colorado’s secretary of state from implementing this new plan, noting that Article V, §44, of the Colorado Constitution limits redistricting to once per census. The Colorado General Assembly intervened in the action to defend its plan. The Colorado Supreme Court granted the injunction, holding that “judicially-created districts are just as binding and permanent as districts created by the General Assembly,” and that the court-drawn plan must remain in effect until the next decennial census. People ex rel. Salazar v. Davidson, 79 P. 3d 1221, 1231 (2003), cert. denied, 541 U. S. 1093 (2004). The court further held that this result did not offend the Elections Clause of the United States Constitution. 79 P. 3d, at 1232.
  Immediately after Salazar was decided, four Colorado citizens — none of whom had participated in Salazar — filed the instant action in Federal District Court. They argued that Article V, §44, of the Colorado Constitution, as interpreted by the Colorado Supreme Court, violates their rights under the Elections Clause.
  The District Court initially determined that it lacked jurisdiction to hear the suit in light of the Rooker-Feldman doctrine, but we vacated and remanded for further proceedings. Lance v. Dennis, 546 U. S. 459 (2006) (per curiam). On remand, the District Court held that the citizen-plaintiffs had standing to bring their Elections Clause challenge. Lance v. Dennis, 444 F. Supp. 2d 1149, 1154-1155 (2006). The court went on, however, to hold that the suit was barred by issue preclusion because the plaintiffs “stand in privity with the Secretary of State and the General Assembly,” who were on the losing side in the Salazar litigation. 444 F. Supp. 2d, at 1161. The concurring judge concluded that appellants lacked standing to sue in the first place. Id., at 1162 (Porfilio, J., concurring in result). Plaintiffs appeal once again.
  Federal courts must determine that they have jurisdiction before proceeding to the merits. Steel Co. v. Citizens for Better Environment, 523 U. S. 83, 94-95 (1998). Article III of the Constitution limits the jurisdiction of federal courts to “Cases” and “Controversies.” One component of the case-or-controversy requirement is standing, which requires a plaintiff to demonstrate the now-familiar elements of injury in fact, causation, and redressability. See Lujan v. Defenders of Wildlife, 504 U. S. 555, 560-561 (1992). “We have consistently held that a plaintiff raising only a generally available grievance about government — claiming only harm to his and every citizen’s interest in proper application of the Constitution and laws, and seeking relief that no more directly and tangibly benefits him than it does the public at large — does not state an Article III case or controversy.” Id., at 573-574. See also Daimler Chrysler Corp. v. Cuno, 547 U. S. 332, 344 (2006) (refusing to create an exception to the general prohibition on taxpayer standing for challenges to state tax or spending decisions, and observing that taxpayer standing has been rejected “because the alleged injury is not ‘concrete and particularized,’ but instead a grievance the taxpayer ‘suffers in some indefinite way in common with people generally’ ” (citation omitted)).
  Our refusal to serve as a forum for generalized grievances has a lengthy pedigree. In Fairchild v. Hughes, 258 U. S. 126 (1922), for example, a citizen sued the Secretary of State and the Attorney General to challenge the procedures by which the Nineteenth Amendment was ratified. We dismissed the suit because it was “not a case within the meaning of.... Article III.” Id., at 129. The plaintiff sought to assert “only the right, possessed by every citizen, to require that the Government be administered according to law and that the public moneys be not wasted.” Ibid. “Obviously,” we held, “this general right does not entitle a private citizen to institute [a suit] in the federal courts.” Id., at 129-130.
  Similarly, in Ex parte Lévitt, 302 U. S. 633 (1937) (per curiam), we dismissed a citizen suit claiming that Justice Black’s appointment to this Court contravened the Constitution’s Ineligibility Clause, Art. I, §6, cl. 2. We found that the petitioner had no interest in the suit “other than that of a citizen and a member of the bar of this Court.” 302 U. S., at 634. That was not enough. To have standing, we observed, a plaintiff must have more than “a general interest common to all members of the public.” Ibid. See also Frothingham v. Mellon, decided with Massachusetts v. Mellon, 262 U. S. 447, 488 (1923) (taxpayer standing cannot be predicated upon an injury the plaintiff “suffers in some indefinite way in common with people generally”). Cf. Tyler v. Judges of Court of Registration, 179 U. S. 405, 406 (1900) (“[E]ven in a proceeding which he prosecutes for the benefit of the public ... [the plaintiff] must generally aver an injury peculiar to himself, as distinguished from the great body of his fellow citizens”).
  A pair of more recent cases further illustrates the point. In United States v. Richardson, 418 U. S. 166 (1974), a federal taxpayer challenged the Government’s failure to disclose certain CIA expenditures as a violation of the Constitution’s Accounts Clause, which requires that “a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published from time to time.” Art. I, §9, cl. 7. Relying on Lévitt, this Court dismissed the claim as a “generalized grievance” that is “plainly undifferentiated and ‘common to all members of the public.’” Richardson, 418 U. S., at 176-177. See also id., at 191 (Powell, J., concurring) (“The power recognized in Marbury v. Madison, 1 Cranch 137 (1803), is a potent one. Its prudent use seems to me incompatible with unlimited notions of taxpayer and citizen standing”).
  The same day, in Schlesinger v. Reservists Comm. to Stop the War, 418 U. S. 208 (1974), we addressed standing to bring a challenge under the Constitution’s Incompatibility Clause, which provides that “no Person holding any Office under the United States, shall be a Member of either House during his Continuance in Office.” Art. I, §6, cl. 2. Citizen-taxpayers brought a lawsuit contending that Members of Congress who were also members of the military Reserves violated the Incompatibility Clause. This Court dismissed for lack of standing. It “reaffirmed] Lévitt in holding that standing to sue may not be predicated upon an interest of the kind alleged here which is held in common by all members of the public, because of the necessarily abstract nature of the injury all citizens share.” 418 U. S., at 220. Refusing to entertain generalized grievances ensures that “there is a real need to exercise the power of judicial review” in a particular case, and it helps guarantee that courts fashion remedies “no broader than required by the precise facts to which the court’s ruling would be applied.” Id., at 221-222. In short, it ensures that courts exercise power that is judicial in nature.
  The instant case parallels Fairchild, Lévitt, and their progeny. The plaintiffs here are four Colorado voters. Three days after the Colorado Supreme Court issued its decision in Salazar, they filed a complaint alleging that “Article V, § 44 of the Colorado Constitution, as interpreted in Salazar, violated [the Elections Clause] of the U. S. Constitution by depriving the state legislature of its responsibility to draw congressional districts.” Lance v. Davidson, 379 F. Supp. 2d 1117, 1122 (2005). In light of the discussion above, the problem with this allegation should be obvious: The only injury plaintiffs allege is that the law — specifically the Elections Clause — has not been followed. This injury is precisely the kind of undifferentiated, generalized grievance about the conduct of government that we have refused to countenance in the past. It is quite different from the sorts of injuries alleged by plaintiffs in voting rights cases where we have found standing. See, e. g., Baker v. Carr, 369 U. S. 186, 207-208 (1962). Because plaintiffs assert no particularized stake in the litigation, we hold that they lack standing to bring their Elections Clause claim.
  Our two decisions construing the term “Legislature” in the Elections Clause do not contradict this holding. Each of these cases was filed by a relator on behalf of the State rather than private citizens acting on their own behalf, as is the case here. See State ex rel. Smiley v. Holm, 184 Minn. 647,238 N. W. 792 (1931) (per curiam), rev’d sub nom. Smiley v. Holm, 285 U. S. 355 (1932); Ohio ex rel. Davis v. Hildebrant, 241 U. S. 565 (1916). In neither case did we address whether a private citizen had alleged a “concrete and particularized” injury sufficient to satisfy the requirements of Article III.
  The judgment of the United States District Court for the District of Colorado is therefore vacated in part, and the case is remanded with instructions to dismiss the Elections Clause claim for lack of standing. We affirm the District Court's dismissal of the Petition Clause claim.
  It is so ordered.
  Qur prior decision in this case did not violate this principle because Rooker-Feldman concerns a district court’s subject-matter jurisdiction, Exxon Mobil Corp. v. Saudi Basie Industries Corp., 544 U. S. 280, 291 (2005), and “there is no unyielding jurisdictional hierarchy,” Ruhrgas AG v. Marathon Oil Co., 526 U. S. 574, 578 (1999).
instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to determine the issue area of the Court's decision. Determine the issue area on the basis of the Court's own statements as to what the case is about. Focus on the subject matter of the controversy rather than its legal basis. In specifying the issue in a legacy case, choose the one that best accords with what today's Court would consider it to be. Choose among the following issue areas: "Criminal Procedure" encompasses the rights of persons accused of crime, except for the due process rights of prisoners. "Civil rights" includes non-First Amendment freedom cases which pertain to classifications based on race (including American Indians), age, indigency, voting, residency, military or handicapped status, gender, and alienage. "First Amendment encompasses the scope of this constitutional provision, but do note that it need not involve the interpretation and application of a provision of the First Amendment. For example, if the case only construe a precedent, or the reviewability of a claim based on the First Amendment, or the scope of an administrative rule or regulation that impacts the exercise of First Amendment freedoms. "Due process" is limited to non-criminal guarantees. "Privacy" concerns libel, comity, abortion, contraceptives, right to die, and Freedom of Information Act and related federal or state statutes or regulations. "Attorneys" includes attorneys' compensation and licenses, along with trhose of governmental officials and employees. "Unions" encompass those issues involving labor union activity. "Economic activity" is largely commercial and business related; it includes tort actions and employee actions vis-a-vis employers. "Judicial power" concerns the exercise of the judiciary's own power. "Federalism" pertains to conflicts and other relationships between the federal government and the states, except for those between the federal and state courts. "Federal taxation" concerns the Internal Revenue Code and related statutes. "Private law" relates to disputes between private persons involving real and personal property, contracts, evidence, civil procedure, torts, wills and trusts, and commercial transactions. Prior to the passage of the Judges' Bill of 1925 much of the Court's cases concerned such issues. Use "Miscellaneous" for legislative veto and executive authority vis-a-vis congress or the states.
