Petitioners in this case attacked the overcrowding in Florida’s prisons as violative of the Cruel and Unusual Punishments Clause of the Eighth Amendment, made applicable to the States by the Fourteenth. A single District Judge found substantial constitutional violations and issued a preliminary injunction ordering the Division of Corrections either to reduce the inmate population or to increase prison capacity. In an en banc decision, the United States Court of Appeals for the Fifth Circuit vacated the District Court’s decision on the ground that only a three-judge court convened in accordance with 28 U. S. C. § 2281 could order such relief. 539 F. 2d 547 (1976).
On its face, the complaint that initiated this case involved no challenge to state statutes or regulations. There was thus no reason at the beginning of this litigation to suspect that a three-judge court should hear the case. See Moody v. Flowers, 387 U. S. 97, 104 (1967); Baxter v. Palmigiano, 425 U. S. 308 (1976); Morales v. Turman, ante, p. 322. In granting equitable relief, however, the District Court contemplated as one means of relieving the prison system’s unconstitutional overcrowding the possibility that state prison officials would have to violate their statutory duty to continue to accept custody of prisoners properly committed to them. The Court of Appeals concluded that such equitable relief could be granted only by a three-judge court, apparently because it viewed the possible temporary suspension of an otherwise valid state statute to effectuate federally mandated relief as equivalent to finding that statute unconstitutional.
We cannot agree. The applicability of § 2281 as written turns on whether a state statute is alleged to be unconstitutional, not on whether an equitable remedy for unconstitutional state administrative behavior ultimately impinges on duties imposed under concededly constitutional state statutes. To hold otherwise would require postponing the threshold question of jurisdiction until the merits of the controversy had been fully resolved and the broad outlines of equitable relief discerned. Section 2281 embodies no such wasteful and uncertain mandate.
Since we conclude that the single District Judge properly exercised full jurisdiction in this case, and that his judgment is, therefore, reviewable on the merits in the Court of Appeals (28 U. S. C. § 1291), the petition for a writ of certiorari and the motion for leave to proceed in forma pauperis are granted, the judgment is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
What follows is an opinion from the Supreme Court of the United States. Your task is to determine whether the decision of the court whose decision the Supreme Court reviewed was itself liberal or conservative. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. The lower court's decision direction is unspecifiable if the manner in which the Supreme Court took jurisdiction is original or certification; or if the direction of the Supreme Court's decision is unspecifiable and the main issue pertains to private law or interstate relations
