Task: sc_authoritydecision

What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of "             nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Per Curiam.
The motion to strike the brief of the United States as amicus curiae is denied.
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.
