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 petitions for writs of certiorari to the Court of Appeals for the Fourth Circuit are granted for the purpose of deciding whether it is proper to approve school desegregation plans without considering, at a full evi-dentiary hearing, the impact on those plans of faculty allocation on an alleged racial basis. We hold that the Court of Appeals erred in both these cases in this regard, 345 F. 2d 310, 319-321; 345 F. 2d 325, 328.
Plans for desegregating the public school systems of Hopewell and Richmond, Virginia, were approved by the District Court for the Eastern District of Virginia without full inquiry into petitioners’ contention that faculty allocation on an alleged racial basis rendered the plans inadequate under the principles of Brown v. Board of Education, 347 U. S. 483. The Court of Appeals, while recognizing the standing of petitioners, as parents and pupils, to raise this contention, declined to decide its merits because no evidentiary hearings had been held on this issue. But instead of remanding the cases for such hearings prior to final approval of the plans, the Court of Appeals held that “[wjhether and when such an inquiry is to be had are matters with respect to which the District Court . . . has a large measure of discretion,” and it reasoned as follows:
“When direct measures are employed to eliminate all direct discrimination in the assignment of pupils, a District Court may defer inquiry as to the appropriateness of supplemental measures until the effect and the sufficiency of the direct ones may be determined. The possible relation of a reassignment of teachers to protection of the constitutional rights of pupils need not be determined when it is speculative. When all direct discrimination in the assignment of pupils has been eliminated, assignment of teachers may be expected to follow the racial patterns established in the schools. An earlier judicial requirement of general reassignment of all teaching and administrative personnel need not be considered until the possible detrimental effects of such an order upon the administration of the schools and the efficiency of their staffs can be appraised along with the need for such an order in aid of protection of the constitutional rights of pupils.” 345 F. 2d, at 320-321.
We hold that petitioners were entitled to such full evidentiary hearings upon their contention. There is no merit to the suggestion that the relation between faculty allocation on an alleged racial basis and the adequacy of the desegregation plans is entirely speculative. Nor can we perceive any reason for postponing these hearings: Each plan had been in operation for at least one academic year; these suits had been pending for several years; and more than a decade has passed since we directed desegregation of public school facilities “with all deliberate speed,” Brown v. Board of Education, 349 U. S. 294, 301. Delays in desegregating school systems are no longer tolerable. Goss v. Board of Education, 373 U. S. 683, 689; Calhoun v. Latimer, 377 U. S. 263, 264-265; see Watson v. City of Memphis, 373 U. S. 526.
The judgments of the Court of Appeals are vacated and the cases are remanded to the District Court for evidentiary hearings consistent with this opinion. We, of course, express no views of the merits of the desegregation plans submitted, nor is further judicial review precluded in these cases following the hearings.
Vacated rnd remanded.
