opinion: BRENNAN et al. v. ARMSTRONG et al.
  No. 76-809.
  Decided June 29, 1977
  Per Curiam.
  This school desegregation case involves the school system in the city of Milwaukee, Wis. The District Court here made various findings of segregative acts on the part of petitioner School Board members, appointed a Special Master “to develop a plan for the desegregation of the Milwaukee public school system,” and certified its order for interlocutory appeal to the Court of Appeals for the Seventh Circuit. Amos v. Board of School Directors, 408 F. Supp. 765. The Court of Appeals, observing that there was “an unexplained hiatus between specific findings of fact and conclusory findings of segregative intent,” stated that the District Court is “entitled to a presumption of consistency” and concluded that the findings of the District Court were not clearly erroneous. 539 F. 2d 625. Neither the District Court in ordering development of a remedial plan, nor the Court of Appeals in affirming, addressed itself to the inquiry mandated by our opinion in Dayton Board of Education v. Brinkman, ante, p. 406, in which we said:
  “If such violations are found, the District Court in the first instance, subject to review by the Court of Appeals, must determine how much incremental segrega-tive effect these violations had on the racial distribution of the Dayton school population as presently constituted, when that distribution is compared to what it would have been in the absence of such constitutional violations. The remedy must be designed to redress that difference, and only if there has been a systemwide impact may there be a systemwide remedy.” Ante, at 420.
  The petition for certiorari is accordingly granted, the judgment of the Court of Appeals is .vacated, and the case is remanded for reconsideration in the light of Arlington Heights v. Metropolitan Housing Dev. Corp., 429 U. S. 252 (1977), and Dayton.
instruction: 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.
