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.

Opinion:
JOHNSON et al. v. BOARD OF EDUCATION OF THE CITY OF CHICAGO et al.
No. 81-1097.
Decided June 7, 1982
Per Curiam.
This case was commenced by petitioners challenging the voluntary adoption by the Board of Education of the city of Chicago of racial quotas on enrollment at two high schools. Petitioners alleged that the quotas, purportedly designed to arrest “white flight,” were unlawful because they resulted in the denial of admission to those schools of some black applicants but no white applicants. The District Court upheld the plan, and the Court of Appeals affirmed. 604 F. 2d 504 (CA7 1979). We granted certiorari, 448 U. S. 910 (1980), but then vacated the judgment and remanded the case “for further consideration in light of the subsequent development described in the suggestion of mootness filed by respondents.” 449 U. S. 915 (1980). That development was the entry of a consent decree in a related case, United States v. Board of Education of Chicago, No. 80-C-5124 (ND Ill.), in which the Board of Education agreed to develop a systemwide integration plan, and the Board’s announcement that it had abandoned use of the racial quotas at the two high schools. The Court of Appeals remanded to the District Court to consider the suggestion of mootness. 645 F. 2d 75 (1981). That court, finding that the Board had readopted the quotas, concluded without taking further evidence that the challenge was not moot. The Court of Appeals, agreeing that the case was not moot and relying upon the doctrine of the law of the case, affirmed without reconsidering the constitutional challenge to the racial quotas in light of the subsequent development that the Board argued eliminated or reduced any discriminatory effects of the quotas. 664 F. 2d 1069 (1981). Petitioners have now renewed their request for review.
We agree with the Court of Appeals that the case is not moot and that the subsequent development does not undermine that court’s original decision upholding the racial quotas. However, since if we were to grant certiorari we would consider the constitutional challenge as an original matter, the subsequent development might well be relevant to that consideration. It was for that reason that we vacated the Court of Appeals’ judgment for further consideration in light of the subsequent development. No additional evidence was taken and therefore neither the record nor the District Court or Court of Appeals opinions reflect the subsequent development. We therefore grant certiorari, vacate the judgment, and remand the case with the direction that the matter be consolidated with the ongoing proceeding in the District Court in United States v. Board of Education of Chicago, No. 80-C-5124, so that court may decide petitioners’ challenge on the basis of a complete factual record. Because we have vacated the Court of Appeals’ judgments in this case, the doctrine of the law of the case does not constrain either the District Court or, should an appeal subsequently be taken, the Court of Appeals.
It is so ordered.
Justice Brennan would grant the petition for a writ of certiorari and set the case for oral argument.
Justice White took no part in the consideration or decision of this ease.
