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:
SCHOOL DISTRICT OF OMAHA et al. v. UNITED STATES et al.
No. 76-705.
Decided June 29, 1977
Per Curiam.
This school desegregation case involves the School District of Omaha, Neb. The District Court in a comprehensive opinion extensively reviewed the evidence presented by the parties, and recognized that there was considerable racial imbalance in school attendance patterns. Applying a legal standard which placed the burden of proving intentional segre-gative actions on the respondents, and which regarded the natural and foreseeable consequences of petitioners' conduct as "neither determinative nor immaterial” but as “one additional factor to be weighed,” the District Court concluded that the respondent had not carried the burden of proving a deliberate policy of racial segregation. 389 F. Supp. 293. On appeal, the Court of Appeals rejected the legal standard applied by the District Court, 521 F. 2d 530, stating that’ a “presumption of segregative intent” arises from actions' or omissions whose natural and foreseeable result is to “bring about or maintain segregation.” Id., at 535. Reviewing the facts found by the District Court concerning faculty assignment, student transfers, optional attendance zones, school construction, and the deterioration of one high school in the district, the Court of Appeals generally accepted these factual findings. In each instance, however, it concluded that there was sufficient evidence under the legal standard it adopted to shift the burden of proof to the petitioners. Finding that in no instance had the petitioners carried their rebuttal burden, the Court of Appeals remanded for the formulation of a sys-temwide remedy. We denied certiorari. 423 U. S. 946.
Following the explicit instruction of the Court of Appeals, the District Court promulgated an extensive plan involving, among other elements, the systemwide transportation of pupils. On petitioners’ appeal, the Court of Appeals for the Eighth Circuit affirmed. 541 F. 2d 708.
In Washington v. Davis, 426 U. S. 229, 239 (1976), we said:
“[0]ur cases have not embraced the proposition that a law or other official act, without regard to whether it reflects a racially discriminatory purpose, is unconstitutional solely because it has a racially disproportionate impact.”
We restated and amplified the implications of this holding in Arlington Heights v. Metropolitan Housing Dev. Corp., 429 U. S. 252 (1977).
Neither the Court of Appeals nor the District Court, in addressing itself to the remedial plan mandated by the earlier decision of the Court of Appeals, addressed itself to the inquiry required 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 segregative 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 and Dayton.
It is so ordered.
