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.

Pee Curiam.
On January 15, 1973, respondent filed a complaint in the District Court seeking to compel the petitioner, as Administrator of the Environmental Protection Agency, to allot among the States the full sums authorized to be appropriated for fiscal years 1973 and 1974 by § 207 of the Federal Water Pollution Control Act, as added by the Amendments of 1972, 86 Stat. 839, 33 U. S. C. § 1287 (1970 ed., Supp. II), for federal grants to municipalities for construction of publicly owned waste treatment works. Although conceding in the trial court that the Administrator had a measure of discretion in making the allotments authorized by § 205 of the Act, 86 Stat. 837, 33 U. S. C. § 1285 (1970 ed., Supp. III), respondent asserted that the Administrator had abused his discretion by allotting only 45% of the sums authorized to be appropriated by § 207. In sustaining respondent’s position, the District Court rejected the holding by the United States District Court for the District of Columbia in City of New York v. Ruckelshaus, 358 F. Supp. 669 (1973), that the Administrator has no discretion to allot less than the full amounts authorized by the Act. The Court of Appeals proceeded on the premise that there was discretion to control or delay allotments but concluded that further proceedings were essential to determine whether the Administrator’s discretion had been abused. The Administrator petitioned for certiorari, asserting that the exercise of his discretion to allot funds under § 205 is not subject to judicial review. We granted certiorari, 416 U. S. 969 (1974), and heard the case with Train v. City of New York, ante, p. 35.
We held in Train v. City of New York that the Administrator has no authority under § 205 to allot less than the full amounts sought to be appropriated under § 207. Because that holding is at odds with the premise underlying the judgment of the Court of Appeals, we vacate the judgment of the Court of Appeals and remand the case for further proceedings consistent with this opinion and with the opinion in Train v. City of New York.
So ordered.
Mr. Justice Douglas concurs in the result.
The petition also asserted that the doctrine of sovereign immunity foreclosed ordering the Administrator to allot funds that he had withheld in the course of exercising his discretion under the Act. In light of Train v. City of New York, ante, p. 35, and our disposition of the instant case, we need not address this question.
