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.
This case represents the aftermath of our decision in Simpson v. Union Oil Co., 377 U. S. 13, where we held that a “consignment” agreement for the sale of gasoline, required by Union Oil of lessees of its retail outlets, violated the Sherman Act, 26 Stat. 209, 15 U. S. C. § 1 et seq. The case was remanded for a hearing on other issues and for a determination of damages. The last sentence of the Court’s opinion stated:
“We reserve the question whether, when all the facts are known, there may be any equities that would warrant only prospective application in damage suits of the rule governing price fixing by the ‘consignment’ device which we announce today.” Id., at 24-25.
On remand, the District Court interpreted this sentence as an invitation to determine if any “equities” were present which would warrant precluding the imposition of damages on Union Oil. Its finding was that an application of the rule announced by this Court to the damages action would be unfair, on the ground that the decision in United States v. General Electric Co., 272 U. S. 476, gave Union Oil a reasonable basis for believing that its actions were entirely lawful. The Court of Appeals affirmed.
The petition for certiorari presents the question whether in this case the principles we announced in Simpson v. Union Oil Co. should be made prospective in the present litigation. We grant the petition on that question and deny it on the other questions tendered; and we reverse the judgment below.
We held when the case was here before that on the facts of record the use of the “consignment” device was within the prohibited ban of price fixing for nonpatented articles, 377 U. S., at 16-24, and that “on the issue of resale price maintenance under the Sherman Act there is nothing left to try, for there was an agreement for resale price maintenance, coercively employed.” Id., at 24.
The question we reserved was not an invitation to deny the fruits of successful litigation to this petitioner. Congress has determined the causes of action that arise from antitrust violations; and there has been an adjudication that a cause of action against respondent has been established. Formulation of a rule of law in an Article III case or controversy which is prospective as to the parties involved in the immediate litigation would be most unusual, especially where the rule announced was not innovative. Since parties in other cases might be shown to have structured product distribution on quite different considerations, we reserved the question whether in some of those other situations equity might warrant the conclusion that prospective application was the only fair course.
Reversed.
