opinion: PENNSYLVANIA PUBLIC UTILITY COMMISSION v. PENNSYLVANIA RAILROAD CO.
  No. 375.
  Decided December 13, 1965.
  William A. Goichman and Joseph C. Bruno for appellant.
  Hugh B. Cox and Windsor F. Cousins for appellee.
  Per Curiam.
  In the three-judge District Court from which this appeal comes to us, the Pennsylvania Railroad Company sued to enjoin the enforcement of a duly promulgated order of the Pennsylvania Public Utility Commission on the sole ground that the order conflicted with a federal statute. The Commission, among other defenses, contended that the federal statute was unconstitutional, but the District Court decided the case in favor of the railroad and issued an appropriate injunction. 240 F. Supp. 233.
  It follows from our recent decision in Swift & Co. v. Wickham, ante, p. 111, that the injunction sought by the railroad, being based on incompatibility between the state order and the federal statute, was not grounded in the “unconstitutionality” of a state measure so as to require a three-judge tribunal under 28 U. S. C. § 2281 (1964 ed.). Nor is § 2282, requiring such a tribunal in order to enjoin “any Act of Congress for repugnance to the Constitution,” invoked by the Commission’s defense that the federal statute is unconstitutional; it is settled that this provision “does not provide for a case where the validity of an Act of Congress is merely drawn in question, albeit that question be decided, but only for a case where there is an application for an interlocutory or permanent injunction to restrain the enforcement of an Act of Congress.” Garment Workers v. Donnelly Co., 304 U. S. 243, 250.
  Because a three-judge court was not required to adjudicate this suit, this Court has no jurisdiction under 28 U. S. C. § 1253 (1964 ed.) to entertain a direct appeal. It does not appear from the record that the Commission lodged a protective appeal in the Court of Appeals, and the time to do so has almost certainly expired. The appeal to this Court occurred before Swift & Co. v. Wick-ham, supra, was decided, and there is no reason why the Commission should be deprived of appellate review. In accordance with precedent, we vacate the judgment below and remand the case to the District Court so that it may enter a fresh decree from which a timely appeal may be taken to the Court of Appeals. See Phillips v. United States, 312 U. S. 246, 254.
  It is so ordered.
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.
