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:
IDLEWILD BON VOYAGE LIQUOR CORP. v. EPSTEIN et al.
No. 138.
Argued February 28, 1962.
Decided June 25, 1962.
Charles H. Tuttle argued the cause for petitioner. With him on the briefs was John F. Kelly.
Julius L. Sackman argued the cause for respondents. With him on the briefs were Louis J. Lefkowitz, Attorney General of New York, and Paxton Blair, Solicitor General.
Together with No. 180, Misc., Idlewild Bon Voyage Liquor Corp. v. Bicks et al., U. S. District Judges, on petition for writ of mandamus.
Per Curiam.
The petitioner is in the business of selling bottled wines and liquors for export from the United States and delivery to international airline passengers at their overseas destinations. Upon advice of the Attorney General of New York, the State Liquor Authority informed the petitioner that its business was illegal under the provisions of the New York Alcoholic Beverage Control Law. The petitioner then instituted an action in the United States District Court for the Southern District of New York against the respondents, members of the State Liquor Authority. The complaint asked for a judgment declaring that the state statutes, as applied, were repugnant to the Commerce Clause, the Export-Import Clause, and the Supremacy Clause of the United States Constitution, and for an injunction restraining the State Liquor Authority from interfering with the petitioner’s business.
A request for a three-judge court under 28 U. S. C. §§ 2281, 2284, was denied. Instead, the district judge to whom the request was presented simply retained jurisdiction of the cause, in order to give the state courts an opportunity to pass upon the constitutional issues presented, although there was no relevant litigation then pending in the state courts. 188 F. Supp. 434.
The petitioner appealed to the Court of Appeals for the Second Circuit. That court dismissed the appeal, one judge dissenting. 289 F. 2d 426. Unambiguously stating its opinion that the District Court had acted erroneously, and that “a three-judge district court should have been convened,” the Court of Appeals was nevertheless of the view that it was powerless to take formal corrective action in light of this Court’s decision in Stratton v. St. Louis S. W. R. Co., 282 U. S. 10.
Thereafter the petitioner once again filed a motion in the District Court requesting that a statutory three-judge court be impaneled. The request was again refused upon the ground that the previous ruling made by other judges of the District Court had established “the law of this case,” and that the Court of Appeals’ opinion that a three-judge court should be appointed was merely a “dictum.” 194 F. Supp. 3. We granted certiorari and a motion for leave to file a petition for a writ of mandamus.- 368 U. S. 812.
We agree with the Court of Appeals that a three-judge court should have been convened in this case. When an application for a statutory three-judge court is addressed to a district court, the court’s inquiry is appropriately limited to determining whether the constitutional question raised is substantial, whether the complaint at least formally alleges a basis for equitable relief, and whether the case presented otherwise comes within the requirements of the three-judge statute. Those criteria were assuredly met here, and the applicable jurisdictional statute therefore made it impermissible for a single judge to decide the merits of the case, either by granting or by withholding relief.
In the Stratton case it was held that a court of appeals was precluded from reviewing on the merits a case which should have originally been determined by a court of three judges. Stratton does not stand for the broad proposition that a court of appeals is powerless ever to give any guidance when a single judge has erroneously invaded the province of a three-judge court. The Court of Appeals clearly stated its opinion that a court of three judges ought to have been convened to consider this litigation. That view was correct and should have been followed upon the petitioner’s renewed motion that such a statutory court be impaneled.
We deem it unnecessary to take formal action on the petition for a writ of mandamus. The case will be remanded to the District Court for expeditious action consistent with the views here expressed. Cf. Bailey v. Patterson, 369 U. S. 31, 34.
It is so ordered.
Mr. Justice Frankfurter took no part in the decision of these cases.
Mr. Justice Harlan and Mr. Justice White took no part in the consideration or decision of these cases.
During the pendency of the appeal another judge of the District Court for the Southern District of New York issued a temporary injunction restraining the respondents from harassing the petitioner’s business, but, relying on the original judge’s order, refused a renewed request for a three-judge court.
The Court of Appeals properly rejected the argument that the order of the District Court “was not final and hence unappealable under 28 U. S. C. §§ 1291, 1292,” pointing out that “[a]ppellant was effectively out of court.” 289 F. 2d, at 428.
This is not a case like Chicago, Duluth & Georgian Bay Transit Co. v. Nims, 252 F. 2d ,317, where a three-judge court was requested only in the event that it should first be held that the state statute was by its terms applicable to the plaintiff's business operations.
