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:
HODGES v. UNITED STATES.
No. 58.
Argued November 13, 1961.
Decided December 4, 1961.
Quinn O’Connell argued the cause for petitioner. With him on the briefs were Henry B. Weaver, Jr. and Hershel Shanks.
Beatrice Rosenberg argued the cause for the United States. With her on the brief were Solicitor General Cox, Assistant Attorney General Miller and J. F. Bishop.
Per Curiam.
We brought this case here upon the understanding that the question it presented was whether the District Court should have accorded petitioner a hearing under 28 U. S. C. § 2255 when it appeared that no appeal had been perfected from the original judgment of conviction. After a thorough review of the full record, made possible after the case was briefed and argued on the merits, we have concluded that the petition for certiorari was improvidently granted. The record shows that the District Court did in fact conduct a hearing upon the petitioner’s § 2255 motion, 156 F. Supp. 313, but that, the minutes of such hearing have been lost. Whether or not that hearing was adequate need not, however, be determined, for we are satisfied from the record, which includes the trial transcript, that in any event this was a case where no hearing was required under the statute, because “the files and records of the case conclusively show” that the petitioner was entitled to no relief. Therefore, and necessarily without approving or disapproving the view of the Court of Appeals on what now appears an extraneous issue, 108 U. S. App. D. C. 375, 282 F. 2d 858, we dismiss the writ as improvidently granted.
It is so ordered.
