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:
JOHNSON v. UNITED STATES.
No. 531,
Misc.
Decided March 4, 1957.
William H. Timbers for petitioner.
Solicitor General Rankin, Assistant Attorney General Olney and Beatrice Rosenberg for the United States.
Per Curiam.
The petition for writ of certiorari is granted, as is leave to proceed in forma pauperis.
By the Act of June 25, 1910, 86 Stat. 866, as now enlarged in 28 U. S. C. § 1915, Congress provided for proceedings in forma pauperis on appeal unless “the trial court certifies in writing that it [the appeal] is not taken in good faith.” Such certification is not final in the sense that the convicted defendant is barred from showing that it was unwarranted and that an appeal should be allowed. Of course, certification by the judge presiding at the trial carries great weight but, necessarily, it cannot be conclusive. Upon a proper showing a Court of Appeals has a duty to displace a District Court’s certification. Moreover, a Court of Appeals must, under Johnson v. Zerbst, 304 U. S. 458, afford one who challenges that certification the aid of counsel unless he insists on being his own. Finally, either the defendant or his assigned counsel must be enabled to show that the grounds for seeking an appeal from the judgment of conviction are not frivolous and do not justify the finding that the appeal is not sought in good faith. This does not require that in every such case the United States must furnish the defendant with a stenographic transcript of the trial. It is essential, however, that he be assured some appropriate means — such as the district judge’s notes or an agreed statement by trial counsel — of making manifest the basis of his claim that the District Court committed error in certifying that the desired appeal was not pursued in good faith. See Miller v. United States, 317 U. S. 192, 198.
Since here the Court of Appeals did not assign counsel to assist petitioner in prosecuting his application for leave to appeal in forma pauperis and since it does not appear that the Court of Appeals assured petitioner adequate means of presenting it with a fair basis for determining whether the District Court’s certification was warranted, the judgment below must be vacated and the case remanded to the Court of Appeals for proceedings not inconsistent with this opinion.
So ordered.
