What follows is an opinion from the Supreme Court of the United States. Your task is to identify the disposition of the case, that is, the treatment the Supreme Court accorded the court whose decision it reviewed. The information relevant to this variable may be found near the end of the summary that begins on the title page of each case, or preferably at the very end of the opinion of the Court. For cases in which the Court granted a motion to dismiss, consider "petition denied or appeal dismissed". There is "no disposition" if the Court denied a motion to dismiss.

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.
