Task: sc_decisiontype

What follows is an opinion from the Supreme Court of the United States. Your task is to identify the type of decision made by the court among the following: Consider "opinion of the court (orally argued)" if the court decided the case by a signed opinion and the case was orally argued. For the 1791-1945 terms, the case need not be orally argued, but a justice must be listed as delivering the opinion of the Court. Consider "per curiam (no oral argument)" if the court decided the case with an opinion but without hearing oral arguments. For the 1791-1945 terms, the Court (or reporter) need not use the term "per curiam" but rather "The Court [said],""By the Court," or "By direction of the Court." Consider "decrees" in the infrequent type of decisions where the justices will typically appoint a special master to take testimony and render a report, the bulk of which generally becomes the Court's decision. This type of decision usually arises under the Court's original jurisdiction and involves state boundary disputes. Consider "equally divided vote" for cases decided by an equally divided vote, for example when a justice fails to participate in a case or when the Court has a vacancy. Consider "per curiam (orally argued)" if no individual justice's name appears as author of the Court's opinion and the case was orally argued. Consider "judgment of the Court (orally argued)" for formally decided cases (decided the case by a signed opinion) where less than a majority of the participating justices agree with the opinion produced by the justice assigned to write the Court's opinion.

Per Curiam.
On April 11, 1962, petitioner pleaded not guilty to federal narcotics charges; thereafter, on July 18, 1962, he was permitted to withdraw this plea and plead guilty; in November 1962, when the case came on for sentencing, he moved to withdraw his guilty plea because of facts and circumstances which had changed since the time of the plea, including petitioner’s extensive cooperation with the Government. The Government acquiesced in this motion, but the district judge denied it, holding that he had no power to permit withdrawal of the plea on such grounds. The court sentenced petitioner to the minimum statutory term of imprisonment and the Court of Appeals affirmed the conviction, 323 F. 2d 936.
The Government now says that it consented to petitioner’s motion to withdraw his plea because it “planned to dismiss the pending indictment against petitioner and substitute lesser charges.” The Government admits that this purpose was not expressly stated and that “it may be that the court was misled.”
In these circumstances, we believe that the court has discretion to permit withdrawal of the plea. See Kercheval v. United States, 274 U. S. 220, 224 (1927). Accordingly, we grant the petition for certiorari, vacate the judgment of the Court of Appeals and remand the case to the District Court for further proceedings in conformity with this opinion.
