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.
The petition for writ of certiorari to the United States Court of Appeals for the District of Columbia Circuit is granted. Charged in a three-count indictment for violation of R. S. § 102, as amended, 2 U. S. C. § 192, for failure to answer three questions put to him by a subcommittee of the Internal Security Subcommittee of the Senate Committee on the Judiciary, the petitioner, having waived trial by jury, was found guilty on all counts and sentenced to six months’ imprisonment and to pay a fine of $1,000. After the sentence was sustained by the Court of Appeals, 99 U. S. App. D. C. 360, 240 F. 2d 46, this Court, having granted a petition for certiorari, remanded the case, 354 U. S. 930, to the Court of Appeals for reconsideration in light of Watkins v. United States, 354 U. S. 178. On reargument before the Court of Appeals sitting en banc, a divided court again affirmed the conviction. 102 U. S. App. D. C. 264, 252 F. 2d 828.
The broad scope of authority vested in Congress to conduct investigations as an incident to the “legislative Powers” granted by the Constitution is not questioned. See Watkins v. United States, supra, at 215. But when Congress seeks to enforce its investigating authority through the criminal process administered by the federal judiciary, the safeguards of criminal justice become operative. The subject matter of inquiry before the subcommittee at which petitioner appeared as a witness concerned the recantation of prior testimony by a witness named Matusow. In the course of the hearing, the questioning of petitioner entered upon a “brief excursion,” 99 U. S. App. D. C. 360, 367, 240 F. 2d 46, 53, into proposed legislation barring Communists from practice at the federal bar, a subject not within the subcommittee’s scope of inquiry as authorized by its parent committee. Inasmuch as petitioner’s refusal to answer related to questions not clearly pertinent to the subject on which the two-member subcommittee conducting the hearing had been authorized to take testimony, the conditions necessary to sustain a conviction for deliberately refusing to answer questions pertinent to the authorized subject matter of a congressional hearing are wanting. Watkins v. United States, supra. The judgment of the Court of Appeals is therefore reversed and the cause remanded to the District Court with directions to dismiss the indictment.
