opinion: VETERANS OF THE ABRAHAM LINCOLN BRIGADE v. SUBVERSIVE ACTIVITIES CONTROL BOARD.
  No. 65.
  Argued December 9, 1964.
  Decided April 26, 1965.
  Leonard B. Boudin argued the cause for petitioner. With him on the briefs were Victor Rabinowitz and David Rein.
  Kevin T. Maroney and Bruce J. Terris argued the cause for respondent. With them on the brief were Solicitor General Cox, Assistant Attorney General Yeagley and Robert L. Keuch.
  Melvin L. Wulf and Marvin M. Karpatkin filed a brief for the American Civil Liberties Union, as amicus curiae, urging reversal.
  Per Curiam.
  Petitioner was ordered by the Subversive Activities Control Board to register as a Communist-front organization under § 7 of the Subversive Activities Control Act of 1950, as amended, 64 Stat. 993, 50 U. S. C. § 786 (1958 ed.), and the Court of Appeals for the District of Columbia Circuit affirmed. 117 U. S. App. D. C. 404, 331 F. 2d 64. We granted certiorari, 377 U. S. 989. In this case, the order to register was based almost exclusively on events before 1950, and very largely on events before 1940. The hearings themselves were concluded in November 1954, more than 10 years ago. On so stale a record we do not think it is either necessary or appropriate that we decide the serious constitutional questions raised by the order. See American Committee for Protection of Foreign Born v. Subversive Activities Control Board, ante, p. 503. The judgment is vacated and the cause remanded for proceedings consistent with this opinion.
  It is so ordered.
  Mr. Justice White took no part in the decision of this case.

instruction: 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.
