opinion: 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 whether administrative action occurred in the context of the case prior to the onset of litigation. The activity may involve an administrative official as well as that of an agency. To determine whether administration action occurred in the context of the case, consider the material which appears in the summary of the case preceding the Court's opinion and, if necessary, those portions of the prevailing opinion headed by a I or II. Action by an agency official is considered to be administrative action except when such an official acts to enforce criminal law. If an agency or agency official "denies" a "request" that action be taken, such denials are considered agency action. Exclude: a "challenge" to an unapplied agency rule, regulation, etc.; a request for an injunction or a declaratory judgment against agency action which, though anticipated, has not yet occurred; a mere request for an agency to take action when there is no evidence that the agency did so; agency or official action to enforce criminal law; the hiring and firing of political appointees or the procedures whereby public officials are appointed to office; attorney general preclearance actions pertaining to voting; filing fees or nominating petitions required for access to the ballot; actions of courts martial; land condemnation suits and quiet title actions instituted in a court; and federally funded private nonprofit organizations.
