Task: songer_casetyp1_3-3-2

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "First Amendment - speech and other expression". 

PER CURIAM.
Appellants’ complaint asks a declaration that Sections 5 through 11 of the Communist Control Act of 1954, 68 Stat. 775, [50 U.S.C.A. §§ 782, 784, 789, 791, 792a, 793, 844,] are invalid, and an injunction to restrain the Attorney General and the Subversive Activities Control Board from enforcing these sections against the plaintiff Union. The complaint says the Attorney General threatened to enforce them immediately, by filing a petition with the Board, and that irreparable harm to the Union and its members would result.
The plaintiffs appeal from a summary judgment for the defendants. Pending the appeal, the Attorney General petitioned the Board “for an order, after appropriate proceedings, determining that the United Electrical, Radio and Machine Workers of America is a Communist-infiltrated organization as defined by Section 3 of the Subversive Activities Control Act of 1950, as amended by the Communist Control Act of 1954.”
We see no pertinent exception to the usual rule that a court will not interfere with administrative proceedings, which are not on their face incapable of affording due process, before final administrative action adverse to the complainant has been taken. Communist Party v. McGrath, D.C., 96 F.Supp. 47.
