OCTOBER TERM, 1975 Per Curiam 424 U. S. acting 2 U. S. C. § 437h (1970 ed., Supp. IV), 9 intended to provide judicial review to the extent permitted by Art. III. In our view, the complaint in this case demonstrates that at least some of the appellants have a sufficient "personal stake" 1o in a determination of the consti- tutional validity of each of the challenged provisions to present "a real and substantial controversy admitting of specific relief through a decree of a conclusive character, as distinguished from an opinion advising what the law would be upon a hypothetical state of facts." Aetna Life Ins. Co. v. Haworth, supra, at 241.11 I.

Court has held, for instance, that an organization "may assert, on behalf of its members, a right personal to them to be protected from compelled disclosure ... of their affiliation." NAACP v. Alabama, 357 U. S. 449, 458 (1958). See also Bates v. Little Rock, 361 U. S. 516, 523 n. 9 (1960). Similarly, parties with sufficient concrete interests at stake have been held to have standing to raise constitutional questions of separation of powers with respect to an agency designated to adjudicate their rights. Palmore v. United States, 411 U. S. 389 (1973); Glidden Co. v. Zdanok, 370 U. S. 530 (1962); Coleman v. Miller, 307 U. S. 433 (1939). 11 Accordingly, the two relevant certified questions are answered as follows: 1. Does the first sentence of § 315 (a) of the Federal Election Campaign Act, as amended, 2 U. S. C. § 437h (a) (1970 ed., Supp. IV), in the context of this action, require courts of the United States to render advisory opinions in violation of the "case or controversy" requirement of Article III, § 2, of the Constitution of the United States?
