BUCKLEY v. VALEO 1 Per Curiam it is not now disputed-that the Clause controls the appointment of the members of a typical administrative agency even though its functions, as this Court recognized in Humphrey's Executor v.

Appellees also rely on the Twelfth Amendment to the Constitution insofar as the authority of the Commission to regulate practices in connection with the Presidential election is concerned. This Amendment provides that certificates of the votes of the electors be "sealed [and]
