BUCKLEY v. VALEO Syllabus to enforce the Act, including primary responsibility for bringing civil actions against violators, to make rules for carrying out the Act, to temporarily disqualify federal candidates for failing to file required reports, and to authorize convention expenditures in excess of the specified limits, the provisions of the Act vesting such powers in the Commission and the prescribed method of appointment of members of the Commission to the extent that a majority of the voting members are appointed by the President pro tempore of the Senate and the Speaker of the House, violate the Appointments Clause, which provides in pertinent part that the President shall nominate, and with the Senate's advice and consent appoint, all "Officers of the United States," whose appointments are not otherwise provided for, but that Congress may vest the appointment of such inferior officers, as it deems proper, in the President alone, in the courts, or in the heads of departments. Hence (though the Commission's past acts are accorded de facto validity and a stay is granted permitting it to function under the Act for not more than 30 days), the Commission, as presently constituted, may not because of that Clause exercise such powers, which can be exercised only by "Officers of the United States" appointed in conformity with the Appointments Clause, although it may exercise such investigative and informative powers as are in the same category as those powers that Congress might delegate to one of its own committees.
