The U.S. Postal Service is established under the provisions of the Postal Reorganization Act (the Reorganization Act) of 1970, Public Law 91-375, 84 Stat. 719, as amended by the Postal Accountability and Enhancement Act of 2006 (PAEA), Public Law 109-435, 120 Stat. 3198, as an independent establishment of the executive branch of the Government of the United States, under the direction of a Board of Governors, with the Postmaster General as its chief executive officer. The Board of Governors of the Postal Service (the Board) directs the exercise of its powers through management that is expected to be honest, efficient, economical, and mindful of the competitive business environment in which the Postal Service operates. The Board consists of nine Governors appointed by the President, by and with the advice and consent of the Senate, to represent the public interest generally, together with the Postmaster General and Deputy Postmaster General.

Except for powers, duties, or obligations specifically vested in the Governors by law, the Board may delegate its authority to the Postmaster General under such terms, conditions, and limitations, including the power of redelegation, as it finds desirable. The bylaws of the Board are the framework of the system through which the Board monitors the exercise of the authority it has delegated, measures progress toward the goals it has set, and shapes the policies to guide the future development of the Postal Service. Delegations of authority do not relieve the Board of full responsibility for carrying out its duties and functions, and are revocable by the Governors in their exclusive judgment.
