39 U.S.C. § 205 — Procedures of the Board of Governors

(a) The Board directs and controls the Postal Service's spending, and reviews its practices and policies. It also performs whatever other duties this title assigns it. (b) If seats on the Board are vacant, that doesn't weaken the Board's power — as long as enough members remain to form a quorum. (c) The Board acts by majority vote of the members present. Normally, any 6 members present form a quorum for doing business. But there are exceptions: appointing or removing the Postmaster General, and setting the pay of the Postmaster General and Deputy Postmaster General, requires a favorable vote from an absolute majority of all sitting Governors. Appointing or removing the Deputy Postmaster General requires a favorable vote from an absolute majority of sitting Governors plus the member serving as Postmaster General. Other parts of this title may set their own different rules. (d) No U.S. government officer or employee can serve as a Governor at the same time. A Governor can hold another job or office, as long as it doesn't conflict with their duties and powers as a Governor of the Postal Service.
