Except for those powers, duties, or obligations specifically
vested in the Governors, as distinguished from the Board of
Governors, the Board may delegate the authority vested in it to the
Postmaster General under such terms, conditions, and limitations,
including the power of redelegation, as it deems desirable. The
Board may establish such committees of the Board, and delegate such
powers to any committee, as the Board determines appropriate to
carry out its functions and duties. Delegations to the Postmaster
General or committees shall be consistent with other provisions of
this title, shall not relieve the Board of full responsibility for
the carrying out of its duties and functions, and shall be
revocable by the Governors in their exclusive judgment.
