Whenever all or part of any Budget Authority (BA) provided by the Congress is deferred, the President must transmit a message to the Congress describing the deferrals. At any time, either house of Congress may pass a resolution disapproving this deferral of BA, thus requiring that the funds be made available for obligation. When no congressional action is taken, deferrals may remain in effect until, but not beyond, the end of the Fiscal Year (FY). If the funds remain available beyond the end of a FY and continued deferral of their use is desired, the President must transmit a new special message to the Congress.
