|1.||the action of the President in retaining unsigned a bill passed by Congress within the last ten days of a session and thus causing it to die|
|2.||any similar action by a state governor or other chief executive|
An automatic veto of a bill that occurs if the president or governor neither signs nor vetoes a bill within ten days of receiving it — as long as the legislature adjourns during that period. If the legislature convenes during that period, the bill will automatically become law. A pocket veto cannot be overridden by the legislature, though the bill can be reintroduced at the next legislative session.
