Votes on account permit temporary parliamentary authorisation of interim or exceptional appropriations pending regular budget enactment. The provision permits Parliament to authorise temporary or non standard appropriations from the Consolidated Fund in three situations: advance grants for part of a financial year pending completion of ordinary budgetary procedure; grants for unexpected demands that cannot be detailed in the annual financial statement; and exceptional grants outside current service. Parliament may authorise withdrawals for these purposes, and the usual voting and appropriation procedures apply to such grants and any enabling law.
