When a Bill for continuing a temporary enactment has been introduced into Parliament, and, at the date of the expiration of the temporary enactment, has not been passed, that Bill, upon receiving the Governor's assent for and on behalf of the Sovereign (or, if reserved for the signification of the Sovereign's pleasure, upon the Sovereign's assents thereto being proclaimed by the Governor) shall, unless the contrary intention appears therein, be deemed to have taken effect in continuing the temporary enactment on and from the date of the expiration thereof; but no person is liable, or shall be subjected, to any punishment, penalty, or forfeiture for or in respect of anything done or omitted to be done by him, contrary to any provision of the temporary enactment, between the date of its expiration and the date of that assent.
