7. Where an enactment is not in force and it contains provisions conferring power to make regulations or do any other thing, that power may, for the purpose of making the enactment effective on its commencement, be exercised at any time before its commencement, but a regulation so made or a thing so done has no effect until the commencement of the enactment, except in so far as may be necessary to make the enactment effective on its commencement.
