(b)  if a choice of words is indicated in that text, the words remaining after the omission of the words irrelevant to the offence.

(2)  If the reference to a provision in Column 1 of Schedule 2 is qualified by words that restrict its operation to specified kinds of offence or to offences committed in specified circumstances, an offence created by the provision is a prescribed offence only if it is an offence of a kind so specified or is committed in the circumstances so specified.

(3)  For the purposes of any proceedings for an offence created by a provision specified in Column 1 of Schedule 2, the prescribed expression for the offence is taken to relate to the offence created by the provision, as the provision was in force when the offence is alleged to have been committed.

(4)  The amendment or repeal of a prescribed expression does not affect the validity of any information, complaint, summons, warrant, notice, order or other document in which the expression is used.

(5)  Subclause (4) applies to any information, complaint, summons warrant, notice, order or other document (whether issued, given or made before or after the amendment or repeal) that relates to an offence alleged to have been committed before the amendment or repeal.
