(1) The regulatory fine is governed by the statute that is applicable at the time of the act.
(2) If the regulatory fine imposable is modified during commission of the act, the statute in force at the time of completion of the act applies.
(3) If the statute in force at the time of completion of the act is amended prior to the decision, the most lenient statute applies.
(4) A statute which is to apply for a certain period of time only applies to acts committed while it is in force, even if it is no longer in force. This does not apply if there is other statutory provision to the contrary.
(5) Subsections (1) to (4) apply accordingly to incidental consequences of a regulatory offence.
