Effect of amendments: statutory amendments do not revive lapsed provisions or disturb accrued rights, liabilities, or ongoing proceedings. Amendments, repeals, supersessions or rescissions of rules, notifications or orders under the Act do not operate retrospectively unless expressly intended: they do not revive lapsed provisions or affect prior operation. Rights, privileges, obligations and liabilities already acquired or incurred remain intact, and penalties, forfeitures, investigations, legal proceedings and remedies relating to offences under the prior instrument may be continued or enforced as if the instrument had not been changed.
