The clause provides when and how the provisions of the Bill are to come into force, including powers for certain provisions to be brought into force by commencement regulations. The amendments in the group relate to local government schemes and align the coming into force of the Bill with that provided for in respect of the chapter 1 schemes. The amendments provide that chapter 3 of the Bill, to the extent that it has not come into force already, should come into force on 1 October 2023, unless regulations issued by HM Treasury or the Department of Finance in Northern Ireland provide for an earlier date. This change ensures consistency across the public service pension schemes and allows time for local administrators to make detailed preparations for the implementation of the remedy.
