Administrative Arrangements Act 1983

An Order shall—

be published in the Government Gazette; and

take effect from the day on which it is published in the Government Gazette, or where—

an earlier day (whether before, on or after the commencement of this Act); or

a later day—

An Order does not invalidate anything done or omitted to be done before the day on which it is published in the Government Gazette.

To the extent to which an Order takes effect from a day that is earlier than the day on which it is published in the Government Gazette, the Order does not operate—

so as to affect, in a manner prejudicial to any person (other than the Crown or a public authority), the rights of that person existing before the day on which it is published in the Government Gazette; or

so as to impose liabilities on any person (other than the Crown or a public authority) in respect of anything done or omitted to be done before the day on which it is published in the Government Gazette.

A provision of the kind referred to in section 3(1)(a) does not apply to or in respect of any Act or statutory instrument or any other instrument or any contract or agreement enacted made or entered into after the day of publication in the Government Gazette of the Order in which the provision is contained or the day on which the provision takes effect, whichever is the later.
