12.—(1) The appropriate authority may by order direct a public service pension scheme to be wound up if they are satisfied that—
(a)the scheme, or any part of it, ought to be replaced by a different scheme, or
(b)the scheme is no longer required.
(2) Paragraph (2) of Article 11 applies for the purposes of this Article as it applies for the purposes of that, but as if references to the Authority were to the appropriate authority.
(3) In this Article, “the appropriate authority”, in relation to a scheme, means such Minister of the Crown or government department as may be designated by the Treasury or the Department of Finance and Personnel as having responsibility for the particular scheme.
(4) An order under this Article must include such directions with respect to the manner and timing of the winding up as the appropriate authority thinks appropriate.
(5) Such an order may, as the appropriate authority thinks appropriate, adapt, amend or repeal any enactment in which the scheme is contained or under which it is made.
