(1)If it appears to the Ministers, after consultation with the Authority, that for the purpose of improving the marketing of eggs it is expedient for the Authority to perform any functions additional to those conferred by the foregoing provisions of this Part of this Act, and that those additional functions neither—
(a)consist wholly or in part of the buying or selling of eggs or egg products except in so far as such buying or selling may be requisite for the purposes of research or other experimental work or for purposes of demonstration; nor
(b)are similar in character to functions conferred on the Authority by section 8 of this Act,
then, subject to subsection (2) of this section, the Ministers may, if they think fit, confer those additional functions on the Authority for that purpose by order; and any order under this subsection may be varied or revoked by a subsequent order thereunder.
(2)An order under subsection (1) of this section, other than an order in the case of which—
(a)so far as it confers additional functions on the Authority otherwise than by varying a previous order, the Ministers certify that, in their opinion, all the additional functions so conferred are similar in character to functions conferred on the Authority by sections 4 to 7 of this Act; or
(b)so far as it varies a previous order, the Ministers certify that, in their opinion, all the functions conferred by the original order as it will have effect in consequence of the varying order will be functions similar in character as aforesaid; or
(c)so far as it revokes any previous order without itself conferring any functions on the Authority, a certificate under this section was given under the previous order,
shall not be made unless a draft of the order has been laid before Parliament and approved by a resolution of each House of Parliament.
