748.This section sets out the procedure for making statutory instruments under the powers in the Act.  Most of the powers to make orders and regulations under the Act are subject to the negative resolution procedure. The power to appoint a day for the commencement of particular provisions of the Act under section 431(2) is not subject to Parliamentary control.  However, the affirmative procedure applies to the following powers:
	the power initially to set the definition, or to extend the scope of, regulated activities under section 22(1) (the type of affirmative procedure applicable to this power is set out in paragraph 26 of Schedule 2);
	the power initially to specify the matters set out in section 21(4), (5), (9) and (10) (the meaning of certain elements of the basic restriction on financial promotion and the exceptions from that restriction);
	any subsequent exercise of the power to specify the matters dealt with in section 21(4) and (5) (the meaning of certain elements of the basic restriction on financial promotion) which has the effect of extending that restriction so as to apply in circumstances in which it did not previously apply;
	the power to add to the activities and investments that are “controlled” for the purposes of section 21;
	the power under section 38, when it is first used, and any subsequent exercise of the power that has the effect of restricting or removing an exemption previously conferred by an order under section 38;
	the power to set the scope of price stabilising rules under section 144(4);
	the power under section 192(b) to vary, remove from or add to the cases in which a person has control for the purposes of Part XII and the equivalent power in section 192(e) in relation to the meaning of “controller” in section 422;
	the power under section 236(5) to amend the definition of open-ended investment company;
	the power for the establishment and regulation of collective investment schemes in Great Britain taking the form of oeics under section 262;
	the power initially to determine the circumstances in which the carrying on of regulated activities by members of the professions is subject to the arrangements set out under section 326(1) and restriction of exemption from the general prohibition under section 327(6)) and any subsequent exercise of those powers so as to restrict those circumstances;
	the power under section 404 authorising a scheme for reviewing past business;
	an order under section 419 defining the business test; and
	the power under paragraph 1 of Schedule 8 to allow any exercisable function conferred on the competent authority to be transferred in order for another person to exercise that function.
