Rules made by either regulator—
may make different provision for different cases and may, in particular, make different provision in respect of different descriptions of authorised persons, activity or investment,
may make provision for any reference in the rules to an enactment (including an enactment comprised in subordinate legislation) to be read as a reference to that enactment as it has effect from time to time,
may make provision by reference to rules made by the other regulator, as those rules have effect from time to time, and
may contain such incidental, supplemental, consequential and transitional provision as the regulator making the rule considers appropriate.
