20.Section 4 gives the Scottish Ministers a freestanding regulation-making power to make any incidental, supplementary, consequential, transitional, transitory or saving provision that they consider appropriate for the purposes of, or in connection with, or for giving full effect to, the Act. Subsection (2) allows such regulations to modify any legislation, including the Act itself and in doing so, the regulations would be subject to the affirmative procedure but otherwise are subject to the negative procedure. The ability to make different provision for different purposes under this section enables a regulation-making power to be used in different ways in different circumstances.
