Subject to subsection (2) below, sections 15 and 16 above shall not apply in relation to appointments by a relevant authority or committee of a relevant authority to any body in so far as different provision is made by arrangements approved by the authority or committee—
Arrangements approved under subsection (1) above in relation to any body shall not affect any duty imposed by virtue of section 15(1)(c), (d) or (e) or (2) above on a relevant authority or committee to review the representation of different political groups on that body; and, accordingly, such arrangements shall cease to have effect when any such duty arises.
The Secretary of State may, for the purpose of securing what appears to him to be the appropriate representation of different political groups on any sub-committee falling within subsection (4) below, by regulations make such provision as he thinks fit.
The sub-committees that fall within this subsection are those to which appointments may be made by bodies to which section 15 above applies but which are not themselves such bodies.
Without prejudice to the generality of subsection (3) above, regulations under that subsection may contain provision applying, with or without modifications, any provision made by or under section 15 or 16 above, subsections (1) and (2) above or Schedule 1 to this Act.
