The Secretary of State may by regulations require a relevant local planning authority to make arrangements under section 101 of the 1972 Act for such relevant planning functions as are prescribed—
to be discharged by a committee, sub-committee or officer of the authority;
to be discharged by a committee, sub-committee or officer of the authority in prescribed circumstances.
The regulations may —
prescribe the terms of the arrangements (which may include exceptions) and any permitted variations in those terms;
provide for the arrangements to confer a discretion on any person in connection with the delegation of a function.
Where arrangements required by the regulations are in force in relation to a relevant planning function, the function may only be exercised in accordance with the arrangements (and section 101(4) of the 1972 Act does not apply).
