Regulation 16 Revocation or modification of express consent
If a local planning authority are satisfied that it is expedient, they may by order revoke or modify an express consent, subject to paragraphs (2) to (6) below.
An order under paragraph (1) above shall not take effect without the approval of the Secretary of State, which may be granted with or without modifications.
When an authority submit an order made under this regulation to the Secretary of State for approval, they shall serve notice on the person who applied for the express consent, the owner and the occupier of the land affected and any other person who, in their opinion, will be affected by the order, specifying a period of at least 28 days from the service of the notice, within which an objection may be made, as provided in paragraph (4) below.
If, within the period specified in the notice, an objection to the order is received by the Secretary of State from any person on whom notice is served, the Secretary of State shall, before approving the order, give to that person and to the local planning authority an opportunity of appearing before and being heard by a person appointed by him.
The power to make an order under this regulation may be exercised–
in a case which involves the carrying out of building or other operations, at any time before those operations have been completed;
in any other case, at any time before the display of advertisements is begun.
In a case to which paragraph (5)(a) above applies, the revocation or modification of consent shall not affect such operations as have already been carried out.
