Termination of planning permission by reference to time limit
64.—(1) Subsections (2) to (6) shall have effect where by virtue of section 61 or 62, a planning permission is subject to a condition that the development to which the permission relates must be begun before the expiration of a particular period and that development has been begun within that period but the period has elapsed without the development having been completed.
(2) If the council is of the opinion that the development will not be completed within a reasonable period, it may serve a notice (“a completion notice”) stating that the planning permission will cease to have effect at the expiration of a further period specified in the notice.
(3) The period so specified must not be less than 12 months after the notice takes effect.
(4) A completion notice must be served—
(a)on the owner of the land,
(b)on the occupier of the land, and
(c)on any other person who in the opinion of the council will be affected by the notice.
(5) The council may withdraw a completion notice at any time before the expiration of the period specified in it as the period at the expiration of which the planning permission is to cease to have effect.
(6) If it does so it must immediately give notice of the withdrawal to every person who was served with the completion notice.
