(1)If, having regard to the development plan and to any other material considerations, it appears to a local planning authority that it is expedient in the interests of the proper planning of their area (including the interests of amenity)—
(a)that any use of land should be discontinued or that any conditions should be imposed on the continuance of a use of land; or
(b)that any buildings or works should be altered or removed,
they may by order—
(i)require the discontinuance of that use, or
(ii)impose such conditions as may be specified in the order on the continuance of it, or
(iii)require such steps as may be so specified to be taken for the alteration or removal of the buildings or works,
as the case may be.
(2)An order under this section may grant planning permission for any development of the land to which the order relates, subject to such conditions as may be specified in the order.
(3)Section 97 shall apply in relation to any planning permission granted by an order under this section as it applies in relation to planning permission granted by the local planning authority on an application made under this Part.
(4)The power conferred by subsection (2) includes power, by an order under this section, to grant planning permission, subject to such conditions as may be specified in the order—
(a)for the retention, on the land to which the order relates, of buildings or works constructed or carried out before the date on which the order was submitted to the Secretary of State under section 103; or
(b)for the continuance of a use of that land instituted before that date.
(5)Any planning permission granted in accordance with subsection (4) may be granted—
(a)so as to take effect from the date on which the buildings or works were constructed or carried out, or the use was instituted, or
(b)in the case of buildings or works constructed or a use instituted in accordance with planning permission granted for a limited period, so as to take effect from the end of that period.
(6)Where the requirements of an order under this section will involve the displacement of persons residing in any premises, it shall be the duty of the local planning authority, in so far as there is no other residential accommodation suitable to the reasonable requirements of those persons available on reasonable terms, to secure the provision of such accommodation in advance of the displacement.
(7)Subject to section 103(8), in the case of planning permission granted by an order under this section, the authority referred to in sections 91(1)(b) and 92(4) is the local planning authority making the order.
