s 93 Power to refuse to confirm purchase notice where land has restricted use by virtue of previous planning permission.
(1) This section applies where a purchase notice is served in respect of land which consists in whole or in part of land which has a restricted use by virtue of an existing planning permission. (2) For the purposes of this section, land is to be treated as having a restricted use by virtue of an existing planning permission if it is part of a larger area in respect of which planning permission has previously been granted (and has not been revoked) and either— (a) it remains a condition of the planning permission (however expressed) that that part shall remain undeveloped or be preserved or laid out in a particular way as amenity land in relation to the remainder, or (b) the planning permission was granted on an application which contemplated (expressly or by necessary implication) that the part should not be comprised in the development for which planning permission was sought, or should be preserved or laid out as mentioned in paragraph (a). (3) Where a copy of the purchase notice is sent to the Secretary of State under section 90(4), although satisfied that the land has become incapable of reasonably beneficial use in its existing state, he need not confirm the notice under section 92(1) if it appears to him that the land having a restricted use by virtue of an existing planning permission ought, in accordance with that permission, to remain undeveloped or, as the case may be, remain or be preserved or laid out as amenity land in relation to the remainder of the large area for which that planning permission was granted.
