194.—(1) This section has effect where, on an application for planning permission to develop any land which consists of or includes the whole or part of any land which has a restricted use by virtue of a previous planning permission, permission is refused or granted subject to conditions and the owner of the land serves a purchase notice.
(2) For the purposes of this section, land has a restricted use by virtue of a previous planning permission if it is part of a larger area in respect of which planning permission was previously granted (and has not been revoked) and either—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 aforesaid.
(3) If a purchase notice is served on a council, the council although satisfied that the land to which the purchase notice relates (or part of that land) has become incapable of reasonably beneficial use, may nevertheless serve a counter-notice if it appears to the council that the land to which the purchase notice relates (or part of that land) ought, in accordance with the previous planning permission, to remain undeveloped or, as the case may be, to remain or be preserved or laid out as amenity land in relation to the remainder of the larger area for which that planning permission was granted.
