“(1) the Upper Tribunal shall … have power from time to time, on the application of any person interested in any freehold land affected by any restriction arising under covenant or otherwise as to the user thereof or the building thereon, by order wholly or partially to discharge or modify any such restriction on being satisfied – … (aa) that (in a case falling within sub-section (1A) below) the continued existence thereof would impede some reasonable user of the land for public or private purposes or, as the case may be, would unless modified so impede such user; or … (c) that the proposed discharge or modification will not injure the persons entitled to the benefit of the restriction. and an order discharging or modifying a restriction under this subsection may direct the applicant to pay to any person entitled to the benefit of the restriction such sum by way of consideration as the Tribunal may think it just to award under one, but not both, of the following heads, that is to say, either – (i) A sum to make up for any loss or disadvantage suffered by that person in consequence of the discharge or modification; or …. (1A) Subsection (1)(aa) above authorises the discharge or modification of a restriction by reference to its impeding some reasonable user of land in any case in which the Upper Tribunal is satisfied that the restriction, in impeding that user, either – (a) does not secure to persons entitled to the benefit of it any practical benefits of substantial value or advantage to them; or (b) …..; and that money will be an adequate compensation for the loss or disadvantage (if any) which any such person will suffer from the discharge or modification. (1B) In determining whether a case is one falling within subsection (1A) above, and in determining whether (in any such case or otherwise) a restriction ought to be discharged or modified, the Upper Tribunal shall take into account the development plan and any declared or ascertainable pattern for the grant or refusal of planning permissions in the relevant areas, as well as the period at which and context in which the restriction was created or imposed and any other material circumstances.”
