(1) If the applicant is aggrieved by the decision of the local planning authority to refuse listed building consent or conservation area consent for the proposed works, or to grant consent subject to conditions, he may appeal to the [Secretary of State for the Environment] [Secretary of State for Wales] in accordance with sections 20 and 21 of the Planning (Listed Buildings and Conservation Areas) Act 1990 within six months of receipt of this notice. (Appeals must be made on a form which is obtainable from the [Department of the Environment] [Welsh Office]). The Secretary of State has power to allow a longer period for the giving of a notice of appeal but he will not normally be prepared to exercise this power unless there are special circumstances which excuse the delay in giving notice of appeal.
(2) If listed building consent or conservation area consent is refused, or granted subject to conditions, whether by the local planning authority or by the [Secretary of State for the Environment] [Secretary of State for Wales], and the owner of the land claims that the land has become incapable of reasonably beneficial use in its existing state and cannot be rendered capable of reasonably beneficial use by the carrying out of any works which have been or would be permitted, he may serve on the council of the district, or London borough in which the land is situated (or, where appropriate, on the Common Council of the City of London) a purchase notice requiring that council to purchase his interest in the land in accordance with the provisions of section 32 of the Planning (Listed Buildings and Conservation Areas) Act 1990.
(3) In certain circumstances a claim may be made against the local planning authority for compensation where permission is refused or granted subject to conditions by the Secretary of State on appeal or on a reference of the application to him. The circumstances in which such compensation is payable are set out in section 27 of the Planning (Listed Buildings and Conservation Areas) Act 1990.
