269Right of appeal against order.
(1)A person aggrieved by a demolition or closing order may, within 21 days after the date of the service of the order, appeal to the county court.
(2)No appeal lies at the instance of a person who is in occupation of the premises under a lease or agreement with an unexpired term of three years or less.
(3)On an appeal the court—
(a)may make such order either confirming or quashing or varying the order as it thinks fit, and
(b)may, if it thinks fit, accept from an appellant any undertaking which might have been accepted by the local housing authority.
(4)The court shall not accept an undertaking to carry out works from an appellant on whom a notice was served under section 264(1) (notice of appointment to consider condition of premises) unless the appellant complied with the requirements of section 264(3) (duty to give notice of intention to offer undertaking and to supply list of works).
(5)An undertaking accepted by the court has the same effect as an undertaking given to and accepted by the local housing authority under section 264.
(6)If an appeal is brought the order does not become operative until—
(a)a decision on the appeal confirming the order (with or without variation) is given and the period within which an appeal to the Court of Appeal may be brought expires without any such appeal having been brought, or
(b)if a further appeal to the Court of Appeal is brought, a decision on that appeal is given confirming the order (with or without variation);
and for this purpose the withdrawal of an appeal has the same effect as a decision confirming the order or decision appealed against.
