Development of Rural Wales Act 1976

25 (1) If a person aggrieved by a compulsory purchase order, or by a certificate under paragraph 15 above, desires to question the validity thereof, or of any provision contained therein, on the ground that it is not within the powers conferred by the new towns code or that any requirement of that code or of any regulation made thereunder has not been complied with in relation to the order or certificate, he may, within six weeks from the date on which notice of the confirmation or making of the order or of the giving of the certificate is first published in accordance with the foregoing provisions of this Part of the new towns code in that behalf, make an application to the High Court.

(2) The High Court, on such an application—

(a) may by interim order suspend the operation of the order or any provision contained therein or of the certificate, either generally or in so far as it affects the property of the applicant, until the final determination of the proceedings; and

(b) if satisfied that the order or any provision contained therein, or the certificate, is not within the powers conferred by the new towns code or that the interests of the applicant have been substantially prejudiced by any requirement of that code or of any regulation made thereunder not having been complied with, may quash the order or any provision contained therein, or the certificate, either generally or in so far as it affects any property of the applicant.
