Housing Act 1957

2 If any person aggrieved by such an order as aforesaid, or by the Minister's approval of a re-development plan or of a new plan, desires to question the validity thereof on the ground that it is not within the powers of this Act or that any requirement of this Act has not been complied with, he may, within six weeks after the publication of the notice of confirmation of the order, or of the approval of the plan, make an application for the purpose to the High Court, and where any such application is duly made the court—

(i) may by interim order suspend the operation of the order, or the approval of the plan, either generally or in so far as it affects any property of the applicant until the final determination of the proceedings ; and

(ii) if satisfied upon the hearing of the application that the order, or the approval of the plan, is not within the powers of this Act or that the interests of the applicant have been substantially prejudiced by any requirement of this Act not having been complied with, may quash the order, or the approval of the plan, either generally or in so far as it affects any property of the applicant.
