Paragraph 10
If any person aggrieved by the order desires to question its validity 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 date on which notice of the confirmation of the order is published in accordance with the last foregoing paragraph, make an application for the purpose to the High Court; and if any such application is duly made the court, if satisfied that the order 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 either generally or in so far as it affects any property of the applicant; but except as aforesaid the order shall not at any time be questioned by prohibition or certiorari or in any proceedings whatsoever:
Provided that this paragraph shall not apply to an order which is confirmed by Act of Parliament under section six of the M1Statutory Orders (Special Procedure) Act 1945, and shall have effect in relation to any other order which is subject to special parliamentary procedure by virtue of paragraph 7 of this Schedule as if for the reference to the date of the publication of the notice there were substituted a reference to the date on which the order becomes operative under the said Act.
