17(1)So soon as may be after the Commission have received from a Regional Valuation Board certificates sent by them under the last preceding paragraph, the Commission shall publish in one or more newspapers circulating in the valuation region a notice to the effect that certificates relating to that region have been sent to them under that paragraph, and naming a place where the certificates may be seen at all reasonable hours by any person having an acquired interest comprised in a holding in that region or a successor in title of any such person.
(2)If any person aggrieved desires to question the validity of any certificate relating to a valuation region in respect of which a notice has been published by the Commission under the preceding sub-paragraph, or the propriety of the omission from the certificates sent in relation to that region of a certificate relating to any holding, on the ground that any requirement of this Act or of the Registration Act or of any rules made under either of them has not been complied with, he may, within six weeks after the first publication of the notice, make an application for the purpose to the High Court, and, where any such application is duly made, the Court—
(a)may by interim order direct the Commission to suspend the payment of compensation on the basis of the certificates sent; and
(b)if satisfied upon the hearing of the application that the interests of the applicant have been substantially prejudiced by any such requirement as aforesaid not having been complied with, may quash a certificate relating to any holding that appears to the Court to be affected, and give such directions as appear to the Court to be requisite for remedying the default and enabling the giving of valid certificates as respects all holdings in the valuation region for which compensation is payable to be completed.
(3)Subject as aforesaid the amounts specified in certificates relating to a valuation region in respect of which such a notice as aforesaid has been published shall be deemed to have been properly certified for the purposes of subsection (7) of section seven of this Act, and the holdings to which the certificates relate shall be deemed for those purposes to be the holdings in that region for which compensation is payable, and the right of the Commission to make payments on the basis of such certificates shah not, after the expiration of the said period of six weeks, be questioned by prohibition or certiorari or in any other legal proceedings whatsoever.
