10(1)In the case of each holding in respect of which an application for the registration of particulars has been duly made under the Registration Act and a notice of claim for compensation has been duly served, the Commission shall, as soon as may be after the registration of particulars in respect thereof has been effected, give notice thereof to the Regional Valuation Board:
Provided that—
(a)in a case in which registration in respect of a holding has been effected before the expiration of the period during which notice may be given under paragraph 8 of this Schedule, the Commission shall not give notice of the registration under this paragraph until that period has expired or, where any notice is given under that paragraph, until the proceedings consequent thereon have been completed; and
(b)the Commission shall not in the case of any holding give notice of registration under this paragraph if it appears to the Commission that there is any error or omission that renders the particulars registered in respect thereof open to objection, or that any such error or omission is likely to appear from proceedings still to be taken in connection with the registration of particulars in respect of another holding.
(2)When the Commission give notice of registration under this paragraph in relation to any holding, they shall serve a copy of the notice on the claimant, and also on the following persons, that is to say, the person, if other than the claimant, by whom the application for registration was made, any person entitled under sub-paragraph (2) (a) of paragraph 2 of the Second Schedule to the Registration Act to be notified of the application, and any other person by whom a notice has been given to the Commission under paragraph 8 of this Schedule (who are hereinafter in this Schedule referred to as " persons intervening ").
(3)The valuation of a holding shall be made on the basis of the particulars registered in respect thereof on the date on which notice of registration is given to the Regional Valuation Board in relation thereto under this paragraph, and as from that date the provisions of the Registration Act with respect to the rectification of the register shall cease to have effect in relation to the holding :
Provided that, if from any information in the possession of the Regional Valuation Board it appears to them that there is in the particulars so registered as aforesaid an error or omission of material importance for valuation purposes, they may, at any time before they have settled their draft valuation of the holding, notify the Commission that they are of that opinion and thereupon the said provisions shall again come into effect, and, if any alteration is made thereunder in the particulars so registered as aforesaid, the valuation shall be made on the basis of the particulars as altered.
(4)The particulars registered in respect of a holding on the date on which notice of registration is given to the Regional Valuation Board in relation thereto under this paragraph, or, in the case of particulars that are altered after that date under the proviso to the last preceding sub-paragraph, those particulars as so altered, shall be assumed conclusively to be correct and complete for the purposes of the valuation of the holding, and shall also, as against the estate owner in respect of the holding and all persons claiming under him and their successors in title respectively be assumed prima facie to be correct and complete for the purpose of ascertaining the premises that vest in the Commission on the vesting date and the title for which they so vest, but the inclusion therein, or the omission therefrom, of any matter shall not be treated as affecting any right or liability, or as binding on any person, for any other purpose.
(5)The estate owner in respect of a holding, in respect of which the payment of compensation under this Act is claimed, and all persons claiming under him and their successors in title respectively shall be estopped from asserting after the vesting date any matter adversely affecting the premises in which the holding subsisted, unless it is shown that there was furnished for the purposes of the Registration Act information of all the circumstances of the holding relevant to that matter, or, if it was a matter with respect to which the Commission or the Board of Trade gave such an indication as to the information material in their opinion for valuation purposes as is mentioned in section thirty-six of this Act, such information with respect to that matter as was thereby indicated.
