Subject to the provisions of this section, the Secretary of State shall, on application being made to him by any person, and may if he thinks fit without any such application, issue a certificate in the prescribed form with respect to any land stating whether any of that land had an original unexpended balance of established development value, and, if so—
Any such certificate issued with respect to any land may, if the Secretary of State thinks fit, contain additional information with respect to acts or events in consequence of which, in accordance with any of the preceding provisions of this Part of this Act, an amount is required to be deducted from the original unexpended balance of established development value of any of that land
Where, at any time on or after 1st January 1955 (whether before or after the commencement of this Act), a notice to treat has been served with a view to the compulsory acquisition of an interest in land by an authority possessing compulsory purchase powers, that authority may apply to the Secretary of State for, and shall be entitled to the issue of, a certificate showing the unexpended balance of established development value (if any) of any of that land immediately before the service of that notice.
Where the issue of a certificate under this section with respect to any land involves a new apportionment, or, in the case of a certificate under subsection (3) of this section, involves the calculation of a deduction from the original unexpended balance of established development value by virtue of section 141 of this Act, then—
Where by virtue of subsection (4)(c) or this section this subsection is to have effect, then—
Where, on a reference to the Lands Tribunal under this section, it is shown that a new apportionment relates partly to the same matters as a previous apportionment, and is consistent with that previous apportionment in so far as it relates to those matters, the Tribunal shall not vary the new apportionment in such a way as to be inconsistent with the previous apportionment in so far as it relates to those matters.
A certificate under subsection (3) of this section shall be conclusive evidence of the unexpended balance shown therein ; and a certificate under subsection (1) of this section shall be sufficient proof of any facts stated therein unless the contrary is shown.
An application for a certificate under this section shall be made in such form and manner as may be prescribed, and shall be accompanied by sufficient particulars, including a map if necessary, to enable the land to be identified, and, where a new apportionment will be involved, particulars of the nature of the applicant's interest, and such information as to the nature of any other interest in the land, and as to the name and address of the person entitled to that other interest, as may be known to the applicant.
On any application under subsection (1) of this section the applicant shall pay in the prescribed manner a fee of twenty-five new pence, and, if the application involves a new apportionment, the certificate shall not be issued until the applicant has paid in the prescribed manner a further fee of seventy-five new pence.
In this section "new apportionment "means an apportionment which relates wholly or partly to any matter to which no previous apportionment related.
