• (a) that that person has applied in writing to the proprietor for a written acknowledgment to the effect of the declaration or declarator claimed, and has furnished him with full particulars in writing of the act in question; and
• (b) that the proprietor has refused or failed to give any such acknowledgment.

(2) Subject to section 72(5) below, a declaration made by the comptroller under this section shall have the same effect as a declaration or declarator by the court.
