Section 433: Reference in difficult cases to scientific persons

(1)

(2)
A referee may be selected by an agreement between the Minister and the appellant, or in default of an agreement, by the Minister and the appeal shall be determined by a referee rather than by the Board of Survey.
(3)
If an appellant in any appeal requires the Minister to, and gives security to the satisfaction of the Minister to pay the costs of and incidental to a reference, the Minister shall refer the appeal to a referee selected as provided in subsection (2) of this section.
