"(1) A tribunal may at any time before the hearing of an originating application, on the application of a party made by notice to the Secretary or of its own motion, conduct a pre-hearing review, consisting of a consideration of-- (a) the contents of the originating application and notice of appearance; (b) any representations in writing; and (c) any oral argument advanced by or on behalf of a party."
"If upon a pre-hearing review the tribunal considers that the contentions put forward by any party in relation to a matter required to be determined by a tribunal have no reasonable prospect of success, the tribunal may make an order against that party requiring the party to pay a deposit of an amount not exceeding£150 as a condition of being permitted to continue to take part in the proceedings relating to that matter."
