"Any act other than the holding of a pre-hearing assessment under Rule 6, the hearing of an originating application or the making of an order under Rule 10(1), required or authorised by these Rules to be done by a tribunal may be done by, or on the direction of, the President or the chairman of the tribunal, or any chairman being a member of the panel of chairmen."
"A tribunal may at any time either upon the application of any person or, where appropriate, of its own motion, direct any person against whom any relief is sought to be joined as a party to the proceedings, and give such consequential directions as it considers necessary."

"Where it appears to the Appeal Tribunal that any proceedings were unnecessary, improper or vexatious or that there has been unreasonable delay or other unreasonable conduct in bringing or conducting the proceedings the Tribunal may order the party at fault to pay any other party the whole or such part as it thinks fit of the costs or expenses incurred by that other party in connection with the proceedings."
