(1) Where an enactment confers any jurisdiction on a court or other tribunal or extends or varies any such jurisdiction, the authority having power to make rules or orders regulating the practice and procedure of that court or tribunal may make such rules or orders (including rules or orders regulating costs, fees and witnesses' and other expenses) as appears to the authority to be necessary for regulating the practice and procedure of that court or tribunal in the exercise of the jurisdiction so conferred, extended or varied, and it shall not be necessary for any other enactment to confer power on the authority to make any rules or orders for these purposes.

(b) prescribes or alters court fees;
but the validity of any rule or order made by such an authority shall not in any proceedings in any court or tribunal be impugned either by the court or tribunal or by any party to the proceedings on the ground only that such concurrence as aforesaid has not been given or is not expressed to have been given.
(3) All rules or orders made under any enactment and regulating the practice or procedure, or costs, fees or expenses, of any court or tribunal and in force at the commencement of this Act shall be deemed to have been made under this section and may be varied or revoked accordingly.
