-
(b) remit the appeal or any matter arising thereon to the original tribunal with such declarations or directions as the appellate court may think proper;
-
(c) make such order as to costs and expenses as the appellate court may think proper, and—
-
(i) it shall be the duty of the original tribunal to have regard to all such declarations and to obey all such directions, if any, as may be given by the appellate court pursuant to paragraph (b), and
-
(ii) orders made by the appellate court shall have the like effect and may be enforced in like manner as orders made by the original tribunal.
