284. Where a person appeals, or purports to appeal, under this Act—
(a) to the Tribunal; or
(b) against a determination or decision of the Tribunal to the Supreme Court, and it appears to the Tribunal or Court that—
(i) the appeal, or purported appeal, or the decision, or purported decision, against which the appeal, or purported appeal, has been brought is affected by a failure to comply with a requirement of this Act; and
(ii) to exercise the powers conferred by this subsection would not be unjust or inequitable;
the Tribunal or the Court may excuse the failure by ordering that, subject to such conditions as may be specified in the order by the Tribunal or the Court, the requirement concerned be dispensed with to the necessary extent.
