Limitation for filing appeal: timelines govern appeals against listing refusals, omitted disposals, and prolonged suspensions; tribunal may extend. Appeals against a recognised stock exchange's refusal to list or its omission/failure to dispose of an application must be brought to the Securities Appellate Tribunal within prescribed short periods from receipt of reasons or from expiry of the specified time; the Tribunal may on sufficient cause allow a further limited extension. Separately, appeals against withdrawal or prolonged suspension of admission to dealings in securities or units of a collective instrument scheme must be filed within a prescribed period from receipt of the order, subject to the Tribunal's discretion to admit delayed appeals for sufficient cause.
