Appeal filing deadline set from receipt of exchange order; tribunal may condone delay for sufficient cause. A new sub rule requires that appeals against a recognised stock exchange order withdrawing or suspending admission to dealings that continues beyond three months in any security, units or other instruments of a 'collective instrument scheme' be filed within forty five days from receipt of a copy of the order; the Appellate Tribunal may entertain an appeal after that period if satisfied there was sufficient cause for not filing within that period.
