Stay extension provision allows appellate tribunal to extend provisional stay where delay is not attributable to a party. The amendment authorises the Appellate Tribunal, on application and if delay is not attributable to the applicant, to extend the period of stay for a further period not exceeding one hundred and eighty-five days, but provides that if the appeal remains undisposed within a total period of three hundred and sixty-five days from the date of the order in the first proviso, the stay shall stand vacated upon expiry of that total period.
