Provided that where such appeal is not so disposed of within the said period of  stay as specified in the order of stay, the Appellate Board may, on an application made in this behalf by the dealer and on being satisfied that the delay in disposing of the appeal is not attributable to the dealer, extend the period of stay, or pass an order of stay for a further period or periods as it thinks fit; so, however, that the aggregate of the period originally allowed and the period or periods so extended or allowed shall not, in any case, exceed three hundred and sixty-five days and the Appellate Board shall dispose of the appeal within the period or periods of stay so extended or allowed :

Provided further that if such appeal is not disposed of within the period allowed under this sub-section or the period or periods extended or allowed under the first proviso, which shall not, in any case, exceed three hundred and sixty-five days, the order of stay shall stand vacated after the expiry of such period or periods, even if the delay in disposing of appeal is not attributable to the dealer.

(4) The cost, if any, in an appeal shall be at the discretion of the Appellate Board. 

(5) The Appellate Board shall send a copy of any orders passed under this section to the dealer and to the Commissioner.
