" We may now refer to the two sections, Central section 64A and Bihar section 64A : "Central section 64A : The State Transport Authority may, either on its motion or on an application made to it, call for the record of any case in which an order has been made by a Regional Transport Authority and in which no appeal lies, and if it appears to the State Transport Authority that the order made by the Regional Transport Authority is improper or illegal, the State Transport Authority may pass such order in relation to the case as it deems fit : Provided that the State Transport Authority shall not entertain any application from a person aggrieved by an order of a Regional Transport Authority, unless the application is made within thirty days from the date of the order: Provided further that the State Transport Authority shall not pass an order under this section prejudicial to any person without giving him a reasonable opportunity of being heard." "Bihar section 64A : The State Government may, on application made to it in this behalf, within thirty days of the passing of the order in the course of any proceedings taken under this Chapter by any authority or officer subordinate to it, call for the records of such proceedings, and after examining such records pass such order as it thinks fit.
