(2)Notwithstanding any judgment or order of any Court, all proceedings taken for the grant of, and all orders passed granting any variation, extension or curtailment of the route or routes or the area specified in a stage carriage permit before the commencement of this Act by the State Transport Authority or by a Regional Transport Authority or by an authority or person to whom the powers and functions of the State Transport Authority or a Regional Transport Authority have been delegated, or by an authority exercising the powers of appeal or revision against the orders of the State Transport Authority or a Regional Transport Authority, shall not be deemed to, be invalid merely by reason of the fact that the State Transport Authority or the Regional Transport Authortiy, as the case may be, had no power to grant such variation, extension or curtailment and all such proceedings taken or orders passed shall be deemed always to have been validly taken or passed in accordance with law notwithstanding the distance covered by the variation or extension exceeded twenty four kilometers." The learned counsel for the respondent contends that section 4 8 3 (xxi), as amended, operates whether a condition to that effect has been put in a permit or not.
