Lapse of permission

Every permission granted under section 31 or section 32 or section 33 shall remain in force for a period of three years from the date of such grant and thereafter it shall lapse: Provided that the Director may, on an application, extend such period from year to year but the total period shall, in no case exceed five years from the date on which the permission was initially granted: Provided further that such lapse shall not bar any subsequent application for fresh permission under this Act.
