(1) If the Central Government is satisfied that circumstances have arisen rendering it necessary that any permission granted or restriction imposed by this Act should cease to be granted or imposed, or if it considers necessary or expedient so to do in public interest, the Central Government may, by notification, suspend or relax to such extent either indefinitely or for such period as may be notified, the operation of all or any of the provisions of this Act.

(2) Where the operation of any provision of this Act has under sub-section (1) been suspended or relaxed indefinitely, such suspension or relaxation may, at any time while this Act remains in force, be removed by the Central Government by notification.

(3) Every notification issued under this section shall be laid, as soon as may be after it is issued, before each House of Parliament, while it is in session, for a total period of thirty days which may be comprised in one session or in two or more successive sessions, and if, before the expiry of the session immediately following the session or the successive sessions aforesaid, both Houses agree in making any modification in the notification or both Houses agree that the notification should not be issued, the notification shall thereafter have effect only in such modified form or be of no effect, as the case may be; so, however, that any such modification or annulment shall be without prejudice to the validity of anything previously done under that notification.
