The International Airports Authority Act 1971
40. Power to remove difficulties
(1) If any difficulty arises in giving effect to the provisions of this Act, the Central Government may, by general or special order published in the Official Gazette, make such provisions not inconsistent with the provisions of this Act as appear to it to be necessary or expedient for the removal of the difficulty :
Provided that no such order shall be made after the expiration of one year from the commencement of this Act.
(2) Every order made under sub-section (1) shall be laid, as soon as may be after it is made, 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 successive sessions and if before the expiry of the session in which it is so laid or the session immediately following both Houses agree in making any modification in the order or both Houses agree that the order should not be made, the order 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 order.
