law: 13. Power to remove difficulties.-
  (1) If any difficulty arises in giving effect to the provisions of this Act, the Central Government may, by order notified in the Official Gazette, make such provision, not inconsistent with the provisions of this Act, as appears to it to be necessary or expedient for the removal of the difficulty:
  Provided that no such order shall be made after the expiry of a period of two years from the appointed day.
  (2) Every order made under this section 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 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 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.
