law: Pension’s Act, 1871
  16. Laying of Rules
  Every rule made by the Central Government under this Act and
  
  every rule made under section 14 by a Chief Controlling Revenue Authority with
  
  the consent of the Central Government, 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 rule or both Houses agree that the rule
  
  should not be made, the rule 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 rule.]
