law: 350. Supplemental provisions regarding bye-laws and regulations.
  (1) Any power to make bye-laws conferred by this Act is conferred subject to the conditions of bye-laws being made after previous publication and of their not taking effect until they have been approved and confirmed by the Central Government and published in the Official Gazette.
  (2) The Central Government in confirming a bye-law may make any change therein which appears to it to be necessary.
  (3) The Central Government may, after previous publication of its intention, cancel any bye-law which it has confirmed, and thereupon the bye-law shall cease to have effect.
  (4) Every bye-law and Regulation made under this Act and every order made under sub-section (3) 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 bye-law and Regulation, or order or both Houses agree that the bye-law and Regulation, or order should not be made, the bye-law and Regulation, or 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 bye-law and Regulation or order.
