Laying of rules, regulations and notifications

166. Every rule made by the Government, every regulation made by the Government and every notification issued by the Government under this Act, shall be laid, as soon as may be after it is made or issued, before the State Legislature, 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, the State Legislature agrees in making any modification in the rule or regulation or in the notification, as the case may be, or the State Legislature agrees that the rule or regulation or the notification should not be made, the rule or regulation or notification, as the case may be, 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 or regulation or notification, as the case may be.
