     Provided that if the notification under sub-section (1) is issued when Parliament is in session, such a Bill shall be introduced in Parliament during that session:
     Provided further that where, for any reason, a Bill as aforesaid does not become law within six months from the date of its introduction in Parliament, the notification shall cease to have effect on the expiration of the said period of six months, but without prejudice to the validity of anything previously done thereunder.
