Section 13. Power to make rules

13. (1) The State Government may, subject to the condition of previous
publication, make rules, by notification, with prospective or
retrospective effect, for carrying out the purposes of this Act:
Provided that if the State Government is satisfied that
circumstances exist which render it necessary for it to take
immediate action, if any, it may make any rules without such
previous publication.
(2) All rules made by the State Government under this Act shall, as
soon as may be, after they are made, be laid before the State
Legislature while it is in session for a total period of not less
than fourteen days which may be comprised in one session or
two or more successive sessions, and shall, unless some later
date is appointed, take effect from the date of their publication in
the Official Gazette subject to such modifications or annulments
as the Legislature may, during the said period agrees to make, so
however, that any such modification or annulment shall without
prejudice to the validity of anything previously done thereunder.
