Publication of rules requires Gazette notice and laying before legislature for review, with power to modify or annul. All rules and notifications under the Act must be published in the Official Gazette. Specified rules, notifications and orders (except those of strategic, secret, individual or personal nature) must be laid before Parliament or the State Legislature for a cumulative thirty days in session(s). The legislature may modify or annul such instruments within the prescribed period, and any modification or annulment does not impair the validity of actions previously taken under them.
