Parliamentary scrutiny of subordinate legislation: rules and notifications may be annulled or modified within a subsequent session. Rules made under this Chapter and notifications under the Explanation to sub section (1) of section 35 or section 36 must be laid before each House of Parliament for a total period of thirty days across one or more sessions; if both Houses agree before the expiry of the immediately following session to annul or modify the rule or notification, it will thereafter have effect only as modified or be of no effect, without prejudice to the validity of anything previously done under it.
