Parliamentary scrutiny of delegated legislation: rules and specified notifications must be laid and may be modified or annulled. Every rule under the Act and every notification under sub-clause (iv) of clause (23C) of section 10 must be laid before each House of Parliament for a total of thirty days across one or more sessions; if, before the end of the session immediately following that period, both Houses agree to modify or annul the rule or notification, it will take effect only as modified or be of no effect, subject to preservation of the validity of actions previously done under it.
