Parliamentary scrutiny of delegated legislation: instruments must be laid before both Houses and may be modified or annulled. Every rule under the Act, notifications under sub-section (1) of section 5A and section 11C, and orders under sub-section (2) of section 5A, other than orders relating to goods of strategic, secret, individual or personal nature, shall be laid before each House of Parliament for thirty days (which may span sessions), and if both Houses agree to modify or annul before the expiry of the following session, the instrument shall thereafter have effect only as modified or be of no effect; such modification or annulment does not affect the validity of past actions under the instrument.
