Part 1: Call-in for national security Chapter 1: Call-in power Section 4: Consultation and parliamentary procedure
Section 4 sets out the procedure that must be followed before the Secretary of State is able to publish the statement about the exercise of the call-in power. Before the statement may be published, the Secretary of State must carry out such consultation as the Secretary of State thinks appropriate in relation to a draft of the statement, make any changes to the draft that appear to the Secretary of State to be necessary in view of the responses to the consultation, and lay the statement before Parliament, where it is subject to annulment by either House within a period of 40 sitting days.
	Subsections (2) to (4) provide that either House of Parliament may annul a statement before the expiry of the 40 sitting day limit. The consequence of the annulment is that the statement must be withdrawn. The annulment of a statement does not affect the validity of any call-in notice given prior to its withdrawal, nor does it affect the publication of a new statement.
