Part 1: Call-in for national security Chapter 4: Procedure Section 19: Power to require information
Section 19 provides for investigatory powers which enable the Secretary of State to obtain information either before or after the call-in power is exercised. The information must relate to the exercise of the Secretary of State’s functions under the Act. Information may be required, for example, in order to determine whether a call-in notice should be given or whether remedies should be imposed.
	Subsection (2) provides a proportionality test for use of this power.
	Subsection (4) provides that the Secretary of State may specify in the notice the manner in which information is to be provided and the time limit for providing it. The time limit for providing information may depend on the type of information and the amount of time required to obtain it. Subsection (4)(c) enables the Secretary of State to require the person to provide any information within their possession or power which would enable the Secretary of State to find the information required by the notice.
