Information Section 38: Disclosure of information for security purposes
88.Section 38 introduces a discretionary power which supports the disclosure of information relating to travel or freight for security purposes and defines the actors and purposes to whom the provision applies.
89.The section provides that the Secretary of State in so far as he has functions under the Immigration Acts, a chief officer of the police and HM Revenue and Customs may disclose information which is obtained or held by them in the course of their functions to the Security and Intelligence Agencies (SIAs) to the extent that the information is likely to be of use for a purpose specified in section 1 of the Security Service Act 1989 and sections 1 or 3 of the Intelligence Services Act 1994 (namely, national security, economic well being of the UK and support in combating serious crime).  It is not necessary to provide for a reciprocal power for the provision of data by the SIAs to the Border Agencies because such disclosures, where necessary, may be made on the basis of existing legislation.
90.The Secretary of State and the Treasury will specify jointly by order the information that may be disclosed.  Subsection (6) clarifies that the powers specified jointly by the Secretary of State and the Treasury do not apply to information collected by HM Revenue and Customs under the former Inland Revenue's powers.
