Sections 19 to 21 – Disclosure of information and the intelligence services
60.Section 19 provides that any person may give information to any of the intelligence services (defined in section 21 as the Security Service, the Secret Intelligence Service, and the Government Communications Headquarters) for the purpose of any of the functions of that service. The provisions that specify the functions of each of the intelligence services are listed in section 21(2). The person giving the information may do so regardless of any duty to keep the information confidential or of any other restriction on disclosure (subsection (6)). This is subject the Data Protection Act 1998 and Part 1 of the Regulation of Investigatory Powers Act 2000 (see section 20(2)).
61.Subsection (2) provides that information obtained by an intelligence service in connection with one of its functions may be used by it in connection with any of its other functions. Subsections (3) to (5) govern the disclosure of information obtained by the intelligence services for the purposes of any of its functions. Such information may be disclosed by the service for the purpose of the proper performance of any of its functions or for other the purposes specified in those subsections (which include for each organisation the purpose of any criminal proceedings). Again, such a disclosure will not breach any obligation of confidentiality or other restriction (subsection (6)), subject to compliance with the Data Protection Act and Part 1 of the Regulation of Investigatory Powers Act 2000 (section 20(2)).
62.Section 20 makes it clear that the information sharing provisions in section 19 do not affect the duties on the heads of the intelligence services (listed in subsection (1)) to ensure that arrangements are in place for securing that their service obtains and discloses information only in accordance with the purposes specified in the provisions listed in that subsection (which mirror the purposes listed in section 19(3) to (5)).
