FOIA Section 23 Exemption

Section 23: Information Supplied by, or Related to, Bodies Dealing with Security Matters

Section 23 exempts information received from, or related to, the security bodies listed at section 23(3) of the Freedom of Information Act. This includes the Security Service, the Secret Intelligence Service, Government Communications Headquarters and the Serious Organised Crime Agency. Key points: It will often be appropriate to 'neither confirm nor deny' that the requested information is held, as the fact that a public authority does or does not hold information supplied by one of the security bodies can itself be information relating to those bodies. The interaction between section 23 and section 24 (national security) is complex and needs to be considered carefully in order to ensure that the relevant public interests are protected. Section 23 is not subject to any public interest test. A ministerial certification procedure exists where it becomes necessary to rely on this exemption.
