Stating the exemption

Section 30 of the Freedom of Information Act provides that:

  1. Information held by a public authority is exempt information if it has at any time been held by the authority for the purposes of -
    • (a) any investigation which the public authority has a duty to conduct with a view to it being ascertained: -
      • (i) whether a person should be charged with an offence, or
      • (ii) whether a person charged with an offence is guilty of it,
    • (b) any investigation which is conducted by the authority and in the circumstances may lead to a decision by the authority to institute criminal proceedings which the authority has power to conduct, or
    • (c) any criminal proceedings which the authority has power to conduct.
  2. Information held by a public authority is exempt information if -
    • (a) it was obtained or recorded by the authority for the purposes of its functions relating to -
      • (i) investigations falling within subsection (1)(a) or (b),
      • (ii) criminal proceedings which the authority has power to conduct,
      • (iii) investigations (other than investigations falling within subsection (1)(a)) which are conducted by the authority for any of the purposes specified in section 31(2) and either by virtue of Her Majesty's prerogative or by virtue of powers conferred by or under any enactment, or
      • (iv) civil proceedings which are brought by or on behalf of the authority and arise out of such investigations, and,
    • (b) it relates to the obtaining of information from confidential sources.
  3. The duty to confirm or deny does not arise in relation to information which is (or if it were held by the public authority would be) exempt information by virtue of subsection (1) or (2).
  4. In relation to the institution or conduct of criminal proceedings or the power to conduct them, references in subsection (1)(b) or (c) and subsection (2)(a) to the public authority include references -
    • (a) to any officer of the authority;
    • (b) in the case of a government department other than a Northern Ireland department, to the Minister of the Crown in charge of the department, and
    • (c) in the case of a Northern Ireland department, to the Northern Ireland Minister in charge of the department.
  5. (5) In this section -

    • (c) for any reference to a person being charged with an offence there is substituted a reference to the person being prosecuted for the offence.

1.1 General Points: explanation of key terms

1.1.1 The term charged:

This would include:

(These provisions of the Criminal Justice Act 2003 have not yet been brought into force.)

1.1.2 Powers of public authorities

Subsection (4) explains that the references in this section to public authorities' powers to conduct criminal proceedings, needs to be taken to include both individual officers of the authority and, in the case of government departments, ministers. This is necessary because, as is often the case, the power to prosecute is sometimes specifically vested in a particular office-holder within the authority rather than in the authority generally. For example, certain powers to prosecute are given to inspectors appointed under section 19 of the Health and Safety at work etc. Act 1974, rather than, say, to the HSE as the relevant public authority.

1.1.3 The term criminal proceedings

Section 30(5) defines criminal proceedings to include proceedings before courts-martial and Courts Martial Appeals Courts, and proceedings involving charges brought under various pieces of armed forces legislation as defined in the section, as well as criminal proceedings before civilian criminal courts in the United Kingdom.
