Part 5: Equipment interference Section 133: Section 132: meaning of "excepted disclosure"
This section provides that in certain situations the duty not to make an unauthorised disclosure in section 132 does not apply. Disclosures made in such circumstances are called "excepted disclosures". Excepted disclosures are grouped into 4 heads.
	Head 1 includes disclosure authorised by the warrant. It also includes disclosure which is necessary for the purpose of providing assistance in giving effect to a warrant. Head 2 allows for disclosure made to or authorised by a Judicial Commissioner, or a disclosure to the Independent Police Complaints Commission or the Intelligence and Security Committee of Parliament. Head 3 allows for disclosure in contemplation of, or in connection with, legal proceedings except where such a disclosure is made with the intention of furthering a criminal purpose. Head 4 allows for the disclosure of statistical information by a telecommunications operator, subject to any requirements imposed by regulations made by the Secretary of State, and for the disclosure of information by any person about warrants in general. This does not provide for disclosure of any particular warrant issued under Part 5.
