Commentary on Sections Powers: supplementary Section 35: Code: effect
87.Failure by a police officer or a member of the armed forces to comply with any part of a code of practice does not make them liable to civil or criminal proceedings, with the exception for armed forces personnel of proceedings under the Army Act 1955, Air Forces Act 1955 and Naval Discipline Act 1957 (but not civil offences under those Acts). A code is admissible as evidence in criminal and civil proceedings, and must be taken into account by a court or tribunal where the code appears relevant.
