Original Legislation Officers of port police forces are sworn in as "special constables" under section 79 of the
Harbours, Docks and Piers Clauses Act 1847, as a result, officers have the full powers of a constable on any land owned by the harbour, dock, or port and at any place within one mile of any owned land. (The act uses the term 'special constable'; at the time this act was passed 'special constable' meant any constable who was not a member of a territorial police force).
Additional Powers The
Marine Navigation Act 2013 has potentially enabled ports constables in England & Wales to act as constables beyond this one mile limit, in relation to policing purposes connected with the port only, in a police area where consent has been obtained from the relevant
chief constable. This act does
not however give general police powers to ports constables, beyond their core jurisdiction as set out in the 1847 act, merely in relation to policing purposes connected to the port as set out in the Act. As of 2014, three ports police forces (
Dover,
Teesport and Bristol) have sought and received consent from the local chief constable. This has enabled PoB Police Constables, in relation to policing purposes connected to the port, to act as such, throughout the police area in which they are geographically located. Serious or major incidents or crime generally become the responsibility of territorial police force;
Avon and Somerset Constabulary. ==Multi-agency approach==
