The authorities intercepted telephone conversations on card phones used by prisoners with people outside the prison. Was the intercepted material admissible? Was it a ‘communication in the course of its transmission . . by means of a public telecommunications system’ ? The lines came into the prison from the BT network. They ran to a control room in which there was a box which contained an isolator switch for each line. The isolator switch could be operated by prison officers to activate or deactivate each line. A recording device was attached to each line and all calls were automatically recorded as soon as a card phone handset was lifted from the rest position. The prisoner used a card to make a phone call.
Held: It was of central importance to determine whether the calls were being transmitted by a public telecommunication system at the time and place of interception. It was a private system at the point of interception, and the intercept was admissible.
