Liberal Conspiracy. The only regular press coverage of this decision I can find is the
Sunday Business Post in Ireland (the original case was in Northern Ireland):
The state is allowed to bug communication between lawyers and their clients, the House of Lords has said. The UK's highest court ruled that spy law the Regulation of Investigatory Powers Act (RIPA) allows lawyers' conversations to be bugged.
Lawyers are allowed to withhold the details of communication with their clients from the police, prosecutors or courts. This long-established right is designed to allow a client to receive full and proper legal advice. Under legal professional privilege they can tell their lawyer the full facts of a situation without fear of the communications ending up as evidence against them.
RIPA is the law which governs secret surveillance, outlining what the state can and cannot do to obtain information.
...
Lord Carswell also said that the Code explaining RIPA suggests that the law does cover privileged communication.
"The Code makes detailed provision for obtaining authorisation for monitoring consultations covered by legal professional privilege," he said. "It was laid before and approved by Parliament, but no point appears to have been taken that RIPA did not cover such consultations. It would be surprising at least that no objection was made to the inclusion of those provisions in the Code if it was thought that Parliament had not intended that the consultations be covered by RIPA."
