Parliament – Member. The present judgment concerned the hearing of preliminary issues relating to the status, meaning and effect of the Wilson Doctrine, to the effect that there was to be no tapping of the telephones of Members of Parliament. The Investigatory Powers Tribunal gave guidance on its application with respect to s 8(1) and (4) of the Regulation of Investigatory Powers Act 2000, and held that the doctrine was not legally enforceable and that the regime for interception complied with the European Convention on Human Rights.
