Regina (A) v Director of Establishments of the Security Service
Supreme Court
“A challenge to the refusal to allow a former member of the Security Service to publish a book about his work on the ground that it violated the right to freedom of expression guaranteed by article 10 of the European Convention on Human Rights could only be brought before the Investigatory Powers Tribunal established by the Regulation of Investigatory Powers Act 2000. The High Court had no jurisdiction to hear such a matter against the intelligence services.”
