From EPIC.org:
Human rights organizations have appealed a judgment concerning GCHQ spying to the European Court of Human Rights. Liberty first challenged the GHCQ in case before the UK Investigative Powers Tribunal. The Tribunal ruled in December that the GCHQ complied Article 8 of the European Convention on Human Rights, but in February 2015 the Tribunal held that the oversight rules were not made accessible to the public as required by Article 8.
