In its December 2014 ruling, the Investigatory Powers Tribunal found that the legislative framework in the United Kingdom does not permit mass surveillance and that while GCHQ collects and analyses data in bulk, it does not practice mass surveillance. A report on Privacy and Security published by the Intelligence and Security Committee of Parliament also came to this view, although it found past shortcomings in oversight and said the legal framework should be simplified to improve transparency. This view is supported by independent reports from the Interception of Communications Commissioner. However, notable civil liberties groups continue to express strong views to the contrary and plan to appeal the ruling to the European Court of Human Rights, while others have criticised these viewpoints in turn.
