The Investigatory Powers Tribunal, a judicial oversight body for the intelligence agencies, ruled in December 2014 that the legislative framework in the United Kingdom does not breach the European Convention on Human Rights. However, the Tribunal stated in February 2015 that one particular aspect, the data sharing arrangement that allowed UK Intelligence services to request data from the US surveillance programs Prism and Upstream, had been in contravention of human rights law prior to this until two paragraphs of additional information, providing details about the procedures and safeguards, were disclosed to the public in December 2014.
