For nearly two decades, British spies unlawfully maintained vast troves of people’s private data without adequate safeguards against misuse, a tribunal of senior judges has ruled. Between 1998 and 2005, electronic surveillance agency Government Communications Headquarters and domestic spy agency MI5 began secretly harvesting “bulk personal datasets” containing millions of records about people’s phone calls, travel habits, internet activity, and financial transactions. On Monday, the Investigatory Powers Tribunal, a special court that handles complaints related to British spy agencies, found that access to the datasets had not been subject to sufficient supervision through a 17-year period between 1998 and November 2015. The tribunal said that due to “failings in the system of oversight” the surveillance regime had violated Article 8 of the European Convention on Human Rights, which protects the right to privacy.
