UK secret service MI5 accused of ‘persistent illegality’ by mass data collection based on false information
- High Court in London heard that warrants were issued to MI5 for reasons the service knew to be incorrect and judicial watchdogs given false information
MI5 has lost control of its data storage operations and has been obtaining surveillance warrants on the basis of information it knows is false, Britain’s High Court has heard.
The security agency has been accused of “extraordinary and persistent illegality” in a legal challenge brought by human rights organisation Liberty.
The failures have been identified by the official watchdog, Investigatory Powers Commissioner Adrian Fulford, and admitted in outline by Home Secretary Sajid Javid.
The full extent of the problems within MI5 began to become apparent in disclosures made public at the hearing on Tuesday. The revelations relate to bulk interceptions of data acquired through surveillance and hacking programmes and downloaded to its computers.
The agency has a duty to ensure such material is not held longer than required or copied more often than needed.
Ben Jaffey, counsel for Liberty, said there were “ungoverned spaces” in MI5’s operations where it did not know what it held.
