“Unique expertise in the fields of interception and surveillance.”

Legal 500

BCL’s knowledge of surveillance and interception law is unrivalled, drawing on the outstanding experience of the former Director of Legal Affairs at GCHQ, Michael Drury. The main focus of the team’s work is the UK’s complex investigatory powers legislation and associated Codes of Practice laws which govern access to electronic and other information by law enforcement authorities and the security services.

Our advisory work often involves consideration of the Intelligence Services Act 1994, the Police Act 1997, the Regulation of Investigatory Powers Act 2000, the Wireless Telegraphy Act 2006, the Investigatory Powers Act 2016 and its secondary legislation, and applicable data protection legislation.

Additionally, we advise domestic and US ‘covered providers’ on their obligations under the UK-US Data Sharing Agreement reached in 2019, as well as on related provisions of the Crime (Overseas Production Orders) Act 2019 and the applicable Criminal Procedure Rules.

Our work encompasses voluntary disclosure of information to law enforcement agencies using the ‘information sharing gateways’ in the Counter Terrorism Act 2008 and Crime and Courts Act 2013, as well as challenges brought in the Investigatory Power Tribunal to the unlawful exercise of surveillance and interception powers by state authorities, including breaches of the Human Rights Act 1998 / Convention rights.

We also provide prospective advice with regard to forthcoming legislative developments relating to surveillance and interception law, as well as on the implications of judicial decisions by domestic and overseas courts on the legality of state activity in this highly specialist field.
