Rupert Bowers KC was called to the Bar in 1995 and took silk in 2015. He was ranked as a leader in his field in the Chambers and Partners and Legal 500 publications before taking silk and has been ranked every year since being in silk.

Rupert leads the chambers Business Crime & Investigations team in Doughty Street maintaining a practice in financial crime and extradition, and data protection and information rights, with expertise in ancillary matters associated with criminal investigations and data breaches.

Rupert is one of the country’s leading experts in challenging search warrants of all types, seizures of property and information and in challenging asset freezing orders. He is one of only a few KC’s with experience not just of heavy trial and appellate work in the criminal courts, but with vast experience of judicial review and other applications in the civil courts. His breadth of knowledge across different jurisdictions is his strength. He was the only criminal silk in the case of Lucas v Security Service [2017] 1 All E.R. 283  (Click here) which challenged the lawfulness of the mass interception of communications data by GCHQ before the Investigatory Powers Tribunal (Click here), a case with many parallels with the recent transnational operation targeting the use of EncroChat. Rupert was instructed in the lead EncroChat case (Click here and here).

Rupert also practices in sports regulation and discipline which has included cases before the Court of Arbitration for Sport.

Rupert only acts for a small number of high net-worth private clients and companies at any one time which allows him to focus on their particular needs, and when involved in criminal cases he tends to act for those who engage him at the investigative stage.
