Stefan specialises in extradition and criminal law. He regularly prosecutes and defends in the Crown Court. He is on the CPS General Crime Panel (grade 2) and the Specialist Fraud Panel (grade 2). Recently, he has been instructed in several multi-handed cases involving violence. Throughout 2019, Stefan was instructed as disclosure junior on a five-month multi-defendant missing trader intra-community fraud involving a VAT loss of £34m. Stefan has a particular interest in aviation law, including crimes committed aboard aircraft.

Stefan represents requesting states and requested persons at first instance and on appeal to the High Court. He is on the CPS Extradition Panel (grade 2). Following the Court of Justice of the European Union’s judgment on the definition of a “judicial authority” in EU law, he has appeared in cases at first instance relating to Germany, Belgium and Latvia. He is currently instructed on several ‘prison condition’ (Article 3) cases involving Romania, Latvia and Cyprus. Stefan is experienced at arguing cases involving ‘the passage of time’ as a bar to extradition and the interference of extradition with a requested person’s private and family life (Article 8).

Stefan also advises on complex disclosure projects. He is currently instructed in an on-going public inquiry. He has advised foreign governments about the English criminal process, from what constitutes a legitimate ground for arrest to how English courts pass sentence on a defendant.

Stefan is qualified to represent members of the public directly in accordance with the Bar Council’s Direct Access Scheme.
