Stefan Hyman


Since successfully completing pupillage and obtaining tenancy in Chambers, Stefan has quickly developed a busy extradition and criminal law practice. He is well-liked by solicitors and clients who value his direct approach and easy manner.

In the context of extradition, Stefan represents requesting states and requested persons at first instance and on appeal to the High Court. In 2020, he was seconded to the CPS Extradition Unit where he was responsible for a wide portfolio of part 1 (European) cases. He is therefore well placed to advise on present challenges to extradition, including the fast-moving litigation concerning prison conditions in Europe and the United States (Article 3), the rule of law and judicial independence in central and eastern Europe (Article 6), which courts are ‘competent’ to issue European arrest warrants following the Court of Justice of European Union’s landmark judgments in 2019, and the impact of the UK’s withdrawal from the European Union on present and future extradition arrangements.

Stefan has particular experience of litigating and appearing as an advocate in German, Italian, Polish, Romanian and Spanish cases. He has also appeared in part 2 (non-European) cases at first instance, including requests from Australia, Brazil and the United States. Stefan is well-versed at arguing cases involving delay and the disproportionate effect of extradition on a requested person’s family life (Article 8).

Alongside extradition work, Stefan maintains a busy practice in the Crown Court, where he both prosecutes and defends. 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 advises on complex disclosure matters. From 2017-2019 he was instructed to provide advice on disclosure to a core participant in a public inquiry. He has advised foreign governments about the English criminal process and provided external training on extradition law and practice.  He is a contributor to Crimeline’s Extradition Hub.

Stefan is qualified to represent members of the public directly in accordance with the Bar Council’s Direct Access Scheme. He is on the CPS General Crime, Extradition and Specialist Fraud Panels at level 2.

Background and expertise

Prior to joining Chambers, Stefan worked for a law firm specialising in public law. In 2015, he was involved in litigation against the Iraq Inquiry in relation to the unreasonable delay in publication of the Inquiry’s report. Following periods living and working in South America, Stefan is fluent in written and oral Spanish.
