Career

Stephen is a partner based in our London office. Stephen focuses on competition, regulation and trade practice. Stephen has over 20 years' experience and has been involved in a significant number of landmark competition and regulatory cases at EU and UK level. He focuses on all aspects of EU and UK competition law, including merger control, cartels and abuse of dominance cases, market investigations, competition disputes and strategic advice. Stephen advises clients across a broad range of sectors including financial services, media (particularly broadcasting), telecoms, energy, pharmaceuticals and professional services. As a competition litigator, Stephen has conducted complex competition disputes (both regulatory appeals and private enforcement). He has conducted cases before national competition authorities, in the European courts and the High Court of England and Wales, as well being involved in numerous cases in the UK Competition Appeal Tribunal (CAT) since its inception. Stephen is a qualified solicitor advocate and has appeared as counsel in the CAT and the European Court of Justice. He is also a member of the CAT Users Group. Stephen also advises clients on the application of economic regulation and on contentious regulatory matters particularly in relation to telecoms and all forms of media. His cases are often complex and invariably involve highly technical technical evidence. Stephen speaks and publishes extensively on competition law issues, particularly in relation to competition litigation issues, and was closely involved in the consultation on the revised CAT Rules published in September 2015.
