‘One of the top arbitration practices in London’, Debevoise & Plimpton LLP is consistently mandated to act in big-ticket investor-state matters. It is also highly experienced in large-scale private fund, insurance and healthcare-related commercial arbitrations. Regularly sought out to act in complex commercial and investment disputes, former UK Attorney General Lord Peter Goldsmith KC is chair of the firm’s European and Asian litigation practice. Jeffrey Sullivan KC, a July 2023 recruit from Gibson, Dunn & Crutcher, is co-chair of international arbitration in Europe and ‘superb lawyer’ Patrick Taylor co-leads the firm’s Africa practice group. The practice further showcases construction-related commercial arbitration specialist Tony Dymond, who works across the firm’s London and Hong Kong offices and Conway Blake, who acts in international commercial and investor-state arbitrations. Samantha Rowe focuses on commercial arbitration, investor-state arbitration and public international law. The next line of experienced practitioners includes construction and engineering expert Robert Hoose, international arbitration and public international law specialist Aimee-Jane Lee, and Gavin Chesney and Shreya Aren, who are ’responsive and well prepared’. Other key figures are Laith Najjar, Monika Hlavkova, Sonja Sreckovic, and Mark McCloskey. Maxim Osadchiy left the firm in May 2024.
