Practice Group

Our International Arbitration Group, which is one of the largest in Switzerland, comprises leading arbitration practitioners with extensive experience in a wide range of industries and complex arbitration matters not only in Switzerland and under Swiss law, but globally and under different laws. Our team is multicultural and multilingual, with diverse legal backgrounds. This enables us to understand our clients’ diverse perspectives and needs, and to handle matters governed by a wide array of laws, in various languages. We meet our clients’ expectations in terms of legal advice and strategy, and business and industry focus.



We act as lead counsel in disputes of all types and magnitude, including large, complex, multi-jurisdictional commercial, investment and sports disputes, seated in common law and civil law jurisdictions around the world. We act for states, state entities, multinational corporations, small and medium-size businesses and individual commercial players. Our team also has unrivalled experience in setting-aside proceedings before the Swiss Supreme Court.

Our representations range from pre-litigious advice over negotiation strategies to mediation, conciliation, adjudication, dispute boards, arbitration, arbitration-related litigation and (pre-trial) discovery to enforcement proceedings and strategies in Switzerland and elsewhere.

Although we focus on counsel work, we also sit as arbitrator, which allows us to offer our clients insight into how an arbitral tribunal ‘works’.

We remain at the forefront of trends and developments in international arbitration through involvement in international organisations and associations, academia and arbitral institutions.

Our team specialises in the construction, energy, life sciences, mining, shipping, trade, transportation, commodities, sport and entertainment sectors.

  • Infrastructure, construction and engineering
