Dispute resolution: arbitration

Schellenberg Wittmer Ltd

Accomplished at both a domestic and international level, the ‘strategic, commercial, technically excellent’ practice at Schellenberg Wittmer Ltd has core streams of work including commercial, investment, and sport-related disputes. The practice is helmed by Elliott Geisinger, whose strengths lie in commercial arbitration and investor-state disputes, Christopher Boog, who is well-versed in disputes arising from engineering, commodities and investment issues, and Philippe Bärtsch, who maintains a broad practice that spans M&A, infrastructure and licence disputes. Anya George is entrusted by a consortium of clients, such as states, state-owned entities and private companies, with a range of insurance, commodities and manufacturing mandates, while Stefan Leimgruber holds a wealth of experience in international joint ventures, share purchase agreements and construction contract issues. Philipp Groz is also recommended. Greg Lourie joined the team at the beginning of 2025 with expertise in investment arbitration proceedings.
