Investor-state Arbitration

A leading investor-state arbitration practice

Our global investor-state arbitration team specialises in cross-border, multi-jurisdictional and complex cases under International Investment Agreements. We advise our clients at every stage in the arbitration process – from commencement of proceedings to enforcing arbitral awards or resisting challenges to awards.

We have a strong track record of advising states and state-owned entities, as well as claimant investors. We also have numerous members of our international arbitration team sitting as arbitrators in investor-state disputes. This gives us a unique insight into the operation of the investor-state system, particularly in relation to jurisdictions which have less experience of the regime. We are particularly well known for operating in emerging markets and challenging jurisdictions.

Our breadth and depth of arbitration experience is unparalleled at a global level in the market and we have a vast amount of experience in all major centres and with many of the specialist arbitral institutions, including ICSID and UNCITRAL.

Our experience includes acting on a number of high-profile and often politically sensitive cases that have required careful management to ensure a favourable result for our clients across the globe.
