Our investment treaty arbitration practice undertakes high value and complex disputes between investors and States, as well as related litigation before the English courts, such as enforcement actions and challenges. Our team has deep experience and understanding of the conduct of investment treaty arbitration proceedings including under the ICSID, UNCITRAL, PCA and SCC Rules.

We have represented and advised both investors and States in disputes around the world. Acting for both sides gives us a rounded perspective that is strategically beneficial to our clients. Our lawyers also draw upon their experience sitting as arbitrators and the team is adept at working across jurisdictions with local counsel, experts and third party funders, managing the process as required.

In addition, Stewarts’ expertise covers dispute prevention advice, including advisory work for companies and individuals on the restructuring of their investments to obtain the protections of bilateral or multilateral investment treaties.

Stewarts is the UK’s largest disputes-only firm and is known for its conflict-free status. This means we are able to act freely for and against any States and investors and gives our clients the confidence that we can continue to act throughout a matter up to its conclusion, including at any enforcement stage where we may need to become adverse to third parties (including the major financial institutions).

Our reputation as specialists in the field is confirmed through our ranking in leading directories, Chambers & Partners, Legal 500 and Who’s Who Legal, with members of our team included in Legal 500’s “powerlist” of the leading arbitration lawyers in London. Those directories highlight our team’s excellence and unwavering commitment to our clients.

Our expertise in advising investors and States is complemented by the firm’s reputation as a market leader in entering into innovative fee arrangements (including third party funding) in order to manage risk or suit the economics of our clients’ businesses. We also have built a reputation for running our matters effectively.
