The global boutique for sovereign disputes.
We are experienced advocates in international investment arbitration, international commercial arbitration, and arbitration-related litigation proceedings in national courts.
With presences in Washington DC, London, and The Hague, we operate as an integrated worldwide practice.
Our extensive experience in our primary areas of competence spans the globe, and encompasses a track record of successfully representing clients in North America, Europe, Eurasia, and Asia. Our relationship with a market-leading barristers’ set in London allows us to draw upon their experience seamlessly to serve our clients with arbitration and international disputes needs.
Beyond dispute resolution, we support governments on regulatory and policy matters; capacity-building; and the negotiation and implementation of treaties, model investment agreements, and domestic legislation governing investment.
We bring a wealth of experience from the world’s most prominent law firms and international arbitration practices, as well as senior-level government positions. Our unique platform allows us to offer unparalleled value for senior level engagement in all our representations. We invite you to learn more about us.
