From defending state regulatory powers to securing investor protections, we bring a client-focused approach and strategic clarity to every case. For states, we advise on defending complex claims and on designing or refining investment protection regimes to advance national investment strategies. For investors, we guide the structuring and restructuring of investments to maximize treaty protection and minimize exposure to host state interference, both before and after disputes arise.
We represent clients before all major arbitral institutions, including ICSID, the Permanent Court of Arbitration, and under the UNCITRAL rules, as well as in disputes arising under bilateral investment treaties and multilateral agreements such as the Energy Charter Treaty and NAFTA.
With deep experience, institutional knowledge, and a balanced perspective from both sides of the table, we deliver clear strategy, rigorous advocacy, and proven results.
Sector reach: Our investor-state team handles diverse complex claims across industries, including oil and gas, construction, transportation, mining, electricity, telecommunications, banking, energy (including renewables), and nuclear power.
Practice breadth: We act in disputes arising from industry regulation, the balance between a state’s right to regulate and an investor’s right to a stable legal framework, as well as issues involving privatization, nationalization, licensing (exploration, exploitation, and export), and claims of indirect expropriation stemming from legislative changes or alleged contractual breaches between states and investors. Our lawyers are also deeply experienced in matters involving fair and equitable treatment, full protection and security standards, and questions of lawful expropriation. We regularly handle complex procedural and jurisdictional issues, including challenges to jurisdiction and bifurcation applications; disqualification of arbitrators; applications for provisional and interim measures (including Section 1782 discovery); annulment and set-aside proceedings; and enforcement actions, including those involving assertions of sovereign immunity.
Knowledge transfer: Members of our team are deeply engaged in the global arbitration community. They lecture on public international law and arbitration at leading universities worldwide and regularly organize, host, and speak on panels exploring emerging developments in investment law, helping to advance dialogue, thought leadership, and innovation across the field. Our lawyers also contribute to key industry publications, including chapters in Global Arbitration Review’s Guide to Challenging and Enforcing Arbitration Awards and Lexology In-Depth’s Investment Treaty Arbitration.
Global recognition: Ranked by The Legal 500, Chambers, Latinvex, Law360, and Lexology, our lawyers are recognized for results, achieving major victories for both states and investors in high-stakes investment disputes worldwide. Successes include earning a place in The American Lawyer’s Arbitration Scorecard “Top 10 Biggest Defense Wins” for defeating multibillion-dollar claims against the Republic of Kazakhstan and, on the investor side, significant wins against states and state-owned entities.
An offering beyond dispute resolution: We guide our clients, both states and investors, through disputes with a view to their broader strategy and objectives, helping them manage risk, shape investment frameworks, and protect value over the long term.
