International Arbitration

Drawing on a global team of more than 30 lawyers, Weil represents both private and government clients in high-stakes and cutting-edge international arbitrations. Our team of talented, culturally and geographically diverse practitioners is well known not only for its arbitration expertise, but also for its experience in alternative dispute resolution techniques and political advocacy, which enable us to achieve exceptional, creative solutions for our clients in jurisdictions around the world.

Notable Representations, Key Contacts

The lawyers on our team combine trial experience, deep knowledge of international arbitration law and procedure, experience across a broad range of industries and substantive areas of law, and the ability to work fluently in multiple different languages. We are skilled and creative negotiators who understand and focus relentlessly on our clients’ goals, and often achieve successful early resolution of disputes.

  • We have tried and won arbitrations under all the major arbitral rules, including: ICC; ICSID; LCIA; ICDR; AAA; SCC; HKIAC; SIAC; as well as numerous ad hoc arbitrations under UNCITRAL and other rules.
  • We have experience in a broad range of sectors, including energy, oil and gas, power and renewables, life sciences, media and telecommunications, mining, financial services, hospitality, and renewable resources such as lumber.
  • Our team includes lawyers who have sat as arbitrators.

Principal Areas of Expertise

International Commercial Arbitration: The diversity of our practice in international commercial arbitration and our more than four decades of success help distinguish Weil. We combine substantial knowledge of the law of international arbitration with deep knowledge of the substantive law, industry, and region at issue in each of our cases.

Investor-State Arbitration: We have successfully represented both investors and states in arbitration arising out of bilateral investment treaties (BITs), multilateral investment treaties (such as NAFTA, CAFTA-DR, and the Energy Charter Treaty), investment agreements, and domestic investment laws. We combine a substantive understanding of international investment law with skills in arbitral advocacy, a deep understanding of the political and commercial settings in which these cases arise, and experience in successfully resolving these cases – both by arbitrating them to conclusion and by negotiating settlements. Importantly, we have handled not only investor-state arbitration cases through to award, but also ICSID annulment proceedings and other post-award challenges, as well as recognition and enforcement proceedings.
