“Stephen Anway is one of the brightest disputes lawyers of his generation. Fierce intellect and insight that is unmatched in the industry.” – Legal 500 2023
Stephen Anway is a partner, former member of the firm’s Global Board, and global co-chair of the firm’s world-ranked International Dispute Resolution (IDR) Practice Group, which Law360 recently named International Arbitration Group of the Year out of 800 other law firms. In that role, he leads a team of more than 150 lawyers across 25 offices in North America, Europe, the Middle East and Asia Pacific.
For more than 20 years, Stephen has acted as counsel and arbitrator in some 125 international arbitrations – both commercial and investment treaty – under all major arbitral rules and institutions. During that time, he has worked in more than 40 countries and has achieved several of the largest victories in the history of the field.
Law360 recently ranked Stephen as one of the top five MVPs in international arbitration globally. In 2025, Jus Mundi named him to its Power List: Top Male Arbitration Lawyers, recognizing the 50 standout practitioners who shaped international arbitration in 2023-2024. In 2024, Jus Mundi ranked the group that Stephen leads as the No. 1 firm in the world representing sovereign nations in investment treaty arbitrations, and No. 3 in the world representing companies in international commercial arbitrations.
Stephen also is an adjunct professor of law and is currently teaching international arbitration at the No. 1 ranked US law school in the field of dispute resolution, according to the 2025 US News and World Report rankings. Prior to accepting his current teaching position, Stephen taught international arbitration for a decade at a top 10 law school in the field of international law, where he was awarded Judge Richard M. Markus Adjunct Professor of the Year Award, which recognizes an exceptional adjunct professor based on professional achievement, teaching and service.
The IDR group that Stephen leads has represented 32 different sovereign nations, as well as the European Union, and numerous foreign investors in dozens of investor-state arbitrations, many of which involve claims in excess of US$1 billion (and some involving tens of billions of dollars).
In December 2019, the Slovak Republic appointed Stephen to the Panel of Arbitrators of the International Centre for Settlement of Investment Disputes (ICSID), an autonomous international institution – affiliated with the World Bank – which is the world’s principal forum for resolving disputes between foreign investors and sovereign nations. Stephen will serve for a term of six years.
Stephen also specializes in international commercial arbitration. In June 2013, The American Lawyer Arbitration Scorecard published its list of the 20 largest commercial arbitration awards in history, and Stephen represented the winning party in three of them. No other law firm had more than two. He is one of the world’s leading lawyers in liquefied natural gas (LNG) and gas arbitrations, having represented the winning party in the first price review arbitral award in history and having now secured more than US$10 billion for his clients in LNG and gas proceedings.
Stephen is a member of the International Council of Commercial Arbitration (ICCA), the London Court of International Arbitration (LCIA) and the International Bar Association (IBA). He also is the General Editor of UCIA – Universal Citation in International Arbitration, published by the Global Arbitration Review.
Stephen began his career with the firm while in law school as a summer associate in 2000 and 2001. He thereafter accepted a two-year clerkship with the Chief Justice of the Supreme Court of Ohio, the late Thomas J. Moyer, who was the then-longest sitting chief justice in the US. After completing the clerkship, Stephen returned to the firm and has been there ever since.
