Javier was previously Vice Chairman and Global General Counsel of the PricewaterhouseCoopers network of firms spanning 157 countries. Before that, he led Mayer Brown’s Chicago litigation practice and the firm’s International Arbitration practice globally.

Javier regularly handles high-profile international commercial and investment arbitrations, representing clients from North America, Latin America, Europe and Asia in complex disputes before such institutions as the International Centre for the Settlement of Investment Disputes, the ICC International Court of Arbitration, the Stockholm Chamber of Commerce and the Court of Arbitration for Sport, as well as ad hoc arbitrations under the UNCITRAL Rules. Representative matters include a Mexican investor group in an investor state arbitration against Spain arising from Europe’s first-ever resolution of financial institution, representation of the Government of Argentina in multiple ICSID arbitrations arising from Argentina’s 2001 fiscal crisis, representation of a U.S. agricultural producer in an ICSID arbitration against the Government of Mexico arising from measures to restrict sale of certain sweeteners.

As Global General Counsel of PwC, Javier has been involved in a wide variety of commercial, regulatory and other disputes all over the world, enhancing his ability to bring a client-focused perspective aimed at solving clients’ problems. He also has had an active litigation practice throughout his career, handling trials and appeals in state and federal courts across the United States, including the U.S. Supreme Court.

Javier was named one of the “World’s Leading Experts in Commercial Arbitration” by Euromoney Magazine in 2006. He is a fellow in Chartered Institute of Arbitrators, and has been rated by Chambers and Partners for his “marvelous ability to translate the client’s position into the language of international arbitration,” “a very sophisticated cross-examiner” equally “effective with the written word,” and that “being fluent in Spanish accentuates the decidedly international edge to Rubinstein’s practice, whereby he has acted for U.S., Latin American, European and Asian clients.” Javier has also been named a 2018 ADR Champion by the National Law Journal. Most recently, Javier was recognized as a leading practitioner in The Legal 500, Latin America, for International Arbitration, the 2019 edition of The Best Lawyers in America for International Arbitration – Commercial, and the 2019 edition of Leaders League’s rankings for Litigation & Arbitration – Investment Arbitration and Litigation & Arbitration – International Arbitration.

Since 1996, Javier has served as a Lecturer in Law at the University of Chicago Law School, teaching seminars on U.S. Supreme Court litigation, international commercial arbitration and managing legal risk in a global economy.
