Charles Kotuby is an international law counsel who represents multinational corporations in complex international disputes. He has acted in international arbitrations and litigations across a range of sectors and industries, including oil and gas, aviation, mining, and other extractive projects.

His practice is focused on investment arbitration and litigation involving foreign sovereigns and on novel issues of public and private international law. He has appeared as counsel in international matters before the U.S. Supreme Court, the Court of Justice of the European Union, ICSID, and UNCITRAL tribunals. Charles has been counsel to Chevron in its multibillion dollar dispute in Ecuador and is currently representing a number of Canadian mining clients with treaty-based claims against the Republic of Kazakhstan. He also advises clients on treaty rights, investment protections, international border, and maritime issues.

According to Judge Stephen Schwebel, arbitrator and former president of the International Court of Justice, Charles is one of the world's "leading international counsel and advocates" (foreword to Kotuby & Sobota, General Principles of Law and International Due Process [Oxford 2017]). Charles's book on international law has been called "astute" (Judge James Crawford),"brilliant" (Pierre-Marie Dupuy), and a "signal contribution" (Judge Schwebel).

Charles is a Fellow in the Chartered Institute of Arbitrators, an adjunct professor of law at the University of Pittsburgh and American University Washington College of Law, and a member of the United States Government Delegation to UNCITRAL Working Group III on Reforms to Investor-State Dispute Settlement and the U.S. State Department Advisory Committee on Private International Law.
