In the United States, Mr. Donovan argued international law, arbitration law, and commercial law cases before the U.S. Supreme Court, several of the U.S. Courts of Appeals, and other federal and state courts.

In the course of his Debevoise career, he represented states, multinational corporations, international organizations, and nongovernmental organizations. At the time of his retirement from Debevoise, Mr. Donovan had long served as co-chair of both its International Disputes Resolution Group and its Public International Law Group.

Mr. Donovan has also regularly sat as arbitrator in international cases, including under the auspices of ICSID, the PCA, the ICC, and the ICDR, as president, chair, sole arbitrator, and co-arbitrator.
