Julian Davis Mortenson teaches constitutional and transnational law. His research focuses on the allocation of public authority in both international and domestic law, frequently from a historical perspective. His scholarship has appeared in the American Journal of International Law, the Chicago Law Review, the Harvard International Law Journal, and the Michigan Law Review, among other publications, and he has written for Opinio Juris, the Kluwer Arbitration Blog, and Slate. He currently serves as co-editor of the "Contemporary Practice of the United States" section of the American Journal of International Law.
Prof. Mortenson is active in both international arbitration and domestic constitutional litigation. He has served as arbitrator, counsel, or expert witness in commercial and investor-state disputes under the ICC, ICSID, UNCITRAL, and VIAC rules, and has litigated complex transnational matters in the U.S. courts, including actions involving the enforcement of foreign law and foreign judgments. He was one of the principal drafters of the merits briefs in the landmark case Boumediene v. Bush, which secured the right of Guantanamo detainees to petition for a writ of habeas corpus. He also represented a group of discharged military service members challenging the "Don't Ask, Don't Tell" law prior to its congressional repeal, and he currently represents seven same-sex couples challenging Michigan's refusal to recognize their marriages under state law.
Before joining the faculty, Prof. Mortenson worked at the law firm WilmerHale, in the President's Office of the International Criminal Tribunal for the former Yugoslavia, and as a law clerk for both Justice David H. Souter and Judge J. Harvie Wilkinson III. Prior to law school, he was a management consultant with a client portfolio spanning the finance, manufacturing, oil and gas, and information technology industries. Prof. Mortenson was salutatorian of his class at Stanford Law School and received an AB in history, summa cum laude, from Harvard College.
