Tuan Samahon is a law professor at Villanova University in Pennsylvania, where he lectures and publishes in the areas of structural constitutional law with a particular emphasis on the powers to appoint and remove. Tuan Samahon began teaching in 2004 at the William S. Boyd School of Law at the University of Nevada, Las Vegas. He teaches courses in constitutional law, federal courts, and advanced courses in civil procedure.

In late 2009, Tuan Samahon testified before the U.S. Senate Judiciary Committee’s subcommittee on the Constitution regarding executive branch policy “czars” and whether their use violates the Appointments Clause. Professor Samahon elaborated that analysis in his subsequent article, “The Czar’s Place in Presidential Administration, and What the Excepting Clause Teaches Us about Delegation,” which he presented at a symposium hosted by the University of Chicago Law School.

Prior to law teaching, Tuan Samahon practiced law in Washington, D.C., with Covington & Burling LLP with an emphasis on litigation and federal regulatory practice. He clerked for a federal trial and appellate judge. A member of the D.C. bar, Tuan Samahon completed his J.D. at Georgetown University University Law Center in 2000 after receiving a B.A. at Brigham Young University in 1996.
