Prof. Tuan Samahon

Professor of Law, Villanova University School of Law
Tuan Samahon

Tuan Samahon teaches and writes in the areas of federal courts and constitutional law. His articles on federal separation-of-powers doctrine, which focus especially on the powers to appoint and remove, have been published in the Stanford Law Review, Ohio State Law Journal, Hastings Law Journal, William & Mary Bill of Rights Journal, the University of Chicago Legal Forum, the Nevada Law Journal, the Northwestern University Law Review's Colloquy (forthcoming), and the University of Pennsylvania Journal of Constitutional Law's Heightened Scrutiny (forthcoming), among others.

Beyond his scholarship, Tuan is engaged in interpreting and fashioning federal constitutional law. He has testified before the U.S. Senate Judiciary Committee, subcommittee on the Constitution, on Appointments Clause issues in the context of executive branch policy czars. Late last year, as pro bono counsel in the U.S. Court of Appeals for the D.C. Circuit, he argued Kuretski v. Commissioner, a U.S. Tax Court case that (collaterally) challenges the constitutionality of the President's statutory authority to remove officers exercising the judicial power of the United States. Tuan and his students also filed an amicus curiae brief in the United States Supreme Court in NLRB v. Noel Canning, a challenge to the President's January 2012 "recess appointments" during a time when the Senate was in pro forma session. 

In addition to representing others, Tuan is also a plaintiff in two federal Freedom of Information Act (FOIA) cases, in which he seeks wrongly withheld executive branch documents important to properly understanding American legal history.

Tuan received his B.A. from Brigham Young University and his J.D. from Georgetown University Law Center, where he was an Olin Law and Economics Research Fellow and was co-awarded the Olin Prize in Law and Economics. Prior to entering teaching, he clerked for U.S. District Judge Raymond Jackson on the Eastern District of Virginia and for U.S. Circuit Judge Jay Bybee on the Ninth Circuit. He also practiced in the Washington, D.C. office of Covington & Burling. In 2007, he was named Professor of the Year by his students at the University of Nevada, Las Vegas. At Villanova, Tuan teaches Advanced Separation of Powers, Civil Procedure, Comparative Immigration Law, Constitutional Law I and II, and Federal Courts.
