Seth Barrett Tillman joins Landmark’s Board of Advisors

Mar 3, 2026 | Blog

Landmark Legal Foundation is proud to welcome Professor Seth Barrett Tillman of Maynooth University School of Law and Criminology to our board of advisors. Landmark has already benefitted from his expertise on several cases, most notably our fight against Jack Smith’s prosecution of Donald Trump.

Professor Tillman is the author of dozens of law review articles, including publications in the University of Pennsylvania Journal of Constitutional Law and the Harvard Journal of Law and Public Policy. His important and insightful commentary has appeared in various publications including The Claremont Review of Books and The New York Times.

Professor Tillman received his undergraduate degree from the University of Chicago. He attended Harvard Law School. After law school he clerked for Judge Jane R. Roth on the U.S. Court of Appeals for the Third Circuit, Judge Mark E. Fuller on the U.S. District Court for the Middle District of Alabama, Judge William J. Martini on the U.S. District Court for the District of New Jersey, and then-Magistrate Judge Malachy E. Mannion on the U.S. District Court for the Middle District of Pennsylvania.

In 2024, Tillman received the John Locke Liberty Award for his extensive, decades-long work to advance separation of powers and principles of originalism in defense of liberty.
