Neil S. Siegel

Neil S. Siegel is Professor of Law and Co-Director of the Center on the Structural Constitution at Texas A&M School of Law. He is also Professor Emeritus of Law at Duke Law School, where he taught for twenty-one years. Professor Siegel’s research and teaching fall primarily in the areas of U.S. constitutional law and federal courts. 

Professor Siegel's scholarship addresses a variety of areas of constitutional law and, in doing so, considers ways in which a methodologically pluralist approach can accommodate changes in society and the needs of American governance while remaining disciplined and bound by the rule of law. His book and articles on collective-action federalism offer constitutional justification for robust, but not limitless, federal power. His contributions in the area of separation of powers document and conditionally justify the role of historical governmental practices and norms in constraining political partisanship and partially constituting congressional, executive, and judicial power. His writings on the politics of constitutional law and judicial statesmanship seek to understand how participants in the practice of constitutional law can vindicate the preconditions for the legitimacy of constitutional law. His constitutional theory scholarship analyzes, among other issues, how perceptions of the clarity or ambiguity of the constitutional text are affected in part by purposive, structural, historical, doctrinal, and consequentialist considerations. His work on gender equality and reproductive rights examines how equality values are protected under both equal protection and substantive due process, and extends the skepticism of constitutional gender equality doctrine to pregnancy discrimination and restrictions on access to contraception, abortion, and gender-affirming medical care.

Professor Siegel served as special counsel to U.S. Senator Christopher Coons during the U.S. Supreme Court confirmation hearings of Ketanji Brown Jackson, Amy Coney Barrett, and Brett Kavanaugh, and he advised Senator Coons during the U.S. Supreme Court confirmation hearing of Neil M. Gorsuch. Professor Siegel also served as special counsel to U.S. Senator Joseph R. Biden during the U.S. Supreme Court confirmation hearings of John G. Roberts and Samuel A. Alito. During the October 2003 term, he clerked for Associate Justice Ruth Bader Ginsburg at the U.S. Supreme Court. He also served as a Bristow Fellow in the Office of the Solicitor General at the U.S. Department of Justice during the tenure of Solicitor General Theodore B. Olson, and as a law clerk to Judge J. Harvie Wilkinson III of the U.S. Court of Appeals for the Fourth Circuit. 

Professor Siegel is a member of the American Law Institute and the Bar of the State of North Carolina.
