Samuel H. McCoy II Professor of Law, University of Virginia School of Law
John F. Duffy is the Samuel H. McCoy II Professor of Law and Class of 1966 Research Professor of Law at the University of Virginia School of Law, where he teaches administrative law, torts and intellectual property. Professor Duffy has published articles on a wide range of administrative law and regulatory issues in journals such as University of Chicago Law Review, Yale Law Journal, Stanford Law Review, Virginia Law Review, Columbia Law Review, Texas Law Review, Northwestern University Law Review, NYU Law Review, University of Pennsylvania Law Review and the Supreme Court Review. His 1998 article Administrative Common Law in Judicial Review, 77 Tex. L. Rev. 113 (1998), was one of the first articles to criticize the Chevron doctrine as being irreconcilable with § 706 of the APA; it won the American Bar Association’s Scholarship Award in Administrative Law. His 2008 article “Are Administrative Patent Judges Unconstitutional?” was covered on National Public Radio), in the New York Times (Adam Liptak, In One Flaw, Questions on Validity of 46 Judges, May 6, 2008), and in the Wall Street Journal (Dan Slater, Patently Unconstitutional, May 6, 2008). The NYT and WSJ agreed that he was “a different kind of law professor,” “one of the lucky few” whose “writings actually wind up changing the law.”
As an attorney in the courts, Duffy has twice successfully convinced the Supreme Court to overturn lower court doctrines that had been applied in many cases over decades but that were unanimously held to be irreconcilable with Supreme Court precedents. See TC Heartland v. Kraft Foods Group Brands, 581 U.S. 258 (2017); KSR v. Teleflex, 550 U.S. 398 (2007).
Prior to entering legal academics, Duffy clerked on the D.C. Circuit for Stephen Williams and on the Supreme Court for Antonin Scalia. While clerking, he became known as Justice Scalia’s “hapless law clerk,” who had been tasked with unearthing three-quarters of a century of legislative history that made “no difference” to the outcome in an otherwise forgettable case. See Conroy v. Aniskoff, 507 U.S. 511, 527-28 (1993) (Scalia, J., concurring in the judgment).
In earlier days, Duffy enjoyed being a professional blackjack player unwelcome in all Atlantic City casinos and a semi-professional road runner (best marathon time 2:24:33). He holds an A.B. in physics from Harvard and a J.D. from the University of Chicago.
