Paul served as the 43rd Solicitor General of the United States from June 2005 until June 2008. Before his confirmation as Solicitor General, he served as Acting Solicitor General for nearly a year and as Principal Deputy Solicitor General for over three years.
Paul has argued over 100 cases before the United States Supreme Court, including McConnell v. FEC, Tennessee v. Lane, United States v. Booker, MGM v. Grokster, Hobby Lobby v. Burwell, Epic Systems Corp. v. Lewis, Rucho v. Common Cause, Facebook v. Duguid, and TransUnion v. Ramirez. Paul has argued more Supreme Court cases since 2000 than any lawyer in or out of government. He has also argued many important cases in the lower courts, including Walker v. Cheney, United States v. Moussaoui and NFL v. Brady.
Paul’s practice focuses on appellate matters, constitutional litigation and strategic counseling. He represents a broad array of clients in the Supreme Court and in federal and state appellate courts. Last year, for example, he successfully argued Supreme Court cases involving significant issues of energy regulation, statutory interpretation, state sovereign immunity and Article III standing, and successfully argued a trademark appeal in the Fourth Circuit, and a constitutional appeal before the en banc Eleventh Circuit.
Paul focuses on high-stakes appeals. In recent years, he successfully defended a $1.2 billion jury verdict for clients in a Tenth Circuit case, while securing the reversal of an over $2 billion jury verdict for another client in the Seventh Circuit and the approval of a nearly $1 billion dollar class action settlement in the Third Circuit. He has initiated major administrative law challenges and constitutional litigation against the federal government, such as the successful challenge to the HHS drug-pricing rule and threatened challenges that led to the withdrawal of the Treasury Department’s proposed cryptocurrency regulations. He also counsels clients on a variety of strategic legal questions, whether arising from pending legislation, government inquiries or ongoing litigation.
Paul has undertaken substantial pro bono engagements in the Supreme Court, such as twice successfully representing the defendant in Bond v. United States and successfully representing the Omaha Tribe in Nebraska v. Parker, the guardian ad litem in Adoptive Couple v. Baby Girl, the defendant in Sekhar v. United States, a high school football coach in Kennedy v. Bremerton, and the Little Sisters of the Poor. Paul’s pro bono representation also precipitated the federal government’s confession of error in United States v. Rojas.
Following law school, Paul clerked for Judge Laurence H. Silberman of the U.S. Court of Appeals for the D.C. Circuit and for Associate Justice Antonin Scalia of the U.S. Supreme Court. After his clerkships, he went on to serve as Chief Counsel of the U.S. Senate Subcommittee on the Constitution, Federalism and Property Rights.

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.
