After graduating from law school, Mr. Mitchell clerked for Judge J. Michael Luttig of the U.S. Court of Appeals for the Fourth Circuit and for Justice Antonin Scalia of the Supreme Court of the United States. He then served as an Attorney-Adviser in the Office of Legal Counsel of the United States Department of Justice from 2003 through 2006. After leaving the Department of Justice, Mr. Mitchell served as a Visiting Researcher at Georgetown University Law Center, a Visiting Assistant Professor at the University of Chicago Law School from 2006 through 2008, and an Assistant Professor of Law at George Mason University from 2008 through 2010.
In 2010, Mr. Mitchell was appointed Solicitor General of Texas, a position he held until January 2015. After leaving the Texas Solicitor General’s office, Mr. Mitchell served as the Searle Visiting Professor of Law at the University of Texas School of Law before joining the Hoover Institution as a Visiting Fellow from 2015 to 2016. Mr. Mitchell also served as a Visiting Professor of Law at Stanford Law School before opening his own law firm in 2018.
Mr. Mitchell has published numerous works of scholarship in top-10 law journals, and he has written articles on textualism, national-security law, criminal law and procedure, judicial review and judicial federalism, and the legality of stare decisis in constitutional adjudication.

He has also argued before Supreme Court of Texas and in numerous trial courts. Mr. Mitchell has authored the principal merits brief in 11 Supreme Court cases, and has written and submitted more than 20 amicus curiae briefs in the Supreme Court.
Mr. Mitchell devised the novel enforcement mechanism in the Texas Heartbeat Act, also known as Senate Bill 8, which avoids pre-enforcement judicial review by prohibiting government officials from enforcing the statute and empowering private citizens to bring lawsuits against those who violate it. This produced an end-run around Roe v. Wade and allowed Texas and other states to impose pre-viability abortion bans despite the continued existence of Roe.

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.

From 2019 to 2021, she took leave from academia to serve as Deputy Assistant Attorney General in the Department of Justice’s Office of Legal Counsel and later as Associate Deputy Attorney General, where she argued federal cases and assisted with Justice Amy Coney Barrett’s confirmation. Earlier in her career, she clerked for Justice Clarence Thomas and for then-Judge Brett M. Kavanaugh on the D.C. Circuit.
