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.
Paul is a Distinguished Lecturer in Law at the Georgetown University Law Center, where he has taught in various capacities since 1998. He also serves as a Senior Fellow of the Law Center’s Supreme Court Institute. He is the Justice Joseph Story Distinguished Practitioner in Residence at the Gray Center at Scalia Law School.
