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.

Yaakov Roth's goal is to strategically develop and effectively present the key legal arguments that will secure victory for clients through appellate advocacy and dispositive motions. He has represented clients in high-profile Supreme Court cases, argued appeals in the federal Courts of Appeals, and prepared motions to dismiss and for summary judgment across a range of substantive areas.
Yaakov's most recent Supreme Court experience includes vindicating former Virginia Gov. Bob McDonnell from political corruption charges, narrowing the geographic scope of private civil RICO lawsuits, and pursuing a major challenge to the Affordable Care Act from inception through high court review. At the appellate level, Yaakov's oral advocacy has included pressing a First Amendment challenge to an Ohio law prohibiting "false" campaign statements, seeking disclosure of a Justice Department policy manual concerning criminal discovery, and protecting the religious freedom rights of Death Row inmates. He has successfully defended his clients against defamation, antitrust, Title VII, and ERISA claims — including nationwide class actions — and pursued a host of challenges to federal, state, and local regulations. His ERISA experience also includes a series of withdrawal liability arbitrations and related litigation.
Yaakov speaks and writes about the Supreme Court and First Amendment issues and maintains an active pro bono practice centered around religious freedom and criminal justice.

William K. Townsend Professor of Law, Yale Law School
Nicholas R. Parrillo is Townsend Professor of Law at Yale, with a secondary appointment as Professor of History. His research and teaching focus on administrative law and government bureaucracy and extend to legal history, remedies, and legislation. He has received the ABA’s award for the year’s best scholarship in administrative law and the Law and Society Association’s Hurst Prize for the year’s best book in legal history.
Parrillo’s Yale Law Journal article finding new originalist evidence of broad congressional delegations to agencies was discussed in the Solicitor General’s winning brief in the Supreme Court’s latest nondelegation case and in the en banc 5th Circuit opinion in that case. His Harvard Law Review article on how the judiciary handles the federal government’s disobedience to court orders has been discussed in The Washington Post, The Wall Street Journal, and The New York Times. Parrillo also authored a study that provided the empirical basis for best practices adopted by the Administrative Conference of the United States (ACUS) on the federal government’s ubiquitous but controversial use of guidance documents. Peer scholars at Jotwell, in selecting the “best new scholarship” in law, selected each of these three publications (one of them twice). Parrillo’s most recent article, invited for GW’s annual administrative law issue, reveals and analyzes dramatic variation among industries in their willingness to sue their federal health-and-safety regulators.
Parrillo has testified before Congress, been quoted by the Supreme Court, is a senior fellow of ACUS, and has been an instructor at the New York Historical Society’s graduate institute and an invited speaker before the 2nd Circuit Judicial Conference, the U.S. Department of Justice (in 2019 and again in 2024), the ACLU’s national legal staff, and the Federalist Society’s national convention (two times). He is a recipient of the Law School’s annual teaching award.

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.
