Nicholas R. Parrillo
William K. Townsend Professor of Law, Yale Law School
Biography
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 TheWashingtonPost, The Wall Street Journal, and The New YorkTimes. 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 thesethreepublications (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 (twotimes). He is a recipient of the Law School’s annual teaching award.
