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 is a recipient of 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 articles include a study in the Yale Law Journal finding new originalist evidence against a narrow constitutional understanding of administrative regulatory power; a study in the Harvard Law Review giving the first general assessment of how the judiciary handles the federal government's disobedience to court orders; and a study that provided the empirical basis for the best practices adopted by the Administrative Conference of the United States (ACUS) on the federal government’s ubiquitous but controversial use of guidance documents and was the focal point for an online symposium on that controversy. Peer scholars at Jotwell, in selecting the “best new scholarship relevant to the law,” selected each of these three studies (one of them twice). Parrillo has testified before Congress, been quoted by the U.S. 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 Second Circuit Judicial Conference, the law-and-science committee of the National Academy of Sciences, the U.S. Department of Justice’s summit on administrative procedure, and two times before the Federalist Society’s national convention. He is a recipient of Yale Law School’s annual teaching award.
