Professor Sanne H. Knudsen received a B.S. in Environmental Engineering from Northwestern University, an M.S. in Environmental Engineering from the University of Michigan, and a J.D. from the University of Michigan, where she graduated Order of the Coif and was a member of the Michigan Law Review. She is a former law clerk for the Honorable Ronald M. Gould on the U.S. Court of Appeals for the Ninth Circuit.

After practicing law at private law firms in Chicago and Minneapolis, Professor Knudsen joined the University of Âé¶¹ÉçÇø of Law in 2011. She teaches Natural Resources Law, Environmental Law, Administrative Law, and Civil Procedure. In 2018 she became a member of the American College of Environmental Lawyers, where she has served on the Board of Regents.

Professor Knudsen’s scholarship focuses on how existing statutes and tort liability frameworks can be used to reduce or redress long-term and multiple-stressor environmental harms. Her work has been selected through peer-review for republication. Professor Knudsen also writes in the area of administrative law, where her work on the history of Seminole Rock deference was cited by the United States Supreme Court inÌýKisor v. Wilkie.

Professor Knudsen is currently developing a series of articles examining the relationship between administrative law and environmental law. InÌýThe Exoskeleton of Environmental Law,Ìýshe argues that environmental law embodies a unique set of prescriptive choices centered on a commitment to self-restraint for the purposes of self-preservation. In a companion article currently in progress, she will examine how administrative law, though operating as a purportedly value-neutral procedural framework, has been operationalized to undermine the success of environmental law. In a shorter essay entitled Reclaiming Control, Knudsen suggests that Congress would be wise to recalibrate the balance of power between administrative and environmental law through an APA-type legislation specific to the challenges of environmental law.

    In a recent article, Sanne Knudsen of University of Âé¶¹ÉçÇø of Law explores how the overlapping of administrative and environmental law can lead to judicial outcomes that “disregard” public-interest values. In addition to analyzing Supreme Court decisions, Knudsen argues that judicial-review doctrines should have built-in mechanisms to prevent the destabilization of environmental statutes.

    Legal experts view Loper Bright as a major transfer of power from agencies to judges. “You have incredibly technical areas of law for which the U.S. Supreme Court in Loper Bright has now paved a path for individual judges, or panels of three judges, to make decisions without having the technical expertise,” said Sanne Knudsen, a professor at the University of Âé¶¹ÉçÇø of Law, whose scholarship on deference doctrines has been cited by the Supreme Court.

    Because the mandatory 60-day window for advance notice of an upcoming lawsuit expired last week, Quiet Communities is now free to bring litigation at any time. In an email, Sanne Knudsen, a University of Washington law professor representing the group, said that EPA never replied to its March letter. Without specifying a date, Knudsen indicated that a suit is in the works over the agency’s “total failure to carry out the commands of the Noise Control Act for forty years.”
