Natural Resources Defense Council v. United States Environmental Protection Agency
The Natural Resources Defense Council and the Xerces Society (plaintiffs) sued the United States Environmental Protection Agency (defendant) and intervenor Bayer CropScience, challenging the EPA's registration of the insecticide spirotetramat. Plaintiffs alleged procedural and substantive deficiencies, primarily that the EPA failed to publish notice of applications, invite public comment, and publish registration decisions as required by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The court found the EPA had indeed committed serious procedural errors. Despite arguments from the EPA and Bayer against vacatur, the court decided to vacate the EPA's approvals of spirotetramat registrations and remanded the matter for further proceedings consistent with FIFRA and the Administrative Procedure Act.
