In Center for Food Safety v. Regan, No. 19-72109 (Dec. 21, 2022), the Ninth Circuit heard a challenge to the Environmental Protection Agency’s (EPA) registration of sulfoxaflor, a widely used insecticide, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
In its briefing to the court, the EPA had conceded two legal errors. First, the agency admitted that it violated the Endangered Species Act’s (ESA) requirement to undertake certain steps to ensure their actions are not “likely to jeopardize” endangered or threatened species or “result in the destruction or adverse modification” of the “critical” habitat of such species. 16 U.S.C. § 1536(a)(2). Second, the agency “recognize[d]” that its regulatory explanation under FIFRA “could be more robust.” Having made these concessions, the EPA sought a remand without vacatur, to allow the agency to fix its professed legal errors.
