The three regulations addressed: how species are listed and delisted and critical habitat designated under ESA section 4; interagency consultation under ESA section 7; and a final rule repealing USFWS's blanket ESA section 4(d) rule which, prior to its repeal, extended the take prohibitions of ESA section 9 to most species listed as threatened under the statute (collectively, the 2019 Rules). In July 2022, the District Court remanded and vacated the 2019 Rules without making a determination on the merits as to whether the rules were, in fact, unlawful. The Services had requested the District Court remand the 2019 Rules to the agencies without vacatur. The U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit) later stayed the vacatur, requiring the District Court to reconsider. In a separate filing with the District Court subsequent to the decision of the Ninth Circuit and in support of the agencies' original request for remand without vacatur, the Services informed the court that potential revisions to the 2019 Rules could be completed by the agencies on or before May 2023, with any final revisions to be completed by May 2024. The 2019 Rules will remain in effect pending the Services' reconsideration of the same. The content of this article is intended to provide a general guide to the subject matter.
