On May 17, 2023, the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit) issued its decision in Center for Biological Diversity v. U.S. Fish and Wildlife Service (Case No. 20-15654), a case in which a mining company challenged the U.S. Fish and Wildlife Service’s (Service) designation of certain areas in southern Arizona as critical habitat for the jaguar (Panthera onca) under the Endangered Species Act (ESA).

The majority of the land comprising these units is owned and/or managed by federal, state, or tribal governments.

The fisher is a small, carnivorous mammal native to North American ...

Reversing the district court, a divided panel of the Ninth Circuit held that that the Bureau of Reclamation and a local water agency have discretion to release water from Twitchell Dam on the Santa Maria River on the Central Coast of California to comply with the federal Endangered Species Act. San Luis Obispo Coastkeeper v. Santa Maria Valley Water Conservation Dist. (Ninth Cir. No. 21-55479, Sept. 23, 2022).

For the magnificent ramshorn (Planorbella magnifica), a fresh-water snail species native to southeastern North Carolina, efforts to secure protection under the federal Endangered Species Act have progressed at a snail’s pace. Today, twelve years after environmentalists originally petitioned the U.S. Fish and Wildlife Service (Service) to list the species, the Service proposed to list the magnificent ramshorn as endangered, and to designate two ponds spanning 739 acres as critical habitat for the species. The proposed rule was prompted by a lawsuit filed by the Center of ...

This week, the New York Court of Appeals rejected a bid for writ of habeas corpus from an unusual petitioner: Happy, a 51-year-old, female Asian elephant, currently living in captivity at the Bronx Zoo.

In its 5-2 opinion, the court held that habeas corpus only protects against the unlawful and indefinite imprisonment of human beings, and that Petitioner, the Nonhuman Rights Project, could not use the legal mechanism to bust Happy out of the zoo and into an elephant sanctuary.

Though the outcome of the case was not particularly surprising, it did feature some surprising elements—the ...
