In Defense of Animals, et al. v. US Dept. of the Interior, et al.

This interlocutory appeal arose from an action instituted in the district court to stop the government from rounding up, destroying, and auctioning off wild horses and burros in the Twin Peaks Herd Management Area on the California-Nevada border. Plaintiffs alleged that the government's actions would violate the Wild Free-Roaming Horses and Burros Act (Wild Horses Act), 16 U.S.C. 1331 et seq., and the National Environmental Policy Act (NEPA), 42 U.S.C. 4321 et seq. The court held that the injunction was moot because the roundup sought to be enjoined had taken place. The court noted that, in the event plaintiffs prevailed on the merits of their claims, the district court should consider what relief was appropriate.
