Here is the opinion in Timbisha Shoshone Tribe v. Dept. of Interior.
The court’s syllabus:
The panel dismissed, as moot, an appeal from the district court’s dismissal of a case challenging the Department of the Interior’s recognition of the election results for leadership authority over the Timbisha Shoshone Tribe. The panel held that the Tribe’s recent adoption of a new constitution, which overhauled tribal membership requirements, mooted the appeal because there was no chance that a remand to the Bureau of Indian Affairs would make any difference whatsoever in the election results.
