The court’s syllabus:

The panel reversed the district court’s judgment affirming the federal Bureau of Indian  Affairs’ decision in favor of federal defendants in an action brought by the Cahto Tribe of the Laytonville Rancheria, seeking to set aside the Bureau of Indian Affairs’ decision to direct the Tribe to place the names of certain disenrolled individuals back on its  membership rolls.

The panel held that the Tribe’s governing documents did not provide for an appeal to the Bureau of Indian Affairs of the Tribe’s disenrollment action.
