Duro v. Reina

Duro (defendant), a member of the Torres-Martinez Band of Cahuilla Mission Indians, was living on Salt River Pima-Maricopa Indian land when he shot and killed a boy there in 1984; federal murder charges against him were dismissed, and the Pima-Maricopa tribe instead charged him with illegally firing a weapon on reservation land. Duro moved to dismiss for lack of tribal jurisdiction since he was not a Pima-Maricopa member; the tribal court denied the motion, a federal district court granted habeas relief on jurisdictional grounds, and the Ninth Circuit reversed, leading to Supreme Court review.
