No. 21–429. Argued April 27, 2022—Decided June 29, 2022
Castro-Huerta was convicted of child neglect in Oklahoma state court. The Supreme Court subsequently held that the Creek Nation’s eastern Oklahoma reservation was never properly disestablished and remained “Indian country.” Castro-Huerta then argued that the federal government had exclusive jurisdiction to prosecute him (a non-Indian) for a crime committed against his stepdaughter (Cherokee Indian) in Tulsa (Indian country). The Oklahoma Court of Criminal Appeals vacated his conviction.
The Supreme Court reversed. The federal government and the state have concurrent jurisdiction to prosecute crimes committed by non-Indians against Indians in Indian country. States have jurisdiction to prosecute crimes committed in Indian country unless preempted either under ordinary preemption principles, or when the exercise of state jurisdiction would unlawfully infringe on tribal self-government. Neither preempts state jurisdiction in this case.
