In July 2020, the US Supreme Court issued its opinion in McGirt v Oklahoma, a decision which resulted in serious and substantial questions and litigation regarding a state’s ability to prosecute crimes which occurred on Indian land. In June 2022, the US Supreme Court issued its opinion in Oklahoma v. Castro-Huerta, which drastically altered what we understood McGirt to hold. In Castro-Huerta, the Court ruled that States have criminal jurisdiction over all crimes committed by non-Indians within Indian Country, including crimes involving Indian victims. Prior to Castro-Huerta, we understood that Oklahoma’s criminal jurisdiction over non-Indians for crimes within Indian Country was limited to victimless crimes and crimes with only non-Indian victims: this is no longer the case. Also prior to Castro-Huerta, we understood that the Indian status of the victim(s) was critical to the criminal jurisdiction analysis: this also is no longer the case.
Here is a chart that is intended to provide you a snapshot of who has jurisdiction over what crime, taking into consideration both McGirt and Castro-Huerta:
