Oklahoma v. Castro-Huerta

Background

A man living in Tulsa, Oklahoma, was convicted in state court for severe child neglect involving his Cherokee stepdaughter. He was sentenced to 35 years in state prison. After this Court’s earlier decision in McGirt, parts of eastern Oklahoma including Tulsa were recognized as Indian country and about two million people there were affected. The man argued the federal government, not the State, had exclusive power to prosecute non‑Indians who commit crimes against Indians there; the Oklahoma Court of Criminal Appeals agreed and set aside his conviction. A federal indictment later led to a 7‑year plea deal, reducing his effective prison time.

Reasoning

The Supreme Court examined whether federal law or tribal self‑government prevents a State from prosecuting non‑Indians who harm Indians in Indian country. The majority concluded that the General Crimes Act does not make federal jurisdiction exclusive and that Public Law 280 does not strip states of preexisting authority in this context. The Court also applied the Bracker balancing approach and found state prosecutions would not unlawfully infringe tribal self‑government here. The Court reversed the state appellate decision and held federal and state governments have concurrent jurisdiction for non‑Indian-on‑Indian crimes in Indian country.

Real world impact

The decision means state and federal prosecutors can both bring charges when a non‑Indian harms an Indian in Indian country. That affects prosecutions across eastern Oklahoma, including Tulsa, and could change where thousands of cases are handled. The ruling is not necessarily permanent for every situation; Congress or future court decisions could still change these rules.
