McGirt v. Oklahoma and the Return of Indian Territory
Near Tulsa, Oklahoma
On July ninth, twenty twenty, the Supreme Court of the United States issued a decision that surprised nearly everyone, including many of the attorneys who had argued for it. In McGirt versus Oklahoma, the court ruled, five to four, that the Muscogee Creek Nation reservation had never been legally disestablished by Congress. The reservation, which covers roughly three million acres in northeastern Oklahoma and includes most of the Tulsa metropolitan area, had existed as a legal matter all along. Oklahoma had simply proceeded as if it had not.
The ruling had immediate and far-reaching consequences. Criminal prosecutions of tribal members for crimes committed on reservation land, which had previously been handled by state courts, now fell under federal or tribal jurisdiction. Hundreds of state convictions were challenged. Oklahoma's justice system absorbed a structural shock it had not anticipated.
The decision was grounded in a close reading of the treaties the federal government had made with the Muscogee Creek Nation before Oklahoma statehood in nineteen oh seven. Those treaties had promised that the reservation would remain intact unless Congress explicitly dissolved it. Congress had reorganized tribal land allotment under the Dawes Act, had pressed tribes toward assimilation, and had enabled the mass transfer of land to non-Native owners. But it had never passed a law explicitly ending the Muscogee Creek reservation. The court held that the absence of that explicit act mattered.
The opinion was written by Justice Neil Gorsuch, who noted that, for the reservation to have ended, Congress must have said so. 'Because Congress has not said otherwise,' he wrote, 'we hold the government to its word.'
The ruling was later narrowed by the court in Oklahoma versus Castro-Huerta in twenty twenty-two, limiting its application in ways that reduced but did not eliminate its impact. The underlying legal principle, that treaty promises require explicit congressional action to undo, remains standing.
