The U.S. Supreme Court on Wednesday widened the power of states over Native American tribes and undercut its own 2020 ruling that had expanded Native American tribal authority in Oklahoma, handing a victory to Republican officials in that state.

In a 5-4 decision authored by conservative Justice Brett Kavanaugh, the court ruled in favor of Oklahoma in its bid to prosecute Victor Castro-Huerta, a non-Native American convicted of child neglect in a crime committed against a Native American child - his 5-year-old stepdaughter - on the Cherokee Nation reservation.

The change of course only two years after the previous ruling in a case called McGirt v. Oklahoma was made possible by conservative Justice Amy Coney Barrett's 2000 appointment by Republican former President Donald Trump to replace the late liberal Justice Ruth Bader Ginsburg. Conservative Justice Neil Gorsuch, as he did in 2020, joined the court's liberal bloc in favor of Native American interests, but its expanded conservative majority meant that this time he was in the minority.

"To be clear, the court today holds that Indian country within a state's territory is part of a state, not separate from a state," Kavanaugh wrote.

Kavanaugh added that "under the Constitution and this court's precedents, the default is that states may exercise criminal jurisdiction within their territory."

In the McGirt decision, the Supreme Court had recognized about half of Oklahoma - much of the eastern part of the state - as Native American reservation land beyond the jurisdiction of state authorities. That ruling, criticized by Governor Kevin Stitt and other Republicans, meant that many crimes on the land in question involving Native Americans would need to be prosecuted in tribal or federal courts.

Wednesday's ruling affects Oklahoma and could be extended to other states. About 20 states where tribal reservations are located could seek new authority to exert criminal jurisdiction over crimes committed by non-Native Americans against native Americans on Native American land.

That includes western states with large Native American populations including Arizona and New Mexico. Until now, states generally lacked jurisdiction over such crimes, which were prosecuted by the federal government.


Writing in dissent, Gorsuch called Wednesday's ruling a "grim result for different tribes in different states," but said its impact could still be limited by individual treaties and laws passed by Congress.

"One can only hope the political branches and future courts will do their duty to honor this nation's promises even as we have failed today to do our own," Gorsuch added.

Chuck Hoskin, principal chief of Cherokee Nation, said in a statement that the justices had ignored court precedent and "basic principles" of law.

"While we are disappointed in this ruling, it does not diminish our commitment to meeting our public safety responsibilities and to protecting Oklahomans on our reservations and across the state," Hoskin added.

Thirty-five states are home to federally recognized tribes, according to the National Congress of American Indians. Before the Supreme Court ruling, 16 had already been given authority by Congress to assert jurisdiction over at least some tribal land for crimes involving Native Americans.

As a result of the McGirt ruling, about 3,600 cases every year in Oklahoma were set to fall under federal instead of state jurisdiction.

Oklahoma Attorney General John O'Connor, a Republican, said in a statement that as a result of the McGirt ruling many crimes were not being prosecuted by the federal government.

"Now the state prosecutors can take up the slack and get back to what we have been doing for 113 years," O'Connor added.

The state already prosecutes crimes committed in the affected land in which no Native Americans are involved. Tribal courts handle crimes committed by and against Native Americans.

Tribes had welcomed the McGirt ruling as a recognition of their sovereignty. The Supreme Court in January rejected Oklahoma's request to outright overturn it.

Castro-Huerta was convicted in state court of neglecting his stepdaughter, who has cerebral palsy and is legally blind, and sentenced to 35 years in prison. The Oklahoma Court of Criminal Appeals last year threw out that conviction because of the 2020 precedent. Castro-Huerta by then was already indicted for the same underlying offense by federal authorities, transferred to federal custody and pleaded guilty to child neglect. He has not yet been sentenced.

There are 574 federally recognized tribes in total although some states have very little tribal land. The population of Native Americans and Alaska Natives combined in the United States is 3.7 million, according to the 2020 U.S. Census.
