WASHINGTON — Oklahoma's largest Indian tribes are squaring off against state Attorney General Scott Pruitt in a U.S. Supreme Court case that could be a major test of tribal sovereignty.

The Oklahoma tribes and Pruitt are not the original parties in the case, which focuses on the jurisdiction of Indian courts. But they filed written arguments presenting vastly different opinions about whether tribal courts should hear civil complaints against non-tribal members.

Pruitt, whose office filed a brief on behalf of Oklahoma and five other states, contends some Indian court systems aren't qualified to handle legal disputes with non-members. The Choctaws, Chickasaws, Muscogee Creeks, Cherokees and Seminoles disagree.

The Supreme Court is scheduled to hear oral arguments on Monday in the case, which pits the Dollar General Corp versus the Mississippi Band of Choctaws.
