DENVER – A lawyer for four women who were temporarily banned from the Ute Indian Tribe’s reservation in Utah asked a federal appeals court on Tuesday to revive a lawsuit challenging their punishment.

In 2018, the tribe banned Angelita Chegup, Tara Amboh, Mary Carol Jenkins and Lynda Kozlowicz from its reservation about 150 miles east of Salt Lake City for five years over allegations they tried to destabilize the tribal government and had filed frivolous lawsuits for nearly 30 years, among other things.

The women’s lawyer, Ryan Dreveskracht, told a three-judge panel for the 10th U.S. Circuit Court of Appeals in Denver that courts have previously found that Native Americans have the right to challenge a banishment. He said the punishment puts 15% of the state off limits to his clients.

“This is the only land they have ever known,” he said.

The tribe’s lawyer, Preston Stieff, argued that federal courts have not found that a temporary banishment is the equivalent of being in custody, the legal standard for them to intervene in tribal discipline under the Indian Civil Rights Act. The 1968 law prevents sovereign tribal governments from infringing on the rights of members and nonmembers.

The Ute Indian Tribe said the women tried to disrupt federal litigation between it and Utah to stop the reservation from being reduced in size. The existing reservation boundaries were eventually upheld, the tribe said.

A federal district judge in Utah threw out the women’s claim, citing a 2017 decision by the 9th U.S. Circuit Court of Appeals in another temporary banishment case. It involved members of the United Auburn Indian Community in California who were banished for 10 years after they publicly accused the tribal council of financial mismanagement and claimed that tribal elections were rigged.

The court ruled that they did not have a right to challenge the banishment in federal court because of tribes’ sovereign immunity to determine the makeup of their communities.
