The Comanche Nation said the Department of the Interior and the Bureau of Indian Affairs allowed the Chickasaw Nation and other tribes to elude some of the requirements to place off-reservation land into trust for new casinos.
The lawsuit was filed Thursday in U.S. Western District Court of Oklahoma.
"The Comanche feel like they've played by the rules and their competition didn't,” said RichardGrellner, an attorney for the Comanche Nation.
According to a report shared by the local media, the lawsuit claimed: "BIA officials moved the goal line so close to the Chickasaws and other privileged tribes in Oklahoma that they have needed only to fall into the end zone and open up shop, secure in the knowledge that the score was virtually certain to hold up without any replay."
