The Ute Mountain Ute Tribe has signed on to a lawsuit filed earlier this year alleging the state of Colorado is blocking the ability of Tribes to engage in online sports betting, a violation of the terms that govern Tribal gaming in the state.

An amended complaint filed with the U.S. District Court for the District of Colorado adds the Ute Mountain Tribe to the complaint and outlines a similar list of claims made by the Southern Ute Tribe.
