One casino operator is a driving voice in a lawsuit looking to change a tribal sovereignty law. Maverick Gaming, which owns three casinos in Colorado, is a part of a case heading to the US Supreme Court.

The company challenges a 2020 law that allows sports betting on tribal lands only in Washington. The lawsuit claims the existing law established a “discriminatory tribal gaming monopoly.”

In addition to the 2020 law creating a monopoly, Maverick Gaming, LLC v. United States, et al. claims the current rules discriminate unconstitutionally against those who run non-tribal casinos.

Maverick Gaming owns and operates three casinos in Colorado.
