The tribe had failed in a bid for declaratory and injunctive relief to block the launch of of sports betting in Arizona after the Maricopa County Superior Court denied their lawsuit.
With the lawsuit, the tribe hoped to void an amended gaming compact negotiated by Arizona Governor Doug Ducey and 20 federally recognized Indian tribes, which had been approved by the US Department of Interior in May.
The compact, which allows the tribes to expand their casinos and offer new table games, was fought for by both the Tonto Apache and Quechan tribes who sought to block the lawsuit.
