FLAGSTAFF, Ariz. (AP) — An arbitrator has awarded a Las Vegas developer about $28 million in a contract dispute over the Grand Canyon Skywalk, but the tribe that owns the popular tourist attraction in western Arizona contends that the judgment isn’t enforceable.

David Jin invested $30 million to build the glass bridge on the Hualapai reservation that gives visitors a view of the Colorado River below. He and the Hualapai Tribe have been locked in a contract dispute for more than a year that has led the tribe to sever Jin’s interest in the Skywalk and Jin to pursue legal remedies for alleged constitutional rights violations.
