WICHITA, Kan. (AP) — Kansas has asked a federal court to temporarily block the Quapaw Tribe from expanding its Downstream Casino in Oklahoma into southeast Kansas.

The request for a preliminary injunction filed Thursday contends the state will suffer irreparable harm if the tribe's casino goes forward. It notes the tribe has already moved in construction equipment.

The state says it is considering proposals for a southeast gaming casino and the tribe's competition lowers the value of the state's facility.

Kansas contends the tribe misled the state and Bureau of Indian Affairs. It challenges a National Indian Gaming Commission decision to allow gambling on Cherokee County land now being used as a parking lot.

The tribe pulled out of a partnership with a proposed casino north of Pittsburg after the federal lawsuit was filed.
