WICHITA, Kan. -

A federal judge has ordered an Oklahoma tribe to show cause why the court shouldn't dismiss the last remaining claim in their lawsuit seeking to build a casino on suburban Wichita land.

U.S. District Judge Julie Robinson on Wednesday gave the Wyandotte Nation until July 19 to make its pleading.

The Interior Department has notified the court that it rejected the tribe's application to take the land into trust so the tribe can build a casino there.

Robinson refused last year to order the agency to accept the Park City land into trust, leaving the decision to the Interior Department.

But she retained jurisdiction to ensure the agency processed the tribe's application in a timely manner.

The government wants the court to dismiss the lawsuit's remaining claim of unreasonable delay.
