Casino officials from the Sault Ste. Marie Tribe of Chippewa Indians said the legal move blocks the gaming board's intentions to force a sale next month. The bankruptcy filing buys time for Greektown to continue operations and refinance loans needed to finish an expansion, including a 400-room hotel, the Detroit Free Press reported Saturday.

"As we reorganize our business and complete our permanent casino construction with additional financing, the goal is a bigger and more viable Greektown Casino," said Tom Miller, chairman of the casino's management board. "As we work through the reorganization process, the casino will continue to operate normally for all guests, player's club members, employees, vendors, suppliers and contractors."

Gaming board Executive Director Rick Kalm said in a statement there would be no immediate changes at the casino.

"We will continue to regulate the day-to-day operation as it pertains to the Michigan gaming control act and ensure the daily tax returns are prepared and filed with the state of Michigan and subsequently to the city of Detroit," said Kalm.
