A northeast Wisconsin Indian tribe has asked a federal judge in Madison to stop a competing tribe from expanding a small casino near Wittenberg. The Stockbridge Munsee filed suit Wednesday against the Ho Chunk’s expansion to a full fledged gaming house and hotel. The Stockbridge says it violates the Ho Chunk’s gaming compact with the state — it violates a federal law that bars gambling on land placed in tribal trusts after 1988 — and it would take millions from the Stockbridge North Star Casino less than 20 miles away near Bowler. Also, the plaintiffs say the state has done nothing to stop the Wittenberg project — even though the state gaming agency says it meets the conditions of its state compact. The Stockbridge Munsee has said it would not pay 923-thousand dollars in gaming revenues to the state this summer, as spelled out in its compact.
