The state of Florida has filed a federal lawsuit against the Seminole Tribe, accusing the tribe’s casinos of offering card games in violation of state and federal law.

The state and the tribe struck a deal in 2010 giving the tribe exclusivity over house-banked card games at five of the tribe’s seven casinos – three in Broward county and two more in Immokalee and Tampa – for which the tribe guaranteed the state a minimum payment of $1b.

That gaming compact expired in July and this week saw the end of the 90-day grace period by which the tribe was supposed to cease offering games like blackjack, baccarat, pai gow and the like. Instead, the tribe is defying the state by continuing to offer the games.

The Seminoles are a federally recognized tribe, meaning the state lacks the legal jurisdiction to send in its own cavalry to force the Seminoles into toeing the line. So on Friday, the state’s Department of Business and Professional Regulation formally asked a federal judge to force the tribe to shut down their gaming tables.
