Accusing the state of essentially reneging on a 2010 deal, the Seminole Tribe of Florida is asking a federal judge to declare that tribal casinos have permission to keep operating banked card games, including blackjack, for 15 more years.

In a motion for summary judgment filed Friday, the Seminoles also asked U.S. District Judge Robert Hinkle to order the state back to the negotiating table in a last-ditch effort to try to resolve differences over the games.
