The Seminole Tribe has given the state 30 days to strike a new accord about exclusive rights to operate banked card games and has put the state on notice that tribal casinos don't have to shut down the games even in the absence of a revamped deal.

Wednesday's letter from tribal chief James Billie is the Seminoles' latest effort to force state leaders into negotiations about the lucrative card games and comes a month before a deal giving the tribe “exclusivity” over the games is set to expire.

Billie sent state leaders a “notice of commencement of compact dispute resolution procedures,” setting in motion a 30-day period for both sides to meet over the banked card games, which include blackjack. The dispute resolution mechanism requested by the tribe is included in a 20-year agreement, inked in 2010, that set out the parameters for the Seminoles' gambling operations in Florida.
