Atlantic City - In a stunning development, the New Jersey Casino Control Commission today denied a license renewal for the troubled Tropicana Casino & Resort, saying that a trustee would operate the Boardwalk facility immediately until a buyer was found. It was only the second time a license renewal has been denied in the 29-year history of legalized gambling in Atlantic City. The Tropicana's attorney, Paul O'Gara, said the casino owner, Columbia-Sussex Corp., would appeal the decision, as soon as tomorrow morning, in state court.
