Tropicana Entertainment LLC will be allowed to place Casino Aztar on the auction block again. A Delaware judge gave Tropicana Entertainment permission today to hold a new sale of Casino Aztar. In March, Tropicana had agreed to sell the casino to Eldorado Resorts LLC for as much as USD 245 million. The transaction was to take place once Eldorado, based in a Reno, Nev., obtained a license to run a casino in Indiana.
