The move "seemed to indicate its owner, Caesars Entertainment, has little intention of considering selling it, despite public statements to the contrary," according to The Associated Press.
"After 4 p.m. on Aug. 31, 2014, Showboat will cease all gaming operations and Showboat will no longer be open to the public in any capacity," the company wrote in its petition.
The order addresses post-closure concerns, including taking inventory of alcoholic beverages and slot machines before transferring any to the company's other three casinos in Atlantic City; and allowing customers holding Showboat chips after the shutdown to redeem them at the other casinos: Harrah's, Bally's and Caesars.
