DOVER, Del. -- Attorneys for professional sports leagues and the NCAA are asking a court to quickly rule on their appeal of whether Delaware's plan to allow betting on games should be halted. The leagues are worried that if the court doesn't quickly rule, the bets could start early next month. The leagues asked the Third U.S. Circuit Court of Appeals on Monday to expedite the appeal. They are trying to overturn a ruling by a federal judge in Delaware last week denying their request to stop the betting. The judge has set a Dec. 7 trial date on the leagues' claims that the sports betting plan violates a federal ban on sports gambling, as well as Delaware's state constitution. Court documents indicate that attorneys for the state are opposing an expedited appeal.
