Disney is asking a federal appeals court to overturn a $319 million judgment awarded two years ago to the British production company behind Who Wants To Be A Millionaire. Lawyers for Disney’s ABC Network and Buena Vista Television are scheduled to argue their case today before a three-judge panel of the U.S. Court of Appeals in Pasadena, Bloomberg reports. “The district court committed a cascading series of errors that yielded a verdict radically transforming the parties’ carefully negotiated allocation of risks and rewards,” according to a court filing by the Disney units. Celador originally filed suit against Disney in 2004, claiming that Disney and its TV subsidiaries ABC, Buena Vista Television and Valleycrest Prods. involved in shady dealmaking to deny Celador its fair share of profits from its show. A jury in July 2010 agreed that Disney units breached the contract and awarded Celador $269 million in damages. U.S. District Judge Virginia A. Phillips then added $50 million in pre-judgment interest. Phillips later refused Disney’s bid to overturn the verdict, leading to today’s federal appeals court hearing.
