CARSON CITY, Nev. (AP) — A hearing Wednesday before Nevada's high court could provide the first public window into a secretive legal dispute over who will control Rupert Murdoch's powerful media empire after he dies. The case has been unfolding behind closed doors in state court in Reno, with most documents under seal. But reporting by The New York Times, which said it obtained some of the documents, revealed Murdoch's efforts to keep just one of his sons, Lachlan, in charge and ensure that Fox News maintains its conservative editorial slant.
