A Nevada commissioner has rejected Rupert Murdochs bid to change his family trust to consolidate control of his media empire in the hands of his son Lachlan, the New York Times reported on Monday, citing a sealed court document.Nevada commissioner Edmund Gorman concluded in a decision filed on Saturday that Rupert Murdoch and his eldest son, Lachlan, who is the head of Fox News parent Fox Corp and News Corp, had acted in bad faith in their effort to amend the irrevocable trust, the Times reported.The court docket indicates it issued a recommendation or order Saturday under seal.The trust currently would divide control of the company equally among Rupert Murdochs four oldest childrenLachlan, James, Elisabeth, and Prudenceafter his death.Potentially, three of the heirs could out-vote a fourth, setting up a battle over the future of the companies, even as Lachlan Murdoch runs Fox and is sole chair of News Corp.A spokesman for Rupert Murdoch, 93, could not immediately be reached for comment.Rupert Murdochs proposed amendment would have blocked any interference by three of Lachlans siblings, who are more politically moderate.In his opinion, Gorman said the plan to change the trust was a carefully crafted charade to permanently cement Lachlan Murdochs executive roles inside the empire regardless of the impacts such control would have over the companies or the beneficiaries of the family trust, the Times said.A lawyer for Rupert Murdoch, Adam Streisand, said they were disappointed with the ruling and intended to appeal, the Times reported.Dawn Chmielewski, Katharine Jackson, and Eric Beech, Reuters
