A group of news organizations filed an emergency petition Thursday, asking Nevada’s highest court to unseal the ongoing family succession battle playing out in a Reno courtroom that will determine the future of Rupert Murdoch’s vast media empire.

News Corp. patriarch Rupert Murdoch, 93, wants to ensure eldest son Lachlan gets control of family trust, which has major stakes in Fox News parent Fox and the Wall Street Journal.

Next week, a probate official will hear evidence in a clash between Rupert Murdoch and some of his children over who should control his media companies after he dies.

At most offices, water cooler talk revolves around annoying company rules or the quality of the snacks in the break room. But at Fox News, they gossip about the Murdochs, the family who controls Fox’s parent company.

The conservative slant of Murdoch’s media empire—which includes Fox News and the Wall Street Journal—could be under threat amid a high-stakes succession battle.

The Murdoch family is headed to probate court in Nevada on Monday as Rupert Murdoch looks to amend his trust, which holds major stakes in Fox Corp. and News Corp, according to the Wall Street Journal.

When Rupert Murdoch, the 93-year-old media mogul, quietly decided last year to upend the irrevocable family trust that governs who will control his sprawling global media empire after his death, the move ignited an intense feud among his children.
