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.

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.

A unique court case has begun in Nevada this week. At stake is the future of the Murdoch empire and the decision about his succession plan.

The secret family affair now playing out inside a Reno, Nevada, courtroom like a page ripped from the scripted fireworks of the HBO show “Succession,” won’t be seen on television, or even in the written press.

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.

“The Motion for Access to the hearings in this case is denied,” probate commissioner Edmund J. Gorman Jr. ruled today, just four days before the Murdoch family succession case is set to start in Reno. “All hearings in this case shall remain closed to the public and to the media, including the movants.”
