A coalition of media organizations, including CNN, has petitioned a Nevada court to open up the secret proceedings surrounding a legal battle over the future of billionaire Rupert Murdoch’s media empire.

The New York Times, Associated Press, National Public Radio, The Washington Post, Reuters and CNN filed a motion Wednesday in the Second Judicial District Court in Nevada to make public the proceedings, objecting to the case being so extensively sealed that it doesn’t even appear on any court schedule or docket.

The Murdoch family, famous for helming one of the world’s most influential media empires that includes Fox News, The Wall Street Journal and outlets in Australia and the UK, is locked in a secret court battle over succession and control of the future of the family business, according to a New York Times report published in July citing sealed court documents.
