The lawyer representing voting technology company, Smartmatic, says Rupert and Lachlan Murdoch are key to the $US2.7 billion ($4.05 billion) case they have brought against Fox News and Fox Corporation.
The US cable news network is accused of spreading disinformation in the aftermath of the 2020 presidential election, in support of Donald Trump's false claims the election was stolen.
"Rupert and Lachlan Murdoch, from our perspective, are front and centre to the decision making that was done at Fox Corporation that allowed and encouraged this type of disinformation," Erik Connolly told 7.30.
