A New York appeals court ruled Thursday that Fox Corporation must face Smartmatic’s mammoth defamation lawsuit over the airing of 2020 election lies on Fox News, dealing a blow to the Rupert Murdoch-controlled media giant.

The complaint, which arose out of Fox News’s promotion of vote-rigging conspiracy theories after the 2020 U.S. presidential election, is on track to proceed to trial.

In its initial 2024 complaint, Smartmatic accused Fox News of making “over 100 false statements and implications” about the company. Judges wrote this week that Smartmatic's claims that Fox News ran “a disinformation campaign in [its] post-election coverage” were enough to warrant a trial.
