Facebook founder Mark Zuckerberg has been ordered to testify in a landmark trial in the US over the impact of social media on young people.
Los Angeles County Superior Court Judge Carolyn Kuhl this week rejected the argument his company, Meta Platforms, had made that an in-person appearance was not necessary.
Her order also applies to Snap boss Evan Spiegel, as well as Adam Mosseri, who leads Meta-owned Instagram.
The trial, expected in January, is among the first to advance from a wave of litigation accusing social media companies of making their apps addictive and enticing to young people despite being aware of mental health and other risks.
Meta did not respond to a request for comment.
