TikTok must face lawsuit over girl's death, rules US court

A US appeals court has revived a lawsuit against TikTok by the mother of a 10-year-old girl who died after taking part in a viral "blackout challenge" in which users of the social media platform were dared to choke themselves until they passed out.

While a federal law typically shields internet companies from lawsuits over content posted by users, the Philadelphia-based 3rd US Circuit Court of Appeals on Tuesday ruled the law does not bar Nylah Anderson's mother from pursuing claims that TikTok's algorithm recommended the challenge to her daughter.

US Circuit Judge Patty Shwartz, writing for the three-judge panel, said that Section 230 of the Communications Decency Act of 1996 only immunises information provided by third parties and not recommendations TikTok itself made via an algorithm underlying its platform.

She acknowledged the holding was a departure from past court rulings by her court and others holding that Section 230 immunises an online platform from liability for failing to prevent users from transmitting harmful messages to others.

But she said that reasoning no longer held after a US Supreme Court ruling in July on whether state laws designed to restrict the power of social media platforms to curb content they deem objectionable violate their free speech rights.

In those cases, the Supreme Court held a platform's algorithm reflects "editorial judgements" about "compiling the third-party speech it wants in the way it wants". Shwartz said under that logic, content curation using algorithms is speech by the company itself, which is not protected by Section 230.

"TikTok makes choices about the content recommended and promoted to specific users, and by doing so, is engaged in its own first-party speech," she wrote.

"But it cannot claim immunity that Congress did not provide," he wrote.
