YouTube has appealed the verdict of a landmark social media addiction lawsuit in Los Angeles, seeking to challenge the jury’s determination that the company designed its platform to hook young users without concern for their well-being.

Lawyers representing YouTube filed a notice of appeal Monday in Los Angeles County Superior Court, less than a week after Meta, which was also a defendant in the case, filed its own notice of appeal. The lawyers are expected to provide their arguments related to the appeal in later court filings.

The case centered on a 20-year-old woman who said she became addicted to social media as a child and that it worsened her mental health struggles. The jury found that negligence by both Google-owned YouTube and Meta was a substantial factor in causing harm to the young woman, identified in court only by her initials, KGM, and her first name, Kaley.

The jury awarded her $3 million in damages and recommended an additional $3 million in punitive damages. Her lead attorney, Mark Lanier, said in a statement last week following Meta’s appeal that Kaley’s legal team is expecting the appellate court to “continue the careful application of the law to this case, affirming the verdict of the trial court.”
