By Jody Godoy: LOS ANGELES, Feb 9 – The California state court started the trial which examines social media platforms’ liability for mental health damage caused by their addictive design elements on Monday. The case could become a turning point for how Big Tech companies are legally treated in lawsuits involving children and young users.
The 20-year-old woman K.G.M. who filed the lawsuit claims that Instagram and YouTube caused her mental health problems during her adolescence. She is suing Meta Platforms which owns Facebook and Instagram and Google which owns YouTube.
The court documents show that K.G.M. claims the platforms were built to make users stay online which led to her developing an addiction when she was still a child. She claims that continuous exposure to the content resulted in her developing depression and suicidal thoughts, and she believes that the companies should have informed users about these dangers.
Why This Case Matters
The jury’s verdict against Meta and Google would create a legal pathway for countless other lawsuits which will be filed throughout the United States. Tech companies have long relied on legal protections that shield them from responsibility for content posted by users. A rejection of that defense in this case could significantly weaken that shield—especially when claims focus on product design rather than user content.
Meta, Google, TikTok, and Snap are currently dealing with multiple lawsuits in California which include many cases filed by parents, school districts, and state authorities.
How the Tech Giants Are Defending Themselves
Meta and Google will argue that K.G.M. suffered from mental health problems due to factors that had nothing to do with social media platforms. The company intends to showcase their safety initiatives for young people while denying responsibility for dangerous user-generated content.
Internet companies can avoid liability for third-party content according to existing U.S. laws. The plaintiffs claim that their issue stems from the apps’ design which promotes compulsive usage rather than what users actually posted online.
Broader Legal Pressure Is Building
Federal courts currently handle over 2,300 lawsuits which have similar claims to this state case. The judge handling those cases needs to decide whether the companies can use their liability protections. The first federal trial could begin as early as June.
Meta CEO Mark Zuckerberg will testify at the California trial which is expected to last until March. K.G.M. has settled with TikTok and Snap who were involved in the case but now they have exited the legal proceedings.
What the Jury Will Decide
The plaintiff’s legal team will prove that the companies were negligent and lacked proper user warnings and their platforms caused significant damage to users. The jury will determine damages for pain and suffering along with possible punitive damages if the plaintiffs win their case.
A Global Backlash Against Social Media
This case is part of a broader global push to regulate social media’s impact on children’s mental health. Australia and Spain have implemented social media access restrictions for users under 16 years old while other countries are considering similar actions.
The New Mexico state attorney general has accused Meta of enabling child sexual exploitation while making profits from such activities which will face legal action because of a separate high-profile trial that started Monday in Santa Fe.
The outcome of the Los Angeles trial will create a major shift in social media companies’ accountability because the worldwide legal investigations of social media companies are becoming more intense.
