Meta and TikTok have suffered another legal setback after a US appeals court rejected their attempt to stop thousands of lawsuits accusing the social media companies of contributing to problems affecting children and teenagers.
The 9th US Circuit Court of Appeals in San Francisco ruled that Meta and TikTok had attempted to challenge a lower court decision too early. The ruling means the companies cannot use the current stage of the litigation to immediately appeal the rejection of their argument involving Section 230 of the Communications Decency Act.
More than 3,000 federal lawsuits have been brought against social media companies by states, school districts, parents, individuals and other plaintiffs.
The cases broadly allege that platforms including Facebook, Instagram and TikTok were designed in ways that encouraged young users to remain engaged for long periods and that the companies failed to adequately warn users about potential risks associated with excessive social media use.
The latest ruling allows the litigation to continue.
What the Appeals Court Decided
At the centre of the dispute is Section 230, a US law that generally protects online platforms from being treated as the publisher or speaker of content created by their users.
Meta and TikTok argued that the law should also protect them from lawsuits claiming that their platforms themselves were designed in ways that could make them addictive.
The companies sought to challenge a lower court decision that refused to grant them Section 230 protection at this stage of the proceedings.
The appeals court, however, did not rule that the companies could never rely on Section 230.
Instead, it concluded that they were attempting to bring the appeal before the litigation had reached a stage where such an appeal was permitted.
That distinction is important.
The decision does not amount to a final determination that Meta or TikTok are legally responsible for the allegations made by the plaintiffs. It means the companies must continue defending themselves in the underlying litigation rather than immediately taking the Section 230 dispute to the appeals court.
Meta Also Fails to Delay State Trial
The court also rejected Meta’s request to postpone a separate trial involving 29 state attorneys general.
That case accuses Meta of a range of practices involving young users, including allegedly collecting and using children’s data, designing its platforms to encourage prolonged engagement and misleading consumers about the safety of its services.
The trial was scheduled to begin shortly after the appeals court’s decision.
The states’ lawsuit represents another major legal challenge for Meta as governments across the United States increase scrutiny of social media’s impact on children and teenagers.
Meta has denied wrongdoing.
Why Section 230 Matters
Section 230 has played a central role in the legal development of the internet.
The law generally prevents websites and online platforms from being held liable for content posted by users in the same way that a traditional publisher might be responsible for material it publishes.
Over the years, technology companies have relied heavily on Section 230 to defend themselves against a wide range of claims.
The current social media cases, however, raise a different question.
Rather than focusing exclusively on content posted by individual users, plaintiffs are challenging the design and operation of the platforms themselves.
They argue that features such as recommendation systems, notifications and engagement mechanisms can encourage excessive use independently of what individual users post.
That distinction has become increasingly important in lawsuits involving social media and youth safety.
Thousands of Cases Move Forward
The lawsuits against Meta and TikTok are part of a much larger wave of litigation.
Cases have been filed by state governments, school districts, municipalities, parents and individuals.
The federal lawsuits have been consolidated before US District Judge Yvonne Gonzalez Rogers in Oakland, California.
Plaintiffs are seeking a range of remedies, including financial damages, penalties and other forms of compensation.
Many of the cases make similar allegations: that social media companies knew or should have known that certain platform features could encourage young users to spend excessive amounts of time online.
The plaintiffs also argue that companies did not provide adequate warnings about potential risks.
The technology companies have rejected those allegations.
Youth Mental Health at the Centre of the Cases
The legal battle comes amid a broader public debate about the relationship between social media and young people’s mental health.
Plaintiffs in the lawsuits claim that prolonged and compulsive social media use can contribute to problems including anxiety, depression and body-image concerns.
They also allege that certain platform designs can make it particularly difficult for young users to disengage.
Technology companies have disputed many of these claims and have argued that social media can provide important benefits, including communication, community and access to information.
The courts are now being asked to determine how existing laws apply to those competing arguments.
Meta Faces Additional Legal Pressure
The latest appeals court ruling comes after several other legal setbacks for Meta.
In New Mexico, the company has faced a separate case involving allegations concerning the safety of children on its platforms.
A state jury previously ordered Meta to pay hundreds of millions of dollars after finding against the company in litigation involving allegations that it misled consumers about the safety of its services.
A subsequent ruling found that Meta had created a public nuisance in the state and ordered the company to contribute an additional $567 million toward youth mental health initiatives and other measures.
Meta has denied wrongdoing and has said it intends to challenge adverse rulings.
The New Mexico proceedings are separate from the massive federal litigation now moving forward in California.
Another Major Trial Remains Ahead
The appeals court’s decision means the litigation will continue on multiple fronts.
The state attorneys general case involving Meta is moving toward trial, while a separate case involving school districts is also scheduled to proceed.
Attorneys representing school districts and other plaintiffs said the appeals court’s ruling removes an obstacle that could otherwise have delayed the proceedings.
For the plaintiffs, keeping the cases moving is important because they want to examine how Meta and other companies developed their platforms and whether executives understood the potential effects on younger users.
That could result in extensive examination of internal company documents, product-development decisions and research.
Other Technology Companies Are Also Involved
Meta and TikTok are not the only companies facing legal action.
Google and Snap are also defendants in hundreds of cases involving allegations concerning social media, children’s safety and mental health.
Google’s YouTube platform has faced many of the same questions about recommendation systems, engagement and the experiences of younger users.
The scale of the litigation makes the cases particularly significant for the technology industry.
A major ruling against one company could potentially influence how courts approach similar claims against other platforms.
The Legal Meaning of the Latest Decision
Despite the significance of the ruling, it is important not to confuse a procedural decision with a final judgment on the underlying allegations.
The appeals court did not determine that Meta or TikTok caused a youth mental health crisis.
It also did not conclude that the companies are liable for the claims made against them.
Instead, the court determined that the companies could not immediately appeal the lower court’s treatment of their Section 230 defence at this point in the proceedings.
That means the underlying cases can continue.
The companies will still have opportunities to make legal arguments as the litigation progresses, including arguments concerning Section 230 and other potential defences.
A Bigger Test for Social Media Regulation
The growing number of lawsuits could ultimately have implications far beyond Meta and TikTok.
If courts determine that certain claims based on platform design can proceed despite Section 230 arguments, social media companies could face greater exposure to lawsuits concerning how their products are built.
That could affect everything from recommendation algorithms and notification systems to age verification, parental controls and content-management tools.
Technology companies could also face greater pressure to demonstrate that they have taken reasonable steps to protect younger users.
At the same time, a final decision could help establish clearer boundaries around what Section 230 protects and what it does not.
What Happens Next?
For now, the legal battle is far from over.
Meta and TikTok must continue defending themselves against thousands of lawsuits while separate cases involving states and school districts move through the courts.
The companies continue to deny the allegations.
The plaintiffs, meanwhile, are seeking damages and other remedies while arguing that the design of major social media platforms contributed to serious problems among young users.
The latest appeals court decision ensures that those arguments will continue to be tested in court.
For the technology industry, the stakes are considerable.
The outcome could influence how companies design products for children and teenagers, how they use engagement-driven features and how much legal responsibility platforms may face for the consequences of those design choices.
As the lawsuits progress, the central question will become increasingly clear: where does the legal protection for online platforms end, and where does responsibility for the design of those platforms begin?
