Social Media Companies Just Got a Much Bigger Legal Problem as Addiction Lawsuits Clear Major Hurdle

More than 3,000 lawsuits accusing Meta, Google, TikTok and Snap of harming young users through allegedly addictive platform designs can move forward after a U.S. appeals court rejected the companies’ attempt to halt the cases.

The 9th U.S. Circuit Court of Appeals ruled Monday that the companies could not immediately challenge a lower-court decision involving Section 230 of the Communications Decency Act, which generally protects online platforms from liability for user-generated content.

The ruling does not decide whether the companies are liable. It allows the lawsuits to continue.

Appeals Court Rejects Early Challenge

The companies had argued that Section 230 protected them from claims tied to content appearing on their platforms. The plaintiffs argued that their cases concern the companies’ own product designs and business practices, including features they say encourage prolonged or compulsive use.

The appeals court declined to hear the companies’ challenge at this stage, finding that the appeal was premature. The decision leaves the underlying lawsuits in federal court. 

The litigation includes claims brought by young people and their families, school districts and government entities. The cases have been consolidated in federal court in California.

The plaintiffs allege that features such as recommendation systems, notifications and other engagement tools were designed in ways that can encourage excessive use among children and teenagers. The companies dispute the allegations.

Section 230 Becomes A Central Issue

Section 230 has long been a key legal protection for internet companies. It generally shields online services from liability for material posted by their users.

The lawsuits raise a narrower question: whether that protection can be used when plaintiffs claim that the companies themselves created harmful product features. The appeals court has not ruled that Section 230 does not apply to those claims. Its decision instead leaves the cases in place while the litigation proceeds.

That distinction is reflected in the status of the cases. The ruling allows plaintiffs to pursue their claims, but they still have to prove that the companies’ conduct caused legally compensable harm.

Meta Faces Separate Youth Cases

Meta is also defending separate litigation over alleged harm to young users. A New Mexico court ordered Meta to pay $567 million into a state fund for youth mental health services after finding that the company had operated its platforms as a public nuisance and failed to adequately protect children. Meta has said it will appeal.

In March, a Los Angeles jury found Meta and Google’s YouTube liable in a separate case brought by a young woman who alleged that the platforms were designed to be addictive. The jury awarded $6 million in damages.

Those cases are separate from the 9th Circuit litigation.

But they form part of a growing body of lawsuits testing whether social media companies can face liability over the design and operation of their platforms, rather than solely over content posted by users.

Thousands Of Claims Remain

The 9th Circuit ruling does not send the more than 3,000 cases to trial immediately. Individual claims will continue through pretrial proceedings. Some may settle, while others could proceed to trial.

TikTok and Snap have already settled some individual cases involving allegations of social media addiction. Other claims against the companies remain active.

The latest ruling keeps the larger litigation alive and leaves the companies to continue defending allegations that their product designs contributed to harmful use among young people. The central legal question will now be tested through the individual cases: whether the alleged design choices can support liability and whether the companies can ultimately prevail on Section 230 or other defenses.
