NetChoice Sues California: Challenges Social Media Warning Law

• NetChoice, representing Meta, Google, and TikTok, has sued California over its Social Media Warning Law.
• The law, effective January 1, mandates warning labels for users under 18 about social media's mental health risks.
• NetChoice argues the law violates the First Amendment by compelling private companies to disseminate state-mandated messages.
• The warnings must appear daily upon initial access, after three hours of use, and then hourly.
• California Attorney General Rob Bonta defends the law, citing research linking social media to youth mental health harms.

NetChoice contends that this requirement constitutes compelled speech, thereby infringing upon the First Amendment rights of its member companies.

NetChoice, a prominent internet trade association representing major technology companies like Meta, Google, and TikTok, has initiated legal action against the state of California. The organization filed a lawsuit in a Los Angeles federal court on Thursday, seeking to prevent the implementation of the state's new Social Media Warning Law. This legislation mandates that social media platforms display specific warning labels to users under the age of 18, highlighting the potential mental health risks associated with social media engagement. NetChoice contends that this requirement constitutes compelled speech, thereby infringing upon the First Amendment rights of its member companies.

The lawsuit specifically targets the California Social Media Warning Law challenge, arguing that the state is forcing private entities to disseminate a message on a "highly controversial topic" concerning the purported effects of social media use on its users. The trade group asserts that these warnings are not objective facts but rather "contested policy and scientific judgments" that the state is compelling private speakers to adopt. The outcome of this NetChoice lawsuit, involving tech giants Meta, Google, and TikTok, could significantly impact how states regulate online content and user safety, particularly regarding social media mental health warning labels. The law is slated to take effect on January 1.

California Governor Gavin Newsom officially signed the Social Media Warning Law into effect in October 2025, establishing a clear framework for how social media platforms must interact with their younger users. The statute dictates that social media platforms must periodically present a warning label to children and teenagers. This label is required to inform them that social media is linked to substantial mental health harms and has not been definitively proven safe for young individuals. The law's provisions are quite specific regarding the display of these social media mental health warning labels.

Platforms must ensure the warning is prominently shown when a user initially accesses the platform on any given day, unless the platform has already verified that the user is over 17 years old. Furthermore, the warning must reappear once a user has accumulated three hours of active use within that same day. Following this, the warning is to be displayed at least once for every subsequent hour of active use. These detailed requirements underscore California's intent to ensure that young users are consistently informed about the potential risks of their online engagement.

At the heart of NetChoice's legal challenge is the assertion that the California statute violates the First Amendment's prohibition against compelled speech. The trade association argues that by forcing its members to display specific warnings, California is essentially making these private companies act as a mouthpiece for the state's own message, which NetChoice characterizes as a matter of "contested policy and scientific judgments." This legal stance frames the issue as a fundamental question of First Amendment compelled speech social media rights for digital platforms.

Conversely, California Attorney General Rob Bonta, who was a key sponsor of the bill, has publicly defended the legislation. In 2025, Bonta highlighted a growing body of research that establishes a connection between young people's use of social media platforms and a range of serious adverse effects, including depression, anxiety, and suicidal ideation. The state's position is rooted in the protection of public health, particularly for minors, suggesting that the warnings are a necessary measure to inform and safeguard vulnerable users. NetChoice is seeking a court declaration that the statute is unconstitutional under the First Amendment and an injunction to prevent its enforcement, with legal representation provided by attorneys from Lehotsky Cohn in Washington D.C. and Benbrook Law Group in Newport Beach, California.

NetChoice maintains that its member companies, including Meta, Google, and TikTok, already implement various safeguards designed to protect young users. These measures reportedly include parental controls and robust content moderation systems. The organization points to efforts to restrict the publication of harmful content, such as violent and sexual material, bullying, harassment, and content that promotes body shaming or eating disorders. Additionally, NetChoice asserts that many of its covered websites actively promote positive and age-appropriate speech, including content that fosters a healthy self-image among young people.

This NetChoice lawsuit against California unfolds within a broader legal context where social media platforms face intense scrutiny. Meta, Google, and TikTok are currently embroiled in thousands of lawsuits across both state and federal courts, with plaintiffs alleging that these companies intentionally designed their platforms to be addictive for adolescents. In a significant development in September, Meta reached a settlement with 47 states, Washington, D.C., and several U.S. territories. This agreement involved a payment of up to $17.1 billion in civil penalties and a commitment to implement new safety features, addressing claims that its social media was deliberately made addictive to children. This ongoing legal pressure underscores the complex environment surrounding social media regulation and youth mental health.

Lawyers advising social media platforms or involved in content regulation should closely monitor this lawsuit, as its outcome will determine the enforceability of compelled speech requirements for platforms in California and could set a significant precedent for similar legislation regarding user safety and content warnings in other jurisdictions.
