On August 14, 2025, the Supreme Court allowed Mississippi to enforce a law that regulates the use of social media by children. The decision drew national attention, as many states are considering similar rules. The case began when NetChoice, a trade group representing Facebook, X, YouTube, and other platforms, appealed against the law. The group asked the court to block the measure while the lawsuit continued, but the justices rejected the request. Justice Brett Kavanaugh explained that the law might later be declared unconstitutional but said this possibility was not a strong reason to stop it during the trial. The law was first passed in 2024, suspended by a federal judge, but later restored by the 5th Circuit Court of Appeals in July 2025. Supporters said the measure was needed to slow children’s growing use of social media, which researchers link to depression and anxiety.

The Mississippi Attorney General said the law could help protect children from sexual abuse, trafficking, and other online threats. State officials welcomed the ruling, noting it would allow closer study of the issue. NetChoice, which also includes companies such as Google, Meta, and Snap Inc., has filed lawsuits in several other states. Analysts said the case shows the conflict between protecting children online and defending freedom of expression.
