Fifth Circuit Holds Section 230 Preempts Texas Social Media Monitoring and Filtering Mandates

The Fifth Circuit Court of Appeals, in a 2-1 decision in Computer & Comm. Industry Ass'n v. Paxton, ruled that Section 230 of the Communications Decency Act preempts key provisions of Texas House Bill 18. The law required digital service providers (DSPs) to implement strategies to prevent minors' exposure to harmful material, including content related to suicide, self-harm, substance abuse, and sexual exploitation. The court found that these monitoring and filtering requirements effectively hold DSPs liable for their editorial decisions—such as whether to publish, withdraw, or alter content—which is precisely the type of publisher liability that Section 230 immunizes. The ruling distinguished this from age-verification requirements, which were not preempted. The decision reinforces broad Section 230 immunity for platforms against state-imposed content moderation obligations.
