On 17 July 2024, an appeal was filed challenging the district court's decision to deny a preliminary injunction against AB 587. The appeal argues that the district court erred in its assessment of AB 587's impact on First Amendment rights and the burden it places on social media companies' speech and editorial decisions. Previously, the U.S. District Court for the Eastern District of California denied X Corp.'s request to block California Assembly Bill 587. X Corp. claimed the law, which mandates social media companies to post terms of service and report on content moderation, violated the First Amendment and was preempted by Section 230 of the Communications Decency Act. The court ruled that the law's requirements were lawful, involved commercial speech, and were not preempted by federal law, leading to the denial of X Corp.'s motion for an injunction.
