Civil procedure: civil actions; lawsuits for exercising rights to free expression; provide protections against. Creates new act.

SB 57 creates the "Uniform Public Expression Protection Act" to shield individuals and organizations from abusive lawsuits targeting free speech. It directly affects people sued for expressing views on public issues, such as through protests, social media, or public comments about government actions. Key provisions require courts to quickly dismiss such cases (within 60 days) by staying discovery, shifting the burden to prove the lawsuit is valid to the plaintiff, and imposing sanctions for frivolous claims. The law excludes lawsuits involving government employees, civil rights claims, or commercial speech about goods/services, focusing solely on protecting constitutional expression rights.
