House File 472, known as the Uniform Public Expression Protection Act, establishes legal protections for individuals exercising their rights to free speech, assembly, and petition in Iowa. The bill introduces several new sections that outline the scope of the law, which applies to civil actions based on communications in governmental proceedings or matters of public concern. It specifies that the act does not apply to actions against governmental units or employees acting in official capacities, nor to those primarily engaged in selling goods or services when the action arises from such sales.

The bill also provides a framework for expedited relief through a special motion to dismiss, allowing parties to seek dismissal of claims within sixty days of being served. It includes provisions for stays of proceedings during the motion process, requirements for court hearings, and guidelines for appeals. Additionally, the court is mandated to award costs and attorney fees to the prevailing party in these motions, ensuring that the law is applied broadly to protect constitutional rights while promoting uniformity across states that adopt similar legislation.
