The proposed bill introduces a new chapter, Chapter 39, to Title 6 of the Idaho Code, known as the "Uniform Public Expression Protection Act." This chapter aims to protect individuals' rights to free speech and expression in various governmental proceedings and matters of public concern. It defines key terms, outlines the scope of the law, and establishes a special motion for expedited relief that allows parties to seek dismissal of certain causes of action within a specified timeframe. The bill also includes provisions for stays of proceedings, hearings, proof considerations, and the dismissal of causes of action, as well as guidelines for appeals and the awarding of costs and attorney's fees.

Additionally, the bill emphasizes the importance of uniformity in application and construction across states that adopt similar legislation. It includes transitional provisions that specify the act will apply to civil actions filed on or after January 1, 2026, while ensuring that causes of action asserted before this date remain unaffected. The chapter also contains a severability clause, ensuring that if any provision is found invalid, the remaining provisions will still be enforceable. The act is set to take effect on January 1, 2026.
