The Uniform Public Expression Protection Act aims to safeguard actions related to freedom of speech and assembly, providing expedited relief and the possibility of attorney fees in civil actions. The bill outlines the scope of its application, which includes communications in governmental proceedings and matters of public concern, while excluding claims against governmental units or those primarily engaged in selling goods or services. It establishes a process for parties to file a special motion for expedited relief within 60 days of being served with a complaint, allowing for a stay of proceedings during the motion's consideration.

Additionally, the Act mandates that courts rule on these motions within a specified timeframe and provides for the awarding of costs and attorney fees to the prevailing party. It emphasizes the need for broad construction to protect constitutional rights and aims for uniformity in application across states. The bill includes an immediate effective date and applicability to civil actions filed after its passage, ensuring that it does not retroactively affect existing causes of action.
