The South Carolina Public Expression Protection Act, introduced as H. 3305, aims to establish legal protections for individuals' communications in various governmental proceedings and matters of public concern. The bill adds Article 7 to Chapter 3, Title 15 of the South Carolina Code of Laws, defining key terms such as "governmental unit" and "person." It outlines the conditions under which a civil action can be asserted against a person based on their communication, while also specifying exceptions for governmental units and their employees acting in official capacities. The bill allows parties to file a special motion for expedited relief to dismiss such causes of action within sixty days of being served.

Additionally, the bill sets forth procedures for handling these motions, including stays on other proceedings and timelines for court hearings. It mandates that courts rule on motions within specified timeframes and provides for the awarding of costs and attorney's fees to the prevailing party. The act emphasizes the protection of rights guaranteed by the U.S. and South Carolina Constitutions, particularly regarding freedom of speech and assembly. It is set to take effect on June 1, 2025, and will apply to civil actions filed on or after that date.
