PL 2338/2023 – proposed AI legal framework ('Marco Legal da IA')

Summary

Senate bill PL 2338/2023 (author Rodrigo Pacheco) would set Brazil's general legal framework for AI. The Senate approved a substitute text on December 10, 2024, and sent it to the Chamber of Deputies on March 17, 2025. The approved text follows a risk-based approach that distinguishes excessive-risk and high-risk systems, protects copyright, and creates a National AI Regulation and Governance System (SIA) coordinated by the data protection authority (ANPD). In the Chamber the bill sits with a special committee and, as of October 2026, still awaits the rapporteur's report; no plenary vote has taken place.
