New presidential decrees significantly increasing the regulatory burden and liability for major internet platforms in Brazil went into effect on July 20, 2026, immediately triggering a political and legal fight from the opposition in the National Congress. Decrees 12.975 and 12.976 modify the regulatory framework for the country’s *Marco Civil da Internet* (Internet Civil Framework), shifting the environment for global platforms like Meta, Google, and TikTok from a largely hands-off approach to one that requires financial-sector-like governance, risk management, and compliance standards. The rules impose a sweeping "duty of care," requiring platforms to implement proactive measures against a defined list of serious crimes, including terrorism, digital fraud, and online violence against women.
