The Brazilian Supreme Federal Court (STF) has concluded its judgment on the constitutionality of Article 19 of the Brazilian Internet Act (MCI) and established a new liability framework for digital platforms regarding user-generated content. The decision represents one of the most significant changes to Brazil’s digital regulatory environment since the enactment of the MCI in 2014.

Among the key points, the STF expanded the circumstances under which platforms may be held liable, adopted a notice-and-takedown approach for a broad range of unlawful content, created proactive monitoring and response obligations in cases involving serious crimes, and established new requirements related to transparency, governance, and local representation in Brazil.

The decision has significant implications for technology companies, social media networks, digital platforms, online service providers, and other participants in the digital ecosystem operating in the country.

To help understand these changes and their potential regulatory and operational impacts, our team has prepared a preliminary analysis of the ruling and the key points established by the STF.
