The Supreme Federal Court of Brazil approved a final text expanding the civil liability of big-tech platforms for illegal content posted by third parties [1].
This decision shifts the legal burden toward social media companies, potentially increasing the number of lawsuits platforms face for user-generated content. It aims to protect victims of online harm by ensuring platforms are accountable for damages caused by illicit material [1].
According to the ruling approved on May 17, 2026 [1], platforms can now be held responsible for damages resulting from illegal content. However, the court included a specific exception: a provider may avoid liability if it can demonstrate a reasonable doubt regarding the illicit nature of the material [1].
Following this decision, big-tech companies filed nine resources against the ruling [3]. The court has since navigated the scheduling of these challenges. While some reports indicated the judgment of these resources was moved to a physical plenary session on May 29, 2026 [4], other records show Minister Dias Toffoli scheduled the judgment for Oct. 29, 2026 [3].
The STF's move comes as part of a broader effort to regulate the digital space in Brasília [2]. By establishing a framework for civil liability, the court seeks to balance the freedom of expression, and the necessity of protecting citizens from illegal online activity [1].
The final text serves as a pivot from previous standards where platforms often avoided liability unless they ignored specific court orders to remove content. Under the new rule, the presence of illegal content may trigger liability unless the platform can prove it acted with reasonable doubt [1].
“The STF approved a final text that expands civil liability for big-tech platforms”
This ruling marks a significant departure from the 'safe harbor' principles that have historically protected internet intermediaries. By introducing a standard of 'reasonable doubt' for liability, Brazil is creating a legal middle ground that forces platforms to be more proactive in content moderation while maintaining a narrow defense against clearly ambiguous cases.
