Brazilian Supreme Court concludes landmark trial reshaping ISPs' civil liability regime for third-party content

On June 26, the Brazilian Supreme Court (STF) concluded the trial on the constitutionality of Article 19 of the Brazilian Internet Act (Law #12,965/2014 – “MCI”), ruling the Article partially unconstitutional.

Article 19 of the Brazilian Internet Act had established that internet service providers (ISPs) could only be held liable for damages arising from third-party content after failing to comply with a specific court order mandating its removal (judicial-takedown), subject to limited exemptions under the notice-and-takedown regime. In a groundbreaking decision, the Supreme Court reshaped this civil liability regime and imposed several regulatory requirements to ISPs operating in Brazil.

The Supreme Court explicitly stated that current internet legislation lacks sufficient safeguards for constitutionally protected rights and democratic principles. Congress was criticized for failing to create new regulations, and the Court declared that, until new legislation is passed, ISPs’ civil liability for damages arising from third-party content regime will vary depending on the content involved:

Type of content

Regime

Content involving crimes and illicit acts in general; and non-authentic accounts

ISPs will be held liable if they do not remove infringing content after a mere notification requesting to take it down (notice-and-takedown)

Content involving crimes against honor

ISPs will only be held liable after non-compliance with a specific court order determining the removal of the infringing content (judicial-takedown)

Paid advertisements and promoted content or artificial distribution networks, chatbots, or robots

ISPs are presumptively liable for damages arising from such content, regardless of notification or court order, and may only be exempted when there is proof that they diligently and timely took down the infringing content

Content involving serious crimes1

ISPs have a duty of care to takedown content involving serious crimes. Failure to adopt adequate measures in this regard will be considered a systemic flaw and will subject ISPs liable for damages arising from such content.

Isolated instances of illicit content are insufficient to trigger civil liability under this item. In this case, the notice-and-takedown regime shall apply.


These rules do not apply to (a) e-mail service providers, (b) providers primarily offering closed meetings by video or voice, (c) providers of instant messaging services, exclusively with regard to interpersonal communications, protected by the confidentiality of communications. These services remain under the original Article 19 civil liability regime (judicial-takedown). Marketplaces’ liability regime is as provided by consumer legislation.

In addition, the ruling has also established several regulatory requirements for ISPs operating in Brazil, such as:

• Develop self-regulation that includes notification systems, due process, and annual transparency reports;

• Offer accessible customer service channels for both users and non-users;

• Publicly disclose and regularly review their terms of service and content policies;

• Establish and maintain local presence and a representative in the country, with clear and accessible contact information published on their websites.

This decision marks a turning point in Brazil’s digital regulatory landscape. ISPs will now need to strengthen content moderation practices or risk civil liability. Compliance efforts will be essential moving forward.
