Brazil’s Supreme Court has issued a landmark ruling establishing a new framework for social media regulation in the country, requiring platforms to implement content moderation measures within 90 days. The unanimous decision was reached after months of public hearings and expert testimony.

The ruling mandates algorithmic transparency, age verification systems, and the establishment of a dedicated regulatory body with enforcement powers. Non-compliant platforms face potential suspension of operations in the Brazilian market, which represents over 170 million internet users.

The decision has been closely watched globally as a potential template for social media governance in emerging economies. Legal scholars note that the ruling draws on elements of both the EU’s Digital Services Act and unique provisions tailored to Brazil’s specific challenges.

Major tech companies have issued measured responses, with most indicating willingness to engage with the new requirements while expressing concerns about implementation timelines and technical feasibility of certain provisions.

Civil society groups in Brazil have largely praised the ruling, arguing that social media platforms have enabled the spread of disinformation that has undermined democratic institutions. Free speech advocates, however, caution that government oversight of content moderation could create risks of censorship.
