In Brazil, regulatory change happens in the open. Live-streamed court sessions, algorithmic systems, private rules, and media narratives intersect, transforming the idea of accountability into something negotiated, contested, and performed. Law and code are meeting in real-time—and how Brazil handles this fusion may influence governance models far beyond its borders.
The End of an Era: The Fall of Article 19
In June 2025, the Brazilian Supreme Court (STF) struck down part of Article 19 of the Marco Civil da Internet, ending the judicial “notice-and-takedown” system that had governed the last decade. Moving forward, platforms can be held liable even without a court order if they fail to remove “manifestly illegal” content following extrajudicial notification.
Reglab conducted an unprecedented mapping of this case, analyzing:
-
87 legal documents
-
56 stakeholder positions
-
397 distinct arguments
Our research revealed an unlikely alliance: civil society and academia aligned with tech companies to defend Article 19 as a democratic safeguard against “over-moderation.”
The Supreme Court as a Media Ecosystem
Why did the Court move in the opposite direction of this consensus? To understand this, one must recognize that in Brazil, the Supreme Court is a central part of the media ecosystem.
STF trials are broadcast live on TV, radio, and YouTube. Every argument becomes public theater—subject to commentary, polarization, and digital amplification. Reglab’s strategic briefs, featuring real-time discourse analysis, showed that Justices frequently echo public anxieties regarding hate speech and disinformation, often resorting to moral and symbolic language rather than purely technical legal reasoning.
The Economic Impact: “The Price of Moderation”
The shift in platform responsibility isn’t just a legal theory; it has massive economic consequences. Reglab’s study, The Price of Moderation, used a pioneering econometric approach to estimate the impact:
| Projection Metric | Estimated Impact (by 2029) |
| New Lawsuits | Up to 243,000 |
| Additional Judiciary Costs | US$ 48 Million |
Strategic Influence:
Released before the trial resumed, our research reached an estimated audience of 20 million people across 48 media outlets. It directly influenced the debate by helping defeat the “Strict Liability” (responsabilidade objetiva) theory during the first phase of the trial—a theory that could have tripled the projected costs.
A Hybrid Architecture for the Future
The next phase will test the resilience of this model. What is emerging in Brazil is not a simple copy of the European Digital Services Act (DSA). Instead, Brazil is developing a hybrid architecture that combines:
-
Constitutional Oversight
-
Self-Regulation
-
High-Volume Litigation
Accountability will be co-produced by courts, code, and corporations—a dynamic of checks, balances, and constant adaptation.
The Global Stakes: As the largest digital market in Latin America and a leader in the BRICS, Brazil’s governance model now dictates compliance, legal, and Trust & Safety strategies for the entire region. The risks are high—fragmented litigation and expensive system redesigns—but so are the opportunities for evidence-based policy formulation.
