Brazil's Supreme Court Moves to Conclude Seven-Year Fake News Inquiry
The Prosecutor General recommends closing the landmark investigation, citing the exhaustion of its original mandate.
1Inquiry Reaches Final Stage
Brazil's Supreme Court is nearing the formal closure of the 'fake news' inquiry, a seven-year investigation initiated in 2019. Prosecutor General Paulo Gonet officially recommended archiving the main case, known as the 'mother inquiry.' Supreme Court President Edson Fachin, who assumed control in September, is expected to finalize this decision shortly.
2Institutional Shift in Leadership
The investigation was originally led by Justice Alexandre de Moraes after being opened by former President Dias Toffoli. In September, Justice Fachin transferred the case to the Court's presidency to ensure institutional stability. This transition followed internal pressures and controversies regarding the scope of the probe, which had expanded significantly over time.
3Rationale for Proposed Closure
The Prosecutor General argues that the inquiry has fulfilled its primary function of protecting the Court's legitimacy against threats. Gonet emphasizes that the investigation's duration must respect constitutional guarantees regarding reasonable trial lengths. While the main inquiry closes, over 100 individual procedures will continue to be analyzed on a case-by-case basis.
4Data Sensitivity and Secrecy
The PGR insists that the 12,000 pages of evidence must remain under seal. These documents contain sensitive strategic information regarding the physical and operational security of high-ranking officials. The prosecution warns that public disclosure could expose vulnerabilities, as the files include private banking, fiscal, and personal data of numerous investigated individuals.
5Scope and Legal Controversies
Initially focused on threats against Supreme Court justices, the inquiry's scope widened over seven years to include various digital misinformation campaigns. It involved police operations, social media blocks, and search warrants. The investigation faced significant criticism from legal entities like the Brazilian Bar Association, which questioned its broad, evolving legal mandate.
6Recent Judicial Precedents
Justice Fachin recently dismissed a request to include former prosecutor Deltan Dallagnol in the inquiry. This decision followed a shift in the Court's understanding of privileged forum rules. The case, initially sent to lower courts, returned to the Supreme Court in March 2025, where the PGR successfully argued for its dismissal.
7Managing Derivative Procedures
While the main inquiry is set to close, the Court is actively managing over 100 related petitions and preliminary investigations. Justice Fachin has already archived at least nine of these secondary cases. Remaining procedures will be reviewed individually, ensuring that previous judicial rulings remain intact while preventing further unnecessary procedural expansion.
8Legacy of the Investigation
The conclusion of this inquiry marks a symbolic turning point for the Supreme Court. By transitioning from a centralized, long-term investigation to individualized legal procedures, the Court aims to restore institutional normalcy. The focus now shifts toward maintaining the confidentiality of the gathered evidence while finalizing the remaining pending legal actions.
