Supreme Federal Court President Edson Fachin has ordered the closure of Brazil’s Fake News Inquiry, ending the main investigation opened in 2019 into threats, disinformation and attacks directed at the Court and its justices. He accepted Prosecutor-General Paulo Gonet’s assessment that the inquiry’s specific purpose had been exhausted.¹

Fachin’s ruling draws a line between ending the original proceeding and undoing what followed from it. The closure does not invalidate evidence, convictions, agreements or autonomous criminal cases. The Court identified 104 linked procedures, which are to be reviewed individually; sensitive personal, banking, tax and business information will remain protected before the principal case file is opened to public access.¹

For supporters of the inquiry, its long duration reflected an unusually sustained challenge to the Court’s ability to operate independently. Gonet argued that threats against justices and their families, coordinated disinformation campaigns and calls to close the Court threatened both judicial independence and constitutional order.¹ Fachin likewise said the decision did not erase the inquiry’s institutional rationale or its role in protecting the Court at a singular moment in Brazil’s republican history.²

Yet Fachin also stressed that investigations are instruments, not permanent structures. “Investigations, precisely because they are instrumental, must find an end,” he wrote, adding that the protection of democratic institutions must occur within constitutional guarantees.²

That limitation echoes long-running objections from right-leaning critics, who questioned the inquiry’s opening by the Court itself, the designation of Justice Alexandre de Moraes without the usual random allocation, and measures affecting media outlets, social-media accounts and political figures. One account of the inquiry described the debate as involving freedom of expression, due process and the limits of the Court’s authority.³

Commentator Rodrigo Constantino summarized that view after the ruling: “too little, too late.”Rodrigo Constantino (Rconstantino)⁴ The closure therefore settles the status of the original inquiry, but not the broader dispute over how far courts should go in defending democratic institutions.
