Brazil's Supreme Federal Court (STF) is facing an unprecedented institutional crisis after Justice Luiz Edson Fachin handed a complete dossier on fellow justice Alexandre de Moraes to the court's ministers just hours before a decisive vote scheduled for Tuesday. The move, reported by O Globo, has triggered the cancellation of a plenary session, suspension of rival rulings, and an escalating power struggle that is reverberating through the country's political landscape.

Judicial Maneuvering

According to multiple outlets, including Bloomberg and the Washington Post, Fachin, who presides over the STF, provided the full case file to the ministers overseeing the pending judgment on Moraes, a figure at the centre of investigations into alleged abuse of authority. The file hand‑over occurred on the eve of the court's deliberation, prompting the STF to abruptly cancel its scheduled session, as reported by The Seattle Times, The Hour and several regional papers.

The internal dispute escalated when Fachin suspended several rulings issued by other justices, a step described by the Financial Express and the Courthouse News as a “suspension of rival rulings” amid a broader power struggle. The move has been framed by analysts as an attempt to consolidate control over the court's agenda ahead of the October elections.

Political Fallout

Political figures quickly linked the judicial turmoil to President Luiz Inácio Lula da Silva’s waning popularity. Edson "Edinho" Silva, a close adviser to Lula, told Poder360 that the crisis is eroding the president’s standing in opinion polls. Bloomberg corroborated the trend, noting a recent surge in support for former President Jair Bolsonaro as the STF crisis weighs on Lula’s re‑election prospects.

Right‑wing candidates have seized on the controversy, making the STF dispute a centerpiece of their campaign messaging, according to Valor International. An evangelical justice, identified by Marketscreener as a key influence, is also shaping the narrative, further polarising the electorate.

Lula has called for greater transparency in the so‑called "Master" case involving Moraes, urging the court to disclose all documents related to the investigation, as reported by Valor International. The president’s appeal underscores the broader concern that the judiciary’s internal conflicts may undermine public confidence in democratic institutions.

The Economist warned that "the STF has become a threat to democracy in Brazil".

Economist commentary echoed across international media, including CNN Brasil and The Washington Post, which described the court’s actions as potentially destabilising for Brazil’s democratic order. The criticism aligns with observations from The New York Times and other outlets that the STF’s internal feuds risk eclipsing its constitutional role.

As Brazil approaches a tightly contested presidential race, the Supreme Court’s crisis is reshaping the political calculus. Analysts suggest that the dispute could amplify voter volatility, with the judiciary’s credibility now a decisive factor in the October election dynamics.

While the STF works to restore procedural normalcy, the episode highlights the fragile balance between Brazil’s judicial authority and its democratic processes. Observers warn that unresolved tensions within the court could have lasting repercussions for the nation’s governance and the integrity of upcoming elections.
