Brazil's Supreme Court Investigates Senate Candidate Flavio Bolsonaro Over Film Inquiry

Brazil's Supreme Court (STF) has formally named Senator Flavio Bolsonaro (PL-RJ) as a subject of investigation in a federal inquiry examining the production of a film titled "Dark Horse," according to Folha de S.Paulo. The decision was issued by STF Justice Andre Mendonca on July 22, 2026.

Flavio Bolsonaro is a current senator representing Rio de Janeiro and is running as a presidential candidate in Brazil's 2026 general election. He is the son of former President Jair Bolsonaro, who is currently imprisoned following a judicial finding that he led an attempt to overturn the results of the 2022 presidential election on January 8, 2023, according to Folha de S.Paulo.

The "Dark Horse" inquiry, as reported by Folha de S.Paulo, centers on the production of a film about Jair Bolsonaro. Federal Police (Policia Federal) are conducting the investigation under STF supervision. The specific allegations under examination have not been fully disclosed in published court filings available at the time of publication. What would clarify the scope of the charges is the full text of Justice Mendonca's July 22 order, which had not been made publicly available in its entirety as of the date of this report.

Flavio Bolsonaro's candidacy places him at the center of Brazil's political opposition heading into the 2026 election cycle. His father's conviction and imprisonment represented a significant rupture in Brazilian political history, as Jair Bolsonaro had refused to accept the results of the October 2022 election won by Luiz Inacio Lula da Silva, according to prior reporting by multiple Brazilian news outlets.

The STF has been the primary judicial body overseeing prosecutions related to the January 8, 2023 events, during which supporters of Jair Bolsonaro stormed and vandalized the buildings housing Brazil's Congress, Supreme Court, and the presidential palace in Brasilia. Those prosecutions have proceeded across multiple cases and defendants over the past three years.

The involvement of Justice Andre Mendonca in this specific inquiry is notable because Mendonca was originally appointed to the STF by Jair Bolsonaro in 2021, according to Brazilian congressional records. His role as the presiding justice in the investigation of Flavio Bolsonaro is a matter of public court record.

Flavio Bolsonaro attended a campaign event in the Copacabana neighborhood of Rio de Janeiro, as documented in photographs published alongside Folha de S.Paulo's reporting. No public statement from his campaign responding to the investigation had been published by Folha de S.Paulo as of the time of this report.

Brazil's electoral authority, the Tribunal Superior Electoral (TSE), sets rules governing whether criminal investigations or convictions affect a candidate's eligibility to run for office. Whether the current STF inquiry carries any formal implications for Flavio Bolsonaro's 2026 candidacy under existing Brazilian electoral law was not addressed in the available source material. The applicable legal standard would be determined by the TSE and relevant provisions of Brazil's Clean Record Law (Lei da Ficha Limpa).

The 2026 Brazilian presidential election is scheduled to be held in October of that year. President Lula is eligible for re-election under Brazil's constitution, which permits two consecutive terms. The formal opposition field, its composition, and polling data were not detailed in the source material reviewed for this report.

The investigation represents one of several legal proceedings arising from the broader political events surrounding the January 2023 attack on federal institutions in Brasilia, which Brazilian prosecutors and courts have characterized as a coordinated effort to prevent the transfer of power. The status of all related proceedings is subject to ongoing judicial action at the STF.
