Brazil's Supreme Federal Court has ordered a formal investigation into the alleged diversion of parliamentary funds to cultural projects, including a feature film about former President Jair Bolsonaro. The probe was triggered by a complaint filed earlier this year by lawmaker Tabata Amaral of the Brazilian Socialist Party, with the order issued by Justice Flavio Dino on Friday, 16 May.

What the Complaint Alleges

According to the complaint, several lawmakers from Bolsonaro's Liberal Party allegedly transferred a combined 2.6 million reais (approximately 514,000 US dollars) from parliamentary amendments, potentially routing public funds toward electoral marketing and audiovisual content linked to Bolsonaro. The former president is currently serving a sentence for an attempted coup.

Amaral alleged that these parliamentary amendment funds — ordinarily meant for public welfare projects — may have been repurposed for political and promotional content. Brazilian authorities are now working to determine whether the transfers constituted an illegal use of public budget resources.

The 'Dark Horse' Film Connection

At the centre of the controversy is a planned feature film titled 'Dark Horse', reportedly intended to chronicle Bolsonaro's life. Separately, media reports indicate that Senator Flavio Bolsonaro, the former president's son and a reported presidential hopeful, sought 130 million reais (approximately 25 million US dollars) from a private banker currently jailed on fraud charges, reportedly to fund the production.

The case remains under seal while evidence is being gathered, according to court records.

Bolsonaro's Legal Battles

This probe adds to an already substantial legal burden on the Bolsonaro camp. In September last year, the Supreme Federal Court sentenced Jair Bolsonaro to 27 years and three months in prison for leading an attempted coup — one of the most significant convictions of a former head of state in Brazil's democratic history.

Just last week, on 9 May, the court also temporarily suspended a law that could have shortened prison terms for individuals convicted in connection with the January 8, 2023 attacks on government buildings in Brasilia. Justice Alexandre de Moraes, assigned to review the law's constitutionality, issued the suspension, stating it was necessary to ensure legal certainty while the court assessed whether the legislation was compatible with Brazil's constitution.

Broader Implications

The parliamentary amendment system — known in Brazil as 'emendas parlamentares' — has long been scrutinised for its susceptibility to misuse. Critics argue the system gives individual lawmakers near-unchecked discretion over public funds, creating conditions for political patronage. This case, reportedly the first to directly link such funds to a former president's promotional content, could set a precedent for how the court polices the intersection of public finance and political communication.

With the fund-diversion probe now formally open and the 'Dark Horse' film financing under scrutiny, the legal pressure on Bolsonaro's political network is set to intensify in the months ahead.
