Brazil’s highest court may be acting within the law. It is not acting within the bounds of good judgment.
Eighteen days before Brazilians choose their next president, the Supreme Court ordered the brother of one of the two finalists to prison. The man who signed the order, Justice Alexandre de Moraes, was also the man the brother had been convicted of trying to pressure.
You do not need a law degree to see the problem. Justice is not only about being fair, it is about being seen to be fair, and on that test Brazil’s top court has just failed in front of the whole world.
What Happened
Eduardo Bolsonaro, a former federal deputy and son of former president Jair Bolsonaro, has lived in the United States since early 2025. In June 2026, a Supreme Court panel sentenced him to four years and two months for “coercion in the course of proceedings,” finding that he had lobbied Washington for sanctions and tariffs to pressure the justices trying his father.
The panel rejected his appeal unanimously on 18 September, and the sentence became final on 3 October, the day before the first round of the presidential election. On Wednesday, 7 October, Moraes signed the order for his arrest, his entry in the national prison register and the cancellation of all his Brazilian passports, and the court made it public the next day.
A Judge in His Own Case
The oldest rule of justice fits on a postcard: no one should judge his own case. The Romans called it nemo iudex in causa sua, and every democracy has some version of it.
Eduardo’s alleged crime was lobbying for punishment of Brazilian judges, above all Moraes, whom Washington placed under Global Magnitsky sanctions from July to December 2025. When the federal public defender asked in June for Moraes to step aside as the case’s alleged target, Moraes refused, arguing that the victim of the crime is the administration of justice rather than the judges, and the panel agreed.
That may be a sound legal answer. It is not a convincing one to a voter who sees the judge whose sanctions were at stake signing the arrest order.
A Panel of the President’s Choices
The rest of the bench does not ease the worry. Of the four justices who convicted Eduardo, three were appointed by President Luiz Inácio Lula da Silva, the man now fighting Eduardo’s brother for the presidency.
Cristiano Zanin was Lula’s personal lawyer, Flávio Dino was his justice minister, and Cármen Lúcia was appointed by Lula in 2006, while Moraes was appointed by President Michel Temer in 2017. None of this proves bias, but it does entitle a fair-minded voter in São Paulo or Ohio to raise an eyebrow.
Prison for a Lobbying Campaign
What Eduardo did was loud, and many Brazilians found it unpatriotic: he asked a foreign government to punish his own country’s judges and, through tariffs, its economy. But lobbying politicians in another capital is political activity, and turning it into a prison sentence sets a precedent that any future government could abuse against its critics.
Washington has already taken sides. In June, a State Department spokesperson described the conviction as persecution and legal manipulation of Brazil’s opposition, according to Brazilian media, which means this case now sits at the heart of relations between the hemisphere’s two largest democracies.
The Timing Is the Problem
The court’s defenders have a point: the order followed the usual sequence. When Jair Bolsonaro’s conviction became final in November 2025, Moraes ordered him to start his sentence the same day, and Eduardo’s case simply moved the same way.
But routine is exactly what should have bent here. In the United States, the Justice Department follows an unwritten custom, often called the 60-day rule, of avoiding dramatic steps that could sway an election in its final weeks.
Waiting until after 25 October would have cost Brazil’s court nothing. Eduardo lives in the United States, holds a US green card and cannot be arrested there without an extradition process, so the order changes little except the headlines in the middle of a presidential runoff.
What This Is Not
We see no evidence that anyone in Lula’s campaign ordered this decision, and we do not claim it. The conviction dates from June, and the court’s calendar was set long before the first round.
Nor has the order hurt the brother in the race. Polymarket gave Flávio Bolsonaro an 84.8% chance of winning on 5 October and 85.8% on 9 October, after the order, and the episode may even strengthen his message that his family is being persecuted.
What Brazil Should Do
Brazil’s Supreme Court is powerful because Brazilians and foreign investors trust it to stand above the fight. That trust is the court’s only real capital, and it is spending it fast.
Two simple rules would help. Judges should step aside from any case in which they are the alleged target, and courts should avoid dramatic steps against candidates and their close relatives in the final weeks of a national election; neither rule weakens the rule of law, and both protect it.
What Prediction Markets Say
On Polymarket, Flávio Bolsonaro was priced at 85.8% to win the runoff on 9 October at 1:25 a.m. ET, against 13.5% for Lula, with more than US$178 million traded. Kalshi, the US exchange regulated by the CFTC, showed 88% for Flávio.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
