Lula's annulled convictions: how Brazil's courts reversed them
Brazil's Supreme Federal Court annulled the corruption convictions of Luiz Inácio Lula da Silva in 2021. It did so in a series of rulings between March and June, on two separate legal grounds: the court that tried him lacked jurisdiction, and the judge in one case was found to have been biased. The rulings did not decide whether Lula was guilty or innocent. This article explains what the courts decided, how the reversal happened and what it means for the question of a miscarriage of justice.
The original convictions
The cases grew out of Operation Car Wash (Lava Jato), the investigation into bribery linked to the state oil company Petrobras. They were heard by the 13th Federal Court in Curitiba, where Judge Sergio Moro presided. In the best-known case, concerning a beachfront triplex apartment in Guarujá, Lula was convicted at first instance in 2017 and sentenced to 9 years and 6 months. On appeal in 2018, a regional federal court increased the term to 12 years and 1 month. The Superior Court of Justice later reduced it to 8 years and 10 months.
Lula was also convicted in a second case, concerning a country property in Atibaia. He has always denied wrongdoing and described the prosecutions as politically motivated.
Prison and release
Lula began serving his sentence in Curitiba in April 2018. The conviction made him ineligible for that year's presidential election. He was released on 8 November 2019, after about 580 days in custody, when the Supreme Federal Court ruled that a prison sentence could not begin while appeals were still available. That decision concerned the timing of imprisonment. It did not undo the convictions.
Leaked messages and the question of impartiality
In June 2019 the news outlet The Intercept began publishing private messages between Moro and the Car Wash prosecutors, including lead prosecutor Deltan Dallagnol. Critics said the exchanges showed the judge advising and coordinating with the prosecution, which Brazilian judicial rules do not allow. After the 2018 election Moro had also become justice minister in the government of Jair Bolsonaro, Lula's rival, which the defence cited as further evidence of bias.
The authenticity and legal weight of the messages were contested. Supporters of the investigation argued that the material was obtained unlawfully and did not show that the evidence against Lula was unsound.
The 2021 rulings
Jurisdiction
On 8 March 2021, Justice Edson Fachin granted a habeas corpus petition, a legal challenge to the lawfulness of a detention or prosecution. He found that the Curitiba court was not the proper forum, because the alleged offences had no sufficient link to the Petrobras contracts that gave that court its authority. He annulled the convictions and sent the cases to the federal courts in Brasília. Lula's political rights were restored as a result. The full court upheld the ruling by eight votes to three on 15 April 2021.
Bias
Lula's lawyers had separately asked the court to find Moro partial. On 23 March 2021, the court's Second Panel agreed in the triplex case, by three votes to two. The full court confirmed that decision by seven votes to four on 23 June 2021. On 24 June, Justice Gilmar Mendes extended the finding to the other two Curitiba cases against Lula, ruling that evidence gathered in them could not be used. Fresh proceedings would have had to begin from the start.
| Date | Decision |
|---|---|
| 8 March 2021 | Fachin annuls the convictions for lack of jurisdiction |
| 23 March 2021 | Second Panel finds Moro biased in the triplex case, 3–2 |
| 15 April 2021 | Full court upholds the jurisdiction ruling, 8–3 |
| 23 June 2021 | Full court confirms the finding of bias, 7–4 |
| 24 June 2021 | Mendes extends the ruling to two further cases |
Later developments
In 2022 the United Nations Human Rights Committee also found that Moro had lacked impartiality in the cases against Lula. In 2023 a Supreme Federal Court justice went further, invalidating evidence drawn from a leniency agreement with the construction firm Odebrecht on the ground that it had been unlawfully obtained. His reasoning described Lula's imprisonment as a serious judicial error. That ruling was a single justice's decision and drew criticism from supporters of the original investigation.
What the rulings did and did not decide
Three points matter when assessing the case as a possible miscarriage of justice.
- No finding on guilt. Annulling a conviction for jurisdiction or bias returns a defendant to the position of someone not convicted. It is not an acquittal on the merits.
- Procedural fairness. The central finding was that the process fell short of the standard of an impartial tribunal. That is a separate question from the strength of the underlying evidence.
- Contested views. Lula's supporters regard the outcome as the correction of a politically driven prosecution. Critics argue that the cases were closed on technical grounds before the allegations could be tested at a new trial.
No conviction in these cases has stood against Lula since the annulments.
Why the case matters
The episode is often cited in debates about the limits of anti-corruption campaigns and the duty of judges to remain neutral. It also shows how a legal system can correct itself, although in this case the correction came after Lula had spent more than a year and a half in custody and missed an election. Lula went on to win the presidency in 2022 and, according to recent reports, was re-elected in October 2026.
