A panel of five justices from Brazil’s Supreme Federal Court on Thursday sentenced former president Jair Bolsonaro to 27 years and three months in prison after convicting him of orchestrating a plot to remain in power despite losing the 2022 presidential election.

The panel found Bolsonaro guilty on five counts, with four of the five justices voting to convict and one dissenting. The verdict and sentence came on the same day; Bolsonaro, who has been living under house arrest in Brasília, did not attend the proceedings and may file appeals seeking to overturn the convictions or to keep him confined to house arrest rather than serving a prison term.

The justices concluded that Bolsonaro led a conspiracy aimed at keeping him in power after his defeat to Luiz Inácio Lula da Silva in the 2022 presidential vote. Prosecutors and judges cited efforts to pressure the armed forces and mobilize supporters to reject the election outcome, conduct that culminated in a broader assault on democratic institutions in early 2023 by some of the former president’s followers.

Bolsonaro, 70, has long denied wrongdoing and previously described the legal process as politically motivated. After the sentence was announced, U.S. President Donald Trump said he was "very unhappy" with the conviction and described Bolsonaro as "outstanding." Trump also likened the Brazilian proceedings to attempts he said had been made against him.

Florida Senator Marco Rubio criticized the ruling in strong terms, saying the court had "unjustly ruled to imprison former President Jair Bolsonaro" and vowing that the United States "will respond accordingly to this witch hunt." Rubio did not specify actions the U.S. might take.

Legal experts say Bolsonaro’s sentence can be appealed through Brazil’s judicial system, and his defense team has indicated it will pursue all available legal avenues. Lawyers are expected to argue that he should remain under house arrest while appeals proceed. Under Brazilian law, appeals can delay the start of a custodial sentence, but the precise legal path and timing will depend on motions filed and rulings by higher panels of the court.

The convictions stem from an investigation that intensified after the Jan. 8, 2023, attacks on Brazil’s congress, presidential palace and supreme court by supporters of Bolsonaro, who rejected the 2022 election result. Investigators have pointed to a broader effort to undermine the electoral process and to solicit the cooperation of the military and other institutions to overturn the vote.

Thursday’s decision was issued by a panel rather than the full court. Legal specialists said panels are routinely used in high-profile cases to conduct trials and hand down decisions, but that Bolsonaro’s team may seek review by the full Supreme Federal Court or other appeals courts. The convictions carry significant penalties and expose Bolsonaro to the prospect of spending much of the remainder of his life behind bars if appeals fail.

Bolsonaro’s political future and the broader implications for Brazil’s polarized politics were immediately thrust into the spotlight. Supporters have long rallied behind the former president, who governed from 2019 to 2022 on a right-wing platform. Critics contend the convictions are necessary to hold accountable efforts to subvert democratic institutions.

President Lula, who reclaimed the presidency in 2023, has said in the past that Brazil’s laws must be applied without exception. The administration declined immediate comment on the panel’s sentence, and the Supreme Federal Court issued only the text of the ruling and procedural details.

International reaction has varied. Some democratic governments and human rights observers have called for restraint and respect for due process, while Bolsonaro’s allies abroad have denounced the proceedings as politically motivated. The United States’ public remarks came from senior political figures, reflecting the international attention on Brazil’s legal handling of a former head of state accused of attempting to subvert an election.

If Bolsonaro’s appeals are exhausted and his sentence is upheld, Brazilian authorities will face a decision on where and how to enforce the prison term. In the meantime, the conviction and sentence deepen a bitter national debate about accountability, the rule of law and the resilience of Brazil’s democratic institutions.
