Latest Court Petitions
It was only on the previous day that the former president's lawyers asked the High Court to permit him to fulfill his full incarceration period under home confinement, with tracking devices.

Background on Conviction
He was convicted of orchestrating a scheme aimed at retaining his authority after he lost the presidential race to his left-wing rival, President Lula.
High Court judges said that he had knowledge of a plan which included plans to murder the current president and his VP candidate, his vice-presidential candidate, and to imprison and murder the presiding judge - the top judicial official who has been presiding over the former president's case.
The scheme was prevented because it failed to get the backing of the military leaders. Lula was sworn in without problem on 1 January 2023.
But a week later, on January 8th, many Bolsonaro supporters stormed and vandalised public facilities in the federal district, Brazil's capital.
The security forces stepped in and around approximately 1,500 persons were taken into custody.
The judges found that the protesters had been incited by him whose scheme, they said, was for the country's army to take action, restore order and bring him back to power.
At the moment, his attorneys called the 27 years and three months sentence unreasonably severe".
He was also prohibited from campaigning for office until 2060 - eight years after the end of his sentence.
The former president called the court case a "witch hunt and said it was aimed at blocking him participating in the 2026 presidential election.
