Sao Paulo:Brazil's Supreme Court delivered a ruling that could release almost 5,000 inmates still appealing their convictions, including former president Luiz Inácio Lula da Silva and other powerful figures jailed in a sprawling corruption investigation.
The court decided in a 6-5 vote late on Thursday that a person can be imprisoned only after all appeals to higher courts have been exhausted.
The decision appears to cover Da Silva, whose attorneys said that they will request his release on Friday. That move will initially depend on a judge based in the southern city of Curitiba, where the former president is jailed.
The ruling also covers others convicted in cases arising from the so-called Car Wash investigation, which has ensnared dozens of top politicians and business leaders in Latin America's largest nation. They will now be able to seek release.
Prosecutors from the Car Wash probe said in a statement the top court's decision "goes against the sentiment of repudiating impunity and the fight against corruption."
Supporters of Da Silva celebrated the ruling, holding up signs saying "Lula," the name by which the president who governed from 2003 to 2010 is universally known here.
The Supreme Court's debate began in mid-October and its result could throw Brazil's political landscape into uncertainty. Da Silva had been favoured to win the 2018 presidential election, but his conviction prohibited him from running. He remains a popular figure on the left, whose politicians and voters have ceaselessly called for his release.
The decision marks a sharp change for Brazil's top court, which in February 2016 accepted that defendants whose convictions are upheld may be jailed even if their other appeals are pending. Brazil's constitution states that no one can be considered guilty until due process is concluded.
"I'm not surprised, politicians rarely stay very long in jail," said Rivaldo Santos, a 43-year-old waiter in Sao Paulo. Da Silva "spent some time (in jail), which is a change, but not nearly as much as other people that committed crimes but didn't have judges and lawyers on their side."
Da Silva presided throughout rapid economic growth fueled by a commodities boom that expanded the country's middle class. His huge Bolsa Familia welfare program helped lift millions from poverty, and he left the office with an approval rating above 80%. The former union leader is widely referred to as a "political animal" whose impassioned oratory can just as easily elicit laughter or tears from those among his supporters.
Justice Gilmar Mendes, who voted for the release of inmates who have yet to conclude their appeals, said Da Silva's case "contaminated" debate on the case.
"That was not good at all for rational debate," Mendes, an open critic of the Car Wash probe.
