The chief justice of Brazil’s Supreme Court on Wednesday knocked down a decision by a fellow judge that would have freed imprisoned former president Luiz Inacio Lula da Silva.
Chief Justice Jose Antonio Dias Toffoli ruled that the full court would have to take up the case after it returns from holiday recess.
Earlier on Wednesday, Justice Marco Aurelio Mello approved an appeal that would have freed Lula.
Lula was jailed in April after being sentenced to more than 12 years in prison, and faces six other trials for alleged corruption. He has maintained his innocence.
Justice Marco Aurelio Mello issued the decision, which suspends the enforcement of the same court's earlier ruling that allows for convicts to be jailed after their sentence is upheld on first appeal, as was the case with Lula.
Mello's decision must next be considered by the full panel of the Supreme Court, which is divided on the issue of whether to allow those convicted to remain free until their case fully winds through Brazil's complex and backlogged legal system.
Gleisi Hoffmann, who leads the leftist Workers Party that Lula founded, said via Twitter that the party had already filed legal requests before the top court to request that Lula be freed.
The office of Brazil's prosecutor general said it was studying Mello's decision and weighing its options. Prosecutors strongly oppose any backtracking on the ability of lower courts to order convicts to prison after their conviction is upheld on a first appeal.
Brazil's incoming justice minister Sergio Moro, the lower court judge who condemned Lula and who oversaw the trials resulting from the country's sprawling "Car Wash" corruption investigations, has said he will introduce legislation to pass a law mandating that those convicted on appeal be sent to jail.
Lula was president from 2003 to 2010. He rode a commodities boom and used social policies that helped lift millions from poverty.
He easily led early polls for this past October's presidential election and registered to run.
But he was blocked from doing so by a law that strips those convicted of crimes upheld on appeal from running for office, a decision that would not be impacted by his possibly being freed.
