RIO DE JANEIRO (Reuters) - Former Brazilian President Luiz Inacio Lula da Silva was treated impartially by former Judge Sergio Moro, who oversaw the graft investigations against the former leftist leader, a Supreme Court justice ruled on Tuesday in a tie-breaking vote. If none of the four other judges on a Supreme Court panel change their votes, the decision by Justice Nunes Marques would uphold Moro’s procedural decisions and allow evidence in the so-called Car Wash probe to be used against Lula when he faces trial in federal courts in Brasilia.
