Attorney General Raquel Dodge ordered an investigation into the actions of appeals judge Rogerio Favreto, who was the weekend duty magistrate.
Dodge said there was evidence that when he acted professionally, he did so "motivated by personal feelings and interests," according to a statement from the attorney general's office.
Lula, still the favorite ahead of the October presidential election, has been serving a sentence of 12 years and one month in prison for corruption and money laundering for more than 3 months. He insists he is innocent.
The appeals judge on Sunday, July 8, ordered Lula freed, in violation of procedures and regulations, Dodge said.
