The decision published yesterday names Silva and five others as co-conspirators in an alleged attempt to buy the silence of a former Petrobras director implicated in the scandal. A date for the trial has not yet been set.
The obstruction-of-justice accusation against Silva comes from a plea bargain testimony by former Sen. Delcidio do Amaral, who was stripped of his seat by his peers and will also stand trial.
Silva, who is universally known in Brazil as Lula, denied any wrongdoing. "It is up to the prosecutors and federal police to prove what they say," he said.
His supporters say the latest decision by federal judge Ricardo Leite is retaliation for lodging the petition with the UN committee.
