Zanin was approved by the Senate on June 21 and officially appointed minister by the president on July 5.
The jurist, who will occupy Lewandowski’s seat, who retired in April, acted in Lula’s defense in proceedings of the dismantled judicial operation Lava Jato, when he gained national and international notoriety.
His performance resulted in the annulment of the convictions against the former trade unionist by the Federal Supreme Court.
During the analysis in the Senate Constitution and Justice Committee, Zanin affirmed that he would act with impartiality and that he would not be subordinated to the former labor leader, despite the close relationship with the head of state.
“I am honored to talk to many leaders, and senators individually. I was able to listen, learn and be sure that democratic positions are above any other interest”, said the 47-year-old lawyer in the senatorial session.
