The defence team for Brazil's suspended president Dilma Rousseff said that it will file four petitions in the Supreme Federal Court on the impeachment process against her.Defence team head Jose Eduardo Cardozo said at a press conference on Friday that the petitions would be filed before Ricardo Lewandowski, Chief Justice of the Supreme Federal Court, Xinhua news agency reported.The petitions mainly focus on the unfair treatment Rousseff and her supporters received in the impeachment process, including insufficient time for her defense team to address all the filings against her and appointing a biased Senator as the rapporteur who, supposedly, should be impartial.According to Cardozo, over 80 separate filings had been lobbied by the Senate against Rousseff but her defence team was only given 10 minutes to address them all."I am not good at math but I think we would have around 7 seconds to address each filing," said Cardozo, who was the country's attorney general during Rousseff's time in office.Another important petition, according to Cardozo, is asking the Supreme Federal Court to allow the inclusion of new evidence, including recently leaked recordings made by a former Petrobras executive.In the recordings, several senators who have been pushing for Rousseff's impeachment seemed to say that doing so is the best way to shut down a high-profile corruption investigation involving members of Brazil's political class.
