Controversy surrounded Genro's decision to grant refugee status to Battisti. Many law specialists have said that the decision was illegal. The Brazilian Supreme Court began trying the case in September 2009. By 5 to 4 (simple majority), the court ruled Genro's decision null and void on 18 November. However, the court also decided by 5 to 4 that the Brazilian constitution gives the president personal powers to deny the extradition if he chose, effectively putting the decision in the hands of Brazilian President Luiz Inácio Lula da Silva.
