Nevertheless, the Brazilian Constitution promulgated in 1988 gave a fresh role to these Courts, expanding the fields of their action, mainly after Supreme Court decisions, which has interpreted the Constitution and has conceded powers to them. This paper aims to investigate the new role of Courts of Audit, exposing the concerns about the expanded field of the public affairs control and proposing a new organized bureaucratic structure of the Brazilian Government.
