The Prosecution Office of Accounts (MPC) is a centennial institution, mandated under article 130 of the Brazilian Constitution. Its origins date back more than 120 years to Decree 1166 of October 17, 1892. Ever since, this specialized prosecution office has been a staple in the development of the State, as its own branch of the Brazilian Prosecution Service.  

At the core of the external control of Public Administration, the relevant institutional functions of the Prosecution Service (as embodied in the Brazilian Constitution of 1988 and governing laws) unquestionably conceive the Prosecution Office as a permanent institution, essential to the function of government oversight. In São Paulo State, the Prosecution Office of Accounts was established by Complementary State Law no. 1,110 on May 14, 2010, later amended by Complementary State Law no. 1,190/12.

The first civil service examination consisted of four separate phases: objective test, discursive test, oral test, and evaluation of titles. The presence of the Hon. Renato Martins Costa, then Vice-President of the São Paulo State Court of Accounts (TCE/SP), along with Directors Edgard Camargo Rodrigues and Antonio Roque Citadini, was a determining factor in emphasizing the equanimity of arguments during the oral phase.

With the participation of the State Prosecutor's Office and the Brazilian Bar Association, that civil service examination admitted nine attorneys, who were appointed by the São Paulo state governor and took office on March 21, 2012. 

Ever since, the Prosecution Office of Accounts has acted with full functional autonomy and independence in the external control of Government, exercising the role of guardian of the law to defend the legal system on behalf of the society of São Paulo State.
