In addition to that, the new Constitution created the Federal Court of Accounts (Tribunal de Contas da UniĆ£o), which is also autonomous in its functions.Prosecutors have the last word on whether criminal charges are filed, except in those rare cases in which Brazilian law permits civil prosecution.Although the law allows prosecutors to conduct criminal investigations, they only do so in major cases, usually where there has been wrongdoing involving the police or public officials.Until the Constitution of 1988, Brazil adopted a worldwide-common system: the legal representation of the Union (the federation), the states, the Federal District, and the municipalities, was attributed to the Public Prosecutor's Office, which had a main role as a public ministry of attorneyship and also would act in defense of weaker classes, such as poorer, elder and native people.Under the will to develop the protection to civil rights and improve the democratic control of the Government, however, the Constitution created a new system, advancing from the old theory of tripartition, bringing the Essential Offices to the Justice (articles 127 to 135).
