Descolamento institucional: o Ministério Público Federal e a Operação Lava Jato

This article aims at enlightening the constitution of the actor Operation Car Wash (OLJ), investigating to what extent it is possible to think of an actor which detaches itself from its original institution, the Federal Prosecutor Service (MPF), starting to appear as a relevant political agent. For such, we start from the meanings expressed in the first criminal complaint of the operation against former president Lula and from quantitative data collected from the 58 criminal complaints of this operation, from the core of Curitiba, carried out between 2014 and 2016. Initially, we infer the constitution of the actor of the enunciation in the complaint. The elements included in the text show the construction of two different actors, even if interconnected. We conclude, through semiotic analysis, that this separation occurs through a screening, in which in the MPF there is a euphorization of the universe values – composing democratic values –, while, in the OLJ, there is a euphorization of the absolute values – composing aristocratic values, characterized by a hyperbolic and anti-political discourse.
