As a general goal, it aims to analyze the judicialization of lawsuits made by PSOL, in virtue of the unconstitutionality of bills going through the National Congress, under the light of the constitutional principle of the division of power. As specific goals, it brings forth the discussion regarding the comprehension of the judicialization of politics phenomenon in contemporary Brazil, as well as the analysis of the unconstitutionality lawsuits for bills that were judicialized by PSOL in the year of 2019. The applied methodology is the bibliographic review and document analysis (under the current law and using the data provided by PSOL, Federal Court of Justice and Parliament).
