For this, we discussed the proposal of the thesis of abstractivization that supports the alteration of the traditional role of the Federal Senate, in art. 52, X, of the Constitution of the Federative Republic of Brazil (CRFB) of 1988, in order to assign general efficacy to the decisions, in the diffuse control, of the Supreme, and to have the function of divulging these decisions. The arguments were favorable and contrary to the thesis, and a parallel was drawn between Complaint 4335/AC and Direct Actions of Unconstitutionality (ADIs) 3406 and 3470, whose judgments impacted the jurisprudence of the Supreme Court on the subject of the study. Also the normative instruments that materialized the abstractivization in the legislative scope were verified. The result was that there is a tendency to approximate the effects of the declaration of unconstitutionalities between diffuse and abstract models, but it can not be said that the Supreme adopted this position. To do so, we adopted the methodology of research classified as deductive, the methods of comparative and hermeneutic procedure, as well as bibliographic, legislative and jurisprudential sources.Acesso AbertoControle de constitucionalidadeControle difusoTeoria da abstrativizaçãoJurisprudência defensivaControl of constitutionalityDiffuse controlTheory of abstractivizationDefensive judgmentTrabalho de Conclusão de CursoCiências Sociais AplicadasDireito
