Changes after the great world wars, especially the bad things caused by German's Third Reich caused an upheaval in the study and application of legal standards. The fear that Law could be used as a tool capable of inflicting such horrors fostered the establishment of Constitutional
Courts besides the development of the American judicial review of judicial construction of Law, that also spread during this time its ideals of democracy and the application of rules to the rest of the world. The model of the welfare and democratic state brings new rights,
especially of a fundamental basis and the institutes of political intervention in judges decision-making when established only by the Legislative and Executive Powers put into question the state of the triple division of power, created under the liberal state and it no

popular legitimacy through suffrage bringing the explanation of the subjectivist and procedural theories. In addition to this the ideas developed by Dworkin and Viehweg as possible solution to solving the problem of hard cases and legislative gaps. It is necessary to
think about the lasting or eternity of concepts of the Legalization of Judicial Activism in societies emerging from this new reality
