Colisão de princípios no Sistema Constitucional Brasileiro: uma proposta de fórmula do peso brasileira

Abstract

This research intends to present rigorously the theory of the German jurist Robert Alexy, who contributed so much to one of the most delicate questions of contemporary constitutional law: the collision of legal principles. With the assumption that the Supremo Tribunal Federal could not use proportionality adequately to deal with the subject of collisions in Brazil, the research investigates the work of the theorist to expose the concepts and methods used to arrive at a reasonable resolution of legal cases involving fundamental rights principles on opposite sides. For that, what is understood by norm, normative statement, principles, rules, values, subjective rights, collective interests, legal argumentation and maximum of proportionality are exposed. At a later moment, with the assumption that brazilian jurists who had dialogues with Alexy's theory ignored a significant part of the work, which presents a reformulation of the maximum of proportionality to answer the criticism on decisionism, the research demonstrates the functioning of the weight formula and how its magnitudes are measured, such as the intensity of the intervention, the importance of satisfaction, the abstract weight, the safety of empirical assumptions and the safety of normative assumptions. The research also intends to propose an adaptation of Alexy's theory to the Brazilian Constitutional System, since the maximum of proportionality was developed for german law and does not consider the daily life of the brazilian courts. With the proposition of balancing between subjective and objective magnitudes in the Brazilian weight formula, the method reaches a level of rationality adequate for everyday application in brazilian courts
