This research aligns with studies investigating the constitutional changes and contemporary constitutional thought. Taking as a starting point Günter Frankenberg’s theory of constitution, we propose an adaptation of the classic program of the theory of constitution of a complex normative grammar, able to understand other points of view, not only in the sphere of interpersonal relations, as in the transnational sphere. The research, descriptive and prospective, aimed to propose the rehabilitation of the conflict, defined from the concept of politics, written by Carl Schmitt in his famous work of 1932. The premise adopted is that the theory of the constitution is placed in a limited way to not see the continuity in the constitutional process to which it links and is intended to describe. Although most of the ideas in this research work have been originated in a different sociopolitical and legal environment, the exchange of ideas and their harmonization with the Brazilian context is undoubtedly of great importance for the development of constitutional thought in Brazil. The contemporary constitutionalism is now living the breakthrough of consensus: to deny the differences and aim a single ideal of good life is incompatible with the conflicts within society. The tense relationship between law, politics and the Constitution is overwhelmed by the demand for integration that comes form a plurality of societies and cultures. The objective of this study is to verify that an adequate contemporary setting of this relationship can go through the rehabilitation of a theory of conflict.
