(Re)estabilização de expectativas normativas: observações sobre o precedente judicial à luz da teoria dos sistemas de Niklas Luhmann

Abstract

As a reaction to the hyper complexity that gripped acentric (or rather, polycentric) (post) modern society, the words of the legislator began to have character increasingly vague and imprecise, giving leeway to the judge in carrying out the law. These legislative techniques represent true pores/openings of the legal system in the search for greater dynamism and adaptability to social reality. Transfer the dogma of strict tight legal security codes, to the idea of "justice" built in the process context. While important, this opening may cause "side effect" of producing disparate decisions, raising the possibility that similar cases have different treatment, generating unpredictability, mistrust and especially violation of the principle of equality. Moreover, with the internalization of social contingencies at a high level, the legal system becomes potentially more complex and is having difficulties in their ability to complexity reduction, consistent generalization of normative expectations and, consequently, differentiated production of communication (legal). In the light of the theory of Niklas Luhmann, we seek to demonstrate the importance of judicial precedents in the Brazilian legal system, which would appear as able to promote (re) stabilization of normative expectations symbolically generalized media, restoring confidence and the legal system unit, representing at the same time, stability and dynamics, legal consistency and social adequacy.
