Complexidade do sistema da lei de arbitragem brasileira N.º 9.307, de 23 de setembro de 1996: Sistema estatal nem sempre se mostra aberto ou acessível <i>Vale a pena litigar quando se pode optar pela arbitragem?</i>

This study analyzes Law No. 9,307/1996, which established arbitration in Brazil, highlighting its relevance in the national and international legal and economic contexts. The law emerges as a response to the deficiencies of traditional judicial proceedings, characterized by excessive delays, high costs, inequality between the parties, and low effectiveness in enforcing decisions. Arbitration is presented as an alternative, offering greater speed, flexibility, and autonomy to the parties. However, tensions remain between the autonomy of the litigants’ will and the need for judicial intervention, which gives the law an unstable character. This paper discusses these contradictions based on theoretical foundations and reflections developed during a doctoral course in Legal and Social Sciences at the Universidad del Museo Social Argentino.
