Collective suits and homogeneous individual rights in Brazil: a critical view about efficacy. In this article, the authors initially offer an overview of collective suits in Brazil and describe the evolution of the legislation related to this subject. They examine the controversies born in the context of the relationships between the citizens and the Government; and between mass suppliers and consumers in Brazil. They consider this kind of exam useful not only to understand the Brazilian reality, but also to compare it to other systems. Therefore, the article analyzes the different ways to file a suit grounded on homogeneous individual rights, including issues like standing to sue and res judicata. Thus, the article questions the reasons why collective suits are not, in the authors’ opinion, effective, by examining the difficulties to manage those kinds of controversies prior to the suit, especially considering the role expected from and performed by the public regulatory agencies. The authors also criticize the maintenance of the res judicata erga omnes in utilibus rule and propose some alternatives to improve the Brazilian legal system.
