Limites subjetivos da coisa julgada em benefício de terceiro: a necessária interpretação do art. 506 do CPC de 2015

Abstract

The present dissertation aims to analyze the possibility of expanding the subjective limits of res judicata to benefit a third party who did not participate in the legal dispute in which the final decision was rendered. Through doctrinal and jurisprudential understanding, an exposition is constructed on how this hypothesis of expanding the subjective limit serves as a basis to promote the fundamental right to procedural effectiveness and legal certainty. On the other hand, the procedural aspects that guide this possibility are studied, namely the exercise of the adversarial process and the right to a full defense, ultimately concluding that it seems more appropriate to affirm the possibility of expanding the subjective limits of res judicata on an already decided matter to benefit third parties, provided that the principles of due process of law are respected.
