This study deals with the stabilization of the antecedent preliminary injunction as a way of guaranteeing the satisfaction of the plaintiff in the 2015 Code of Civil Procedure. The general objective is to analyze the theoretical precepts of the 2015 Code of Civil Procedure, in order to verify whether there is stabilization of the preliminary interim relief when the defendant does not appeal the decision that guaranteed the satisfaction of the plaintiff. Thus, the research is justified because injunctive relief, in the procedural sphere, is of fundamental importance, as it is one of the most important techniques for preventing the time needed for the process to last from causing damage to the rightful party. The first chapter discusses the constitutionalization of the process and the influence of the constitutional principles of civil procedure in the context of interim relief, as well as comparisons and changes to the 1973 and 2015 CPCs. In the second chapter, we analyzed the birth of the stabilization of preliminary injunctions in the 2015 CPC, and we also analyzed the attempt to summarize the Brazilian process through the stabilization of preliminary injunctions.
