The purpose of this study is to analyze the models of technological application of judicial precedents by the STF, which intend to automate the admissibility determination, and to determine whether such technology can be used without violating constitutional principles, particularly due process of law. The core of the study consists of the artificial intelligence tools utilized by the Judiciary to assist the judicial activity in dealing with the phenomenon of hyperjudicialization. Consequently, we present the precedent system of the Civil Procedure Code of 2015, which aims to ensure and apply the principles of isonomy and legal certainty, as well as reduce the problem of repetitive actions. In addition, the employed artificial intelligence systems and the most pertinent problems they present, such as biased data sets, algorithmic opacity, and racial and social discrimination, were examined. The Federal Supreme Court s use of the Victor System, which aims to automate the appeals admissibility determination, was also discussed. Lastly, an effort was made to evaluate how technologies can contribute to a more efficient appeals processing, particularly with regard to the admissibility determination.
