Expert Systems: The Case of Justo in the Digital Transformation of the Peruvian Justice System

The study examines the impact of “Justo” AI on the digital transformation of the Peruvian justice system, comparing it to other expert systems. Accelerated by COVID-19 and aligned with the United Nations Sustainable Development Goals, the implementation of AI in justice has become crucial. The methodology involved a systematic review of the literature on expert justice systems and an analysis of the results of JUSTO 2022 using data from “El Peruano” and the Superior Court of Lima Norte. “Justo” correctly identified 71.68% of death orders, completing in 9 hours what would take a human 3 years. Despite being less advanced than other systems, “Justo” marks a significant step in Peruvian judicial automation by balancing efficiency and human oversight. To enhance its impact, “Justo” must expand its capabilities, develop an ethical framework, and integrate more advanced technologies appropriate to the Peruvian context, which will position it as a more robust system.
