Abstract

This article examines the impact of ChatGPT on judicial reasoning, focusing on a recent Colombian case where the judge utilized ChatGPT in the decision-making process. The case, decided in January 2023, provides a unique “pilot case study” on the subject, as the judge, in the decision, openly referenced the questions he posed to ChatGPT and the responses of the system. The article explores the case’s implications, the initial reactions to it, and its meaning and implications within the evolving Colombian legal landscape regarding the integration of technologies into judicial proceedings.
