The Tribunal Superior de Bogotá quashed a criminal conviction and remanded the case for a new trial because the trial judge used AI to generate legal reasoning that included fabricated case law and non-existent doctrinal sources.

Why this matter is tracked
The Tribunal Superior de Bogotá quashed a first-instance criminal conviction after finding the trial judge relied on AI-generated content containing multiple hallucinations. The appellate court identified that the trial judge cited non-existent Supreme Court decisions, a fabricated doctrinal work, and misrepresented Constitutional Court jurisprudence to support the conviction. The appellate court concluded that the trial judge failed to exercise necessary human oversight, effectively delegating judicial reasoning to the AI tool. This failure to verify the accuracy of the decision's legal basis violated the defendant's right to due process and the duty of judicial motivation. Consequently, the court declared the judgment null and void, remanded the case for a new trial, and referred the matter to the disciplinary commission for investigation.
