Problem

Colombian courts carry heavy caseloads. In January 2023 a Cartagena judge was deciding an appeal over whether a health insurer had to waive fees and pay transport for an autistic child from a poor family.

Approach

Judge Juan Manuel Padilla upheld the child's claim in a ruling dated 30 January 2023 and said he had used ChatGPT 3.5 to extend the ruling's reasoning, pasting its answers into the decision. He said he had reached the decision himself and used the tool afterwards. Reviewing the case, the Constitutional Court found in ruling T-323 of 2024 that due process had not been violated, but that the judge fell short on transparency and responsibility.

Takeaway

The Court did not ban generative AI in courts. It drew a line between drafting help and the non-delegable work of weighing facts and evidence and reasoning a decision, and asked the judiciary's governing council to issue guidelines.

The ruling reviews the January 2023 second-instance decision in which the Cartagena judge said he had used ChatGPT 3.5 after reaching his decision. It finds no due process violation, because the tool did not replace the judge's reasoning, but says transparency and responsibility standards were not fully met. It sets twelve criteria, including transparency, verification and human control, and orders the Consejo Superior de la Judicatura to issue guidelines within four months.
