Description: The Penal Chamber of Esquel, Argentina, reportedly annulled a June 2025 robbery conviction after determining that Judge Carlos Rogelio Richeri had allegedly used ChatGPT to draft part of the ruling without disclosure or human oversight. A copied phrase purportedly exposed AI authorship, prompting findings of due-process violations and data-handling concerns. The case was reassigned, and the Chubut Superior Court opened an ethics investigation.
Editor Notes: A note on the harmed party: Although the annulment ultimately favored the defendant, he is listed as a harmed party because the alleged improper use of AI in the original ruling constituted a violation of due process at the time the judgment was issued. A note on the timeline: Date reflects the original ruling (06/04/2025) in which generative AI content was allegedly used. The annulment occurred in October 2025 following appellate review. The incident ID was added to the AIID on 11/08/2025.
