Incident 10992 Report
Factum in Ko v. Li Allegedly Contains AI-Generated Case Law Citations

2025-04-25

In Ko v. Li, 2025 ONSC 2766, the Ontario Superior Court of Justice identified multiple inaccurate or nonexistent case citations in a factum submitted by counsel for the applicant. Justice FL Myers questioned whether generative AI was used in drafting the document, noting the cited cases were either irrelevant, misrepresented, or did not exist. The court ordered the lawyer to show cause why she should not be cited for contempt, citing duties of accuracy and technological competence.

Incident 11381 Report
Rodrigues Blignaut Attorneys Reportedly Relied on Unverified ChatGPT Case Law in Johannesburg Body Corporate Defamation Matter

2023-03-01

In a defamation case at the Johannesburg Regional Court, Rodrigues Blignaut Attorneys, representing plaintiff Michelle Parker, reportedly relied on purportedly non-existent legal judgments generated by ChatGPT to help argue their case. Magistrate Arvin Chaitram reportedly found the case names and citations were fictitious, causing a two-month delay. The court issued a punitive costs order and rebuked the plaintiff's legal team for uncritically accepting AI-generated research.
