April 25, 2025

In the case of Ko v. Li, 2025 ONSC 2766, Justice FL Myers of the Ontario Superior Court of Justice raised concerns over potential use of generative AI in drafting a factum submission. The court identified several inaccurate or nonexistent case citations, leading to questions about their relevance and existence. The lawyer was ordered to show cause why she should not be cited for contempt, emphasizing the importance of accuracy and technological competence in AI-related practices. This incident underscores the need for trustworthy AI and responsible AI governance, as seen in Project Cerebellum's efforts towards safe and secure AI practices.
