A judge has sanctioned two attorneys involved in a shipping contract dispute for submitting a legal brief containing a fabricated case citation generated by artificial intelligence. The court emphasized that lawyers must carefully verify their references and avoid relying on AI hallucinations in legal documents. The issue has drawn broader attention as a law firm defending conditions at a Baltimore jail also faces sanctions for AI-generated filings. The High Court is reportedly considering contempt of court proceedings against lawyers who have submitted briefs with false citations. One attorney admitted to using ChatGPT to produce nonexistent case references despite the firm explicitly prohibiting the use of large language models in legal work.
