120 court cases have been caught with AI hallucinations, according to new database

Lawyers representing Anthropic recently got busted for using a false attribution generated by Claude in an expert testimony. But that's one of more than 20 court cases containing AI hallucinations in the past month alone, according to a new database created by French lawyer and data scientist Damien Charlotin. And those were just the ones that were caught in the act. In 2024, which was the first full year of tracking cases, Charlotin found 36 instances. That jumped up to 48 in 2025, and the year is only half way over.
