Hallucination

A Pennsylvania federal court suspended an attorney six months for AI-hallucinated citations

In June 2026, U.S. District Chief Judge Matthew Brann of the Middle District of Pennsylvania sanctioned attorney Nicholas W. Mattiacci Sr. for filing briefs with AI-generated hallucinated citations, ordering a $1,500 penalty and suspending him from practice in the district for six months beginning June 22. The judge rejected the attorney's attempt to blame research tools and label the errors inadvertent, and noted it was not his first disregard for the court's rules.
