Jacob Doe v. The University of North Carolina System, et al.
The Court found that plaintiff counsel submitted filings containing multiple AI-driven errors: two cited cases that do not appear to exist (fabricated citations), quotations that do not exist in the purported source cases (hallucinated quotations), and mischaracterizations of cited holdings. Following an order to show cause (here), Counsel admitted these errors at a show-cause hearing, blamed misuse/failure to verify outputs of AI tools, and published an article as remediation. The Court criticized the article as minimizing the misconduct but concluded counsel acted in good faith and, given their record and remedial efforts, discharged the show-cause order without imposing sanctions.
