Loishirl W. Hall, an attorney at a large financial institution, Deutsche Bank Nat'l Trust Co., submitted a brief to the D.C. Court of Appeals that included citations to cases that didn't exist. When questioned by the court, Hall admitted that four of these citations were "not legitimate legal authority" and likely generated by artificial intelligence (AI) "hallucinations." The court was unable to locate or confirm these cases as legitimate references. Hall's response, filed on June 23rd, acknowledged the error and assured the court that she would personally verify all citations in future briefs, rather than relying on AI tools without confirmation. This incident has raised concerns about the use of AI in legal research and the potential consequences for attorneys, their clients, and the courts. The case is part of a growing discussion about accountability in law firms when using AI to draft documents and briefs.
