Citation errors and hallucinated case turn up in Boies Schiller brief in 'artificial-intelligence debacle'

"Original Jurisdiction, a Substack publication by Above the Law founder David Lat, covered the mistake. "There's no denying that this is ... suboptimal," Lat wrote. "Involving a Vault 100 and Am Law 200 law firm that's a litigation powerhouse, it's arguably BigLaw's biggest artificial-intelligence debacle to date." Other BigLaw firms snagged by AI mistakes include Butler Snow, K&L Gates and Latham & Watkins (its error involved a footnote)."

"The Church of Scientology pointed out the mistakes in a brief. "Multiple sections of plaintiffs' brief are filled with erroneous citations that mischaracterize holdings and refer to cases on unrelated areas of law," the Church of Scientology lawyers wrote. "Some cases are mistitled such that it is difficult to determine what cases plaintiffs are intending to cite in the first place. And one case plaintiffs cite is completel"

John Kucera, a partner at Boies Schiller Flexner, said artificial intelligence was used in preparing a plaintiffs' brief and accepted responsibility for material citation errors, and he sought to file a corrected brief. Kucera wrote that he was embarrassed and regretted the errors. The Church of Scientology, in an appeal seeking dismissal, flagged numerous erroneous citations that mischaracterized holdings, cited unrelated law, and included mistitled cases. Coverage by Original Jurisdiction and commentary noted the mistake as a significant AI-related debacle for BigLaw, citing other firms that have faced AI-generated errors.
