  • Oregon’s high court recently struck down parts of two cases where AI-generated citations and quotes were found to be fabricated.
  • This marks the first time the state’s Supreme Court has formally addressed the issue of false information from AI tools in legal filings.
  • Experts warn that lawyers and self-represented individuals are increasingly using AI products to create false citations, impacting over 1,000 cases nationwide.
  • In a notable case, lawyers representing MyPillow’s chief executive were fined $3,000 each by a federal court for submitting AI-generated mistakes.
  • In Oregon, a lawyer was fined $110,000 in a district court, the highest penalty recorded yet for using AI to fabricate legal arguments.
  • Chief Justice Meagan A. Flynn highlighted the burden these fabricated legal arguments impose on the court, diverting resources from other cases.
  • In one dismissed case, plaintiffs repeatedly submitted papers containing AI-generated falsehoods despite being asked to correct them.
  • Similarly, in another case, the respondents used unverified legal arguments, requiring a $500 fine and the opportunity to resubmit a corrected document.
