The court also struck a response to a petition in a separate case over AI-generated falsehoods. The cases are the first time the state’s highest court has addressed legal fabrications created by artificial intelligence.
Oregon’s high court has for the first time addressed legal cases impacted by AI-generated fabricated citations, reflecting a growing national concern. Experts estimate over 1,000 cases nationwide contain inaccuracies due to AI tools. Notably, lawyers for MyPillow’s CEO faced $3,000 fines for AI-induced errors, and an Oregon lawyer received a record $110,000 penalty, highlighting the severity and prevalence of this issue in the U.S. legal system.
Chief Justice Meagan A. Flynn issued a statement on the rulings, acknowledging the perceived allure of AI products as legal research shortcuts. However, she underscored the significant burden these tools impose when they generate fabricated arguments. This forces the court to expend considerable time and effort verifying information, which in turn diverts resources and attention from other legitimate cases awaiting judicial review.
In one of the two cases addressed, the Oregon Supreme Court outright dismissed a petition for a writ of mandamus. This decision came after the plaintiffs submitted supporting documents that included non-existent legal cases and fabricated quotes, which were generated using 'LegalAI.' Despite being given an opportunity to correct the errors, the plaintiffs’ resubmitted paperwork still contained AI-generated falsehoods, leading to the dismissal.
In a separate but related incident, the high court imposed a $500 fine on a respondent. This penalty was issued because the individual filed a document containing legal arguments that could not be substantiated or verified against existing Oregon case law. Unlike the first case, the court offered the respondent a chance to resubmit the corrected document, indicating a potential pathway for rectification despite the initial AI-induced error.
Ankur Doshi, General Counsel of the Oregon State Bar, expressed significant concerns on OPB’s “Think Out Loud,” noting that AI fabrications are found in submissions from both licensed lawyers and self-represented individuals. He highlighted that these fabricated citations create substantial additional work and resource drain for both the court staff and opposing counsel, often leading to increased attorneys' fees for the adverse party, making the issue particularly aggravating for all involved.
