UK judge warns of risk to justice after lawyers cited fake AI-generated cases in court
- The High Court heard two cases involving lawyers who used generative AI to produce legal arguments or witness statements on 7 June 2025.
- These cases arose because lawyers cited false authorities, some produced by AI, and the court found a failure to verify the accuracy of such material.
- The court decided not to start contempt proceedings, noting one lawyer was a junior barrister and another did not deliberately present false material.
- Dame Sharp highlighted a serious breach in fulfilling the essential duty to verify the accuracy of materials submitted to the court, cautioning that neglecting this responsibility could lead to harsh penalties.
- The judgment called for urgent regulatory action and sent copies to the Bar Council and Inns of Court to consider further steps on AI use in law.
