The High Court of England and Wales warned lawyers on Friday that they could face criminal prosecution for presenting false material generated by artificial intelligence, after a series of cases cited made-up quotes and rulings that did not exist. The ruling by Victoria Sharp, president of the King’s Bench Division of the High Court, and a second judge, Jeremy Johnson, detailed two recent cases in which fake material was used in written legal arguments that were presented in court. In one case, a claimant and his lawyer admitted that A.I. tools had generated “inaccurate and fictitious” material in a lawsuit against two banks that was dismissed last month. In the other case, which ended in April, a lawyer for a man suing his local council said she could not explain where a series of nonexistent cases in the arguments had come from.
