Lawyers face sanctions for citing fake cases with AI, warns UK judge

LONDON (Reuters) -Lawyers who use artificial intelligence to cite non-existent cases can be held in contempt of court or even face criminal charges, London's High Court warned on Friday, in the latest example of generative AI leading lawyers astray. A senior judge lambasted lawyers in two cases who apparently used AI tools when preparing written arguments, which referred to fake case law, and called on regulators and industry leaders to ensure lawyers know their ethical obligations. "There are serious implications for the administration of justice and public confidence in the justice system if artificial intelligence is misused," Judge Victoria Sharp said in a written ruling.
