Lawyers in England and Wales have been warned they could face 'severe sanctions' including potential criminal prosecution if they present false material generated by AI in court.
The ruling, by one of Britain's most senior judges, comes on the back of a string of cases in which which artificially intelligence software has produced fictitious legal cases and completely invented quotes.
The first case saw AI fabricate 'inaccurate and fictitious' material in a lawsuit brought against two banks, The New York Times reported.
Meanwhile, the second involved a lawyer for a man suing his local council who was unable to explain the origin of the nonexistent precedents in his legal argument.
While large language models (LLMs) like OpenAI's ChatGPT and Google's Gemini are capable of producing long accurate-sounding texts, they are technically only focused on producing a 'statistically plausible' reply.
