MELBOURNE, Australia — A prominent lawyer has publicly apologized to a judge after submitting court documents in a murder trial that featured fabricated quotes and non-existent case rulings generated by artificial intelligence. This incident, arising in the Supreme Court of Victoria, highlights the ongoing challenges the legal system faces with the increasing reliance on AI technology.
Rishi Nathwani, a distinguished legal figure holding the title of King’s Counsel, accepted “full responsibility” for the inaccuracies presented in his filings for a case involving a teenager accused of murder. Nathwani expressed profound regret and embarrassment before Justice James Elliott during a court hearing.
The errors caused a delay of 24 hours in the proceedings, which Justice Elliott had anticipated concluding promptly. On Thursday, the court determined that the minor defendant was not guilty of murder due to mental impairment. Elliott remarked that the unfolding of these events was “unsatisfactory” and emphasized that the integrity of legal submissions is essential for the justice system to function effectively.
Among the inaccuracies were made-up quotes purportedly from discussions in the state legislature and fictitious citations that were wrongly attributed to the Supreme Court. The falsehoods were unearthed by the judge’s associates when they could not verify the cited cases and requested further documentation from the defense.
In their subsequent admission, the defense acknowledged that the references did not exist and confirmed that the submissions were based on “fictitious quotes.” They also indicated that they initially verified the accuracy of the first set of citations, mistakenly assuming that the rest would also be correct.
The flawed submissions were also distributed to the prosecution, represented by Daniel Porceddu, who failed to verify their contents. Justice Elliott took note of the Supreme Court’s guidelines issued last year regarding the use of artificial intelligence, asserting that AI-generated materials must be independently verified before submission.
The specific AI system employed by the defense team for this case has not been disclosed. This incident in Australia is not isolated. In a similar situation in the United States earlier this year, a judge sanctioned two attorneys and their firm after they submitted fictitious legal research generated by ChatGPT during an aviation injury claim. The judge recognized their responsibility in the matter but ultimately avoided imposing harsher penalties after they took corrective actions.
This suggests a growing concern within legal circles about the use of artificial intelligence in legal practices. In another instance later this year, similar misleading court rulings were referenced in legal documents submitted by lawyers for Michael Cohen, a former attorney for Donald Trump. Cohen took responsibility for the errors, claiming he was unaware of the limitations of the AI tool that produced them.
As the legal community navigates the integration of artificial intelligence, incidents such as these underscore the critical need for rigorous verification processes to maintain the credibility of the justice system.
