Why this matter is tracked
In an employment discrimination claim before the UK Employment Tribunal, the pro se claimant submitted written arguments containing multiple case law citations generated via ChatGPT. During the proceedings, the claimant was unable to provide the full citations, references, or copies of these authorities. Counsel for the respondent and the Tribunal attempted to locate the cited cases but were unsuccessful. The Tribunal informed the claimant that because the authorities could not be verified or produced, they would not be relied upon in the court's decision-making process. The Tribunal ultimately dismissed the claimant's complaints of harassment and direct race discrimination, finding them out of time or not well-founded, without imposing sanctions for the use of the AI-generated citations.
