Wang v Moutidis
County Court of Victoria · Aug 18, 2025
What happened in this matter?

- Why the court cared

- Why it matters now
- When opposing a pro-se litigant's AI-fabricated quotes, demand the primary exhibit to expose the fabrication fast.
Why this matter is tracked
In a domestic building contract dispute, the self-represented defendant, Mr. Moutidis, submitted written closing arguments containing significant AI-generated content. The presiding judge, Her Honour Judge Kirton, noted that the submission included fabricated case law and misrepresented expert reports, with the Gen AI output contradicting the actual expert testimony. The court explicitly disregarded these written submissions, relying instead on oral evidence and contemporaneous documentation. The judge highlighted the unreliability of the AI-generated material, noting that it cited non-existent cases and misstated legal principles, which necessitated a formal judicial record of the AI's failure to provide accurate or relevant information.
