Leung v Omnia Inclusive Employment Solutions Ltd
Federal Court · May 15, 2026
What happened in this matter?
The Federal Court of Australia declined to impose costs on a pro se litigant who used ChatGPT to generate court submissions containing incorrect citations and cross-references. The Court held that while the risks of generative AI are significant, the respondent failed to demonstrate that the specific costs incurred were solely attributable to the AI-generated content or that the filing constituted an unreasonable act under the Fair Work Act.
- Why the court cared
- The Court reasoned that while the use of generative AI by a litigant in person to produce submissions with incorrect references is problematic, it does not automatically constitute an 'unreasonable act' under s 570(2)(b) of the Fair Work Act. The Court found the respondent failed to isolate specific costs 'thrown away' due to the AI content, noting overlap with subsequent filings.
- Why it matters now
- This case highlights judicial reluctance to penalize pro se litigants for AI-generated errors absent clear evidence of unreasonable conduct or quantifiable wasted costs, while affirming that the risks of generative AI are well-understood by the court.
Why this matter is tracked
In an appeal before the Federal Court of Australia, the appellant, a litigant in person, filed submissions in September 2025 generated using ChatGPT. The respondent sought costs, arguing the submissions contained incorrect cross-references to evidence and cases, constituting an unreasonable act under s 570(2)(b) of the Fair Work Act 2009 (Cth). The Court acknowledged the inherent risks of using generative AI but noted that the specific extent of costs incurred due to the AI-generated content was not clearly separable from other submissions. Consequently, the Court declined to order costs against the appellant, finding the filing did not meet the threshold for an unreasonable act warranting a costs order in this context.
This case highlights judicial reluctance to penalize pro se litigants for AI-generated errors absent clear evidence of unreasonable conduct or quantifiable wasted costs, while affirming that the risks of generative AI are well-understood by the court.
