In the matter of Bayfoyle

SC New South Wales · Dec 23, 2025

Direct answer

What happened in this matter?

The court found that the solicitor relied on AI-generated, non-existent case law and failed to verify these authorities before filing. While the court characterized this as a serious matter, it concluded the AI misuse had little impact on the hearing's outcome and declined to initiate a professional disciplinary referral, leaving that action to the opposing party's discretion.

Why the court cared
Fabricated: Case Law | Submissions and outline relied on several non-existent case authorities likely generated by AI; an email falsely attributed one non-existent authority to a Court reference; court noted failure to verify.
Why it matters now
Verify every AI-surfaced authority against the primary source before filing; adverse costs follow unverified citations.

Why this matter is tracked

In the Supreme Court of New South Wales, the court addressed a costs application following the dismissal of winding-up proceedings. The solicitor for the plaintiffs, Mr. Smits, submitted an outline of arguments containing multiple non-existent case authorities, which the court identified as likely generated by artificial intelligence. The solicitor further falsely attributed one of these fabricated authorities to a court reference. The court found that the solicitor failed to verify the existence of the cited case law. While the court noted the seriousness of this conduct, it determined that the AI-generated citations had minimal impact on the overall proceedings and declined to refer the solicitor to the Legal Services Commissioner, noting that the defendant could pursue such a referral independently if desired.
