Geha Enterprises Pty Ltd v Deuteronomy 28 Investments Pty Ltd and Registrar General of the ACT
ACT SC · Apr 21, 2026
What happened in this matter?
The ACT Supreme Court refused to grant leave for a corporate director to represent his company after he submitted written arguments containing two fabricated legal authorities generated by AI. The court dismissed the application and ordered the defendant to pay the plaintiff's costs.
- Why the court cared
- The court reasoned that the applicant's use of generative AI to produce non-existent legal authorities demonstrated a lack of professional rigor, undermining his claim that his legal qualifications justified an exception to the rule requiring corporate legal representation.
- Why it matters now
- This case illustrates the risks of using generative AI for legal research without verification. The court explicitly cited the submission of fabricated authorities as a factor in denying the applicant's request to represent his corporation, highlighting the impact of AI-generated hallucinations on judicial credibility assessments.
Why this matter is tracked
In an interlocutory application before the Supreme Court of the Australian Capital Territory, the court considered whether to grant leave for a non-lawyer director to represent a corporation. The applicant relied on written submissions containing three legal authorities, two of which were found to be non-existent and generated by AI. The court noted that the applicant conceded the use of generative AI. Finding that the reliance on fabricated authorities weighed against the applicant's credibility and that the case involved significant complexity, the court refused the application for leave to represent the corporation. The court dismissed the interlocutory application and ordered the first defendant to pay the plaintiff's costs.
