Chen v. Goodmore Investments & Tawa
Supreme Court · May 1, 2026
What happened in this matter?
The Supreme Court of New Zealand dismissed the applicant's motions and identified that she had submitted fabricated and mischaracterized case law, likely generated by AI. While the court warned that such conduct could warrant sanctions for contempt or obstruction of justice, it did not impose additional penalties beyond standard costs.
- Why the court cared
- The Court reasoned that the applicant's reliance on non-existent or mischaracterized authorities undermined the administration of justice. It noted that while such misuse could constitute contempt or obstruction of justice, it opted not to impose specific sanctions beyond costs given the overall circumstances of the case.
- Why it matters now
- This case illustrates the judicial response to AI-generated hallucinations in pro se filings within a high-court setting. It highlights the court's expectation for rigorous verification of authorities and the potential for severe consequences, including contempt findings, for failing to ensure the accuracy of cited legal sources.
Why this matter is tracked
In a Supreme Court of New Zealand judgment, the court dismissed applications for leave to appeal filed by a pro se litigant, Ms. Chen. The court identified that several legal authorities cited by the applicant in her submissions were either irrelevant, mischaracterized, or entirely fabricated, appearing to be the result of generative AI hallucinations. Specifically, the court noted the citation of non-existent cases such as 'Peterson v Forbes' and 'Vélez v Ticketmaster NZ Limited,' and the misrepresentation of 'Dorchester Finance Ltd v Deloitte.' The court emphasized that the misuse of AI in legal proceedings threatens the administration of justice and warned that such conduct may constitute contempt of court or obstruction of justice, though it declined to impose specific sanctions beyond costs in this instance.
