Ngaruiya v. Gill
CA Arizona (1d) · Jun 16, 2026
What happened in this matter?
The court identified fabricated and inaccurate citations in a pro se brief, attributing them to the misuse of generative AI. Although the court affirmed the dismissal of the appeal and explicitly warned that such conduct is sanctionable, it declined to impose a formal sanction in this specific instance because the appellee did not file a response.
- Why the court cared
- The court reasoned that while the appellant's failure to cite the record and inclusion of fabricated citations justified dismissal, it exercised discretion to reach the merits. It further reasoned that it would not treat AI-generated falsehoods more leniently than human-generated ones, but declined to impose sanctions under ARCAP 25 because the appellee did not respond to the brief.
- Why it matters now
- This case illustrates judicial scrutiny of AI-generated content in pro se filings. It confirms that courts view fabricated citations as a serious breach of duty and explicitly reject the notion that AI-assisted fabrication warrants leniency, even if a formal sanction is not ultimately applied.
Why this matter is tracked
In an appeal from a foreclosure-related dismissal, the Arizona Court of Appeals identified that the pro se appellant's opening brief contained numerous fabricated and materially inaccurate legal citations. The court noted these errors were consistent with the misuse of generative artificial intelligence. While the court explicitly stated that such conduct warrants sanctions and that it would not treat AI-generated falsehoods more leniently than human-generated ones, it ultimately declined to impose a formal sanction under ARCAP 25 because the appellee did not respond to the brief. The court affirmed the lower court's dismissal on the merits, finding the appellant waived her claims by failing to seek injunctive relief prior to the trustee's sale as required by Arizona law.
