Villanueva v. Bowers
CA Arizona (1d) · Jun 11, 2026
What happened in this matter?
The Arizona Court of Appeals sanctioned a pro se appellant for submitting AI-generated briefs containing fabricated legal citations. The court awarded the appellee reasonable attorney fees and costs as a sanction for the appellant's unreasonable conduct and failure to verify the accuracy of the AI-generated content.
- Why the court cared
- The court reasoned that the appellant's conduct was unreasonable because she presented false and inapposite legal authority and, when confronted, lied to the court in her reply brief instead of admitting to the use of artificial intelligence.
- Why it matters now
- This case illustrates the appellate court's willingness to impose financial sanctions on pro se litigants who use generative AI to produce briefs without verifying the accuracy of the cited legal authorities.
Why this matter is tracked
In an appeal regarding child support, the appellant, appearing pro se, submitted briefs containing numerous citation errors, including non-existent cases, impossible pin cites, and misdated memorandum decisions. When challenged by opposing counsel, the appellant initially denied the errors. The Arizona Court of Appeals ordered a supplemental brief, at which point the appellant confessed to using generative artificial intelligence to draft the briefs without verifying the citations. The court found the appellant's conduct on appeal unreasonable, noting that she doubled down on the false citations before admitting to the AI usage. Consequently, the court awarded the appellee reasonable attorney fees and costs under A.R.S. § 25-324 and ARCAP 25, while vacating and remanding the underlying child support order on other grounds.
This case illustrates the appellate court's willingness to impose financial sanctions on pro se litigants who use generative AI to produce briefs without verifying the accuracy of the cited legal authorities.
