BKA Holdings v. Sam
CA Illinois · Sep 16, 2025
What happened in this matter?
The court struck the defendants' reply brief and sanctioned them for citing four AI-hallucinated cases. The court awarded the plaintiff attorney fees and costs associated with identifying and litigating the hallucinated authority, with the specific monetary amount to be determined following a subsequent filing of expenses.
- Why the court cared
- The court reasoned that pro se litigants are presumed to know court rules and that the defendants had been previously warned by the trial court about AI-generated research. It determined that the 'flagrant and unprincipled' use of AI to cite non-existent cases constituted an abuse of the adversary system that wasted judicial resources, warranting the striking of the brief and the imposition of sanctions.
- Why it matters now
- This case demonstrates that appellate courts will enforce strict verification standards for AI-generated content even against pro se litigants. It highlights that prior warnings regarding AI use are a significant factor in the court's decision to impose sanctions for repeated reliance on hallucinated authority.
Why this matter is tracked
In this landlord-tenant dispute, the Illinois Appellate Court addressed the defendants' appeal of an eviction order. During the appellate proceedings, the pro se defendants submitted a reply brief containing four citations to non-existent, AI-hallucinated case law. The court rejected the defendants' argument that their pro se status excused this conduct, noting that the trial court had previously warned them regarding the use of AI-generated research. Citing the Illinois Supreme Court's AI policy and the need to prevent abuse of the adversary system, the appellate court struck the defendants' reply brief and granted the plaintiff's motion for sanctions, including an award of attorney fees and costs incurred in researching and challenging the hallucinated authorities.
This case demonstrates that appellate courts will enforce strict verification standards for AI-generated content even against pro se litigants. It highlights that prior warnings regarding AI use are a significant factor in the court's decision to impose sanctions for repeated reliance on hallucinated authority.
