Why this matter is tracked
In this administrative appeal, the pro se plaintiff submitted an appellate brief containing numerous fictitious case citations, fabricated judicial holdings, and references to non-existent record page numbers and exhibits. The court determined these errors resulted from the plaintiff's unprincipled use of artificial intelligence. Despite being warned of these issues during trial court proceedings, the plaintiff repeated the conduct on appeal. The Illinois Appellate Court found that the plaintiff's failure to verify AI-generated content violated Illinois Supreme Court rules regarding brief preparation and accuracy. Consequently, the court granted the defendant's motion for sanctions, ordered the plaintiff's appellate brief stricken, and dismissed the appeal.
