- Why the court cared

- Why it matters now
- This case illustrates judicial scrutiny of AI-assisted or otherwise inaccurate legal research in state appellate courts. It reinforces that counsel bears ultimate responsibility for the veracity of all citations, regardless of the tools used to generate them.
Why this matter is tracked
In an appeal regarding a workers' compensation claim, the Colorado Court of Appeals identified that counsel for the petitioner included multiple false quotations in the opening brief. Specifically, counsel attributed a quotation to Pinkstaff v. Black & Decker (U.S.) Inc. that does not appear in that decision, and the court noted that Pinkstaff is not a workers' compensation case. The court identified additional misquoted cases in the brief but did not itemize them. While the court declined to impose formal sanctions in this instance, it issued a formal warning to counsel, stating that future submissions containing false quotations—whether generated by artificial intelligence or otherwise—may result in sanctions.
