Why this matter warrants attention
The Colorado Court of Appeals issued a formal warning to pro se litigants after identifying briefs replete with citation errors and mischaracterized case law, which the court attributed to the potential use of generative artificial intelligence. The court cautioned that future filings containing errors caused by GAI could result in sanctions.
The court inferred GAI usage from the presence of repeated citation errors, references to nonexistent quotes, and incorrect statements about cases, noting that the cited cases did not support the propositions for which they were offered.
This case illustrates judicial scrutiny of pro se filings for AI-generated hallucinations. It reinforces the expectation that litigants, regardless of representation status, must verify the accuracy of all legal citations and propositions derived from AI tools.

Controls suggested by the public record
- Implement mandatory verification protocols for all legal citations and case law summaries generated by AI tools.
- Review all AI-assisted drafts for hallucinations, including nonexistent quotes and mischaracterized legal holdings.
- Ensure that pro se litigants or junior staff are trained on the risks of AI confidence in generating inaccurate legal information.
