Corrales v BPG Inspection
CA Colorado · Jul 2, 2026
What happened in this matter?
The Colorado Court of Appeals admonished a pro se litigant for including GAI-generated hallucinations—specifically, citations to nonexistent cases—in her appellate brief. The court declined to impose formal sanctions, such as striking the pleading or monetary penalties, but explicitly warned the litigant regarding the submission of fabricated legal authorities.
- Why the court cared
- The court reasoned that while it possesses the authority to impose sanctions under C.A.R. 38(a) for failing to comply with appellate rules, it chose to exercise its discretion to admonish the litigant rather than impose formal sanctions, noting a similar approach taken in prior state appellate precedent.
- Why it matters now
- This case illustrates the judiciary's increasing willingness to explicitly identify and admonish the use of GAI-generated hallucinations in legal filings, even when the litigant is pro se and the court opts against formal sanctions.
Why this matter is tracked
In this appellate matter, the Colorado Court of Appeals affirmed the district court's dismissal of a pro se complaint due to the plaintiff's failure to perfect service of process. During the appellate proceedings, the court identified that the plaintiff's opening brief contained citations to at least one nonexistent case, which the court explicitly attributed to generative artificial intelligence (GAI) hallucinations. While the court noted its authority to impose sanctions under C.A.R. 38(a) for non-compliance with appellate rules, it declined to impose formal sanctions. Instead, the court issued a formal admonishment to the plaintiff regarding the submission of GAI-generated hallucinations in her filings. The underlying judgment regarding the dismissal of the complaint was affirmed.
This case illustrates the judiciary's increasing willingness to explicitly identify and admonish the use of GAI-generated hallucinations in legal filings, even when the litigant is pro se and the court opts against formal sanctions.
