Nelson v. Derry
Minnesota · Apr 15, 2026
What happened in this matter?
The Minnesota Court of Appeals identified that a pro se litigant submitted a fake, hallucinated case citation ('DeMars v. DeMars') in his appellate brief. The court explicitly flagged this as an example of AI-generated hallucinations, noting that such nonexistent cases are increasingly appearing in filings, and relied on federal precedent to characterize the nature of the error.
- Why the court cared
- The court reasoned that the citation was nonexistent and linked the error to the known phenomenon of AI-generated hallucinations, referencing federal case law (Willis v. U.S. Bank Nat'l Ass'n) to contextualize the prevalence of fake citations in modern litigation.
- Why it matters now
- This case illustrates the judicial response to AI-hallucinated citations in pro se filings. It demonstrates that courts are increasingly identifying and documenting the use of AI-generated fake authorities, providing a clear record of how such errors are addressed within appellate opinions.
Why this matter is tracked
In a family law appeal, the Minnesota Court of Appeals addressed arguments raised by a pro se litigant, Abel Aaron Nelson. During the proceedings, the appellant cited 'DeMars v. DeMars, 590 N.W.2d 116, 120-21 (Minn. Ct. App. 1999).' The court was unable to locate this case and explicitly noted that the citation appeared to be a hallucinated, nonexistent case. The court referenced the growing trend of AI-generated hallucinations in legal filings, citing recent federal jurisprudence on the issue. The court ultimately affirmed the district court's order regarding the execution of a Qualified Domestic Relations Order (QDRO), finding no abuse of discretion or due process violations in the lower court's handling of the matter.
