Patterson v. Nuvision Credit Union
CA California (4d) · Jul 2, 2026
What happened in this matter?
The court sanctioned a pro se litigant $500 (suspended) and referred her to the State Bar for the unauthorized practice of law after she filed an appellate brief containing multiple fabricated cases and false quotations, which she attributed to her reliance on outside research assistance without verification.
- Why the court cared
- The court reasoned that the litigant violated rule 8.204(a)(1)(B) by failing to support points with real authority. It determined that pro se litigants are held to the same standards as attorneys regarding citation verification, and that the litigant's failure to address fabricated quotations or take corrective action after receiving notice of similar issues in a related case warranted sanctions and a bar referral.

Why this matter is tracked
In this appellate matter, a pro se litigant filed an opening brief containing numerous fabricated case citations and nonexistent quotations, which the court identified as hallmarks of generative AI. The court issued an order to show cause regarding these rule violations. Although the litigant admitted to failing to verify citations and apologized, the court found her response insufficient, noting she failed to address the fabricated quotations and demonstrated a lack of corrective action despite prior warnings in a related case. The court concluded the litigant unreasonably violated California Rules of Court, rule 8.204(a)(1)(B), by failing to support arguments with real authority. Consequently, the court imposed a $500 monetary sanction, suspended its execution, and referred the litigant to the State Bar for the unauthorized practice of law.
