Joan Pablo Torres Campos v. Leslie Ann Munoz
CA California · Mar 5, 2026
What happened in this matter?
The court imposed a $5,000 monetary sanction and a mandatory referral to the State Bar of California against attorney Roxanne Chung Bonar for citing and persistently defending fictitious legal authorities, including cases potentially generated by AI tools.
- Why the court cared
- Fabricated: Case Law | Court and counsel cited 'Marriage of Twigg' as authority on prioritizing parties' emotional well‑being in custody; Twigg does not exist and the citation "34 Cal.3d 926" and parallel citations provided by counsel were fabricated. Court found reliance on this nonexistent authority and counsel later admitted Twigg was fictitious. || Misrepresented: Case Law | Counsel cited 'In re Marriage of Teegarden' with an incorrect citation/year and attributed a holding about emotional well‑being and pet custody that the real 1986 Teegarden decision did not hold; the citation and asserted holding were misrepresented.
- Why it matters now
- A single fictitious case plus a misquoted real one triggers a $5K fine and bar referral; mandate partner sign-off on every cited authority.
Why this matter is tracked
The California Court of Appeal sanctioned attorney Roxanne Chung Bonar $5,000 and referred her to the State Bar for citing fictitious legal authorities. Counsel relied on 'Marriage of Twigg,' a nonexistent case sourced from a Reddit article, and misrepresented the holding of 'In re Marriage of Teegarden.' Despite being alerted to the fabrication, counsel doubled down by providing additional bogus reporter citations and a fictitious decision date, later admitting at oral argument that she may have used AI tools to generate the false information. The court emphasized that attorneys have a non-delegable duty to verify the authenticity of every cited authority, particularly when drafting proposed orders or using AI-assisted research tools.
