In re Lisa Cato
D. D.C. (Bankruptcy) · Jul 10, 2026
What happened in this matter?
The court denied the motion for sanctions because the movant failed to comply with the mandatory safe harbor notice requirements of Bankruptcy Rule 9011(c). Additionally, the court determined the movant's substantive arguments regarding the validity of a certificate of service and the admissibility of pleading allegations were legally meritless.
- Why the court cared
- The court reasoned that the motion was procedurally barred by the failure to provide the mandatory 21-day safe harbor notice required by Bankruptcy Rule 9011(c). On the merits, the court found the movant's arguments regarding the validity of a paralegal's signature on a certificate of service and the application of the Rules of Evidence to pleading allegations were legally flawed and unsupported by the cited authorities.
- Why it matters now
- This case illustrates judicial scrutiny of pro se filings involving hallucinated caselaw and the enforcement of procedural prerequisites like the Rule 9011 safe harbor. It highlights the court's reliance on prior orders requiring AI-use certification to manage recurring citation inaccuracies.
Why this matter is tracked
The U.S. Bankruptcy Court for the District of Columbia denied a pro se litigant's motion for sanctions against the United States Trustee. The court found the motion procedurally deficient for failing to comply with the mandatory 21-day safe harbor provision of Bankruptcy Rule 9011(c). Furthermore, the court observed that the motion contained fabricated legal citations and misstatements of law, noting this was not the first instance of such conduct by the movant. The court had previously ordered the movant to certify the use of generative AI and verify the accuracy of all citations in future filings. The court concluded the movant's arguments were meritless, indecipherable, or abandoned, and denied the motion in its entirety.
