In re Lisa Cato
U.S. Bankruptcy Court, District of Columbia · Bankr. D.D.C. · District of Columbia bar guidance
Conduct
A pro se petition preparer filed a sanctions motion the court called riddled with fabricated legal citations; the court had since ordered him to certify AI use on future filings.
Consequence
Here the court denied his motion for failure to follow the Rule 9011 safe harbor and on the merits, and noted the hallucinated caselaw may violate Rule 9011(b).
Lesson
Here the court, having imposed a per-filer AI certification, warned that continued hallucinated caselaw may violate Rule 9011(b), without sanctioning.

Summary
Robert Miller, the bankruptcy petition preparer for debtor Lisa Cato, was the subject of a U.S. Trustee motion to disgorge fees and impose fines under 11 U.S.C. § 110, which the court granted and Miller appealed. While that motion was under advisement, on or about December 3, 2025, Miller filed, pro se, a motion seeking sanctions against the Trustee (ECF No. 39). The court described it as "riddled with muddled argument, fabricated legal citations, and arguments already addressed by the Court." A footnote states that it was "not the first instance" of Miller "using incorrect citations, fabricated quotations, or misstatements of law," and cites an order (ECF No. 83), entered after the motion was filed, that required all of Miller's future filings to be accompanied by a "certification stating whether generative AI was used in the drafting process and confirming that Mr. Miller conducted a separate, independent review prior to the filing verifying the accuracy of all citations therein." The footnote adds that "[t]he continued use of hallucinated caselaw undermines Mr. Miller's legal assertions and arguments and may violate Bankruptcy Rule 9011(b)." At the March 25, 2026 hearing Miller pressed only two points: that the Trustee's certificate of service was invalid because a paralegal signed it, and that a reference to a past charge against him was inadmissible hearsay.

What did the court warn about?
The court denied Miller's sanctions motion. It held that Miller did not comply with the 21-day safe-harbor requirement of Bankruptcy Rule 9011(c), a mandatory prerequisite to any award of sanctions, and that his arguments failed on the merits in any event: nothing in Civil Rule 5 requires an attorney to sign a certificate of service, a missing or defective certificate would not void the underlying motion or order, and allegations in a pleading are not evidence to which the Rules of Evidence apply. The cases Miller cited for the certificate-of-service point were, the court found, real but distinguishable. Arguments in the motion that Miller did not pursue at the hearing were deemed abandoned, and arguments going to the merits of the disgorgement order were outside the court's jurisdiction while his appeal is pending. This order imposes no sanction on Miller for the fabricated citations; it notes that their continued use "may violate" Rule 9011(b).
Why does In re Lisa Cato matter for law firms using AI?
This order is a denial of a sanctions motion, and the AI material sits in its first footnote. The court describes the motion that Robert Miller, the debtor’s bankruptcy petition preparer, filed against the U.S. Trustee as containing fabricated legal citations, and it records that the court had, in an order entered after the motion was filed, required Miller to attach to every future filing a certification stating whether generative AI was used and confirming his own independent review of every citation. The footnote then observes that “[t]he continued use of hallucinated caselaw” undermines his arguments “and may violate Bankruptcy Rule 9011(b).”
The disposition rests on ordinary grounds. Miller did not serve the motion 21 days before filing it, as Bankruptcy Rule 9011(c) requires, and the court treated that failure as dispositive. It went on to reject his two remaining arguments on the merits: a paralegal may sign a certificate of service, and a statement in a pleading is not evidence. The court noted that the cases Miller cited on the certificate point were accurate statements of the law that simply did not address the question.
The matter illustrates a court responding to citation problems by a nonlawyer filer with a per-filer AI certification directive and a footnote admonition about potential Rule 9011(b) exposure. This order does not itself impose a sanction for the citations. Firms documenting compliance may wish to consider how certification directives of this kind apply to nonlawyer preparers whose filings they review.
Implications for your firm
Operational steps a firm reading this case may wish to consider documenting. Strategic and rule-application calls belong to your firm's attorneys.
- Review filings by non-attorney preparers and other nonlawyer drafters with particular care. Here the court required this petition preparer to certify AI use and independent citation review on every future filing.
- Verify the procedural prerequisites before seeking sanctions against an opponent. The court denied the motion because the 21-day safe-harbor notice under Bankruptcy Rule 9011(c) was not given.
- Document citation checks even when a certification order is in place. The court noted that continued use of hallucinated caselaw may violate Rule 9011(b).
