Harris v. Pinnacle Bank — N.D. Mississippi, May 7, 2026
Pro se plaintiff Joshua Harris submitted AI-fabricated citations in four separate filings, was called to three show cause hearings, received explicit Rule 11 findings, and was warned that future violations would result in dismissal. He then filed another fabricated-citation motion the day before his third show cause hearing. At that hearing, he admitted the conduct and conceded dismissal was appropriate. The court dismissed the case with prejudice.
Why it matters: This is the clearest judicial statement yet that dismissal with prejudice is the appropriate outcome for a pattern of wilful, repeated AI-hallucination misconduct despite multiple explicit warnings.

Background
Joshua Harris filed a pro se FCRA complaint against Pinnacle Bank in May 2025, asserting credit reporting violations and breach of contract. The case quickly became dominated by Harris’s repeated filing of AI-fabricated citations. The misconduct unfolded across four filings and three separate show cause hearings over approximately five months.
The first instance arose in Harris’s opposition to a consolidation motion in October 2025: he cited a non-existent case (“United States v. Mississippi Power & Light Co.”) and attributed language to a real case (Dupont v. Southern Pacific) that does not appear in that opinion. Pinnacle Bank notified Harris of the errors; he declined to correct them. After the court’s first show cause hearing in December 2025, it found a Rule 11 violation but declined to impose sanctions — warning that any further violation could result in dismissal.
Harris then filed a Motion to Compel citing four non-existent authorities, triggering a second show cause hearing. The court denied the motion and issued a second order to show cause with another explicit dismissal warning. Then, the day before his third show cause hearing, Harris filed a Motion to Vacate containing two non-existent local rules and misrepresented three Federal Rules of Civil Procedure. At the April 29, 2026 show cause hearing, Harris admitted submitting incorrect, fictitious, and AI-generated citations and conceded that dismissal was appropriate.
The AI Issue
The accumulated misconduct in Harris v. Pinnacle Bank represents the most extensive documented pattern of AI-hallucination filing abuse in the reported case law. Four separate filings, across six months, each containing fabricated legal authority. Three separate show cause hearings. Two explicit Rule 11 findings with warnings. Harris admitted at the final hearing that he had submitted incorrect and fictitious citations and that he had failed to verify their authenticity. He had also failed to respond to defendant’s Motion to Dismiss despite explicit court instructions that the stay order did not excuse him from doing so.
What the Court Decided
- Case dismissed with prejudice under Rule 41(b) and inherent authority for pattern of delay, contumacious conduct, and disregard for court orders.
- Court found plaintiff acted at minimum with reckless disregard, and given the repeated warnings and repeat conduct, found the conduct wilful and in bad faith.
- Defendant’s Motion to Dismiss / Motion for Sanctions and plaintiff’s Motion to Vacate denied as moot following dismissal.
- Defendant permitted to file a motion for additional monetary sanctions (attorneys’ fees and costs) within 14 days.
- Court found lesser sanctions inadequate: plaintiff had already been found to violate Rule 11, had been warned twice of dismissal as a consequence, had received three show cause hearings, and had nonetheless filed fresh fabricated citations the day before the third hearing.
“Despite explicit warnings from the Court, Plaintiff repeatedly submitted filings containing fabricated legal authority and inaccurate representations of existing authority. This misconduct persisted even after the Court found that Plaintiff had violated Rule 11 and expressly warned Plaintiff that future violations could result in dismissal.”

The India Angle
Indian Law Equivalent
Dismissal with prejudice under Rule 41(b) has its closest Indian analogue in Order IX Rule 8 CPC (dismissal for non-prosecution) and Order XVII Rule 3 CPC (dismissal for wilful default). Importantly, Indian courts have exercised their inherent powers under Section 151 CPC to dismiss suits filed in abuse of the court’s process, including where parties have repeatedly misled the court. Under the Contempt of Courts Act, 1971, a party who repeatedly violates court orders (equivalent to the three show cause orders in this case) can be sentenced to imprisonment as well as fined.
Bar Council Rules
Section 35 of the Advocates Act, 1961, empowers the Bar Council to suspend or debar an advocate found guilty of professional misconduct. The pattern in Harris v. Pinnacle Bank — four fabricated filings despite explicit findings and warnings — would be treated as the most serious category of professional misconduct under BCI disciplinary proceedings. The absence of a financial penalty in the final order (since Harris was pro se) does not affect the parallel disciplinary analysis: an advocate who engaged in the same conduct would face the full range of Bar Council sanctions.
Practical Advice for Indian Advocates
- A client who has received a Rule 11 or equivalent warning about citation fabrication must be advised in the strongest possible terms that any further violation will result in dismissal of their case — not just a fine — and that this consequence cannot be avoided by apology or technicality.
- When courts have previously identified AI-hallucination errors in your filings, implement a mandatory pre-filing citation check for every subsequent submission in every related case — the court will be watching, and the same error will escalate consequences dramatically.
- Do not file new motions the day before a show cause hearing relating to prior AI errors — this demonstrates the most extreme form of disregard for court authority and will virtually guarantee the most severe available sanction.
Quick Takeaways
- Four AI-hallucination filings, three show cause hearings, two prior Rule 11 findings, and two explicit dismissal warnings — the court’s patience runs out and dismissal with prejudice follows.
- Filing fresh fabricated citations the day before a show cause hearing about prior fabricated citations is the most self-defeating act a litigant can perform — courts treat it as evidence of wilful bad faith.
- Plaintiff’s own admission that dismissal was appropriate gave the court the cleanest possible record for imposing the most severe sanction.
Deep Dive: The Proportionality Analysis — How Courts Reach Dismissal With Prejudice for AI Misconduct
Courts do not dismiss cases lightly. Dismissal with prejudice is the most severe sanction available in civil proceedings because it permanently extinguishes the plaintiff’s claim, with no right to refile. The law governing this sanction requires courts to consider whether lesser sanctions would adequately address the misconduct, whether the party had fair notice, and whether the conduct was wilful rather than inadvertent. The Harris v. Pinnacle Bank case represents the most exhaustively documented pathway to this outcome in the AI-hallucination context.
The proportionality analysis here was straightforward because of the escalation pattern. The court had imposed no sanction at the first show cause hearing — giving Harris a clean slate with only a warning. Harris then filed fresh fabricated citations in a new motion. The court again imposed no monetary sanction at the second show cause hearing, only issuing another warning with an explicit dismissal threat. Harris again filed fresh fabricated citations. At the third show cause hearing, the court had fully exhausted the lesser-sanction options: it had tried warnings, explicit dismissal threats, Rule 11 findings, and repeated reminders of the obligation to verify citations. None of it changed the behaviour.
This escalation pattern — warning, warning, warning, dismiss — is the judicial standard for ensuring that dismissal is proportionate. It provides a clear record showing that lesser sanctions were tried (or genuinely considered and found inadequate), that the party had repeated, explicit notice of the consequences, and that the conduct was the product of at least reckless if not wilful disregard for professional obligations.
For advocates advising clients who have received initial AI-hallucination warnings, the message of Harris v. Pinnacle Bank is urgent: that first warning is the most valuable second chance the court will give. The workflow that generated the fabricated citation must be changed before any further filing is made. If the AI tool is the problem, it must not be used for citation generation without independent verification. If the verification step is being skipped, it must become mandatory. The case law now shows unambiguously where the failure to change the process leads.
