Coomer v. Lindell: Colorado Court Sanctions Defamation Defense Lawyer $5,000 — His Second AI-Citation Penalty in the Same Case | Advocate Prakhar

Case at a Glance

Background

Eric Coomer, a former Dominion Voting Systems employee, sued Michael Lindell, Frankspeech LLC, and My Pillow, Inc. for defamation after they accused him of rigging the 2020 presidential election. The case went to trial, and the jury delivered a partial verdict for Coomer, including punitive damages against Frankspeech. Defense attorney Christopher Kachouroff had already been sanctioned $3,000 (along with co-counsel Jennifer DeMaster) in the first sanctions order — issued before trial — for filing a brief with “nearly thirty defective citations,” including cases that did not exist, misquotes, and misrepresented holdings, after Kachouroff admitted using AI to draft it.

The AI Issue

After trial, Kachouroff filed a post-trial brief arguing against increasing the punitive damages award. The brief stated: “The 10th Circuit recognized in Capital Solutions, LLC v. Konica Minolta Business Solutions USA, Inc., 695 F.Supp.2d 1149, 1154-56 (10th Cir. 2010)…” — but Capital Solutions is a district court case from Kansas, not a Tenth Circuit case. This is the same type of misattribution error that appeared repeatedly in Kachouroff’s pre-trial brief: citing a case to the wrong court. Beyond the court-level error, the case also does not support the proposition for which Kachouroff cited it. Judge Wang identified this as consistent with AI-generated misattribution, noting that this exact pattern — citing a case correctly but to the wrong court level — appeared multiple times in Kachouroff’s earlier sanctioned brief.

What the Court Decided

• The second order to show cause was made absolute as to Kachouroff — he violated Rule 11(b) again [repeat violation finding].
• The second order was discharged as to co-counsel DeMaster and Frankspeech — Kachouroff was solely responsible for the post-trial brief [individual responsibility].
• Misattributing a district court case as a Tenth Circuit authority is a material misrepresentation — district court cases are not binding on the court [misrepresentation of legal significance].
• A $5,000 sanction was imposed on Kachouroff and his firm McSweeney Cynkar & Kachouroff PLLC, jointly and severally [escalated sanction for repeat violation].
• No bar referral to the Virginia State Bar — the court accepted Kachouroff’s representation that he was withdrawing from active trial work due to health issues [discharge of proposed bar referral].
• Kachouroff’s cumulative sanctions in this single case total $8,000 — within the “normal range” for similar AI citation misconduct nationally [cumulative accounting].

“This is the latest incident in what is now a pattern of Mr. Kachouroff submitting briefs with citations that ‘misrepresent[] what courts have said.'”

— Judge Nina Y. Wang, Coomer v. Lindell, May 7, 2026

The India Angle

Indian Law Equivalent

The principle that misrepresenting the authority level of a precedent is a material error has direct parallels under Indian law. Advocates in India frequently cite High Court decisions before trial courts or cite unreported decisions as if they were reported — both practices can draw judicial criticism. Under the Advocates Act, 1961, Section 35 provides for professional misconduct proceedings before State Bar Councils. Repeated citation misrepresentation, especially if systematic, could constitute misconduct warranting suspension or removal from the roll.

Bar Council Rules

Bar Council of India Rule 22 prohibits advocates from making false statements to the court. A systematic pattern of misattributing cases — as Kachouroff showed — would engage this rule. Additionally, Rule 15 (fair conduct) and Rule 33 (not misleading the court) are directly applicable. Importantly, Rule 14 requires advocates to uphold the dignity and decorum of the court — repeated citation failures in the same case, after sanctions, could be seen as treating the court’s authority with contempt.

Practical Advice for Indian Advocates

• When citing cases, always specify the court level: Supreme Court (binding), High Court (binding in jurisdiction), and their dates — a citation to a lower court decision misleadingly framed as High Court authority is a misrepresentation equivalent to what Kachouroff did.
• After receiving any judicial criticism of your citations, institute an immediate review of all pending briefs — do not wait for a formal sanction order to fix errors in other cases.
• If you routinely use AI in drafting, establish a named verification protocol: every citation must be confirmed in a specified legal database and annotated with the confirming search result before the brief is filed.

Quick Takeaways

• Repeat AI citation failures in the same case bring escalating sanctions — the second offence cost more than the first.
• Misattributing a district court case as a circuit court ruling is a material — not technical — error.
• A cumulative $8,000 sanction in a single case is within the “normal range” nationally; courts are not being lenient.

Deep Dive: The Escalation of Repeat AI Sanctions and the Pattern Problem

Coomer v. Lindell is the most detailed record of a repeat AI-sanctions pattern in a single high-profile case. The first sanctions order — $3,000 against Kachouroff and $3,000 against DeMaster — came after the pre-trial brief contained nearly thirty defective citations, including cases that simply did not exist. Kachouroff admitted AI use. The court found that the “correct version” defence (claiming a wrong draft was accidentally filed) was not credible, because the purported correct version contained its own errors and had a different file naming convention that did not match the drafts exchanged by email.

The second violation is in some ways more telling about how AI misuse persists even after sanctions. The Capital Solutions error is not a case-doesn’t-exist hallucination — it is a misattribution hallucination, where the case exists but is assigned to the wrong court. This is a subtler failure: the attorney can claim he found the case in a legitimate database (and Kachouroff claimed he used only Westlaw for this brief). But Judge Wang’s analysis exposes the weakness of that claim: the error appeared twice in quick succession in the same brief, in the same form, in a way that a human attorney reviewing the brief would have noticed immediately. Any lawyer should recognize that a Federal Supplement citation — the reporter for district court decisions — cannot be a Tenth Circuit case.

The court’s refusal to refer Kachouroff to the Virginia State Bar, because of his health and stated withdrawal from trial practice, shows the balancing act courts perform between deterrence and proportionality. Judge Wang was explicit: the $8,000 cumulative sanction is within the normal national range, and accepting Kachouroff’s withdrawal from trial practice as a practical form of natural deterrence made a bar referral redundant. This pragmatic approach — reserving bar referrals for cases where the attorney continues to practice — gives courts a graduated tool that can be escalated if an attorney does not actually withdraw.

For Indian advocates, the Coomer case makes a specific argument for cross-case citation governance. Kachouroff’s problems were not limited to one brief or even one case — he was simultaneously sanctioned in the Eastern District of Wisconsin (Pelishek v. City of Sheboygan) for similar patterns in a different matter. An advocate who allows systematic AI misuse to infect multiple simultaneous cases faces a compounding risk: each court sees an independent violation, imposing independent sanctions, and the pattern becomes evidence of willful or reckless conduct rather than an isolated mistake. Maintaining a firm-wide citation verification protocol — applied before any brief is filed in any court — is the only systematic protection against this kind of multi-front exposure.
