Patel v. Patel

U.S. District Court, Western District of Kentucky, Owensboro Division · W.D. Ky. · Kentucky bar guidance

Conduct

Petitioners' response to a motion to dismiss contained citations and quotations the court said appear to be generative AI hallucinations.

Consequence

Here the court accepted both attorneys' sworn explanations and apologies, declined to impose sanctions, and admonished them not to repeat the errors.

Lesson

In this case, sworn explanations the court found satisfactory, a finding that the errors were not intentional, and no disciplinary history led the court to warn rather than sanction.

Summary

In reviewing the petitioners' Response to Respondents' Motion to Dismiss (DN 61), the court "identified a series of citations and quotations that appear to be generative artificial intelligence ("AI") hallucinations." Its May 28, 2026 Show Cause Order (DN 65) listed five items by page of the response: Cummings v. Pitman (page 8), a quotation attributed to Miller v. Currie (page 19), a quotation attributed to Grable & Sons Metal Products, Inc. v. Darue Engineering & Manufacturing (page 20), a parenthetical attributed to Yegiazaryan v. Smagin (page 21), and a quotation attributed to Reiter v. Sonotone Corp. (page 24). The order does not say which defect applies to which item. It directed petitioners' counsel, Daniel N. Thomas and Mary E. Jocelyn, to show cause why they should not be sanctioned under Fed. R. Civ. P. 11(b)(2) and (c) and the court's inherent power "for providing false citations, attributing apparently fictitious quotations to court decisions, and misrepresenting the holdings of various cases, apparently in reliance on AI-generated content," and required sworn declarations from both explaining how the response came to cite nonexistent cases and quotations and what role each played in drafting or reviewing it. Each attorney filed a declaration (DN 66-1, DN 66-2).

AI tool:
Suspected generative AI (the show-cause order says the citations and quotations "appear to be generative artificial intelligence ('AI') hallucinations" and refers to "apparently" relying on AI-generated content); the July 7 order does not say whether counsel admitted AI use; no tool named
Amount or terms:
None; the court found the show-cause order satisfied, declined to impose sanctions, and admonished both attorneys

What did the court warn about?

In a three-page Memorandum Opinion and Order entered July 7, 2026 (DN 68), the court found the attorneys' "explanations satisfactory and their apologies genuine." It reasoned that because their "use of improper citations and quotations was not intentional and, to the Court's knowledge, neither attorney has a history of misconduct, a warning is a sufficient deterrent in this case," citing the Kentucky Bar Association's lawyer directory in a footnote for the absence of a disciplinary history. Thomas and Jocelyn were "admonished to ensure that these errors are not repeated." The court ordered that the Show Cause Order "has been satisfied" and declined to impose sanctions. Before reaching that result, the order reviewed the Rule 11 factors from the Advisory Committee Notes and noted that other courts have imposed sanctions where attorneys continue to rely on nonexistent citations after notice or have a history of similar misconduct. The same day, in a separate memorandum opinion (DN 67), the court granted in part and denied in part the respondents' motions to dismiss.

Why does Patel v. Patel matter for law firms using AI?

The court’s handling of this matter followed a two-step pattern: a written show-cause order that identified the problem items by page, then a short disposition once counsel responded. The show-cause order is specific about what it wanted to know. Each attorney had to address, under oath, how the response “came to cite case(s) that do not exist, cite quotations that do not exist, and cases that do not stand for the propositions cited,” and what role each “individually played in drafting or reviewing the response before it was filed.” It also cited Kentucky Bar Association Ethics Opinion E-457 for the duty to review AI-assisted submissions for accuracy.

The disposition turned on the factors the court named: it found the explanations satisfactory and the apologies genuine, found the use of improper citations and quotations “not intentional,” and found no history of misconduct “to the Court’s knowledge.” On that record the court concluded that “a warning is a sufficient deterrent in this case.” The order does not describe what the declarations said, so it does not establish whether or how AI was used; the AI attribution rests on the court’s own “appear to be” and “apparently” language in the show-cause order.

The order also collects the court’s view of the surrounding case law, including the Sixth Circuit’s statement in United States v. Farris that attorneys who use AI tools must verify the citations and propositions they submit, and it notes that other courts have imposed sanctions where attorneys persisted after notice or had a history of similar conduct. Firms documenting compliance may wish to consider how a sworn, individual account of the drafting and review process figured in this court’s decision to warn rather than sanction.

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.

  • Document who drafted and who reviewed each filing. The show-cause order required a sworn declaration from each of the two attorneys on the response describing what role, if any, each played in drafting or reviewing it.
  • Verify quotations and parentheticals, not only case names. Four of the five items the court listed were quoted language or a parenthetical attributed to the cited decision, three of them to U.S. Reports citations.
  • Consider that the court looked at the attorneys' public disciplinary record. The order cited the Kentucky Bar Association's lawyer directory for its statement that neither attorney has a history of misconduct, one of the reasons it gave for a warning.

  • Whether counsel used generative AI: the show-cause order says the items "appear to be" AI hallucinations and refers to "apparently" relying on AI-generated content; the July 7 order does not recount what the declarations (DN 66-1, DN 66-2) said, and they were not read.
