Guo v. Meade Motorcars, LLC
Court of Appeals of Ohio, Sixth Appellate District (Sandusky County) · Ohio Ct. App. (6th Dist.) · Ohio bar guidance
Conduct
Pro se judgment creditor cited five nonexistent or misquoted Ohio cases and, when challenged, insisted they were real and faulted opposing counsel.
Consequence
Trial court's $100 sanction stands; appeals court affirmed denial of his motion to vacate it, rejecting his Deepseek and limited-access explanations.
Lesson
The court held that pro se status and limited access to Ohio legal resources are no defense; Guo's insistence the cases were real undercut his claim of prompt correction.

Summary
Xingkui Guo, "at all times appearing pro se," registered a Tennessee default judgment against Ohio car dealer Meade Motorcars, LLC in Sandusky County, and Meade moved to vacate for lack of personal jurisdiction. In a June 26, 2025 filing, Guo cited "Davis v. Davis, 590 N.E.2d 1372 (Ohio Ct. App. 1990)"; Meade requested sanctions, saying it could not find Davis even with a law librarian's help and identifying three other citations it could not find. In his July 10, 2025 opposition to that request, Guo cited Davis, "Kaplan v. Tuennerman," "Black v. Black," and "Brunswick Hills Twp. v. Bank of New York," insisting they were "readily accessible to any attorney who exercises due diligence"; his July 21, 2025 motion to set aside cited "Moran v. Moran, 2012-Ohio-1841." The court of appeals found the cases "do not exist at those citations. Some of them do not exist at all," and the others do not contain the quotations or support the propositions. The trial court vacated the foreign judgment and, on August 11, 2025, found Guo "has simply made them up" and awarded Meade $100 in sanctions. Guo moved to vacate the sanction, citing restricted access to legal research in China; on appeal he attributed the mis-citations to his use of "Deepseek" and limited access to Ohio-specific legal research tools.
- AI tool:
- Deepseek (the appellant's own explanation on appeal, as recounted by the court; the court found the citations "appear to be the result of AI-generated hallucinations")
- Sanction amount:
- $100 (imposed by the Sandusky County Court of Common Pleas on Aug. 11, 2025; the court of appeals affirmed the denial of the motion to vacate it)
What sanction did the court impose?
The Sixth District (Sulek, J., with Mayle and Zmuda, JJ., concurring) affirmed. Because Guo appealed only the denial of his Civ.R. 60(B) motions and not the August 11, 2025 sanctions judgment, the court reviewed whether he had a meritorious defense to the sanction, and held he did not. Citing the courts' inherent authority to sanction abuse of the judicial process, and Ohio appellate decisions imposing sanctions for hallucinated citations, it held: "It is no defense that Guo is a pro se litigant with limited availability to Ohio-specific legal resources," and "Guo had an obligation to verify that the cases and law he was presenting to the court were real and not a fabrication." It noted that, contrary to his appellate claim of prompt correction, Guo's response when confronted was "to affirm that the citations existed and to chastise Meade's attorney." The court also rejected his challenges to the vacatur of the Tennessee judgment and to the denial of his own sanctions motions, and ordered him to pay the costs of the appeal.
Why does Guo v. Meade Motorcars, LLC matter for law firms using AI?
Guo v. Meade Motorcars is a small-dollar sanction with a clear appellate holding: pro se status and limited access to Ohio-specific legal resources are no defense to sanctions for hallucinated citations. Guo cited five cases for a single proposition about foreign judgments. Meade’s counsel, even with the help of a law librarian, could not find the first of them and identified three others that could not be found; the court of appeals later could not locate the fifth. The Sixth District’s summary is direct: the cases “do not exist at those citations. Some of them do not exist at all. And where the others do exist, they do not include the quotations provided by Guo, nor do they stand for the propositions for which they were cited. In all respects, they appear to be the result of AI-generated hallucinations.”
What sank Guo’s appeal was his response when challenged. Rather than check the citations, he told the trial court they were “readily accessible to any attorney who exercises due diligence” and moved for sanctions against Meade’s counsel. On appeal he claimed that once the issue was identified he “promptly acknowledged and corrected the error,” which the court found contrary to the record. His explanations, in the trial court that research tools such as Google are banned in China, where he was at the time, and on appeal that the mis-citations came from “Deepseek,” did not change the result; the court held that pro se litigants are “presumed to have knowledge of the law and legal procedures” and are held to the same standard as represented parties.
The procedural posture matters too. Guo appealed only the denial of his Civ.R. 60(B) motion to vacate the sanction, so the court reviewed the matter as a question of whether he had shown a meritorious defense, rather than reviewing the sanction directly. Firms documenting compliance may wish to consider both lessons when a challenged citation surfaces: verify first, and respond on the merits of what verification shows.
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.
- Verify any case an opponent says cannot be found before responding. Guo's insistence that the cases were 'readily accessible' undercut his later claim that he promptly corrected the error.
- Review the scope of any appeal from a sanctions ruling. Guo did not appeal the sanctions judgment itself, which limited the court to asking whether his Civ.R. 60(B) motion showed a meritorious defense.
- Document the basis for a sanctions request that rests on fabricated authority. Meade reported that it could not find Davis even with a law librarian's help and identified three other citations it could not find; the trial court granted sanctions after a hearing whose transcript is not in the appellate record.
