The Fifth Circuit recently decided Fletcher v. Experian Information Solutions, LLC No. 25-00086, (January 6, 2026) itself an appeal dealing with a sanctions issue. Unfortunately, the court noticed potentially spurious or hallucinated citations in the reply brief and issued an order to show cause. On February 18, 2026, the court sanctioned counsel $2500. This is the pertinent discussion:
“But a problem remained. Counsel for plaintiff and a member of the Jaffer & Associates law firm, had filed a reply brief on appeal containing numerous inaccurate citations, quotations, and statements of fact. We issued a show-cause order, enumerating 16 instances of fabricated quotations and 5 additional serious misrepresentations of law or fact. We directed Counsel, the only attorney to sign the brief, to “explain whether and how she verified the accuracy of the propositions in her brief.” We strongly suspected that Counsel had used AI to draft a substantial portion—if not the entirety—of her brief.
Counsel’s response was disappointing. She asserted that she had “relied on publicly available versions of the cases, which [she] believed were accurate.” Believing that response to be incredible on its face, the court directed Counsel to answer additional questions. Counsel answered these questions, noting that she “endeavored to answer each question directly and transparently.” We address each question and Counsel’s response in turn.
First, when asked when she became aware of the inaccuracies in the brief, Counsel replied that it was at the time of our show-cause order. We do not at this time have reason to doubt that Counsel first became aware of the inaccuracies when we pointed them out. Of course, if Counsel had discovered the inaccuracies in her reply brief in the three months between its submission and our show-cause order, she should have immediately alerted the court and sought leave to file a correct brief.
Second, when asked what “publicly available versions of the cases” had led to the inaccuracies described above, Counsel named several well-known legal databases. The court does not find it credible that these sources produced the hallucinated quotations that appeared in Counsel’s brief. The first source, Google Scholar, does not contain summaries of legal cases that could contain inaccurate quotes. While the second, third, and fourth sources—CourtListener, Justia, and FindLaw—do provide legal case summaries, we have reviewed the summaries for each case cited in Counsel’s reply brief, and the problematic quotations and propositions are nowhere to be found. The remaining two sources, Casetext, which has been spun off into Thomas Reuter’s CoCounsel, and vLex, are both generative AI products.
To the extent these products generated the inaccurate summaries, Counsel’s response is misleading in several respects. For one, in her initial response, Counsel stated that she relied on “publicly available versions of the cases” and that “certain paraphrased summaries did not match the reporter text.” Neither of these descriptions fairly characterizes an AI-generated sentence. In addition, if these products generated the hallucinated quotations, they are not fairly characterized as “free online case repositories,” the use of which phrase suggested that these quotations came from summaries posted that could lead others astray. Further, Counsel did not even mention AI in her first response to the court.
Third, when asked specifically about whether she used AI and how she verified the accuracy of the case citations, Counsel finally admitted to the use of AI, though she neglected to do so in her initial show-cause response. We do not find it credible that Counsel used AI solely to “help organize and structure [her] arguments and to break up overly long paragraphs.” Even when asked directly, Counsel did not explain the steps she took to verify the factual assertions in her brief, so the court concludes that she took none.
Fourth, when asked about inaccurate assertions of record facts, Counsel provided no explanation of how “publicly available sources” could have caused record facts to be inaccurate. She had two such factual misstatements in her reply brief.
Fifth, when asked how the paraphrased summaries caused the inaccurate citations and quotations, Counsel continued to attribute the inaccurate quotations to “paraphrased summaries,” which she claims to have “mistakenly believed . . . reflected the actual language of the cases.” However, Counsel did not point this court to a single one of those summaries. We have put tremendous effort into attempting to find where these summaries could be located and have been unable to find them. To the extent Counsel is referring to a case summary generated by AI as a “paraphrased summar[y],” her response is evasive, misleading, and sanctionable.
In sum, the court finds that Counsel used artificial generative intelligence to draft a substantial portion—if not all—of her reply brief and failed to check the brief for accuracy. It is also likely that she used artificial generative intelligence in her response to the show-cause order. Had Counsel accepted responsibility and been more forthcoming, it is likely that the court would have imposed lesser sanctions. However, when confronted with a serious ethical misstep, Counsel misled, evaded, and violated her duties as an officer of this court.
Modern generative AI may be a new technology, but the same sanctions rules apply, and the rules we have are well equipped to handle these types of cases.[10] First, Rule 46(c) allows us to discipline an attorney who practices before us for “conduct unbecoming a member of the bar or for failure to comply with any court rule.” Discipline under Rule 46(c) may include monetary sanctions. In re Violation of Rule 28(d), 635 F.3d 1352, 1360 (Fed. Cir. 2011); see 16AA Wright & Miller’s Federal Practice and Procedure § 3992.2 (5th ed. 2025).
Conduct “unbecoming a member of the bar” is broad and includes making frivolous arguments and misrepresenting facts or law. See, e.g., United States v. Martinez-Martinez, 1999 WL 1330642, at *1 (5th Cir. Dec. 15, 1999) (show-cause order under Rule 46(c) for misrepresenting “a critical fact relating to jurisdiction”); Waldon v. Wal-Mart Stores, Inc., Store No. 1655, 943 F.3d 818, 825 (7th Cir. 2019) (noting that “conduct unbecoming a member of the bar” includes “deliberately misleading the court or displaying egregious misjudgment”).
The conduct at issue in this case is certainly “unbecoming a member of the bar.” Fed. R. App. P. 46(c). As discussed above, Counsel failed to check her own brief before submitting it, leading her to repeatedly misrepresent the law to the court. Cf. Fed. R. Civ. P. 11(b) and (c) advisory committee’s note to 1993 amendment (“The rule . . . require[s] litigants to `stop-and-think’ before initially making legal or factual contentions . . . . A litigant’s obligations . . . include reaffirming to the court and advocating positions contained in those pleadings and motions after learning that they cease to have any merit.”); Tex. Disciplinary Rules Prof’l Conduct R. 3.01 (“A lawyer shall not . . . assert or controvert an issue [in a proceeding], unless the lawyer reasonably believes that there is a basis for doing so that is not frivolous.”); Id. 3.03(a)(1) (“A lawyer shall not knowingly . . . make a false statement of material fact or law to a tribunal”); Id. 8.04(a)(3) (A lawyer shall not “engage in conduct involving dishonesty, fraud, deceit[,] or misrepresentation”).
Second, we have the “inherent power to impose sanctions for abuse of the judicial process.” Anderson, 953 F.3d at 315; see also Amarsingh v. Frontier Airlines, Inc., 2026 WL 352016 at *6 (10th Cir. Feb. 9, 2026) (noting a court’s inherent authority to sanction in the context of a brief with AI-hallucinated citations). Submitting a brief riddled with fabricated quotations and assertions is such an abuse. See Park, 91 F.4th at 615 (noting that an “attempt to persuade a court or oppose an adversary by relying on fake opinions is an abuse of the adversary system”). Counsel’s misleading the court as to the source of her errors further justifies sanctions under our inherent powers. See Ben E. Keith Co. v. Dining All., Inc., 80 F.4th 695, 703 (5th Cir. 2023) (affirming inherent-power sanctions where attorney discovered misrepresentation and failed to correct it).
We have recognized, in reviewing a district court’s sanctions order, that “an admonition by the court may be an appropriate sanction, in instances where the attorney’s sanctionable conduct was not intentional or malicious, where it constituted a first offense, and where the attorney had already recognized and apologized for his actions.” Jenkins v. Methodist Hosp. of Dallas, Inc., 478 F.3d 255, 265 (5th Cir. 2007) (reviewing Rule 11 sanctions). These factors do not counsel against sanctions here.
IT IS ORDERED that [the Attorney] shall pay $2,500 in sanctions to the United States Court of Appeals for the Fifth Circuit within 30 days of this order.”
Comment: the lawyer was fortunate to avoid a more serious sanction. We must be ever vigilant about AI and spurious citations. Note: I removed the lawyer’s name from this post.
