Once again, a lawyer has used generative AI to draft a brief, with embarrassing consequences. In Mid-Central Operating Engineers Health and Welfare Fund v. Hoosiervac, LLC SD Indiana 2025, the 2:24-cv-00326, a lawyer got into trouble for using Generative AI to draft a brief. The court that Rule 11 was violated and that there were violations of the Indiana Rules of Professional Conduct.
On October 29, 2024, attorney Ramirez filed a brief in support of Defendant’s Motion to Reconsider the Court’s Denial of Motion to Transfer. [Dkt. 65.] In that brief, Mr. Ramirez cited to In re Cook County Treasurer, 773 F.3d 834 (7th Cir. 2014)—a case the Undersigned was unable to locate. In response to the Undersigned’s Order to file a Notice with the correct citation, [Dkt. 82], Mr. Ramirez filed a Notice in which he stated that he was unable to locate the case, “acknowledge[d] that the referenced citation was in error,” “withdr[ew] the previously cited authority[,] and apologize[d] to the Court and opposing counsel for the confusion.” [Dkt. 86 at 1.]
On December 23, 2024, the Undersigned explained that “filing a brief with a non-existent citation falls far short of an attorney’s duty to the Court, his client, and opposing counsel.” [Dkt. 87.] Accordingly, pursuant to Federal Rule of Civil Procedure 11(c)(3), the Undersigned ordered Mr. Ramirez to appear in-person and show cause why he should not be sanctioned for violating Federal Rule of Civil Procedure 11(b). Id. In that Order, the Undersigned noted that a non-exhaustive review of Mr. Ramirez’s other filings in this case revealed citations in two other briefs that the Undersigned was unable to locate: Knoedler Manufactuers, Inc. v. Cox, 545 F.2d 1033, 1035 (7th Cir. 1976), cited in [Dkt. 39]; and Brown v. Local 58, IBEW, 628 F.2d 441 (6th Cir. 1980), cited in [Dkt. 52].
On January 3, 2025, the parties in this matter appeared by counsel for a hearing on the Order to Show Cause. [Dkt. 88.] Mr. Ramirez admitted that he had relied on programs utilizing generative artificial intelligence (“AI”) to draft the briefs. Mr. Ramirez explained that he had used AI before to assist with legal matters, such as drafting agreements, and did not know that AI was capable of generating fictitious cases and citations. These “hallucination cites,” Mr. Ramirez asserted, included text excerpts which appeared to be credible. As such, Mr. Ramirez did not conduct any further research, nor did he make any attempt to verify the existence of the generated citations. Mr. Ramirez reported that he has since taken continuing legal education courses on the topic of AI use and continues to use AI products which he has been assured will not produce “hallucination cites.” Mr. Ramirez agreed during the hearing that he did not fully comply with Rule 11, but he emphasized that at no point did he act in bad faith or proceed with malice.
The court recommended a sanction of $15,000, one for each of the briefs with fake citations.
The court also found three violations of the Indiana Rules of Professional Conduct.
At least three of the Indiana Rules of Professional Conduct are implicated here, and the Undersigned will address them each in turn.
A. Rule 1.1. Competence
“A lawyer shall provide competent representation to a client. Competent representation requires the legal knowledge, skill, thoroughness and preparation reasonably necessary for the representation.” Ind. R. of Prof. Conduct 1.1. It is clear that Mr. Ramirez failed to provide competent representation when he submitted false legal bases to the Court. These actions flouted the requisite legal knowledge, skill, preparation, and especially thoroughness reasonably necessary for Mr. Ramirez’s representation of his client.
B. Rule 3.1. Meritorious Claims and Contentions
“A lawyer shall not bring or defend a proceeding, or assert or controvert an issue therein, unless there is a basis in law and fact for doing so that is not frivolous, which includes a good faith argument for an extension, modification or reversal of existing law.” Ind. R. of Prof. Conduct 3.1. This Rule mirrors the requirements of Rule 11(b)(2), and likewise proscribes presenting unfounded legal bases. There is no merit in relying on non-existent cases, so Mr. Ramirez’s conduct clearly disregards this Rule.
C. Rule 3.3. Candor Toward the Tribunal
“A lawyer shall not knowingly: . . . make a false statement of fact or law to a tribunal or fail to correct a false statement of material fact or law previously made to the tribunal by the lawyer.” Ind. R. of Prof. Conduct 3.3(a)(1). It is undisputed that Mr. Ramirez made false statements of law to the Court when in three separate submissions he relied on at least three cases which do not exist. Moreover, Mr. Ramirez did so “knowingly”—he knowingly failed to fulfill his duty of verifying that the law he presented was “good law.” As such, the Undersigned believes that discipline for violation of Indiana Rule of Professional Conduct 3.3 is appropriate as well.
Conclusions: (a) Do your own work; (b) don’t use generative AI to draft briefs because it can hallucinate; (c) even if you use AI, make sure to check the end product against real cases.
