The Larger Cost of Reckless GAI Use in Litigation

Jeanne M Huey

Summary

  • In Gauthier v. Goodyear Tire & Rubber Co., a lawyer was sanctioned for submitting unverified GAI-generated content (two citations to entirely fabricated cases and nonexistent quotations from seven actual cases) in a response to a motion for summary judgment.
  • The Gauthier court found that the lawyer violated Federal Rule of Civil Procedure 11, as well as local rules regarding candor/diligence and verification of computer-generated content. If lawyers continue to disregard Rule 11, courts may impose stricter measures.
  • In Gauthier, the opposing counsel spent significant time and resources to check the citations/quotes in the response and inform the court. Courts don’t always directly compensate opposing counsel for fees incurred by the other side's careless use of GAI.
  • GAI incompetence implicates Model Rules regarding technological competence and ethical issues. Lawyers who disregard the risks of relying on unverified GAI-generated content not only face serious professional repercussions but also undermine the integrity of the justice system.

Courts, opposing parties, and clients all suffer when lawyers fail to properly vet work generated by artificial intelligence (“AI”), leading to wasted judicial resources, procedural delays, and broken client and public trust.

Gauthier: GAI Hallucinations in Court Filings

A recent case serves as a stark reminder that competence and diligence in using generative AI (“GAI”) tools is not optional but is an ethical imperative.

In Gauthier v. Goodyear Tire & Rubber Co., a lawyer was sanctioned for submitting unverified GAI-generated content in a response to a motion for summary judgment. No. 1:23-CV-281 (E.D. Tex. Nov. 25, 2024). This included two citations to entirely fabricated cases and nonexistent quotations from seven actual cases—that is, “hallucinations.”

In sanctioning the lawyer, the court determined that the lawyer submitted a false statement of law to the court and failed to rectify the mistake after opposing counsel pointed it out in their reply. Instead, the lawyer did not address the error until the court issued a show-cause order. The court also remarked that “it is unclear what legal research, if any,” the lawyer conducted before filing the response. Id. at *5.

The lawyer was ordered to pay $2,000 into the court registry, to take one hour of CLE on the topic of GAI in the legal field, and to provide his client with a copy of the sanctions order. The sanctions imposed were relatively mild considering the potential harm to the client, the opposing party, and the integrity of the court system.

Wasted Resources and Judicial Frustration

GAI-generated errors like those in Gauthier force courts to spend time unraveling the problem rather than addressing the substantive legal issues. That’s why courts increasingly impose strict requirements in their local rules regarding GAI use.

In addition to finding that the lawyer violated Federal Rule of Civil Procedure 11, the Gauthier court found violations of its local rules requiring lawyers to exercise candor and diligence and mandating that lawyers review and verify any computer-generated content before submitting it.

Moreover, the court likely could have found a violation of ABA Model Rule 3.3 pertaining to candor to the tribunal, and ABA Model Rule 8.4(c) and (d) for engaging in conduct “involving dishonesty, fraud, deceit or misrepresentation” and that is “prejudicial to the administration of justice.” The lawyer also could have been referred to the local disciplinary authority by the court, opposing counsel, opposing party, or client.

Rule 11 already provides a framework for addressing these concerns, but if lawyers continue to disregard it, courts may impose stricter measures. Lead counsel might be required to certify or swear to the accuracy of every filing—something their signature should already indicate. Courts could mandate CLE credits on AI use as a condition for good standing or pro hac vice admission. Additional burdens may include requiring attorneys to keep records of all GAI-generated prompts used in preparing the filing or to attach every cited case as an appendix with key holdings and quotations highlighted. Courts might also implement prefiling review requirements, mandating independent verification of AI-generated content before docketing.

Unnecessary Burdens and Expenses for Opposing Parties

In Gauthier, the opposing counsel said that they had spent significant time and resources—over $7,500 in fees—determining that the citations and quotes in the response were fictitious and bringing the issue to the court’s attention. However, lawyers who use GAI irresponsibly do not simply create wasted work for their adversaries. An offending lawyer almost certainly violates their ethical obligations under ABA Model Rule 3.1, which prohibits lawyers from bringing or defending claims that lack a legal or factual basis, ABA Model Rule 3.2, which requires lawyers to make reasonable efforts to expedite litigation, and ABA Model Rule 3.4, which mandates fairness to opposing parties by prohibiting conduct that delays or burdens litigation without substantial justification.

Although courts may not always directly compensate opposing counsel for fees incurred by the other side's careless use of GAI—the Gauthier court did not—judges are not blind to the larger impact of such conduct. If GAI-related errors continue to occur, lawyers can expect (and should ask) courts to shift the burden of these costs onto the offending lawyers through harsher sanctions and fee-shifting orders.

Sanctions and Eroded Client Trust

The most direct impact of GAI incompetence is on the lawyer-client relationship. In Gauthier, the court ordered that the sanctions order be provided to the lawyer’s client so that the client would know that his lawyer had been sanctioned for submitting false information to the court.

Beyond the immediate embarrassment and potential financial consequences to the lawyer, basic competence is at play. ABA Model Rule 1.1 Comment 8 requires lawyers to maintain competence in the technology that they are using in their practice, including understanding the technology’s benefits and risks. A lawyer who does not understand how GAI functions or fails to verify GAI-generated work has not met this duty of competence. While clients expect lawyers to be efficient and cost-effective and may think that using GAI will help reduce legal fees, they do not pay lawyers to take risks with their case outcomes; they certainly don’t pay for them to misrepresent the law and be embarrassed in front of a judge. A single GAI-related error could permanently undermine clients’ faith in their attorney and end the representation.

The Public’s Perception: Lawyers Need to Control the Narrative

Currently, the public is receiving two conflicting messages about GAI:

  • "GAI will replace lawyers."
  • "Lawyers are getting sanctioned because they do not know how to use GAI."    

Neither narrative is good for the profession. Clients will resist paying for legal expertise if GAI is considered an inevitable replacement. Public confidence in the legal system will erode if lawyers can’t be trusted to understand and use GAI correctly.

The only way to control this perception is through responsible behavior, professionalism, and a commitment to meeting and exceeding our ethical duties under the rules when we use GIA and related technology. It will also be necessary to effectively communicate with clients about GAI and how it might be used within the firm, such as in billing software, or in their case, which may require their informed consent.

Ethics opinions and court rules concerning GAI differ across jurisdictions, and the applicable standards of care are evolving rapidly. Staying current and ethically integrating GAI tools into our law practices will take time and attention. Those who fail to do so risk not just sanctions but harm to both their professional reputation and the credibility of the legal system: lawyers who understand the risks and benefits of GAI and implement its use responsibly will not only protect their practice but also strengthen public trust in the profession and help shape its future.
