You said: Can a Utah lawyer avoid sanctions for fabricated citations by explaining that a law clerk used ChatGPT without the lawyer's knowledge? ChatGPT said: Generally, no. A Utah lawyer cannot automatically avoid sanctions for fabricated legal citations by claiming that a law clerk used ChatGPT without the lawyer's knowledge. The distinction is between responsibility for the filing and the lawyer's personal culpability. Under Utah law: Utah Rule of Civil Procedure 11: An attorney who signs or submits a court filing certifies that its legal contentions are warranted by existing law or a nonfrivolous argument for changing it, following an inquiry reasonable under the circumstances. Delegating research to a clerk does not eliminate that obligation. Utah Rule of Professional Conduct 5.3: Lawyers have supervisory responsibilities concerning nonlawyer assistants. A law clerk's unauthorized use of AI may be relevant to whether the lawyer exercised reasonable supervision, but it is not an automatic defense. Utah Rule of Professional Conduct 1.1: Lawyers must provide competent representation, including adequate legal research and preparation. Utah Rule of Professional Conduct 3.3: A lawyer who discovers that a filing contains fabricated authorities may have a duty to take reasonable remedial measures to correct the record. What would matter to the court? A judge would likely examine whether the lawyer: Established reasonable procedures for supervising the clerk. Independently checked the cited authorities before signing or filing the document. Had reason to suspect the citations were fabricated. Promptly corrected the filing after discovering the problem. Acted candidly with the court rather than attempting to shift responsibility. The lawyer's lack of knowledge may mitigate sanctions, but it does not necessarily defeat them. Rule 11 focuses substantially on the objective reasonableness of the inquiry preceding the filing, not merely whether the attorney intentionally misled the court. There is also an important procedural distinction: Utah Rule 11 contains specific requirements governing sanctions, including notice and an opportunity to respond. The availability and severity of sanctions depend on the circumstances and the authority under which sanctions are sought. Bottom line A lawyer can delegate legal research. A lawyer cannot simply delegate away professional responsibility for what gets filed. The more defensible argument is not "I didn't know my clerk used ChatGPT," but "I exercised reasonable supervision and performed a reasonable prefiling inquiry, despite which the error occurred." Even that argument depends on the evidence. One qualification: This is an analysis of the governing Utah rules, not a verified account of how a particular Utah court has ruled on this exact AI-citation defense. A specific case could turn on the judge's findings and the precise sanctions authority invoked. ChatGPT can make mistakes. Check important info. Latest response Thinking effort Instant
