Why this matter is tracked
Misrepresented: Case Law | McDonald cited In re Estate of McCreath to claim the trustee’s duty of impartiality cannot be overridden by trust terms; the court noted the case does not address that duty and does not support the proposition. Outcome: Warning. The court noted that:"both Lehr-Guthrie's and McDonald's briefs are replete with errors in their citations to case authority, such as repeated citation errors, references to nonexistent quotes, and incorrect statements about the cases (for instance, as noted above, the two cases McDonald cited for a proposition relating to the duty of impartiality don't even reference that duty). This suggests to us that the briefs may have been drafted with the use of generative artificial intelligence (GAI). “[U]sing a GAI tool to draft a legal document can pose serious risks if the user does not thoroughly review the tool's output.” Al-Hamim v. Star Hearthstone, LLC, 2024 COA 128, ¶ 32. Self-represented litigants must be particularly careful, as they “may not understand that a GAI tool may confidently respond to a query regarding a legal topic ‘even if the answer contains errors, hallucinations, falsehoods, or biases.’ ” Id. (citation omitted).4 We advise the parties that errors caused by GAI in future filings may result in sanctions. See id. at ¶ 41. "The court warned that future errors caused by AI could result in sanctions.
