A Georgia judge sanctioned attorney Tristan Gillespie $25,000 over AI-hallucinated cases

A Georgia judge imposed a $25,000 financial sanction on plaintiff's attorney Tristan S. Gillespie after finding his court filings contained multiple case citations fabricated by ChatGPT. Defense attorney Luke Kennedy of McMickle, Kurey & Branch moved for sanctions after discovering at least eight faulty citations across four filings, including non-existent cases such as Kaplan v. Banks and Cox v. Webb. The court characterized the sanction as warranted under Rule 11 and its inherent authority, emphasizing that filing unverified AI-generated legal authority constitutes sanctionable misconduct.
