In a development that highlights ongoing challenges in the integration of artificial intelligence within legal practices, two recent cases have surfaced where lawyers faced disciplinary actions for submitting briefs with fabricated legal citations generated by AI tools. The cases are reminiscent of an increasing trend where the reliance on AI technology has led legal professionals into disputable circumstances.
The first instance unfolded in the U.S. District Court for the Central District of California. Attorneys from the law firms Ellis George LLP and K&L Gates LLP submitted a brief containing multiple non-existent citations. These errors stemmed from AI tools—which included CoCounsel, Westlaw Precision, and Google Gemini—used to draft the brief. Trent Copeland, representing Ellis George, admitted to using these tools without adequately verifying the outputs or informing his colleagues about its AI origins, leading to the ill-advised submission of the erroneous brief. K&L Gates also bore criticism for failing to verify the citations in the subsequent ‘corrected’ version of the brief. As a repercussion, the special master imposed sanctions which included striking the brief, denying discovery relief, and obligating the involved firms to pay $31,100 in legal fees to the defendant. The firms were also mandated to disclose the incident to their client.
In a parallel case in Canada, lawyer Jisuh Lee was scrutinized by Judge Fred Myers of the Ontario Superior Court. The factum she presented in the matter of Ko v. Li included references to non-existent cases, further complicated by a citation of a case misrepresenting its legal principle. Judge Myers observed that her submission showcased a possible lack of due diligence in cross-verifying precedential authorities suggested by AI.
These episodes underscore the critical need for thorough verification of AI-generated legal research outputs. Despite mounting judicial warnings and professional guidance from bar associations reaffirming the importance of traditional legal research practices, the lapses continue to prompt disciplinary actions against attorneys. The reliance on AI without appropriate checks intensifies the risk of errors, significantly impacting litigative outcomes.
