of the bar of this Court to “comply with the standards of professional conduct required of members of the State Bar of California.” Civil L.R. 11-4(a)(1). Under California Rule of Professional Conduct 3.3, lawyers have a duty of candor, which prohibits a lawyer from “knowingly mak[ing] a false statement of fact or law to a tribunal[.]” On this record, the Court is concerned that Mr. Nguy’s counsel may have relied on AI to identify legal authorities and did not exercise care in ensuring that that fictitious AI-generated legal authorities were not included in Mr. Nguy’s opposition filed with the Court.
