Why this matter warrants attention
The court sanctioned counsel for Rule 11 violations involving the submission of at least 18 fabricated case citations and false quotations. Sanctions include an order to pay the defendant's reasonable attorneys' fees, mandatory completion of a CLE course on AI ethics, and notification of the disciplinary order to relevant state bars and the district's bench.
The court reasoned that counsel's repeated submission of fictitious citations and quotations, which bore the characteristics of AI-hallucinated content, violated Rule 11(b)(2). The court rejected counsel's 'clerical error' and 'law clerk' defenses as implausible, noting that counsel failed to perform a reasonable and competent inquiry into the existence of the cited authorities. The court emphasized that an attorney's duty of candor and verification cannot be delegated to subordinates or automated tools.
Mandatory CLE plus costs attaches once fabricated citations appear across multiple filings — one audit would catch the pattern.
