- Known monetary consequence
- $1,000
Why this matter warrants attention
The court sanctioned counsel $1,000, ordered one hour of CLE on generative AI, and referred counsel to the Disciplinary Committee for filing a brief containing fabricated and misrepresented case law, in violation of Federal Rule of Civil Procedure 11(b)(2).
The court reasoned that Rule 11 requires attorneys to read and confirm the existence and validity of legal authorities. Counsel's failure to verify citations, including the use of a fabricated AI-generated case, violated the objective standard of reasonableness required by Rule 11(b)(2).
Admitting 'I didn't verify' costs $1K plus CLE plus a bar referral; verification is the minimum bar, not best practice.
