- Observed outcome

- Known monetary consequence
- $6,000
Why this matter warrants attention
Counsel cited a nonexistent authority and later acknowledged that an AI system produced it without independent verification. The tracked outcome includes a $6,000 sanction, a bar referral, and notice to the client.
The failure involved a nonexistent case presented as authority, despite prior sanctions and training that should have made verification duties unmistakable.
Training alone is not a control. Firms need a filing gate that records who checked existence, quoted language, proposition support, and unresolved exceptions.
