Appellate Court Imposes Sanctions For AI-Fabricated Citations
On Jan. 8, New York's intermediate appellate court in Deutsche Bank Nat'l Trust Co. v. LeTennier found defense filings contained at least 23 fabricated cases and concluded counsel used generative AI without adequate oversight. The court imposed $5,000 plus an additional $2,500 sanction on counsel and $2,500 on the defendant, totaling $10,000, and emphasized attorneys must fact-check AI-assisted submissions. The decision establishes appellate-level deterrence against AI-driven frivolous filings.
Key Points
- 1Finds 23 fabricated cases across five filings tied to counsel's generative AI use.
- 2Highlights risk that unvetted generative AI produces fabricated authorities, undermining legal accuracy and candor.
- 3Requires attorneys to rigorously fact- and cite-check AI-assisted filings or face monetary sanctions.
Scoring Rationale
Authoritative, precedent-setting court ruling on GenAI misuse; primarily confined to legal-practice implications rather than broader AI sectors.
