Incident 16822 Rapports
D.C. Court of Appeals Struck Deutsche Bank National Trust Company Brief After Attorney Used Google Generative AI Search Tool and Filed Four Nonexistent Case Citations

2025-08-12

In Douglas v. Deutsche Bank National Trust Co., attorney Loishirl W. Hall acknowledged using Google's generative AI search tool to locate case authority and failing to verify citations before an appellate brief was filed. The D.C. Court of Appeals found four cited cases did not exist, said the filing misdirected the court and burdened judicial resources, struck Deutsche Bank's brief, and referred the matter for disciplinary review.

Incident 15721 Rapport
Westlaw CoCounsel Reportedly Generated False Legal Quotations in United States v. Farris

2025-10-21

In United States v. Farris, court-appointed attorney Steven N. Howe admitted using Westlaw CoCounsel to draft appellate briefs that reportedly included AI-generated false quotations and misleading descriptions of precedent. The filing disrupted Farris's appeal, leading the court to appoint new counsel and restart briefing, while Howe lost his compensation and faced possible disciplinary action.
