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

Summary

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.
