Key Details About the Database

* Focus: It tracks court and tribunal decisions where generative AI explicitly produced hallucinated content, most commonly fake legal citations, fabricated quotes, and non-existent case law.

* Scope & Size: As of October 2026, the database contains over 2,200 documented decisions globally, with U.S. federal and state courts making up the majority of the cases.
