Enies Lobby, also known as The Judicial Island (司法の島 Shihō no Shima?), was a government-controlled stronghold in Paradise together with the Marine Headquarters and Impel Down, and the headquarters of CP9. Enies Lobby is located on an island referred to as both the "afternoon island" (昼島 hiru-jima?) and the "never-night island" (不夜島 fuya-jima?).

Enies Lobby led to Impel Down and the Marine Headquarters directly.[2] Because of this, there were many government agents stationed there, roughly 10,000 men, a mix of those from both the World Government and the Marines. The island also had a courthouse, which made it easy to transfer high-level criminals through Enies Lobby and directly into Impel Down, or to the Marine HQ.
