Department of Magical Law Enforcement
The largest Ministry department - police, courts, and regulatory authority for wizarding Britain
Overview
The Department of Magical Law Enforcement (D.M.L.E.) is the largest and most powerful department within the Ministry of Magic. Operating from Level 2, it serves as the wizarding world's combined police force, court system, and regulatory body.
