The Department of Magical Law Enforcement is the largest department at the Ministry of Magic. Arguably the most important of the various departments, it is a combination of police and justice facilities, and is roughly the equivalent to the Home Office of Muggle Britain or the Department of Justice in the United States. It includes the following known departments:
The Aurors' Office, Misuse of Muggle Artifacts Office, Wizengamot Administration Services, Improper Use of Magic Office, and Office for the Detection and Confiscation of Counterfeit Defensive Spells and Protective Objects. Here is where all the discussion of rules and justice will take place.
