International Magical Office of Law
From Harry Potter Wiki
The International Magical Office of Law keeps track of laws and policies set down by the International Confederation of Wizards, and advises Britain's Minister for Magic and the Wizengamot on matters of international law in order to prevent contradictions between British magical law and it's international counterpart. The Department of Magical Law Enforcement actually enforces the international policies and laws of the International Confederation of Wizards on British soil, albiet often relying on the advice of the International Magical Office of Law.
