The Goblin Liaison Office is part of the Being Division of the Department for the Regulation and Control of Magical Creatures. It is the section which takes care of the magic economy and the relations between goblins and wizards. Cuthbert Mockridge headed the Office in 1994, but shortly after he was replaced by Dirk Cresswell. It appears to be a highly respected field, and the head of the office is a highly regarded post.
