You could view the Accords as a sort of mutual protection pact… rather like the United Nations, really. If nation A does damage to nation B, then nations C, D, E and F will come down on A like a ton of bricks. Areas like ANG’s like the pub provide a place for ambassadors to meet and talk out issues without a fight breaking out. It ensures a chance for communication to prevent war.
There is no ‘spirit’ of the accords, just the letter, because… well mainly because Fae are involved and they don’t “get” the idea of there being a ‘spirit’ of an agreement. For them there is only the letter of the law and to prevent mishaps, no other members can do it any other way.
