Oversized Wig Theorem in International Justice: “Concepts should be in pretty general features, so they be applied to all the situations although do they not fit quite well on any of them.”
That “theorem” explains that in the field of International Law, the States´ practice is guided by the convenience of the momentum, not regarding the legal logic in the first place.

“In the antechamber of a court, a very large wig was permanently placed on a hanger behind the door, by strict order of the Court’s President. When a curious new member of the bench inquired about it, he received an explanation: The oversized wig is available to assist a colleague who forgets their own, and its considerable size allows it to fit any judge’s head, even though it does not sit well on anyone’s head.”
