Sovereignty is a word that is often used wrongly. Lassa Oppenheim said that there is no idea whose meaning is more than sovereignty. No one argues the fact that from the time the idea of sovereignty was first used in political science until now, there has never been one meaning that everyone agreed on. Justice Evatt of the High Court of Australia says that "sovereignty is neither a question of fact, nor a question of law, but a question that does not arise at all."
