sovereignty

Sovereignty is generally defined as supreme, independent control and lawmaking authority over a territory. It is expressed through the power to rule and make law. Sovereignty entails hierarchy within a state as well as external autonomy, which refers to the ability of a state to act independently in international affairs. In any state, sovereignty is assigned to the person, body or institution that has the ultimate authority over its citizens and the power to modify existing laws. In political theory, sovereignty is a substantive term designating supreme legitimate authority over some polity. According to international law, sovereign states are all considered equal, and no state has the right to interfere in the internal affairs of another sovereign state. While Article 2(7) of the UN Charter explicitly recognizes the sovereignty of states, and in general there is a principle of non-interference in the domestic affairs of sovereign states, the UN Security Council’s Chapter VII powers clearly contemplate the use of force against a state when necessary to restore peace. Moreover, the recent Responsibility to Protect (R2P) authorizes the United Nations to take action to “avert a humanitarian catastrophe” within a state when that state's government cannot or will not act.
