  • What is international law?

    Question:
    What is the principle of state sovereignty in international law?

    Answer:

    The principle of state sovereignty means that each state has full authority and independence over its territory and domestic affairs, free from external interference by other states. This principle is a fundamental concept in international law and is recognized in the United Nations Charter. However, sovereignty is not absolutestates are still bound by international treaties, customary international law, and obligations such as respecting human rights and maintaining international peace and security.
