%0 Journal Article %T International Peace-Keeping Operation: A Breach of International Law on Sovereignty of States? %A IO Obijiaku %J Nnamdi Azikiwe University Journal of International Law and Jurisprudence %D 2011 %I %X This article examines the legal implications of the international peace keeping operation on the sovereignty of states under International Law with insight into the meaning, origin, nature and structure of peace keeping operations. This work chronicled many peacekeeping operations already undertaken by the United Nations including the North Atlantic Treaty Organization (NATO) peace keeping operation in Yugoslavia. It further examines whether the sovereignty principle accorded every independent state in International Law had been infringed by such peace keeping operations and came to conclusion that the peace keeping operation is legally justified under Article 51 of the United Nations Charter, Selfdefence; Resolution of the United Nations and Humanitarian intervention principle among others. %U http://www.ajol.info/index.php/naujilj/article/view/82411
