The emergence of International Criminal Court had been a welcome development owning to its contribution to the protection of minorities, children and unarmed citizens during armed conflict. The importance of International Criminal Court cannot be overemphasized owing to the fact that the peace and security of the human race depends on this court. Owing to the excessive importance of protecting human rights the International Criminal Court has been mandated to ensure its enforcements. It will be noted that the International Criminal Court is not a domestic court but an Intergovernmental and International court which sits in The Hague, Netherlands. The International Criminal Court is designed to complement the existing national judicial structure as it prosecutes states as well as individuals for international crimes. However this paper seeks to examine the complementary nature of the International Criminal Court, the role of the Security Council of the United Nations in prosecuting international crimes and the methods of evaluating the proper functioning of International Criminal Court. This paper will hereby suggest the review of international personality and the review of sanctions for disobeying the court's order.
