Together with the Security Council and the General Assembly, the International Court of Justice is one of the most important guarantors of peace, security and co-operation among states. The role of the ICJ in the enforcement of its decisions has received little attention in the existing literature. Although international courts, regional courts and national courts do not physically enforce their decisions, they have various levels of enforcement mechanism procedures. Nevertheless, it has been widely and mistakenly believed that it is not the business of the ICJ to enforce its decisions, but rather this is the business of other political bodies of the United Nations. It is argued in this paper that this proposition is not accurate and, instead, the ICJ has at its disposal various enforcement procedures and is, moreover, under statutory obligations to participate actively in policing and enforcing its decisions.
