<![CDATA[War crimes are one of the serious violations of international humanitarian law that still raise the issue of impunity for the perpetrators. The presence of the 1998 Rome Statute and the International Criminal Court (ICC) is an effort by the international community to realize criminal accountability for war crimes perpetrators through a permanent international justice mechanism. This study aims to analyze the regulation of war crimes law enforcement based on the 1998 Rome Statute, assess the effectiveness of the ICC in preventing impunity, and examine the conflict of norms that are obstacles in its implementation. This study uses normative legal research methods with a statute approach, a case approach, and a conceptual approach. The legal materials used include the 1998 Rome Statute, the Charter of the United Nations, the 1949 Geneva Conventions, the judgments of the International Criminal Court, as well as various relevant legal literature. The results of the study show that the 1998 Rome Statute has provided a comprehensive legal basis through the principle of complementarity that places national jurisdiction as the main forum, while the ICC plays a complementary role when the state is unable or unwilling to prosecute war criminals. However, the effectiveness of the ICC in preventing impunity is still not optimal because the exercise of its authority depends on state cooperation. In addition, the conflict of norms between the principle of complementarity and state sovereignty, the jurisdiction of the ICC with the veto power of the United Nations Security Council, and the obligation to surrender suspects with the doctrine of immunity of the head of state are the main obstacles in the enforcement of international criminal law. Therefore, it is necessary to strengthen the country's commitment to the Rome Statute, increase international cooperation, and harmonize international legal norms so that the goal of ending impunity for war criminals can be realized more effectively.]]>
