안보리 대북제재 결의의 국내 수용과 해상차단의 헌법적 정당성

Since 2006, the United Nations Security Council sanctions regime against North Korea has been progressively strengthened. In particular, following Resolution 1874, maritime interdiction measures, including the inspection of vessels on the high seas, orders to proceed to port, and the seizure and disposal of prohibited items, have emerged as a central means of sanctions implementation. Because such measures go beyond mere diplomatic cooperation or administrative assistance and constitute coercive exercises of public authority that may substantially affect the movement of vessels, the disposition of cargo, proprietary interests, and, in some cases, even personal liberty and bodily freedom, their domestic implementation must be examined not only as a matter of international law but also as a constitutional issue. However, Security Council resolutions are not treaty-based norms, and it is not clear whether they fall within the category of “generally accepted rules of international law” under Article 6(1) of the Constitution of the Republic of Korea. Accordingly, apart from the international legal binding force of Security Council resolutions, constitutional questions arise as to how such obligations are to be incorporated domestically and to what extent they may confer authority upon domestic enforcement agencies. This study examines, first, the binding force of Security Council sanctions resolutions and the requirements of a “decision” under Chapter VII of the United Nations Charter and Article 25, and analyzes the legal character of maritime sanctions measures against North Korea and the scope of obligations imposed on Member States by considering the wording of the resolutions, their context of adoption, and the Charter provisions invoked. It then explores, within the constitutional order of the Republic of Korea, the framework for reviewing the constitutional legitimacy of domestic implementation through the structure for the reception of treaties and rules of international law, the role of the National Assembly, the principle of statutory reservation, the limits of delegated legislation, and the standards governing restrictions on fundamental rights and due process. It further examines the current domestic implementation system and the legal and operational framework relating to maritime interdiction, in order to assess whether the existing system provides a direct and integrated legal basis for measures such as inspection, diversion, detention, and seizure, and whether it secures sufficient clarity, democratic control, and remedies. In addition, by reviewing the legislative models of the United States, Japan, and the European Union, together with domestic legislative proposals, it comparatively evaluates the methods by which obligations under Security Council resolutions are translated into domestic enforcement powers and procedures, as well as the constitutional safeguards required in that process. Security Council sanctions resolutions against North Korea may impose obligations on Member States as a matter of international law, but such obligations do not automatically translate into direct authorization for domestic enforcement agencies. The current domestic implementation system in Korea, which relies on a combination of function-specific statutes and administrative regulations, likewise remains structurally insufficient to justify highly coercive measures such as maritime interdiction. Accordingly, there is a need to develop a Korean legislative framework for the implementation of Security Council resolutions that can preserve both the promptness and fidelity required by international law while simultaneously ensuring statutory reservation, separation of powers, due process, democratic control, and remedies.
