The scope of the maintenance of international peace and security has been increasingly widened by the United Nations Security Council in response to actions taken not only by the Member States but also in some cases by the individuals. In fact, a range of actions and decisions were taken by the Security Council, approximately in the late 1990s and after the so-called 9/11 attacks in the context of combating terrorism, as well as in other contexts against the member States. In consequence, the affected States and individuals had to seek redress from international or national courts on different grounds such as violations of human rights. This has led the domestic courts to develop novel jurisprudence. Thus, it is necessary to pay due attention to the jurisprudence created by these courts. This paper is devoted to analysis an interpretation by the High Court of Singapore in relation to sanctions resolutions of the Security Council against Iran.
