Abstract
LL.M. (International Law)
The coming into force of the Rome Statute of the ICC (International Criminal Court) created a shift in state attitude in respect of the implementation and enforcement of International Law. In particular, several issues arise concerning the role to be played by states in the context of complementarity between the ICC and national courts. The ICC has jurisdiction over crimes of the most concern to the international community and its power is limited by, amongst others, the complementarity principle as well as the jurisdiction and functioning of national courts.
States parties agreed to establish a permanent court which would put an end to impunity and prevent acts of core international crimes, as well as ensure effective prosecution of international crimes. Under the Rome Statute, states parties are obliged to develop measures at the national level in order to enhance international cooperation with the ICC. The complementarity principle encompasses, amongst others, the duty of every State to exercise criminal jurisdiction over international crimes, to enhance the capacity of national jurisdiction and to implement an appropriate national legal system which provides the same level of guarantee in investigating and prosecuting international crimes as the ICC. Both the ICC and national courts have jurisdiction over core crimes and this concurrent jurisdiction causes conflict between both institutions. The complementarity principle is based on the basis that states should maintain primary responsibility to protect their populations from genocide, war crimes, and crimes against humanity. However,these conflicts do not arise with Ad Hoc tribunals, whose Statutes emphasise the supremacy of the international criminal tribunals over national courts.
The complementarity principle is based on the basis that states should maintain primary responsibility to protect their populations from genocide, war crimes, and crimes against humanity.
The complementarity principle provides that prosecutions of crimes stipulated under the Rome Statute are primarily the task of states and the ICC is the court of last resort.6 This primary competence of national courts and the boundary between the two jurisdictions is given expression in article 17 of the Rome Statute. Prosecutions of core crimes before the ICC are only admissible if, and under condition that, an effective prosecution at the national level is threatened by legal, political and factual obstacles.
