The jurisdiction of the International Criminal Court (hereinafter: ICC) is limited to the most serious crimes of concern to the entire international community that threaten security, peace, and well-being of the world. This article argues that serious (transitional) economic offences should belong in this group. Ignoring these crimes, which often represent economic violence characteristic of transitional and post-conflict countries, can lead to another cycle of armed conflict and/or physical violence as well as to internal and external insecurity. Responses to globalization are having a significant effect on international law and institutions with a view to protecting economic and social human rights, human security, and human dignity. Sometimes, as in the case of Croatia, national states are not able to and/or unwilling to prosecute serious and systemic economic crimes, which in turn undermines individual and collective security. The same could be said for international criminal law. By ignoring these crimes and violations – unlike what international human rights law, supranational criminology, and transitional justice does – the core international criminal law no longer responds to the needs of societies and individuals. The Rechtsgut in need of protection by prosecuting serious economic crimes that fulfill the threshold of core crimes on an international level is comprised of the “security, peace and well-being of the world.” Therefore, one could argue that the International Criminal Court’s possible involvement in economic violence does have a legal base, without needing to amend the ICC’s Statute (hereinafter: ICCSt). Since one must be aware of the diversity that exists as to the criteria for international criminalization, this article is based on broader grounds in order to argue in favor of international criminalization of these economic crimes. The article therefore emphasizes the importance of connecting narratives of international criminal law, with discourses on international human rights law (based on Art. 21 of the ICCSt), human security, (supranational) criminology, transitional justice, and (economic) criminal law. In the line of (human) security discourse, this approach seeks to find arguments as to whether or not it is necessary to begin prosecuting serious (transitional) economic offences as crimes under international law. First, this article gives a brief overview of the failed experiment in Croatia concerning the prosecution of transitional economic crimes that served as incentive, based on the ICC’s complementarity principle.
