The lecture, which pre-dates the 2010 Kampala Review Conference, focuses on the outreach of the Security Council in the area of individual criminal responsibility, more particularly on its relationship with the International Criminal Court. This linkage between criminal justice and the restoration and maintenance of international peace and security, which is sustained both by the Statute of the ICC and the practice of the Security Council, cannot be seen in isolation. It raises important systemic issues for it must be analyzed within the context of an emerging ordre public of the international community, as well in the light of the classical debate over the legal/political dichotomy in international society and the separation of political from judicial organ. The interlocking of collective security mechanisms with the hybrid process of institutionalization of international criminal responsibility underlines the problem of developing international law through a process that includes the ad hoc and piecemeal reactions of a political organ to particular crises.
