The Crime of Aggression as Custom and the Mechanisms for Determining Acts of Aggression
The fallout from the 2010 Kampala Review Conference for the United States has been explained by Harold Koh and Todd Buchwald, who were officially involved in the negotiations at the conference. The concerns they enumerate serve to implicate, inter alia, two issues of broad importance for the international community: the definition of the crime of aggression, and the clear divide between the positions of the permanent members of the UN Security Council and the rest of the Kampala participants with respect to the Councils role in implementing the Rome Statute’s new provisions on the crime of aggression. This Note, which focuses on those two issues, is partly a response to some of their criticisms and partly an independent assessment of the consequences of the Review Conference. It also evaluates the Kampala amendments to the Rome Statute’in particular, Articles 8 bis, 15 bis, and 15 ter—from the perspective of customary law and considers their impact on the role assigned to the Council under the UN Charter.
