Just as much of a violation of sovereignty as the ICC  Part of the calls for an African Criminal Court are based on the perception that the national sovereignty of African nations is being attacked in some way before the International Criminal Court.  However, an African Criminal Court would be just as much of a violation of the sovereignty of individual African nations as the ICC; it is a system of courts outside the control of the nation of those it is trying.  European states object to courts outside their control dictating even when they are regional courts – consider the reactions to the European Court of Human Rights on areas like voting for prisoners or to the European Court of Justice. That these are regional not global courts makes little difference to national opinion. It is no surprise then that not even the EU with its close relations has attempted a supra national criminal court system.
