These would be states whose nationals had been punished abroad or states on whose territory the offence had been committed or against which the offence was directed, where the offender had been acquitted or condemned in another country. In the bulk of cases this will be quite sufficient to ensure both just punishment of offenders and the objective and largely uniform judicial assessment of offences. For some cases, such as genocide, additional legal remedies will perhaps have to be created since no other state need be directly affected by the crime. But acceptable solutions can undoubtedly be found to these problems once there is a decision in principle for a combination of universal criminal jurisdiction and an international criminal court. Similarly, details such as the staffing of an international criminal court and other questions could be left to a later stage of discussion.
Experience shows that they cause the least difficulties.
Moreover, there is a great deal of serious preliminary work on this to which recourse can be had. If universal criminal jurisdiction is combined with an international criminal court, an international prosecutorial department need not be set up. States involved will appear as prosecutors. It may be assumed that they will only prosecute cases in which they have a serious interest. Thus, the court would not be encumbered with an onslaught of cases.
