In this chapter, James Mehigan focuses on the contribution of international criminal law (ICL) to the peaceful settlement of international disputes. More specifically, this chapter looks at the aims of ICL and analyses how effective it has been at achieving its international law and criminal law objectives. It argues that ICL does not make the broader contribution to dispute settlement that many commentators hope for because it provides a form of retributive justice that does not necessarily engender a sense of justice for victims, nor contribute to reconciliation or fact-finding. After looking at the impact of ICL in the Former Yugoslavia, this chapter concludes that there is little evidence to show that ICL achieves any of its aims other than individualising guilt and punishing offenders – in other words, ICL’s contribution to the settlement of international disputes is minimal and should not be overstated.
