Since the creation of special courts to address the issues of war crimes after World War II there have been a series of other courts created to handle particular issues of international concern. The following is a list of the most prominent of those courts.

“The International Criminal Court (ICC) is an independent, permanent court that tries persons accused of the most serious crimes of international concern, namely genocide, crimes against humanity and war crimes. The ICC is based on a treaty, joined by 124 countries.
The ICC is a court of last resort. It will not act if a case is investigated or prosecuted by a national judicial system unless the national proceedings are not genuine, for example if formal proceedings were undertaken solely to shield a person from criminal responsibility. In addition, the ICC only tries those accused of the gravest crimes.
In all of its activities, the ICC observes the highest standards of fairness and due process. The jurisdiction and functioning of the ICC are governed by the Rome Statute.” (Source: ICC)
