Complementarity principle

The principle of complementarity is the basis of the relationship between the International Criminal Court and national courts in relation to the application of international criminal law. It means that the ICC has secondary jurisdiction after national courts, and can only act in a given situation if the relevant states are unwilling or unable to prosecute the crimes within their jurisdiction.
