As shown by the recent trials of Slobodan Milosevic, Charles Taylor and Saddam Hussein, the large-scale and systematic commission of international crimes is usually planned and set in motion by senior political and military leaders. Nevertheless, the application of traditional forms of criminal liability leads to the conclusion that they are mere accessories to such crimes.
This does not reflect their central role and often results in a punishment which is inappropriately low in view of the impact of their actions and omissions. For these reasons, international criminal law has placed special emphasis on the development the concepts of joint criminal enterprise (also known as the common purpose doctrine) and control of the crime, which aim at reflecting better the central role played by senior political and military leaders in campaigns of large scale and systematic commission of international crimes.
The Rome Statute of the International Criminal Court and the case law of the ICTY and the ICTR have, in recent years, played a unique role in the achievement of this goal.
