Part 2 Attributing Criminal Responsibility, 5 Principals and Accessories
This chapter discusses principal and accessorial liability in international criminal law. It analyzes participation models in international criminal law through the lens of the approaches discerned in the previous chapter. When discussing the distinction between principals and accessories in international criminal law, it becomes clear that the normative approach to criminal participation has gained ground in recent years. For that reason, the chapter elaborates on the distinguishing criterion in a normative model of participation, which means answering the question who is ‘most responsible’. Different theories have been developed in national criminal law to answer that question. One such theory is Roxin's theory of Tatherrschaft. This theory warrants analysis since it has been influential in international criminal law, particularly at the International Criminal Court (ICC). It is attuned to system criminality and lies at the basis of the ‘control of the crime’ theory adopted at the ICC.
