This chapter examines the commission of crimes. It distinguishes between principals and accessories. It considers a range of ways of being involved in crimes, called ‘modes of participation in crimes’, such as aiding and abetting, ordering or inciting crimes, or being responsible for crimes as a superior. Further, two special doctrines of ‘commission’ have grown up before international tribunals to describe the involvement of leaders as principals in international crimes. These are called joint criminal enterprise and co-perpetration, respectively. Finally, the chapter considers what happens when the one set of facts might satisfy the elements of several different international crimes, giving rise to issues of concurrence of crimes.
