In his excellent essay, James Stewart advocates for a unitary model of perpetration. To the extent that this means the end of modes of liability, so be it says Stewart. We don’t need them. They codify distinctions that we don’t need, promote confusion over coherence, and so we should instead streamline the centrifugal doctrines into a single account of causal contribution. On the elegance scale, Stewart’s proposal should score a 10 from most judges.
Stewart pitches his account as revisionary, an attempt to right the ship after years of confusing scholarly and judicial debate about modes of liability and the difference between principals and accessories (or other categories that occupy similar conceptual space). But I think that it is the wrong light in which to see the argument.
I see Stewart’s proposal as urging return to a substantially similar state of affairs under the original Joint Criminal Enterprise scheme proposed by the
Tadic Appeals Chamber during the early days of the ICTY. Cassese was the prime mover behind the JCE doctrine, and it covered all members of the collective endeavor, regardless of their level of contribution. Eventually, the doctrine was modified to require a heightened contribution requirement, and eventually the leadership level defendants were “de-linked” from the foot soldiers and placed in separate JCEs. But the important point is that the original JCE doctrine included everyone from an architect of the crime (mastermind or
hintermann) as well as the foot soldiers or what the later ICTY cases often referred to as the Relevant Physical Perpetrators, or RPP.
So under the original JCE doctrine, each member of the group was prosecuted for
participating in the JCE. That was, in essence, a unitary model of perpetration. True, as a formal matter, aiding and abetting and accomplice liability survived the creation of JCE, but their relevance and practical import was greatly reduced. Most defendants at the ICTY were prosecuted under a JCE theory and it seemed to me that in most cases JCE could have replaced the other modes of liability given the collective nature of international crimes.
