Criminal Responsibility for Omissions in ICTY and ICTR Jurisprudence
The present article analyses the International Criminal Tribunals for the Former Yugoslavia (ICTY) and Rwanda (ICTR) jurisprudence on omission liability – as a perpetrator or accomplice – for crimes actively committed by others. After explaining how the Tribunals have applied the concept in relation to specific modes of liability, an in-depth assessment of the case law is undertaken with respect to relevant duties to act, the material ability to behave in accordance with such duties, the link between a failure to do so and the commission of crimes, as well as the requisite mens rea. The intellectual foundations of this form of liability remain, to a large extent, unexplored and unexplained in the jurisprudence, which sometimes even appears to treat omissions and actions as equivalent. The article addresses the potentially far-reaching implications of the Tribunals’ findings for the future and explores some of the questions yet unanswered.
