MH17 Should Be Framed as Murder, Not as a War Crime
It has become quite common to describe the downing of MH17 as a war crime. In late July, for example, Navi Pillay, the UN High Commissioner for Human Rights, said that “[t]his violation of international law, given the prevailing circumstances, may amount to a war crime,” More recently, William Burke-White has said that, for framing purposes, “[t]he time has come for governments and international organizations to call the attack on MH17 a probable war crime.”
[I]f whoever launched the missile did so with the intent of killing the civilian passengers aboard MH17, the act was unmistakably a war crime.
Even if the objective was to strike a Ukrainian transport aircraft, the act likely constitutes a war crime. Fundamental to the law of war, including the law applicable in non-international armed conflicts, is the principle of distinction – the requirement that fighting parties distinguish between civilian and military targets. In the words of the International Committee of the Red Cross, that duty of care includes doing “everything feasible to verify that targets are military objectives.”
In this case, many steps could easily have been taken to differentiate MH17 from a military-transport plane, including visual identification (perhaps with binoculars), radar-signature analysis, and a check of the civilian aircraft transponder-code broadcast. If, as seems likely, these basic steps were not taken, even an accidental strike on MH17 would constitute a war crime.
If the Ukrainian separatists did indeed intend to kill civilians, Bill and Navi Pillay are absolutely right to describe the attack as a war crime — in this case, murder and/or intentionally directing attacks at civilians or civilian objects (to use the Rome Statute’s terminology). But everything we know to date about the attack indicates that the separatists honestly believed MH17 was a Ukrainian military transport, not a civilian airplane. If so, that changes the legal assessment of the attack considerably. The attack would still qualify as murder under domestic law — but it would not qualify as a war crime, under either the Rome Statute or the jurisprudence of the ICTY. (The latter likely representing the customary definition of the war crimes of murder and attacking civilians or civilian objects, which most states would apply in a prosecution based on universal jurisdiction.)
Let’s go in order. The problem with describing the attack on MH17 as a war crime under the Rome Statute is Article 32(1), which provides that “[a] mistake of fact shall be a ground for excluding criminal responsibility only if it negates the mental element required by the crime.” The actus rei of the war crime of murder and the war crime of intentionally directing attacks at civilians or civilian objects each include a circumstance element: the individuals attacked must qualify as civilians (or as otherwise protected persons). The relevant mens rea for circumstance elements is knowledge, pursuant to Art. 30(3) of the Rome Statute: “For the purposes of this article, ‘knowledge’ means awareness that a circumstance exists.” Black-letter criminal law provides that an honest mistake of fact negatives any mens rea that requires subjective awareness. So if the separatists honestly believed they were attacking a Ukrainian military transport, they were not aware that they were attacking civilians. In which case they could not be convicted of either the war crime of murder or the war crime of intentionally directing attacks at civilians or civilian objects.
The result is no different under the ICTY’s jurisprudence, even though the ICTY applies a lower mens rea to the war crimes of murder and attacking civilians. A complete discussion of the issue is beyond the scope of this post; suffice it to say here that an accused will be responsible for either war crime only if he was reckless toward the possibility that the objects of his attack qualified as civilian. (Dolus eventualis in civil-law terminology.) Recklessness is a subjective mental state in the ICTY’s jurisprudence; as the Trial Chamber noted in Brdjanin, specifically in the context of murder, “the threshold of dolus eventualis… entails the concept of recklessness, but not that of negligence or gross negligence.” Like the ICC, the ICTY recognizes mistakes of fact. As a result, the separatists could not be convicted of either the war crime or murder or the war crime of attacking civilians under ICTY jurisprudence if they honestly believed they were attacking a Ukrainian military transport: although that belief might have been negligent, even grossly negligent, its honesty meant that they were not subjectively aware they were attacking civilians.
The bottom line is that the accidental downing of civilian airplane based on an honest belief that the airplane was a military objective is not a war crime. Failing to take adequate precautions may violate IHL, but it is not criminal. The downing of MH17, therefore, should be framed not as a war crime but as murder.
