As readers no doubt know, Ukraine has accepted the ICC’s jurisdiction on an ad hoc basis for acts committed between 21 November 2013 and 22 February 2014. The self-referral has already led to a good deal of intelligent commentary — see, for example, Mark Leon Goldberg’s discussion of the politics of an ICC investigation here and Mark Kersten’s convincing argument that Russia may not be particularly opposed to an ICC investigation here. I just want to add a few additional thoughts.
Article 124 of the Ukrainian Constitution states that the administration of justice is the exclusive competence of the courts and that judicial functions cannot be delegated to other bodies or officials. The Constitutional Court noted that the jurisdiction of the ICC under the Rome Statute is complementary to national judicial systems. However, under Article 4(2) of the Rome Statute, the ICC may exercise its functions and powers on the territory of any State party, and under Article 17, the ICC may find a case to be admissible if the State is unwilling or unable genuinely to carry out the investigation or prosecution. The Court concluded that jurisdiction supplementary to the national system was not contemplated by the Ukrainian Constitution. Hence, the amendment of the Constitution is required before the Statute can be ratified.
Parliament’s acceptance of the ICC’s jurisdiction, even on an ad hoc basis, seems specifically foreclosed by the Constitutional Court’s judgment. Ukraine’s President and Parliament clearly don’t care about that inconvenient fact; will the ICC? Martin Holtermann may be right — the ICC may simply defer to Ukraine’s President and Parliament. But I can help but think it would be unseemly for an international court like the ICC to simply ignore a clear judgment issued by the highest court in a state purporting to accept its jurisdiction. At the very least, Fatou Bensouda should take the Ukraine’s internal conflict into account when she decides whether to open a formal investigation — you can bet that any suspect wanted by the ICC would challenge the legality of the self-referral in Ukraine’s domestic courts, litigation that could make it very difficult for ICC proceedings to go forward.
Relatedly, I think it’s important to remind ourselves that Ukraine’s self-referral does not mean the OTP will open a formal investigation into the situation. Diane Amann writes today that the self-referral shows “Europe is on [the] ICC docket.” That’s true — but only in the formal sense. As Mark Kersten noted in February, Europe has been on the ICC docket for a long time in terms of preliminary investigations. After all, the OTP announced the Georgia investigation in August 2008 — nearly six years ago. (Its Afghanistan investigation has been plodding along even longer, since 2007.) That hasn’t quelled the voices that have been complaining — with justification — that the ICC has been overly obsessed with Africa. So unless and until the OTP decides to open a formal investigation into the situation in Ukraine, the country’s self-referral is unlikely to have any positive effect whatsoever on the Court’s African reputation.
Finally, a brief thought on the temporal limits of the self-referral. I don’t think the ICC will reject the referral on the ground that it is too carefully tailored to ensure only one side of the conflict. (A major problem with Comoros’s Mavi Marmara state referral.) The temporal limits, however narrow, make some sense — the referral begins when Yanukovych announced Ukraine was abandoning the agreement with the European Union and ends when Yanukovych fled the country. Should Ukraine have accepted the ICC’s jurisdiction for a longer period — most notably, to include Russia’s invasion of Crimea? I had an interesting twitter debate earlier today on that issue with a bunch of smart Court-watchers, including Ryan Goodman, Eugene Kontorovich, Mark Kersten, Martin Holtermann, and David Kaye. I pointed out that it’s difficult to see what international crimes Russia committed during the invasion, other than the non-prosecutable crime of aggression. Ryan replied that a longer self-referral could give the ICC an opportunity to address important issues in the law of occupation. (See also his post here.) That’s absolutely true — but only if Russia actually violates the law of occupation, which seems unlikely given the popularity (certainly not uniform) of the invasion and annexation within Crimea itself. The wildcard is the crime that Eugene mentioned during our discussion — the transfer of civilians into occupied territory. I have no idea whether Russia intends to directly or indirectly transfer Russians into Crimea; Eugene seems to think it does, and I will defer to his greater knowledge of the situation. But my position with regard to that possibility is the same as my position on Israel’s transfer of civilians into the West Bank: whatever the merits of the allegations, the war crime is legally uncertain and factually difficult to prove, especially when the transfer is indirect instead of direct — which it is in the West Bank and would almost certainly be in Crimea. In the absence of other violations of the law of occupation, therefore, I am not sure the OTP would get involved.
I imagine we will have much more to discuss concerning the ICC and Ukraine in the weeks to come!
