24 Jan Why It (Formally) Matters Whether Palestine Ratifies the Rome Statute
David Bosco has an important post at The Multilateralist today reminding people that Palestine does not have to ratify the Rome Statute for the ICC to be able to investigate the situation in the West Bank and Gaza. As David notes, because Palestine has filed a declaration under Article 12(3) accepting the Court’s jurisdiction on an ad hoc basis, the Prosecutor already has the authority to initiate an investigation, should she so choose.
That said, it still matters — at least formally — whether Palestine takes advantage of its newly-recognized statehood and ratifies the Rome Statute. The Court’s jurisdiction over a situation can be triggered in three different ways: (1) a referral by a State Party; (2) a referral by the Security Council; and (3) a decision to investigate proprio motu by the Prosecutor. Procedurally, there is a significant difference between those methods: unlike investigations triggered by a State Party or Security Council referral, the Pre-Trial Chamber has to authorize a proprio motu investigation. The relevant provision of the Rome Statute is Article 15:
1. The Prosecutor may initiate investigations proprio motu on the basis of information on crimes within the jurisdiction of the Court.
2. The Prosecutor shall analyse the seriousness of the information received. For this purpose, he or she may seek additional information from States, organs of the United Nations, intergovernmental or non-governmental organizations, or other reliable sources that he or she deems appropriate, and may receive written or oral testimony at the seat of the Court.
3. If the Prosecutor concludes that there is a reasonable basis to proceed with an investigation, he or she shall submit to the Pre-Trial Chamber a request for authorization of an investigation, together with any supporting material collected. Victims may make representations to the Pre-Trial Chamber, in accordance with the Rules of Procedure and Evidence.
4. If the Pre-Trial Chamber, upon examination of the request and the supporting material, considers that there is a reasonable basis to proceed with an investigation, and that the case appears to fall within the jurisdiction of the Court, it shall authorize the commencement of the investigation, without prejudice to subsequent determinations by the Court with regard to the jurisdiction and admissibility of a case.
The Rome Statute’s differential treatment of proprio motu investigations is not an accident. During the drafting of the Rome Statute, some states wanted the Prosecutor to have unfettered authority to initiate investigations, while others — fearing politically-motivated prosecutions — wanted to limit investigations to referrals by States Parties and the Security Council. Article 15 reflects the compromise the drafters reached: the Prosecutor would have proprio motu power, but the use of that power would always be subject to judicial review.
Why does this matter for the new state of Palestine? Because an investigation conducted pursuant to an ad hoc declaration like Palestine’s is treated as a proprio motu investigation, so the Prosecutor’s decision to investigate must be confirmed by the Pre-Trial Chamber. That was the case, for example, in Cote d’Ivoire: once the Prosecutor decided to act on Cote d’Ivoire’s ad hoc acceptance of the Court jurisdiction (retroactive, as I’ve noted before), he submitted a formal request under Article 15 to the Pre-Trial Chamber asking it to authorize the investigation — which it did.
At least procedurally, then, Palestine does indeed have a significant incentive to ratify the Rome Statute. If it ratifies, a formal referral of the situation in the West Bank and Gaza to the Court would qualify as a State Party referral under Article 14 of the Rome Statute, exempting a decision by the Prosecutor to investigate from Pre-Trial Chamber review, By contrast, if Palestine does not ratify the Rome Statute and rests on its previous ad hoc declaration, a decision by the Prosecutor to investigate would qualify as a proprio motu investigation that would require the Pre-Trial Chamber’s authorization.
As I have pointed out numerous times before, I find it inconceivable that this Prosecutor will decide to investigate the situation in the West Bank and Gaza. But if she does, it will be easier for her to open that investigation if Palestine has ratified the Rome Statute.
