Sometimes, it seems that it is the reality of international law that provides one with questions of treaty law that probably even a sophisticated international law professor would have had problems inventing.
On November 19, 2014, San Marino became the 19th State to have ratified the amendments to the Rome Statute on the crime of aggression. At the same time, Art. 15bis, para 2 and Art. 15ter, para. 2 of the Rome Statute in identical terms provide that “[t]he Court may exercise jurisdiction only with respect to crimes of aggression committed one year after the ratification or acceptance of the amendments by thirty States Parties” and further provided that under Art. 15bis, para. 3 and Art. 15ter, para. 3 respectively, a decision has been adopted by the Assembly of States Parties to activate the Court’s jurisdiction concerning the crime of aggression, such decision to be taken at the earliest in 2017.
What is worth noting, however, is that by now there are also eleven States, namely Cabo Verde, Côte d’Ivoire, Grenada, Guatemala, the Maldives, the Phillipines, St. Lucia, Tunisia, Vanuatu, Moldova and the Seychelles that have ratified the Rome Statute after the Kampala amendment on the crime of aggression was adopted. All of those States, when ratifying the post-Kampala Rome Statute, did so without expressing an intention not to be bound by the treaty as amended. This raises the intriguing question whether 19 + 11 equal 30, i.e. whether these new contracting parties ought to be counted towards the quorum required, as mentioned, by Art. 15bis, para 2 and Art. 15ter, para. 2 of the Rome Statute in order for the Court to exercise its jurisdiction.
