Editor’s Note: This week, in a trio of posts by Callum Musto, Marie Davoise, and Frederic Sourgens, we facilitate discussion on the nature of the International Court of Justice’s judicial function, and the occasional international arbitration appointments accepted by individual judges of the World Court. In view of H.E. President Yusuf’s October 2018 report to the U.N. General Assembly, what can be expected of the Court with respect to managing future arbitral appointments that could be issued by appointing authorities or party nominations for the Court’s individual jurists – whether in inter-State or mixed arbitral disputes?
On 25 October, in the annual address of the President of the International Court of Justice to the General Assembly, President Yusuf announced that the Court had decided to adopt new restrictions on its sitting Members acting as arbitrators in inter-State and mixed arbitration. He said:
The Court is cognizant of the fact that, while the judicial settlement of disputes offered by the Court is enshrined in the Charter, States may, for several reasons, be interested in settling their disputes by arbitration. In such instances, Members of the Court have sometimes been called upon by States to sit on the arbitral tribunals in question dealing in some cases with inter-State disputes while in others with investor-State disputes – a testament, of course, to the high esteem in which the Court’s Judges are held by the international community. Over the years, the Court has taken the view that, in certain circumstances, its Members may participate in arbitration proceedings. However, in light of its ever-increasing workload, the Court decided a few months ago to review this practice and to set out clearly defined rules regulating such activities. As a result, Members of the Court have come to the decision, last month, that they will not normally accept to participate in international arbitration. In particular, they will not participate in investor-State arbitration or in commercial arbitration. [pp. 11-12, my emphasis]
President Yusuf elaborated that while sitting judges would no longer be allowed to arbitrate in mixed proceedings, they would be permitted to do so in ‘exceptional’ circumstances in inter-State disputes, provided that their judicial activities are given ‘absolute precedence’:
… in the event that they are called upon, exceptionally, by one or more States that would prefer to resort to arbitration, instead of judicial settlement, the Court has decided that, in order to render service to those States, it will, if the circumstances so warrant, authorize its Members to participate in inter-State arbitration cases. Even in such exceptional cases, a Member of the Court will only participate, if authorized, in one arbitration procedure at a time. Prior authorization must have been granted, for that purpose, in accordance with the mechanism put in place by the Court. Members of the Court, will, however, decline to be appointed as arbitrators by a State that is a party in a case pending before the Court, even if there is no substantial interference between that case and the case submitted to arbitration. [pp. 11-12, my emphasis]
It does not appear that the Court has elected to make formal amendments to its Rules or to include a Practice Direction reflecting the new appointment policy, but rather for individual judges and the President to manage appointment requests on an individual basis. The difference in approaches taken between inter-State and mixed arbitration presumably reflects the significant jurisdictional and substantive overlaps between the Court’s activities and many inter-State arbitrations — especially under Annex VII UNCLOS — and the comparatively smaller pool of eligible arbitrators to fill these roles.
