- Third party participation — Registry
This chapter features a process called ‘intervention’, whereby a third State becomes involved in a dispute procedure between two parties, and is entitled to present its arguments and evidence to the Court. There are two possibilities for this process provided for under Article 63 of the Statute. The first is that whenever the construction (i.e., interpretation) of a convention to which States other than those concerned in the case are parties is in question, the Registrar shall notify all such States forthwith. Otherwise, every State so notified has the right to intervene in the proceedings, but if it uses this right, the construction given in the judgment will be equally binding upon it. The chapter also discusses intervention under the terms of Article 62 of the Statute, which is more general in scope.
