Judges ad hoc

If the Tribunal or a chamber does not include a judge of the nationality of a party to the dispute, that party may choose a person to sit as a judge. Should there be several parties in the same interest, they are considered for this purpose as one party only. Judges ad hoc need to fulfil the conditions of members, as set out in articles 2, 8 and 11 of the Statute. They participate in the case for which they are chosen on terms of complete equality with the other judges and take precedence after the members of the Tribunal and in order of seniority of age.

Since the inception of the Tribunal, judges ad hoc have been chosen in the following cases:
