Artikel 26

1. The Tribunal shall make suitable provisions for the settlement of:
a) disputes arising out of contracts and other disputes of a private law character to which the Tribunal is a party;
b) disputes involving any person referred to in this Agreement who by reason of his official position enjoys immunity, if such immunity has not been waived.
2. All disputes arising out of the interpretation or application of this Agreement shall be referred to an arbitral tribunal unless the parties have agreed to another mode of settlement. If a dispute arises between the Tribunal and a State Party which is not settled by consultation, negotiation or other agreed mode of settlement within three months following a request by one of the parties to the dispute, it shall at the request of either party be referred for final decision to a panel of three arbitrators: one to be chosen by the Tribunal, one to be chosen by the State Party and the third, who shall be Chairman of the panel, to be chosen by the first two arbitrators. If either party has failed to make its appointment of an arbitrator within two months of the appointment of an arbitrator by the other party, the Secretary-General of the United Nations shall make such appointment. Should the first two arbitrators fail to agree upon the appointment of the third arbitrator within three months following the appointment of the first two arbitrators the third arbitrator shall be chosen by the Secretary-General of the United Nations upon the request of the Tribunal or the State Party.
