Artikel 21

1. If any dispute arises between the Contracting Parties relating to the interpretation or application of this Agreement, the Contracting Parties shall in the first place endeavor to settle it by bilateral negotiations.
2. If the Contracting Parties fail to reach a settlement by negotiations, they may agree to refer the dispute for decision to some person or body; if they do not so agree, the dispute shall at the request of either Contracting Party be submitted for decision to a tribunal of three arbitrators, one to be nominated by each Contracting Party and the third to be appointed by the two so nominated, provided that such third arbitrator shall not be a national of either Contracting Party. Each of the Contracting Parties shall nominate an arbitrator within a period of 60 (sixty) days from the date of receipt by either Contracting Party from the other Contracting Party of a notice through diplomatic channels requesting arbitration of the dispute by such a tribunal, and the third arbitrator shall be appointed within a further period of 60 (sixty) days. If either of the Contracting Parties fails to nominate its own arbitrator within the period specified, or if the third arbitrator is not appointed within the period specified, the President of the Council of ICAO may at the request of either Contracting Party appoint an arbitrator or arbitrators, as the case requires. In such cases, the third arbitrator shall be a national of a third State and shall act as president of the arbitral tribunal.
3. The Contracting Parties undertake to comply with any decision given under paragraph 2 of this Article. Each Contracting Party shall bear the costs of the arbitrator appointed by it. The other costs of the tribunal shall be shared equally by the Contracting Parties.
