Disputes to be submitted to arbitration.
Art. XII.—The high contracting parties agree that should disputes arise between them which cannot be adjusted by the ordinary processes of diplomacy they will in no case resort to war without previously submitting the questions and matters involved either to arbitration or to inquiry by the Executive Council, and until three months after the award by the arbitrators or a recommendation by the Executive Council, and that they will not even then resort to war as against a member of the League which complies with the award of the arbitrators or the recommendation of the Executive Council.
In any case under this article the award of the arbitrators shall be made within a reasonable time, and the recommendation of the Executive Council shall be made within six months after the submission of the dispute.
The Executive Council to act if arbitration fails.
