The Council shall formulate and submit to the members of the League for adoption plans for the establishment of a permanent court of international justice. The court shall be competent to hear and determine any dispute of an international character which the parties thereto submit to it. The court may also give an advisory opinion upon any dispute or question referred to it by the Council or by the Assembly. Article Fifteen [Settlement of Disputes by Council or Assembly; Exclusion of Domestic Questions] If there should arise between members of the League any dispute likely to lead to a rupture, which is not submitted to arbitration as above, the members of the League agree that they will submit the matter to the Council. Any party to the dispute may effect such submission by giving notice of the existence of the dispute to the Secretary-General, who will make all necessary arrangements for a full investigation and consideration thereof. For this purpose the parties to the dispute will communicate to the Secretary-General, as promptly as possible, statements of their case, all the relevant facts and papers; the Council may forthwith direct the publication thereof. The Council shall endeavor to effect a settlement of any dispute, and if such efforts are successful, a statement shall be made public giving such facts and explanations regarding the dispute and terms of settlement thereof as the Council may deem appropriate. If the dispute is not thus settled, the Council either unanimously or by a majority vote shall make and publish a report containing a statement of the facts of the dispute and the recommendations which are deemed just and proper in regard thereto. Any member of the League represented on the Council may make public a statement of the facts of the dispute and of the conclusions regarding the same. If a report by the Council is unanimously agreed to by the members thereof other than the representatives of one or more of the parties to the dispute, the members of the League agree that they will not go to war with any party to the dispute which complies with the recommendations of the report. If the Council fails to reach a report which is unanimously agreed to by the members thereof, other than the representatives of one or more of the parties to the dispute, the members of the League reserve to themselves the right to take such action as they shall consider necessary for the maintenance of right and justice. If the dispute between the parties is claimed by one of them, and is found by the Council to arise out of a matter which by international law is solely within the domestic jurisdiction of that party, the Council shall so report, and shall make no recommendation as to its settlement.
