(c) has disregarded a unanimous report of the Council, a judicial sentence or an arbitral award recognizing that the dispute between it and the other belligerent arises out of a matter which by international law is solely within the domestic jurisdiction of the latter State, and has not previously submitted the question to the Council or the Assembly, in accordance with Article 11, or (d) has violated provisional measures enjoined by the Council {277} for the period while the proceedings are in progress as contemplated by Article 15b. Apart from the cases dealt with in sub-heads a, b, c and d of this Article, if the Council does not at once, by unanimous vote, succeed in determining the aggressor, it shall be bound to enjoin upon the belligerents an armistice, and shall fix the terms, acting if need be, by a two-thirds majority and shall supervise its execution. Any belligerent which refuses to accept the armistice or violates its terms shall be deemed an aggressor. The Council shall call upon the Members of the League to apply forthwith against the aggressor the sanctions provided by the Covenant, and any Member of the League thus called upon shall thereupon be entitled to exercise the rights of a belligerent. [Sidenote: Article 14 of the Protocol.] The Council shall alone be competent to declare that the application of sanctions shall cease and normal conditions be reestablished. Article 16. [Sidenote: This combines Article 16 of the Covenant and Article 11 of the Protocol. It omits much of the pending amendments to Article 16 of the Covenant as superfluous.] Should any Member of the League resort to war, in disregard of its covenants, it shall _ipso facto_ be deemed to have committed an act of war against all other Members of the League, which hereby undertake immediately to subject it to the severance of all trade or financial relations and to prohibit all intercourse, at least between persons resident within their territories and persons resident within the territory of the covenant-breaking State, and, if they deem it expedient, also between their nationals and the nationals of the covenant-breaking State, and to prevent all financial, commercial or personal intercourse at least between persons resident within the territory of that State and persons resident within the territory of every other State, and, if they deem it expedient, also between the nationals of that State and the nationals of every other State. It shall be the duty of the Council in such case to recommend to the several Governments concerned what effective military, naval or air force the Members of the League shall severally contribute to the armed forces to be used to protect the Covenants of the League.
