The covenant-breaking State shall, after the restoration of peace, be subject to perpetual disarmament and to the regulations with regard to a peace establishment provided for new States under the terms of SUPPLEMENTARY ARTICLE IV. ARTICLE VII If any Power shall declare war or begin hostilities, or take any hostile step short of war, against another Power before submitting the dispute involved to arbitrators or consideration by the Executive Council as herein provided, or shall declare war or begin hostilities, or take any hostile step short of war, in regard to any dispute which has been decided adversely to it by arbitrators chosen and empowered as herein provided, the Contracting Powers hereby bind themselves not only to cease all commerce and intercourse with that Power but also to unite in blockading and closing the frontiers of that Power to commerce or intercourse with any part of the world and to use any force that may be necessary to accomplish that object. ARTICLE VIII Any war or threat of war, whether immediately affecting any of the Contracting Powers or not, is hereby declared a matter of concern to the League of Nations and to all the Powers signatory hereto, and those Powers hereby reserve the right to take any action that may be deemed wise and effectual to safeguard the peace of nations. It is hereby also declared and agreed to be the friendly right of each of the nations signatory or adherent to this Covenant to draw the attention of the Body of Delegates to any circumstances anywhere which threaten to disturb international peace or the good understanding between nations upon which peace depends. The Delegates shall meet in the interest of peace whenever war is rumored or threatened, and also whenever the Delegate of any Power shall inform the Delegates that a meeting and conference in the interest of peace is advisable. The Delegates may also meet at such other times and upon such other occasions as they shall from time to time deem best and determine. ARTICLE IX In the event of a dispute arising between one of the Contracting Powers and a Power not a party to this Covenant, the Contracting Power involved hereby binds itself to endeavour to obtain the submission of the dispute to judicial decision or to arbitration. If the other Power will not agree to submit the dispute to judicial decision or to arbitration, the Contracting Power shall bring the matter to the attention of the Body of Delegates. The Delegates shall in such a case, in the name of the League of Nations, invite the Power not a party to this Covenant to become _ad hoc_ a party and to submit its case to judicial decision or to arbitration, and if that Power consents it is hereby agreed that the provisions hereinbefore contained and applicable to the submission of disputes to arbitration or discussion shall be in all respects applicable to the dispute both in favour of and against such Power as if it were a party to this Covenant.
