Tout belligérant ayant refusé l'armistice ou en ayant violé les conditions, sera réputé agresseur.
Le Conseil enjoindra aux Etats signataires d'appliquer sans retard contre l'agresseur les sanctions visées à l'article 11 du présent Protocole, et tout Etat signataire, ainsi requis, sera dès lors fondé à exercer les droits d'un belligérant.
ARTICLE 10.
Every State which resorts to war in violation of the undertakings contained in the Covenant or in the present Protocol is an aggressor. Violation of the rules laid down for a demilitarised zone shall be held equivalent to resort to war.
In the event of hostilities having broken out, any State shall be presumed to be an aggressor, unless a decision of the Council, which must be taken unanimously, shall otherwise declare:
1. If it has refused to submit the dispute to the procedure of pacific settlement provided by Articles 13 and 15 of the Covenant as amplified by the present Protocol, or to comply with a judicial sentence or arbitral award or with a unanimous recommendation of the Council, or has disregarded a unanimous report of the Council, a judicial sentence or an arbitral award recognising that the dispute between it and the other belligerent State arises out of a matter which by international law is solely within the domestic jurisdiction of the latter State; nevertheless, in the last case the State shall only be presumed to be an aggressor if it has not previously submitted the question to the Council or the Assembly, in accordance with Article 11 of the Covenant.
2. If it has violated provisional measures enjoined by the Council for the period while the proceedings are in progress as contemplated by Article 7 of the present Protocol.
Apart from the cases dealt with in paragraphs 1 and 2 of the present Article, if the Council does not at once 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 has refused to accept the armistice or has violated its terms shall be deemed an aggressor.
