In the system of the Protocol, the obligation to submit disputes to arbitration is sound and practical because it has always a sanction. Its application is automatically ensured, by means of the intervention of the Council; in no case can it be thrown on one side through the ill-will of one of the disputant States. The awards to which it leads are always accompanied by a sanction, adapted to the circumstances of the case and more or less severe according to the degree of resistance offered to the execution of the sentence.
The rules laid down in the Protocol do not all have the same scope or value for the future.
As soon as the Protocol comes into force, its provisions will become compulsory as between the signatory States, and in its dealings with them the Council of the League of Nations will at once be able to exercise all the rights and fulfil all the duties conferred upon it.
As between the States Members of the League of Nations, the Protocol may in the first instance create a dual régime, for, if it is not immediately accepted by them all, the relations between signatories and non-signatories will still be governed by the Covenant alone while the relations between signatories will be governed by the Protocol as well.
But this situation cannot last. Apart from the fact that it may be hoped that all Members of the League will adhere to it, the Protocol is in no sense designed to create among the States which accept it a restricted League capable of competing with or opposing in any way the existing League. On the contrary, such of its provisions as relate to articles of the Covenant will, as soon as possible, be made part of the general law by amendment of the Covenant effected in accordance with the procedure for revision laid down in Article 26 thereof. The signatory States which are Members of the League of Nations undertake to make every effort to this end.
When the Covenant has been amended in this way, some parts of the Protocol will lose their value as between the said States: some of them will have enriched the Covenant, while others, being temporary in character, will have lost their object.
The whole Protocol will remain applicable to relations between signatory States which are Members of the League of Nations and signatory States outside the League, or between States coming within the latter category.
