Artikel 22

Should a dispute arise between two or more Contracting States as to the interpretation or application of the provisions of the present Convention, and should such dispute not be settled either directly between the parties or by the employment of any other means of reaching agreement, the parties to the dispute may, before resorting to any arbitral or judicial procedure, submit the dispute, with a view to an amicable settlement, to such technical body as the Council of the League of Nations may appoint for this purpose. This body will give an advisory opinion after hearing the parties and effecting a meeting between them if necessary.
The advisory opinion given by the said body will not be binding upon the parties to the dispute unless it is accepted by all of them, and they are free either after resort to such procedure or in lieu thereof to have recourse to any arbitral or judicial procedure which they may select, including reference to the Permanent Court of International Justice as regards any matters which are within the competence of that Court under its Statute.
If a dispute of the nature referred to in the first paragraph of this Article should arise with regard to the interpretation or application of paragraphs 2 or 3 of Article 4, or Article 7, of the present Convention, the parties shall, at the request of any of them, refer the matter to the decision of the Permanent Court of International Justice, whether or not there has previously been recourse to the procedure prescribed in the first paragraph of this Article.
The adoption of the procedure before the body referred to above or the opinion given by it will in no case involve the suspension of the measures complained of; the same will apply in the event of proceedings being taken before the Permanent Court of International Justice, unless the Court decides otherwise under Article 41 of the Statute.
