Artikel 27

The Convention shall apply to all non-metropolitan territories for the international relations of which any Party is responsible except where the previous consent of such a territory is required by the Constitution of the Party or of the territory concerned, or required by custom. In such a case the Party shall endeavour to secure the needed consent of the territory within the shortest period possible, and when the consent is obtained the Party shall notify the Secretary-General. The Convention shall apply to the territory or territories named in such a notification from the date of its receipt by the Secretary-General. In those cases where the previous consent of the non-metropolitan territory is not required, the Party concerned shall, at the time of signature, ratification or accession, declare the non-metropolitan territory or territories to which this Convention applies.
