Article 15

This Convention shall apply to all non-self-governing, trust, colonial and other non-metropolitan territories for the international relations of which any Contracting State is responsible; the Contracting State concerned shall, subject to the provisions of paragraph 2 of this Article, at the time of signature, ratification or accession, declare the non-metropolitan territory or territories to which the Convention shall apply ipso facto as a result of such signature, ratification or accession.

In any case in which, for the purpose of nationality, a non-metropolitan territory is not treated as one with the metropolitan territory, or in any case in which the previous consent of a non-metropolitan territory is required by the constitutional laws or practices of the Contracting State or of the non-metropolitan territory for the application of the Convention to that territory, that Contracting State shall endeavour to secure the needed consent of the non-metropolitan territory within the period of twelve months from the date of signature of the Convention by that Contracting State, and when such consent has been obtained the Contracting State shall notify the Secretary-General of the United Nations. This Convention shall apply to the territory or territories named in such notification from the date of its receipt by the Secretary-General.

After the expiry of the twelve-month period mentioned in paragraph 2 of this Article, the Contracting States concerned shall inform the Secretary-General of the results of the consultations with those non-metropolitan territories for whose international relations they are responsible and whose consent to the application of this Convention may have been withheld.
