Article 40 Territorial Application Clause

Any State may, at the time of signature, ratification or accession, declare that this Convention shall extend to all or any of the territories for the international relations of which it is responsible. Such a declaration shall take effect when the Convention enters into force for the State concerned.

At any time thereafter any such extension shall be made by notification addressed to the Secretary-General of the United Nations and shall take effect as from the ninetieth day after the day of receipt by the Secretary-General of the United Nations of this notification, or as from the date of entry into force of the Convention for the State concerned, whichever is the later.

With respect to those territories to which this Convention is not extended at the time of signature, ratification or accession, each State concerned shall consider the possibility of taking the necessary steps in order to extend the application of this Convention to such territories, subject, where necessary for constitutional reasons, to the consent of the Governments of such territories.
