Artikel 14

1. Any State may, at the time of becoming a Contracting Party to this Convention, or at any time thereafter, declare by notification given to the Secretary General that the Convention shall extend to all or any of the territories for whose international relations it is responsible, named in its notification. Such notification shall take effect on the first of January which falls at least twelve months but not more than twenty-four months after the date of the receipt thereof by the Secretary General, unless an earlier date is specified in the notification. However, this Convention shall not apply to such territories before it has entered into force for the State concerned.
2. This Convention shall cease to have effect for a named territory on the date when the Contracting Party ceases to be responsible for the international relations of that territory or on such earlier date as may be notified to the Secretary General under the procedure of Article 15.
