At any time thereafter, such extensions shall be notified to the Ministry of Foreign Affairs of the Netherlands.
The extension shall have effect as regards the relations between the Contracting States which have not raised an objection to the extension in the twelve months after the receipt of the notification referred to in sub-paragraph 4 of Article 37 and the territory or territories for the international relations of which the State in question is responsible and in respect of which the notification was made.
Such an objection may also be raised by Member States when they ratify, accept or approve the Convention after an extension.
Any such objection shall be notified to the Ministry of Foreign Affairs of the Netherlands.
