Artikel 9

This Convention shall remain in force until terminated by one of the Contracting States. Either Contracting State may terminate the Convention, through diplomatic channels, by giving notice of termination at least six months before the end of any calendar year beginning after the expiry of five years from the date of entry into force of the Convention. In such event, the Convention shall cease to have effect from 1 January of the calendar year next following that in which the notice is given. Notice of termination shall be regarded as having been given by a Contracting State on the date of receipt of such notice by the other Contracting State.
