Data entry notes:
The Convention and the exchanges of letters constituting an amendment entered into force on 5 July 1985, the date of receipt by the Government of Switzerland of the last of the notifications in respect of the said exchanges of letters. According to article 14 of the Convention, it should have entered into force on the first day of the second month following receipt by the Government of Switzerland of the last of the notifications by which the Parties confirmed the completion of the required internal procedures. However, France did not immediately approve the Convention in its version of 3 December 1976, but proposed to the other Parties to modify the Convention. The amendment thus proposed was accepted by exchanges of letters between the Parties with the understanding that it would enter into force when all the Contracting Parties had notified the Government of Switzerland of the completion of the required internal procedures for the entry into force of the said exchanges of letters.
