Artikel 17

1. In the event that any State submits a reservation to any of the articles of this Convention at the time of ratification or accession, the Secretary-General shall communicate the text of the reservation to all States which are Parties to this Convention, and to the other States referred to in article 13. Any Contracting Party which objects to the reservation may, within a period of ninety days from the date of the communication, notify the Secretary-General that it does not accept it, and the Convention shall not then enter into force as between the objecting State and the State making the reservation. Any State thereafter acceding may make such notification at the time of its accession.
2. A Contracting Party may at any time withdraw a reservation previously made and shall notify the Secretary-General of such withdrawal.
