1. Any State Party may propose an amendment or revision to the present Convention and file it with the depositary. The Secretary-General of the United Nations shall thereupon communicate the proposed amendment or revision to the States Parties with a request that they notify him whether they favour a conference of States Parties for the purpose of considering and voting upon the proposal. In the event that at least one third of the States Parties favour such a conference, the Secretary-General shall convene the conference under the auspices of the United Nations. Any amendment or revision adopted by the majority of the States Parties present and voting at the conference shall be submitted to the General Assembly of the United Nations for approval.

2. Amendments or revisions shall come into force when they have been approved by the General Assembly and accepted by a two-thirds majority of the States Parties, in accordance with their respective constitutional processes.

3. When amendments or revisions come into force, they shall be binding on those States Parties which have accepted them, other States Parties still being bound by the provisions of the present Convention and any earlier amendment or revision which they have accepted.
