Volume 2173, A-27531 Article 10 1. The present Protocol shall enter into force three months after the deposit of the tenth instrument of ratification or accession. 2. For each State ratifying the present Protocol or acceding to it after its entry into force, the present Protocol shall enter into force one month after the date of the deposit of its own instrument of ratification or accession. Article 11 1. Any State Party may denounce the present Protocol at any time by written notification to the Secretary-General of the United Nations, who shall thereafter inform the other States Parties to the Convention and all States that have signed the Convention. The denunciation shall take effect one year after the date of receipt of the notification by the SecretaryGeneral. If, however, on the expiry of that year the denouncing State Party is engaged in armed conflict, the denunciation shall not take effect before the end of the armed conflict. 2. Such a denunciation shall not have the effect of releasing the State Party from its obligations under the present Protocol in regard to any act that occurs prior to the date on which the denunciation becomes effective. Nor shall such a denunciation prejudice in any way the continued consideration of any matter that is already under consideration by the Committee prior to the date on which the denunciation becomes effective. Article 12 1. Any State Party may propose an amendment and file it with the Secretary-General of the United Nations. The Secretary-General shall thereupon communicate the proposed amendment to States Parties, with a request that they indicate whether they favour a conference of States Parties for the purpose of considering and voting upon the proposals. In the event that, within four months from the date of such communication, 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 adopted by a majority of States Parties present and voting at the conference shall be submitted to the General Assembly for approval. 2. An amendment adopted in accordance with paragraph 1 of the present article shall enter into force when it has been approved by the General Assembly of the United Nations and accepted by a two-thirds majority of States Parties. 3. When an amendment enters into force, it shall be binding on those States Parties that have accepted it, other States Parties still being bound by the provisions of the present Protocol and any earlier amendments that they have accepted. Article 13 1. The present Protocol, of which the Arabic, Chinese, English, French, Russian and Spanish texts are equally authentic, shall be deposited in the archives of the United Nations. 240
