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 on the Rights of the Child 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 of the United Nations 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 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 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. 2. The Secretary-General of the United Nations shall transmit certified copies of the present Protocol to all States Parties to the Convention and all States that have signed the Convention. 4
