Article 42 1. Any dispute between two or more States Parties concerning the interpretation or application of this Convention which cannot be settled through negotiation or by the procedures expressly provided for in this Convention shall, at the request of one of them, be submitted to arbitration. If within six months from the date of the request for arbitration the Parties are unable to agree on the organization of the arbitration, any one of those Parties may refer the dispute to the International Court of Justice by request in conformity with the Statute of the Court. 2. A State may, at the time of signature or ratification of this Convention or accession thereto, declare that it does not consider itself bound by paragraph 1 of this article. The other States Parties shall not be bound by paragraph 1 of this article with respect to any State Party having made such a declaration. 3. Any State Party having made a declaration in accordance with the provisions of paragraph 2 of this article may at any time withdraw this declaration by notification to the Secretary-General of the United Nations. Article 43 This Convention is without prejudice to the provisions of international humanitarian law, including the obligations of the High Contracting Parties to the four Geneva Conventions of 12 August 1949 and the two Additional Protocols thereto of 8 June 1977, or to the opportunity available to any State Party to authorize the International Committee of the Red Cross to visit places of detention in situations not covered by international humanitarian law. Article 44 1. Any State Party to this Convention 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 the States Parties to this Convention with a request that they indicate whether they favour a conference of States Parties for the purpose of considering and voting upon the proposal. 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. 2. Any amendment adopted by a majority of two thirds of the States Parties present and voting at the conference shall be submitted by the Secretary-General of the United Nations to all the States Parties for acceptance. 3. An amendment adopted in accordance with paragraph 1 of this article shall enter into force when two thirds of the States Parties to this Convention have accepted it in accordance with their respective constitutional processes. 4. When amendments enter into force, they shall be binding on those States Parties which have accepted them, other States Parties still being bound by the provisions of this Convention and any earlier amendment which they have accepted. 16
