44. The Coalition is also of the view that even though the declaration of acceptance of the Court's jurisdiction is a sovereign unilateral act of a State, the said declaration creates international obligations for the accepting State. The Coalition asserts that in the event the Respondent reviews its declaration to include some reservations, pursuant to Article 19(c) of the Vienna Convention, they must not be incompatible with the object and purpose of the treaty. 45. The Coalition further notes that none of the four legal instruments establishing the judicial organs of the African Union provides for denunciation and/or withdrawal 2 , and that the same applies to the main legal instruments governing human rights in Africa. As a result, the Coalition argues that the withdrawal does not appear to be consistent with the spirit set out in the human rights legal instruments adopted by the African Union. 46. On the second issue of the legal effects of the Respondent's withdrawal, the Coalition is of the view that the Respondent would be required to serve notice of its intention to withdraw at least twelve months in advance in compliance with Article 56(2) of the Vienna Convention. 47. Finally, the Coalition takes the view that the Respondent's request to suspend pending cases before the Court breaches the provisions of international law on treaties, the Charter and Protocol. The Coalition notes that the role of the Court is to preserve, complement and reinforce progress made in the protection of human rights by the African Commission on Human and Peoples' Rights (hereinafter referred to as "the Commission") and other institutions and developments in African and international legal instruments. This specifically includes ensuring compliance with the criteria on the equality of parties to a trial, 2 These are the Protocol to the African Charter on Human and Peoples' Rights on the Establishment of the African Court on Human and Peoples' Rights, the Protocol of the Court of Justice of the African Union, the Protocol on the Statute of the African Court of Justice and Human Rights and Protocol on Amendments to the Protocol on the Statute of the African Court of Justice and Human Rights. 11
