62. In the view of the Court, the provision of a notice period is essential to ensure juridical security by preventing abrupt suspension of rights which inevitably impact on third parties, in this case, individuals and groups who are rights-holders.7 This is more so as the Protocol is an implementing instrument of the Charter that guarantees the protection and enjoyment of human and peoples' rights contained therein as well as in other relevant human rights instruments. The suddenness of a withdrawal without prior notice therefore has the potential to weaken the protection regime provided for in the Charter. 63. In a matter similar to the one at hand, the Inter-American Court of Human Rights made a determination on the basis of the principle of legal certainty by holding in the case of lvcher Bronstein v Peru that: "A unilateral action by a State cannot divest an international court of jurisdiction it has already asserted; [where] a State [is allowed to] withdraw its recognition of the Court's contentious jurisdiction, formal notification would have to be given one year before the withdrawal could take effect, for the sake of juridical security and continuity." 8 7 See Frans Viljoen International Human Rights Law in Africa (2007) Oxford at page 256 and Laurence R. Heller, Terminating Treaties in Duncan Hollis (ed.) The Oxford Guide to Treaties Oxford University Press, 2012 at pages 634-649. 8 lvcher Bronstein v Peru at paragraph 24(b). 15 64. Considering the foregoing, the Court holds that the provision of notice is compulsory in cases of withdrawal of the declaration under Article 34(6) of the Protocol. 65. Regarding the period of notice, the Court is inspired by two main practices which converge to the minimum requirement of one year. The first example is the practice of the Inter-American Court of Human Rights as provided in Article 78 of the American Convention on Human Rights and applied in the lvcher Bronstein case referred to earlier. The second illustration is the notice period provided for pursuant to Article 56(2) of the Vienna Convention. 66. In light of the foregoing and in the view of the Court, a notice period of one year shall apply to the withdrawal of the Respondent's declaration.
