16. A commentator has sustained a similar view: “Concerning the customary status of Article 56 (2) [of the Vienna Convention], it is possible to sustain, with relative certitude, that its fixed period of 12 months does not reflect customary law. Nevertheless, the latter seems to impose the obligation of advance notice to be given within a ‘reasonable time’; and this appears to be based on the principle of good faith...”°. 17. In the instant case, the Court ought to have pondered on what could be considered as reasonable time in this situation. And in answering this question, the Court ought to have asked itself, in line with its reasoning on the need to ensure the legal protection of the beneficiaries of the declaration made by the Respondent State under Article 34(6) of the Protocol establishing the Court, which persons or entities could be aggrieved by a sudden withdrawal of the declaration. 18. In our opinion and from a pragmatic point of view, it can be considered that those who can be aggrieved by a withdrawal without notice of the declaration are individuals and NGOs that were about to submit an application to the Court, building on the declaration to establish this Court's ratione personae jurisdiction. Along the same lines, such individuals or NGOs or had just exhausted could be those who were on the verge of exhausting local remedies, or were considering invoking the abnormal prolongation of such remedies or even their ineffectiveness. 19. If we go along with this reasoning, it becomes evident that a one-year period is excessive and therefore unreasonable. Indeed, it cannot reasonably be expected that potential Applicants in the situation described above should need one year to file their application. 20. We are of the view that a period of six months from the publication of the withdrawal should be sufficient to file an application before the Court, since any application will always be followed at a later stage by an exchange of more elaborate written 6 Theodore Christakis, “Article 56", The Vienna Conventions on the Law of Treaties, a Commentary, Olivier Corten & Pierre Klein, ed., vol Il, Oxford University Press, 2011, p.1257. 6 NG a (Z-
