Part II. European Law on Nationality and Statelessness clearest attempt to contribute to progress in international law on nationality.543 Furthermore, the ECN lays down rules about the procedures relating to nationality.544 Besides the obligatory chapters on the application of the convention and final clauses, the ECN also contains an interesting chapter on cooperation between the states parties to the ECN, which relates to continuing the development of laws relating to nationality matters within Europe.545 Pursuant to these provisions, the competent authorities of the states parties shall provide the Secretary General of the CoE and, when requested, each other with information about their internal laws regarding nationality as well as developments concerning the application of the ECN.546 Also, the provisions speak more elaborately about cooperation and of exchange of information relating to voluntary acquisition of nationality.547 The results of the aforementioned obligation to provide information to the CoE should, according to the Explanatory Report, be compiled by the European Documentation Centre on Nationality in a European Bulletin on Nationality.548 The European Bulletin on Nationality used to be publicly available, but the last update is from 2004.549 It is unclear whether this information is still being collected and distributed in the context of the CDCJ, which is the CoE body which remains concerned with questions around nationality and statelessness.550 It looks like no real cooperation or exchange of information has been taking place, even though renewed efforts, like the 2021 Conference Statelessness and the Right to a Nationality in Europe: Progress, Challenges and Opportunities551, are a step in the right direction. From the ECN is, nonetheless, evident that such reporting should happen. According to the second paragraph of the same Article 23 of the ECN, the states parties are to cooperate with each other and within the framework of the CoE with the aim to deal with any problems that may arise and to promote progressive development of legal principles relating to nationality. Again, the Explanatory Report provides further explanation, and names the Committee of Experts on Nationality (CJNA) as the appropriate body for cooperation within the CoE.552 543 544 545 546 547 548 549 550 551 552 106 Gerard-René de Groot, ‘The European Convention on Nationality: A Step towards a Ius Commune in the Field of Nationality Law’ (2007) 7 Maastricht Journal of European and Comparative Law 117, 120.
