The double surname given by a person with dual citizenship to his children on the ground of one of his nationalities cannot be rectified by the civil registrar without his consent. The Supreme Court pointed out that the name attains to the right of personality guaranteed by the Constitution (Article 2). In addition, it found that the Court of merit wrongly interpreted Article 1, para. 2, of the Munich Convention on the Law applicable to Surnames and Forenames which provides that the law of the State of the new nationality shall apply just in case of change of nationality and not in case of dual nationalities.
