41With regard to Article 6 of Directive 73/148, the Court has held that, given the lack of precision as to the means of acceptable proof by which the person concerned can establish that he or she comes within one of the classes of persons referred to in Articles 1 and 4 of that directive, it must be concluded that evidence may be adduced by any appropriate means (see, inter alia, Case C-363/89 Roux [1991] ECR I-1273, paragraph 16, and Case C-215/03 Oulane [2005] ECR I-1215, paragraph 53).
