Judgment_paragraph 19 · Bestuur van de Sociale Verzekeringsbank v M. G. J. Kits van Heijningen (C-2/89)

19The sole purpose of Article 13(2)(a) of Regulation No 1408/71 is to determine the national legislation applicable to persons employed in the territory of a Member State. As such, it is not intended to lay down the conditions creating the right or the obligation to become affiliated to a social security scheme or to a particular branch under such a scheme. As the Court has pointed out several times, it is for the legislature of each Member State to lay down those conditions (see, in particular, the judgment of 23 September 1982 in Case 275/81 Koks v Raad van Arbeid [1982] ECR 3013).
