ECJ 13 September 2017, case C-570/15 (X), Free movement, Social insurance
A Dutch employee who resides in Belgium and performs only 6.5% of his hours worked in Belgium (and the rest in the Netherlands), cannot be regarded as ‘normally’ pursuing an activity in two or more Member States. The special rule in Article 14(2)(b)(i) of Regulation No 1408/71, stating that a person normally employed in the territory of two or more Member States shall be subject to the legislation of the Member State in whose territory he resides, does not apply in this case.
