European Union – Social security. The Court of Justice of the European Union ruled that art 46a(3)(c) of the Council Regulation (EEC) No 1408/71 had to be interpreted as encompassing the part of the benefit resulting from a period of insurance during which the person concerned had the right to obtain an exemption from affiliation to the compulsory insurance scheme, in a situation where such affiliation, during the period in question, affected the extent of the social security benefit.
