European Union – Social security. The Court of Justice of the European Union dismissed the action brought by the European Commission, seeking a declaration that, by refusing to grant the Christmas bonus provided for under Slovak law to beneficiaries residing in a member state other than Slovakia, Slovakia had failed to fulfil its obligations under, among other things, art 7 of Regulation (EC) 883/2004. The Commission had failed to establish that the constituent elements of the Christmas bonus supported its classification as an 'old-age benefit' within the meaning of art 3(1)(d) of the Regulation.
