European Union – Civil and commercial matters. Article 1 of Regulation (EU) No 1215/2012 should be interpreted as meaning that an action for payment of wage supplements in respect of annual leave pay brought by a body governed by public law against an employer, in connection with the posting of workers to a member state where they did not have their habitual place of work, or in the context of the provision of labour in that member state, or against an employer established outside of the territory of that member state in connection with the employment of workers who had their habitual place of work in that member state, fell within the scope of application of that regulation as it related to 'civil and commercial matters'. Further, such payments did not come within the concept of 'social security' and were therefore not excluded from the Regulation. The Court of Justice of the European Union so held in proceedings concerning the issue of the certificate referred to in art 53 of the Regulation for the purposes of enforcing a final judgment delivered in default in Austria against a company established in Slovenia.
