RegioPost GmbH & Co. KG v Stadt Landau in der Pfalz

European Union – Public procurement. The Court of Justice of the European Union gave a preliminary ruling, deciding, among other things, that art 26 of Directive (EC) 2004/18 had to be interpreted as not precluding legislation of a regional entity of a member state, such as that at issue in the main proceedings, which required tenderers and their sub-contractors to undertake, by means of a written declaration to be enclosed with their tender, to pay staff who were called upon to perform the services covered by the public contract in question a minimum wage laid down in that legislation.
