European Union – Freedom to provide services. The Court of Justice of the European Union ruled that, in a situation such as that at issue in the main proceedings, in which a tenderer intended to carry out a public contract by having recourse exclusively to workers employed by a sub-contractor established in a member state, other than that to which the contracting authority belonged, art 56 of the Treaty on the Functioning of the European Union precluded the application of legislation of the member state to which that contracting authority belonged which required that sub-contractor to pay those workers a minimum wage fixed by that legislation.
