Judgment_paragraph 23 · Azienda Sanitaria Locale di Lecce and Università del Salento v Ordine degli Ingegneri della Provincia di Lecce and Others (C-159/11)

23As a preliminary point, it should be noted that the application of Directive 2004/18 to a public contract is subject to the condition that the estimated value thereof reaches the threshold laid down in Article 7(b) of that directive, taking into consideration the usual value on the market of the works, supplies or services to which that public contract relates. Otherwise, the fundamental rules and the general principles of the FEU Treaty, in particular the principles of equal treatment and of non-discrimination on grounds of nationality and the consequent obligation of transparency apply, provided that the contract concerned has a certain cross-border interest in the light, inter alia, of its value and the place where it is carried out (see, to that effect, inter alia, Joined Cases C-147/06 and C-148/06 SECAP and Santorso [2008] ECR I-3565, paragraphs 20, 21 and 31 and the case-law cited).
