Are future (lease) contracts covered by the EU public procurement directives? (C-213/13)

In his Opinion of 15 May 2014 in case C-213/13 Impresa Pizzarotti (not available in English, so the following discussion is based on my reading of the Spanish version), Advocate General Nils Wahl has addressed the tricky issue whether future lease contracts, or contracts for the lease of buildings that are yet to be constructed, are covered by the EU public procurement Directives (in particular, by Directive 2004/18, but the interpretation will remain relevant under the new Directive 2014/24, which scope has not changed as far as works contracts are concerned).
The factual background of the case is rather complicated as the Commune di Bari and the Italian Ministry of Justice kept changing the conditions of the financial arrangements concerned with the building and rental of Bari's new city of justice; but, as AG Wahl indicates in his Opinion, the legal issue to be addressed is whether transactions relating to future buildings may fall within the exception to the application of the rules on public contracts--as foreseen in Article 16(a) of Directive 2004/18 [or art 10(a) Dir 2014/24], which indicates that the Directive "shall not apply to public service contracts for: (a) the acquisition or rental, by whatever financial means, of land, existing buildings or other immovable property or concerning rights thereon".
In his view, the exception in Art 16(a) Directive 2004/18 [and now art 10(a) Dir 2014/24] can under no circumstances be interpreted in a way that covers works which execution has not yet started (para 54). On the ultimate basis of the principles of the protection of the internal market's fundamental freedoms and the promotion of effective competition (para 56), AG Wahl clearly argues that
With respect to the exclusion relating to the acquisition or lease of real estate, understood in the broad sense, I believe that it can only refer to existing assets. Indeed, a tender under the application of the rules on public procurement will have little purpose when referred to the lease or sale of an existing and well determined bulding, which is inappropriate for a confrontation with others because of its unique character. Furthermore, it appears from some preparatory works that the exclusion of contracts for lease or purchase of real estate was initially motivated by the local and non cross-border nature of these contracts. However, given that the activities in question involve the future construction of real estate and, therefore, the execution of works, the tendering process and transparency required by these rules are not inappropriate at all and therefore should be applied. Further, in my view, the reference that the provisions in question make to "other (immovable) property" should be understood in the sense that it relates to assets other than land and buildings, and not to goods whose construction has yet to be conducted. [...] In the event that a public administration chooses, within the framework of the installation of certain services, for a formula for the purchase or lease of a work to be constructed, this operation shall be subject to the procurement procedures established by the relevant regulation (Opinion in C-213/13 at paras 60 and 61, own translation from Spanish, references ommitted and emphasis added).
This reasoning must be shared, given the need to interpret the exclusions to the Directives in a restrictive manner (as the AG stresses in his Opinion, at para 58). Incidentally, it is also interesting to stress that in AG Wahl's Opinion, the fact that the aggregated consideration for the lease of the future building does not cover the costs of its construction is insufficient to alter any conclusion as to the existence of a works contracts that should have been tendered under the relevant EU rules (para 80).
In my view, this is an important case, as the adoption of the interpretation suggested by AG Wahl would come to limit the possibilities to exclude certain types of contracts that fall within the broad category of public-private cooperation from the remit of the procurement directives, and seems to put some pressure on the (increased) use of either design contests or full-fledged procurement procedures (probably, from now on, the competitive procedure with negotiation under art 29 dir 2014/24) when contracting authorities seek to have dedicated buildings constructed. Let's hope that the CJEU follows this Opinion.
