It can be observed that joint procurement and the new European procurement directives conceptually converge. The new rules do not only support aggressive centralization, but are likewise supportive of voluntary common purchasing of contracting authorities. In the following I put forth some excerpts of Directive 24/2014/EU, formulating the view that a fundamental misunderstanding regarding joint public procurement stems from the public procurement directive, which leads to the opposite of its original purpose, as described in the Preamble of the Directive. I also assume that by joint procurement we mean the one of contracting authorities, entities that work together, thus I do not deal with in-house collaborations of public procurements (Art. 12(4)).
