Public interest evaluation in negotiated public-private partnership
'Public interest' has always been a necessary and unavoidable condition in Public-Private Partnership negotiated-type (PPPN), introduced in the Italian law in 1992. However, only in 2014 that the meaning of public interest has been clarified through art. 17.1 letter g) of Law no. 164/2014, by matching it with an extraordinary contribute of urbanisation. In this law the extraordinary contribution is defined by taking into account only the purely financial criteria. Instead, European Directives and case law reaffirmed the multi-dimensional connotation of public interest.
