The present study aims to retrace the digitalization process of the public procurement starting from the previsions of the legislative decree n. 50/2016 to Public Procurement digitalization decree n. 148/2021, embraced with over four years delay compared with the previsions. For this purpose, we face the extremely wide jurisprudential production in matter of telematic tendering procedures. Namely, the decree is inserted in a context in which the jurisprudence has extensively addressed the issues related to the digitalization of the tendering procedures, attempting to make this heavy jurisprudential stratification, not devoid of inconsistencies and relevant developments.
