The chapter focuses on the ‘invasion’ of technology into the functioning of public administration and how it affects the ‘political quality’ of its decision-making. The latter constitutes the main source of legitimation of administrative authorities by linking their action to an accountable representative, which is traceable, in turn, to the fundamental constitutional rule that entrusts the government to the parties with the confidence of the Parliament. By focusing on digital administration, the chapter explores new ways of functioning and accountability, and then, of legitimacy of governmental activity as opposed to political accountability. Within this scenario, it discusses how and to what extent e-government and automation are changing both the functioning of public administration and some doctrinal traditional concepts of administrative law.
