Abstract
New information and communication technologies open the way to an in-depth revision of the methods of development, interpretation and execution of law in a logic of legal and state post- modernization. The digitalization of public action is part of this movement aiming at reorganizing administrative structures. Digital technological transformations do not only affect commercial sectors but are also current in public services: the e-administration is establishing everywhere at a different pace. The functioning of the State increasingly looks like that of start- ups even though the logics which guide them are a priori profoundly different. That invites us to wonder how to keep the man in control. The administration is evolving to offer a more qualitative and efficient service but at the same time asks a series of questions and contains several risks. The digital divide among citizens and the necessary training of public service agents make the digitalization of public action complex. In addition, algorithms are becoming essential tools in the administrative decision-making process. From then on, the question of personal data is at the heart of the “Platform-State” ’s strategy. When “code is law”, the colossal increase in data raises the question of their processing. Several related legal questions arise. For example, who is legally responsible for acts adopted using algorithms: the official agent? the algorithm conception? the code programmer? Thus, the digital revolution requires a legal revolution which is necessarily one step behind.
