The digital revolution is creating new risks, together with multiple opportunities for communication, commerce and political participation. What Ulrich Beck described as the world risk society and what – from another perspective – Jürgen Habermas calls the “postnational constellation” is a challenge to our concepts of society and democracy. Digitisation is pushing this development towards a new dimension that allows us to speak of the “digital constellation”. Social relations are denser across borders and continents; what happens there matters here, as if it were happening on our own doorstep. New kinds of risks are arising as a side-effect of the increasing use of information technologies, while the internet also offers – for the first time – an infrastructure that makes formerly unrealistic concepts of cosmopolitan democracy (David Held) a real option. This includes the establishment of a constitutional framework for normative processes aiming at managing effectively, among other global challenges, cyber-risks at national, supra-national and global levels in a coherent way. Multilevel Constitutionalism is proposed as a means of providing a normative theory for conceptualising the constitutional structure of a layered system of governance that ensures a maximum degree of self-determination for the individual and, thus, for the democratic legitimacy of decisions made at each level, from local to global. Thus, the constitution for democratically legitimate action at the global level does not question democracy at other levels, but should be complementary, based upon functioning states, and designed to deal with issues that are beyond their reach, including cybersecurity.
