The quadrangular shape of the geometry of digital power(s) and the move towards a procedural digital constitutionalism

The paper explores the evolution of private powers in the digital landscape, developing a quadrangular systematisation of such a phenomenon based on four main aspects: space, values, (private) actors, and (digital) constitutional remedies. Taking a trans‐Atlantic approach, the paper shows how these categories, typical of constitutionalism, apply to the context of the Internet and of new digital technologies both in the United States and in Europe. On the one hand, the United States has up to now maintained the supremacy of the notorious Section 230 of the Communications Decency Act. On the other hand, European legislation has undergone a significant change, moving from a phase of digital liberalism, of which the 2000 e‐Commerce Directive is the emblem, towards a new era of digital constitutionalism, passing through the age of judicial activism of European courts. In this sense, Europe has increasingly attempted to introduce limits to private (digital) powers, with a view to better protect and enforce (also horizontally) users' fundamental rights. Additionally, the evolution of digital constitutionalism, from a vertical‐sectoral approach to a horizontal and procedure‐based one, significantly showcased by the recent Digital Services Package, is underscored, signalling the recent movement of the EU into its second phase of digital constitutionalism. In this respect, the paper argues that the great benefit of stressing the procedural dimension, which may be defined as a European application of “due (data) process” to the relationship between individuals and private powers, is that it is potentially able to help consolidate a (necessary) trans‐Atlantic bridge.
