By focusing on the encounter between justice systems and digital technology one avoids both an apocalyptic stance and an undiscerning position towards the scenarios opened by new digital tools and technological achievements in the field of legal services and justice institutions. Similarly, computational tools are applied to a massive dataset to draw information and model public services – among which legal services provided to citizens and society – with an expected higher sustainability. Still, despite the critical role played by digital infrastructures within the transformative processes undergone by the justice systems over the last decades, the “technical” dimension of these processes must not be over-estimated. In the justice system, digital devices and digital rendition of information anticipated and paved the way for the entry of digital infrastructures and digital functions, which have reshaped the behaviour, expectations, choices, and ultimately the language.
