The Impact of Intelligent Systems on the Future of Criminal Justice: Between the Right to Privacy and the Imperative of Modernization

Constitutional principles have enshrined individual rights in accordance with the guarantees imposed by the rules of a fair trial. However, modern judicial systems are increasingly incorporating technologies driven by artificial intelligence (AI), which has sparked considerable debate. Some argue that the absolute implementation of such technologies poses a serious threat to fundamental constitutional rights—particularly the right to privacy and the guarantees of due process. Others view their adoption as a transformative development in the justice sector. Among the key outcomes of AI integration into the justice system is the emergence of electronic litigation technologies, notably remote or virtual trials. While these mechanisms have significantly expedited judicial proceedings—especially by resolving disputes more quickly and reducing trial delays—they have also faced criticism. Objections have been raised at both national and international levels due to the potential challenges these mechanisms may present, especially in terms of their impact on fundamental procedural guarantees, such as the principle of adversarial proceedings and the right to a defense. Accordingly, this study aims to clarify the implications of AI systems on the right to digital privacy, particularly in the pre-trial phase, including criminal investigations. It also explores their effects on constitutional rights during electronic trial proceedings. Ultimately, the study seeks to assess the extent to which these systems succeed in upholding the principle of a fair trial.
