The evolution of criminal procedural law has historically been characterised by a clash between two fundamental tendencies, present since the inception of the field. First, there is the pursuit of an effective criminal procedure, aimed at safeguarding society and individuals by identifying and punishing offenders. This goal is contrasted with the aim of ensuring a robust defence for every citizen subject to criminal proceedings, thereby preventing the wrongful conviction of the innocent and restricting any arbitrary or abusive exercise of state authority. Historically, the imbalance between these tendencies often stemmed from differing legal, philosophical, and political perspectives. In the 21st century, criminal procedural law faces a new challenge in balancing these traditionally conflicting aspirations due to the advent and integration of new technologies, particularly artificial intelligence (AI). This technological disruption, favouring the effectiveness of criminal prosecution, presents a dilemma for the conventionally and historically slower-evolving criminal procedural law, which struggles to respond at a pace in line with the rapid development and application of AI in criminal proceedings. The first segment of this research delves into the historical analysis of criminal procedural law, examining the interplay and shifting dominance of traditional tendencies through time. It aims to identify the challenges that influenced their interplay and, based on historical insights, presume future developments. The second part focuses on a systematic examination of individual AI systems, using specific examples of their implementation in criminal procedure. This analysis aims to determine whether these technologies genuinely represent a shift towards prioritising the efficiency of criminal proceedings over strong defence rights. Finally, the study explores current legislative responses to these emerging challenges, primarily the AI Act of the European Union and the draft AI Treaty of the Council of Europe. These legislations lay the groundwork for national responses to the utilisation of AI in criminal procedure, and their impact on the balance of traditional legal tendencies is critically assessed.
