This issue of the Revue Internationale de Droit Pénal presents a first selection of contributions from the XIII AIDP Young Penalists Symposium, entitled “Responses to Organised Crime: Between Tradition and Innovation”, held at the University of Rome Unitelma Sapienza on 10-11 October 2025 and jointly organised by Unitelma Sapienza, the AIDP Young Penalists Committee, and the Italian National Group of the AIDP.Bringing together young scholars from a wide range of jurisdictions, the volume explores the evolving landscape of legal responses to organised crime along three main axes: the expansion of non-criminal and hybrid enforcement tools, the growing centrality of economic and transnational criminal activities, and the challenges faced by criminal procedure and international cooperation.The contributions highlight the progressive hybridisation of enforcement strategies and reveal the persistent tension between effectiveness and fundamental guarantees. In doing so, the volume offers a critical and comparative perspective on the shifting boundaries of contemporary criminal law.Emanuele Birritteri is Tenure-Track Assistant Professor of Criminal Law at the University of Rome Unitelma Sapienza.
