Methods of the criminal procedural policy of the European Union

Abstract

This article provides a comprehensive analysis of the methods employed in shaping and implementing the criminal procedural policy of the European Union. Drawing on doctrinal research by J. Öberg, W. Schroeder, J. Ouwerkerk, A. Weyembergh, M. Kusak, A. Ciampi and other scholars, the study examines the content, legal foundations and interrelationships of the principal methods: mutual recognition as the cornerstone of judicial cooperation in criminal matters, characterised by W. Schroeder as a method of negative integration that removes barriers without requiring unification; harmonisation through minimum standards under Article 82(2) TFEU, with particular attention to J. Ouwerkerk’s distinction between functional approximation (serving mutual recognition) and self-standing approximation (protecting rights as an autonomous objective); the step-by-step approach exemplified by the 2009 Council Roadmap for strengthening procedural rights; enhanced cooperation as a mechanism for overcoming political deadlock in the Council; operational coordination and information exchange through specialised agencies and dedicated systems; and strategic programming through soft law instruments. The article identifies key internal tensions between methods: the contested relationship between mutual recognition and harmonisation, where J. Öberg challenges the assumption that harmonisation is a necessary precondition of mutual trust between Member States; the paradoxical role of the emergency brake mechanism; the gap between cross-border evidence gathering and admissibility highlighted by M. Kusak; and the challenges posed by digitalisation of criminal justice. The study concludes that these methods form an interconnected system of inherent compromises between cross-border cooperation effectiveness and respect for national sovereignty in criminal matters, constituting a structural feature rather than a temporary deficiency.
