No need to look, trust me! Mutual trust and distrust in the European arrest warrant system

Abstract

No cooperative scheme in EU law has displayed bigger tensions between mutual trust and fundamental rights protection than the EAW system. Despite the requirement developed by the CJEU for national courts to trust each other and recognise each other’s arrest warrants, the reality on the ground has shown high levels of distrust between national courts regarding Member States’ alignment with core EU values. In this contribution, we analyze how the CJEU has managed such tensions in the EAW system. To that effect, we first put the Court’s EAW case law into context by examining the broader language of mutual trust used by the Court in other fields of EU law. In doing so, we point out how the Court has espoused different levels of lawful distrust to be exercised in different circumstances under the scope of application of mutual trust. Given that broader context, it is contradictory for the Court to mainly view mutual trust as a requirement rather than a reality in need of permanent and continuing justification between national authorities. The latter conception of mutual trust is more apt to be the basis of EU horizontal cooperation, which must be value-based and sincere according to the Treaties. Therefore, we propose a bidimensional account of mutual trust as a legal principle, one that accommodates both trust and distrust as tools for managing the uncertainty and dynamic nature of trust-based cooperation. Finally, we explore how such account of mutual (dis)trust can be concretised by the Court and other political institutions.
