As European Union competences gradually increase, criminal law is one of the areas of EU law on which most attention is focused. At the heart of this field, criminal procedural law is made particularly interesting by its position at the intersection of two sectors that were traditionally excluded from the European Union’s harmonisation competences: criminal law and procedural law. Harmonisation and the “cross-fertilisation” of criminal procedural law is happening first through the influence of technical and institutional adjustments necessary to improve communication and cooperation between judicial authorities or to accommodate new actors such as the European Public Prosecutor’s Office (EPPO), second through the establishment of common (or, in any case, compatible) procedural standards as a necessary complement in order to ensure the efficiency of cooperation mechanisms.

The rights of individuals in criminal procedures have been prominent on the agenda since the entry into force of the Lisbon Treaty. In this article, the authors take stock of the state of the art, evaluating the content and implementation of the 2009 “Stockholm Roadmap Directives” (ABC Directives). Furthermore, they identify the main challenges for the years ahead. The work is organised around three, closely connected issues, i.e. the need for additional minimum rules in the area of cross-border cooperation proceedings, the need for additional minimum rules on defence rights and procedural safeguards beyond the first generation of the Roadmap Directives and the need for minimum rules on remedies, in cases where rights have been violated.
