The proposal for Regulation 2017/1939 establishing the European Public Prosecutor’s Office (The EPPO Regulation) was criticized for completely excluding the Court of Justice of the European Union (CJEU) from judicial review of decisions on forum of prosecution by the EPPO, an EU body. The system of judicial review under the EPPO Regulation has improved significantly relative to its initial proposal, by enabling national courts to refer preliminary questions to the CJEU. Despite this, several issues remain. This article examines whether the limitations imposed by the EPPO Regulation on the use of the action for annulment procedure laid down in Article 263 TFEU comply with EU primary law. More specifically, whether it complies with effective judicial protection as protected under Article 47 CFR, and the legal basis for the EPPO’s system of judicial review, Article 86(3) TFEU. We argue that the preliminary reference procedure is not effective enough in remedying the limited access to the action for annulment procedure to reliably safeguard the defendants’ right to effective judicial protection. To the extent that the current system for judicial review under the EPPO Regulation is at odds with the Article 47 CFR, the EU legislator did not have the competence to enact it under Article 86(3) TFEU. This article proposes that in order to circumvent the unlawful restrictions imposed by the EPPO Regulation, defendants could and should make use of the action for annulment procedure to contest the EPPO’s choice of forum.

The choice in the EPPO Regulation to establish the material scope of the EPPO by referring to the provisions in the PIF Directive “as implemented by national law” implies that the exact scope of competence of this first European investigating and prosecuting authority finally arises out of national legislations. As a result, the latter becomes decisive in setting the boundaries of individual responsibility in the concrete case. As it was in the past under the force of the third pillar instruments, the level and quality of implementation at national level remain crucial. The first report of the Commission on the implementation of the PIF Directive did raise several critiques in this respect. As a matter of fact, a significant number of infringement proceedings have been launched by the Commission following the worrying findings of the Implementation Report on the PIF Directive.

The legal framework under which the European Public Prosecutor’s Office (EPPO) is called to operate is particularly complex, given the need for this body to exercise its functions in the legal systems of the Member States, applying both Union and national law. While this may justify the many references to national law contained in the EPPO’s founding Regulation (2017/1939), several among these references present relevant interpretative issues, and may in some cases even have a misleading effect. The article aims at showing examples of these different scenarios. It also touches briefly on the relevance of soft law in the legal framework of the EPPO.

The first of June 2021 marked the start of the operational activities of the European Public Prosecutor’s Office (EPPO). Established by Regulation (EU) 2017/1939 (‘EPPO Regulation’), the EPPO is the European Union body competent to investigate, prosecute and bring to judgment the perpetrators of criminal offences affecting the Union’s financial interests. The EPPO was established by means of enhanced cooperation. At the time of writing, five Member States do not participate in the EPPO: Denmark, Ireland, Poland, Hungary and Sweden. The effective action against crimes affecting the Union budget requires however smooth cooperation between the EPPO and its counterparts not only in the Member States that participate in the enhanced cooperation, but also in the non-participating Member States. This contribution delves into such cooperation and the several issues it raises, first providing for some introductory remarks on the choice of some Member States not to join the enhanced cooperation on the EPPO. It then analyses the two main provisions of the EPPO Regulation concerning the EPPO’s relations with non-participating Member States, Article 99 and, most importantly, Article 105. Finally, this contribution shortly addresses the relevant role played by Eurojust in this context.

The issue of cross-border admissibility of evidence is a recurring theme of European Criminal Justice, and continues to be perceived as a decisive obstacle hindering the effective prosecution and adjudication of crime. In spite of this, the EPPO Regulation does not include an extensive framework guaranteeing the cross-border admissibility of evidence. In this article, it is argued that this lacuna is far less worrisome than it seems: the boundaries set out by EU primary law, in particular Article 325(4) TFEU and the Charter of Fundamental Rights (CFR), as well as the opportunity of the ECJ to judge on these boundaries, allow for a sufficient convergence of national laws and practices on the (in-)admissibility of evidence.

The article analyses the first question referred to the Court of Justice of the European Union for a preliminary ruling in a case concerning the European Public Prosecutor’s Office (EPPO). It involves the interpretation of a key provision regarding the investigations of this new office, i.e. Art. 31 of Council Regulation EU 2017/1939. This provision governs investigative measures that need to be undertaken in a Member State other than the Member State of the handling European Delegated Prosecutor. In the case at issue, the Oberlandesgericht Wien, Austria is seeking clarification as to the extent of judicial review if it comes to cross-border investigations within this regime. The author argues that the case raises a number of key issues for the functioning of the EPPO regarding its structure and operation, not to mention the EPPO’s relevance in the creation of a common area of justice in the European Union.
