European Arrest Warrant: The Court of Cassation Clarifies the Limits of the Court of Appeal (Judgment No. 23030/2025)

The European Arrest Warrant (EAW) is a cornerstone of judicial cooperation among European Union Member States, designed to simplify and expedite the surrender of wanted persons for the purpose of criminal proceedings or the enforcement of a sentence. Its effectiveness depends on the clear definition of the roles and limits of the judicial authorities involved. In this context, the recent and significant ruling by the Court of Cassation, Judgment No. 23030 of June 16, 2025, provides important clarifications on the powers of the Italian Court of Appeal in deciding on surrender.

The Context of the European Arrest Warrant and the Principle of Mutual Recognition

Introduced in Italy by Law of April 22, 2005, No. 69, the EAW is based on the principle of mutual recognition of judicial decisions, a pillar of the EU's area of freedom, security, and justice. This principle implies that decisions issued by a judicial authority of one Member State must be recognized and executed by a judicial authority of another Member State with minimal formalities. The Court of Appeal, as the judicial authority for execution, is tasked with verifying the existence of the formal requirements of the EAW and the absence of mandatory or optional grounds for refusal, as provided for in Articles 17 and 18 of Law No. 69/2005. It is crucial to understand that this mechanism was conceived to be swift and based on trust, avoiding a new assessment of the merits of the accusation by the executing State.

The Issue of Evidentiary Sufficiency: The P.G. v. L. N. Case

The case that led to the ruling by the Court of Cassation concerned a European Arrest Warrant issued against L. N. The Court of Appeal of Bari, responsible for deciding on the surrender, had requested the issuing State to transmit the precautionary measure, with the intention of assessing the so-called "evidential sufficiency," i.e., the existence of strong indications of guilt against the accused. This request, while seemingly aimed at ensuring greater protection, clashed with the nature and purpose of the EAW, generating a potential delay in the proceedings and interpretative uncertainty regarding the scope of information that could be requested under Article 16 of Law No. 69/2005. The Supreme Court, with judgment No. 23030/2025, quashed and remanded the decision of the Court of Appeal of Bari, unequivocally clarifying the limits of such investigative powers.

In matters concerning the European Arrest Warrant, the Court of Appeal cannot request the issuing State, pursuant to Article 16 of Law of April 22, 2005, No. 69, to transmit the precautionary measure in order to assess evidential sufficiency, as this is an irrelevant element for the decision on surrender. Therefore, if a request for supplementary information on this matter has nevertheless been sent, the lack of a response cannot constitute a legitimate ground for refusing the surrender itself.

This maxim crystallizes a fundamental principle: within the framework of the European Arrest Warrant, the Italian Court of Appeal cannot request the precautionary measure from the issuing State with the aim of re-examining evidential sufficiency. The reason is clear and lies in the very logic of the EAW: the assessment of evidential sufficiency is the exclusive task of the State that issued the warrant. The executing State, in this case Italy, must not and cannot delve into the merits of the accusation but must limit itself to verifying the formal conformity of the warrant and the absence of legally provided grounds for refusal. Therefore, even if such a request for supplementary information were erroneously sent, any failure to respond by the requesting State cannot in any way justify a refusal of surrender. This is because the element subject to the request is, by its nature, irrelevant for the decision on surrender.

Implications of the Judgment for European Judicial Cooperation

The ruling by the Court of Cassation, presided over by D. A. G. and with D. G. P. as rapporteur, is of crucial importance for the correct application of the European Arrest Warrant and for safeguarding the principles of trust and mutual recognition upon which it is founded. The implications are manifold and significant:

• Strengthening the Principle of Mutual Recognition: The judgment reiterates that the EAW system does not provide for a review of the merits of the accusation by the executing State, but only a verification of the formal prerequisites and grounds for refusal.
• Prevention of Unjustified Delays: Preventing requests for irrelevant information avoids procedural delays and obstacles that could compromise the effectiveness of the instrument.
• Operational Clarity for Courts of Appeal: It provides clear guidance to the Italian Courts of Appeal, limiting their scope of investigation and focusing it on aspects pertinent to the surrender decision.
• Consistency with European Jurisprudence: The decision aligns with the orientation of the Court of Justice of the European Union, which has always emphasized the trust-based and non-merits-based nature of the EAW.

This approach is fundamental to ensuring that judicial cooperation in Europe is efficient and predictable, without becoming an opportunity to re-examine decisions already made by judicial authorities of other Member States.

Conclusions

Judgment No. 23030 of 2025 by the Court of Cassation represents a firm point in Italian jurisprudence on the European Arrest Warrant. It definitively clarifies that the assessment of evidential sufficiency does not fall within the powers of the Court of Appeal when deciding on surrender, thereby strengthening the principle of mutual recognition and ensuring greater speed and effectiveness in international judicial cooperation. For legal practitioners, this ruling is an essential reminder of the peculiar nature of the EAW and the need to adhere strictly to its founding principles, avoiding expansive interpretations that could undermine its functionality. Justice, in a borderless Europe, also relies on mutual trust and respect for the decisions of others.
