Territorial Jurisdiction in Aiding Illegal Immigration: The Crucial Clarification by the Supreme Court of Cassation with Judgment No. 21550 of 2025

The phenomenon of illegal immigration represents one of the most complex and debated challenges in the contemporary legal and social landscape. In this context, the crime of aiding illegal immigration, provided for by Article 12 of Legislative Decree No. 286 of 1998 (Consolidated Law on Immigration), plays a central role. However, its practical application often raises delicate issues, particularly regarding the determination of territorial jurisdiction, i.e., which court is called upon to judge such conduct. It is precisely on this point that the Supreme Court of Cassation has intervened with the recent judgment No. 21550, filed on June 9, 2025, offering a fundamental clarification for legal practitioners.

The Regulatory Framework and the Complex Issue of Jurisdiction

The crime of aiding illegal immigration punishes anyone who commits acts aimed at procuring the illegal entry into the territory of the Italian State, or into that of another State of which the person is not a citizen or does not have a residence permit, for non-EU citizens lacking the requirements established by law. The offense is complex and can take various forms, from transportation to the organization of actual journeys. When the conduct manifests through the transportation of individuals destined for a foreign state, and the places of entry into Italy or the commission of preliminary acts are unknown, the need arises to establish with certainty which judge has jurisdiction to proceed.

The Italian Code of Criminal Procedure establishes the general criteria for determining territorial jurisdiction: Article 8 indicates the place where the crime was consummated, while Article 9 provides for subsidiary criteria if the place of consummation is unknown. The judgment in question falls precisely within this framework, providing a specific interpretation for the most elusive scenarios, such as the one involving the defendant T. O. in the proceedings decided by the Court of Appeal of Trieste on September 24, 2024.

Analysis of Judgment No. 21550 of 2025

The ruling of the Court of Cassation No. 21550 of 2025 (President B. M., Rapporteur R. C.) addresses the case of a defendant involved in the transportation of non-EU citizens without a residence permit, with the intent of facilitating their illegal entry into a foreign state. The peculiarity of the case lies in the uncertainty regarding the exact place where the acts aimed at procuring the prior illegal entry into Italy were committed, as well as the place of actual entry of these individuals into Italian territory. In the absence of these elements, the Court of Appeal of Trieste had rejected the request, but the Supreme Court had to provide a clear legal principle to resolve the issue of jurisdiction.

The Supreme Court recalled the principles established in previous rulings (such as judgment No. 33708 of 2018 or Joint Divisions No. 40982 of 2018), but it wished to clarify a crucial point for situations where transit through Italy is merely a stopover towards a final foreign destination and the initial stages are unknown. The objective is to ensure that the crime does not go unpunished due to mere procedural difficulties related to the localization of the act.

In the context of aiding illegal immigration, when the conduct consists of transporting non-EU citizens without a residence permit to illegally procure their entry into the territory of a foreign state, and neither the place where the acts aimed at procuring the prior illegal entry of those individuals into the territory of the Italian State were committed, nor the place of their entry into the Italian State are known, territorial jurisdiction is determined, pursuant to Article 9, paragraph 1, of the Code of Criminal Procedure, in the place of passage across the Italian border towards the foreign state, as the last place where a part of the action occurred.

This maxim is of fundamental importance. It establishes that, if the place of commission of preparatory acts or the point of entry into Italy cannot be identified, jurisdiction is established in the last place where a part of the criminal action occurred. In the specific case of cross-border transportation, this means the point where individuals cross the Italian border towards the foreign state. This is an application of the "locus commissi delicti" principle in one of its broader interpretations, aiming to cover all relevant fractions of conduct for the crime.

This criterion is essential to avoid gaps in protection and to ensure the effective prosecution of criminal conduct which, by its nature, often spans multiple jurisdictions and involves elements that are difficult to ascertain. Article 9, paragraph 1, of the Code of Criminal Procedure, which governs cases of uncertainty regarding jurisdiction, finds here a practical and precise application, guiding investigators and judges.

Practical Implications and Jurisprudential Orientations

Judgment No. 21550 of 2025 provides clarity in an area where uncertainty can hinder judicial action. The practical implications are significant:

• **Legal Certainty:** It offers a uniform criterion for determining jurisdiction, reducing the scope for interpretation and procedural exceptions.
• **Effectiveness of Criminal Action:** It allows authorities to prosecute the crime even when the initial elements of the conduct are difficult to ascertain.
• **Combating Organized Crime:** It contributes to strengthening the tools for combating human trafficking, often managed by criminal organizations that exploit regulatory and procedural loopholes.
• **Jurisprudential Coherence:** It aligns with an approach that, while considering the specificities of the individual case, seeks to ensure the broadest possible extent of Italian jurisdiction for crimes that have an impact on national territory, even if the ultimate goal is another state.

This decision is in continuity with previous jurisprudence that has always sought to interpret the concept of "place of consummation" broadly for complex or protracted crimes, such as aiding and abetting. The reference to the "last place where a part of the action occurred" underscores the importance of each segment of criminal conduct.

Conclusions

The judgment of the Court of Cassation No. 21550 of 2025 represents an important piece in the mosaic of Italian jurisprudence on aiding illegal immigration. By clarifying the complex issue of territorial jurisdiction, particularly in cases of transit to foreign states, the Supreme Court has provided a valuable tool to ensure the effectiveness of justice. This orientation not only ensures the correct identification of the competent forum but also strengthens the State's ability to prosecute illicit conduct that undermines security and legality, reaffirming the fundamental principles of our legal system in the face of increasingly fluid and transnational criminal phenomena.
