Detention of Foreign Nationals: The Court of Cassation Reaffirms the Proportionality Assessment (Judgment No. 30357/2025)

The issue of administrative detention of foreign nationals is a matter of significant legal and social importance, intersecting with fundamental principles of our legal system and European law. In this context, the recent ruling by the First Civil Section of the Court of Cassation, with judgment No. 30357 of September 4, 2025, plays a particularly crucial role, offering essential clarifications on the application of the proportionality assessment by the validation judge. This decision not only reiterates the centrality of individual rights but also provides an interpretation geared towards the effective protection of foreign nationals.

Administrative Detention of Foreign Nationals: A Complex Framework

Administrative detention, often carried out in Centres for the Permanence of Repatriation (CPR), is a pre-expulsion measure that restricts the personal liberty of foreign citizens awaiting repatriation. While necessary in certain circumstances to ensure the execution of expulsion orders, this measure must always comply with the principles of legality, necessity, and proportionality. The relevant regulatory framework was recently updated by Decree-Law of October 11, 2024, No. 145, converted with amendments by Law of December 9, 2024, No. 187, which affected Article 14 of Legislative Decree of July 25, 1998, No. 286 (Consolidated Law on Immigration). However, the legislation cannot disregard the interpretation provided by Directive 2008/115/EC (the so-called Return Directive) and the consistent case law of the Court of Justice of the European Union, which prioritize an individualized assessment of the foreign national's situation.

Judgment No. 30357/2025: The Core of the Matter

The judgment under review, issued by the First Civil Section of the Court of Cassation, presided over by A. S. and with M. R. as rapporteur, annulled and remanded a decree by the Justice of the Peace of Caltanissetta. The reason for this annulment lies in the fact that the Justice of the Peace had denied the application of a less restrictive measure than detention in a CPR, basing his decision solely on the circumstance that the detained individual, H. P. M. L. N., was "without a passport." This reasoning, according to the Court of Cassation, is insufficient and not in compliance with current legal principles.

In matters of administrative detention of foreign nationals under the procedural regime following Decree-Law of October 11, 2024, No. 145, converted with amendments by Law of December 9, 2024, No. 187, the validation judge is required, pursuant to Article 14, paragraph 1-bis, of Legislative Decree of July 25, 1998, No. 286, as interpreted in light of Directive 2008/115/EC and the case law of the Court of Justice of the EU, to conduct a proportionality assessment of the pre-expulsion measure adopted, evaluating, in light of all the factual circumstances characterizing the foreign national's situation, whether a less burdensome measure can be applied.

This ruling by the Court of Cassation unequivocally clarifies that the validation judge has a precise obligation: to perform a "proportionality assessment" of the measure adopted. This means that it is not sufficient to merely ascertain the formal prerequisites for detention; it is essential to evaluate whether such a measure is truly necessary and proportionate to the objectives pursued, taking into account all the individual circumstances of the foreign national. The absence of a passport, while a relevant factor, cannot in itself preclude the search for alternatives that are less restrictive of personal liberty.

Beyond the Passport: The Obligation to Assess Alternative Measures

The principle of proportionality requires the judge to actively explore the possibility of applying less burdensome measures than detention in a CPR. These alternatives, provided for by the legislation, may include:

• The obligation to reside in a specific location;
• The obligation to report periodically to a police station;
• The provision of financial security (a bond);
• The availability of adequate accommodation.

Judgment No. 30357/2025 emphasizes that the judge cannot limit himself to a superficial examination but must conduct a thorough investigation, gathering all relevant information to define the foreign national's situation. Only after having ruled out the feasibility of any alternative measure can detention be considered proportionate and, therefore, validated. This approach aligns with Article 13 of the Italian Constitution, which protects personal liberty as an inviolable right, and with the orientation of the Court of Justice of the EU, which has repeatedly affirmed the residual nature of detention.

Conclusions: Towards Greater Protection of Fundamental Rights

The decision of the Court of Cassation represents a significant step towards greater protection of the fundamental rights of foreign nationals. It imposes on Justices of the Peace a more attentive and protective approach, which does not merely adhere to formal requirements but delves into the merits of the individual situation, always seeking the solution least detrimental to personal liberty. For legal professionals and citizens alike, this judgment serves as an important reminder: administrative detention is not an automatic measure but an extrema ratio, to be applied only when all other less restrictive alternatives have been concretely assessed and excluded. Case law thus continues to outline a path that, while ensuring security needs and migration flow control, never forgets the inalienable value of human dignity.
