Administrative Detention of Foreign Nationals: The Court of Cassation (Judgment 23929/2025) and the Limits of Review

Immigration law and the procedures related to the administrative detention of foreign nationals represent a constantly evolving legal field of great social relevance. In this context, rulings by the Court of Cassation are of crucial importance, providing interpretations that guide the application of norms and the protection of fundamental rights. The recent Judgment No. 23929, filed on June 26, 2025, addresses a specific and sensitive aspect: the scope of the review of detention orders.

The Regulatory Framework for Administrative Detention

Administrative detention of foreign nationals, aimed at enforcing an expulsion order or verifying eligibility for international protection, is a measure restricting personal liberty, governed by national and European regulations. In Italy, the relevant legal framework includes Legislative Decree of October 11, 2024, No. 145, converted with amendments by Law of December 9, 2024, No. 187. At the European level, the matter is influenced by Directive 2008/115/EC (the so-called Return Directive) and Directive 2013/33/EU (the so-called Reception Conditions Directive), which provide specific procedural guarantees, including the right to review detention orders.

This oversight mechanism is essential to ensure that coercive measures are always lawful and proportionate, in compliance with Article 13 of the Italian Constitution and Article 5 of the European Convention on Human Rights (ECHR), which protect personal liberty. Review allows the detained individual to challenge the validity of the order under which they are deprived of their liberty.

Judgment 23929/2025: The Limit of Review

The Court of Cassation, with Judgment No. 23929 of June 26, 2025, has clearly defined the applicable limits of the review process. The headnote of the judgment, summarizing the legal principle enunciated, deserves careful reading:

In matters of administrative detention of foreign nationals under the procedural regime following Legislative Decree of October 11, 2024, No. 145, converted with amendments by Law of December 9, 2024, No. 187, the review of the order, permitted to individuals awaiting expulsion under Article 15, paragraph 4, of Directive 2008/115/EC, as well as to international protection applicants under Article 9, paragraph 3, of Directive 2013/33/EU, cannot be used to seek judicial ascertainment of the illegality of a justification title that is no longer effective as it has been replaced by another, not even for the purpose of pursuing compensation claims in separate proceedings. This is because it serves as a periodic review mechanism of the title under which the detention measure is currently imposed.

This ruling is of fundamental importance. The Court of Cassation establishes that review cannot be used to challenge the legality of a detention order that is no longer in force, because it has been replaced by a new title. The reason is clear: review is conceived as a control mechanism
