Preventive Measures: The Court of Cassation and Limits to the Court's Powers (Judgment no. 17683/2025)

The system of preventive measures, governed by Legislative Decree 6 September 2011, no. 159 (the "Anti-Mafia Code"), represents a delicate point of balance between public safety and individual rights. The Court of Cassation, Sixth Criminal Section, with judgment no. 17683 of 4 April 2025 (filed on 9 May 2025), has provided essential clarification on the court's powers. The ruling, presided over by G. D. A. and drafted by G. A. R. P., and concerning the defendant E. C., focuses on the proceedings under art. 14, paragraph 2-ter, of Legislative Decree 159/2011. This article governs the post-detention phase, in which the court must assess the persistence of social dangerousness to decide on the execution or revocation of special surveillance.

Limits to Judicial Power: The Clarity of the Court of Cassation

The central issue concerned the possibility for the court, in this post-detention phase, to modify the category of dangerousness originally attributed to the individual, in addition to assessing its persistence. The Supreme Court responded firmly, establishing a precise limit: while the court is responsible for ascertaining the persistence of social dangerousness to decide whether to execute or revoke the measure, it is not permitted to alter the legal classification of the individual's dangerousness, placing them in a different category from that indicated in the original imposition decree.

In the matter of preventive measures, the proceedings under art. 14, paragraph 2-ter, of Legislative Decree 6 September 2011, no. 159, grant the court the power to execute the special surveillance measure or revoke it, after the cessation of detention, depending on the outcome of the due assessment of the persistence of social dangerousness, but it does not allow for the modification of the originally imposed measure by classifying the interested party in a category of dangerousness different from that indicated in the imposition decree.

This maxim is of capital importance. It reiterates that the court's judgment is strictly limited to verifying the existence of the prerequisites for the execution or revocation of special surveillance. It is not a new assessment of the "quality" of dangerousness, but rather its "persistence". This principle ensures that restrictions on personal liberty are always based on precise and non-arbitrary assessments, respecting the principles of exhaustiveness and proportionality of measures, which are fundamental in a rule of law. This orientation is in line with previous case law, such as judgments no. 20954 of 2020 and no. 34905 of 2022, which have always emphasised a rigorous and protective application of preventive measures.

Practical Implications and Guarantees for Citizens

The consequences of this ruling are significant for legal operators and for individuals subject to preventive measures. Among the key points:

• Legal Certainty: Clear boundaries are established for the court's powers, preventing arbitrary changes to legal status.
• Proportionality: The balance between security needs and rights protection is strengthened, ensuring that measures are proportionate to the dangerousness originally ascertained.
• Tool for Defence: The judgment offers a solid basis for challenging classifications in categories of dangerousness different from the initial ones.

Conclusions: A Bulwark of Legality

Judgment no. 17683 of 2025 by the Court of Cassation represents a firm point in the interpretation of preventive measures. By reiterating the limits of judicial power in assessing post-detention social dangerousness, the Supreme Court has strengthened the principles of legality and guarantee. This orientation not only contributes to greater clarity in the application of the Anti-Mafia Code but also offers more robust protection for the individuals concerned, ensuring that restrictions on their liberty are always the result of a rigorous process that respects fundamental rights. It is a call for the careful and considered application of such incisive tools, in a constant balance between security and freedom.
