Constitutional Court: Partial Unconstitutionality of Prevention Seizure Regulations

7 min read · Updated October 2026 · Editorial oversight: Avv. Federico Papa

With a recent decision regarding appeals, the Constitutional Court has enhanced protections within the system of asset prevention measures. As reported in the legal press over the past month, the decision addresses the asymmetry in the Antimafia Code that prevented private individuals from effectively challenging the rejection of a seizure revocation request, unlike the rights granted to the prosecution. While other aspects of the penal system and offenses against public administration have been examined in dedicated analyses of related cases, this ruling specifically addresses asset protection. This intervention by the Court restores a fundamental balance between the imperative to combat organized crime and the rights of property and defense. Through the analysis of the actual case and the educational reconstruction of our twin case, we explore how this turning point affects the management of seized assets and the procedural strategies of interested third parties.

Constitutional Court: Partial Unconstitutionality of Prevention Seizure Regulations

In brief

This article examines the Constitutional Court ruling that declared Article 27 of the Antimafia Code unconstitutional insofar as it denies private parties the right to appeal the rejection of a revocation request for a prevention seizure. It analyzes the principle of equality of arms and the departure from previous jurisprudence that restricted the defense of third-party owners. Through the case of Gaio Sventura, it illustrates the newly available procedural protections.

  1. The fact

    The case originates from asset prevention proceedings initiated against an individual suspected of belonging to criminal organizations. According to NT+ Diritto and QuotidianoPiù, an entrepreneur saw his assets, including real estate and business units, subject to a prevention seizure ordered by the Rome Court of Appeal. The entrepreneur claimed to be the legitimate owner or lessee of these assets and completely unrelated to the criminal conduct alleged against the primary subject. The entrepreneur had therefore filed a request for revocation of the measure, arguing the lack of legal grounds for the seizure. However, the Court of Appeal declared the application inadmissible, applying the strict literal wording of the provision, which did not provide for an independent appeal by a private party against the rejection of revocation. Upon appeal to the Court of Cassation, the United Sections raised a question of constitutional legitimacy, recognizing a violation of the right of defense. The case was thus caught in a procedural deadlock, leaving the owner effectively unable to challenge the court's error prior to final confiscation.

  2. The rules at play

    The core of the issue is Art. 27 of Legislative Decree 159/2011 (Antimafia Code), which governs the appeal of seizure orders. Prior to the ruling, the provision explicitly allowed the Public Prosecutor to appeal the revocation of a seizure, but failed to recognize a corresponding right for private parties in the opposite scenario where revocation was denied. Secondly, Art. 111 of the Constitution comes into play, enshrining the principle of a fair trial and equality of arms between prosecution and defense. The Court also invoked Art. 24 of the Constitution, protecting the right of defense at every stage and degree of proceedings, and Art. 1 of the First Additional Protocol to the ECHR, for the protection of property, ensuring it cannot be restricted indefinitely without an immediate and effective mechanism of judicial review against potential errors.

  3. What the jurisprudence says

    Prior to the Constitutional Court's intervention, jurisprudence adhered strictly to a formalistic interpretation of the prevention system. It was held that a seizure was merely provisional and that full defense rights could only be exercised against the final confiscation order. Case law from the Court of Cassation had repeatedly emphasized that the system of procedural remedies is exhaustive, prohibiting analogy to create new rights of appeal. However, growing awareness of the excessive duration of prevention proceedings prompted judges to reconsider the damage caused by an erroneous seizure maintained over many years. The turning point occurred when the United Sections observed that the procedural disparity between the prosecutor and private parties was not justified by any legitimate efficiency needs, resulting in an unacceptable vulnus to the balance of constitutional values.

  5. What it teaches professionals

    1. Timely appeals: with the availability of this new remedy, appeals against decisions denying revocation must be filed promptly to prevent irreversible financial prejudice.
    2. Representation of third parties: counsel must attentively protect clients who qualify as interested third parties in prevention proceedings directed against others, acting proactively to safeguard their property rights.
    3. Importance of documentary proof: defense in asset prevention litigation relies heavily on granular financial reconstruction, which should be comprehensively documented upon initial application for revocation.
    4. Constitutional challenges: the decision illustrates that when procedural imbalances occur, raising constitutional objections remains a critical strategy to uphold fair trial standards.

Frequently asked questions

Can I appeal the seizure of my assets if I am not under investigation?

Yes, if your assets are subjected to a prevention seizure in proceedings against another party, as an uninvolved owner you may petition for revocation and, if rejected, independently appeal the decision pursuant to the Constitutional Court's ruling.

What are the practical consequences of the Court's decision?

The ruling eliminates the disparity between prosecution and defense: whereas previously only the Prosecutor could appeal a revocation order, private parties may now also appeal decisions denying revocation, securing prompt judicial review.

Within what time limit can I request the revocation of a prevention seizure?

A revocation petition may be submitted at any time if new evidence emerges or if the grounds for the measure no longer exist; however, prompt action is recommended to mitigate financial injury.
