Judgment 24362/2025: The Court of Cassation and the Right to Adversarial Proceedings in Criminal Trials

The right to adversarial proceedings is a cornerstone of our judicial system, an indispensable guarantee for every citizen. Judgment No. 24362 of June 23, 2025, by the Court of Cassation strongly reiterates this, illustrating the severe consequences of its violation, especially in criminal matters. This ruling offers crucial insights into the importance of a fair trial and the protection of individual rights. Let's explore the details and impact of this significant decision.

The Principle of Adversarial Proceedings: A Fundamental Right

Established by Article 111 of the Italian Constitution and Article 6 of the ECHR, adversarial proceedings guarantee every party to a trial the opportunity to participate, be heard, and defend themselves. It is the concrete expression of the right to defense, crucial for the legitimacy of any proceeding. Its violation is not a mere irregularity but an absolute nullity that invalidates the procedural act.

The Case: Special Detention and "De Plano" Decision

Ruling 24362/2025 analyzes an appeal against a "de plano" decree by the Surveillance Court of Catania, which had declared inadmissible a request for special detention (art. 47-quinquies of Law no. 354/1975). The Court of Cassation found that, as the exceptional cases under art. 666, paragraph 2, of the Code of Criminal Procedure (c.p.p.) for such a procedure were not met, the defendant, B. P.M. of N. M., was prevented from exercising their right to adversarial proceedings. This resulted in an absolute nullity of the measure.

In the context of cassation proceedings, where the challenged measure is affected by absolute nullity due to violation of adversarial proceedings, it must be annulled and remanded, in accordance with the general rule derivable from the combined provisions of articles 623, paragraph 1, letter b) and 604, paragraph 4, of the Code of Criminal Procedure for cases where a ground for nullity under art. 179 of the Code of Criminal Procedure is ascertained. (Case concerning a decree issued "de plano," which, despite not falling under any of the cases referred to in art. 666, paragraph 2, of the Code of Criminal Procedure, declared inadmissible the request for the application of special detention under art. 47-quinquies of Law July 26, 1975, no. 354).

This maxim from the Court of Cassation establishes that the violation of adversarial proceedings, if it constitutes an absolute nullity, requires the annulment and remand of the measure. The Court cannot decide on the merits but must refer the case back for the proceeding to be repeated correctly, in full respect of procedural guarantees. The reference to articles 623, 604, and 179 of the c.p.p. highlights how absolute nullities are such serious defects that they cannot be remedied, necessitating a new trial to restore legality and the right to defense.

Consequences and Protection of Rights

The decision has significant effects, particularly for the rights of detainees. The main implications include:

  • Strengthening the Right to Defense: The right to be heard is inalienable, even in surveillance proceedings.
  • Limits on "De Plano" Procedures: It reiterates that issuing decrees without adversarial proceedings is an exception, not the rule, especially concerning fundamental rights.
  • Guarantee of a Fair Trial: Annulment and remand ensure that justice is fair and transparent.

Conclusions: Justice in Defense of Liberties

Judgment 24362/2025 is a fundamental warning: respect for procedural guarantees, particularly the right to adversarial proceedings, is the lifeblood of a fair judicial system. Every decision affecting liberty must be preceded by a fair and transparent exchange. This ruling reaffirms a cardinal principle, strengthening confidence in the system's ability to correct errors and ensure the full protection of individual rights in criminal proceedings.
