Supreme Court Criminal Ruling No. 12294/2025: Defendant's Opposition and Appealability of Dismissal for Particular Insignificance of the Offence

With ruling No. 12294, filed on March 28, 2025, the Fifth Criminal Section of the Supreme Court – President R. P., Rapporteur and Author I. S. – revisits the delicate balance between procedural efficiency and defence guarantees, addressing the issue of dismissal for particular insignificance of the offence (Art. 131-bis of the Criminal Code) and the appeal remedies available to the defendant. The case originated from an order by the Preliminary Investigations Judge (GIP) of S. Maria Capua Vetere, which had ordered the dismissal of the case. The defendant A. M. subsequently filed an appeal to the Supreme Court against this order.

Reference Legal Framework

The institute of particular insignificance of the offence, introduced in 2015, allows for the avoidance of trial when the concrete offensiveness appears minimal. Article 411, paragraph 1-bis, of the Code of Criminal Procedure provides that, in case of a request for dismissal on this basis, the public prosecutor must notify the victim and the defendant, who may oppose it within ten days. Only if the opposition is accepted will the GIP schedule a hearing pursuant to Art. 409 of the Code of Criminal Procedure; otherwise, they will issue an order of dismissal.

The ruling under review has considered Article 111, paragraph 7, of the Constitution, which guarantees an appeal to the Supreme Court for violation of law against decisions concerning personal liberty and, by jurisprudential extension, against orders of dismissal, as well as Articles 409-411 of the Code of Criminal Procedure and Article 127 of the Code of Criminal Procedure concerning participation in chamber hearings.

The Court's Ruling

An order of dismissal for particular insignificance of the offence is appealable by the defendant to the Supreme Court for violation of law, pursuant to Article 111, seventh paragraph, of the Constitution, only on the condition that they have previously filed an opposition pursuant to Article 411, paragraph 1-bis, of the Code of Criminal Procedure, as they cannot benefit from an opposition possibly filed by the victim.

In other words, the Supreme Court clarifies that the right to appeal to the Supreme Court arises only if the defendant has promptly activated the opposition filter. Any initiative by the victim does not compensate for the defendant's inaction: the standing to appeal remains personal and non-delegable. This prevents late appeals that would circumvent the prior adversarial principle provided by law.

Key Points of the Decision

• Centrality of the Defendant's Opposition: The Court refers to United Sections Ruling 38954/2019, reiterating that the opposition is a condition for the admissibility of the appeal.
• Autonomy of the Parties: The victim's opposition produces effects only in their favour; it does not extend its effects to the defendant.
• Balanced Constitutional Protection: The combined provisions of Art. 131-bis of the Criminal Code and Art. 111 of the Constitution require safeguarding the adversarial principle without sacrificing the reasonable duration of the proceedings.

Practical Implications for Defence

For criminal lawyers, this ruling represents a warning: neglecting the opposition leads to the preclusion of a subsequent appeal to the Supreme Court, with the definitive loss of an important guarantee of legality. It is therefore essential to:

• Promptly assess the notification of the notice pursuant to Art. 411, para. 1-bis, of the Code of Criminal Procedure.
• Formulate a reasoned opposition, indicating the elements that exclude the particular insignificance or lament procedural defects.
• Appeal to the Supreme Court only after completing this phase, focusing on violations of law.

The principle also applies to proceedings with minor charges (e.g., defamation, minor bodily harm): defence inaction cannot be remedied at the Supreme Court level. On the other hand, the victim retains their independent right to appeal, but without any impact on the defendant.

Conclusions

Ruling No. 12294/2025 enhances the case-settling function of Art. 131-bis of the Criminal Code without compromising the right to defence: the appeal to the Supreme Court remains available, but only for those who have actively participated in the adversarial process. Lawyers must therefore adopt a timely and proactive approach from the preliminary investigation phase onwards, under penalty of losing protections that cannot be subsequently recovered.
