Criminal Procedure Review: The Court of Cassation and Limits on Incidental Assessment (Judgment No. 24731/2025)

The Italian judicial system, while aspiring to legal certainty, provides for extraordinary mechanisms to correct judicial errors. Among these, the review of criminal proceedings represents a fundamental tool to protect citizens from unjust convictions. But what are the limits and conditions for accessing it, especially when invoking the falsity of evidence or criminal acts that formed the basis of the conviction? The Court of Cassation, with the recent Judgment No. 24731 of 2025, offers an essential clarification that deserves careful analysis.

Criminal Review: An Extraordinary Protection Mechanism

Review is an extraordinary means of appeal that allows a final criminal conviction, i.e., one that has become res judicata, to be re-examined. Its main purpose is to ensure the reopening of proceedings if new elements or circumstances emerge which, if known previously, could have led to a different outcome. The Code of Criminal Procedure, particularly Article 630, lists the exhaustive cases in which review can be requested, including precisely the discovery of false evidence or criminal acts that influenced the conviction.

Falsity of Evidence and Underlying Offenses: The Principle of Legal Certainty

The core of the issue addressed by Judgment No. 24731/2025, issued by the Fifth Criminal Section of the Court of Cassation, presided over by P. R. and with F. C. as rapporteur, concerns the necessity of an irrevocable assessment of the falsity of evidence or the existence of criminal acts that would have led to the conviction of the defendant, in this case C. S. The Court reiterated a consolidated principle, but one often subject to different interpretations, regarding the admissibility conditions for a review request. The focal point is that it is not sufficient to "allege" falsity; it is necessary for such falsity to have been definitively ascertained. This ensures the stability of judicial decisions and prevents frivolous or dilatory requests.

In matters of review, a request alleging the falsity of evidence or that the conviction was rendered as a result of false documents or false testimony, or another offense, is not admissible in the absence of an irrevocable assessment of the alleged falsity or the existence of the criminal acts forming the basis of the conviction. The review judge may proceed to an incidental assessment only if, for the criminal acts that constitute the premise of the review request, a cause of extinction has occurred that prevents a principal assessment on the merits.

This maxim crystallizes a fundamental principle: review cannot be transformed into a new level of judgment where the assessment of falsity or the underlying offense is reopened. For its admissibility, a final judgment on the offenses that determined the falsity or the commission of the criminal act is required. In other words, before a review of the main conviction based on false evidence can be sought, the falsity itself must have been ascertained by a final judgment in separate proceedings. This avoids a "trial within a trial" and protects legal certainty.

The Crucial Exception: Incidental Assessment by the Review Judge

The Court of Cassation's judgment, however, does not merely reiterate the general rule but also highlights an important exception, already outlined in previous case law (such as Judgments No. 40169 of 2009 and No. 5026 of 2010). The review judge may proceed to an incidental assessment of the falsity or the existence of the underlying criminal acts only in a specific case: when a cause of extinction of the offense has occurred for such acts. This means that if the offense that generated the falsity or the criminal act (e.g., perjury or corruption) has been extinguished (due to statute of limitations, amnesty, death of the offender, etc.), thus preventing a "principal" assessment on the merits, the review judge has the discretion to evaluate it independently. This derogation is crucial because it would prevent the convicted person from obtaining justice for a mere procedural reason, should the underlying offense no longer be subject to independent judgment. This possibility represents a balance between the stability of the judgment and the right to a fair trial, invoking principles of substantive justice.

Conclusions and Practical Implications

Judgment No. 24731/2025 of the Court of Cassation, by confirming a consolidated jurisprudential trend, reiterates the seriousness and extraordinary nature of the criminal review mechanism. For those intending to avail themselves of this remedy, it is essential to understand that the mere allegation of falsity is not sufficient. An irrevocable assessment of the underlying offense or the falsity of the evidence is required. The only exception to this strict rule occurs when a cause of extinction prevents such principal assessment, allowing the review judge to evaluate the matter incidentally. This orientation is rooted in important provisions of the Code of Criminal Procedure, including:

• Article 630, paragraph 1, letter d), which defines the cases for review;
• Article 633, paragraph 3, which governs the procedures for submitting the request;
• Article 634, concerning the inadmissibility of a review request.

For legal professionals and citizens, understanding these distinctions is essential for navigating the complex landscape of criminal law with awareness and for best protecting their rights.
