The procedural system operates on a delicate balance between the need for stability in acquittal decisions and the prosecution's right to seek a new review in the appeal judgment. The recent ruling No. 15874/2025 by the Court of Cassation – Third Criminal Section – intervenes precisely on this edge, clarifying when the Public Prosecutor's appeal can be considered admissible in the absence of an indication of witnesses to be re-examined. The issue concerns the interpretation of Article 603, paragraph 3-bis of the Code of Criminal Procedure, introduced by the "Cartabia reform" to limit the overturning of acquittals on appeal based on a different assessment of testimonial evidence.
The rule requires the second-instance judge, if intending to disregard an acquittal judgment based on a different consideration of the credibility of witnesses or defendants, to proceed with the renewal of the examination. However, the provision does not expressly regulate the content of the appeal act, which continues to be governed by Article 581 of the Code of Criminal Procedure (grounds, conclusions, and, for the Public Prosecutor, indication of the contested ruling).
In matters of appeal, the omission to indicate the declarants to be examined in the second-instance judgment does not constitute grounds for inadmissibility of the Public Prosecutor's appeal against an acquittal for reasons relating to the assessment of testimonial evidence, as the provision of Article 603, paragraph 3-bis, of the Code of Criminal Procedure does not regulate the modalities of the appeal, but establishes a procedural rule that must be observed by the second-instance judge in the event of overturning an acquittal judgment based on a different appreciation of the credibility of testimonial evidence.
The Court, referring to consistent precedents (Cass. S.U. No. 14426/2019; No. 11586/2022), clarifies that Article 603, para. 3-bis does not impose an additional burden of "specifying the witnesses" within the appeal document. This requirement, in fact, pertains to the decision-making phase and rests with the judge, who is called upon to order the renewal of the investigation if they intend to overturn the acquittal for reasons related to the credibility of the statements.
The ruling under comment offers some useful indications:
In essence, the editorial practice for drafting the appeal document does not change: the specificity of the grounds and the precise reference to the evidentiary elements on which the request for reform is based remain central.
Ruling No. 15874/2025 reiterates that the admissibility filter for appeals is still based on the requirements of Article 581 of the Code of Criminal Procedure, without overlap with Article 603, para. 3-bis. This reinforces the distinction between the appeal phase and the decision-making phase: the former concerns the submission of grounds, the latter the potential "renewal" of testimonial evidence. For legal professionals, the lesson is twofold: the Public Prosecutor's appeal powers are not curtailed, while the defence can ensure that any reassessment of witness credibility occurs with respect for the adversarial principle. The principle contributes to making the appellate judgment more predictable, setting limits on purely formal challenges and focusing the Court of Cassation's review on issues of genuine guarantee.
