Wiretaps and Precautionary Measures: The Court of Cassation and the Right to Defence in Ruling No. 24968 of 2025

Criminal procedural law is a constantly evolving field, where the balance between investigative needs and the guarantee of the defendant's fundamental rights is continuously redefined by jurisprudence. A significant example is offered by the recent ruling of the Court of Cassation, number 24968 of 2025, which addressed a crucial issue concerning personal precautionary measures and the role of telephone wiretaps. The decision, which involved A. G. as the defendant and Dr. F. T. as the rapporteur, clarifies fundamental aspects of the right to defence in relation to the omission of filing wiretap transcripts, rejecting an appeal against an order from the Tribunal of Liberty of Rome.

Precautionary Measures and Wiretaps: The Regulatory Framework

Personal precautionary measures are coercive instruments applied before a final judgment to ensure procedural requirements. Their application is subject to strict conditions to safeguard personal liberty. Telephone wiretaps, governed by Articles 266 et seq. of the Code of Criminal Procedure (c.p.p.), are a highly incisive means of evidence gathering. Article 268 c.p.p. regulates the documentation and filing of wiretap results. Often, the issue that arises concerns the accessibility of these materials by the defence, especially in the phase preceding the preliminary interrogation of the suspect, as provided for by Article 291, paragraph 1-quater, c.p.p., before the application of a precautionary measure.

The Legal Issue and the Position of the Court of Cassation

The focal point of Ruling No. 24968 of 2025 concerned the validity of a pre-trial detention order in the event of the failure to attach, to the Public Prosecutor's request for preliminary interrogation, the transcripts of telephone wiretapping operations. It was debated whether such an omission could lead to the nullity of the precautionary order, pursuant to Articles 292, paragraph 3-bis, and 291, paragraph 1-octies, c.p.p.

The Court of Cassation, Sixth Criminal Section, presided over by Judge P. D. S., provided a clear answer, in line with previous precedents (such as Ruling No. 26929 of 2018). Here is the summary that encapsulates the principle expressed:

In matters of personal precautionary measures, the failure to attach to the public prosecutor's request, in view of the preliminary interrogation, the transcripts of telephone wiretapping operations referred to in Article 268, paragraph 2, of the Code of Criminal Procedure does not result in the nullity of the order applying the measure, for violation of Article 292, paragraph 3-bis, of the Code of Criminal Procedure in relation to Article 291, paragraph 1-octies, of the Code of Criminal Procedure, as the right to defence is guaranteed by the direct listening to the relevant conversations and by the filing of the pertinent transcripts in the digital archive.

This principle is crucial: the Court of Cassation has established that the mere absence of transcribed records does not automatically lead to the nullity of the precautionary order. The right to defence is, in fact, ensured by the possibility of accessing direct listening to the intercepted conversations and by the filing of the relevant transcripts in the digital archive. It is not the form (the paper or attached transcript) that prevails, but the substantial accessibility to the evidentiary material.

The Role of the Digital Archive and Implications for the Defence

The ruling emphasizes the importance of the digital archive as a fundamental tool for guaranteeing the right to defence. This archive contains not only the transcripts but also the original audio recordings. Direct access to and listening of the conversations allow for a more in-depth review than merely reading the transcripts, which could contain errors or interpretations.

For criminal defence lawyers, the implications are evident:

• Timely and complete access to the digital archive of wiretaps is essential.
• The defence must actively seek to listen to the recordings directly, not limiting itself to requesting only the transcripts.
• The defence strategy must consider the availability of the audio material as a primary source of evidence.

This orientation reflects a pragmatic view of the right to defence, in line with the principles of a fair trial (Article 111 of the Constitution and Article 6 of the ECHR), which require an effective opportunity for the defendant to challenge the evidence against them.

Conclusions: Balancing Protection and Investigation

Ruling No. 24968 of 2025 by the Court of Cassation offers significant clarification on precautionary measures and wiretaps. It reiterates that the right to defence is not rigidly tied to the formality of filing transcripts, but to the substantial possibility of accessing and knowing the content of the wiretaps. If the defendant and their lawyer can listen to the relevant conversations through the digital archive, the right to defence is considered fully satisfied, and the precautionary order is not null and void.

This decision serves as a reminder for legal professionals to fully utilize available technological and procedural tools to ensure an effective defence. At the same time, it confirms the judiciary's commitment to balancing investigative needs with the protection of fundamental liberties, in an increasingly complex and digitized procedural context.
