United Sections of the Court of Cassation: Law Firm Guarantees Apply Even to Investigated Lawyers

1. The fact

   According to reports from outlets such as NT+ Diritto de Il Sole 24 Ore and Giurisprudenza Penale, the case originates from an investigation into tax and bankruptcy crimes involving a registered professional. During preliminary investigations, the Judicial Authority ordered and executed searches at the lawyer's office and home, seizing digital media and documents without activating the special protections provided by the procedural code. The case reached the Court of Cassation after the Review Court confirmed the lawfulness of the seizure, deeming that professional guarantees did not apply to the lawyer when the investigation concerned personal matters unrelated to the defense mandate. The procedural stage saw the intervention of the United Sections of the Court of Cassation, called upon to resolve an interpretative conflict between simple sections. The central issue was whether the law firm should be considered a protected place erga omnes or if protection ceased when the lawyer acted not as a defender of third parties, but as the alleged perpetrator of an ordinary crime. The final decision established a cornerstone principle for the integrity of the procedural system and the confidentiality of third parties unrelated to the facts.

2. The rules at stake

   The regulatory core is Art. 103 c.p.p., which governs inspections, searches, and seizures in defense counsel offices. This rule provides that such acts must be performed personally by the magistrate and that notice must be given to the Bar Council so that the President can attend. The function of the rule is to prevent the indiscriminate acquisition of documents covered by secrecy. Another essential reference is Art. 200 c.p.p. on professional secrecy, which protects the confidentiality of information acquired by the lawyer. From a constitutional perspective, Art. 15, which guarantees the freedom and secrecy of correspondence, and Art. 24, which establishes the inviolability of the right of defense, are relevant. The violation of these provisions entails, pursuant to paragraph 7 of Art. 103 c.p.p., the inadmissibility of the results of the acts performed, precluding the evidentiary use of what was unlawfully seized in the law firm.

3. What the jurisprudence says

   Case law from the supreme court has clarified that the guarantees provided for law firms do not constitute a personal privilege of the professional, but are established to protect the client and the social function of the legal profession. In the past, a restrictive approach held that these protections applied only if the crime was connected to defense activity. However, the United Sections ruled that the place of professional practice deserves objective protection regardless of the nature of the alleged crime. The established principle states that if the search for evidence occurs in the firm, the procedure under Art. 103 c.p.p. must be followed even if the lawyer is investigated for personal conduct. This prevents the secrets of hundreds of clients unrelated to the investigation from being exposed to target a single suspect, thus ensuring the principle of proportionality in investigative actions. Furthermore, jurisprudence has specified that seizing entire digital archives without targeted selection conflicts with the prohibition against seizing documents related to the subject of defense.

8. What it teaches professionals

   1. Procedural vigilance: the lawyer must always demand the presence of a Bar Council delegate in case of forced entry, immediately recording any deficiency in the minutes.
   2. Data organization: clearly separating personal archives from client files facilitates defense in case of targeted seizures.
   3. Timely challenge: jurisprudence offers solid tools to appeal against generalized seizures of IT media (cloud or servers).
   4. Awareness of the role: remember that the protections of Art. 103 c.p.p. are a safeguard of freedom for the entire community.
