Military Secrets and the Right to Defence: The Court of Cassation's Balance in Ruling No. 12096 of 2025

The delicate balance between protecting national security and the fundamental right to defence is a central theme for jurisprudence. The Court of Cassation, with Ruling No. 12096, filed on March 27, 2025, has provided a fundamental clarification regarding the disclosure of military secrets for espionage purposes. This ruling, which saw Mr. B. W. as the defendant and Dr. S. M. as the President, with Dr. R. M. as the rapporteur, rejecting the appeal against a decision of the Military Court of Appeal of Rome, establishes crucial principles for managing such sensitive proceedings.

"Discovery" and State Secrecy

The crime of disclosing military secrets is serious and requires the protection of classified information. This conflicts with the defendant's right to defence, enshrined in Articles 24 and 111 of the Constitution. The central question is whether the limitation of procedural "discovery" – the defence's access to investigation documents – can invalidate fundamental acts such as the notice of conclusion of preliminary investigations (Art. 415 bis c.p.p.) and the request for indictment (Art. 416 c.p.p.).

• "Discovery" allows the defence to access investigation documents.
• Its limitation is justified by reasons of state or military secrecy.
• The risk is the compromise of full knowledge of the charges.

The Principle Established by the Court of Cassation

The Supreme Court, with Ruling No. 12096/2025, has provided a clear answer, outlining the boundaries between military secrecy and defence guarantees. The maxim is illuminating:

In the matter of disclosing military secrets for espionage purposes, the limitation of procedural "discovery", arising from the need to preserve secrecy, does not entail the nullity of the notice of conclusion of preliminary investigations and the request for indictment, provided that the strict necessity of maintaining the restriction is adequately justified and that there are, at the same time, adequate procedural guarantees for the protection of the defendant's right to make counter-arguments.

This principle establishes that military secrecy, while limiting access, does not nullify procedural acts, provided that the "strict necessity" of secrecy is "adequately justified" and that "adequate procedural guarantees" exist for the defendant's "right to make counter-arguments." This means that, despite limitations, the defendant must be able to know the essence of the charges and defend themselves effectively. Dr. U. F., the Public Prosecutor in the proceedings, contributed to this process.

Conclusions: Defence and National Security

Ruling No. 12096 of 2025 is a landmark in Italian jurisprudence. It reiterates that, even in the presence of national security needs, the right to defence cannot be sacrificed. The key is the stringent justification of secrecy and the implementation of effective procedural guarantees. This principle ensures that the trial, even in exceptional contexts such as military secrets, remains anchored to due process, protecting individual liberty without compromising the vital interests of the State.
