International drug trafficking: the Court of Cassation annuls pre-trial detention due to lack of serious evidence

The Court of Cassation, Third Criminal Section, with sentence no. 8657 of 2026, annulled the order with which the Milan Court of Review had ordered pre-trial detention in prison against an entrepreneur operating in the international transport and logistics sector, investigated as part of proceedings relating to alleged international drug trafficking.

Accepting the appeal filed by the defense, the Supreme Court found significant deficiencies in the reasoning of the precautionary measure, deeming that the existence of the serious evidence of guilt required by art. 273 c.p.p. for the application of a custodial measure had not been adequately demonstrated.

The Court of Cassation therefore ordered the annulment of the order of the Milan Court of Review, with remand to the same judge so that he may proceed with a new and more in-depth evaluation of the evidentiary framework, in light of the principles of law set out in the decision.

The case: investigations into an alleged international drug importation

The proceedings originated from an investigation by the Public Prosecutor's Office relating to an alleged operation to import approximately 200 kilograms of cocaine into Italy, which, according to the prosecution's hypothesis, would have been organized through a network of international contacts.

Among the subjects involved in the investigations was also an entrepreneur operating in the international transport and logistics sector, a business area which, by its nature, involves the management of commercial relations with foreign operators and the transnational movement of goods.

In the precautionary phase, the Judge for Preliminary Investigations had initially excluded the existence of the prerequisites for the application of a custodial measure.

Subsequently, however, the Milan Court of Review, accepting the appeal filed by the public prosecutor, reformed this decision, deeming that serious evidence of guilt existed based on a series of investigative elements, including:

• some telephone interceptions between the subjects involved in the investigations;
• alleged contacts with South American operators;
• the trip to Colombia of one of the co-investigated, considered symptomatic of the executive phase of the operation;
• certain preparatory activities relating to the transport of the narcotic substance.

These elements were considered by the Court of Review to be suitable to support, in the precautionary phase, the accusatory hypothesis of a criminal plan aimed at importing narcotic substances into the national territory.

The decision of the Court of Cassation: deficiencies in the evaluation of serious evidence

The Court of Cassation held that the order of the Milan Court of Review had not adequately demonstrated the existence of serious evidence of guilt regarding the alleged importation of narcotic substances.

In particular, the Supreme Court highlighted how the precautionary measure did not clarify in a sufficiently rigorous manner the existence of a concrete, current, and operationally defined agreement aimed at introducing the substance into the national territory.

According to the Court of Cassation, the reasoning of the challenged order did not adequately address some decisive profiles for the verification of the evidentiary framework, including:

• whether the alleged supplier had actual availability of the narcotic substance subject to negotiation;
• whether the substance had already been identified or acquired within a supply circuit;
• whether concrete contacts had been initiated with international suppliers capable of making the operation effectively feasible;
• whether an operational plan had been prepared for the introduction of the drug into the national territory.

In the absence of these elements, the Court observed, it is not possible to consider the existence of serious evidence of participation in international drug trafficking to be adequately demonstrated – not even from a precautionary perspective.

The principle affirmed by the Court of Cassation

The ruling of the Court of Cassation is noteworthy for having clarified a particularly important principle regarding international drug trafficking and the evaluation of serious evidence in the precautionary phase.

The Supreme Court has in fact affirmed that the agreement between several subjects relating to the buying and selling or movement of narcotic substances cannot automatically be qualified as an agreement aimed at their importation into the national territory.

For the purpose of configuring the crime of drug importation, it is necessary that the evidentiary framework allows for the identification with sufficient clarity of:

1. the existence of a criminal project concretely aimed at introducing the substance into the national territory;
2. the carrying out of operational activities capable of making the transfer of the drug to Italy effectively possible;
3. the presence of a criminal program with concrete feasibility, and not reducible to a mere negotiating hypothesis or an still interlocutory phase of the negotiation.

Implications for corporate criminal law

The decision under examination by the Court of Cassation also assumes significant importance in the broader context of corporate criminal law, a sector in which the application of personal precautionary measures can have a particularly serious impact not only on the position of the investigated person, but on the entire organizational structure of the economic activity.

In such contexts, the adoption of a custodial measure against an entrepreneur can lead to particularly significant consequences, such as:

• the paralysis or slowdown of business activity;
• the compromise of commercial and contractual relationships with partners and suppliers;
• significant reputational repercussions in the reference market;
• destabilizing effects on the entire organizational structure of the company.

Precisely for these reasons, the jurisprudence of the Court of Cassation requires that the application of personal precautionary measures be preceded by a particularly rigorous verification of the consistency of the evidentiary framework. The protection of personal liberty requires that recourse to pre-trial detention constitutes an extrema ratio.

Criminal defense of entrepreneurs and precautionary appeals

The decision under examination confirms how, in criminal proceedings involving entrepreneurs and economic operators, the phase of precautionary appeals plays a decisive role.

In proceedings involving entrepreneurs, it is therefore essential to:

• proceed with a critical and systematic analysis of the evidentiary compendium, verifying its logical coherence;
• distinguish precisely between lawful economic activity and criminally relevant conduct;
• verify, with a rigorous method, the actual reliability and relevance of the investigative elements.

Only through a technical defense based on these assumptions is it possible to ensure effective control over the legitimacy of measures restricting personal liberty.
