Italy's top anti-mafia prosecutor has sounded the alarm on a recent overhaul of wiretapping law, warning that new restrictions are actively obstructing investigations into organized crime and terrorism by shielding the white-collar professionals who keep criminal syndicates afloat.
Why This Matters
• White-collar immunity: The reform effectively blocks prosecutors from using wiretaps collected in one case to pursue corruption, tax fraud, or financial crimes uncovered in separate investigations—crimes typically committed by accountants, lawyers, and business executives who serve mafia organizations.
• Terrorism blind spots: Investigators can no longer tap communications in linked cases to track recruitment, radicalization, or support networks for extremist groups, including minors being drawn into violent organizations.
• Ballooning costs: Prosecutors are now forced to duplicate wiretap orders across multiple case files to avoid losing evidence, driving up expenses and straining police resources.
The Law Behind the Controversy
On April 24, 2025, Italy's Law 47/2025—known colloquially as the Zanettin Law—took effect, imposing a strict 45-day cap on wiretap operations for most crimes. Extensions require prosecutors to demonstrate "absolute indispensability" backed by "specific and concrete evidence," a higher burden than the previous standard. Although the law carved out an exemption for mafia and terrorism investigations, allowing longer durations and a lighter evidentiary threshold, it simultaneously introduced sweeping limits on cross-case use of intercepted communications.
Under the new regime, if a wiretap authorized for a mafia probe captures evidence of a separate economic crime—say, a kickback scheme involving a public official or a corporate tax dodge—prosecutors can deploy that material in a new case only if the offense carries the possibility of mandatory arrest in flagrante delicto. The vast majority of white-collar offenses, including corruption, embezzlement, and fraudulent invoicing, fall outside that narrow window.
The restriction builds on an earlier package, Law 114/2024 (the so-called Nordio Law), which entered into force in August 2024. That statute prioritized privacy protections, banning publication of wiretap transcripts unless a judge cites them in a ruling or they are introduced at trial. It also mandated the redaction of third-party data from court filings and barred the acquisition of attorney-client communications absent a showing that they constitute the corpus delicti. While the Nordio Law aimed to shield bystanders and safeguard defense privilege, critics argue the cumulative effect—when layered with the Zanettin Law—has tilted the balance decisively against investigative efficacy.
A Prosecutor's Dire Warning
In a letter dated May 4, 2026, and addressed to Justice Minister Carlo Nordio, Interior Minister Matteo Piantedosi, and Chiara Colosimo, chair of the parliamentary Anti-Mafia Commission, Giovanni Melillo—who heads the Italy National Anti-Mafia and Anti-Terrorism Directorate—described the reform's impact as "extremely grave and alarming." He argued that the statute engineers an "objective retreat" in the state's capacity to dismantle organized crime and prevent terrorist acts.
Melillo pointed to a structural vulnerability: modern mafia operations depend not on violence alone but on networks of complicit professionals—notaries who launder real estate, accountants who sanitize illicit earnings, lawyers who broker deals. "Almost all white-collar crimes committed by those who collaborate with criminal organizations remain immune from the use of intercepts gathered in other proceedings," he wrote, "resulting in a substantial retreat in the effectiveness of action against such phenomena."
The prosecutor also flagged a blind spot in counterterrorism. The new law "prohibits recourse to intercepts ordered in connected proceedings to ascertain conduct such as participation in a subversive association, assistance to members, or incitement and apology for crimes with terrorist purposes," Melillo explained. Those offenses underpin the recruitment dynamics—often targeting minors—that fuel extremist networks. By walling off such evidence, the statute hampers efforts to map and disrupt radicalization pathways before violence occurs.
Impact on Expats, Residents, and Investors
For foreign nationals living in Italy and investors weighing exposure to Italian markets, the reform introduces a zone of regulatory opacity. Because prosecutors can no longer efficiently trace financial flows across multiple case files, shell companies and offshore structures may enjoy a practical immunity from scrutiny. The risk is acute in sectors with historical mafia penetration—construction, hospitality, waste management, and public procurement—where foreign capital is often deployed through local partners.
Expats with businesses in Italy should take note: the law does not reduce the universe of conduct that is illegal, but it does make detection and prosecution less likely when the wrongdoing surfaces tangentially in an unrelated investigation. Compliance officers and in-house counsel may need to strengthen internal audit protocols, given that external enforcement is now more porous.
From a macro perspective, the reform could depress Italy's Financial Action Task Force (FATF) ratings for anti-money-laundering effectiveness, potentially complicating cross-border banking relationships and raising due-diligence hurdles for multinational firms operating in the country.
The Cost of Privacy: Budget and Bureaucracy
Melillo also highlighted an unintended fiscal consequence. To sidestep the "inevitable evidentiary dispersion," Italy's district prosecutors' offices are now compelled to authorize identical wiretap operations in each separate case file. If a single organized-crime probe spawns five related investigations, each must carry its own tap order, multiplying costs and diverting police resources that could otherwise be deployed in the field.
The Italy Ministry of Justice has yet to publish updated expenditure figures, but preliminary estimates suggest the duplication requirement could add millions of euros annually to the investigative budget, with no corresponding gain in evidence quality. The reform also defers until 2026 the rollout of a centralized digital infrastructure for inter-district wiretap coordination, meaning prosecutors will operate under the new constraints without the technical tools originally envisioned to mitigate them.
Europe's Wiretap Patchwork
Italy's pivot toward stricter wiretap rules places it in selective company within the European Union. Most member states already impose judicial oversight and proportionality tests, in line with the General Data Protection Regulation (GDPR) and the Law Enforcement Directive (LED), but national laws diverge sharply on consent and cross-case use.
In Germany, recording a conversation without all-party consent is a criminal offense under § 201 of the Penal Code. France and Spain likewise require blanket consent, though both carve out exceptions for judicial wiretaps authorized by a magistrate. By contrast, the Netherlands, Sweden, Finland, Ireland, and Poland permit one-party consent for personal recordings, and their prosecutors enjoy broader latitude to introduce evidence obtained in tangential investigations, subject to judicial review.
The Court of Justice of the European Union (CJEU) has consistently ruled that mass data retention violates the Charter of Fundamental Rights, but it has upheld targeted surveillance when necessary and proportionate. Italy's new framework nominally respects that standard—wiretaps still require judicial authorization—but by fragmenting the evidentiary chain across multiple cases, it may inadvertently encourage more pervasive, duplicative surveillance to compensate for reduced utility.
What Comes Next
Melillo's letter arrives as Italy prepares for a broader political reckoning over judicial reform. In March 2026, voters narrowly approved a referendum on the separation of prosecutorial and judicial careers, a measure Melillo publicly opposed on the grounds it would "condition delicate investigations" into political corruption and financial crime. That structural shift, combined with the wiretap restrictions, signals a legislative environment increasingly skeptical of prosecutorial discretion.
Whether the government will revisit the Zanettin Law remains unclear. Minister Nordio, a former magistrate who championed privacy safeguards, has defended the reform as a necessary corrective to decades of media leaks and reputational damage inflicted by published wiretaps. Interior Minister Piantedosi has yet to comment publicly on Melillo's letter, and Chiara Colosimo's Anti-Mafia Commission has scheduled hearings for later this month but has not announced a timeline for potential amendments.
For now, Italy's prosecutors face a paradox: the state has granted them longer wiretap windows for mafia and terrorism cases, yet constrained their ability to act on what those wiretaps reveal. In Melillo's calculus, the result is a net loss—a legal architecture that privileges procedural formality over investigative reality, and that may ultimately serve the interests of the very networks it purports to dismantle.
