European Investigation Order (EIO) in Italy

In brief. The European Investigation Order (EIO) is the EU’s single, fast instrument for gathering evidence across Member States. Created by Directive 2014/41/EU and implemented in Italy by D.Lgs. 21 June 2017, no. 108, it replaced the patchwork of rogatory letters with one mutual-recognition mechanism: a judicial authority in one State issues the order, and the authority in another State executes it within strict deadlines. The EIO can require almost any investigative act — hearings, searches, seizures, bank data, interceptions, covert measures. For the defence, the EIO is double-edged: it accelerates the evidence against a client, but it can also be challenged on its own grounds and harnessed to obtain exculpatory proof abroad.

What the EIO is

The European Investigation Order (EIO) is a judicial decision issued by a competent authority of one EU Member State (the issuing State) to have one or more investigative measures carried out in another Member State (the executing State), based on the principle of mutual recognition.

Introduced by Directive 2014/41/EU, the EIO consolidated and replaced most earlier mutual-assistance instruments between participating Member States, including the rogatory-letter regime for evidence gathering. Italy transposed the Directive with D.Lgs. 21 June 2017, no. 108, which governs both the issuing of Italian EIOs and the execution in Italy of EIOs received from other Member States.

The EIO does not apply to Denmark and Ireland, which did not opt in; cooperation with them, and with all non-EU States, continues under classic mutual legal assistance and rogatory letters.

Scope: what an EIO can require

The EIO is deliberately broad. It can cover virtually any investigative measure, including:

• examination of witnesses, suspects and experts, including by videoconference;
• searches and seizures of documents and objects;
• production of bank and financial information and monitoring of accounts;
• interception of telecommunications and other covert investigative techniques;
• gathering of evidence in real time, controlled deliveries and covert investigations;
• temporary transfer of persons held in custody for investigative purposes.

Two features distinguish the EIO from rogatory letters: it operates on standard forms and direct judicial channels (no diplomatic detour), and it runs on fixed deadlines — in principle a decision on recognition within 30 days and execution within 90 days of the decision (art. 12 of the Directive). In Italy, the public prosecutor of the district capital recognises the EIO by reasoned decree within 30 days (60 at most) and executes it within the following 90 days (art. 4 D.Lgs. 108/2017). This is what makes the EIO faster and more predictable than traditional MLA.

Grounds to challenge an EIO

The EIO’s speed does not strip away safeguards. Both the executing authority and the defence have grounds on which an order can be refused, limited or attacked.

Grounds for refusing recognition or execution

Under art. 11 of the Directive and art. 10 of D.Lgs. 108/2017 (postponement: art. 15 of the Directive), the Italian executing authority may refuse or postpone an EIO where, among others:

• there is an immunity or privilege under Italian law, or rules limiting criminal liability relating to freedom of the press;
• execution would harm essential national security interests;
• the conduct is not an offence in Italy and the measure is not available domestically (where dual criminality is required for the measure concerned);
• there is a real risk of breach of fundamental rights (art. 6 and recital 19 of the Directive; EU Charter);
• the ne bis in idem principle applies;
• the measure would not be authorised in a comparable domestic case (the proportionality and availability filter).

Challenges available to the defence

Crucially, art. 14 of the Directive requires that legal remedies equivalent to those available in a comparable domestic case be available against the EIO. In practice the defence can:

• contest the substantive reasons for the investigative measure in the issuing State;
• challenge, in Italy, the recognition decree: the suspect and their lawyer may lodge an objection with the preliminary-investigations judge within 5 days of its communication; for evidentiary seizures, the owner of the seized items may also object, with an appeal to the Court of Cassation (art. 13 D.Lgs. 108/2017). The objection does not suspend execution, so timing is critical;
• raise the proportionality of the measure and its compatibility with fundamental rights;
• attack the usability of evidence obtained where the EIO was issued or executed unlawfully.

Defence strategy

A coherent EIO defence works on both ends of the order at once.

• Map the order early. Identify the issuing and executing States, the measure sought, and which forum hosts the right remedy — the substantive grounds are challenged where the EIO was issued, the execution where it was carried out.
• Press proportionality and dual criminality. For intrusive measures (interceptions, searches, covert techniques), the proportionality and availability test offers real traction.
• Test fundamental-rights compliance. Detention conditions, fair-trial guarantees and data-protection limits can all underpin a refusal or a challenge.
• Attack usability. Where the order was defective, the resulting evidence may be excluded in the Italian trial — the strategic objective in most cases.
• Use the EIO offensively. The defence can prompt the Italian authority to issue an EIO to obtain exculpatory evidence held in another Member State, fast and through judicial channels.
• Coordinate counsel. Because remedies are split across States, the Italian team must work in lockstep with counsel in the issuing/executing State.

How ILA handles EIO matters

ILA acts across the EIO lifecycle: scrutinising orders executed against clients in Italy, challenging defective recognition or execution under D.Lgs. 108/2017, contesting the underlying measure in the issuing State through correspondent counsel, and deploying EIOs to secure exculpatory evidence abroad. The firm’s Italian offices in Naples, Milan and Rome coordinate with an international network so that the two halves of an EIO challenge move together rather than in isolation.

FAQ

How is an EIO different from a rogatory letter? The European Investigation Order (Directive 2014/41/EU, in Italy D.Lgs. 108/2017) is a mutual-recognition instrument used between EU Member States: standard forms, direct judicial channels and fixed deadlines (around 30 days to recognise, 90 to execute). Rogatory letters are the older, slower mutual-assistance tool, now used mainly with non-EU States and with Denmark and Ireland.

Can I challenge an EIO issued against me? Yes. Article 14 of the Directive guarantees legal remedies equivalent to those in a domestic case. The substantive reasons for the measure are challenged in the issuing State, while recognition and execution can be contested in the executing State — in Italy, by objection to the preliminary-investigations judge within 5 days (art. 13 D.Lgs. 108/2017). Defects can also make the resulting evidence unusable.

Can my defence use an EIO to gather evidence in my favour? Yes. The defence can ask the Italian judicial authority to issue an EIO to obtain exculpatory evidence located in another EU Member State — bank records, witness statements, documents — through fast judicial channels, coordinated with local counsel.
