How to draft a wiretapping request under Art. 267 c.p.p. with AI
4 min read · Updated September 2026 · Editorial oversight: Avv. Federico Papa
The richiesta di intercettazione (wiretapping request) is one of the most sensitive acts in criminal investigations, directly impacting the freedom and secrecy of communications. Drafting it requires strict adherence to legal requirements to prevent the collected evidence from being ruled inadmissible.
In brief
The richiesta di intercettazione under Art. 267 of the c.p.p. (Italian Code of Criminal Procedure) is the motion by which the Pubblico Ministero (Public Prosecutor) seeks judicial authorization from the GIP (Judge for Preliminary Investigations). It must demonstrate gravi indizi di reato (serious clues of a crime) and assoluta indispensabilità (absolute necessity) for the investigation. The document must specify the crimes involved, target devices, and the initial duration. Proper drafting is crucial to ensure the usability of evidence and avoid procedural nullity during trial.
The steps
- 1.
Verification of predicate offenses
The first step is ensuring the offense under investigation falls within the categories defined by Art. 266 c.p.p. Not every crime justifies an intercettazione: the request must specify the offense, verifying it is a delitto non colposo (intentional crime) with a maximum penalty exceeding five years or a specifically listed crime such as drug trafficking. edit.legal helps instantly verify the compatibility of the offense with legal thresholds, reducing the risk of inadmissible requests due to a lack of objective requirements.
- 2.
Articulating serious clues of a crime
Unlike misure cautelari personali (personal precautionary measures), an intercettazione requires gravi indizi di reato rather than clues of guilt. The request must analytically present factual elements suggesting the crime's existence. It is essential to avoid boilerplate language, citing specific annotazioni di polizia giudiziaria (police reports), witness statements, or previous investigative results. The reasoning must be independent and specific for each target of the intercettazione, avoiding generic references to the entire case file which could jeopardize the validity of the GIP's authorization decree.
- 3.
Demonstrating absolute indispensability
The Pubblico Ministero must justify why the intercettazione is characterized by assoluta indispensabilità for the continuation of investigations. It is necessary to explain why less invasive means of searching for evidence, such as surveillance or witness examinations, are insufficient or have already been tried unsuccessfully. This requirement is the core of the proportionality test required by the Corte Edu (ECHR) and Italian constitutional case law. The request must highlight the causal link between the requested interception and the acquisition of evidence otherwise unobtainable, ensuring that the sacrifice of privacy is strictly necessary for the purposes of justice.
- 4.
Technical specification of methods
The request must precisely indicate the subject of the interception: phone numbers, IP addresses, or locations for environmental bugs. If using a captatore informatico (trojan horse), the request must specify the reasons for its use, the locations, if the proceeding concerns criminalità organizzata (organized crime) or terrorism, and the devices to be infected. It is also necessary to indicate the equipment at the Procura della Repubblica (Public Prosecutor's Office), CIT (Centro Intercettazioni Telecomunicazioni), to be used for the operations, unless exceptional urgency or technical unavailability allows for the use of external equipment at the Judicial Police premises, provided specific reasoning is included in the motion.
- 5.
Determining duration and extensions
An intercettazione cannot be indefinite. The request must specify a maximum term of fifteen days, extendable by the GIP via reasoned decree for subsequent fifteen-day periods if the requirements persist. For criminalità organizzata offenses, terms are extended to forty initial days with twenty-day extensions. Monitoring deadlines is essential: a late extension request results in the inadmissibility of results acquired after the previous term expired. edit.legal facilitates the management of investigative calendars, flagging the correct time windows for filing motions to continue the interception activities.

Mistakes to avoid
- Use of boilerplate or per relationem reasoning based on police reports without independent evaluation by the PM.
- Failure to specify the reasons justifying the use of equipment other than the Prosecutor's CIT.
- Requesting wiretapping for crimes that do not meet the penalty thresholds set by Art. 266 c.p.p.
- Failure to specify the necessity of a trojan horse in private dwellings outside of organized crime cases.
Frequently asked questions
What happens if the Public Prosecutor proceeds with an emergency decree?
In urgent cases, where there is a well-founded reason to believe that delay could seriously prejudice the investigation, the Pubblico Ministero (PM) orders the intercettazione via reasoned decree, which must be communicated to the GIP within 24 hours. The GIP must validate it within the following 48 hours, otherwise the results are inadmissible.
Is it possible to intercept conversations between the defendant and their lawyer?
No, Art. 103 c.p.p. prohibits the interception of conversations or communications involving defense lawyers, technical consultants, and their assistants, as well as those between them and their clients, unless the lawyer is personally under investigation for matters unrelated to their professional mandate.
What is the difference between serious clues of a crime and serious clues of guilt?
The gravi indizi di reato required for an intercettazione concern the objective existence of the criminal act, whereas serious clues of guilt, art. 273 c.p.p., concern the probability that a specific person committed the crime. For Art. 267 c.p.p., proof that a crime has been committed is sufficient.
