How Italian Magistrate Investigations Work: An Explainer for Newsroom Readers
A prosecutor in Rome signs a request to send a businessman to trial. Within hours the document is circulating online, the man's photograph is everywhere, and the comment sections have already reached a verdict. What actually happened that morning is narrower, and more interesting, than the coverage suggests: one public official wrote down that he believes a crime was committed, and asked a judge to check. Nothing more, and nothing less.
Italian criminal procedure is not mysterious, but it is dense, and its early stages are designed to be closed. That combination produces a particular kind of reporting error: documents from a preliminary file get treated as findings, and suspects get treated as defendants, and defendants as convicts. This explainer is a map of the machinery, so that the next time a case file lands on your desk you know exactly which gear you are looking at.
The Cast: Who Does What Before Trial
Three figures matter most in the phase before any courtroom appears.
The public prosecutor (pubblico ministero, or PM) works at the Procura della Repubblica. The PM directs the investigation, gives orders to the police — Carabinieri, Polizia di Stato, Guardia di Finanza — and decides where the case goes at the end. Under Article 112 of the Constitution, prosecution is obligatory: a PM cannot decline a case because it is politically inconvenient or expensive. The only exit is a legally defined one, usually a request to archive the file.
The investigating judge (giudice per le indagini preliminari, GIP) is not the prosecutor's partner. The GIP authorises wiretaps, signs search and seizure decrees, decides on pre-trial detention, and handles early evidence-taking when a witness may not survive to trial. Every intrusive act by the prosecution needs this judge's signature.
The preliminary hearing judge (giudice dell'udienza preliminare, GUP) takes over at the end of the investigation and answers one question: is there enough here to justify a trial? A GUP who says no dismisses the case. A GUP who says yes issues the decree that opens the trial.
Terminology carries meaning, and Italian law is unusually precise about it. During the investigation, a person is an indagato — a suspect, formally under investigation. Only after the case is sent to trial does the person become an imputato, a defendant. Using the wrong word is not pedantry; it is an assertion about a procedural stage that may not have arrived.
How an Investigation Actually Runs
The sequence is fairly consistent, though timings and practices vary between prosecutors' offices.
- Registration. A report of a crime — a complaint, a police report, a hospital alert — is entered in the register of crime reports. The case gets a number. From this point the clock runs.
- Investigative acts. Questioning of witnesses and suspects, searches, seizures, forensic analysis, bank-record requests, wiretaps (with judicial authorisation). Defence lawyers can file briefs and, for certain acts, attend or access materials.
- Notice to the suspect. When the prosecutor intends to carry out an act requiring a defence lawyer to be present, the suspect receives a formal information notice (informazione di garanzia). Historically this has been misdescribed in the press as a "warning of guilt". It is a summons to participate, not a finding.
- The deadline. Preliminary investigations normally run six months, extendable by the GIP up to eighteen months, with a longer ceiling for a closed list of serious offences. If the file is not closed in time, the investigation cannot simply drift.
- The closing notice. Before deciding, the prosecutor must serve a notice that the investigation is concluded. At that point the suspect's lawyer can inspect the file, file arguments, and ask for further evidence to be gathered.
- The fork. The prosecutor either requests dismissal (archiviazione) or requests indictment. Indictment leads to the preliminary hearing; the case is then either sent to trial or dismissed. In parallel, the parties may choose an abbreviated trial or a negotiated sentence, both of which produce outcomes that look different from a full trial and should be described as such.
What a Document Proves, and What It Only Asserts
The single most useful habit in reading an Italian case file is to ask what standard of proof the document applies.
For pre-trial detention, the threshold is gravi indizi di colpevolezza — serious circumstantial indications of guilt. That is a real bar, but it is lower than the trial standard, which is proof beyond reasonable doubt. A custody order therefore tells you that a judge found serious indications plus a specific risk — of flight, of tampering with evidence, of repeating the offence. It does not tell you that anyone has been convicted of anything.
A prosecutor's request for indictment is a prosecutor's opinion, written in the form the law requires. A wiretap transcript proves that a conversation was intercepted and recorded, subject to authentication; it does not prove that the interpretation given to a sentence in the prosecutors' summary is the only one available. A seized document proves it exists and says what it says.
A useful desk rule: replace "the documents show" with "the prosecutors allege, citing these documents". If the sentence still works, you have written it accurately.
Why Custody Orders Deserve Slow Reading
Orders that impose pre-trial detention are long, and they are usually the source of the most dramatic quotations in a case. They are also curated. An investigating judge summarises selected material — transcripts, statements, seized papers — to justify a decision taken in a hurry, on a file assembled by one side. The defence may not yet have filed its response, and if it has, that response is often in a separate document that journalists never receive.
Two things follow. First, defence counsel has a right to challenge the order before a dedicated review court, and later before the Court of Cassation; those challenges are part of the record and worth checking before publication. Second, the excerpts chosen by a judge are not a representative sample of the file. A wiretap in which a suspect says something seemingly damning may sit alongside hours of tape in which he says something mundane, or exculpatory.
Dismissal Is Not an Acquittal
Italian cases end in several different ways, and the differences matter enormously to the people involved.
Archiviazione is a decision not to proceed. It can rest on a finding that the reported fact never happened, that the perpetrator is unknown, that the evidence is too thin, that the conduct is not a crime, or that time has run out. Only some of those resemble a finding of innocence. An acquittal after trial (proscioglimento) is a judicial determination on the merits, delivered with a stated formula — the fact does not exist, the defendant did not commit it, the fact is not an offence.
Prescription (prescrizione) quietly ends cases regardless of what the evidence showed, and its rules have been amended repeatedly. A case that dies of time tells you nothing about guilt, and reporting it as vindication is as inaccurate as reporting it as escape.
A Practical Checklist for a Case File
- Name the document. Is it a registration, an information notice, a closing notice, a prosecutor's request, a custody order, a dismissal request, a judgment? Each sits at a different point on the timeline.
- Date it, and ask what came after. A 2019 custody order says nothing about where the case stands now.
- Identify the standard of proof the document applies, and say so in your copy.
- Attribute every allegation to the person or office making it.
- Look for the defence. If the file contains no response, say that the person has not had the chance to respond, and ask them.
- Check whether the case is still live before describing anyone as "under investigation".
- Watch the verbs. "Accused", "alleged", "charged" and "convicted" are not interchangeable, in English or in Italian.
Working Rules for Anyone Reporting on a Case
Follow the case forward. Diaries get lost and follow-ups get skipped, but an indictment request reported once and a dismissal reported never leaves a permanent, false impression. Set a reminder to check the file in three months, six months, a year.
Be careful with leaked material. Italian investigations are covered by a secrecy rule, and publishing a leaked act is a different editorial act from publishing a court judgment. Ask who benefits from the leak, and whether the same document was given to other outlets — that pattern is itself information.
Finally, remember that for the person named, the difference between an investigation and a conviction is most of their life. That is not a reason to soften accurate reporting. It is a reason to be exact about which stage of the machinery you are describing, and to write about the process as precisely as you write about the people inside it. On questions of law or an individual's position, direct readers to a qualified Italian lawyer rather than to a summary — including this one.
