Italian police and courts: who is who

Italy has several police forces with overlapping powers, and two institutions that visitors constantly confuse: the questura, which is police, and the procura, which is the prosecutor's office. Knowing which is which saves days when you are trying to find someone or work out who is dealing with a case.
The forces
| Force | Nature | Typically deals with |
|---|---|---|
| Polizia di Stato | Civilian national force | Cities, public order, borders, immigration |
| Arma dei Carabinieri | Military status, general jurisdiction | The whole territory, including small towns |
| Guardia di Finanza | Financial and customs police | Tax, customs, financial crime, smuggling |
| Polizia Locale | Municipal | Traffic, local rules, some criminal matters |
| Polizia Penitenziaria | Prisons | Custody and transfers |
The first two have general jurisdiction and either may deal with the same offence. Which one intervened matters practically rather than legally: it tells you which building to go to, and that is the first thing a family needs to know.
The Guardia di Finanza is the one visitors underestimate. It is a police force with full criminal powers, not an inspectorate, and it conducts financial searches, seizures and arrests.
Questura, caserma, procura, tribunale
- Questura. The provincial headquarters of the Polizia di Stato. Also handles residence permits, which is why the name appears in immigration contexts.
- Commissariato. A local police station of the same force.
- Caserma or Stazione dei Carabinieri. The equivalent for the Carabinieri.
- Procura della Repubblica. The prosecutor's office. Not police: this is where the magistrate directing the investigation sits.
- Tribunale. The court. Judges sit here, including the one who holds the validation hearing.
In the first hours after an arrest the person is at a police station or barracks, not at the court and not in prison. That is where to look, and the sequence is in the guide for families.
Prosecutors and judges are both magistrates
This is the structural difference that most surprises readers from common law systems. The prosecutor is not an elected official and not a government lawyer: they are a career magistrate, recruited and governed in the same way as judges, and formally obliged to look for evidence in favour of the person under investigation as well as against.
The judges encountered during an investigation have specific roles. The judge for preliminary investigations decides on precautionary measures, authorises interceptions and rules on applications to close a case. The judge for the preliminary hearing decides whether the case goes to trial. They are different judges, and neither of them tries the case.
Who decides what
| Decision | Who takes it | Note |
|---|---|---|
| Whether to arrest in flagrante | The police | Within the limits set by the code |
| Whether to request a precautionary measure | The prosecutor | Applies to the judge |
| Whether to impose one | The judge for preliminary investigations | And validates the arrest |
| Whether to close the investigation | The prosecutor applies; the judge decides | Injured parties may object |
| Whether the case goes to trial | The judge for the preliminary hearing | Where a preliminary hearing is held |
| Guilt and sentence | The trial court | Single judge, panel, or assize court |
Why this matters when something happens
Because the first thing anyone needs is the right building and the right file number. A family calling prisons on the day of an arrest is calling the wrong places; a person trying to find out about a case by contacting the police is asking an office that no longer holds it.
Once a lawyer is appointed this becomes their problem rather than yours. Before that, knowing which force intervened and where they are based is the single most useful piece of information you can hold.
Frequently asked questions
What is the difference between Carabinieri and Polizia?
Both have general jurisdiction over criminal matters. The Carabinieri have military status and cover the whole territory; the Polizia di Stato is a civilian force concentrated in cities, borders and immigration.
What does the Guardia di Finanza do?
It is a financial and customs police force with full criminal powers, dealing with tax, customs, financial crime and smuggling, including searches, seizures and arrests.
Is the questura the same as the procura?
No. The questura is police headquarters; the procura is the prosecutor's office, where the magistrate directing the investigation sits.
Is the Italian prosecutor a politician?
No. Prosecutors are career magistrates recruited and governed like judges, and are formally required to seek evidence in favour of the person under investigation as well as against.
