International arrest warrant in Belgium: the investigating judge first

Direct answer

In Belgium a person arrested on a European warrant or on an extradition request is brought before an investigating judge within the same short period that applies to any arrest there, and that judge decides on detention and informs the person of the request. The chamber that deals with pre-trial matters then rules on execution of the warrant, with an appeal available to the indictment chamber and a further challenge on points of law.

Belgium is a transit country, with international airports, high-speed rail and a major port on the routes between neighbouring states, so a large share of these arrests involve people passing through rather than living there. That has a direct consequence: the person usually has no address, no employment and no ties in Belgium, which is precisely the profile on which detention is ordered, and answering it requires documents rather than assurances.

In brief

  • The investigating judge is the earliest judicial contact and decides on detention while informing the person of what the warrant or request contains.
  • Execution of the warrant is decided by the chamber dealing with pre-trial matters, so the detention decision and the surrender decision are taken by different bodies.
  • An appeal lies to the indictment chamber, and a further challenge on points of law is available to the highest court, which makes the timing of each step important.
  • Consent to surrender shortens the procedure considerably, and its effects cannot be undone afterwards, so it is a decision to take with advice on both sides.
  • Release pending the decision is available in principle but uncommon in surrender proceedings, because the risk of flight is assumed where the person has no local ties.
  • The answer to that assumption is material: an address in Belgium, documents surrendered, reporting conditions, employment, family, and where possible supervision enforced in the country of residence.
  • Belgian proceedings run in one of several national languages depending on the place and the choices made, and that determines who can act, so a request to change the language must be made at the right moment.
  • With warrants issued by Italy the recurring issues are convictions pronounced in absence and the classification of the offence among the categories that dispense with the requirement of punishability in each state.

Why so many of these arrests happen here

Belgium sits on the routes between France, Germany, the Netherlands and the Channel, with two international airports, high-speed rail and a major port. A large proportion of surrender arrests here involve people passing through rather than living in the country.

That has a practical consequence: the person usually has no address, no employment and no ties in Belgium, which is precisely the profile on which detention is ordered. The answer is the same as everywhere — an address, documents, and where possible supervision enforced in the country of residence, described in the guide on pre-trial detention abroad.

The language of the proceedings

Belgian proceedings run in French, Dutch or German depending on the place and the choices made, and this is not a formality: it determines who can act, and a request to change the language has to be made at the right moment. It is one of the first questions to settle.

Several bodies act in succession in a Belgian surrender case, and the table compares what each of them decides.

BodyWhat it decidesWhat follows from the decision
The arresting authorityWhether to act on the warrant or the alert at the border or airport.The person is brought before a judge within the ordinary short period.
The investigating judgeDetention, and the information given to the person.The procedure on execution begins, with the person held or released.
The chamber dealing with pre-trial mattersWhether the warrant is to be executed.Surrender is ordered or refused, subject to appeal.
The indictment chamberThe appeal against that decision.The decision is confirmed, varied or set aside.
The highest courtPoints of law arising from the proceedings.The matter is remitted or the decision becomes final.

Where Italy is the other end

Belgium executes Italian warrants regularly, and the recurring issues are convictions in absence and the classification of the offence in the categories that dispense with dual criminality. Both are answered from the Italian file, which is the Italian side of the work.

The Belgian domestic framework is in the guide for Belgium and the surrender framework in the guide on the European Arrest Warrant.

Frequently asked questions

Who decides on surrender in Belgium?

The investigating judge first, on detention, and then the pre-trial chamber on execution of the warrant, with appeal to the indictment chamber.

How long before I see a judge?

Forty-eight hours, the same rule that applies to any arrest in Belgium.

Why am I detained if I was only passing through?

Precisely because of that: no address, no employment and no ties in Belgium is the profile on which detention is ordered. It is answerable with documents.

Which language will the case be in?

French, Dutch or German depending on the place and the choices made. It determines who can act and should be settled at the outset.

If an arrest has happened in Belgium

Forty-eight hours to the investigating judge, and the language of the proceedings decided at the start. First contact is free and covered by professional privilege, at any hour.

Choices that fall in the hours after a Belgian arrest

The earliest choice is whether to speak. Officers will ask for an account, and a person arrested at an airport or on a border crossing often has little idea why. What you say is recorded and compared with what you say later. Waiting for a lawyer may lengthen the day and seem less cooperative; speaking costs you control over a statement that cannot be withdrawn. Because the arrest leads quickly to an investigating judge, the pressure to say something early is strong.

The next choice is about consent. In a surrender case, a person may agree to be handed over, and that shortens the process. It also gives up arguments, and an agreement given without understanding what is being surrendered cannot easily be reversed. Refusing consent preserves arguments and lengthens the wait. The decision depends on what the warrant says, what grounds exist to resist and how long the person is willing to remain in custody, and it should not be taken without a lawyer who has read the warrant.

A further choice concerns the lawyer. You are entitled to one and to an interpreter, and both can be provided. The lawyer provided may meet you only briefly before the hearing. Appointing your own means someone outside must find, brief and pay a Belgian lawyer while managing everything else. The trade is between a convenient lawyer and a prepared one.

Last, there is the question of the language of the proceedings. If the person is entitled to a particular language, say so at once and ask for the right interpreter. Choose a single person at home to relay messages and ask everyone else to wait.

The profile of someone arrested in transit drives the detention decision, and the table pairs each assumption with the material that answers it.

Assumption madeMaterial that answers it
The person has nowhere to stay in BelgiumA documented address, with the agreement of whoever provides it.
The person will travel on and disappearIdentity documents surrendered, with a reporting condition offered.
There is no employment holding the person in placeA contract or written confirmation from an employer, in Belgium or at home.

Who reaches this page and what they are holding

A family has had a short call to say that a relative has been arrested in Belgium on a warrant. The call came from the airport, from a border post or from a friend, and nobody knows whether the warrant is Italian, Belgian or from another country. They want to know what happens next and who decides.

Another reader is a person who was stopped while passing through. Belgium is a frequent transit point, and many people are arrested at borders and airports on journeys that had nothing to do with the country, discovering only then that a warrant or an alert exists. The shock is that the proceedings concern events far away, sometimes long ago.

A further reader is someone who lives in Belgium and has been told that Italy has asked for their surrender, or who fears it will. For this reader the question is what the Belgian court will examine, what arguments exist and how long the process can take. The Italian side of the file matters just as much as the Belgian one, and the warrant itself needs reading line by line.

What they all need is orientation: the arrest leads to an investigating judge, then to a chamber that decides on execution, with appeal available. Each stage has its own rules and its own opportunities, and nothing said or signed in the meantime should be careless. The sections below explain what changes in daily life, what to gather, what to avoid and how the studio works.

What a Belgian arrest changes at home and at work

The immediate effect is that the person is gone. A detainee cannot answer calls, open email or move money, and people who depend on that person notice within hours. A colleague waiting in a meeting, a hotel expecting a guest, a family that has not heard since morning: each fills the silence with explanations of its own, and some will be wrong.

For a traveller, the journey is over. Flights and connections are lost, a car or luggage may be left where it cannot be reached, and a phone or laptop may be taken. Business trips collapse and the explanation to colleagues has to be short and true: delayed by a legal matter, with a lawyer dealing with it.

For a resident of Belgium or someone working there, the effects spread. An employer may suspend work. A landlord or bank may react to the word arrest as if a verdict had been reached. Dependants have to manage without a signature, a car or an income for as long as the case lasts. Make a plain list for whoever acts at home: bills, appointments, keys, passwords, medicines and anything with a date.

The decision on execution brings further change. If the warrant is executed, the person is handed over to the requesting state, which means a move, new proceedings and often a new language. If it is refused, the person is released. In between, the process of appeal can take weeks, and families should plan for a long period of uncertainty rather than a quick resolution.

Things to avoid, and why

Most damage in these cases is done by people trying to help themselves. Avoid the following.

  • Do not sign what you cannot read. A signature is taken as agreement to the text, whatever was said aloud.
  • Do not consent to surrender without advice. It shortens the process and gives up arguments that may not return.
  • Do not talk about the case with officers, interpreters or other detainees. None of them owes you confidentiality.
  • Do not discuss the facts on calls or visits with relatives. Conversations may be monitored and relatives questioned later.
  • Do not post or message on social media or in group chats. A sentence meant to reassure friends becomes evidence.
  • Do not delete anything from phones, email or cloud accounts. Removal looks like concealment.
  • Do not assume the case is about Belgium. It usually concerns another country, and what you say about it will travel there.
  • Do not change your account between hearings without advice. Inconsistency hurts more than silence.

Each of these keeps your options open until a defender who has seen the warrant can advise you.

If you have already done one of these things, do not panic and do not try to repair it yourself. Tell your lawyer exactly what happened, in plain words and without softening it, so that the defence can take it into account before anyone else raises it. Concealing a mistake is worse than the mistake.

What to gather for your lawyer

A lawyer can only argue from what exists on paper. Collect what you can, photograph rather than move originals and keep copies in more than one place.

  • Passport or identity card and any residence or work papers, scanned in full.
  • The time and place of arrest as exactly as you know them, because the limit on how long you may be held before the investigating judge is counted from that moment.
  • Every document you were given, in its original language, photographed whole. In particular, any copy of the warrant or alert, because the grounds for resisting depend on its text.
  • The names of officers and interpreters you dealt with, what was said about your rights, and whether you asked for a lawyer and when.
  • Evidence of ties: an employment letter, a lease, family records, proof of residence. The judge asks whether you would stay and answer the case.
  • Travel papers: tickets, bookings and messages that explain why you were in Belgium or passing through.
  • Any Italian paper connected to the matter, such as a summons, a judgment or a notice, and whether you have been investigated in Italy before.
  • Papers on any earlier sentence or proceeding linked to the facts, because they may bear on the grounds for execution.
  • Medical information and medicines that custody staff must know about.

Write down what is missing as well. A short honest list lets the lawyer decide where to look first.

Work on a Belgian case runs in parallel with work in Italy, and the table divides it so that neither side is left undone.

TaskWhere it is carried out
The hearings on detention and on executionIn Belgium, by a lawyer admitted there.
The choice of the language of the proceedingsIn Belgium, and raised at the proper moment rather than later.

When Belgium and Italy are both in the case

In a case where Italy is the other end, the warrant comes from Italy and the Belgian judges decide whether to execute it. What they examine is largely the warrant and the person's circumstances, not the underlying case. Your Italian lawyer knows the Italian file and can say what led to the warrant, whether a sentence or a charge lies behind it and what supporting papers exist.

Documents are the first practical difficulty. Italian papers needed in Belgium may need a certified translation and a formal certificate of authenticity, and Belgian papers needed in Italy need the same. Belgium has several languages, and the language of the proceedings may be French, Dutch or German depending on where the case is heard. Ask early which language applies and whether an interpreter has been assigned.

Time and post matter. Offices in the countries keep similar hours, but a request made late in the day is rarely dealt with until the next, and weekends and public holidays stop everything. Post between the countries is too slow for custody matters, so scans go at once and originals follow.

Defenders must speak to each other. The Belgian lawyer knows the investigating judge, the chamber and the appeal route; the Italian lawyer knows the file behind the warrant. They should agree on one account of the facts and divide the work: who speaks to the court, who prepares documents, who talks to the family. The consulate can confirm detention, check conditions and pass messages, but it does not defend you and does not pay for a lawyer.

How the studio takes instructions on a Belgian arrest

Contact the studio by telephone or email using the details on this page. The Rome, Milan and Naples offices take the same calls, and conversations can be held in Italian or English. Say who is detained, where, when, what papers exist and whether the warrant is Italian. If you cannot say, send photographs and we will read them and explain what they are.

The studio does not replace the Belgian defender. A person held in Belgium needs a lawyer who can appear before the investigating judge and the chambers, and the studio works with correspondents there. Our part is to explain to the family and the person held what is happening, to read the warrant and the Italian file, to coordinate with the Belgian defender, to prepare documents that can be translated and certified, and to handle the Italian side of the case.

The appointment is made in writing, signed by the person concerned or, where that is impossible, by a family member on their behalf, and fees are explained before work begins. The initial conversation is about facts and priorities, not reassurance, and we say plainly what depends on the court. Send documents as clear scans labelled by date, with a line saying what each is. We are reachable outside office hours for urgent developments, and we tell the family at each stage what has been done and what must happen next.

Questions to put to a lawyer about a Belgian warrant case

These are the questions people outside the profession rarely think to ask, and the answers shape the weeks ahead.

  • Is the warrant European or an extradition request, and which authority issued it?
  • What does the warrant say, and does it contain everything the law requires?
  • When will I be brought before the investigating judge, and what will the judge decide?
  • Which arguments exist against execution, and which of them fit my circumstances?
  • What would consent change, and can it be withdrawn once given?
  • How does the appeal work, who decides it and how long does it take?
  • What is the language of the proceedings, and how is the interpreter chosen?
  • How will you work with an Italian lawyer, and who decides what is said to each court?
  • What should my family tell my employer, bank and landlord, and what should they avoid?

If an answer is unclear, ask again. A defender who explains the file, the options and the cost of each in words you can repeat to your family is showing you how the case will be run, and you should leave every conversation knowing what comes next and who is responsible for it.

Keep the answers in a notebook with the date beside each, and share them with the relative who is coordinating at home. When the same question gets a different answer on a later day, say so to the lawyer at once, because a changed answer usually means that something in the file has changed.

The words that appear in a Belgian surrender file

A short vocabulary recurs in these cases. Knowing it makes the papers less alarming.

  • Investigating judge. The judge before whom you are brought after arrest. This judge decides on detention and informs you of the warrant, and is your first judicial contact.
  • Pre-trial chamber. The chamber that rules on whether the warrant is executed. In French it is called the chambre du conseil.
  • Indictment chamber. The court to which an appeal against the pre-trial chamber's decision goes.
  • Court of Cassation. The court that hears appeals on points of law only, not on the facts.
  • Consent. Your agreement to be handed over. It shortens the procedure and gives up arguments.
  • Execution of the warrant. The decision to hand you over to the requesting state.
  • European Arrest Warrant. The simplified surrender tool among European states. An extradition request follows a different, slower route.

If a word on your papers is not here, photograph it and ask. A guess from a similar word in another language can mislead.

Keep a short glossary of your own as the papers arrive, with the word, the date on which you met it and the explanation your lawyer gave. Relatives who read the documents later, and any interpreter who is brought in, will then use the same words that you do, and nothing will be lost between languages.

About the lawyer

Most people reach this office in the middle of something they did not plan for: an arrest in another country, a search at dawn, a summons that arrived while they were away from Italy. The first conversation is with Avv. Massimo Romano himself, not with a secretary who takes a message. He is a criminal defence lawyer admitted to plead before the Italian Court of Cassation, and his work has long centred on Italian criminal procedure, European arrest warrants and extradition. On that first call he asks what documents exist, who has seen the person detained, and which authority is involved. No assessment is given before the papers have been read. Afterwards he sets out, in writing, what can be done from Italy and what has to be done where the person is held. Relatives who do not speak Italian are not left translating for themselves: the office speaks with the family in English, by telephone and in writing.

Call the office, or write on WhatsApp if that is easier from abroad. Have to hand the full name of the person involved, the city and country where they are held, and any document already received, even as a photograph.
