Extradition from Belgium: How the Procedure Works and What an Extradition Lawyer Does

First identify the procedure: extradition, an EAW, or something else

Ask the police, investigating judge or lawyer for the document that legally authorises detention and for the authority holding the file. An INTERPOL Red Notice or diffusion may alert Belgian authorities to a foreign request, but it does not itself identify the Belgian legal instrument authorising detention or decide whether surrender will occur. In an urgent conventional case, Article 5 of the 1874 Act permits provisional arrest on a Belgian investigating judge’s warrant based on official notice from the requesting state. An EAW is a separate judicial instrument under the 2003 Act.

The country-wide guide How Extradition Works: From Request to Final Decision explains the general international sequence. This page focuses on Belgium’s institutions, legal thresholds and procedural clocks.

Which Belgian court and authority handles conventional extradition?

The label “chambre du conseil / raadkamer of the tribunal de première instance” describes only one stage. Under Article 3 of the 1874 Act, the chambre du conseil (pre-trial chamber of the court of first instance) for the person’s Belgian residence or the place where the person is found makes the foreign arrest warrant or equivalent instrument enforceable. This formal judicial step is not the final executive authorisation to surrender the person.

After detention under an Article 3 instrument and proper service, the Government seeks an opinion from the chambre des mises en accusation (indictment chamber of the court of appeal) for the district where the person was arrested. The prosecution and the person are heard, and counsel may assist. The hearing is public unless the person requests a closed session. Within 15 days after receiving the documents, the chamber sends its reasoned opinion to the Minister of Justice. That deadline concerns the opinion, not the whole case or the final executive decision.

The Act assigns the final power to the Government. The enforceability order, advisory opinion and executive decision are different acts, not interchangeable “extradition judgments.” Record each document’s title, issuing authority and service date, then check the remedy stated for that specific act. Do not use an EAW appeal deadline for a conventional extradition document.

What are the main stages and time limits?

The 2026 amendment to the EAW Act, effective 2 August 2026, removed the former express rules requiring release solely because the 15-day first-instance decision deadline or the 15-day appeal decision deadline had been missed. Those deadlines still matter, but their expiry alone does not trigger the repealed automatic-release provisions. A person may separately seek release under Article 20, and continued detention must be assessed on its facts. In Lanigan (C-237/15 PPU), the Court of Justice held that expiry of the EU decision deadline does not by itself end the procedure or require release; detention must end if its duration becomes excessive.

For conventional extradition, Article 5 also allows the person to request provisional release under the conditions applicable to a Belgian person. The request is submitted to the chambre du conseil. The 40-day rule concerns communication of the foreign warrant after provisional arrest; it is not a universal maximum for all extradition detention. Check the applicable treaty and every separate detention title.

What legal basis and treaty terms should be checked?

As effective from 1 September 2026, Article 1(2) of the 1874 Act uses the new Belgian penalty levels: the conduct must be punishable in Belgium by a level 2 or higher penalty and abroad by a maximum custodial penalty exceeding one year. For enforcement of an imposed sentence, the sentence must be at least one year; a custodial security measure must be indefinite or last at least four months. Under Article 1(3), certain additional acts in a multi-offence request may be included even if they do not individually meet the threshold. Check the charge and the version applicable to the case rather than relying on an older summary.

Article 2 also limits extradition for conduct committed outside the requesting state: subject to reciprocity, Belgian law must permit prosecution of the same conduct committed outside Belgium. Article 7 bars conventional extradition if prosecution or sentence limitation has already expired under Belgian law. Article 4 provides a narrower transit route that may dispense with the Article 3 appellate opinion where the treaty and statutory conditions are met. Transit is not the same as a decision to extradite a person from Belgium.

The Belgian EAW Act also specifies that an incoming warrant must be translated into Dutch, French, German or English (Article 2(6)). If the person does not understand the language of the warrant or its translation, ask counsel to check the translation and the rights-information record; do not assume that a language problem automatically cancels the warrant or stops the clock.

Does Belgian nationality prevent surrender?

For conventional extradition, Article 1 of the 1874 Act concerns a “foreigner,” and Article 6 of the 1957 Convention permits states to refuse extradition of their own nationals. Prove nationality with reliable civil-status documents and check the relevant date and any bilateral treaty clause before treating this as an absolute rule.

An EAW is different: Belgium can surrender its nationals under EU law. For a Belgian national or resident sought for prosecution, Article 8 allows a condition that the person return to Belgium after trial to serve any custodial sentence or measure. It is a possible condition, not an automatic refusal or guaranteed return. For dual nationals, identify every nationality and check the treaty’s definition and legally relevant date; dual nationality alone does not decide the route.

If a third country seeks an EU citizen who is a national of another Member State, check the Court of Justice’s Petruhhin line on information exchange with the state of nationality and a possible EAW. It is not blanket immunity from extradition. Raugevicius concerns the distinct situation of a third-country request to enforce a sentence against a mobile EU citizen who is a national of another Member State, where domestic law allows nationals to serve that sentence at home.

What if there are two requests, or a request and an INTERPOL alert?

If several EU states issue EAWs for one person, Article 29 assigns the choice to the chambre du conseil, after the Federal Prosecutor’s opinion, within 15 days. Article 30 covers a different conflict between an EAW and a third-country extradition request: the Government chooses priority within 30 days after notification by the public prosecutor, taking account of the circumstances and applicable convention. The EAW decision periods in Articles 16–19 begin only after that priority decision. Choosing priority is not itself the final decision to execute an EAW or extradite the person.

Compare any INTERPOL Red Notice or diffusion with the actual Belgian arrest documents. Establish whether the basis is an EAW, a provisional extradition warrant or another domestic warrant, whether the formal request arrived and which authority holds the file. The notice does not replace treaty and statutory steps. For notice data or a challenge before the Commission for the Control of INTERPOL’s Files (CCF), see the separate INTERPOL Red Notice and CCF page.

What does consent change—and what does it not change?

In an EAW case, consent can accelerate the process: under Article 13, the prosecutor decides within 10 days after consent, subject to the investigating judge’s check under Article 14. Consent must be voluntary and informed. It is not the same as waiving speciality, which generally limits prosecution after surrender for earlier offences other than the offence underlying the request, subject to exceptions. Before signing, establish whether the document records consent to surrender, waiver of a hearing or a separate waiver of speciality; the choices are not interchangeable.

In conventional extradition, consent and any simplified route depend on the treaty and Belgian procedure. Do not import EAW deadlines into a third-country case. Transfer, deportation and removal also have different legal bases and safeguards; compare extradition versus EAW surrender and extradition versus deportation if the documents are unclear.

What should an extradition lawyer do at each stage?

At arrest, counsel should obtain the arrest record, warrant, written rights notice and any translation; identify the detention title and calculate each deadline from its legal trigger. Before the hearing, counsel should obtain the file, check identity and documents, arrange interpretation and explain the available choices. In a conventional case, counsel should check the treaty and reservations, Article 3 documents, description of the conduct, nationality, limitation and the sequence of judicial and executive acts. In an EAW case, counsel should calendar the 48-hour appearance, 15-day first-instance decision, 24-hour appeal window and separate handover period; assess conditional release or bail; and check whether a conflict of requests affects when the EAW clock begins.

Before consent or transfer, counsel should explain speciality, any separate waiver, a possible return condition, and the effect of other requests. Cross-border work may require coordination with counsel in the requesting state to obtain reliable records and relevant assurances. A lawyer cannot promise refusal or release. The task is to identify the controlling instrument, protect procedural rights, preserve evidence and calculate deadlines from the correct event.

What should the person and family collect now?

• All police, court, prosecutor, Ministry and foreign-authority documents, including proof of service and the envelope or electronic notice showing when service occurred.
• Passport, identity or residence documents, proof of nationality, usual residence and family links.
• The foreign warrant, indictment, judgment, sentence calculation and translations—or the name of the authority holding them.
• A chronology of arrest, hearings, service of decisions, release requests, consent or waiver statements, and any proposed transfer date.
• Relevant medical records, a trusted family member’s contact details, other warrants, earlier extradition or surrender, and any related Belgian proceedings.

Do not evade arrest, conceal evidence or influence witnesses. Preserve documents and send counsel a complete chronology. A relative abroad can provide scans and dates but should not assume they can file a remedy without the required authority or procedural standing.

A hypothetical example: why the first classification matters

Hypothetical: a Georgian national is stopped at Brussels Airport after an INTERPOL alert tied to a non-EU request. Counsel must establish whether a Belgian investigating judge issued a provisional warrant under Article 5, whether the person has been given communication of the foreign warrant, and when the 40-day period started. If the papers instead show an EAW, the 48-hour judicial appearance and the EAW decision and appeal deadlines apply. Confusing the routes risks missing the correct procedural step.

What do the Belgian and European judgments show?

In Trabelsi v. Belgium (application no. 140/10, 4 September 2014), the European Court of Human Rights (ECtHR) found violations connected with extradition to the United States, the risk of an irreducible life sentence and failure to comply with an interim measure. It is not an unlimited rule for every proposed sentence. In Sanchez-Sanchez v. the United Kingdom (Grand Chamber, application no. 22854/20, 3 November 2022), the Court adopted a two-stage test for extradition before conviction and expressly departed from Trabelsi in that context: first assess whether there is a real risk of life imprisonment without parole; only then examine whether a sentence-review mechanism exists. The full Sanchez-Sanchez judgment is linked in the sources below; the facts and stage of the requesting-state case still matter. A later Chamber judgment, Hayes and Others v. the United Kingdom (1 July 2025, applications nos. 56532/22, 56889/22 and 3739/23), also found no Article 3 violation on its facts despite the alleged risk of mandatory life imprisonment without parole. The Registry’s press release reports the outcome but is not the judgment; this result is fact-specific and does not mean that every such extradition is lawful.

For conventional extradition, a challenge to the advisory opinion and a challenge to the final executive order are different routes. The Court of Cassation and the Council of State may have different roles depending on the act challenged. The forum, scope and deadline must be checked against the exact document served, not borrowed from the EAW appeal rules. Detailed refusal grounds and remedies are covered on How to Stop Extradition from Belgium. An ECtHR application or request for an interim measure is not an automatic appeal or a guaranteed stay; it requires urgent, case-specific assessment.
