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

For a request from outside the European Union, Luxembourg's main statute is the Law of 20 June 2001 on extradition. The chambre du conseil of the Cour d'appel (the Court of Appeal's council chamber) gives a reasoned opinion, and the Minister of Justice makes the executive decision; the Minister may grant extradition only on a conforming opinion. A request from another EU Member State normally follows the separate European Arrest Warrant (EAW) procedure, where courts decide surrender and the Minister does not make the final decision.

The first urgent task is to identify which route is being used and what document authorised the arrest. The 45-day limit often mentioned in Luxembourg applies to provisional arrest while the formal extradition request is awaited; it is not a universal maximum for the entire extradition case.

Which legal route applies to a request received in Luxembourg?

Traditional extradition is governed by the Law of 20 June 2001 and any applicable treaty. Under Article 1, the national Act supplies the rules where no treaty applies, subject to special legislation; Article 2 allows extradition subject to reciprocity.

Instrument	When it matters	Practical point
Law of 20 June 2001 on extradition	Traditional extradition, especially from outside the EU	Articles 3 and 7 cover thresholds and nationals; Articles 15 and 18–26 cover the request, arrest, hearing and surrender.
European Convention on Extradition (1957, ETS No. 024)	Where both states are bound, subject to protocols and reservations	The Treaty Office records Luxembourg reservations/declarations concerning default judgments and humanitarian hardship (Article 1), territoriality and reciprocity in the cases covered by Article 7, prior final judgments in a third state (Article 9), transit of nationals (Article 21), and the relationship with other instruments (Article 28). Nationality and integrated-resident questions must also be checked under Article 7 of the 2001 Act and the facts. Check the declaration that applies between both states; do not assume every reservation affects every request.
Law of 17 March 2004 and Framework Decision 2002/584/JHA	European Arrest Warrant between EU Member States	This is judicial surrender with separate deadlines. The Minister-led process and 45-day provisional-arrest rule do not govern an EAW case.
Other treaty or special surrender arrangement	Requests involving a state covered by a separate agreement or a specific international instrument	Before relying on the default Act, counsel should identify the exact instrument, its entry into force for both states, and any reservation or declaration.

For the general sequence, see How Extradition Works; this page covers Luxembourg procedure.

What offence threshold applies under the 2001 Extradition Act?

Article 3 sets a threshold for traditional extradition. For prosecution, the conduct must be punishable under both Luxembourg law and the requesting state's law by a custodial sentence with a maximum of at least one year. For enforcement of a sentence, the foreign sentence imposed must be at least one year and at least six months must remain to be served. These are thresholds under the 2001 Act, not a substitute for checking the applicable treaty or the different EAW rules.

Article 3(4) directs attention to the conduct, not matching offence labels; the request must provide sufficient facts and legal provisions.

Who acts first: the prosecutor, a district-court chamber or an investigating judge?

The district-court chamber does not handle every stage: Luxembourg authorities have different roles at different stages, and the person's location may determine the initial arrest authority.

To enforce a conviction: under Article 18(1), the competent procureur d'État (State Prosecutor) may request arrest on the enforceable conviction.
For prosecution on a foreign warrant: the chambre du conseil of the district court for the person's residence or place found must declare the warrant enforceable.
For provisional arrest pending the request: Article 20(3) assigns the warrant to the investigating judge where the person resides or is found.
For the final opinion: Article 21 names the chambre du conseil de la Cour d'appel, not the district-court chamber.

The official judiciary digest in decision no. 477/20 (8 May 2020) confirms these distinctions. Obtain the actual arrest record and warrant rather than relying on a description such as “an international warrant”.

What must the requesting state send, and what should the defence obtain?

Article 15 requires a written diplomatic request supported by an enforceable conviction or judicial warrant, a description of the conduct with its time and place, relevant legal provisions, identity information including nationality and age, and sentence details where applicable. Article 16 requires the request and supporting documents to be in French or German, or accompanied by a translation into one of those languages. This is a rule for the requesting state’s file; it is separate from the arrested person’s right to understand the documents and proceedings.

Under Article 17, the Minister or the judicial authority may request missing information and set a response deadline. If the reply is insufficient, the request may be refused or the arrest lifted. Counsel should inspect the actual file and translations; an alert or summary is not necessarily the formal request.

An INTERPOL Red Notice or diffusion is not the final extradition decision. Article 20 permits an urgent provisional-arrest request through INTERPOL or another written channel, but the formal request and supporting papers must still follow.

How long can provisional arrest last before the full request arrives?

Article 20 contains a precise rule for provisional arrest while Luxembourg is waiting for the formal request and the Article 15 documents. The arrest may end if the request and supporting papers have not reached Luxembourg within 18 days after arrest, and provisional arrest may never exceed 45 days after arrest. The 45-day ceiling is therefore tied to the provisional stage; it should not be presented as the maximum length of every extradition case.

Article 20(5) permits a release application at any time during the judicial phase. Release is limited to cases involving a serious rights-affecting arrest irregularity, a manifestly unfounded provisional-arrest request, or real guarantees that the person will not evade surrender. A later arrest remains possible if the full request subsequently arrives.

What rights apply immediately after arrest?

Under Article 18 and Article 18-1, the arrested person must receive the relevant documents and a written statement of rights in a language they understand. If a document is not yet available in that language, it may initially be interpreted orally and a written translation must follow when available. Translation of the relevant documents is free, and the person has a right to free interpretation where needed.

The person may contact someone without undue delay. A prosecutor may temporarily restrict that contact only by a reasoned written decision for urgent, specified reasons, and the restriction must be proportionate and strictly limited; the alleged offence alone is not enough. A non-Luxembourg national may also contact and receive visits from consular authorities, although the prosecutor may restrict consular contact where the requesting state’s criminal proceedings require it. The person has a right to chosen or appointed counsel, confidential communication and free interpretation during the extradition process where needed. Anyone who does not understand the proceedings’ language should say so immediately and ask that the interpreter issue be recorded. Do not sign consent simply because a form is presented.

What are the main stages and urgent deadlines?

Stage	Deadline and trigger	Authority and defence action
Provisional arrest before the full request	Request and Article 15 papers should arrive within 18 days; provisional arrest can never exceed 45 days after arrest	An investigating judge issues the provisional warrant. Record the arrest date and check whether the full papers arrived.
Arrest on a formal request	The 2001 Act sets no single overall deadline for the entire traditional-extradition case	The State Prosecutor may request arrest to enforce a conviction; for prosecution, the district-court chamber must make the foreign warrant enforceable.
Request to lift arrest (Article 19)	File within five days from the day after the arrest recorded in the report	File at the Court or prison registry. The Court of Appeal’s council chamber decides urgently and no later than ten days after filing; the person and counsel must be notified of the hearing at least 24 hours in advance. It may lift arrest for a serious rights-affecting irregularity, a manifestly unfounded extradition request or real guarantees against evasion. Cassation is excluded.
Provisional release (Article 20(5))	At any time during the judicial phase	This is separate from Article 19. Address a serious rights-affecting irregularity, a manifestly unfounded provisional-arrest request, or real guarantees against evasion.
Final judicial opinion (Article 21)	At least 48 hours' notice before the hearing; no single overall statutory deadline	The Court of Appeal's council chamber hears the person, counsel and prosecutor, then gives a reasoned opinion.
Minister's decision and possible review	The 2001 Act sets no overall decision deadline; calculate any administrative-court deadline under the applicable procedural rules	The Minister can grant extradition only on a conforming opinion. A possible administrative-court challenge is separate from arrest remedies.

Do not treat the Article 19 request to lift arrest, the Article 20(5) release application and any administrative-court challenge to the Minister's decision as interchangeable remedies.

Who makes the final decision on traditional extradition?

Under Article 21, the chambre du conseil de la Cour d'appel gives a reasoned opinion after a hearing. The hearing is public unless the person requests a closed session; the prosecutor, person and counsel must be summoned at least 48 hours beforehand.

The Minister of Justice decides on the file and opinion. A conforming opinion is necessary for extradition to be granted, but it does not make surrender automatic: the final executive decision belongs to the Minister.

Article 18-1(3) refers to a possible proceeding before the administrative courts against the Minister’s decision. This is separate from an application to lift arrest. The 2001 Act does not state a general filing period for that challenge. Counsel must immediately check admissibility, the applicable deadline, interim relief and any effect on surrender under current procedural law and the specific decision. Do not assume that filing suspends surrender or that the five-day Article 19 deadline applies.

What if the person consents, or more than one state requests them?

Article 23 permits consent at any time from provisional arrest. It must be formal, declared before a competent prosecution magistrate and is irrevocable; an interpreter must assist if the person understands neither French nor German. The file goes to the Minister, who may grant extradition without the ordinary formalities. Obtain advice before declaring consent.

Consent is distinct from waiving a hearing and from the speciality rule. Under Article 22, the receiving state ordinarily may not prosecute or punish the person for earlier offences outside the request, or re-extradite them for earlier offences, without Luxembourg's consent. If several states request the person, Article 24 leaves the choice to the Minister, who considers seriousness and location of offences, request dates, nationality and possible later extradition. Article 25 permits postponement for specified Luxembourg proceedings or sentences.

How does a European Arrest Warrant differ from traditional extradition?

An EAW from another EU Member State is governed by the Law of 17 March 2004 and decided judicially, not by the Minister. The arrested person must appear before an investigating judge within 24 hours; without consent, the district court's chambre du conseil at the place of arrest must decide within 20 days of arrest.

EAW step	Luxembourg rule	What to do
First appearance	Within 24 hours, before the investigating judge	Ask for counsel and a free interpreter; check the issuing authority, purpose and identity details.
First-instance decision	Within 20 days of arrest if there is no consent	The district court's council chamber hears the person and counsel; the person may request a closed hearing.
Appeal	The requested person has five days from notification; the procureur d’État has five days from the order; the procureur général d’État has ten days from the order. The Court of Appeal decides within 20 days after appeal.	Use the correct trigger for each appellant. Article 13(5) excludes cassation.
Transfer after final decision	Ordinarily within ten days, subject to statutory exceptions	Article 14 provides for release if detention continues beyond the applicable deadline, subject to the Act's exceptions.

In judgment no. 133/2024, CAS-2023-00184 (10 October 2024), the Court of Cassation rejected a cassation appeal under Article 13(5), applied through Article 18(1), in an EAW speciality-rule proceeding. This confirms the rule for that EAW route, not for traditional extradition. The judiciary digest also records decision no. 630/19 (9 July 2019): missing the EAW’s 20-day first-instance timetable does not by itself defeat surrender. A detention challenge under Article 9 is a separate question.

Consent to EAW surrender and waiver of the speciality rule are distinct formal choices; under Article 10 of the 2004 Act, each is irrevocable. Before making either choice, obtain legal advice and interpretation if needed. For more on the EAW-specific route, see European Arrest Warrant: arrest, detention and surrender procedure. Do not apply EAW time limits to a request from a non-EU state simply because an INTERPOL alert or international warrant is mentioned.

Can Luxembourg extradite its own nationals?

Article 7(1) prohibits extradition of Luxembourg nationals. Under Article 7(2), refusal may also be possible for a durably resident foreign national with integration or established ties, if extradition is considered inappropriate and the person can be prosecuted in Luxembourg. This is not an automatic exemption: residence, family and social ties, work and domestic prosecutability require evidence.

An EAW is different, so do not automatically apply the 2001 Act’s nationality rule to EU surrender. The 2004 Act has separate conditional rules: for an EAW seeking execution of a sentence, surrender may be refused for a Luxembourg national or certain integrated residents if Luxembourg undertakes to enforce the sentence locally; for an EAW seeking prosecution, surrender may be conditioned on the person’s return to Luxembourg to serve a later sentence. These are not blanket immunity from surrender. If the person has dual nationality or citizenship plus long-term residence, identify the route first. See Extradition and Dual Citizenship.

What should the person and family prepare now?

Obtain the arrest record, rights notice, warrant or judgment, and request file.
Record the arrest time, document dates, language, access to counsel/interpreter and service dates for decisions.
Collect identity and nationality records and, if relevant, residence, work, tax, housing and family evidence.
Give counsel the foreign case number, conduct and dates, conviction details, earlier proceedings and competing requests.
Tell counsel about medical needs and urgent risks. Do not hide, destroy records or influence witnesses.

Hypothetical example: a person is provisionally arrested in Luxembourg after an urgent INTERPOL-based request, but the full diplomatic request has not arrived. Counsel should calculate the 18-day period from the arrest date and the absolute 45-day provisional-arrest limit, check whether the Article 15 documents have arrived, and assess an Article 20(5) release request. If the full request arrives, the case moves to the next procedural stage; the provisional-arrest clock must not be treated as the whole-case deadline.

What does an extradition lawyer do at each stage?

Counsel first identifies the route, checks identity, legal basis, Article 3 threshold, Article 15 documents, arrest authority and deadline triggers, and records translation or document objections.

During detention, counsel assesses the Article 19 and 20(5) applications, prepares evidence and files on time. Before the Court of Appeal chamber, counsel presents the person's position and can request a closed hearing. Detailed refusal grounds and remedy tactics belong to How to Stop Extradition from Luxembourg.

After the Minister's decision, counsel promptly verifies any administrative-court deadline, interim relief and effect on surrender. Alleged torture or other serious human-rights risks require evidence and urgent advice; see Application to the European Court of Human Rights. Do not assume an appeal automatically suspends transfer.

Key points to remember

Traditional extradition involves the arrest-stage authorities, the Court of Appeal's council chamber and the Minister of Justice. The district chamber may make a prosecution warrant enforceable but does not give the final Article 21 opinion. Provisional arrest is limited to 18 days pending the request and no more than 45 days; the separate five-day arrest challenge runs from the day after the arrest recorded in the report. An EAW has its own 24-hour, 20-day and appeal deadlines, with no cassation from the Court of Appeal chamber's decision.

Frequently asked questions

Does a Red Notice mean Luxembourg must extradite me?

No. A notice may be relevant to an urgent provisional-arrest request, but it is not the final extradition decision and does not replace the formal request and supporting documents required by law.

Is 45 days the maximum detention for every extradition case?

No. Article 20(4) sets a maximum of 45 days for provisional arrest while the formal request is awaited. Once the request arrives, the procedural position changes; a release application may be available under the relevant provisions.

Can I change my mind after consenting to traditional extradition?

Article 23 says formal consent is irrevocable. Obtain advice and interpretation before signing or declaring consent. EAW consent and any waiver of the speciality rule are governed by a separate statute and should also be treated as distinct decisions.

Does an appeal automatically stop surrender?

Do not assume that it does. The effect depends on the route, the decision being challenged and any interim measure actually granted. Counsel should verify the applicable rule and seek urgent relief where legally available.
