Overview
Luxembourg is an EU member state and part of the European Arrest Warrant system. The legal basis is Framework Decision 2002/584/JHA and Sections 78 ff. IRG. Extradition traffic between Germany and Luxembourg is limited in numerical terms but regular, owing to close cross-border economic and transport ties. The Court of Justice of the European Union is seated in Luxembourg — relevant in organizational terms, but not in substantive law for the bilateral extradition relationship.
Structural detention-conditions or rule-of-law problems within the meaning of Aranyosi/Căldăraru or L and P do not exist in the case of Luxembourg. The defense typically concentrates on the presentation of reasonable suspicion, questions of trial in absentia and the formal requirements for the EAW under Section 83a IRG.
Together with Belgium and the Netherlands, Luxembourg belongs to the Benelux mutual-legal-assistance area (Benelux Extradition Convention 1962), which historically established a deeper exchange of mutual legal assistance — but in relation to Germany the EAW Framework Decision remains decisive.
Legal basis
Extradition to Luxembourg is governed primarily by Framework Decision 2002/584/JHA on the European Arrest Warrant, transposed in the Eighth Part of the IRG (Sections 78 ff. IRG). On the Luxembourg side the Loi du 17 mars 2004 relative au mandat d'arrêt européen et aux procédures de remise entre États membres de l'Union européenne applies.
On the German side, the Higher Regional Courts are competent in the admissibility proceedings (Section 29 IRG); the granting decision is made by the General Public Prosecutor's Office (Section 79(2) IRG). On the Luxembourg side, arrest warrants are issued primarily by the juge d'instruction; they may, however, also be issued by the public prosecutor's office (parquet) or by the district court (tribunal d'arrondissement). The court of review is the Cour d'appel.
For German citizens, Article 16(2) of the Basic Law in conjunction with Section 80 IRG applies. The extradition of German citizens to Luxembourg is possible for the purpose of prosecution, but not for the enforcement of a sentence (Section 80(3) IRG). A German citizen who is finally convicted in Luxembourg can be transferred back to Germany for the enforcement of the sentence.
Country-specific issues in Luxembourg
Ground for detention "non-residence": The Luxembourg juge d'instruction frequently finds a ground for detention in the mere fact that the accused is not resident in the Grand Duchy. In extradition proceedings this can become relevant for arrest warrants against German citizens — as a basis for establishing a risk of flight.
Detention review within 10 days: The arrested accused can obtain a detention review within 10 days of arrest; further remedies against pre-trial detention are also available.
Judgments in absentia: Luxembourg recognizes judgments in absentia with two selectable remedies subject to different time limits (15 or 40 days from service). Practical handling requires consultation with local counsel, because the time limits and conditions are subject to change. Section 83 IRG requires an assurance of a retrial.
Detention conditions: Luxembourg operates two prisons (Centre pénitentiaire de Luxembourg Schrassig and Centre pénitentiaire Uerschterhaff). Detention conditions meet European minimum standards; the CPT and the ECtHR have not found any structural deficiencies. The Aranyosi issue practically does not arise in Luxembourg EAW cases.
Clemency procedure: Every convicted person may in principle address a petition for clemency to the Grand Duke — of little practical significance in extradition proceedings.
Detention conditions and the human-rights review
Detention conditions in Luxembourg prisons meet European standards. With the Centre pénitentiaire Schrassig and the newer Centre pénitentiaire Uerschterhaff (opened in 2022, pre-trial detention), Luxembourg operates two modern facilities. CPT reports and ECtHR case law reveal no structural deficiencies.
Cell floor space, sanitary facilities and opportunities for occupation are above the minimum requirements. Medical care and the separation of remand and convicted prisoners are guaranteed.
In defense practice, the Aranyosi review is regularly not applicable in Luxembourg EAW cases. The focus of the defense lies on the formal requirements for the EAW, questions of trial in absentia and the review of the rule of specialty.
Lines of defense
The defense in Luxembourg EAW cases concentrates on formal and procedural points of review:
- Section 83a IRG (minimum particulars): formal review of the presentation of the accusation, the time of the offense, the place of the offense and the legal characterization. Standard: BVerfG 2 BvR 2009/22 of 15 Feb 2023.
- Section 83 IRG (judgments in absentia): for Luxembourg judgments in absentia, an assurance of an effective retrial. Review of the time limits (15/40 days) in coordination with Luxembourg counsel.
- Section 80 IRG (extradition of Germans): review of the connection to the place of the offense and the assurance of return. Extradition for the enforcement of a sentence only with consent.
- Dual criminality: outside the list of offenses, a review on the merits — in practice rarely problematic with Luxembourg, given the extensive harmonization of the law.
- Rule of specialty (Section 83h IRG): limitation of prosecution to the offenses granted.
- Concurrent proceedings / double jeopardy (ne bis in idem): Section 83(1) no. 1 IRG where there are parallel German investigations.
- Proportionality: in minor cases — in particular minor economic or drug offenses — reference to the principle of proportionality (Article 6 TEU, ECJ case law on the proportionate issuance of an EAW).
- Constitutional complaint with an urgent application (Section 32 BVerfGG): rarely promising in Luxembourg cases; exceptionally where there are formal defects under Section 83a IRG.
Legal representation in Luxembourg extradition proceedings
An extradition case is a specialized mutual-legal-assistance procedure that goes beyond classic criminal defense. Engaging a defense lawyer specialized in extradition law at an early stage is regularly decisive — not only after the formal extradition arrest warrant has been issued, but already from the moment of an arrest based on an Interpol notice, an SIS alert or a European Arrest Warrant.
