Overview
The Argentine Republic (República Argentina) has no bilateral extradition treaty with the Federal Republic of Germany. Argentina is neither a contracting state of the European Convention on Extradition (ECE) nor an EU member; the European Arrest Warrant does not apply. Extradition relations are therefore assessed on a non-treaty basis — on the German side under Sections 1 ff. IRG, and on the Argentine side under the Act on International Cooperation in Criminal Matters (Ley 24.767 de Cooperación Internacional en Materia Penal, in force since January 1997). This corresponds to the country guidance in the Guidelines on Relations with Foreign Countries in Criminal Matters (RiVASt): "Extradition relations are conducted on a non-treaty basis."
In practice, extradition relations between Germany and Argentina are limited in number but by no means insignificant. Argentina has one of the largest communities of German descent in Latin America, together with close personal and economic ties to the German-speaking world; requests accordingly occur in both directions. In substance, ordinary criminal allegations predominate today — economic, property and narcotics offenses, money laundering, and tax and currency offenses. Historically, Argentina was at the same time a country of refuge for Nazi perpetrators; the reckoning with that legacy is still recalled today by cases such as the abduction of Adolf Eichmann by the Mossad in 1960 (a formal extradition had failed under Argentine practice at the time) and the extradition of Erich Priebke to Italy in 1995.
The defense in Argentina cases follows a multi-stage review pattern: the non-treaty extradition requirements under the IRG, reciprocity (Section 5 IRG), dual criminality (Section 3 IRG) and — as a regularly decisive argument in German case law — Article 3 ECHR in conjunction with Section 73 sentence 1 IRG concerning the documented desolate detention conditions in the Argentine penal system. The death penalty, by contrast, has been entirely abolished and does not constitute a separate bar.
Legal basis
In the absence of an agreement under international law, the Act on International Mutual Legal Assistance in Criminal Matters (IRG) of 23 Dec 1982 applies directly on the German side. Non-treaty extradition requires, under Section 5 IRG, an assurance of reciprocity from the requesting state; under Section 3 IRG, dual criminality is required (the offense must, under German law, carry a maximum penalty of more than one year's imprisonment, and for enforcement a remaining sentence of at least four months). For non-treaty relations with Argentina, the Higher Regional Court of Dresden has further clarified that the time limits for submission under Section 16(2) IRG (three months from arrest) also apply where the Argentine side provides for shorter internal time limits; the principle of reciprocity does not shorten the limits in this respect (OLG Dresden, OLGAusl 53/14).
For German citizens, extradition to Argentina is excluded under Article 16(2) of the Basic Law; the facilitation under Section 80 IRG applies only to extraditions to EU member states. This bar also applies to German-Argentine dual nationals (cf. BVerfGE 113, 273 — European Arrest Warrant I); multiple nationality has been generally permissible without a retention permit since the Citizenship Modernization Act of 27 June 2024. For persons holding exclusively Argentine or third-country nationality, extradition under Sections 2 ff. IRG is, by contrast, in principle possible.
On the Argentine side, the Ley 24.767 governs; it structures the extradition procedure with the involvement of all three branches of government and safeguards the requested person's fundamental rights at every stage of the procedure. Substantive criminal law is based on the Código Penal de la Nación. The central authority in extradition relations is the Argentine Ministry of Foreign Affairs in coordination with the Ministry of Justice; the judicial decision falls to the federal judiciary, in the last instance to the Supreme Court of Justice (Corte Suprema de Justicia de la Nación). On the German side, the Higher Regional Courts decide on admissibility (Sections 13 ff. IRG); the granting decision is made by the General Public Prosecutor's Offices, and in matters of principle and of foreign-policy significance by the Federal Office of Justice in agreement with the Federal Foreign Office.
Country-specific issues in Argentina
Death penalty — entirely abolished: Argentina abolished the death penalty for ordinary offenses as early as 1984 and for all offenses in 2008 (repeal of the military criminal code). In September 2008, Argentina ratified the Second Optional Protocol to the International Covenant on Civil and Political Rights (ICCPR) as well as the Protocol to the American Convention on Human Rights to Abolish the Death Penalty; given the constitutional rank of international treaties since the 1994 constitutional reform, abolition is practically irreversible. A bar under Section 8 IRG therefore does not exist — this noticeably eases the extradition procedure compared with states that retain the death penalty.
Rule of law — functioning, but with structural deficiencies: Argentina is a constitutional democracy with a fundamentally independent judiciary and well-developed procedural guarantees. International observers (the US State Department, Human Rights Watch), however, record persistent deficiencies: excessively long proceedings, extensive pre-trial detention, susceptibility to corruption and a chronically overloaded penal system. A substantial proportion of detainees are not serving a final sentence but are held in (sometimes years-long) pre-trial detention; in some places, for lack of detention space, arrested persons are unlawfully held in police stations for long periods. Unlike in authoritarian states, the central concern is therefore not the political instrumentalization of criminal law, but the question of whether the concrete treatment of the requested person after surrender meets the requirements of Article 3 ECHR. There is no systematic persecution on political, religious or ideological grounds, so that Section 6(2) IRG is, as a rule, not a decisive consideration; in individual cases — for instance in proceedings with a pronounced political or social dimension, or where there are documented assaults on demonstrators and protest movements — the review under Sections 6, 73 IRG nevertheless remains required.
Community of German descent and historical context: The close ties between the two countries — Argentina is home to one of the largest communities of German descent in Latin America — mean that extradition requests disproportionately often concern persons with German or dual nationality. For them the bar under Article 16(2) of the Basic Law already applies. The historical finding that Argentina was a country of refuge for Nazi perpetrators in the post-war period and refused extraditions at the time (Eichmann, Mengele; Priebke was not transferred to Italy until 1995) has no direct bearing on today's rule-of-law-based procedure, but it still shapes public awareness of German-Argentine mutual legal assistance.
Economic, drug and currency offenses as the practical focus: The requests that are typical today concern organized crime, drug trafficking (Argentina is a transit country for cocaine from the Andean states), money laundering, and economic, tax and currency offenses against the backdrop of recurring currency and capital controls. Here, dual criminality must be carefully reviewed by way of mirror-image analysis: in particular, purely foreign-exchange or fiscal offenses without a German counterpart may stand in the way of extradition (Section 3 IRG; cf. Section 7 IRG for fiscal offenses).
Interpol: An arrest frequently takes place not only upon a formal request but already on the basis of an Argentine Interpol alert (Red Notice or diffusion). Even without the political abuse typical of authoritarian states, it must be reviewed early whether the alert meets the requirements; where there are doubts, a deletion request before the Commission for the Control of INTERPOL's Files (CCF) as well as a protective brief with the Federal Criminal Police Office (BKA) and the Federal Office of Justice are available.
Detention conditions and the human-rights review
The Argentine penal system is documented by numerous independent sources (the US State Department Human Rights Report, Human Rights Watch, the UN Committee against Torture, and the national penitentiary ombudsman's office Procuración Penitenciaria de la Nación) as structurally overloaded and in part in violation of human rights. The central issues are massive overcrowding (around 130 % of official capacity nationwide, at the highest incarceration rate in the country's history), inadequate nutrition, deficient medical care, and substandard sanitary, heating and ventilation conditions. Added to this are documented allegations of torture and ill-treatment (several hundred registered complaints per year in the federal system), deaths in custody, and the unlawful long-term holding of detainees in police stations. A distinction must be drawn between the federal system (Servicio Penitenciario Federal) and the in part still more severely overloaded provincial facilities, in particular those of the populous Province of Buenos Aires; the occupancy and ill-treatment situation varies considerably, so that what matters in the extradition procedure is always the facility specifically envisaged. In November 2025, the UN Committee against Torture again addressed assaults and detention conditions in the state report.
This situation has already been reflected in German extradition case law: in proceedings concerning extradition to Argentina (OLGAusl 53/14), the Higher Regional Court of Dresden had to assess the desolate detention conditions — extreme overcrowding in the Villa Devoto facility in Buenos Aires and comparably problematic conditions in other provinces were reported — against the standard of Article 3 ECHR. A general government declaration that merely reproduces the theoretical legal position, without containing a concrete, facility-specific and verifiable guarantee, does not meet the requirements of a reliable assurance.
It follows that the decisive standard of review is this: in an extradition to Argentina, the review developed for Article 3 ECHR / Article 4 of the EU Charter (Aranyosi/Căldăraru, ECJ C-404/15 and C-659/15 PPU — to be applied as a standard even outside the European Arrest Warrant) is regularly the decisive lever. What is required is a concrete, facility-specific and monitorable assurance naming the facility and providing a verifiable monitoring mechanism — for instance through the German Embassy in Buenos Aires. Consular assistance is governed by the Vienna Convention on Consular Relations (VCCR) of 24 Apr 1963, to which both states are party; for German or German-Argentine nationals, unimpeded consular access must be secured at an early stage.
Lines of defense
The defense in Argentina extradition proceedings has good prospects of success where the case is structured by counsel at an early stage. Review pattern:
- Section 73 sentence 1 IRG in conjunction with Article 3 ECHR (detention conditions): Regularly the decisive argument. Systematically introduce into the admissibility proceedings the reports of the US State Department, Human Rights Watch, the UN Committee against Torture and the Procuración Penitenciaria on overcrowding, hygiene and violence; build on the OLG Dresden line (Villa Devoto).
- Diplomatic assurance — quality is what counts: A general government declaration is not sufficient. What must be demanded is a concrete, facility-specific and monitorable assurance naming the facility and providing a monitoring mechanism (German Embassy in Buenos Aires); absent monitorability, the extradition remains inadmissible.
- Article 16(2) of the Basic Law (extradition of Germans): Where the person holds German nationality — including German-Argentine dual nationals — extradition is excluded; Section 80 IRG applies only to the EU.
- Section 3 IRG (dual criminality): Careful mirror-image review, in particular for Argentine currency, tax and economic offenses without a German counterpart; purely fiscal offenses are additionally subject to Section 7 IRG.
- Section 5 IRG (reciprocity): Non-treaty — a formal, reliable assurance of reciprocity is a condition of admissibility.
- Section 16(2) IRG (time limits for submission): In non-treaty relations the three-month time limit runs from arrest; it is not shortened by shorter Argentine domestic time limits (OLG Dresden, OLGAusl 53/14) — raise any failures by the requesting side to meet the deadline.
- Section 11 IRG (rule of specialty): To be secured separately in non-treaty extradition; a concrete enumeration of the granted offenses in the granting decision, with supplementary requests only on renewed consent.
- Section 9 IRG (double jeopardy / ne bis in idem): Where there are parallel investigations in Germany or third states, review the barring effect.
- Sections 6, 73 IRG (political dimension in the individual case): In proceedings with a pronounced political or social background — for instance in connection with protest movements — to be reviewed despite a fundamentally functioning rule of law.
- Interpol/CCF: Where an arrest is based on a Red Notice or diffusion, review the alert against its requirements; file an early CCF deletion request and a protective brief with the BKA and the Federal Office of Justice.
- Constitutional complaint with an urgent application (Section 32 BVerfGG): After the OLG has declared the extradition admissible, the standard remedy where there are violations of fundamental rights (Article 1(1), Article 2(2), Article 25 of the Basic Law in conjunction with Article 3 ECHR); with a carefully prepared detention-conditions challenge, the prospects are not slight.
Legal representation in Argentine 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.
