Overview
The Republic of Paraguay (República del Paraguay, Guaraní Tetã Paraguái) and the Federal Republic of Germany are linked by a bilateral extradition treaty: the Extradition Treaty between the German Reich and Paraguay of 26 November 1909 (RGBl. 1915 p. 571). This old treaty from the imperial era remains in force in relation to the Federal Republic as successor state and is still listed today as the governing treaty basis in the country section of the Guidelines on Relations with Foreign Countries in Criminal Matters (RiVASt). Paraguay is not a party to the European Convention on Extradition (EuAlÜbk) and is not an EU member; the European Arrest Warrant does not apply.
Where the treaty — now more than a hundred years old and not reflecting today's human-rights standard — contains no provision, the Act on International Mutual Legal Assistance in Criminal Matters (IRG) applies supplementarily (Section 1(3) IRG). In practice, the volume of extradition traffic between Germany and Paraguay is small. The country nevertheless gains relevance through two constellations: first, the large population of German descent together with the German-speaking Mennonite colonies; second, the tri-border area around Ciudad del Este as a hub of cross-border organized crime (drug, weapons, smuggling and money-laundering offenses). Historically, Paraguay was also a refuge for German nationals who had gone into hiding; in the Stroessner era (1954–1989) German requests — for example for the extradition of the Nazi criminal Josef Mengele — were refused. This history makes clear that the practical enforcement of extradition requests always depends on the prevailing political and judicial situation.
The defense in Paraguay constellations follows a multi-stage review grid: the treaty requirements of 1909 and, supplementarily, the IRG; dual criminality (Section 3 IRG); the blocking effect of Article 16(2) of the Basic Law for Germans; and — as a regularly decisive argument — Article 3 ECHR in conjunction with Section 73 sentence 1 IRG concerning the notoriously dire detention conditions in the Paraguayan prison system.
Legal basis
On the German side, the basis of extradition traffic is the bilateral treaty of 1909, supplemented by the IRG of 23 December 1982 (Section 1(3) IRG). Because the old treaty dates from a time before the ECHR and before the Basic Law, its provisions must always be construed in the light of today's constitutional and convention law; the mandatory limits of Sections 6, 8 and 73 IRG and of Articles 1, 2 and 25 of the Basic Law take precedence over any treaty-based duty to extradite. Under Section 3 IRG, dual criminality is required (the offense must carry a maximum penalty of imprisonment of more than one year, or, for enforcement, at least four months of sentence remaining). Of practical significance is the particularity recorded in the country section of the RiVASt that the Paraguayan authorities decide on a German request only once the Federal Government's request is additionally accompanied by a judicial "extradition request" from the court that issued the arrest warrant or imposed the custodial sentence.
For German nationals, extradition to Paraguay is excluded under Article 16(2) of the Basic Law in conjunction with Section 80 IRG; the relaxation in Section 80 IRG applies only to extraditions to EU member states. In view of the large German-Paraguayan dual-national community, this blocking effect is of considerable practical significance and continues to apply to German-Paraguayan dual nationals as well (cf. BVerfGE 113, 273). Multiple nationality has been permissible without a retention permit since the Nationality Modernization Act of 27 June 2024.
On the Paraguayan side, extradition is governed by the Constitution of 1992 and the provisions of the Code of Criminal Procedure (Código Procesal Penal); the central authority in extradition traffic is the Ministry of Justice in coordination with the Ministry of Foreign Affairs, and the judicial review is carried out by the Corte Suprema de Justicia. 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 cases of fundamental or foreign-policy significance by the Federal Office of Justice in agreement with the Federal Foreign Office.
Country-specific issues in Paraguay
Death penalty — fully abolished: Paraguay expressly abolished the death penalty in Article 4 of the Constitution of 1992 ("Queda abolida la pena de muerte"); the last execution dates from 1928. Paraguay also acceded to the Second Optional Protocol to the International Covenant on Civil and Political Rights (ICCPR) aiming at the abolition of the death penalty on 18 August 2003 and has repeatedly supported the UN moratorium resolutions. The bar to extradition under Section 8 IRG is therefore generally not engaged — a significant difference from extradition proceedings to states that carry out executions.
Detention conditions and overcrowding as the central bar: The vast majority of the defense in Paraguay cases is carried by the human-rights-incompatible detention conditions. The Paraguayan prison system is marked by extreme overcrowding, excessive and prolonged pre-trial detention and lethal violence; a share of around two-thirds of pre-trial detainees evidences an excessive use of pre-trial detention that structurally overfills the facilities. This finding is regularly decisive for the admissibility review under Section 73 sentence 1 IRG in conjunction with Article 3 ECHR — details in the following section.
Judicial corruption and rule-of-law deficiencies: Paraguay has for years ranked in the lower field of the relevant corruption indices; the judiciary is regarded as susceptible to political influence and bribery. International reporting (US State Department, Freedom House, Global Initiative against Transnational Organized Crime) documents the entanglement of state bodies with criminal structures, in particular the Brazilian Primeiro Comando da Capital (PCC). In addition, according to the reports, criminal groups use the overcrowded facilities as a space for coordination and recruitment, so that corruption and the reality of detention mutually reinforce each other. Deficiencies in procedural fairness, the presumption of innocence and the length of proceedings are to be examined within the framework of Section 73 sentence 1 IRG (ordre public, the right to a fair trial under Article 6 ECHR).
Tri-border area and organized crime: The region around Ciudad del Este in the tri-border area with Brazil and Argentina is an international hub for drug and weapons trafficking, smuggling, product piracy and money laundering. Extradition requests from this field of offenses must be carefully reviewed as to whether sufficient grounds for reasonable suspicion and a sustainable body of evidence exist, or whether the incriminating evidence rests on statements from a corruption-prone environment. Politically or economically motivated abuse of Interpol alerts (Red Notice, diffusion) can be challenged under Article 3 of the Interpol Constitution before the Commission for the Control of Files (CCF).
Population of German descent and Mennonite colonies: Around 400,000 members of Paraguay's population are of German descent; in addition there are the German-speaking Mennonite colonies in the Chaco (Menno, Fernheim, Neuland with the centers Filadelfia and Loma Plata), where Plautdietsch and standard German are spoken. From this close personal interconnection follows an above-average number of affected persons who are German or dual nationals — for whom the blocking effect of Article 16(2) of the Basic Law (no extradition of Germans to third countries) and consular protection under the Vienna Convention on Consular Relations (VCCR) are of particular practical significance.
Detention conditions and the human-rights review
Detention conditions in the Paraguayan prison system are documented as seriously incompatible with human rights by numerous independent sources (US State Department Human Rights Report, Freedom House, InSight Crime, reports of the National Mechanism for the Prevention of Torture). At the forefront stands the largest and most notorious facility, the Tacumbú prison in Asunción, which for a long time held a multiple of its capacity. Nationwide, a structural failing is established by occupancy rates well above the intended level and a share of around two-thirds of pre-trial detainees; reports describe sleeping places on the floor, deficient hygiene and medical care, violence among detainees, and the control of detention areas by criminal groups.
The dangerousness of these conditions has escalated repeatedly: in December 2023, eleven prisoners and one police officer were killed during a state operation to retake Tacumbú; during prison riots hostages were taken and inmates killed, and in individual cases prisoners were beheaded. In May 2026, as part of "Operation Umbral 3.0," the government transferred more than 450 inmates from Tacumbú to the Martín Mendoza facility in Emboscada and formally downgraded Tacumbú to a "Detention Center" — a restructuring that nevertheless does not eliminate the structural overcrowding and violence finding.
It follows from German case law that, on extradition to Paraguay, the review standard 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 the standard even outside the European Arrest Warrant) regularly weighs decisively against admissibility. A mere diplomatic assurance ("humane accommodation") does not suffice; what is required is a concrete, facility-specific and verifiable assurance naming the facility, with monitoring by the German Embassy in Asunción. In view of the documented situation and the simultaneous control of individual detention areas by criminal groups, a reliable, monitorable assurance is in practice difficult to obtain. The fact that the bilateral treaty of 1909 — unlike modern extradition treaties — contains no express human-rights and assurance clauses does not relieve the Higher Regional Court of its independent review by the standard of Article 3 ECHR; the Convention and the Basic Law take precedence over the treaty-based duty to extradite.
Consular assistance is provided through the German Embassy in Asunción on the basis of the Vienna Convention on Consular Relations of 24 April 1963 (VCCR). In the case of German-Paraguayan dual nationals, particular attention must be paid to effective consular access; the right to notification and visits under Article 36 VCCR must be consistently enforced in both the extradition proceedings and the subsequent enforcement proceedings.
Lines of defense
The defense in Paraguay extradition proceedings is regularly promising where it is structured by a lawyer at an early stage. Review grid:
- 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, Freedom House and the anti-torture mechanism on Tacumbú and on nationwide overcrowding; a concrete, facility-specific assurance with monitoring by the German Embassy in Asunción as the minimum requirement — and a bar where it cannot be monitored.
- Article 16(2) of the Basic Law in conjunction with Section 80 IRG (extradition of Germans): Excluded where there is German nationality — of particular practical significance in view of the large German-descent and dual-national community in Paraguay. It continues to bar extradition even for German-Paraguayan dual nationals.
- Section 73 sentence 1 IRG in conjunction with Article 6 ECHR (fair trial / judicial corruption): Where there is documented susceptibility to corruption and political influence over the judiciary, challenge the procedural fairness, the presumption of innocence and the body of evidence underlying the request.
- Section 3 IRG (dual criminality): Careful mirror-image review of the Paraguayan allegations; a maximum penalty of more than one year, or at least four months of sentence remaining for enforcement requests, is required.
- Reasonable suspicion and the body of evidence: For requests arising from the organized-crime environment of the tri-border area, review the sustainability of the grounds for suspicion — in particular where the incriminating evidence rests on statements from an environment that is corruption-prone or pervaded by criminal groups.
- Section 6 IRG (political offense / threatened persecution): To be examined in politically or economically connoted proceedings; it also covers an ostensibly "criminal" request behind which lies an ulterior purpose.
- Rule of specialty: Secure the binding of the extradition to the offenses granted; ensure a concrete enumeration in the granting decision, with supplementary requests only upon renewed consent (Section 11 IRG or the treaty-based specialty rule).
- Section 9 IRG (double jeopardy / ne bis in idem): Where there are parallel investigations in Germany or third countries, review the blocking effect.
- Interpol/CCF: Challenge a politically or economically motivated Red Notice or diffusion under Article 3 of the Interpol Constitution; file an early CCF deletion application and a protective brief with the BKA and the Federal Office of Justice.
- Constitutional complaint with an urgent application (Section 32 BVerfGG): The standard remedy after the OLG has declared the extradition admissible, 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); prospects are not slight where the detention-conditions challenge has been carefully prepared.
Legal representation in Paraguayan 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 alert, an SIS alert or a European Arrest Warrant.
As a Certified Specialist in Criminal Law with a focus on extradition law, I advise and represent affected persons nationwide before the competent Higher Regional Courts and in constitutional complaint proceedings before the Federal Constitutional Court.
