Overview
The Republic of Korea (대한민국, Daehanminguk — South Korea) has, since 29 Dec 2011, been a party to the European Convention on Extradition (ECE) — having acceded as a non-European state under Article 30(4) ECE. It has ratified the 1st and 2nd Additional Protocols; the 3rd and 4th Additional Protocols were not ratified. South Korea is not an EU member; the European Arrest Warrant does not apply.
Extradition traffic between Germany and South Korea is small in volume but unproblematic in quality. South Korea is a stable rule-of-law democracy with an independent constitutional judiciary (Constitutional Court of the Republic of Korea, 헌법재판소) and is regarded as one of the most reliable acceding states outside Europe. The focus is on economic and property crime (e.g. cybercrime, the crypto complex), money laundering and drug offenses.
Since the transition from military dictatorship in 1987, the South Korean judiciary has developed into one of the most democratically consolidated in Asia. Current political upheavals (President Yoon Suk-yeol's attempt to impose martial law on 3 Dec 2024, the impeachment proceedings) do not affect the enforcement of sentences or extradition proceedings in substance — the institutional stability has been preserved.
Legal basis
Extradition to South Korea is governed by the European Convention on Extradition of 13 Dec 1957 (ECE, BGBl. 1964 II p. 1369) in conjunction with the 1st Additional Protocol (15 Oct 1975) and the 2nd Additional Protocol (17 Mar 1978). The European Convention on Mutual Assistance in Criminal Matters of 20 Apr 1959 (ECMACM) applies in addition.
Domestically, the IRG applies on the German side (Sections 1 ff. IRG); for German nationals, Article 16(2) of the Basic Law in conjunction with Section 80 IRG operates as a bar. On the Korean side, the Extradition Act (범죄인 인도법, Act on Extradition, Act No. 4015 of 8 Aug 1988 as amended by subsequent revisions) and the Criminal Procedure Act (형사소송법, Criminal Procedure Act) apply.
The central authority for international mutual legal assistance on the Korean side is the Ministry of Justice (법무부, Ministry of Justice); for operational criminal prosecution, the Supreme Prosecutors' Office (대검찰청). On the German side, the Higher Regional Courts are competent in the admissibility proceedings; the granting decision is made by the General Public Prosecutor's Offices, and in matters of principle by the BfJ.
On the Korean side, the Seoul High Court (서울고등법원) decides exclusively on the admissibility of the extradition — as the central, sole extradition instance under Korean law (Article 3 of the Extradition Act). The granting decision is made by the Minister of Justice.
Country-specific issues in South Korea
No extradition of its own nationals: Under Article 9 no. 1 of the Korean Extradition Act, South Korea does not, as a rule, extradite its own citizens. The provision corresponds to the German bar under Article 16(2) of the Basic Law / Section 80 IRG. For Korean dual nationals an individual assessment is carried out — South Korea accepts dual nationality only on a limited basis (for men subject to military service, generally up to the age of 22 under special rules).
Death penalty — a de facto moratorium since 1997: South Korea has not formally abolished the death penalty; under Korean criminal law (형법) it is still provided for in 20+ offenses. In practice, however, a complete moratorium on executions has been in place since December 1997 — the last executions took place on 30 Dec 1997 (23 persons). South Korea has therefore been listed by Amnesty International as "abolitionist in practice" since 2007. Where charges carry a potential threat of the death penalty, obtaining a reservation-based assurance under Article 11 ECE is nonetheless standard practice.
Constitutional Court case law on the death penalty: The Korean Constitutional Court narrowly upheld the constitutionality of the death penalty in 1996 (decision 95Hun-Ba1) and 2010 (2008Hun-Ka23) (in each case 5:4 in favor of constitutionality). A third decision is expected; a full abolition is pending in the National Assembly's legislative process (a bill for a "Special Act on the Abolition of the Death Penalty" has been introduced several times, most recently in 2021).
Current political upheavals (the Yoon impeachment complex, December 2024 onward): The attempt by then-President Yoon Suk-yeol to impose martial law on 3 Dec 2024 led to the impeachment proceedings and the Constitutional Court decision. The institutional extradition structures remained unaffected by this; extradition traffic continues to run smoothly.
Military service and male dual nationals: South Korea has general conscription for men aged 18–28 (18–24 months of service). For German-Korean dual nationals, military-service constellations may arise that must be reviewed in the extradition proceedings as a Section 7 IRG question (military offenses).
Detention conditions and the human-rights review
The South Korean detention system is administered by the Korea Correctional Service (대한민국 교정본부) within the Ministry of Justice. It comprises around 53 facilities of varying security levels; central facilities are the Seoul Detention Center (서울구치소, Uiwang, the main remand facility for the greater Seoul area), the Seoul Nambu Correctional Institution, the Daegu Correctional Institution and the Cheongju Women's Correctional Institution.
The material detention conditions generally meet Western standards. Structural overcrowding in individual remand complexes (the Seoul Detention Center, averaging around 120 % occupancy) has been criticized repeatedly by the Korean National Human Rights Commission (NHRCK, 국가인권위원회); in decision 2013Hun-Ma142 of 28 Dec 2016 the Constitutional Court ruled on cell-space and defined minimum standards.
Reports of mistreatment are rare and not systematically documented. The CPT equivalent is the NHRCK, which has operated independently since 2001; its annual reports are usable as evidence.
In German extradition practice, Aranyosi arguments are rarely decisive in relation to South Korea. The defense therefore regularly concentrates on other points (dual criminality, double jeopardy (ne bis in idem), the rule of specialty, the death-penalty reservation in relevant offenses).
Lines of defense
The defense in South Korea extradition cases is oriented around the following points:
- Article 16(2) of the Basic Law in conjunction with Section 80 IRG (extradition of Germans): excluded for German nationals; for German-Korean dual nationals it continues to operate as a bar.
- Article 11 ECE (death penalty): where charges carry a potential threat of the death penalty, obtain a reservation-based assurance — even though a de facto moratorium has been in place since 1997.
- Dual criminality (Article 2 ECE): a minimum sentence threshold of 1 year on both sides; for special Korean offenses (e.g. the National Security Law, special electoral-law offenses), a careful subsumption review.
- Article 4 ECE / Section 7 IRG (military offenses): relevant for male dual nationals with military-service constellations.
- Political offenses (Article 3 ECE in conjunction with Section 6(1) IRG): for charges under the Korean National Security Law (국가보안법), a careful delimitation review — historically controversial during the democratization era, today applied more restrictively.
- Section 73 sentence 1 IRG in conjunction with Article 3 ECHR — detention conditions: generally unproblematic; in the event of overcrowding at the Seoul Detention Center, draw on NHRCK reports.
- Rule of specialty (Article 14 ECE): limitation to the offenses granted.
- Double jeopardy / ne bis in idem (Article 9 ECE): review the barring effect of parallel proceedings.
- Statute of limitations (Article 10 ECE): limitation periods for prosecution and for enforcement under both legal systems — Korean criminal law has significantly shorter limitation periods than German law (e.g. 25 years for murder following the 2007/2015 reform).
- Provisional extradition detention (Section 16 IRG, Article 16 ECE): can be ordered already on the basis of a Korean Interpol alert.
- Constitutional complaint with an urgent application (Section 32 BVerfGG): for constellations with fundamental-rights relevance — rarely central given South Korea's rule-of-law stability.
Legal representation in South Korean 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.
