How to Stop Extradition from Germany: Grounds for Refusal, Appeals and Deadlines

First establish whether the request comes from another EU Member State under a European arrest warrant (EAW) or is an extradition request from a non-EU country. These are different legal tracks with different refusal grounds. The broader sequence of arrest, judicial examination and authorisation is explained in the guide to extradition from Germany; this page concentrates on how to resist surrender lawfully.

Which German decision can actually be challenged?

Under §§ 13 and 14 IRG, the OLG for the district where the person was arrested for extradition (or, without arrest, first located) decides judicial admissibility. The Staatsanwaltschaft bei dem Oberlandesgericht, commonly operating as the Generalstaatsanwaltschaft, prepares the case and implements an authorised surrender. For a non-EU request, the authorising authority also has an executive role under §§ 12 and 74 IRG. An admissibility decision is not itself permission for officials to hand a person over: counsel must identify precisely which decision is pending and who can prevent an imminent transfer.

The court is not a general appeals court reviewing the criminal prosecution abroad. In an EAW case it will generally not retry the underlying evidence of guilt. The OLG Köln decision of 21 January 2026 (3 OAus 144/25) confirms that a factual-suspicion review is ordinarily unavailable and illustrates the importance of testing German legal barriers instead. Its ruling binds that particular proceeding, not every OLG as a nationwide precedent; the EU-law and constitutional-law principles discussed below have wider authority.

Which refusal grounds work against which kind of request?

The following grounds are not interchangeable. An obstacle to Zulässigkeit (judicial admissibility) is different from a Bewilligungshindernis (reason to withhold authorisation). Some bars are absolute on proved facts; others require assessment of evidence or an express exercise of discretion.

A qualification to the life-sentence row matters: in its 21 January 2026 decision, OLG Köln held that for an EAW seeking prosecution it need not resolve the § 83(1) no. 4 life-sentence-review question when authorisation is expressly conditional on the requested person’s option to return to Germany for enforcement of a resulting custodial sentence. This case-specific approach does not abolish the statutory safeguard in other cases. Separately, the wording of § 8 IRG permits an assurance that the death penalty will either not be imposed or, if imposed, not be carried out; the individual reliability of that assurance still matters.

Treaty rules may modify the analysis of non-EU requests. Germany is party to the 1957 European Convention on Extradition (ETS 024), whose country-specific reservations and declarations must be checked against the requesting state's status; Germany's treaty declaration also records the priority of the EAW regime within the EU. The United Kingdom and Switzerland are not EU Member States, and neither request is an ordinary EAW between EU members. A competent lawyer checks the actual treaty and instrument, rather than applying § 83 IRG indiscriminately.

How do you challenge an EAW without treating the German court as a trial court?

Start with the warrant and its underlying judicial order, not solely an INTERPOL notice. Under § 83a IRG an EAW must identify the person, issuing authority, executable judicial basis, conduct including time and place, and penalty. An omission may justify a request for further particulars, but not every drafting problem defeats surrender permanently: § 30 IRG allows the OLG to ask the requesting state for supplementary material.

For a judgment given in the person's absence, ask exactly what the person knew, whether defence counsel actually represented them, whether notice was served and whether an effective retrial is guaranteed. Section 83(2)–(4) contains exceptions to the initial inadmissibility rule. The Federal Constitutional Court in 2 BvR 2735/14 (15 December 2015) set aside an OLG Düsseldorf order because the court had not adequately investigated whether an effective review would be available after surrender to Italy. It did not establish a blanket prohibition on executing warrants based on in-absentia judgments.

For alleged prison dangers, gather independently sourced prison inspections, credible reports, medical vulnerabilities and the particular detention facilities likely to be used. The CJEU judgment in Aranyosi and Căldăraru (C-404/15 and C-659/15 PPU) requires a two-stage risk inquiry; later CJEU decisions including Dorobantu (C-128/18) elaborate the assessment. In 2 BvR 1845/18 and 2 BvR 2100/18 (1 December 2020), the Federal Constitutional Court quashed German admissibility decisions that had failed properly to examine Romanian prison conditions. The practical demand is for concrete additional information or reliable assurances, not for a court to accept a vague warning untested.

The Federal Constitutional Court strengthened this evidential distinction on 5 August 2026 in 2 BvR 364/26: it set aside an OLG München admissibility ruling concerning Romanian prison conditions. Where the OLG itself accepted continuing systemic shortcomings, it had not sufficiently tested an almost two-year-old general assurance that named neither the individual nor a destination prison. This does not make all general assurances invalid: counsel must demonstrate why the assurances and the expected place of detention require a more specific inquiry in this case.

A recent limit cuts in the other direction: in Rugu and Aucroix (joined C-722/23 and C-91/24, 4 June 2026), the CJEU held that an EAW refused for a real Article 4 risk cannot additionally be classified as a residence-based Article 4(6) refusal merely to execute the sentence at home. Instead, the executing state must seek transmission of the judgment under the separate sentence-enforcement framework. This is why a successful refusal of surrender does not necessarily cancel the foreign sentence. EU-law interpretations of the CJEU are binding on German OLGs when applying that law.

The June 2026 Rugu ruling applies to EAWs seeking enforcement of an existing custodial sentence, not to every prosecution EAW. The requested state must seek transmission under Framework Decision 2008/909, but the issuing state is not automatically obliged to forward the judgment, and the prisoner's consent rules and exceptions must be examined. This is not an enforceable personal right to have every foreign sentence served in Germany.

Can a German citizen or resident insist on serving a sentence in Germany?

Citizenship, habitual residence and a request for prosecution rather than sentence enforcement are three different questions. Article 16(2) of the Basic Law protects Germans against extradition abroad but expressly permits statutory exceptions for EU Member States and international courts if rule-of-law principles are respected. Under § 80(1)–(2) IRG, a German facing an EU prosecution EAW needs the prescribed return-to-Germany arrangement and the appropriate factual connection and balancing; under § 80(3), surrender to enforce a sentence requires consent given after instruction in a judicial record.

A non-German habitually resident in Germany may argue the separate discretionary grounds in § 83b(2) IRG. A lease alone is not decisive: provide records of the person's actual centre of life and of any sentence that could be enforced domestically. Under § 79(2) IRG the OLG reviews the authorising authority's reasoned preliminary choice not to invoke § 83b; the court does not automatically replace that discretion with a preferred outcome. A 2026 OLG Köln case considered a return-for-sentence condition, illustrating why the requested safeguard must match the exact statutory barrier.

There is a separate EU-citizenship safeguard when a third country requests extradition for criminal prosecution of a citizen of another EU Member State from Germany. In Generalstaatsanwaltschaft Berlin (C-398/19, 17 December 2020), the CJEU required consultation with the Member State of nationality, provision of the relevant legal and factual information received with the extradition request and reasonable time for a possible EAW. Germany is not obliged simply to refuse the third-country request or prosecute the case itself. Counsel should immediately document all nationalities and ask whether the notification and fundamental-rights assessment occurred.

What is the correct route if the OLG has already said extradition is permissible?

1. Before an OLG ruling: supply admissibility objections, witness or documentary exhibits and a request for additional information under §§ 29–30 IRG. Separately ask the OLG under § 25 to suspend execution of the extradition detention warrant if less restrictive safeguards suffice.
2. After an OLG ruling: § 13(1) IRG states its decisions are final as to ordinary appeals. Section 33(1) obliges the OLG to decide again where later-arising circumstances could change admissibility; § 33(2) allows reconsideration when qualifying circumstances become known later. Identify precisely what changed or was discovered, attach proof, and request postponement under § 33(4) expressly.
3. Legal question of wider significance: § 42 IRG allows or requires a referral to the Bundesgerichtshof (Federal Court of Justice) by the OLG in the specified circumstances. It is not an appeal the requested person can file directly with the BGH, and no independent BGH deadline should be invented.
4. Constitutional rights: a Verfassungsbeschwerde lies to the Bundesverfassungsgericht (Federal Constitutional Court), subject to admissibility and exhaustion principles in § 90 BVerfGG. Under § 93(1), the usual time limit is one month, triggered according to how the complete decision is served, communicated or announced. Urgent protection requires a separate application for an interim order under § 32 BVerfGG; merely filing the complaint is not a stay.

A constitutional complaint is not a further factual hearing. Identify a constitutional or applicable EU fundamental-rights violation by the German decision, including a material failure to investigate a concrete risk; explain why ordinary options were exhausted and why intervention cannot wait. On 27 August 2026 the Federal Constitutional Court prohibited transfer to Poland for up to six months pending its constitutional-complaint ruling in 2 BvR 1430/26 while examining whether OLG Düsseldorf had adequately assessed prison-location assurances. That was an interim ruling, not a final finding that the transfer was unlawful. It expressly left the separate extradition-detention question unaffected.

What deadlines actually matter for a detained person?

How can surrender be paused while the risk is examined?

Apply to the competent OLG for a postponement under § 33(4) when seeking reconsideration, and seek a constitutional interim order under § 32 BVerfGG where an urgent constitutional case exists. A detention application under §§ 24–26 IRG addresses loss of liberty in Germany; it is not automatically a prohibition on transfer. Likewise a refusal or limitation at the authorisation stage is legally different from release on bail.

Germany is bound by the European Convention on Human Rights. In exceptional circumstances of imminent, irreparable harm, the European Court of Human Rights may indicate a Rule 39 interim measure to Germany. A request must identify the real harm, documents and intended handover date; filing alone creates no suspension. The ordinary Strasbourg application has distinct admissibility requirements, including exhaustion and a generally applicable four-month limit after the final domestic decision: Rule 39 is not a replacement for domestic emergency steps.

Germany has also accepted the individual-complaint procedure under the First Optional Protocol to the ICCPR, and the UN Human Rights Committee can consider requests for interim protection under its own rules. These are exceptional, separate avenues with admissibility conditions; they are not automatic stays and duplicate international proceedings can create obstacles. Counsel should select the forum after checking whether the same matter is already pending elsewhere.

Does an asylum claim or an INTERPOL deletion stop surrender?

Neither automatically does. Under § 6 of Germany's Asylgesetz, the normal binding effect of an asylum decision expressly does not extend to extradition proceedings. Refugee status, protection decisions or pending asylum material may be essential evidence of persecution or non-refoulement risk, but the extradition court must assess the relevant objection independently. Extradition and immigration removal have different decision-makers and remedies; starting an asylum case should never be presented as a reliable legal stay of an extradition order.

An INTERPOL Red Notice is not a German surrender judgment. An affected person may ask the Commission for the Control of INTERPOL's Files (CCF) to access, correct or delete INTERPOL-held information. Since 26 March 2026, applications must normally be sent through the CCF's dedicated online portal. Even a successful deletion does not itself quash a German extradition-detention order or a separate EAW: transmit the outcome to German counsel and seek the appropriate domestic ruling.

What evidence should counsel submit first?

• Every German order with date, proof of service and proposed handover date; the EAW or treaty request and any translations.
• Proof of identity, nationalities and actual residence; German family, employment or medical records where legally relevant.
• For a prior case: certified operative judgment, finality and sentence-enforcement status, with an analysis matching the same acts.
• For a default conviction: summons, evidence of knowledge, representation and foreign retrial provisions; have counsel in the requesting country confirm the real remedy.
• For political persecution, death penalty or detention danger: credible dated reports plus individual incidents, facility information and any proposed diplomatic assurances.

Hypothetical example: a Georgian national arrested near Frankfurt on an EAW from an EU state says that the intended prison would aggravate a documented serious illness. The defence should not argue merely that the foreign prosecution is unfair. It should provide medical records, reliable prison evidence, request concrete information from the issuing authority through the OLG, and assess urgent interim relief against the actual transfer date. If the same person instead faced an ordinary non-EU request, the statutory and treaty objections would need to be rebuilt rather than mechanically reusing the EAW grounds.

Which mistakes commonly defeat a potentially valid objection?

Do not assume an ordinary appeal exists against the OLG's decision, confuse the 60-day EAW target with an appeal deadline, or expect the German court to determine guilt abroad. Do not sign irrevocable consent to simplified extradition under § 41 before understanding the consequences, including a separate possible waiver of speciality. Do not claim that German citizenship always prevents EU surrender, or that asylum recognition binds the extradition judge. Finally, do not wait for a CCF, constitutional or Strasbourg response without securing an actual pause from a competent decision-maker.
