Extradition from Finland: How the Procedure Works and What an Extradition Lawyer Does

Which legal route applies to a request made in Finland?

Section 1 of the Extradition Act (456/1970; laki rikoksen johdosta tapahtuvasta luovuttamisesta) separates ordinary extradition from EU and Nordic procedures. A Red Notice or arrest alert may prompt police action, but is not itself a final Finnish extradition decision.

Finland ratified the European Convention on Extradition (ETS No. 24) on 12 May 1971; it entered into force for Finland on 10 August 1971. Finland’s declaration under Article 6 defines “nationals” for Convention purposes to include citizens of Finland, Denmark, Iceland, Norway and Sweden, as well as foreign nationals domiciled in those states. Finland’s Article 28 declarations provide for applying its EU surrender legislation in relations with EU Member States and exclude Convention extradition between Finland and the other Nordic states, where a uniform legal regime applies. For a request from a non-EU, non-Nordic state, verify that the Convention is in force between Finland and the requesting state and check any applicable protocols; these declarations do not replace identifying the actual legal basis.

Who handles ordinary extradition from outside the EU?

Under sections 14–15 of Act 456/1970, the Ministry of Justice decides and sends any request not immediately rejected to the NBI for urgent investigation. Requests normally arrive through diplomatic channels unless another arrangement applies. If the documents show no lawful basis for extradition, the Ministry must reject the request immediately; otherwise, it sends the file to the National Bureau of Investigation (Keskusrikospoliisi; NBI) for an urgent investigation. Police check identity and circumstances, record the person's position and return the file. The Ministry may seek additional information from the requesting state.

The Supreme Court of Finland (Korkein oikeus) is not an ordinary appeal court in this route. Under sections 16–17, a person who states during the investigation or in a written submission before the Ministry decides that legal grounds are absent triggers a Supreme Court opinion, unless the request is immediately rejected. The Ministry may also request an opinion on its own initiative. If the Court identifies a legal obstacle, extradition cannot be granted. Section 34 excludes an appeal against the Ministry's decision, so legal objections should be raised clearly before the decision.

Section 9 requires an enforceable judgment supported by adequate evidence or a remand warrant based on evidence of probable guilt, subject to the applicable treaty. Under section 4, ordinary extradition generally requires the act to carry a maximum of at least one year's imprisonment under Finnish law, or to be treated as an offence meeting that threshold if committed in Finland in corresponding circumstances; for sentence enforcement, the imposed custodial sentence must be at least four months. Sections 5–8 set key refusal limits. Separately, section 9(4) of Finland's Constitution prohibits extraditing or returning a foreign national where the person would face the death penalty, torture or other treatment violating human dignity. The EU Surrender Act has mandatory grounds (§5), discretionary grounds (§6) and special rules for convictions in absentia (§6a). Detailed refusal grounds and arguments belong on How to Stop Extradition from Finland. Section 12 also contains a speciality rule: a person generally may not be prosecuted or punished for another earlier offence without required consent, subject to exceptions and the applicable treaty. Transit is separate: under section 33, the Ministry may permit passage through Finland of a person extradited between foreign states, but a Finnish citizen may transit only within the statutory Nordic or EU exception.

What happens after an arrest or provisional-arrest request?

A person may be detained before the formal request arrives. Under section 31 of Act 456/1970, this may follow a foreign state's request or warrant for an extraditable offence. The Ministry of Justice must be notified promptly and sets the deadline for the formal request: normally 30 days from notification to the requesting state, or up to 45 days for special reasons. If the request does not arrive in time and no other lawful basis for custody exists, release is required. Check the notification date and applicable treaty immediately.

The district court for the municipality where the person is detained must be informed and urgently decide whether custody should continue. This is not necessarily Helsinki District Court: that court handles EAW surrender under section 11 of Act 1286/2003, while ordinary extradition custody is first reviewed locally. Under section 20 of Act 456/1970, the person may request reconsideration at any time, and the court must review it within two weeks. Section 22 permits a complaint to the Supreme Court without a fixed filing deadline in the stated circumstances.

Section 31a allows a travel ban instead of custody. No single maximum detention period applies after the formal ordinary-extradition request arrives, but continued custody remains reviewable and the defence may challenge unnecessary delay. If the Ministry approves extradition, section 21 requires it to set a handover period that normally does not exceed one month from notification of the decision and can never exceed two months.

How does an EU European Arrest Warrant proceed?

An EAW is a judicial surrender request, not a ministerial extradition request. Under section 11 of Act 1286/2003, Helsinki District Court (Helsingin käräjäoikeus) decides surrender and continued custody. Prosecutors in its judicial district generally handle the case, subject to exceptions. The National Bureau of Investigation (Keskusrikospoliisi; NBI) coordinates the request, serves it, explains its contents and records the person's position. Under section 15, the request must be in Finnish, Swedish or English or include a translation into one of those languages; the person is entitled to information and language assistance they understand. Under section 2, the ordinary dual-criminality route generally requires an offence punishable by a maximum of at least one year in the issuing state and an equivalent offence under Finnish law; for sentence enforcement, the imposed custodial sentence must be at least four months. Section 3 removes the dual-criminality check for its specified offence list when the issuing-state maximum is at least three years.

The 60-day final-decision period differs from the district court's 26-day limit; special cases may extend the framework to 90 days under the current Act (amendment 371/2025). In C-804/21 PPU, the Court of Justice held that a person must be released if post-decision surrender limits expire, although lawful anti-absconding measures may remain available. Force-majeure extensions require prescribed coordination. Calculate from the actual arrest and consent dates; appeal deadlines are covered on the remedies page.

What custody, language and legal-aid rights apply?

For an EAW, the prosecutor asks Helsinki District Court to continue custody; the court may do so if surrender would otherwise be endangered. Section 17 permits a travel ban instead. Under section 19, a custody-continuation complaint may be filed with the Supreme Court without a fixed deadline. Disputing the warrant does not itself require release; the court must decide on the facts.

Sections 20a and 21 require police/NBI to explain the right to inspect the request, consult counsel, request appointed counsel, receive interpretation or translation, be heard by the district court and decide whether to consent. Oral translation is allowed only if written translation is not needed for effective legal protection. The person must also be told about appointing counsel in the issuing state. Consent may be revoked until enforcement, after which the court reconsiders the matter and the time calculation changes. Consent to surrender, prosecution for other earlier offences and subsequent surrender are separate decisions.

Section 24 of the ordinary Extradition Act gives the person a right to counsel and provides for appointed defence counsel on request, paid from state funds at a reasonable rate. The EU and Nordic Acts have their own appointment rules. Ask promptly, and do not assume a Finnish lawyer also represents the person abroad; an EAW subject may appoint counsel in the issuing state too.

Can Finnish citizenship or residence change the route?

For ordinary third-country extradition, section 2 of Act 456/1970 bars extradition of Finnish citizens. The EAW Act permits surrender to another EU Member State, but section 8 can require return to Finland to serve a sentence for a citizen or person legally resident for at least five years, if the person asks and statutory conditions are met.

KKO 2025:69 confirms a further distinction in ordinary extradition: although Finland’s Article 6 declaration under the European Convention reserves a right to refuse extradition of certain foreign residents, that declaration does not extend section 2’s absolute statutory bar beyond Finnish citizens. In that case, the Supreme Court found a separate section 3 obstacle based on the alleged conduct in Finland and a material difference between the possible Albanian sentence and the Finnish sentencing range.

Since the 2025 amendment, section 6(1)(6) of the EU Surrender Act also provides a separate discretionary refusal ground for an EAW seeking enforcement of a custodial sentence: the person must be a Finnish citizen or have permanently resided or legally stayed in Finland for at least five years, must request to serve the sentence in Finland, and refusal must facilitate reintegration or be justified by special reasons. The court may consider the nature and conditions of the stay and family, language, cultural, social and economic ties; exceptionally significant ties may justify refusal even before five years. This is not automatic and is distinct from section 8’s return condition for surrender for prosecution.

For a non-Finnish EU citizen sought by a third country, Raugevicius (C-247/17) requires equal treatment with Finnish nationals in the relevant sentence-enforcement situation where the person is permanently resident and Finnish law allows the sentence to be served in Finland. KKO 2019:26 limits this approach on the residence issue: a Lithuanian citizen who was only visiting Finland was not a permanent resident, so EU citizenship alone did not prevent extradition under the Raugevicius line. Separately, the Supreme Court concluded that the request could not be granted because the verified risk of inhuman or degrading treatment in Turkey had not been dispelled. Do not read the residence holding as approval of the extradition. The rule is fact-specific, not blanket immunity for EU citizens or dual nationals.

The Nordic Act was amended with effect from 10 July 2025. It includes a discretionary route for some sentence-enforcement requests involving Finnish citizens or people who have legally resided or stayed in Finland for at least five years and ask to serve the sentence here. The court must assess reintegration or special reasons; residence alone does not automatically prevent surrender. Give counsel proof of nationality, lawful residence, family and social ties, and any request to serve the sentence in Finland.

The Nordic Act has its own shorter timetable. Under section 29, the district court must decide within three days after consent and, in any event, within 14 days after the person is apprehended or otherwise found in Finland, unless a special reason prevents this. Section 43 generally requires handover within five days after the surrender decision becomes final, with separate rules for exceptional circumstances and postponement. Do not substitute the EU Act’s 26-day first-instance timetable for a Nordic case.

What if Finland has a pending case, or several states want the same person?

A Finnish prosecution or sentence may delay extradition. Section 11 of Act 456/1970 can prevent immediate surrender, although it allows limited temporary handover for particularly serious proceedings. EU and Nordic laws also permit postponement or temporary surrender in defined situations. The court must identify the statutory basis and any return conditions; delay is not automatic.

In KKO 2025:68, the Supreme Court postponed an EAW surrender to Poland until serious Finnish criminal proceedings ended, because surrender would have impaired the defence. This fact-specific application of section 49 of Act 1286/2003 does not mean every pending case postpones surrender. If several states seek a person under ordinary extradition, section 25 assigns the choice to the Ministry of Justice; under EU and Nordic procedures, the court applies the relevant statute.

The CJEU’s judgment in CJ (C-492/22 PPU) also confirms that a postponement under Article 24(1) of the EAW Framework Decision must be decided by the executing judicial authority, not merely by police or an administrative body. If the applicable surrender deadlines expire without a valid judicial postponement or other lawful extension, the person must be released; lawful non-custodial measures to prevent absconding may remain available. Postponement is not automatic.

What should the person and family prepare now?

Send counsel available records promptly, even if the file is incomplete.

• Arrest record, Red Notice or alert, EAW or formal request, and supporting warrant or final judgment.
• Exact arrest date and time, provisional-arrest notification date, custody decisions, hearing notices and any surrender date.
• Passports and proof of citizenship, lawful residence, family ties, employment, language and community links.
• Any Finnish investigation, charge, trial, sentence or appeal affecting timing or enforcement.
• For an absentia conviction, keep the summons, judgment, proof of service and any retrial or review documents. The CJEU’s Khuzdar judgment (C-95/24, 21 May 2026) concerns the separate EU sentence-recognition rules and clarifies why the record of notice and waiver can matter.
• Medical records and any specific, reliable evidence about detention conditions or risks in the requesting state.
• A short chronology and urgent questions about the file-holder, next deadline, custody review and any recorded consent.

Hypothetical example: after an EAW arrest, counsel should obtain the warrant and exact arrest time and prepare for the Helsinki District Court hearing; if the decision is adverse, follow the appeal instructions and remedies guide immediately. For a provisional arrest on a non-EU request, establish when the requesting state was notified: the formal request is generally due within 30 days, or 45 for special reasons.

Which remedies come after the decision?

The route depends on the instrument: EAW surrender decisions can be taken to the Supreme Court subject to leave to appeal; an ordinary Ministry of Justice decision is not appealable under section 34, although a pre-decision objection may trigger a Supreme Court opinion; Nordic decisions have their own appeal route.
