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

Act quickly to identify the document and route: a foreign warrant or INTERPOL Red Notice does not, by itself, tell you which Slovenian procedure is under way. The deadlines below run from specific events such as service, arrest or consent, not simply from the date printed on a foreign document. This guide explains the main stages; a live case requires review of the actual order and applicable treaty.

Which procedure applies in Slovenia?

Chapter XXXI of Slovenia’s Criminal Procedure Act (Zakon o kazenskem postopku, ZKP), Articles 521–536, including Article 533a, governs traditional extradition unless a treaty or special instrument provides otherwise. The EAW is governed by the Cooperation in Criminal Matters with the Member States of the European Union Act (ZSKZDČEU-1). That Act also applies, with the necessary adaptations, to the separate surrender arrangements with Norway, Iceland and the United Kingdom. Those cases should not automatically be treated as ordinary third-country extradition.

The Council of Europe Treaty Office records Slovenia’s declaration on Article 14(3) of the Convention, as replaced by the Fourth Additional Protocol: Slovenia applies that provision in relation to other states that made the same declaration. The Treaty Office also records that the EAW framework replaces the Convention and earlier protocols to the extent that EU surrender law applies between the states concerned. Do not assume a treaty provision applies merely because Slovenia is a party to the Convention.

Which Slovenian court and authority handles the case?

For traditional extradition, the request normally travels through diplomatic channels and the relevant ministries to the investigating judge (preiskovalni sodnik) of the district court for the area where the person lives or is found: ZKP Article 524(1). The judge verifies identity, informs the person of the request and supporting material, hears the person and may order further inquiries. A panel of that district court decides whether the legal conditions for extradition are met.

After any additional inquiries, Article 526(2) requires the investigating judge to send any newly obtained evidence, together with the judge’s opinion, to the requested person, their lawyer (if any) and the prosecutor. The time allowed for comments must be at least eight days before the file is sent to the district-court panel.

If the panel finds the conditions met, the person may appeal to the higher court (višje sodišče). Unless a special rule applies, the general ZKP deadline for an appeal against a court order is 15 days from service under Article 400(2). Read the remedy notice on the actual order and obtain proof of when it was served. If the district court refuses extradition because the statutory conditions are absent, Article 527 provides for the refusal order to be sent automatically to the second-instance court for review; this is different from an appeal against a positive finding.

After a positive judicial finding becomes final, the file goes to the Minister of Justice. Under Articles 529–530 ZKP, the minister separately decides whether to permit extradition, refuse it or postpone it where a Slovenian criminal case or sentence makes postponement necessary. A judicial finding that the conditions are met is not itself the minister’s final authorisation. The Ministry of Justice is Slovenia’s central authority for international judicial cooperation, but it does not replace the court’s assessment.

What happens at each stage?

What must the foreign extradition request establish?

Under Articles 522–523 ZKP, the default route requires a foreign request submitted through diplomatic channels, unless the applicable treaty provides another method. The file must include material identifying the person and their nationality, an indictment, judgment, detention order or equivalent document, a description and legal classification of the conduct, supporting information for the suspicion or conviction, and the relevant foreign criminal-law text. Foreign-language requests and attachments must include a certified Slovenian translation under Article 523(4), subject to the narrow provisional-arrest rule explained below.

This is a route-and-document checklist, not an exhaustive analysis of refusal grounds. The evidence and legal arguments for refusal, including risk on return, belong on the separate Slovenia extradition refusal and appeal guide. A Red Notice may trigger urgent attention, but it is not itself a Slovenian extradition decision and does not replace the applicable legal process.

How long can provisional and extradition detention last?

Detention is not automatic merely because a request or alert exists. Under Article 524(3) ZKP, ordinary extradition detention requires a lawful basis and relevant detention grounds, including the statutory risk of absconding. Ask for the actual order, the risk it identifies, and whether a less restrictive measure can secure the person’s presence.

Article 525 ZKP allows urgent provisional arrest before the formal request arrives where there is a danger that the person will flee or hide. The foreign authority’s urgent request must identify the person and offence, identify the foreign detention decision, and state that a formal extradition request will follow. Police must bring the person before the competent investigating judge without delay. The judge sets the formal-request deadline; it cannot exceed three months from arrest. On the requesting state’s application, the court panel may extend it in a justified case by no more than two additional months. If the request misses the deadline or the detention grounds cease, release is required.

After the formal request arrives, Article 524(5) sets a different rule: detention may continue until surrender or the Minister of Justice’s refusal decision without separate extension orders, but the combined period before and after receipt of the request must not exceed 30 months. Article 524(6) requires earlier release if detention reaches the foreign sentence imposed or the maximum penalty prescribed for the offence in the requesting state. Thirty months is a ceiling, not a target duration or permission to disregard proportionality.

In XI Ips 15827/2016-79 (Supreme Court, 2 June 2016), the Court distinguished ordinary extradition detention, which generally requires a formally complete request and a statutory detention ground, from the narrow urgent provisional-arrest exception. In XI Ips 10257/2026 (22 July 2026), it held that a translated dispatch from a Slovenian authority summarising the foreign request may support provisional detention; the missing Slovenian translation of an attached Red Notice is not necessarily fatal at that preliminary stage. That ruling does not waive the full-request documentation and translation requirements.

What are the EAW deadlines and detention limits?

The EAW has its own timetable. If the person consents, the investigating judge must decide without delay and no later than 48 hours; the person and defence counsel may appeal that decision to the district-court panel within 24 hours from service, and the panel must decide within 48 hours (ZSKZDČEU-1 Article 22). If the person does not consent, the district-court panel decides whether to surrender. The person, defence counsel or prosecutor may appeal within 48 hours from service; the higher court must decide within three days (Article 23(7)). Keep the service record: the consent route uses a 24-hour appeal period, while the no-consent appeal period is 48 hours.

Under Article 26, a final surrender decision is due within 10 days after consent, or within 60 days after the requested person’s arrest or first hearing if there is no consent. If the court cannot decide in time, it must notify the issuing judicial authority and explain the delay; the period may then be extended by another 30 days. Exceptional circumstances require further notification through the statutory mechanism, including Eurojust. These are decision deadlines, not guaranteed physical handover dates.

EAW detention is governed by Article 24, not the traditional 30-month ceiling. The initial detention ordered by the investigating judge may last up to one month; the district-court panel may extend it, but total detention under that provision may not exceed nine months. Each extension may be for two months. An appeal against an extension order must be filed within three days from service, and the higher court must decide within three days (Article 24(8)). Calculate the deadline from the actual order, not from a general estimate of the case timetable.

The Supreme Court’s decision I Ips 31315/2026 (27 August 2026) confirms that the extraordinary request for protection of legality (zahteva za varstvo zakonitosti) is not available against a final EAW surrender order: Article 23 provides a complete remedies system for surrender without consent. Do not assume that an additional ordinary or extraordinary appeal will suspend transfer.

What if the requested person is a Slovenian citizen?

Article 47 of the Slovenian Constitution restricts extradition or surrender of Slovenian citizens unless the obligation arises under a treaty transferring part of Slovenia’s sovereign powers to an international organisation. That exception is why an EAW must be distinguished from traditional extradition to a third country. Under Article 522 ZKP, nationality is a central condition in the traditional route. If extradition is refused because the person is Slovenian, Article 527(4) provides for the documents to be sent to the competent prosecutor’s office for consideration of possible domestic prosecution. It does not guarantee that no prosecution will follow.

Dual nationality, residence, refugee status and the requesting state may affect which provisions apply. A family should give counsel reliable nationality documents early; an oral assertion or expired passport may not be enough to resolve the issue.

Does consent change the procedure or the speciality rule?

For traditional extradition, Article 529.a ZKP provides a simplified route when the person, after being advised by the investigating judge, voluntarily consents. The judge must explain the speciality principle and the consequences of waiving it. A waiver of speciality is voluntary and irrevocable. The decision is not a formality: it can affect whether the requesting state may prosecute the person for other earlier offences after transfer. A challenge to the investigating judge’s consent-based order must be filed within 24 hours from service; the district-court panel must decide within 48 hours.

Consent to extradition is not the same as waiving a hearing or waiving speciality. Speciality generally limits prosecution or punishment after transfer to the offence or offences for which extradition was granted, subject to the governing treaty and lawful exceptions. The person should understand the exact declaration, offences listed and consequences before signing. EAW consent and speciality are governed by the EAW-specific rules, not automatically by Article 529.a.

What happens after the court and minister decide?

Under Article 522(1)(14) ZKP, the judicial conditions for traditional extradition include that there be no likelihood of torture or inhuman or degrading treatment in the requesting state. Article 530(3) separately requires the Minister of Justice to refuse extradition if the person has been granted international protection or the alleged offence is political or military. Detailed refusal grounds and evidence belong on the separate Slovenia extradition refusal guide.

The Minister’s decision is distinct from the criminal court’s finding. Under ZKP Article 530a, it may be challenged before the Administrative Court within 15 days of service; the court must decide within 60 days, or within 30 days if the person is detained under Article 524. This is a separate administrative action, not a further criminal appeal. In X DoR 29/2026-3 (22 April 2026), the Supreme Court permitted a revision on whether the Minister is bound by a final judicial finding under Article 522(1)(14) when no new facts or evidence have emerged; that order allowed the question to be reviewed but did not decide it. Filing does not automatically suspend transfer.

Under Article 531 ZKP, a traditional extradition authorisation ordinarily records speciality conditions, including limits on prosecution for other earlier offences and on onward surrender to a third state, subject to statutory exceptions. Those protections may cease in circumstances set out in the statute, including if the person waives them or, after release, remains in the requesting state for 45 days despite being able to leave and having been warned of the consequences. Ask for the final written decision and handover arrangements; a hearing date alone does not establish when transfer will occur.

What should the person or family do first?

• Keep copies of every police record, court order, EAW, urgent arrest request, formal extradition request and ministerial decision.
• Record the exact date and time of arrest and service of each order; keep envelopes, electronic notices and proof of service.
• Ask counsel to identify the route before calculating deadlines: traditional extradition, EAW, or a separate Norway/Iceland/UK arrangement.
• Provide nationality documents, residence details, the requesting state, alleged conduct and dates, any judgment, and information about parallel Slovenian proceedings.
• Preserve evidence relevant to identity, limitation, prior proceedings, detention conditions or risk on transfer. Do not alter or destroy documents.
• Ask for an interpreter and make sure consent, waiver choices and objections are accurately recorded.
• If detained, obtain the actual order and ask counsel to assess its legal basis, necessity, review route and possible alternative measures.

A hypothetical example: an urgent request from outside the EU

Suppose a non-EU state asks Slovenia to extradite a foreign national living in Maribor and sends an urgent provisional-arrest request before its full file arrives. The alert alone does not decide whether extradition is lawful. Counsel should check the person’s identity, the detention order and grounds, and the judge’s deadline for the formal request. If the full request arrives, counsel should then examine the treaty relationship, translations, dual criminality, sentence thresholds, limitation, prior proceedings and statutory safeguards. The district court’s finding and the Minister of Justice’s decision are separate stages. This example is hypothetical; the outcome depends on the actual documents, requesting state and applicable treaty.

What can an extradition lawyer do?

At the start, counsel identifies the legal route, obtains the Slovenian orders and request documents, secures interpretation where needed, and protects the person’s ability to understand and answer the case. During judicial review, counsel tests identity, document completeness, statutory conditions and the legal basis for detention, and records objections supported by evidence.

After a positive traditional-extradition finding, counsel calculates the 15-day appeal period from service, unless a special rule applies, and addresses the separate ministerial stage. In an EAW case, counsel distinguishes the 24-hour appeal in the consent route, the 48-hour appeal without consent, and the three-day appeal against an EAW detention-extension order. Counsel should also explain speciality, conditions in the final decision and the practical handover process. No lawyer can promise a particular outcome.
