Extradition Between Ukraine and the Czech Republic: Legal Framework, Procedures and Defence Options

When a Ukrainian national faces an extradition request from the Czech Republic—or vice versa—no bilateral treaty governs the process. This absence forces reliance on multilateral conventions, diplomatic channels and the requested state’s domestic law, which lengthens timelines considerably and adds procedural layers. Our team has defended clients in extradition proceedings across 19 jurisdictions, including Ukraine-EU cases where traditional treaty methods remain the only option.

Extradition is the formal surrender of a person by one state to another for criminal prosecution or sentence enforcement, conducted under treaty obligations, domestic law or reciprocity, subject to double criminality and human rights safeguards.

Double criminality is the requirement that conduct forming the basis of an extradition request must constitute a criminal offence in both the requesting and requested state, typically carrying a minimum penalty of one to two years’ imprisonment in each.

European Arrest Warrant (EAW) is a streamlined judicial surrender mechanism established by Council Framework Decision 2002/584/JHA, applicable exclusively between European Union member states. It abolishes traditional extradition barriers including the political offence exception and, in most cases, the own nationals exception.

No bilateral extradition treaty currently exists between Ukraine and the Czech Republic. UN treaty databases and official government records show that negotiations may have begun—both countries are listed as having “initiated” talks on extradition—but no finalized binding agreement has been concluded. The practical consequence: if you face an extradition request, your defence must work within a more fragmented legal framework with fewer procedural certainties and longer delays.

When no treaty binds the two states, the requesting country bears a heavier burden. Rather than filing through streamlined judicial channels, its prosecutors submit extensive documentation via diplomatic channels—the arrest warrant, statement of facts, criminal statutes, and evidence establishing probable cause. That submission alone can stretch two to four months. The UN Model Treaty on Extradition provides general principles (double criminality, minimum penalty thresholds) but these are not automatically binding unless both countries have adopted them into domestic law. The Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons, which both Ukraine and the Czech Republic joined, covers specific offences like attacks on diplomats. It does not, however, establish extradition procedures—enforcement still requires a separate treaty or reliance on domestic law.

What happens when no bilateral extradition agreement exists?

Three fallback mechanisms apply. First, states may invoke UN Model Treaty principles as a guideline, though these carry no legal force unless domestic law adopts them. Second, the requested state’s own extradition statute governs admissibility, timelines and refusal grounds; each jurisdiction sets its own evidentiary standards and human rights thresholds. Third, reciprocity allows the requested state to grant extradition on the condition that the requesting state would do the same in reverse—but this remains discretionary and unpredictable.

Delays are structural. Diplomatic negotiation replaces direct judicial cooperation. Ministries of justice, ministries of foreign affairs and national central bureaus must coordinate. After the requesting state assembles its documentation package and submits it through official channels, the requested state conducts judicial review. Courts examine identity verification, double criminality, specialty principle assurances (the promise that the person won’t be prosecuted for unrelated offences) and human rights protections. This stage typically takes three to twelve months, depending on case complexity and appeal availability.

The requesting state must meet a higher evidentiary bar. Without the mutual recognition principle that governs the European Arrest Warrant, the requested state’s courts scrutinise the factual and legal foundation of the allegations. Evidence must establish a prima facie case or probable cause under the requested state’s standard—not merely satisfy the requesting state’s threshold. Procedural defences once common in extradition law—the political offence exception, the fiscal offence exception, the own nationals exception—remain available and are frequently invoked. The EAW system has abolished or restricted these defences for intra-EU cases, but they persist in Ukraine-Czech proceedings.

The European Arrest Warrant does not apply. Ukraine is not an EU member state, and the EAW mechanism, established by Council Framework Decision 2002/584/JHA, operates exclusively between European Union members. The Czech Republic, an EU member since 2004, uses the EAW for intra-EU cases but must revert to conventional extradition when dealing with third countries, including Ukraine.

The speed difference is striking. Under the EAW, executing judicial authorities must decide on surrender within 60 days of arrest, extendable to 90 days only in exceptional circumstances. These deadlines are fixed by regulation and enforced by the Court of Justice of the European Union. Traditional extradition between Ukraine and the Czech Republic has no fixed maximum timeline; the process depends on diplomatic negotiations, domestic court schedules and appeals, often stretching well beyond two to three months. The EAW also eliminates the double criminality requirement entirely for 32 listed offence categories (those carrying a maximum penalty of at least three years), a shortcut unavailable in Ukraine-Czech cases where double criminality must be verified for every offence.

The EAW rests on a presumption of mutual trust: all EU member states are deemed to uphold equivalent standards of judicial independence, fair trial rights and detention conditions, so executing states surrender requested persons without verifying the requesting state’s criminal procedure or prison system. Ukraine falls outside this framework. Czech courts must independently assess whether Ukrainian criminal proceedings and detention conditions meet European Court of Human Rights standards before authorizing surrender—a time-consuming inquiry with no equivalent in EAW cases.

What is the difference between European Arrest Warrant and traditional extradition?

Speed comes from how the two systems communicate. EAW requests move directly between judicial authorities through the Schengen Information System (SIS II) or secure electronic networks—hours, not weeks. Traditional extradition requires diplomatic channels: the requesting state’s ministry submits to the requested state’s ministry, which forwards it to the competent court. Translation, formal acknowledgement and scheduling add weeks or months before substantive review even begins.

Double criminality verification differs fundamentally. For 32 offence categories under the EAW (if they carry at least a three-year maximum penalty in the issuing state), no double criminality check occurs at all. For other offences, the executing authority needs only to confirm that the alleged conduct—not its legal label—constitutes a crime under its own law. Traditional extradition demands strict double criminality: the conduct must constitute a criminal offence under the laws of both states, typically requiring a one to two year minimum penalty in each. This threshold excludes many economic, regulatory and fiscal offences entirely.

Refusal grounds are narrower under the EAW. The Framework Decision exhaustively lists mandatory and optional refusal grounds, preventing member states from inventing additional reasons. The political offence exception, once central to extradition law, is entirely absent. The own nationals exception survives in some member states (including the Czech Republic) only where domestic law permits execution of the sentence at home. Traditional extradition permits refusal on political motivation, fiscal character, military offences, nationality and humanitarian concerns, leaving the requested state broad discretion.

How long does the extradition process take?

Under the European Arrest Warrant, the law prescribes maximum timelines: the executing judicial authority must render a final decision within 60 days of arrest, extendable to 90 days only for complex legal or factual questions. Surrender typically follows within 10 days of the final decision. Total duration from arrest to surrender averages two to three months for straightforward cases.

Without a bilateral treaty between Ukraine and the Czech Republic, no statutory maximum exists. Provisional arrest via Interpol Red Notice can hold a person while the requesting state prepares its case—a process that takes weeks or months. Once the formal extradition request arrives, the requested state’s court must review identity, double criminality, specialty principle assurances and human rights concerns. This judicial phase alone typically consumes three to twelve months, depending on case complexity, availability of appellate review and court backlogs. If the person challenges the request or raises human rights objections, the timeline extends further. Expect the entire process—from provisional arrest to final surrender—to take anywhere from six months to two years or longer in contentious cases.

Without a bilateral treaty, extradition between Ukraine and the Czech Republic moves through multiple stages—each with its own timeline. First comes the ministry review: 30 to 60 days to check documents are complete, properly translated, and meet legal thresholds. Delays here are common; incomplete submissions simply restart the clock. Once cleared, the case reaches a court, which schedules a hearing, verifies identity, tests whether the conduct is criminal in both countries, and weighs defences on human rights or procedural grounds. This judicial phase stretches three to twelve months depending on evidence complexity and how many appeal levels get involved. If the person appeals, add another several months. Finally, after the court says yes, the executive side issues a surrender order and arranges logistics—another 30 to 90 days. Total time from arrest to handover: considerably longer than the European Arrest Warrant’s 90-day maximum, sometimes running eighteen months or more.
