Poland handles extradition through two separate tracks. Requests from EU member states move under the European Arrest Warrant, a judge-to-judge process that can finish in weeks. Requests from non-EU countries travel through diplomatic channels, go before a Polish court, and end with a decision by the Minister of Justice. Polish citizens get strong constitutional protection in both tracks, with an absolute bar on surrender outside the EU and only a narrow opening inside it.
Which System Applies to Your Case
The country making the request decides which rulebook Poland uses. An EU member state issues a European Arrest Warrant under the 2002 Framework Decision, and Polish courts handle it directly without any role for the executive branch. A non-EU country, including the United States, uses traditional extradition grounded in a treaty. For the U.S., that treaty was signed in 1996 and entered into force in 1999. For most of Europe outside the EU, the governing instrument is the 1957 European Convention on Extradition. Both tracks are built into the Polish Code of Criminal Procedure, which gives each its own chapter.
What Offenses Can Lead to Extradition
Traditional extradition requires dual criminality. The conduct has to be a crime in both Poland and the requesting country. It also has to be serious enough to meet a minimum sentence threshold. Under the 1957 European Convention, the offense must carry a maximum penalty of at least one year of imprisonment when the person is wanted for prosecution, or at least four months of sentence still to serve when the request is to enforce a conviction.1UK Foreign, Commonwealth & Development Office. European Convention on Extradition The U.S.-Poland treaty sets the threshold slightly higher, requiring a maximum penalty of “more than one year.”2U.S. Department of State. Extradition Treaty Between the United States of America and the Republic of Poland
The European Arrest Warrant works differently. For 32 listed categories of serious crime — including terrorism, human trafficking, organized crime, fraud, murder, and cybercrime — Poland does not check dual criminality at all. The only requirement is that the offense carries a maximum penalty of at least three years in the country that issued the warrant.3European Commission. European Arrest Warrant For offenses outside those 32 categories, Poland can still demand that the conduct be criminal under Polish law before agreeing to surrender.
How a Non-EU Extradition Request Moves Through Poland
A traditional request arrives through diplomatic channels and goes to the Polish Ministry of Justice. The Ministry checks the paperwork and sends it to the national prosecutor, who brings the case before the competent regional court. The court is where the legal argument happens. It examines dual criminality, the severity threshold, document completeness, and whether any ground for refusal applies. The person sought has the right to appear, present evidence, and challenge the request.
A court finding that extradition is legally admissible is not the final answer. The Minister of Justice makes the ultimate decision and can refuse surrender even after the court has approved it. That discretion exists so humanitarian or political factors outside the court’s narrower legal review can still block a transfer.
Provisional Arrest Before the Full Request Arrives
In urgent cases, a country can ask Poland to arrest someone before the complete extradition file is ready. Under the U.S.-Poland treaty, the request can come through diplomatic channels, directly between justice departments, or through INTERPOL. If Poland does not receive the full extradition request and supporting documents within 60 days, the person must be released. Release at that point does not block a later arrest if the paperwork eventually arrives.2U.S. Department of State. Extradition Treaty Between the United States of America and the Republic of Poland
How a European Arrest Warrant Moves Through Poland
The EAW is faster and runs entirely between judicial authorities, with no diplomatic step and no role for the Minister of Justice. Polish law gives the court 40 days from arrest to make an initial decision on surrender and 60 days to issue a final decision. An additional 30 days is possible in exceptional circumstances, and any delay must be reported to the issuing country.
Consent compresses the schedule sharply. If the arrested person agrees to surrender, the Framework Decision calls for a final decision within 10 days of that consent. Consent must be given before the executing judicial authority, and the person must have access to a lawyer first. Once given, consent generally cannot be withdrawn, although individual member states may allow revocation under their own rules.4EUR-Lex.

When Poland Will Refuse to Extradite
Several grounds for refusal apply to any request. Poland will not surrender someone for a political offense committed without violence, for conduct the person has already been tried for, or where there is a real risk of the death penalty, torture, or inhumane treatment. Article 55 of the Constitution forbids any extradition that would “violate rights and freedoms of persons and citizens.”5Sejm of the Republic of Poland. Constitution of the Republic of Poland Polish courts also have an independent obligation under Article 3 of the European Convention on Human Rights to assess whether surrender would expose the person to prohibited treatment, and diplomatic assurances from the requesting country must offer a practical guarantee, not just a theoretical one.
The European Court of Human Rights added structure to this review in Liu v. Poland in 2024. Where credible international reports document widespread ill-treatment in a requesting country’s prisons, Polish courts must give those reports significant weight and may relieve the person of the burden of showing an individualized risk.
Under the EAW specifically, three grounds for refusal are mandatory. Surrender is blocked if the offense is covered by an amnesty in Poland and Poland had jurisdiction to prosecute it, if the person has already been finally convicted or acquitted for the same acts in any EU member state and any sentence has been served or is being served, or if the person was under the Polish age of criminal responsibility when the offense occurred.
Several EAW grounds are optional, meaning the court may refuse but is not required to. These include an offense outside the 32 listed categories that fails dual criminality, a parallel Polish prosecution for the same conduct, expiration of the statute of limitations under Polish law, conduct committed partly or wholly on Polish territory, or a conviction in absentia without adequate notice. In absentia convictions can still result in surrender if the person knew about the trial, was represented by a lawyer, or will be informed of a right to retrial after arrival.4EUR-Lex. Council Framework Decision 2002/584/JHA on the European Arrest Warrant
Polish Citizens and the Constitutional Bar
Article 55 of the Polish Constitution starts from a flat prohibition on extraditing Polish citizens. For traditional requests from non-EU countries, that bar is absolute. Poland will not hand a Polish national to a non-EU state for prosecution or to serve a sentence.5Sejm of the Republic of Poland. Constitution of the Republic of Poland
When Poland joined the EU, Article 55 was amended to open a narrow door for the European Arrest Warrant. A Polish citizen may be surrendered to another EU member state, but only when the request rests on a ratified treaty or an implementing statute, the offense was committed outside Polish territory, and the conduct was criminal under Polish law both when it occurred and when the request was made. Even then, the court can condition surrender on the person being returned to Poland to serve any resulting sentence, so a Polish national convicted abroad after an EAW transfer may serve prison time in a Polish facility.
The Specialty Rule After Surrender
Someone surrendered under either system generally cannot be prosecuted in the receiving country for offenses other than those listed in the extradition request or warrant. This specialty rule stops a country from using an extradition for one charge as a route to prosecute someone for unrelated conduct.
Under the EAW, the protection has limits. It falls away if the person stays in the issuing country more than 45 days after release when they could have left, if the new offense carries no prison sentence, if the person consented to surrender and waived specialty at the same time, or if they expressly renounce the protection after arrival. The executing judicial authority can also give separate consent for additional charges.4EUR-Lex. Council Framework Decision 2002/584/JHA on the European Arrest Warrant
