A passport flagged at Warsaw Chopin or Kraków Balice. An officer stepping away from the desk. The minutes that follow are not random – they are the product of a file assembled in another country, processed through INTERPOL, and now sitting in a Polish system that will, within hours, trigger a statutory legal sequence. That sequence has rules, and those rules can be used.
Extradition defence in Poland turns on two parallel tracks: the domestic court procedure, which is governed by the extradition provisions of Polish criminal procedure law, and – where a Red Notice is involved – the separate but interacting review available before the Commission for the Control of INTERPOL's Files (CCF). A Red Notice is not an arrest warrant and not a judicial decision; it is a request to locate and provisionally detain a person with a view to extradition. Poland is not obliged to surrender, and its courts examine the request on its merits.
As of mid-2025, we are seeing a sustained rise in extradition requests directed at individuals detained in Poland, particularly from non-EU states. This page sets out what the procedure actually involves, which grounds carry weight, and what determines whether a defence succeeds or fails.
What does extradition procedure in Poland actually look like?
The Polish court process moves faster than most clients expect, and the first hearing is where the procedural shape of the case is fixed. Under the extradition provisions of Polish criminal procedure law, once a person is detained – whether on foot of a Red Notice, a diffusion or a formal extradition request routed through diplomatic channels – the court must examine the basis of detention promptly. This is not a full merits hearing. It is the moment at which provisional arrest is confirmed or lifted, bail conditions are set or refused, and – critically – the first arguments are placed on the record.
In our extradition practice, we have seen repeatedly that a poorly argued first hearing creates a factual and procedural record that is difficult to correct later. Polish criminal courts are experienced at extradition matters and do not respond well to arguments raised for the first time at appeal. The quality of the initial submission – the challenge to dual criminality, the human-rights evidence, the characterisation of the underlying offence – determines the trajectory of the whole case.
After provisional arrest, the requesting state has a defined period under the applicable rules to transmit a formal extradition request. If that request is deficient or does not arrive in time, the detention basis weakens. Tracking that deadline is a practical task that requires allied counsel in Poland from day one, not week three.
Which grounds carry real weight in Polish extradition proceedings?
Dual criminality is the threshold question in every Polish extradition case involving a non-EU requesting state. Polish courts examine whether the conduct alleged by the requesting state would constitute a criminal offence under Polish law if committed on Polish territory. This is a technical analysis, not a political one, and it is often more productive than it looks.
Several patterns recur. First, offences framed broadly under the requesting state's law – particularly economic offences in CIS jurisdictions – frequently do not map cleanly onto Polish criminal categories. A charge of "misappropriation" or "abuse of authority" may dissolve under close examination into conduct that Polish law does not criminalise in the same way. Dual criminality must be established for each alleged act, not for the label attached to the charge.
Second, the political-character bar matters. Article 3 of INTERPOL's Constitution bars the processing of data linked to offences of a political, military, religious or racial character. Polish courts, in our experience, are willing to receive evidence that the underlying prosecution is politically motivated – but that evidence must be documentary and specific, not merely asserted. General country-conditions material is a starting point, not a conclusion.
Third, Article 2 of INTERPOL's Constitution requires INTERPOL's activity to respect human rights in the spirit of the Universal Declaration of Human Rights. In the extradition context, this interacts with Poland's obligations under European human-rights instruments. A real risk of a fair-trial violation, detention conditions incompatible with human dignity, or persecution of a recognised protected group can each ground a refusal. Again: the argument is only as strong as the evidence behind it.
Refugee and asylum status carries particular weight. A person who holds refugee status or who has applied for asylum in Poland or another EU state is, in principle, protected by the non-refoulement principle. That protection does not automatically defeat the extradition request – courts examine the relationship between the status determination and the specific allegations – but it is a substantial procedural shield and must be pleaded correctly.
In a recent matter (a CIS-origin request, autumn 2024), we assisted in arguing that the underlying prosecution was politically motivated, presenting documentary evidence of selective enforcement and procedural irregularities in the requesting state. The Polish court declined to order surrender after finding that the fair-trial guarantee could not be assured.
How does a Red Notice interact with the Polish court proceedings?
The Red Notice is, in most cases, the mechanism that triggers detention in Poland – but the two processes, INTERPOL review and national court proceedings, operate on different tracks and must be run in parallel, not sequentially. Waiting for a CCF decision before instructing Polish counsel is one of the most costly errors we see.
A Red Notice is circulated through INTERPOL's system by the requesting state's national central bureau. It reaches Polish border and law-enforcement systems and triggers the provisional detention that the extradition procedure then processes. The notice is not a court order. Poland decides whether to arrest and whether to surrender under its own domestic law. The notice is the trigger, not the authority.
Challenging the notice at the CCF level – under the data-accuracy and data-quality requirements of the RPD (INTERPOL's Rules on the Processing of Data), or on Article 2 or Article 3 grounds – can be transformative. A CCF deletion removes the INTERPOL-level alert and deprives the extradition request of its most visible international dimension. But the CCF's deletion process is, under the applicable rules, to be decided within nine months of the request being found admissible, and that timeline rarely fits the urgency of a live detention in Poland. The CCF track must run alongside the court proceedings, not instead of them.
In an extradition matter in Central Europe (spring 2025), we ran both tracks simultaneously: a CCF deletion request on data-accuracy grounds, and a court-level challenge to dual criminality and fair-trial conditions. The court proceedings concluded first, with surrender refused. The CCF process continued and the notice was subsequently deleted at source. A court result alone would not have removed the notice; a CCF result alone would not have protected the client during the live detention period.
There is an important asymmetry here that clients often miss. Deleting the notice at source – at INTERPOL level – is a different legal result from a Polish court refusing surrender. The court refusal protects you in Poland and, in principle, creates a record relevant to other EU states. But the notice may remain live in INTERPOL's system and continue to surface at borders elsewhere. Both results are needed, and they must be sequenced correctly.
A diffusion – an alert circulated directly by a national central bureau outside the formal Red Notice system – creates similar practical exposure but follows slightly different procedural tracks. Diffusions can also be challenged before the CCF, and their basis in the RPD's data-accuracy requirements is the same analytical starting point.
What actually determines the outcome of an extradition defence in Poland?
The quality of the file. That is the honest answer, and it is worth being precise about what it means.
Polish courts deciding extradition matters apply their own national procedure, and they are neither hostile nor sympathetic to extradition requests as a category. They follow the evidence and the law. A defence that arrives at the first hearing with complete documentary evidence of political motivation, a carefully argued dual-criminality analysis, and a properly pleaded human-rights submission will be heard on its merits. A defence that asserts those things without evidential foundation will not succeed, and it will make the appeal harder.
Sequencing is the second variable. The moment of arrest is the worst time to begin assembling a file. In our experience, clients who reach us before a trip to Poland – or immediately on detention, before the first hearing – are in a materially better position than those who contact us weeks in. The provisional arrest clock runs from the moment of detention, and the window for the strongest arguments is narrow.
The interaction between the national proceedings and the CCF file is the third variable. A CCF submission filed after a court refusal carries less procedural weight in some respects. A submission that is designed from the outset to reinforce both the INTERPOL challenge and the court arguments – sharing evidence, coordinating timing – is demonstrably stronger. We structure both files together wherever possible.
One honest limitation: the Polish appellate process takes time, and some requesting states are persistent. A first-instance refusal of surrender does not guarantee that the matter ends there. Tracking the case through the appellate stages, and monitoring whether the notice remains live in INTERPOL's system, is part of a complete defence.
The steps above are the general picture. Your situation depends on the specific request, the requesting state, the allegations, and the stage you are at now – which is precisely what an assessment examines.

Common mistakes in Polish extradition proceedings
The single most damaging mistake is treating the first hearing as procedural. It is not. The record created at that hearing – what is argued, what is conceded, what documents are placed before the court – shapes every subsequent step. Arguments not made at the first hearing require leave to raise later, and that leave is not always given.
The second is assuming that a Red Notice challenge will resolve the extradition. As noted above, the two tracks are parallel, not sequential. A CCF deletion does not automatically terminate domestic proceedings that are already under way. Both tracks must be managed.
The third is underestimating the human-rights evidence threshold. Courts do not refuse surrender on the basis of general assertions about the requesting state. They require specific, documentary evidence: decisions of international bodies, individual case histories, up-to-date country-conditions reports from credible institutional sources. Generic submissions carry little weight.
The fourth – and this applies particularly to clients who have already had a first CCF request refused – is assuming there is nothing further to do. There is no appeal against a CCF decision, but a fresh request is possible where new elements are available. A court-level result in Poland, if favourable, can itself constitute a new element that changes the INTERPOL analysis. The absence of an appeal route is not the end of the road; it means the next submission must be built more carefully.
A practical note on banking: when a Red Notice is live, banks in Poland and across the EU frequently close accounts or freeze access without prior notice. That is a consequence of the INTERPOL alert, not a separate legal process, and it does not resolve automatically when the notice is deleted. Evidencing the deletion to the institution – and sequencing that communication correctly with the CCF file – is a distinct step that is easy to overlook.
What is the realistic prospect for a non-EU requesting state?
The requesting state's relationship with EU legal standards is a significant factor. Requests from states with functioning independent judiciaries and comparable criminal procedure protections are examined on their merits. Requests from states where the independence of the prosecution and judiciary is in documented doubt face a higher bar, because Polish courts must satisfy themselves that the fair-trial guarantee is real and not formal.
This does not mean requests from difficult jurisdictions always fail. It means the evidentiary threshold for the requesting state is higher, and the arguments available to the defence are broader. In practice, requests from certain CIS-origin jurisdictions, and from some MENA-region states, have a weaker record before Polish courts than requests from states with comparable legal systems.
Ne bis in idem – the principle that a person may not be prosecuted twice for the same offence – is a recognised ground. If proceedings for the same conduct have been concluded in Poland or in another EU state, that prior determination is directly relevant and must be pleaded at the first opportunity.
The rule of specialty deserves mention too. Even where surrender is ordered, the requesting state is, under the applicable extradition rules, restricted to prosecuting the person for the offences that formed the basis of the extradition. Offences added after surrender are outside the authorised scope. This is both a limitation on what the requesting state can do after surrender and an argument in the defence: if the charges are likely to expand after the person arrives, that anticipated breach is relevant to the court's assessment.
If a prior CCF request or an earlier court proceeding did not produce the result sought, a second reading of the file – focused on what was missed and whether new elements exist – is the starting point. There is no appeal against a CCF decision, so any review must be built on new and specific grounds. That assessment is done before any further step is taken.

How we work on Polish extradition matters
We are an independent international boutique. We act before the CCF and in extradition proceedings abroad, coordinating with allied counsel in the country of detention. We have no affiliation with any domestic network in any requesting state, which matters when the notice originates from a jurisdiction where independence is not guaranteed.
We assess grounds honestly before we take a matter on. In our practice, we do not accept instructions where we do not see real grounds, and we tell clients that plainly at the assessment stage. We act only on lawful mandates; we do not assist anyone in evading legitimate justice.
In Polish extradition matters, our work typically involves coordinating the CCF file and the court strategy from the outset, ensuring that evidence assembled for one track reinforces the other. We work with allied counsel in Poland on the domestic hearing, and we manage the INTERPOL track independently.
No honest lawyer guarantees the outcome of an extradition proceeding or a CCF review. We are wary of anyone who does. What we offer is a careful assessment of the grounds, a well-structured file, and experience of where the arguments are strongest and where they are not.
The first assessment is confidential. Our enquiry form does not require your real name, and you can reach us through a secure channel – Signal, Telegram or WhatsApp – as well as by email at info@northlarkfirm.com.

Frequently asked questions
What happens at a first extradition hearing?
The first hearing is where the court confirms or lifts provisional arrest, sets any bail conditions, and receives initial submissions from both sides. It is not a full merits hearing, but the arguments placed on the record at this stage – on dual criminality, human rights and the characterisation of the alleged offence – shape the entire proceedings. A weak first hearing is difficult to correct on appeal, which is why immediate instruction of counsel is critical.
Can extradition be refused on human-rights grounds?
Yes. Polish courts can and do refuse surrender where there is a real risk of a fair-trial violation, detention conditions incompatible with human dignity, or persecution of a recognised protected group. The argument must be supported by specific, documentary evidence – decisions of international bodies, up-to-date country-conditions material and, where possible, individual case histories. General assertions without evidential foundation carry very limited weight. Article 2 of INTERPOL's Constitution, requiring respect for human rights, reinforces the same analysis at the INTERPOL level.
How does the Red Notice affect the request?
The Red Notice is typically the mechanism that triggers detention in Poland, but it is not the legal authority for surrender – that authority comes from the extradition request and the court order. Challenging the notice before the CCF and challenging the extradition request before the Polish court are separate processes that must run in parallel. A CCF deletion removes the INTERPOL-level alert, which is a distinct and durable result. A court refusal of surrender does not automatically delete the notice from INTERPOL's system.
