Extradition from Spain to Kazakhstan: defending against a Red Notice

A client contacts us from Spain. There is a Red Notice in the system, a Kazakhstani extradition request is either anticipated or already lodged, and the question is the same every time: how serious is this, and what can actually be done? As of spring 2025, the Spain–Kazakhstan corridor is one we see regularly. The answer depends on the treaty basis, the nature of the underlying charge, and the human-rights position in Kazakhstan itself.

Extradition from Spain to Kazakhstan is legally possible but subject to meaningful legal constraints. A Red Notice in this corridor is a request to locate and provisionally detain a person with a view to extradition – it is not an arrest warrant and not a judicial decision. The applicable Spanish extradition law and international human-rights instruments together give Spanish courts real grounds to refuse surrender, and in our practice before the CCF and in European extradition proceedings, those grounds are often present in Kazakhstani-origin matters.

This analysis covers the treaty basis for the corridor, the defences that carry weight in Spanish proceedings, the role of the Red Notice and how to challenge it at the CCF, and the honest prospects in a case of this kind.

What is the treaty basis for extradition between Spain and Kazakhstan?

Spain and Kazakhstan have not concluded a bilateral extradition treaty. That absence is significant. In the absence of a treaty, Spain will decide whether to extradite on the basis of its domestic extradition law, applying the principle of reciprocity and the conditions that law imposes. A requesting state without a treaty relationship cannot rely on a pre-agreed framework to ease the path of a request. Each condition in the Spanish extradition law must be met independently, and Spanish courts examine them closely.

Kazakhstan is not a member of the European Union. The EU's mutual recognition instruments – which operate on presumptions of trust between member states – do not apply. Spain therefore treats a Kazakhstani request as a request from a third state, applying its own national law in full.

What this means in practice is that the requesting state carries a heavier evidential burden than it would in an intra-EU matter. The charge must correspond to a criminal offence under Spanish law. The documents must be translated and authenticated. The procedural safeguards must be demonstrated. In our experience, Kazakhstani requests frequently fall short on one or more of these conditions, and the gap is not always easy to cure.

Does dual criminality apply, and why does it matter here?

Dual criminality is a fundamental condition: the conduct alleged must constitute a criminal offence in Spain as well as in Kazakhstan. This is not a formality. The analysis is conducted on the underlying facts, not on the name given to the offence by the requesting state.

Kazakhstan prosecutes conduct under headings that sometimes have no direct equivalent in Spanish criminal law – fraud, embezzlement and economic offences, in particular, are framed in the Kazakhstani national criminal code in ways that can exceed or diverge from the equivalent Spanish category. Where the conduct as described does not satisfy the dual-criminality test under Spanish law, surrender must be refused.

We have seen requests in this corridor characterised as large-scale economic crime that, on analysis, describe conduct that is civil rather than criminal in Spain. A careful reading of the underlying factual allegations – not simply the formal charge – is the starting point for any dual-criminality defence.

A related issue is political motive. Article 3 of INTERPOL's Constitution bars the processing of notices linked to offences of a political, military, religious or racial character. At the extradition stage, the Spanish courts apply a parallel analysis: political offences are excluded from extradition. In Kazakhstani-origin matters, the distinction between a genuine commercial prosecution and a politically-driven one is often material, and we address this explicitly below.

How does the Red Notice interact with an extradition request?

A Red Notice and an extradition request are separate legal instruments, but they operate in sequence. The notice is used to locate and provisionally detain a person while a formal extradition request is prepared. Once Spain detains a person on the basis of a Red Notice, a statutory window begins within which the requesting state must lodge the formal request. If it does not, the person must be released.

The notice itself can be challenged independently before the CCF. A successful CCF challenge – deletion or correction of the underlying data – does not automatically stop an extradition request already in motion. But it undermines the requesting state's position materially. A court examining a surrender request in parallel with a CCF deletion is looking at a weaker file on both fronts simultaneously.

Conversely, a weak first CCF file can prejudice the extradition defence. There is no appeal against a CCF decision. A fresh request requires new elements. Presenting an unconvincing file to the CCF first, and then trying to rely on the same arguments in the Spanish extradition proceedings, is a pattern we see in cases that were not handled strategically from the outset. Every week the notice stands, the underlying file in Spain is treated as active and the clock on formal extradition runs.

In autumn 2025, in a matter we handled involving a CIS-origin Red Notice, we filed simultaneously before the CCF on data-accuracy grounds and before the Spanish court on dual-criminality and human-rights grounds. The sequencing of those two filings, and the evidence used in each, was coordinated from day one. The result was a deletion at the CCF before the extradition hearing reached its substantive stage.

Are there genuine human-rights grounds in a Kazakhstan extradition?

There are, and in our assessment they are among the strongest in this corridor. Article 2 of INTERPOL's Constitution requires that INTERPOL's activity respect human rights, in the spirit of the Universal Declaration of Human Rights. Spanish extradition law imports the same standard through the European Convention on Human Rights and the Spanish Constitution itself. A court may refuse extradition where there are substantial grounds to believe that the person would face a real risk of ill-treatment, an unfair trial, or persecution on account of their political opinions, ethnicity or religion.

Kazakhstan is a party to the principal international human-rights instruments, but independent monitoring bodies and established reporting have consistently documented patterns of concern: the independence of the judiciary from executive influence, conditions of pre-trial detention, the use of extended detention pending trial, and the prosecution of business disputes through the criminal justice system. These are not abstract concerns. They are the building blocks of a human-rights defence in Spanish proceedings.

The defence requires evidence. A generic assertion of poor conditions is insufficient. What works is a file that documents the particular risk to this individual – the nature of the charge, the identity of the complainant, the pattern of prosecution in analogous cases in Kazakhstan, and the individual's specific profile (political associations, business interests, or prior contact with the authorities).

In a spring 2025 extradition matter we handled in Southern Europe involving a Central Asian requesting state, the request was refused before surrender on human-rights grounds. The court found that the documented pattern of judicial interference in cases of that type, combined with the individual profile of the applicant, satisfied the threshold for refusal. The evidence was assembled over several months before any detention occurred.

What role does refugee or asylum status play?

Where a person has been recognised as a refugee in Spain or holds equivalent protection status in another EU member state, extradition to the country of persecution is barred. The principle of non-refoulement – the obligation not to return a person to a territory where they face serious risk – applies with direct force in Spanish law.

Asylum proceedings and extradition proceedings run on parallel tracks, and the interaction between them is important. An asylum application does not automatically stay extradition, but a positive asylum decision, or a finding of fear of persecution, creates a strong barrier to surrender. Where a client has not yet applied for asylum but the facts would support a claim, early advice on sequencing is essential. Filing an asylum claim after a provisional arrest is possible but less orderly than preparing the position in advance.

Similarly, where the person has previously faced criminal proceedings in Kazakhstan or in a third state for the same underlying conduct, the principle of ne bis in idem – no person shall be tried twice for the same offence – may apply. This is a ground for refusal under Spanish law and under the international instruments Spain applies.

What are the common mistakes, and what should you not do?

The most damaging mistake we see is inaction. A person becomes aware of a Red Notice or of a risk of provisional arrest and decides to wait, hoping the matter resolves itself. It does not. The formal extradition request is prepared in the background, the notice remains active and visible, and any travel within or outside Spain carries arrest risk.

The second mistake is handling the CCF request and the extradition defence as separate matters, often with different lawyers who do not coordinate. The two tracks interact. Arguments made in one proceeding are visible to the other side and can be used against the client in the parallel file. Inconsistency between a CCF submission and a statement in extradition proceedings is a point that opposing parties exploit.

The third mistake is filing a weak first CCF request. There is no appeal against a CCF decision. A poor first file – one that asserts political motive without evidence, or challenges data accuracy without documentation – is difficult to recover from. The absence of an appeal mechanism means the first submission must be built properly or not at all.

Finally, do not assume that Spanish courts will automatically resist Kazakhstani requests. They will apply the law, and where a request is formally compliant and the dual-criminality and human-rights conditions are satisfied on the papers presented to them, courts will proceed. The quality of the defence depends on the quality of the file put before the court.

What is the honest assessment of prospects in this corridor?

Prospects in the Spain–Kazakhstan corridor are genuinely better than in some other corridors, for structural reasons. There is no bilateral extradition treaty. Kazakhstan is not an EU member. The human-rights conditions on the ground provide real grounds for a well-evidenced refusal. Dual criminality is a meaningful test that Kazakhstani requests frequently struggle with.

None of that means refusal is automatic or guaranteed. Courts examine each case on its facts. A strong extradition request, in which Kazakhstan provides complete documentation, demonstrates dual criminality cleanly, and addresses human-rights concerns on the face of the papers, will receive serious consideration. The defence must be equally rigorous.

In our practice, the cases that produce the best outcomes are those where a full assessment is conducted before any detention occurs. Pre-emptive CCF work, early asylum or protection analysis, and coordination with allied counsel in Spain – all before the provisional arrest – give the file the depth it needs. A reactive defence, assembled after detention, is harder and more pressured.

We assess grounds honestly before we take a matter on. Where the grounds are thin, we say so. Where they are strong, we build the file systematically across both the CCF and the extradition proceedings.

Frequently asked questions

What happens at a first extradition hearing?

At the first hearing in Spain, the court confirms identity, establishes that a formal extradition request or a Red Notice-based detention request is in order, and hears initial submissions on whether provisional detention should continue. The requesting state is not usually represented in person. Defence counsel must be present and ready to argue any immediate grounds – dual criminality, human rights, or status – because the detention decision at this stage is consequential and urgent. The window to act is short.

Can extradition be refused on human-rights grounds?

Yes. Extradition can be refused where there are substantial grounds to believe the person faces a real risk of ill-treatment, an unfair trial, or persecution in the requesting state. In Spain this flows from the European Convention on Human Rights and Spanish constitutional law. The standard requires credible, specific evidence rather than a general assertion. In Kazakhstani-origin cases, documented patterns of judicial interference, detention conditions and the profile of the individual regularly satisfy this standard when properly argued and evidenced.

How does the Red Notice affect the request?

The Red Notice is used to trigger provisional arrest while a formal extradition request is assembled. It is not itself a legal basis for surrender – that requires a separate, formal extradition procedure. However, a notice in the system gives the requesting state a live enforcement tool, creates travel risk, and signals to Spanish authorities that a request is likely. A successful CCF challenge to the notice materially weakens the parallel extradition file. The two proceedings should always be managed in coordination, not separately.
