Extradition from Spain to Russia: defending against a Red Notice

On paper, a Russian extradition request routed through Spain looks like a routine matter of treaty obligation and judicial process. In substance, the file often tells a very different story – and the window to act effectively is shorter than most people expect.

Extradition from Spain to Russia is governed by the bilateral extradition treaty between the two states, interpreted against Spain's constitutional protections and the European Convention on Human Rights. A Red Notice 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. It does not oblige Spain to surrender anyone; Spanish courts decide under Spanish law, and the grounds to resist are real and regularly applied.

As of mid-2025, practitioners working this corridor see a consistent pattern: the human-rights and dual-criminality defences are not formalities. This page examines the treaty basis, the defences that actually work, the interaction with INTERPOL's notice mechanism, and the realistic picture of what the process involves.

What is the treaty basis for a Russian extradition request to Spain?

Russia and Spain are parties to a bilateral extradition treaty, which provides the formal channel through which Russia can request the surrender of an individual detained on Spanish territory. That treaty, like most bilateral instruments of its kind, is not self-executing. Spain's courts apply it through Spanish extradition law – the procedural rules that govern admissibility, the conduct of hearings, and the grounds on which surrender may be refused.

The treaty sets a dual-criminality requirement: the alleged conduct must constitute a criminal offence under both Russian and Spanish law. It also contains standard exclusion clauses. Political offences fall outside the scope of the obligation to surrender. Military offences and offences where there is a risk that the person will be tried again for a previously judged matter are treated separately.

What practitioners observe, in our experience of this corridor, is that Russian requests frequently arrive framed as economic crime – fraud, embezzlement, misappropriation. The framing matters. Conduct that constitutes a routine commercial dispute, or that involves alleged obligations under Russian law with no meaningful equivalent in Spain, may fail the dual-criminality test at the threshold stage. That argument must be made early, and made precisely.

The formal treaty channel and the INTERPOL mechanism are distinct. A Red Notice does not give the treaty any additional force. It does, however, create practical urgency: a provisional arrest triggered by a Red Notice starts a statutory clock under Spanish law, within which the formal extradition request must arrive and within which the first substantive hearing is held.

How does a Red Notice interact with the extradition process in Spain?

The Red Notice is INTERPOL's alert to national law-enforcement agencies, requesting them to locate and provisionally detain a person with a view to extradition. When a person subject to a Russian Red Notice is identified in Spain – at a border, during a routine check, or through other means – Spanish authorities may provisionally arrest that person under domestic law.

That provisional arrest triggers the process. The formal extradition request must follow within a defined period under the treaty. If it does not arrive in time, or if the request is incomplete, the basis for continued detention weakens significantly. In our practice, we have seen cases where the speed of the response in the first 48 to 72 hours determined whether that window was used to maximum effect.

The Red Notice itself is subject to challenge before the Commission for the Control of INTERPOL's Files – the CCF. Under INTERPOL's Constitution, Article 3 bars the processing of notices connected to offences of a political, military, religious or racial character. Article 2 requires that INTERPOL's activity respect human rights. Where the underlying Russian prosecution is politically motivated, selective, or connected to a commercial dispute dressed as criminal conduct, those provisions provide a route to challenge the notice directly.

A deletion or correction request submitted to the CCF is to be decided within nine months of the request being found admissible. An access request – to understand what data INTERPOL actually holds – is to be answered within four months. There is no appeal against a CCF decision; a fresh request requires new elements. That is why the quality of the first CCF file matters as much as any argument at a Spanish hearing.

Every week the notice stands, the underlying file hardens. The extradition proceedings in Spain move forward, evidence is marshalled on the requesting side, and the opportunity to shape the procedural record narrows. Both fronts – the CCF challenge and the Spanish court defence – require attention simultaneously, not sequentially.

What are the human-rights defences available in Spanish courts?

Spain's extradition law and its constitutional framework both permit refusal of surrender where there is a real risk that the person's rights under the European Convention on Human Rights will be violated in the requesting state. This is not a theoretical protection; Spanish courts have applied it in practice on the Russian corridor.

The relevant grounds include: the risk of torture or inhuman or degrading treatment in Russian detention; the absence of a fair trial guarantee, particularly where the prosecution is politically connected; and the risk that the person's situation will deteriorate on grounds of race, religion, nationality or political opinion – a condition that overlaps directly with Article 3 of INTERPOL's Constitution.

In our experience before similar bodies and in allied proceedings, the critical factor is evidence. A general assertion that Russian prisons are poor or that Russian courts are unreliable is not enough. The file must show, specifically, that this person, facing this prosecution, in these circumstances, faces a real individual risk. Country-conditions evidence, expert material, and documented patterns of selective prosecution in the relevant sector or region are what move courts.

The interaction with refugee or asylum status is significant. Where a person has been granted asylum or refugee status in Spain – or in another EU or Council of Europe state – that recognition creates a strong presumption against surrender. Non-refoulement, as a principle of both international refugee law and human-rights law, runs directly against extradition to the state from which protection was sought. Spanish courts take that seriously.

In a matter we handled on the CIS corridor (autumn 2024), the extradition request was refused at the first contested hearing after the court accepted that the prosecution's stated basis did not withstand scrutiny under the dual-criminality requirement and that the individual-risk showing, supported by detailed country-conditions material, met the human-rights threshold. No surrender took place.

Does dual criminality actually work as a defence in practice?

Dual criminality is a genuine threshold, not a formality, and it does succeed. The analysis requires a careful comparison of the conduct alleged – not the label attached to it by Russian prosecutors – with the elements required under Spanish criminal law for the nearest equivalent offence.

Russian economic criminal law is broad. Conduct charged as embezzlement of company funds, for instance, may on examination amount to a shareholders' dispute over distribution rights, or a contractual disagreement about revenue allocation. Spanish law does not criminalise every act that Russian law reaches. Where the gap is clear and evidenced, dual criminality fails and the request cannot proceed.

The practical difficulty is that the analysis must be done thoroughly, with proper attention to both the Russian statutory elements and the Spanish equivalents. A surface-level comparison that focuses only on the charge heading rather than the underlying conduct will not persuade a Spanish court. We coordinate with allied counsel in Spain on this analysis as a matter of course.

A second, less commonly argued but sometimes powerful point concerns the rule of specialty. Even where surrender is granted, it is only on terms that the requesting state may prosecute the person for the offence for which surrender was made. If Russia then charges additional offences not covered by the extradition request, the rule of specialty provides a further line of defence – though one that operates after surrender rather than before, and that therefore depends on the requesting state's own compliance.

In a matter on the MENA-to-Spain corridor (spring 2025), dual criminality was the decisive argument. The conduct alleged under the requesting state's law had no meaningful Spanish equivalent when the statutory elements were examined in full. The request was refused before it reached the human-rights analysis.

What are the most common mistakes in defending this corridor?

The first and most damaging mistake is delay. A person who learns of a Red Notice – or who is provisionally arrested – and waits to see what happens loses the window in which the procedural record is most open. The first hearing in Spanish extradition proceedings is the point at which bail conditions, the scope of the initial detention, and the timetable for the full hearing are set. Appearing at that hearing without prepared arguments is a serious disadvantage.

The second mistake is treating the CCF application and the Spanish court proceedings as alternatives rather than as parallel processes. They serve different purposes. A CCF deletion may remove the alert and reduce the risk of future arrest; it does not automatically stop extradition proceedings already under way. A successful human-rights defence in a Spanish court does not delete the underlying INTERPOL data. Both must be pursued, and they must be sequenced carefully so that arguments made in one forum do not prejudice the other.

The third mistake – one we see regularly – is the filing of a weak CCF request at the outset. Filing to the CCF without professional advice rarely produces a different result than not filing at all. The Commission applies INTERPOL's own rules with care; a submission that does not engage with the specific provisions of the RPD's data-accuracy and data-quality requirements, or that fails to substantiate the political-character argument under Article 3 of the Constitution, will not succeed. And there is no appeal. A fresh request after refusal requires new elements, and a weak first file raises the threshold for any review.

The fourth mistake is conflating a Russian internal arrest warrant with the international dimension. Russia's domestic investigative measures do not have extraterritorial legal force in Spain. The question for a Spanish court is what the treaty requires and what Spanish law permits – not what Russia's own processes have decided.

How do we approach the Spain-Russia corridor?

In our practice, this corridor demands work on two tracks simultaneously. The first track is the INTERPOL mechanism: assessing what data INTERPOL holds, whether a Red Notice or diffusion is active, and whether the grounds under INTERPOL's Constitution and the RPD support a deletion request. We build that file to the standard the CCF actually requires, not to the standard that feels sufficient.

The second track is the Spanish proceedings themselves. That work is conducted in coordination with allied counsel in Spain – practitioners with direct standing before the Spanish courts and familiarity with the extradition bench. Our role is to provide the INTERPOL and international dimension: the country-conditions analysis, the political-character argument, the human-rights framing, and the coordination of the CCF submission with the court timeline.

The honest picture on prospects: this corridor is not one where outcomes can be guaranteed. Courts weigh evidence, and some cases are stronger than others. A prosecution that is demonstrably politically motivated, connected to a corporate dispute, or directed at a person who has received refugee protection has stronger ground than one that looks, on the face of the file, like a conventional economic-crime allegation. Where the grounds are real, the defences are real. Where the file is weak, we say so before engagement, not after.

We act only on lawful mandates. Where we see genuine grounds, we act on them. Where the case does not support the defences described here, we will say that plainly in a first assessment.

The steps above are the general picture. Whether any of these routes applies in a specific case depends on the file, the Russian prosecution, and the stage of the Spanish proceedings – which is precisely what a confidential assessment addresses.

Common misconceptions about this corridor

The most persistent misconception is that a Red Notice carries the same legal force as an arrest warrant. It does not. A Red Notice is a request, not a judicial order. Spanish courts are not bound to surrender anyone on the basis of a notice alone. The decision is made under Spanish law, at a Spanish hearing, by Spanish judges applying the treaty, the Constitution, and Spain's human-rights obligations.

A related misconception is that once extradition proceedings begin, the outcome is inevitable. It is not. Spanish courts refuse extradition requests in appropriate cases, including on this corridor, where the human-rights or dual-criminality arguments are properly made and evidenced.

The third misconception – relevant to the CCF dimension – is that filing a request yourself, without professional preparation, is a reasonable first step. The CCF's process is not designed to be inaccessible; formally, any individual may apply. But the outcome turns entirely on the quality of the legal argument. A submission that does not engage with INTERPOL's own data rules, that asserts a conclusion without substantiating the premise, will not be treated differently from any other unsubstantiated submission. And, as noted, there is no appeal – only a review requiring new elements.

Frequently asked questions

What happens at a first extradition hearing?

At a first extradition hearing in Spain, the court considers whether the formal conditions for provisional detention are met and sets the procedural timetable. This is the moment at which bail conditions are argued and the scope of initial detention is defined. It is also the point at which a prepared defence has its greatest early impact – arriving without arguments ready is a significant disadvantage. Allied counsel with standing before the Spanish court must be instructed before this hearing, not after.

Can extradition be refused on human-rights grounds?

Yes. Spanish law and Spain's obligations under the European Convention on Human Rights permit refusal of surrender where there is a real, individual risk of torture, inhuman treatment, or an unfair trial in the requesting state. The ground is not theoretical: Spanish courts have refused extradition requests where the human-rights showing was properly evidenced. A general assertion is insufficient; the file must demonstrate the specific risk to this person, in these circumstances, facing this prosecution.

How does the Red Notice affect the request?

A Red Notice may trigger provisional arrest in Spain, which starts a statutory clock within which Russia must submit the formal extradition request. The notice itself does not create any extradition obligation; that obligation arises, if at all, from the treaty. Separately, the notice can be challenged before the CCF on grounds under INTERPOL's own Constitution and its Rules on the Processing of Data. A successful CCF deletion reduces the risk of future arrest but does not automatically stop Spanish proceedings already under way.
