A diffusion circulated by Ukraine's national bureau can reach border agencies, police forces and financial institutions across dozens of countries within hours. As of early 2026, the volume of Ukrainian-origin alerts in INTERPOL's system has grown considerably, a direct consequence of the ongoing armed conflict and the displacement of millions of people, many of whom now live and travel under a different jurisdiction's scrutiny. If your name appears on one of these alerts, a single border check can turn into a provisional arrest before you have had the chance to explain anything.
An INTERPOL diffusion from Ukraine is an alert circulated directly by Ukraine's National Central Bureau, outside the formal Red Notice system. It is not an arrest warrant and not a judicial decision. It can be challenged before the Commission for the Control of INTERPOL's Files (CCF) on grounds drawn from INTERPOL's own Constitution and the Rules on the Processing of Data (RPD), and in our practice the data-quality and political-character grounds are the most frequently engaged for Ukrainian-origin material.
This analysis explains how a diffusion differs from a notice, what grounds apply, how the CCF route works in practice, and where the realistic limits lie.
How does a diffusion from Ukraine differ from a Red Notice?
The distinction matters because the procedural route and the legal arguments differ at several points. A Red Notice is formally published by INTERPOL's General Secretariat after a review against the organisation's own compliance criteria. A diffusion bypasses that centralised step entirely. Ukraine's National Central Bureau sends the alert directly to the NCBs of selected member states, attaching whatever the bureau chooses to include.
That direct-circulation model has two consequences. First, the data in a diffusion has received less pre-publication scrutiny. Defects that might have been caught at the Secretariat – a missing dual-criminality analysis, a category of offence touching on Article 3 of INTERPOL's Constitution – can reach a member state's database before anyone has reviewed them. Second, a diffusion can be harder for the subject to detect. There is no entry on the public INTERPOL website, so the person named is often unaware until a border or a bank makes the problem visible.
Both instruments can be challenged before the CCF. A diffusion is explicitly covered by the CCF's mandate under the RPD, and deletion of a diffusion follows the same procedural path as deletion of a notice. The grounds are the same; the file-building discipline must be equally rigorous.
What does the Ukrainian conflict mean for diffusion practice?
Ukraine has been under martial law since February 2022. That context does two things that practitioners before the CCF need to hold in mind simultaneously. On one side, Ukraine's law-enforcement and judicial system has continued to function in parts, and a diffusion from Kyiv is not automatically invalid simply because the country is at war. On the other side, the conditions of active conflict raise genuine questions about the reliability of data, the independence of individual prosecution decisions and the ability of a subject to access procedural rights in Ukraine itself.
In our CCF practice, we have seen Ukrainian-origin material challenged successfully on data-accuracy grounds: a criminal case file that was closed or altered after the alert was sent, a charge that was reclassified, or a person whose status changed following displacement. We have also seen cases where the Article 3 political-character argument was the primary line, particularly where the underlying dispute involved assets, corporate control or conduct that predates the conflict but was recharacterised under emergency legislation.
What we do not do is file a blanket political-character argument for every Ukrainian-origin alert. Article 3 of INTERPOL's Constitution sets a genuine threshold: the offence itself, or the prosecution's purpose, must be of a political, military, religious or racial character. Asserting that threshold without evidence is the single most reliable way to lose a CCF file and foreclose the review options that remain.
The conflict also affects the cross-border reality. A person who left Ukraine and now lives in the EU, the Gulf or North America may face the diffusion in two directions simultaneously: the alert active in their country of residence, and a potential extradition framework that must be assessed under the domestic law of the state where they now live. Those two problems require coordinated responses, not sequential ones.
What are the principal grounds to challenge a Ukrainian-origin diffusion?
The CCF applies INTERPOL's own rules, not Ukrainian criminal law. That is the starting point for every argument.
The main lines of challenge are as follows.
Data accuracy under the RPD. The RPD's data-accuracy and data-quality branches require that any information INTERPOL processes must be accurate, up to date and proportionate to the legitimate purpose it serves. A diffusion based on charges that have since been withdrawn, a warrant that has lapsed, or a case file that no longer reflects the subject's actual procedural position fails this standard. Evidence of those changes – procedural documents, status updates, judicial orders – is the foundation of this argument. It requires active document gathering, which is harder when the requesting state is at war and access to Ukrainian courts is limited. In those circumstances, allied counsel in the relevant jurisdiction becomes a practical necessity.
Political, military or racial character under Article 3. Article 3 of INTERPOL's Constitution bars INTERPOL from processing data in connection with any activity or offence that is of a political, military, religious or racial character. For Ukrainian-origin material, this argument arises most often where the underlying dispute is commercial or civil in origin and has been converted into a criminal matter through mechanisms that the conflict's legal emergency has made easier to deploy. It also arises where the subject belongs to an ethnic or linguistic minority group that has faced documented targeting. The argument must be evidenced. Public reporting, country-conditions materials, and documentation of the procedural history of the underlying case are all relevant.
Human rights under Article 2. Article 2 of INTERPOL's Constitution requires the organisation to act with respect for human rights, in the spirit of the Universal Declaration of Human Rights. In the CCF context, this ground is most useful where surrender to Ukraine would expose the subject to treatment that international human-rights standards prohibit. Evidence from independent monitoring bodies, UN reporting and reliable country-conditions documentation is the raw material here.
Procedural defects. A diffusion that does not meet INTERPOL's own processing conditions – because it lacks the required identifiers, the originating case does not meet the minimum sentence threshold, or the issuing state has not provided the information the RPD requires – can be challenged on purely procedural grounds, independently of the political-character or human-rights arguments. This is often the cleanest route, and it is underused.
In practice, the strongest files combine more than one of these lines. A procedural defect argument, even if successful on its own, addresses the notice rather than the underlying prosecution. A political-character argument, standing alone, requires a high evidential threshold. Together, they present the CCF with multiple independent reasons to act.
How does the CCF process work, and what are the realistic timelines?
The process begins with an access request: a formal submission to the CCF asking INTERPOL to confirm whether data is held about the subject and in what form. Under the applicable rules, an access request is to be answered within four months of receipt, though in practice delays occur. The access request establishes the factual basis for the challenge that follows.
Once the data is confirmed, a deletion request is filed. This is the substantive CCF submission: it sets out the grounds, presents the evidence, and asks the Commission to direct INTERPOL to delete or correct the data. A deletion request is, under the rules, to be decided within nine months of being found admissible. Again, that figure represents the standard rather than the universal experience.
There is one procedural reality that shapes everything else: there is no appeal against a CCF decision. If the Commission declines to delete the data, the only further route is a new request based on new elements. That means the first file is not simply the opening move in a negotiation. It is the primary opportunity, and a weak first file limits the options on any review. The question of what new elements might be available, and when, is something we assess before we advise a client to file at all.
The bridge from access to deletion to consequence-management is not automatic. While the CCF process runs, the alert remains active. Travel risk, banking exposure and visa complications continue. Managing those in parallel with the CCF file requires a sequenced plan, not parallel improvisation.
The steps above describe the general procedural shape. The specific file, the Ukrainian case details and the current status of the underlying proceedings are what an assessment actually looks at.

What should you not do after discovering a Ukrainian-origin diffusion?
The first instinct of many people is to contact the Ukrainian bureau directly, or to engage a Ukrainian lawyer to negotiate the withdrawal of the alert at source. In some circumstances, direct engagement in Ukraine is appropriate – for example, where the underlying case is genuinely capable of resolution there and the subject can safely participate. In other circumstances, it is the worst available move.
If the diffusion is politically motivated, direct engagement exposes the subject and their advisers without gaining anything. If the alert rests on a data defect, there is no reason to negotiate with the issuing bureau before the CCF has confirmed what data is actually held. And if the subject is a recognised refugee or holds asylum status in the country of residence, steps that imply acceptance of the Ukrainian jurisdiction's authority may affect the asylum position.
Equally, simply waiting is not a safe default. An alert does not lapse because the subject remains quiet. It accumulates: it is passed to more databases, it is acted on by more agencies, and its presence in a system becomes progressively harder to document and challenge.
The specific sequencing error we see most often is a weak, unsubstantiated first CCF submission filed quickly after the alert is discovered, often by a non-specialist. The Commission declines it. The subject then has no appeal. A review requires new elements that were, in many cases, available at the outset but were not assembled. A hasty first file is not better than a delayed good one. The preparation window is worth using.
How does a Ukrainian-origin diffusion interact with extradition risk?
A diffusion is not a formal extradition request. It does not, of itself, oblige the state of residence to surrender anyone. But it creates the alert infrastructure that makes a provisional arrest possible, and a provisional arrest is often the first step in an extradition process.
Ukraine has bilateral extradition treaties with many states and participates in multilateral conventions. The domestic extradition law of the requested state then governs whether surrender can proceed. That domestic law will apply its own tests: dual criminality, the political-offence exception, the human-rights and non-refoulement bars, and the rule of specialty. These are assessed by the courts of the state of detention, not by INTERPOL.
The interaction between the CCF file and an extradition defence is a sequencing question. In our practice, the CCF route and the domestic extradition defence run in parallel where a provisional arrest has already occurred. Where the subject is not yet detained, the CCF route takes priority because deletion of the data removes the alert that enables the arrest. Once detained, allied counsel in the country of detention must be engaged immediately, alongside the CCF file.
In a recent matter involving a Ukrainian-origin diffusion (a commercial dispute, Western Europe, winter 2025), deletion of the diffusion was obtained after the CCF found that the underlying data did not meet the RPD's data-accuracy requirements. The extradition request that had been filed simultaneously was subsequently withdrawn by the requesting state. That outcome – deletion followed by withdrawal – is one of the better scenarios. It is not guaranteed. But it illustrates why the two processes must be coordinated from the outset rather than addressed sequentially.
In a separate matter (CIS-connected, Gulf-region detention, spring 2025), a diffusion from the same bureau was challenged in parallel with a domestic habeas proceeding. The CCF file was not the fastest route in that case; the domestic proceeding produced a release from provisional detention first, and the CCF deletion followed several months later. The lesson: the fastest legally available route is not always the CCF, and the advice given must reflect that honestly.
Is a Ukrainian-origin diffusion the same as a politically motivated Red Notice?
This is a myth worth correcting directly. Many people equate any Ukrainian-origin alert with a politically motivated notice, and assume the political-character ground automatically applies. It does not.
Ukrainian prosecutors pursue genuine criminal matters alongside, and in some cases instead of, political prosecutions. A diffusion based on a straightforward fraud allegation, a corporate crime or a drugs matter may have no political dimension at all. Filing an Article 3 argument in that context is not only likely to fail; it may foreclose a cleaner procedural or data-quality argument that would have succeeded.
The reverse error also exists. A diffusion that looks routine on its face – an embezzlement charge, for example – may have been generated by a prosecution that is politically directed in a way that the surface documents do not reveal. That requires investigation of the underlying case history, the political context, and the profile of the subject and the alleged victim. The correct argument only emerges from that investigation.
No honest lawyer guarantees a CCF result, and you should be cautious of anyone who does. What we can honestly say is that the political-character argument is one of several tools, and the right tool depends on the facts of the specific file.

If an earlier challenge produced a refusal, or if you are assessing a Ukrainian alert for the first time and want to understand what the file actually shows, write to us at info@northlarkfirm.com. Where a first CCF request was refused, a review must identify what new elements exist before a second file is built. There is no appeal, so this step cannot be skipped.
Frequently asked questions
Is a Red Notice from this country politically motivated?
Not automatically. Ukrainian-origin notices and diffusions cover a wide range of offences, and many are not politically motivated. Whether Article 3 of INTERPOL's Constitution applies depends on the specific case: the nature of the offence, the procedural history, the profile of the parties, and the context in which the prosecution was initiated. The political-character argument requires evidence; it does not arise from the nationality of the requesting state alone.
Can I travel while the notice stands?
Travel while a Ukrainian-origin diffusion or Red Notice is active carries real risk. Each member state decides under its own law whether to act on an INTERPOL alert, and some states are more likely to detain than others. Certain routes – particularly through states with strong extradition relationships with Ukraine – carry materially higher risk. The safest position is to assess the specific alert and your intended travel before you move, not after.
What are the realistic grounds to challenge it?
The main grounds are: data-accuracy defects under the RPD (the information is wrong, outdated or disproportionate); political, military or racial character under Article 3 of INTERPOL's Constitution; human-rights concerns under Article 2; and procedural defects in the way the alert was issued. The strongest files typically combine more than one ground. The correct combination depends on the actual case file. No outcome can be guaranteed, and the quality of the first submission is critical because there is no appeal against a CCF decision.
