How to prepare for an extradition hearing

A single border check can turn into a provisional arrest. That is not a warning designed to alarm you – it is the operational reality of how INTERPOL alerts interact with national police systems. If an extradition request has already been made or you have reason to believe one is coming, the window between now and the first hearing is the most consequential period in the entire process. How you use it determines what options remain open.

Preparing for an extradition hearing means understanding, precisely, what the requesting state has filed, whether the request meets the legal standards of the state that holds you, and which grounds – dual criminality, human rights, the political character of the underlying prosecution, or a procedural defect in any associated INTERPOL notice – are available to resist surrender. A Red Notice is not an arrest warrant and not a judicial decision; it is a request to locate and provisionally detain with a view to extradition. That distinction matters because it opens a parallel track: challenge to the CCF, running alongside the court proceedings.

This guide sets out the preparation steps in the order they should be taken, the evidence that changes outcomes, the mistakes we see most often, and an honest account of what the process can and cannot achieve. As of mid-2025, the procedural landscape across different jurisdictions remains uneven, but the core steps below apply wherever you are detained or resident.

Step 1: Understand exactly what has been filed against you

The first and most immediate step is to obtain the full extradition package – the formal request, the underlying warrant or court order from the requesting state, and any translation. Do not assume your local lawyer has received everything. Extradition packages are sometimes incomplete on first service, and missing documents can be both a procedural advantage and a trap if you fail to notice the gap promptly.

Specifically, confirm the following at the outset:

• The offence or offences charged, as described in the requesting state's documents (not a summary).
• Whether a Red Notice, diffusion or other INTERPOL alert was used to locate you – and whether it is still active.
• The stated basis for the request: conviction-based or accusation-based.
• Any applicable treaty between the requesting and requested states, and whether the request complies with its formal requirements.

In our practice, we frequently see clients who have been told only that "INTERPOL is involved" without anyone having checked whether the underlying notice complies with INTERPOL's own rules. That matters, because a notice that violates Article 3 of INTERPOL's Constitution – the bar on politically-motivated processing – or that fails the RPD's data-accuracy requirements, weakens the entire chain on which the extradition depends.

Do not sign anything presented at the point of provisional arrest without specialist advice. Consents and waivers signed at that stage can close off procedural routes that would otherwise be available.

Step 2: Secure specialist counsel before the first hearing

Local counsel in the state of detention is essential, but not always sufficient. Extradition law combines procedural rules specific to the requested state, treaty obligations, and human-rights norms that operate at the international level. An adviser who handles only domestic criminal work will not have the full picture.

Where the extradition relates to a Red Notice – or where the arrest was triggered by an INTERPOL alert – you also need someone who can act before the CCF in parallel. The CCF process and the extradition hearing are formally separate. Neither automatically pauses the other. But a CCF deletion, or even a CCF finding of non-compliance, carries weight in the extradition court. In a MENA-origin matter in autumn 2024, the extradition court in the state of detention gave significant weight to the CCF's preliminary position on data quality when deciding whether provisional detention should be extended. That is the kind of sequencing that requires planning.

To identify whether you need parallel CCF representation, ask one question: was the arrest or detention triggered, even partly, by an INTERPOL alert? If yes, the two tracks should be opened at the same time. For more on that process, see our service on Red Notice removal.

What evidence actually changes the outcome of an extradition hearing?

Evidence of four things tends to move extradition courts in favour of refusal or release: human-rights risk in the requesting state; absence of dual criminality; a procedural defect in the request itself; and material showing the political character of the underlying prosecution. These are not mutually exclusive. In the strongest files, two or three are present together.

Human-rights evidence is not general commentary about conditions in the requesting state. Courts expect specific, documented material: country guidance from reliable institutional sources, evidence that the individual concerned has been targeted rather than prosecuted on general grounds, and any prior findings by international bodies. Assertions without evidence are given very little weight.

Dual criminality requires that the conduct alleged would constitute a criminal offence in the requested state if it had occurred there. This is a technical analysis. The offence label used by the requesting state is not determinative – the conduct itself is examined. Fraud allegations from states with unusually broad criminal codes, and tax or currency offences, commonly fail this test in jurisdictions with higher thresholds.

Article 3 of INTERPOL's Constitution bars the processing of data in connection with offences of a political, military, religious or racial character. If the same conduct that grounds the extradition request is the subject of an Article 3 challenge before the CCF, that parallel argument must be built with consistent evidence across both proceedings. Inconsistency between what you say to the CCF and what is argued in court is a serious error.

Procedural defects in the extradition request – expired warrants, missing certifications, failure to comply with treaty formalities – do not resolve the underlying problem but can buy time and, in some jurisdictions, lead to discharge. For a detailed treatment, see our grounds page on procedural defects.

Step 3: File an access request with the CCF immediately

If you do not yet know with certainty what data INTERPOL holds about you, file an access request with the CCF at the earliest opportunity. Under the applicable rules, INTERPOL must respond to an access request within four months. That is a meaningful deadline in the context of extradition proceedings, which in many jurisdictions move slowly in their early stages.

The access request tells you: whether a Red Notice, diffusion or other alert is live; which national bureau requested it; and whether any prior correction request has been made and refused. That information shapes the strategy for both the CCF track and the hearing itself.

For a client in Eastern Europe in spring 2025, the access response revealed that two separate diffusions had been filed – one of which we had not known about – by bureaux in different countries. The court proceedings in the state of detention had been structured on the assumption that only one notice existed. Correcting that assumption changed the procedural map entirely.

An access request is the foundation. It is not the same as filing for deletion. If you proceed to a deletion request, the CCF's rules provide for a decision within nine months of the request being found admissible. There is no appeal against a CCF decision, which means the quality of the first submission is the only submission that counts. For detail on how the CCF review process works, see our page on the CCF review service.

Step 4: Build and organise your documentary file

Courts and the CCF both receive far more documentation than they read carefully. The task of preparation is not to assemble everything that might be relevant – it is to build a file that makes the key facts and arguments impossible to ignore. That means structure, not volume.

A well-prepared file contains:

1. A clear factual chronology. When the prosecution commenced; when the notice was filed; when you were first alerted; what happened at each stage. Dates matter enormously for dual-criminality and specialty arguments.
2. Evidence on the political or improper character of the prosecution, where that ground is available. This might include: contemporaneous communications, evidence of prosecutorial selectivity, material showing the involvement of a private complainant with state connections, or documentation of parallel asset-recovery proceedings with no criminal foundation.
3. Human-rights country evidence, curated and specific, not generic.
4. Any prior CCF correspondence – access responses, inadmissibility decisions, prior deletion requests. These must be disclosed and integrated into the argument, not buried.
5. Personal status documents that are relevant to the requested state's law: refugee status, asylum grant, citizenship, family connections. These can engage non-refoulement or other personal-status defences that operate independently of the merits of the extradition request.

Organisation matters as much as content. A poorly organised file in which critical evidence appears at page 200 of an unsorted bundle may as well not exist. Every key document should be cross-referenced in the written argument.

What mistakes undermine an extradition defence?

The most common mistake is delay. A provisional arrest triggers statutory timelines in most jurisdictions, and the first hearing – often just a question of whether detention continues – sets the tone for everything that follows. Arriving at that hearing with no documentation, no specialist input, and no CCF access request in progress is almost impossible to recover from fully.

The second mistake is inconsistency across parallel proceedings. What you say to the CCF, what is argued in the extradition court, and what is said in any asylum or refugee claim must be consistent. We have seen cases in which a well-intentioned asylum application contained statements that directly damaged the Article 3 CCF argument. The two files should be prepared by people who are in communication with each other.

The third mistake is the myth that filing to the CCF yourself resolves the problem. A self-represented CCF submission is technically permitted. In practice, an inadequate first submission raises the difficulty of any later effort, because there is no appeal – only a review on new elements. Assembling genuinely new elements after a refusal requires a thorough understanding of why the first file failed. A weak initial file does not just fail; it forecloses avenues.

The fourth mistake is consenting to simplified extradition. In many jurisdictions, a person may waive the extradition procedure and consent to surrender. This is sometimes presented as the easier route. It eliminates the most important defences available to you. Unless you are advised by someone with specialist extradition knowledge that consent is genuinely in your interest, treat any such suggestion with caution.

Step 5: Understand the realistic prospects honestly

Extradition hearings are not won on the strength of the individual's indignation or the injustice of the underlying case. They are decided on legal grounds that the requested state's law recognises. Before any hearing, you should have an honest view of: which grounds are available on the facts; which are strong and which are thin; what the relevant jurisdiction's track record is on each ground; and what happens if the hearing is lost.

No honest adviser guarantees an outcome in extradition proceedings. Anyone who does should be treated with scepticism. What specialist advice gives you is a clear picture of the real grounds, the sequencing that maximises them, and the parallel CCF track where it is relevant. Those things can change the outcome. They do not guarantee it.

If the extradition request is built on a prosecution that is politically motivated, or where the underlying INTERPOL data is non-compliant, the prospects for both the CCF and the court are materially better than in a straightforward mutual legal assistance case. But "materially better" is not a promise of success.

The steps above are the general picture. Your situation turns on the specific file, the requesting state, the jurisdiction of detention, and the timing. That is exactly what a proper assessment looks at.

Common myths about extradition and the CCF

Several beliefs about extradition regularly reach us through enquiries. Each of them, left unchallenged, leads to poor decisions.

Myth: a Red Notice means I must be surrendered. It does not. A Red Notice is a request to locate and provisionally detain. Whether surrender actually occurs is decided entirely by the requested state under its own extradition law. Countries refuse extradition requests regularly, on grounds including human-rights risk, political character, and procedural failure.

Myth: if the CCF does not act quickly, extradition will happen first. The two proceedings are separate. The CCF's nine-month deletion timeline and the extradition hearing timetable in the requested state may run concurrently. In some matters, the court is slower than the CCF. In others, the reverse. The two tracks must be managed in parallel, not treated as alternatives.

Myth: a lawyer in the requesting state can fix this. They generally cannot. The proceedings that matter – the CCF review and the extradition hearing – take place outside the requesting state. Counsel in the requesting state may be able to address the underlying prosecution, which is sometimes the right long-term objective. But it is a separate question from resisting the extradition and the notice in the meantime.

Myth: asylum or refugee status automatically prevents extradition. Refugee status and the principle of non-refoulement are powerful defences, but they are not automatic bars. Their force depends on the law of the requested state, the nature of the threat, and the specific terms of any asylum grant. They must be raised and evidenced in the extradition proceedings by someone who knows how they interact with the applicable extradition law.

If an earlier CCF submission or court defence produced a refusal, a careful second reading may identify what was missed and whether there are sufficient new elements for a review. Remembering that there is no appeal, that review must be constructed with care. To explore whether there are grounds, write to us at info@northlarkfirm.com.

Frequently asked questions

What should I avoid saying or signing?

Do not make any statement to police, border officers or court officials without specialist extradition counsel present. At the point of provisional arrest, you may be offered documents to sign – including consent to simplified extradition or a waiver of rights. Signing these can eliminate your most important defences. Exercise the right to silence until advised. In particular, do not volunteer information about travel plans, assets, or the underlying dispute.

Who should I contact before I travel again?

Before travelling to any country other than your current state of residence, file a CCF access request if you have not done so already. An access request must be answered within four months, and the response tells you whether an active Red Notice or diffusion exists and which bureau filed it. After receiving that information, take legal advice on the risk profile of each planned destination. Some countries act on INTERPOL alerts automatically; others give greater discretion to their border authorities. That distinction matters before you book a ticket.

Can this be resolved without a court hearing?

Sometimes, yes. If the extradition request is withdrawn by the requesting state – perhaps because the underlying prosecution collapses or a CCF deletion removes the notice that prompted the provisional arrest – the hearing may not proceed. A successful CCF deletion can materially reduce the basis for extradition, even if the court proceedings formally remain open. However, assuming that a CCF outcome will make the court hearing unnecessary is not prudent. Both tracks should be maintained until the extradition request is formally withdrawn.
