Extradition from Switzerland to China: defending against a Red Notice

A Chinese Red Notice reaches Switzerland, and suddenly the ordinary protections of Swiss law meet the formal machinery of INTERPOL. The question most people ask first is the wrong one: "Will I be arrested?" The better question is: "On what grounds can this request be resisted, and how much time do I have?"

Extradition from Switzerland to China is, in practice, extraordinarily rare. Switzerland has no extradition treaty with China, and Swiss courts apply exacting human-rights standards before agreeing to any surrender. A Red Notice in this corridor is a request to locate and provisionally detain – it is not an arrest warrant and not a judicial decision. The realistic question is not whether extradition is legally possible in principle, but whether the grounds to resist it are well-assembled and presented at the right moment.

This analysis covers the treaty position, the human-rights and dual-criminality defences available under Swiss extradition law, the interaction with INTERPOL's own rules, and an honest account of what the process looks like from inside a live case.

What is the treaty position between Switzerland and China?

There is no bilateral extradition treaty between Switzerland and China. That single fact is the foundation of the defence in this corridor. Without a treaty, Switzerland cannot be compelled to extradite, and any request must work through the ordinary domestic extradition law of the requested state – Swiss law in this case.

Swiss extradition law allows the Federal Office of Justice to consider ad hoc requests from states with which Switzerland has no treaty. However, the absence of a treaty removes reciprocity as a lever. Swiss authorities apply their domestic extradition statute and international human-rights obligations with full force. In our experience before proceedings in this corridor, the absence of a treaty does not mean a request is refused automatically. It means every element of the defence is assessed on its own terms by Swiss authorities, without the shortcuts that a treaty sometimes provides to the requesting state.

As of mid-2025, there is no credible public indication that Switzerland and China are negotiating a bilateral extradition treaty. That position should be kept under review.

How does a Red Notice function in this corridor?

A Red Notice is a request circulated by INTERPOL – at China's National Central Bureau – to locate and provisionally detain a person with a view to extradition. It does not create a legal obligation for Switzerland to arrest. Each Swiss authority – cantonal police, the Federal Office of Justice, a court – decides under Swiss law whether to act on it.

In practice, a Red Notice in this corridor can trigger a provisional arrest at the border or a check at cantonal police level. What it cannot do is compel a court to order detention without reference to Swiss procedural guarantees. The first hearing after a provisional arrest is precisely where the defence must be ready.

A diffusion – an alert circulated directly by the Chinese National Central Bureau, outside the formal notice system – can also trigger checks at the border or with cantonal authorities. Diffusions are less visible than Red Notices but can be challenged before the Commission for the Control of INTERPOL's Files (CCF) on the same grounds as a notice. We regularly see diffusions used where a formal Red Notice has already been refused by the General Secretariat or is under CCF review.

In a matter involving a MENA-origin diffusion (autumn 2024), we identified that the formal notice had been refused and that a diffusion had been substituted without the individual's knowledge. Filing before the CCF on data-accuracy grounds under the RPD's data-quality requirements led to the diffusion being withdrawn. The same pattern arises in China-origin cases.

What human-rights defences apply under Swiss law?

Human-rights grounds are the primary shield in this corridor. Swiss extradition law expressly incorporates the European Convention on Human Rights and Switzerland's obligations under the UN Convention Against Torture. Surrender is refused where there is a real risk that the requesting state will subject the individual to treatment prohibited by those instruments.

In a China-origin extradition request, the following risks are typically examined:

• The risk of torture or inhuman or degrading treatment in detention, including conditions in pre-trial facilities.
• The absence of a fair trial guarantee, including the independence of the judiciary from the party-state in politically sensitive matters.
• The use of residential surveillance at a designated location – a form of incommunicado detention outside formal criminal procedure.
• The targeting of ethnic minorities, notably in cases that engage Uyghur, Tibetan or Mongolian identity – grounds that also engage Article 3 of INTERPOL's own Constitution, which bars notices of a racial character.

Switzerland's Federal Criminal Court has, in this and analogous corridors, refused surrender on human-rights grounds. We do not cite specific decisions, but the consistent thread is the same: country-conditions evidence, properly assembled, carries the argument. A general assertion of risk does not. The file must show, with country reporting and expert analysis, that the individual's specific profile creates an individualised risk.

Article 2 of INTERPOL's Constitution requires that INTERPOL's activities respect human rights in the spirit of the Universal Declaration of Human Rights. That obligation runs alongside – and can reinforce – the Swiss constitutional and treaty-based analysis. Where a notice has been issued and its human-rights compliance is in question, a CCF challenge and a Swiss court defence can run in parallel.

Does dual criminality present a real defence here?

Dual criminality – the requirement that the conduct underlying the request constitutes an offence under both Chinese and Swiss law – must be satisfied before Swiss authorities will proceed. This is not a formal procedural technicality. It is a substantive filter, and in China-origin cases it regularly reveals significant gaps.

Several categories of conduct routinely prosecuted under Chinese criminal law do not map cleanly onto Swiss criminal law:

• "Picking quarrels and provoking trouble" – a broad catch-all charge used against activists, journalists and business competitors – has no Swiss equivalent.
• Economic crimes framed around conduct that, under Swiss law, constitutes ordinary commercial dispute resolution or regulatory non-compliance rather than criminal fraud.
• Offences with an explicitly political character – which also engage Article 3 of INTERPOL's Constitution – where Swiss law does not criminalise the underlying behaviour at all.

In an extradition matter in Central Europe (spring 2025), a client facing a China-origin request saw the proceedings terminated at the dual-criminality stage when analysis showed that the conduct alleged did not constitute a criminal offence under the law of the requested state. The same analysis applies in Swiss proceedings, and it should be done before provisional arrest if possible – because the quality of the initial submission shapes the detention decision.

Visas and residence permits are sometimes refused without explanation precisely because a Red Notice or a diffusion is circulating. The dual-criminality analysis should run alongside any immigration remedy. Establishing that the underlying conduct is not criminal under Swiss law is relevant both in extradition court and before the competent immigration authority.

What is the honest position on provisional arrest and bail?

Provisional arrest on the basis of a Red Notice or an ad hoc request is legally possible in Switzerland. Whether it occurs in practice depends on a number of factors: how the notice is presented to cantonal authorities, whether the individual has an established residence in Switzerland, and whether the defence is in place before the arrest takes place.

The window after provisional arrest is short. Swiss procedural law sets statutory timelines for the first hearing. The defence must be ready to contest the legality of the arrest, to argue against continued detention, and to put human-rights and dual-criminality submissions before the court – all within that first window.

We do not promise a specific outcome at the bail or detention review stage. What we can say, from our practice in this and comparable corridors, is that the quality of the initial submission – the country evidence, the legal analysis of dual criminality, the INTERPOL data challenge filed in parallel – directly affects the detention decision. A weak first file makes every subsequent step harder. This is the honest position, and we hold to it.

The steps that matter in the first hours are: retaining counsel immediately, establishing whether a notice or a diffusion is the operative instrument, and filing an emergency CCF application where the data underpinning the notice is demonstrably defective or non-compliant. None of those steps can be taken retrospectively.

The steps that matter before any travel are: an access request to the CCF to learn whether INTERPOL holds data about you, and an honest assessment of the strength of any pre-emptive challenge. For a full account of how Swiss extradition proceedings work, stage by stage, see our Switzerland extradition overview.

If you have already been through a first CCF request that produced a refusal, a second review requires new elements. There is no appeal against a CCF decision, so the new file must be built on grounds that were either not raised or not evidenced fully the first time. That is a precise exercise, not a repetition of the original submission.

How does the CCF challenge interact with Swiss extradition proceedings?

The CCF process and Swiss extradition proceedings are separate mechanisms. They run on different timelines, before different bodies, and produce different remedies. Understanding the interaction – and the sequencing – is essential.

A deletion request filed before the CCF, if admitted, is to be decided within nine months of admissibility. An access request – to confirm whether data is held – is to be answered within four months. Swiss extradition proceedings do not pause for the CCF. Both must be managed in parallel, with consistent legal positions across both.

Where a notice is deleted by the CCF, that deletion removes the INTERPOL instrument from the equation. Swiss authorities may still be able to act on an ad hoc request from China, but the removal of the notice weakens the requesting state's position materially. In our practice, a CCF deletion issued during pending extradition proceedings has led to the withdrawal of the extradition request in more than one matter.

The grounds before the CCF are those in INTERPOL's Constitution and the RPD's data-accuracy and processing requirements. The grounds before a Swiss court are those in Swiss extradition law and Switzerland's human-rights obligations. The analysis for both must be done from the same factual base, but the legal arguments are distinct. For an account of how Chinese Red Notices are structured and challenged at the CCF level, see our China Red Notice analysis.

A common misconception: does a Red Notice mean the case is lost?

The most persistent myth in this corridor is that a Red Notice from China is effectively unanswerable – that INTERPOL defers to its member states, that the CCF never deletes a Chinese notice, and that extradition is simply a matter of time. None of that is accurate.

A Red Notice is a request. It is not a conviction, not an arrest warrant, and not a judicial decision. No country is obliged to arrest on the basis of a Red Notice alone. Switzerland, which operates with full rule-of-law protections and an independent judiciary, is not going to surrender an individual to a state with which it has no extradition treaty without a thorough human-rights and dual-criminality analysis.

The CCF does examine Chinese notices. Where the grounds under INTERPOL's Constitution – particularly Article 3, which bars notices of a political, military, religious or racial character, and Article 2, which requires respect for human rights – are properly evidenced, the CCF acts on them. We work in the language of the file and the requesting state, which means that the political and legal context of the underlying Chinese proceedings can be analysed accurately and presented persuasively to the Commission.

The honest limit is this: the CCF is not a court of appeal over Chinese criminal proceedings. It cannot acquit, and it cannot order China to drop the prosecution. What it can do is examine whether the notice complies with INTERPOL's own rules. Where it does not, deletion is the outcome. For a full analysis of how Article 2 human-rights grounds are argued before the CCF, see our dedicated Article 2 page.

Frequently asked questions

Can I be released or bailed during proceedings?

Provisional detention following arrest on the basis of a Red Notice is reviewed by Swiss courts under Swiss procedural law. Release or bail is not automatic, but it can be argued – particularly where dual criminality is in doubt, where human-rights grounds are strong, or where the notice is under active CCF review. The outcome depends on the quality of the submission at the first hearing, which is why representation must be in place before arrest wherever possible.

Does dual criminality apply to my case?

Swiss extradition law requires that the conduct underlying the request constitutes a criminal offence under both Chinese and Swiss law. In China-origin cases, this test regularly fails: broad Chinese charges such as "picking quarrels and provoking trouble," or economic offences that reduce to commercial disputes under Swiss law, often do not satisfy it. A detailed dual-criminality analysis of the specific Chinese charge is one of the first steps we take in any Switzerland-China matter.

What is the rule of specialty and does it help me?

The rule of specialty holds that, if a person is extradited for a specified offence, the requesting state may not prosecute or punish them for a different offence committed before surrender. In the absence of an extradition treaty between Switzerland and China, specialty would need to be guaranteed by diplomatic assurance. Swiss courts scrutinise such assurances with care, and where they are not credible, specialty provides an independent ground to resist surrender.
