Extradition from Switzerland to Iran: defending against a Red Notice

Switzerland is one of the safest places in Europe to live outside the reach of an unfounded extradition request. It is not immune to one. When an Iranian Red Notice is in the system, Swiss authorities are required to assess it – and in some cases to act on it. The question is not whether Switzerland will automatically comply, but whether the defence is built before the process reaches a stage that is difficult to reverse.

Extradition from Switzerland to Iran faces a high legal bar. Switzerland has no bilateral extradition treaty with Iran, and any request must clear the requirements of Swiss extradition law, the European Convention on Extradition, and the human-rights obligations that Swiss courts apply with real force. A Red Notice in this corridor is a serious operational problem, but it is not a judicial sentence. The grounds to resist surrender are substantial, and timing is the first thing that matters.

This analysis covers the treaty position, the human-rights and dual-criminality defences, how a Red Notice interacts with formal extradition, and what a realistic defence looks like from the moment a person is located in Switzerland.

What is the treaty basis for extradition between Switzerland and Iran?

Switzerland has no bilateral extradition treaty with Iran, and that absence matters from the first day of any proceeding. Without a treaty, Iran cannot make a request through the normal reciprocal channel that most bilateral corridors use. Any Iranian request received by Switzerland must be handled under domestic Swiss extradition law alone. That law requires strict compliance with a set of conditions that are independently assessed by Swiss courts – and those courts are not deferential to the requesting state's characterisation of the offence.

In our extradition practice, the absence of a treaty is not a shield by itself. A state may still issue a formal request through diplomatic channels, and Switzerland may still provisionally detain a person where a Red Notice is flagged. What the absence of a treaty does is remove the presumption of good faith that some bilateral agreements generate. Every element of the Iranian request must be proved to Swiss standards, not assumed. That shifts the burden in a meaningful way.

Switzerland applies the European Convention on Extradition as a framework for many of its extradition relations, but Iran is not a party to that Convention. The practical consequence is that Swiss courts fall back on domestic statutory provisions and on Switzerland's own constitutional and human-rights obligations. Those obligations are among the most protective in Europe.

How does a Red Notice operate in this corridor?

A Red Notice issued at Iran's request is a request to locate and provisionally detain a person with a view to extradition. It is not an arrest warrant. It is not a judicial decision. It does not establish guilt, and it does not oblige any country – including Switzerland – to arrest or surrender. Switzerland decides under its own law whether to act on a Red Notice, and the Swiss legal system provides several points at which a challenge can be mounted.

As of mid-2025, reliable reporting indicates that Iranian requests through INTERPOL remain active across multiple jurisdictions. The pattern we see in practice is that an Iranian Red Notice is often the first formal signal a person receives – sometimes at a border crossing, sometimes when a bank flags an account or a visa is refused without explanation. That second scenario is common and disorienting. Residence permits are declined. Contracts fall through. The underlying Red Notice may not yet have resulted in any formal approach to Swiss authorities, but its effects are already concrete.

The correct response is not to wait for the formal extradition request. Once a Red Notice is confirmed in the system, two parallel tracks open: a challenge before the Commission for the Control of INTERPOL's Files (CCF), and a pre-emptive assessment of what Swiss extradition law would require if a formal request arrives. Those tracks inform each other. A successful CCF challenge removes the notice from circulation and can neutralise the extradition trigger altogether. A CCF deletion request is, under the applicable rules, to be decided within nine months of being found admissible – which means the timeline is manageable, if the file is strong.

In a recent matter involving a MENA-origin notice (summer 2025), we submitted a CCF challenge on data-accuracy grounds before a formal extradition request was lodged. The notice was removed. No extradition proceeding followed. The sequencing was deliberate.

What human-rights defences apply in Swiss extradition proceedings?

Human-rights arguments are the strongest and most frequently used defences in this corridor. Swiss courts apply them with genuine rigour, and they can result in refusal even where the formal conditions for extradition would otherwise be met. The relevant standards derive from Switzerland's own constitutional guarantees and from the European Convention on Human Rights, to which Switzerland is a party.

The most consistently available grounds include the following.

• Risk of torture or inhuman treatment. Swiss courts will refuse surrender where there are substantial grounds to believe the person would face treatment prohibited by absolute human-rights norms in Iran. Country-conditions evidence – from international human-rights bodies, credible NGO documentation, and Swiss Federal Court precedent on the receiving state – is central to this argument. The evidential burden is demanding, but the Iranian record is extensive and well-documented.
• Fair trial. Where the criminal proceedings in Iran do not meet the minimum guarantees that Swiss law requires of a foreign procedure, surrender can be refused. The relevant question is whether the person would have access to an independent tribunal, adequate defence, and a process that is not predetermined. In our experience before extradition courts, that argument carries the most weight when supported by specific evidence about the Iranian case, not generic assertions about the system.
• Political character of the prosecution. Article 3 of INTERPOL's Constitution bars processing linked to offences of a political, military, religious or racial character. The same principle applies in Swiss extradition law: a request that is politically motivated, or that targets a person for their political views or religious identity, must be refused. This ground overlaps with the INTERPOL challenge and should be argued in both forums, consistently.
• Non-refoulement. Where the person holds refugee status or has a pending asylum claim, non-refoulement operates as a hard bar to surrender. Swiss asylum authorities and the extradition court must coordinate; in practice, an asylum determination can stay extradition proceedings for the duration of the asylum process.

Article 2 of INTERPOL's Constitution requires that INTERPOL's activity respect human rights, in the spirit of the Universal Declaration. That standard, applied by the CCF, mirrors what Swiss courts apply on the extradition side. A coherent defence addresses both bodies with a consistent factual and legal record.

Does dual criminality create a defence here?

Dual criminality – the requirement that the conduct alleged must constitute a criminal offence under the law of both the requesting and the requested state – is a mandatory condition in Swiss extradition law. Switzerland will not surrender a person for conduct that is not criminal under Swiss law, regardless of how it is characterised in the Iranian request.

In this corridor, dual criminality is often underestimated as a defence ground. Iranian charges sometimes rely on provisions of Iranian law that have no Swiss equivalent – public-order offences, religious offences, or economic offences framed in ways that reflect a regulatory environment with no counterpart in Swiss law. The task is to analyse the actual conduct alleged, strip away the Iranian legal label, and ask whether the underlying acts would be criminal in Switzerland. In a number of corridor matters, that analysis has produced a negative answer.

The analysis must go to the underlying facts, not the charge label. A charge of "economic disruption" in Iran may or may not correspond to fraud under Swiss law. A charge of "apostasy" or a politically-coded public-order offence is unlikely to. Swiss courts do not simply accept the requesting state's categorisation; they examine the substance.

Where dual criminality fails, the Swiss extradition court has no jurisdiction to order surrender. That is a clean result, and it is one worth building the file towards from the outset.

What happens at the first hearing, and how quickly must the defence act?

Speed is not optional in this corridor. If Swiss authorities receive a formal extradition request accompanied by a Red Notice, the first hearing can follow within days. At that hearing, the court considers whether to maintain provisional detention and sets the procedural timetable. The submissions made at that stage – on human rights, dual criminality, and the political character of the prosecution – shape the entire proceeding. A poorly prepared first appearance is genuinely difficult to recover from.

In our extradition practice, the documents we need at the first stage are: the full text of the Iranian request (or the Red Notice content where no formal request has yet arrived), any prior correspondence with Iranian authorities, evidence of the political or personal background to the prosecution, documentation of country conditions in Iran, and – where relevant – evidence of asylum or refugee status. Many of those documents can be assembled before any hearing, if the assessment is done early enough.

Provisional arrest on the basis of a Red Notice can precede a formal extradition request. Where a person is detained at a Swiss border or in-country, the clock on procedural steps begins immediately. Swiss law provides a statutory window within which the requesting state must lodge its formal extradition documents. If that window is not met, release follows. Knowing that window – and monitoring it – is part of the defence.

The steps above are the general picture. Your situation turns on the specific Iranian file, the stage of the Swiss proceeding, and the grounds available on your facts – which is exactly what a confidential assessment is designed to clarify.

What is the realistic outcome in this corridor?

No honest lawyer guarantees a result in any extradition proceeding, and we do not. What can be said about this corridor is that the combination of no bilateral treaty, strong Swiss human-rights standards, and the evidentiary record on Iran produces a set of grounds that are substantive rather than technical. This is not a corridor where the defence is searching for loopholes; it is one where the grounds are real and well-established.

The realistic prospects depend on three variables: the quality and specificity of the human-rights evidence assembled; whether dual criminality can be defeated on the facts; and the political or commercial background to the Iranian prosecution. Where all three are favourable, the case for refusal is strong. Where one is weak, the defence must compensate with the others.

There is a related point about the INTERPOL dimension. Deleting the notice at source, through a successful CCF challenge, is distinct from a result in the Swiss national court. A Swiss extradition refusal does not automatically remove the Red Notice from INTERPOL's systems; it must be challenged separately. Conversely, a CCF deletion does not bind the Swiss court if a formal request has already arrived. In our practice, we handle both in parallel, because the durable outcome requires both.

In a matter involving a CIS-origin notice with an Iranian-adjacent fact pattern (winter 2024), the extradition request was refused by the national court on human-rights grounds; the CCF challenge was filed simultaneously and the notice removed within the applicable review period. That dual approach is now standard in our corridor work.

Common errors that weaken a defence in this corridor

The mistakes we see most often are structural rather than tactical. They compound over time, and some are difficult to correct once made.

• Waiting for the formal extradition request before engaging. The Red Notice itself is actionable. Challenging it at the CCF level before a formal request arrives can remove the operational trigger. Waiting converts a CCF matter into a live extradition case.
• Filing a weak CCF request as a first step. There is no appeal against a CCF decision. A first file that fails to make the legal argument properly leaves the person in the same position with a harder path to a review. The quality of the initial submission is not a matter of preference; it is determinative.
• Generic human-rights assertions without country-specific evidence. Swiss courts and the CCF both expect evidence, not assertions. A submission that says "Iran has a poor human-rights record" without specific documentation of what would happen to this person in this case is insufficient. The file must be granular.
• Ignoring the asylum track. Where refugee status is available or an asylum claim is arguable, that route should be assessed in parallel with the extradition defence. The two proceedings interact, and the asylum determination can protect the person while the extradition matter is resolved.
• Inconsistent positions across forums. If the CCF file characterises the prosecution one way and the Swiss extradition submission characterises it differently, both submissions are damaged. Coherence across every forum is a discipline, not a detail.

If a first CCF request or an earlier defence produced a refusal, a second reading can identify what was missed and whether there are new elements – remembering there is no appeal, so a review must be built with precision.

Frequently asked questions

What happens at a first extradition hearing?

At the first hearing, the Swiss court decides whether to maintain provisional detention and sets the procedural timetable for the extradition proceeding. Submissions on human rights, dual criminality and the character of the prosecution are made at this stage. The submissions lodged here shape the entire case. A person who arrives at that hearing without a prepared legal file is at a significant disadvantage, and recovering that ground later is genuinely difficult.

Can extradition be refused on human-rights grounds?

Yes. Swiss courts apply human-rights standards with real force. Where there are substantial grounds to believe a person would face torture, inhuman treatment or an unfair trial in Iran, surrender must be refused. This is not a discretionary consideration in Swiss law – it is a mandatory bar. Country-conditions evidence specific to the person's situation, not generic assertions about Iran, is what the court examines. Where that evidence is well-assembled, the ground is strong.

How does the Red Notice affect the request?

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 does not oblige Switzerland to surrender anyone. It can trigger provisional detention while a formal extradition request is prepared, and it causes immediate practical consequences – travel problems, banking difficulties, visa refusals. Challenging the Red Notice before the CCF, in parallel with the national extradition defence, is the approach most likely to produce a durable result in this corridor.
