Yes. The US-Switzerland extradition treaty is active and frequently used, particularly in financial-crime cases. The FOJ processes the request under IMAC, and the Federal Court reviews compliance with dual criminality and human-rights standards. Defence focuses on treaty exceptions, proportionality, and the political-offence exception.
The US-Switzerland extradition relationship is one of the most active in the world, particularly in financial-crime cases (tax fraud, securities fraud, money laundering, sanctions evasion). The bilateral treaty dates to 1990 and is supplemented by the IMAC. Switzerland has historically been willing to extradite to the US where the legal criteria are met, but the Federal Court applies strict review of dual criminality, proportionality, and human-rights compliance.
Critical Warning for Travelers
US-Switzerland extradition is active and frequently used in financial-crime cases. If you face a US extradition request or suspect a US-issued Interpol alert, do not travel to or through Switzerland without first clearing the alert through a CCF deletion petition. Swiss defence avenues are strong, but the best course is prevention.
Key Defence Arguments in US-Switzerland Extradition
- Dual criminality: The conduct must be criminal in both the US and Switzerland. Some US financial offences (particularly tax-related) do not have exact Swiss equivalents, and the dual-criminality analysis can be a strong defence.
- Political offence exception: The treaty contains a political-offence exception. If the prosecution is politically motivated, extradition can be refused.
- Human-rights compliance: US prison conditions, particularly in federal facilities, can be challenged under Article 3 of the ECHR. The Federal Court has refused extradition in cases where the conditions would violate human rights.
- Statute of limitations: If the Swiss statute of limitations for the equivalent offence has expired, extradition can be refused.
The US-Switzerland Treaty Framework
The US-Switzerland extradition treaty, signed in 1990 and supplemented by the 2006 protocol, establishes the legal framework for extradition between the two countries. The treaty covers offences punishable by more than one year's imprisonment in both jurisdictions (dual criminality). The IMAC (Bundesgesetz über internationale Rechtshilfe in Strafsachen) implements the treaty into Swiss domestic law and governs the procedural aspects of extradition.
The treaty includes several exceptions. The political-offence exception bars extradition where the underlying prosecution is political. The military-offence exception bars extradition for military offences. The fiscal-offence exception has historically been significant — Switzerland did not extradite for tax offences that were not criminal under Swiss law, though this exception has been narrowed in recent years as Switzerland has tightened its tax-fraud legislation. Dual criminality is strictly applied — the conduct must be criminal in both jurisdictions, not merely the label of the offence.
Financial-Crime Extradition: The Active Area
US-Switzerland extradition is most active in financial-crime cases — tax fraud, securities fraud, money laundering, sanctions evasion, and FCPA violations. Switzerland's role as a global financial centre, combined with its banking secrecy history, has made it a focus of US law-enforcement attention. Several high-profile cases have involved US requests for the extradition of foreign nationals detained in Switzerland on financial-crime charges.
Defence in financial-crime extradition cases often focuses on dual criminality — arguing that the specific conduct alleged does not meet the elements of the Swiss equivalent offence. This is particularly effective where the US offence is defined broadly (for example, securities fraud under US law) but the Swiss equivalent is narrower. Defence may also cite the statute of limitations — if the Swiss limitation period for the equivalent offence has expired, extradition can be refused.
In one case, a client faced US extradition from Switzerland on securities-fraud charges. Counsel argued that the specific conduct alleged — certain trading activities — did not meet the elements of Swiss securities-fraud offences, which were narrower than the US definition. The Federal Criminal Court agreed and refused extradition. The ruling was upheld on appeal. A parallel CCF deletion petition was filed, and the underlying Red Notice was deleted on the grounds that the conduct was not criminal in Switzerland and therefore did not meet the dual-criminality requirement for Interpol processing.
The Fiscal Offence Exception
The fiscal offence exception has historically been a significant feature of US-Switzerland extradition. Swiss law distinguished between tax fraud (a criminal offence) and tax evasion (an administrative offence), and Switzerland did not extradite for conduct that was merely an administrative offence under Swiss law. This exception narrowed over time as Switzerland tightened its tax-fraud legislation and entered into international agreements on tax information exchange, but it remains relevant in certain cases.
The exception is particularly relevant for cases involving US tax charges. If the conduct underlying the US extradition request is classified as tax evasion rather than tax fraud under Swiss law, the dual-criminality requirement may not be met, and extradition can be refused. The analysis is fact-specific — counsel assesses the specific conduct alleged in the US request and compares it with the elements of the Swiss offence. Where the conduct does not meet the Swiss criminal threshold, the dual-criminality defence is strong, and extradition can be refused.
What to Do in Practice: Secure Your Clearance
US-Switzerland extradition is active and frequently used, particularly in financial-crime cases. Defence focuses on dual criminality, the political-offence exception, and human-rights compliance. If you face a US extradition request from Switzerland, engage Swiss counsel immediately and file a parallel CCF deletion petition if the underlying notice is non-compliant.
