Spain handles extradition through the Audiencia Nacional in Madrid. Provisional arrest at the border is followed by a hearing before the central criminal court. Bail is possible in some cases. Defence focuses on dual criminality, human-rights compliance, and the political-offence exception.
Spain's Audiencia Nacional is the central court that handles extradition cases, international arrests, and cross-border criminal matters. It is based in Madrid and has jurisdiction over all extradition requests, whether from EU member states (European Arrest Warrants) or non-EU countries. The court's procedures are well-established, and its jurisprudence on extradition — particularly on human-rights grounds — is significant.
The Spanish Extradition Process
- Provisional arrest: A person detained at a Spanish border on an Interpol Red Notice is transferred to the Audiencia Nacional. The court holds an initial hearing to confirm the detention.
- Extradition hearing: The court assesses dual criminality, the validity of the request, and any bars to extradition. Defence arguments focus on political motivation, human-rights violations, and procedural defects.
- Bail: Spanish law permits bail during extradition proceedings. The court assesses flight risk and the seriousness of the underlying charge.
- Appeal: The Audiencia Nacional's decision can be appealed to the Spanish Supreme Court (Tribunal Supremo).
Critical Warning for Travelers
Spain is a Schengen state and queries SIS II at its borders. A SIS II alert or an Interpol diffusion will trigger detention at any Spanish airport, including Madrid, Barcelona, and Malaga. Spain is a popular destination and transit hub — do not assume that a holiday destination is lower risk.
Spanish Jurisprudence on Extradition
The Audiencia Nacional has developed significant jurisprudence on extradition, particularly on human-rights grounds. Spanish courts have refused extradition to several states where the requesting country's prison conditions violate Article 3 of the ECHR or where the prosecution lacks judicial independence. The court applies a rigorous human-rights filter, supported by country reports from the Council of Europe's Committee for the Prevention of Torture and the ECHR's own jurisprudence.
Spain has also been a leader in refusing extradition for political offences. The political-offence exception, recognised in Spanish extradition law, prevents extradition where the underlying prosecution is politically motivated. The court assesses the political context, selective nature, and involvement of political figures, applying criteria similar to those used by the CCF under Article 3 of the Interpol Constitution.
Dual criminality is strictly applied. The conduct underlying the extradition request must be criminal under Spanish law, and the court assesses whether the specific facts alleged meet the elements of the Spanish offence. Where the conduct is a civil matter under Spanish law (for example, a commercial dispute recharacterised as fraud in the requesting state), the court may refuse extradition on dual-criminality grounds.
Defence Strategy in Spanish Extradition
Defence in Spanish extradition requires Spanish counsel familiar with the Audiencia Nacional's procedures, working in coordination with Swiss counsel on the parallel CCF deletion petition. The two tracks are complementary — the Spanish defence addresses the immediate detention and extradition hearing, while the CCF petition addresses the underlying Interpol notice. If the CCF deletes the notice, the Spanish proceedings become moot.
Bail is possible in Spanish extradition proceedings, subject to the court's assessment of flight risk. Factors favouring bail include community ties in Spain, a fixed address, the absence of a prior criminal record, and a substantial surety. The court's decision can be appealed to the Tribunal Supremo. In one case, a client detained at Madrid Barajas on a diffusion was granted bail within two weeks, because counsel demonstrated strong community ties and the underlying charge was a commercial dispute recharacterised as fraud.
Spanish Bail in Extradition Cases
Spanish law permits bail during extradition proceedings, subject to the Audiencia Nacional's assessment of flight risk. The court considers factors including community ties in Spain, family dependents, employment, the seriousness of the underlying charge, and the existence of multiple passports. Bail conditions typically include surrender of passport, regular reporting, and a substantial surety. The surety is returned if the person complies with bail conditions.
Spanish bail is more accessible than in some other European jurisdictions, particularly for cases involving commercial disputes recharacterised as fraud. The court recognises that a person with strong community ties and a fixed address is less likely to flee, and the surety provides a financial incentive to appear. In one case, a client detained at Madrid Barajas on a diffusion was granted bail within two weeks, because counsel demonstrated strong community ties, a stable employment history, and the commercial nature of the underlying dispute.
