Can You Be Extradited Immediately Upon Airport Arrest?

No. Summary deportation or immediate extradition is illegal under most legal systems. After an airport arrest, provisional detention follows while the requesting state submits formal extradition documents. Bail may be possible depending on the jurisdiction. The process takes weeks to months, and counsel can challenge detention length, the validity of the alert, and the extradition request itself.

The fear of "immediate extradition" — being put on a plane to the requesting country within hours of an airport arrest — is common but unfounded in most jurisdictions. International law and national extradition procedures require a formal process: provisional arrest, notification of the requesting state, submission of formal extradition documents, and a judicial hearing. This process takes time, and during that time, the detained person has the right to counsel, to challenge detention, and to apply for bail.

What Happens After an Airport Arrest

After a Red Notice or diffusion match triggers detention at an airport, the border authority contacts the National Central Bureau, which confirms with the requesting country whether the alert is active and whether provisional arrest should proceed. If the requesting country confirms, a provisional arrest warrant is issued by the transit country, and the passenger is transferred from the border detention facility to a standard detention facility.

The requesting country then has a limited period — typically 40 to 60 days under the European Convention on Extradition, though the exact period varies by jurisdiction and treaty — to submit formal extradition documents. These documents include the underlying arrest warrant, the charging document, a summary of the facts, and evidence sufficient to establish dual criminality (the requirement that the conduct is criminal in both the requesting and requested states).

Once the formal documents are submitted, an extradition hearing is scheduled before the competent court. The hearing assesses dual criminality, the validity of the request, and any bars to extradition (political motivation, human-rights violations, statute of limitations). If the court approves extradition, the decision can be appealed to higher courts. The entire process can take months or, in complex cases, years.

The Extradition Timeline

1. Provisional arrest (Day 1): The passenger is detained at the border, the alert is confirmed, and a provisional arrest warrant is issued by the transit country.
2. Formal extradition documents (40-60 days): The requesting country submits the formal extradition request with supporting documents. The detained person can apply for bail during this period.
3. 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.
4. Appeal (if extradition approved): The decision can be appealed to higher courts. The appeal process can take months, during which the person may remain in detention or on bail.

Bail and Release Pending Extradition

Bail is possible in many jurisdictions during the extradition process, particularly where the flight-risk argument is weak. Factors that favour bail include strong community ties in the transit country, a fixed address, the absence of a prior criminal record, and the submission of a substantial surety. Factors that weigh against bail include the seriousness of the underlying charge, the existence of multiple passports, and any evidence of attempted flight.

In one case, a client detained at Schiphol on a diffusion was granted bail within ten days, because counsel demonstrated strong community ties in the Netherlands, a fixed address, and the fact that the underlying charge was a commercial dispute that had been recharacterised as fraud. The client was released pending the extradition hearing, which ultimately rejected the request on Article 3 grounds (political motivation). Simultaneously, a CCF deletion petition was filed, and the diffusion was deleted.

The Provisional Arrest to Extradition Pipeline

The period between provisional arrest and the extradition hearing is the most critical phase for the detained person. During this period, the person is in detention, the requesting state is preparing its formal extradition documents, and counsel is mounting the defence. The outcome of this phase determines whether the person is released on bail, remains in detention, or — in the worst case — is extradited. The speed and quality of the legal response during this period is decisive.

The two-track strategy — local defence in the transit country and CCF deletion in Lyon — must be initiated simultaneously. Local counsel challenges the detention, applies for bail, and prepares the extradition defence. Swiss counsel files the CCF deletion petition, which addresses the root cause. If the CCF deletes the notice before the extradition hearing, the local proceedings become moot. The two tracks reinforce each other, and the parallel approach maximises the probability of a favourable outcome.

What to Do in Practice: Secure Your Clearance

Immediate extradition is not legal, but detention can last for months if the process is not actively managed. The best defence is to avoid the arrest altogether by clearing any alert before travel. If an arrest occurs, the priority is to secure counsel immediately, apply for bail, and file a CCF deletion petition in parallel. The two tracks — extradition defence in the transit country and CCF deletion in Lyon — work together to secure release.
