Provisional Arrest Before a Formal Request

A formal extradition request is a substantial document. It has to be translated, authenticated, transmitted through diplomatic channels and reviewed before a complaint can be filed, and assembling it takes weeks or months. Treaties therefore allow the requesting state to ask that the person be arrested first, in urgent cases, with the papers to follow. That arrest is provisional, and the word describes both its basis and its fragility.

What provisional arrest is

The mechanism exists because the alternative is to lose the person. A state that learns a wanted individual is about to board a flight cannot wait for a certified package to cross an ocean. The treaty allows it to transmit an urgent request describing the offense, the warrant behind it, the identifying information and an undertaking to submit the formal request, and to ask that the person be held.

What that produces in the United States is an ordinary federal proceeding. A prosecutor files a complaint under oath charging that a person found within the jurisdiction has committed an offense covered by an extradition treaty with the requesting country. A judge or magistrate judge issues a warrant. The person is arrested and brought before the court, and the extradition case begins with the provisional arrest rather than with the request.

An international police notice is not the authority for any of this. Notices circulated among member agencies summarize a foreign warrant and alert police that a person is sought. They have no domestic legal effect, they do not authorize an arrest, and a person taken into custody on a notice alone has been arrested without a basis. In practice a notice prompts the diplomatic contact that leads to the complaint, and the complaint is what the arrest rests on.

The showing at this stage

The judicial officer must be satisfied of the same essentials that will be tested later, on thinner material. That the treaty is in force. That the offense described is covered by it. That there is probable cause to believe the person committed the offense. That the person before the court is the person sought.

The evidence available is usually a summary prepared by the requesting state and transmitted through diplomatic channels, rather than the authenticated depositions and warrants that will accompany the formal request. That thinness is deliberate and it is temporary. The full documentary showing, authenticated by the certificate of the principal diplomatic or consular officer of the United States in the requesting country, is what the extradition hearing will examine.

The deadline and the lapse

The period allowed for the formal request comes from the treaty rather than from any general statute, and it varies. Counting it correctly requires reading the specific instrument, since treaties differ on the length, on whether the period runs from arrest or from notification, and on whether an extension may be sought.

A separate federal statute supplies a comparable rule in a narrow setting. Where provisional arrest and detention occur within the extraterritorial jurisdiction of the United States on a telegraphic request, no person may be held in custody under that section for more than ninety days. That provision applies to a distinct category of case and should not be read as the general rule for treaty extraditions.

When the treaty period expires without the formal request, the person is entitled to release from the provisional custody. What release does not do is end the matter. Treaties commonly state expressly that discharge does not prejudice a subsequent extradition where the request is later submitted in due course, and a fresh warrant may issue on the completed papers. The value of the lapse is the interval of liberty and the opportunity to prepare, which in a document-heavy proceeding is not trivial.

Counsel appointed at a provisional arrest should therefore do two things immediately. Identify the treaty and read its provisional arrest article, since that text supplies the only deadline that matters at this stage and the length is not predictable from other cases. And calendar the expiry date, because nothing in the domestic process will flag it, and the government has no duty to volunteer that the period has run.

Custody in the meantime

Release pending the extradition hearing is difficult. There is no statutory bail scheme for extradition, the ordinary release statutes do not govern, and the Supreme Court has indicated that there is no presumption in favor of bail in this setting, because the United States has undertaken an obligation to produce the person and a release that results in flight is a breach of that undertaking. Courts have developed a special circumstances standard, requiring something beyond the ordinary factors that support release in a domestic case.

What has qualified varies and is fact-bound: serious medical need that the facility cannot meet, an unusual delay attributable to the requesting state, a substantial question about whether the treaty covers the offense at all, or the need to participate in a complex documentary defense that custody makes impracticable. Community ties and a clean record, which would carry a domestic bail motion, are generally insufficient standing alone.

Everything at this stage is preliminary to the proceeding described in international extradition, and the substantive questions raised there, including whether the conduct satisfies dual criminality and what limits the rule of specialty will place on any prosecution that follows, are ordinarily not resolved on a provisional arrest. The domestic analogue, an arrest on a fugitive complaint before a governor's warrant issues, works on a similar logic within the very different framework of interstate rendition.
