Provisional Arrest and Provisional Warrants in Extradition Cases

What has actually happened: provisional arrest, a warrant, or final surrender?

Three documents may sound alike but perform different jobs. The foreign arrest warrant or conviction is usually the foundation of the requesting state's case. A provisional-arrest request asks another state to secure the person before the complete extradition papers arrive. A domestic provisional warrant, where the requested state's law provides one, authorises an arrest there. None of these is a final order delivering the person to foreign custody.

A person detained at an airport may know only that an international alert was mentioned. Ask for the actual legal instrument: a local arrest warrant, court order, statutory certificate, or another lawful arrest power; the identity of the requesting state; the alleged conduct; and the recorded arrest time. INTERPOL expressly says that a Red Notice requests location and provisional arrest but is not itself an international arrest warrant. National law determines whether and how officers may act on it.

Before discussing a deadline, identify the two countries, the treaty applicable between them on the relevant date, any reservations or protocols, and the requested state's implementing law. A 1957 Convention deadline, a UK statutory deadline and an EU surrender deadline are not alternative numbers to choose from; they belong to different procedures. The requested state decides the arrest under its own law even where a treaty authorises a foreign request.

Under the 1957 European Convention, what must the urgent request contain?

Article 16 of the European Convention on Extradition (ETS No. 024) allows the requesting state's competent authorities, in urgency, to seek provisional arrest. The request must say that a warrant, enforceable conviction or equivalent document described in Article 12(2)(a) exists and that a formal extradition request is intended. It must identify the offence, its time and place, and, as far as possible, the person. Article 16(3) allows specified transmission channels, including INTERPOL or another accepted means providing a written record. It does not permit an officer to dispense with the requested country's arrest law.

Article 16(4) provides that provisional arrest may end if the full request and Article 12 documents have not arrived within 18 days after arrest and that it must not in any event exceed 40 days as provisional arrest under that provision. It also leaves open provisional release at any time, with measures against flight. Article 16(5) says release does not bar a later re-arrest and extradition if the formal request arrives. The difference between “may” at day 18 and “shall not exceed” at day 40 matters; neither phrase guarantees freedom from a separate, newly established lawful ground for custody.

The Convention's Article 22 leaves procedure to the law of the requested state except as the Convention provides otherwise. Before putting the 18/40-day argument to a judge, verify treaty membership, bilateral modifications, applicable additional protocols, declarations, the local authority authorised to receive papers, and whether the papers truly satisfy Article 12. A mere statement that documents were sent may not answer a rule requiring actual receipt. The Council of Europe's Treaty Office supplies state-by-state status and reservations; there is no reliable country-independent calculator.

Why a UK provisional warrant is not the same as an INTERPOL alert

For a UK Part 2 request involving a category 2 territory, section 73 of the Extradition Act 2003 provides for a provisional warrant based on written information on oath and the statutory evidence threshold. In England and Wales, a justice of the peace may issue it; in Scotland, the provision substitutes a sheriff acting on an application by a procurator fiscal, and in Northern Ireland the information requirement is adapted to a complaint. Section 74 governs the person arrested under the warrant: a copy must be given as soon as practicable and the person brought before the appropriate judge as soon as practicable, subject to statutory exceptions. The judge decides remand in custody or on bail and may later grant bail.

Under section 74(10)–(11), the judge must order discharge if the section 70(9) documents have not been received by the judge within 45 days starting with the day of arrest, or within any longer period permitted by a designation order for that territory. If the person is not brought before the appropriate judge as required and applies for discharge, discharge is mandatory; failure to provide the warrant copy may support discretionary discharge. These defects have different consequences, so not every procedural irregularity is a breach of the 45-day period.

A separate UK arrest-without-warrant route, introduced by the Extradition (Provisional Arrest) Act 2020, now appears in sections 74A–74E and Schedule A1 of the 2003 Act. It currently covers specified Category 2 territories—Australia, Canada, Iceland, Liechtenstein, New Zealand, Norway, Switzerland and the United States—but Schedule A1 must be checked as at the arrest date. The National Crime Agency (NCA) must certify a qualifying request; an INTERPOL Red Notice or diffusion may supply the request, but the alert alone does not authorise arrest. At the first appearance, section 74D requires the judge to decide whether a section 73 warrant would be justified; if not, the person must be discharged. An adjournment to obtain evidence is permitted only on statutory conditions and may not exceed 72 hours in total, excluding the days specified by section 6(8A); the judge may remand the person in custody or on bail during it. Section 74E governs the next steps and defects. Importantly, section 74E(4) cross-refers to section 74(11), so the same 45-day (or designated longer) deadline for the section 70(9) documents applies.

What the United States example proves—and what it does not

When a foreign state seeks extradition from the United States, 18 U.S.C. § 3184 identifies the judicial officers who may issue a warrant on a sworn complaint in a qualifying treaty or statutory case. Section 3184 is a domestic warrant-and-hearing mechanism, not a universal treaty deadline for pre-request custody. For a person arrested in the United States on a foreign request, counsel must identify the applicable treaty, the local warrant and the custody record. The § 3184 proceeding does not itself decide final surrender: under § 3186, the Secretary of State has the function of ordering delivery after judicial commitment.

US bail is not governed by the same presumption as ordinary criminal trial bail. In Wright v. Henkel, 190 U.S. 40 (1903), the Supreme Court did not exclude release under special circumstances, while finding no error in refusal on the record. The district judge handling the extradition matter considers an application under that restrictive framework, with any binding circuit precedent and later decisions checked locally. No representation should promise bail simply because the person has a fixed address or offers a bond.

18 U.S.C. § 3188 applies after a person has been committed for rendition or admitted to bail. If the person has not been surrendered and delivered within two calendar months after commitment, with the time actually required to convey the person from the jail to the foreign government’s agent added on, the committing judge must order discharge on the person’s application and reasonable notice to the Secretary of State unless sufficient cause is shown. This is not a general two-month limit for the initial provisional-arrest stage; the statutory trigger and transport-time allowance are specific.

Do EU European arrest warrants have the same emergency detention clock?

No. The European arrest warrant (EAW) is a judicial surrender instrument between EU Member States, governed principally by Framework Decision 2002/584/JHA and national implementing law. It is not the Convention Article 16 pre-request mechanism. Article 12 addresses detention or provisional release by the executing judicial authority according to national law, taking steps necessary to prevent absconding. Under Article 17, the usual target for a final execution decision is 10 days after consent or 60 days after arrest otherwise, with a possible further 30 days in specified circumstances. These are decision-making time limits, not an automatic release command.

In Minister for Justice and Equality v Lanigan, C-237/15 PPU (Grand Chamber, 16 July 2015), the Court of Justice held that the executing authority still has to decide after Article 17 periods expire. Continued custody can remain lawful under national law if the overall period is not excessive and the procedure has been pursued diligently; the court must assess the individual case. The executing national court applies this binding EU interpretation, together with relevant later CJEU jurisprudence and domestic rules. It would be wrong to cite an EAW 60-day decision deadline as a 60-day cap for Convention provisional arrest—or to demand automatic EAW release solely on expiry.

When a family member says “European warrant”, counsel should establish whether the document is an EAW, a UK category 2 provisional warrant, or a foreign warrant circulated through INTERPOL. For a detailed EAW defence pathway, see European arrest warrant representation; that separate page owns the broader surrender arguments.

The second clock starts after surrender: specialty is a different protection

Specialty concerns what the receiving state may do about earlier offences other than those for which the person was surrendered. It is not a rule about how long the requested state may hold someone before receiving papers. Article 14 of the 1957 Convention is a key example; Article 27 of the EAW Framework Decision uses a related, but not identical, scheme. A person arrested provisionally today normally needs a custody argument today, not a post-transfer specialty objection dressed up as a release deadline.

The 45-day specialty exception is not the Convention’s 40-day provisional-arrest clock. Under Convention Article 14(1)(b), it applies only if the person had an opportunity to leave and did not leave within 45 days after final discharge, or returned after leaving. EAW Article 27(3)(a) has a related 45-day exception after final discharge or return, but does not use the same express “opportunity to leave” wording. The EAW also contains other exceptions, including specified non-custodial outcomes. Under Article 27(4), a separate consent request must include the information required by Article 8(1) and a translation; the executing judicial authority must decide within 30 days of receipt, checking whether the new offence is itself surrenderable and whether mandatory or optional non-execution grounds apply. These are post-surrender rules, not a way to calculate pre-request custody.

Later CJEU case law limits broad assumptions about specialty consent. In Openbaar Ministerie (C-510/19, 24 November 2020), the Court held that consent under Article 27(4) must come from an executing judicial authority meeting EU-law independence requirements; a prosecutor subject to executive instructions is not enough. In OE (C-142/22, 6 July 2023), the Court held that a defect in the authority that issued the original EAW does not by itself prevent later consent where the request is made by a competent issuing judicial authority. The earlier judgments still matter: Leymann and Pustovarov (C-388/08 PPU) requires comparison of the offence elements and factual information in the EAW with later procedural documents; a changed label or more precise description alone does not automatically create a different offence. XC (C-195/20 PPU, 24 September 2020) ties the relevant specialty question to the second surrender when departure from the first state was voluntary and a second EAW led to surrender. For detailed specialty litigation, see the page on the rule of specialty after extradition.

Which challenge should be made now, and before whom?

Wrong person or document: Compare the full identity data with the domestic warrant or certificate, the requesting-state judicial document and the treaty's minimum information. Present discrepancies promptly to the domestic judge controlling custody; ask that the court see the original or authenticated evidence as the applicable procedure allows. Identity questions are different from guilt or innocence at trial.

No lawful domestic basis or delayed first appearance: Ask the custody court to identify the statutory arrest power and examine the arrest record. In the UK section 74 example, different failures support different discharge applications; in US proceedings the § 3184 judge examines the complaint and warrant. A foreign police message alone does not resolve those domestic requirements.

Request documents not received in time: Determine exactly what had to be received, by whom, and by what trigger date. Obtain the receiving authority's log if possible. Submit the treaty/statute-specific discharge application to the judge with custody jurisdiction. A favourable ruling may end that custody basis without finally disposing of a later extradition request.

Need for release pending proceedings: Provide verified residence, health or caregiving evidence, a proposal addressing attendance, and information that counters a substantiated flight concern. The hearing forum and test differ: UK appropriate judge under the 2003 Act; US extradition judge under Wright and governing circuit law; EAW executing judicial authority under national legislation read consistently with Article 12 and Lanigan. Even when the detention clock has not expired, proportionality and legally available alternatives may matter.

Threatened immediate transfer: Check whether the formal request has arrived, whether any extradition decision exists, and whether the relevant domestic appeal or urgent stay procedure can halt delivery. Filing a challenge is not necessarily self-suspending. A custody application and an appeal against extradition answer different legal questions; use cross-border arrest and surrender representation for the broader sequence.

The first response file: what a detained person or family can actually gather

• Full name, aliases, birth data, citizenship and any concrete indication that police identified the wrong person.
• Exact arrest date, local time, location, custody number and the document officers relied on; note all later custody changes.
• Both states, the foreign issuing court, charge descriptions, original dates of alleged acts and current domestic authority.
• Copies of the provisional request, domestic warrant or certificate, first-appearance record, interpreter record, and remand or bail orders.
• Evidence of where and when the complete request reached the legally designated authority, distinguishing dispatch from receipt.
• For release: stable address, proposed reporting arrangements, medical documents where relevant and facts bearing on flight risk.
• If surrender already occurred: the actual surrender decision, consent or waiver transcript, and a comparison of old and new charges.

Make a chronological list, not a prediction. Date calculations can differ over inclusive day-counting, time zones, holidays and implementing provisions; domestic counsel should confirm the governing rule before asserting that a deadline has passed. Family members should preserve copies and relay information through the detained person's chosen lawyer rather than assume they have an independent right to every confidential case document.

Two practical errors that can change the answer

First, a release order for failure to receive papers on time does not necessarily cancel the foreign arrest warrant or bar a properly supported later request. Article 16(5) says so expressly for the 1957 Convention. A person should obtain the operative local discharge order, check whether other lawful custody grounds exist, and understand what the order actually determines.

Second, consent to an expedited extradition or EAW surrender is not the same thing as a knowing waiver of all subsequent specialty protections. Whether and how waiver operates depends on the instrument, its implementation, the precise written declaration and safeguards. Never infer waiver merely from a short hearing note; preserve the transcript and ask the receiving-state lawyer to test the later charge against the authorised surrender.

If someone is already detained, a focused review of the arrest record, controlling instrument and receipt dates is more useful than a generic prediction. For an individual assessment, send the available documents and the country pair securely.
