Case Law
Extradition, nationality discrimination and freedom of expression: leave to appeal conditionally granted in Assange v United States
✕
Summary
Extradition may be subject to appeal where the requested person establishes an arguable risk of prejudice at trial by reason of nationality, including where such prejudice may affect access to fundamental constitutional protections in the requesting State. In such circumstances, issues under Article 10 ECHR (freedom of expression) may arise, but only insofar as they are consequential upon the risk of discriminatory treatment. Extradition may also be challenged where assurances provided by the requesting State are insufficient, particularly in relation to the death penalty and the rule of specialty, with the court entitled to require further guarantees before determining whether the appeal should proceed. By contrast, the prohibition of extradition for political offences contained in an unincorporated bilateral treaty does not confer directly enforceable rights in domestic law, nor can it operate as an independent bar to extradition under the Extradition Act 2003. The statutory framework constitutes an exhaustive code, and extradition must be ordered unless a specific statutory bar is established. Finally, at the leave stage, the appellate court is not concerned with determining the merits of the grounds, but only with whether they disclose a real prospect that the lower court’s decision was wrong.

Surrender to Italy refused: conviction in absentia did not amount to deliberate absence from trial
✕
Summary
The case concerned a European Arrest Warrant issued by the Public Prosecutor’s Office of the Court of Pordenone, Italy, seeking the surrender of the requested person to serve a one-year sentence imposed after a trial held in his absence. The requested person had been informed in 2015 that he was under investigation and had elected an address in Italy, but he later moved to the United Kingdom without notifying the Italian judicial police; he was never officially informed that prosecution had commenced, nor notified of the date and place of trial. The Supreme Court held that “deliberately absented himself from his trial” under section 20(3) of the Extradition Act 2003 must be understood consistently with Article 6 ECHR as requiring an unequivocal waiver of the right to be present at trial. Mere lack of diligence in failing to keep the authorities informed of an address was not enough, especially where the requested person had not been charged, had not been told that proceedings had begun, and had not been warned that trial could proceed in his absence. The appeal was allowed, the extradition order was quashed, and the requested person was discharged.

Post-Brexit surrender to the United Kingdom upheld under the TCA subject to a life-sentence review guarantee
✕
Summary
Greek Supreme Court (Areios Pagos) Decision No. 158/2024 – Brief SummaryIn Decision No. 158/2024, the Greek Supreme Court (Areios Pagos) dismissed the appeal of a British national against a decision authorising his surrender to the United Kingdom for prosecution on multiple serious offences, including sexual offences against minors, assault, and threatening behaviour.The Court held that, following Brexit, surrender proceedings between Greece and the United Kingdom are governed exclusively by the EU–UK Trade and Cooperation Agreement (TCA), which replaced both the European Arrest Warrant framework and the 1957 European Convention on Extradition in relations between the UK and EU Member States.The Supreme Court found that the UK arrest warrant complied with all formal and substantive requirements of the TCA, including a sufficiently detailed description of the alleged offences, the applicable legal provisions, and the potential penalties. It emphasised that the executing judicial authority is not required to examine the merits of the criminal accusations but only to verify compliance with the surrender conditions laid down in the Agreement.The Court rejected the appellant's arguments concerning insufficient information, proportionality, statute of limitations, and alleged risks of unfair treatment or inhuman conditions in Scotland. In particular, it held that the limitation defence under Article 601(1)(d) TCA was inapplicable because the alleged offences had been committed abroad by a foreign national and therefore did not fall within Greek criminal jurisdiction, which means that the statutes of limitation under Greek law does not pose a reason to deny extradition request.Finally, the Court concluded that none of the mandatory or optional grounds for refusing surrender under the TCA were applicable. It therefore upheld the execution of the UK arrest warrant, maintained the requested person's detention pending surrender, and ordered him to pay the procedural costs of the appeal.

Extradition to the United Kingdom found inadmissible due to insufficient assurances on detention conditions
✕
Summary
The case concerned a request for extradition from Germany to the United Kingdom under the EU–UK Trade and Cooperation Agreement, based on a TCA arrest warrant issued by Westminster Magistrates’ Court for alleged drug trafficking and money laundering conspiracies. The requested person objected to extradition on the ground that prison conditions in England and Wales, including overcrowding, staff shortages and violence, could expose him to inhuman or degrading treatment contrary to Article 3 ECHR. The Karlsruhe Higher Regional Court requested specific, binding assurances and detailed information on the prisons in which the requested person would be held, including cell space, occupancy, sanitation, ventilation, outdoor exercise, activities and medical care. The United Kingdom authorities provided only general information and did not identify the specific detention facilities or give the requested guarantees within the deadline set by the Court. As a result, the Court held that it could not be assumed with sufficient certainty that the requested person would be detained in humane conditions, declared extradition currently inadmissible, revoked the TCA extradition warrant and ordered his immediate release.

Extradition request from Japan certified: challenge to special extradition arrangements and diplomatic request rejected
✕
Summary
The case concerned judicial review challenges to the Secretary of State’s certification of Japan’s first extradition request to the United Kingdom, made under special extradition arrangements because no extradition treaty existed between the two States. The requested persons argued that the request was invalid because it had been issued by the Japanese National Police Agency rather than by the Government of Japan, contrary to the Memorandum of Cooperation, and because the diplomatic notes from the Japanese Embassy could not themselves constitute a valid extradition request. The Divisional Court rejected those arguments, holding that the Embassy notes expressly made or renewed a request for extradition on behalf of the Government of Japan and that the supporting police documents could properly be relied upon as part of the request. The Court further held that a formal diplomatic note issued by the Embassy could be treated as emanating from the Ambassador, acting as the diplomatic representative of Japan, and therefore satisfied the “approved way” requirement under section 70 of the Extradition Act 2003. The judicial review claim was dismissed, leaving the certification of the extradition request in place.

Agreement between the European Union and the United Kingdom and return condition required for italian citizens
✕
Summary
In the matter of a prosecution arrest warrant issued by the United Kingdom on the basis of the Partnership Agreement between the European Union and the United Kingdom of Great Britain and Northern Ireland of 24 December 2020, the optional nature of the condition of return to Italy in order to serve there the sentence eventually imposed, provided for under Article 604, letter b), of the aforementioned Agreement, results in a regime for Italian citizens that is less favourable than that laid down, for the analogous system of surrender under the European arrest warrant, by Article 19, paragraph 1, letter b), of Law No. 69 of 22 April 2005, as amended by Article 17, paragraph 1, of Legislative Decree No. 10 of 2 February 2021; therefore, in the absence of an express different request by the person concerned, the surrender is mandatorily subject to the guarantee of return and the relevant condition, where not contained in the challenged judgment, must be imposed by the Court of Cassation also “ex officio.”

On the surrender regime for requested persons and the replacement of the European Arrest Warrant following the so-called Brexit
✕
Summary
Following the withdrawal of the United Kingdom from the European Union, relations between the two—the former having become a third country—are governed by a specific agreement that entered into force on 1 May 2021. Consequently, extradition procedures do not apply where the United Kingdom requests Italy to surrender a person accused of participation in a criminal association aimed at facilitating illegal immigration. In relations between the European Union and the United Kingdom of Great Britain, following the latter’s withdrawal (so-called Brexit), the European Arrest Warrant framework has been replaced—upon the entry into force of the Trade and Cooperation Agreement—by a new model of cooperation with an autonomous legal basis, namely that set out in Title VII of the said Agreement. This model provides for a system of surrender of requested persons substantially modelled on the former regime and, being self-standing, comprehensive and detailed, is directly applicable.

EAW to the United Kingdom granted: Brexit, return guarantee and detention conditions did not bar surrender
✕
Summary
The case concerned an extradition request submitted by the United States for the prosecution of the requested person for alleged wire fraud and aggravated identity theft in connection with the electronic filing of false tax returns. The requested person challenged the admissibility of extradition before the Supreme Court, arguing that the documents submitted by the United States were insufficient, that the facts for which extradition had been declared admissible were not clearly identified, and that the requirement of double criminality was not met. The Advocate General considered that the extradition documents were sufficient, including as to U.S. jurisdiction and the applicable statutory provisions. Although the description of the facts in the lower court’s decision was not entirely clear, the Advocate General considered that this could be remedied by reading the decision as referring to the facts set out in the supporting affidavit. The Advocate General further found that the alleged conduct corresponded under Dutch law to fraud and forgery, and recommended dismissal of the appeal; the Supreme Court followed that conclusion under Article 81(1) RO.

Withdrawal of the extradition request and revocation of seizure
✕
Summary
The withdrawal of the extradition request entails the revocation of real precautionary measures, with the consequent return to the rightful owner of the assets subject to seizure, given that—pursuant to Article 6(2) of the European Convention on Mutual Assistance in Criminal Matters of 20 April 1959—the requesting State is not entitled to dispose of assets obtained through the execution of a letter rogatory that has subsequently been withdrawn. (In the present case, the Court quashed without remittal the order by which the Court of Appeal had ordered the return of the seized assets, limited to those not yet transferred to the requesting authority).

High Court bail powers in extradition proceedings are subject to the statutory prohibition and limited exceptions
✕
Summary
The requested person applied for bail while awaiting a committal hearing on the United Kingdom’s request for her extradition for alleged theft offences. The High Court held that its power to grant bail under section 97(1) of the Criminal Procedure Code was circumscribed by the express prohibition applicable to persons arrested under the Extradition Act in section 95(1)(c). Bail remained possible only within the limited statutory exception for juveniles or sick or infirm persons, and the general High Court provision could not be used to circumvent that restriction. The Court added that, even assuming a broader statutory or inherent power existed, bail in extradition proceedings should be granted only for special reasons; as none were established, the application was dismissed.

Article 8 and children’s best interest in extradition: family life may bar surrender only after a strict proportionality assessment
✕
Summary
SUMMARY (English) The case concerned three joined European Arrest Warrant appeals in which the requested persons resisted extradition on the basis that surrender would disproportionately interfere with the Article 8 ECHR rights of their dependent children. The Supreme Court clarified that, although there is a constant and weighty public interest in extradition, there is no separate test of exceptionality and the court must carefully assess the actual impact of extradition on family life. Children’s best interests must be treated as a primary consideration, but they are not paramount and may be outweighed by the public interest in extradition, particularly where the offences are serious. On the facts, the Court allowed the appeal of the Polish mother, whose extradition for relatively minor and old dishonesty offences would cause severe harm to her youngest children. By contrast, the appeals of the parents sought by Italy for serious drug-trafficking offences were dismissed, the mother unanimously and the father by majority, because the public interest in extradition outweighed the Article 8 interference.
