Case Law
Digital evidence (WhatsApp messages) in extradition proceedings: interception law not in force and remittal ordered (Andrew Bennett extradition case)
✕
Summary
The case concerned extradition proceedings initiated by the United States against a Belizean attorney accused of participating in money laundering activities connected to drug trafficking. The extradition request relied in part on WhatsApp communications exchanged with an undercover DEA agent, which the lower courts had previously considered unlawfully obtained under Belize’s Interception of Communications Act and therefore unconstitutional. Before the Caribbean Court of Justice, it emerged that the statute relied upon by the lower courts had not yet entered into force at the relevant time, rendering the prior findings per incuriam. The Court held that the constitutional issues concerning the use of WhatsApp communications without judicial authorisation had not been properly argued and should not be resolved hypothetically on appeal. The decisions of the lower courts were therefore set aside and the matter remitted to the High Court for reconsideration of the constitutional questions.

Reversal and remandExtraditionExtradition to the United States: Court of Appeal failed to obtain individualized information on detention conditions
✕
Summary
The case concerned a United States request for extradition from Italy for prosecution on a charge of conspiracy to commit money laundering. The Court of Appeal had declared the conditions for extradition satisfied, subject to the condition that any extradition detention served in Italy be credited against a sentence eventually imposed in the United States. The requested person appealed, raising several objections, including alleged defects in the extradition request, the subsequent substitution of the extradition title following a Grand Jury indictment, lack of United States jurisdiction, insufficient evidentiary basis, breach of speciality, disproportionate punishment and the risk of inhuman or degrading detention conditions. The Italian Supreme Court rejected all grounds except the complaint concerning detention conditions. It held that the replacement or formal development of the extradition title during the proceedings did not bar extradition where the factual basis remained the same and the new title was submitted before the Court of Appeal’s decision. It also held that Italian courts are not required, in extradition to the United States, to review the existence of United States jurisdiction as a ground for refusal, and that the “reasonable basis” requirement under the Italy–US extradition treaty does not require an autonomous assessment of serious evidence of guilt. The Court further rejected the argument that the maximum penalty of twenty years for money laundering conspiracy was, in itself, manifestly disproportionate. However, it found that the Court of Appeal had failed to properly address the defence submissions on detention conditions. The defence had relied not only on NGO material but also on official United States prison standards suggesting that personal space could ordinarily fall below three square metres per detainee. This was a qualified source capable of raising a potential Article 3 ECHR issue. The Court therefore held that the Court of Appeal should have sought complete, current and individualized information from the United States on the specific detention conditions that would apply in case of surrender. The judgment was annulled with remand for a new assessment limited to that issue.

Reversal and remandExtraditionCompeting EAW and extradition request require consultation of the member state of nationality and the Minister of Justice
✕
Summary
The United States requested the extradition of a Russian-German national from Italy for offences connected with the operation of a cryptocurrency exchange platform and money laundering. Germany subsequently issued a European Arrest Warrant concerning conduct allegedly overlapping with the facts underlying the extradition request. The Supreme Court quashed the decision authorising extradition because the Court of Appeal had relied on a decision issued in the separate EAW proceedings without formally introducing it into the extradition case or allowing the parties to comment on it, thereby breaching the adversarial principle. The Court further held that the requested judicial authority must activate the Petruhhin notification mechanism by informing the member state of nationality and allowing it a reasonable period to take appropriate action. In addition, where an EAW and a third-country extradition request coexist, the judicial authority must seek the prior opinion of the Minister of Justice under the EU-US Extradition Agreement before deciding which request should take precedence. The case was remitted for a new decision.

Reversal and remandExtraditionExtradition to the United States and sentencing disparity: scope of judicial review of surrender decisions
✕
Summary
The High Court of New Zealand reviewed the lawfulness of a ministerial decision ordering surrender to the United States, focusing on whether all relevant factors had been properly considered. In particular, the Court examined the significance of the disparity between the potential sentence in the requesting State and the sentence likely applicable under domestic law. While reaffirming the limited scope of judicial review in extradition matters, the Court held that surrender decisions must adequately address proportionality concerns and may be set aside where relevant considerations — including sentencing consequences — have not been properly evaluated.

Reversal and remandExtraditionCitizenship: the requested Member State must inform the State of nationality of the person sought (Petruhhin)
✕
Summary
In matters of extradition of a national of a Member State of the European Union to a third State, the requested Member State, in application of the notification mechanism outlined in the judgment of the Court of Justice of the European Union (Grand Chamber, 6 September 2016, C-182/15), is required to inform the State of nationality also where that State’s domestic law alone provides nationality as a ground for refusing surrender. This is in order to enable that State to issue, in turn, a European Arrest Warrant and request surrender for the purpose of prosecuting the same acts.

Reversal and remandExtraditionExtradition, 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.

PendingExtraditionExtradition, double criminality, tax offences and “punishability thresholds”
✕
Summary
Traditional extradition treaties refer to institutions of the criminal law of individual States — such as double criminality — for the specific purpose of allowing the requested State to assess the 'recognisability' and therefore the acceptability of the punitive claim of the requesting State, thereby ensuring the requirement of reciprocity. As regards criminal thresholds, the bilateral treaty with the United States contains no specific provisions on this point, which means that the double criminality requirement must be assessed according to the ordinary rules — that is, by way of a concrete, in concreto verification.

Reversal and remandExtraditionExtradition to USA and risk of a life sentence
✕
Summary
Under the framework governed by the bilateral treaty of 13 october 1983, the possibility that a life sentence may be imposed does not constitute a bar to the issuance of a favourable extradition decision. this is due to the existence, within the united states legal system, of various mechanisms which, in relation to individuals sentenced to life imprisonment, may allow for early release—albeit on the basis of discretionary assessments by different public authorities—or, in any event, for commutation where humanitarian grounds or progress in the rehabilitative process are established. this is without prejudice to the situation where the requested person specifically alleges the existence of a real risk of being subjected to inhuman or degrading treatment, contrary to article 3 of the European Convention on Human Rights.
