Welsh & Anor v Secretary of State for the Home Department & Anor

Extradition arrangements must be assessed by reference to the statutory requirements, while allowing for reasonable differences between foreign legal systems and UK practice. Dual criminality under the Extradition Act 2003 concerns whether the conduct alleged would constitute an offence in the United Kingdom. It does not require precise equivalence between foreign and domestic offences.

For specialty, the court must form its own view of whether a person would be dealt with for a non-extradition offence. Evidence of other conduct may be used to prove or sentence the extradition offence, provided the person is not thereby tried or punished for that other offence. Case-specific undertakings may form part of the relevant arrangements, although they did not alter the outcome here.

The appellants, a UK citizen and a US citizen, appealed against District Judge Pratt’s decisions under sections 78 and 87(3) of the Extradition Act 2003, and against the Secretary of State’s extradition orders under section 108. The United States sought their extradition for conspiracy, fraud and related offences arising from an alleged advanced-fee investment fraud.

The appeals concerned alleged defects in arrest warrants and extradition charges, dual criminality, and specialty. In particular, the appellants argued that United States prosecutors and courts might use money-laundering conduct, conduct occurring in the United Kingdom, flight, or the fact of contesting extradition to support additional charges or increased sentences.

1. Form and procedure. The warrants were valid for the purposes of section 78. The signatory could properly be inferred to have signed on behalf of the Clerk, and the status of the signatory could be proved by other evidence. The use of “et al” did not invalidate the warrants where the indictment and warrants were served together and the appellants understood the allegations. Typographical references to the female appellant as “him” did not affect identity or validity.
2. Dual criminality. The conspiracy count was an offence against United States law. The alleged forgery satisfied dual criminality because the conduct constituting the United States mail-fraud offence would constitute forgery in England. Section 137 focuses on whether the conduct constituting the foreign offence would also constitute an offence under UK law. Precise equivalence between the ingredients of the foreign and domestic offences is unnecessary. The court relied on the approach in Office of the King's Prosecutor, Brussels v Armas [2005] UKHL 67.
3. Specialty and prosecution. Section 95 requires the court to consider whether, under law or arrangement, the appellants could be dealt with only for offences within section 95(4). The United States authorities and courts were shown to respect express limits imposed by the United Kingdom. A superseding indictment for offences outside those limits would breach specialty, and Home Secretary consent under section 95(4)(c) could not be inferred. The authorities relied on by the appellants, including US v LeBaron 156 F.3d 621, illustrated adherence to specialty when properly understood.
4. Evidence and sentencing. Specialty does not prevent the trial court admitting evidence of conduct relating to offences for which extradition was refused, where the evidence is used to prove the extradition offence. Nor does it prevent sentencing by reference to conduct relevant to the gravity or manner of commission of that offence. The United States approach was wider than UK practice but fell within the flexible and purposive meaning of “dealt with” in section 95. The appellants would be punished for the extradition offences, not for money laundering, foreign conduct, or failure to appear as separate offences.
5. Undertakings and disposition. The post-decision undertakings were admissible and could be considered as part of the arrangements. They did not materially alter the analysis. The appeals were dismissed.

The judgment records appeals from District Judge Pratt’s decisions of 22 March and 19 April 2005 and from the Secretary of State’s extradition orders of 17 and 19 October 2005. The Divisional Court dismissed the appeals.
