Norris v Government of United States of America

Extradition challenges based on article 8 do not attract a separate legal “exceptionality” threshold; rather, the correct test is proportionality, balancing the individual interference with family/private life against the public interest in extradition — which is a powerful and constant factor so that only consequences of exceptionally serious weight will ordinarily outweigh it.

The appellant resisted extradition to the United States on article 8 grounds. The Supreme Court considered the legal approach judges must adopt under the Extradition Act 2003 when assessing whether extradition is compatible with Convention rights, in particular whether a claimant must show “exceptional” circumstances. The Court reviewed Strasbourg and domestic authorities, identified distinctions between "foreign" and "domestic" Convention cases, and addressed subsidiary issues: relevance of the gravity of the alleged offence, the interests of family members other than the extraditee, and whether prosecution in the requesting state (or here) is material. It applied those principles to the facts and dismissed the appeal, upholding the decision of the Divisional Court and the District Judge.

1. Disposition. The appeal is dismissed. The District Judge’s and Divisional Court’s conclusions that extradition of the appellant was compatible with article 8(1)–(2) are affirmed. ([2010] UKSC 9 paras 82–83.)
2. Principle of test. There is no separate legal requirement to demonstrate "exceptional circumstances" before article 8 will bar extradition; the proper inquiry is proportionality, requiring a balance between the interference with family/private life and the legitimate aim under article 8(2). However, the public interest in honouring extradition obligations is a powerful and constant factor in that balancing exercise, so that only consequences which are exceptionally serious will normally outweigh it. (paras 11–13, 50–56, 91–96.)
3. Domestic v foreign distinction. The Court emphasises the importance of distinguishing "foreign" cases (where treatment in the receiving state is alleged to infringe Convention rights) from "domestic" cases (where the interference is to rights enjoyed within the requested state). The approach to proportionality differs by context: the Strasbourg jurisprudence treats foreign cases as exceptional, while domestic cases require a fact-sensitive proportionality assessment. (paras 15–31, 34–38.)
4. Subsidiary rules. (a) The gravity of the alleged offence can be a relevant factor in the proportionality assessment; very low-gravity offences may form part of a combination of features making extradition disproportionate. (paras 14(i), 62–63.) (b) Family rights must be assessed for the family unit, not solely from the extraditee's viewpoint; the impact on other family members (notably children or incapacitated dependants) is relevant. (paras 14(ii), 64–66.) (c) The mere possibility of prosecuting the alleged offence domestically is rarely decisive; it is a potential factor but only likely to be relevant in marginal cases. (paras 14(iii), 66–67.)
5. Application to facts. Applying the principles to the appellant’s health, age, length of marriage, delay and the nature of the obstruction charges, the Court concluded that, although the extradition would cause serious interference with family life, the public interest in extradition outweighed those interferences and did not reach the exceptionally serious threshold required to render extradition disproportionate. The appeal is dismissed and extradition order stands. (paras 68–83, 93–94.)
6. Guidance for judges. Extradition judges should identify and weigh relevant facts and may note that the public interest in extradition is substantial; where the interference with Convention rights is not exceptionally serious the judgment may be brief, but substantial and careful reasoning is required where the interference may be exceptional. (paras 58–66, 108–115.)

• Divisional Court (Administrative Court): decision reported as [2009] EWHC 995 (Admin); Divisional Court dismissed the article 8 challenge and was affirmed on this appeal.
• District Judge: initial extradition hearing and order (referred for reconsideration after earlier House of Lords decision on price-fixing); District Judge's order affirmed by Divisional Court and this Court.
