HH v Deputy Prosecutor of the Italian Republic, Genoa

In extradition proceedings engaging the family-life rights of dependent children, the children's best interests are a primary consideration and must receive careful, fact-sensitive assessment. Article 8 requires proportionality, not an exceptionality test. The court must balance the gravity of the interference with family life against the strong public interest in extradition, whose weight varies with the seriousness of the offending, delay and other circumstances.

No prescribed order of reasoning is mandatory, provided every relevant interest is properly evaluated. Extradition will usually prevail, especially for serious cross-border crime, but may be disproportionate where relatively minor, old offences and prosecutorial delay are outweighed by exceptionally severe harm to young children.

These conjoined appeals under the Extradition Act 2003 concerned parents of young children. Italy sought HH and PH, British nationals convicted of serious cross-border drug trafficking. Poland sought F-K, the primary carer of five children, for older dishonesty offences. The evidence showed that extradition would cause grave harm to the younger children.

The Administrative Court dismissed HH's and PH's appeals in [2011] EWHC 1145 (Admin) and F-K's appeal in [2012] EWHC 25 (Admin). The certified question was how children's article 8 interests should be safeguarded in extradition proceedings, and whether Norris v Government of the United States of America (No 2) required modification in light of ZH (Tanzania) v Secretary of State for the Home Department.

F-K's appeal allowed unanimously; HH's appeal dismissed unanimously; PH's appeal dismissed by a majority of six to one.

1. The court was agreed that article 8 requires a proportionality assessment, not an exceptionality test. The likely rarity of a successful article 8 objection describes the probable outcome of proper balancing; it does not create a legal threshold. The court must assess the actual gravity of the interference with each family member's rights against the public interest in extradition. The latter is consistently powerful, particularly for serious cross-border crime, but its weight varies with the seriousness and age of the offences, delay, fugitive conduct and the circumstances of the request.

2. The best interests of an affected child are a primary consideration. They require distinct and careful evaluation and cannot be discounted because of parental wrongdoing for which the child bears no responsibility. A majority, reflected in the reasons of Lord Mance, Lord Judge and Lord Wilson, rejected any mandatory order in which the competing considerations must be addressed. What matters is that the court has substantively evaluated them and struck a fair balance.

3. Where extradition of both parents, or a sole or primary carer, is sought, the court ordinarily needs evidence about the likely effect on each child, proposed care arrangements, ways of maintaining contact and measures capable of mitigating separation. Separate representation will rarely be necessary. The court and parties must nevertheless obtain enough information to treat the children's interests as a primary consideration.

4. F-K's relatively old and comparatively minor dishonesty allegations, substantial official delay and the severe likely harm to her two youngest children made extradition disproportionate. Her appeal was allowed.

5. HH's leading role in a persistent, professional drug-smuggling conspiracy, her sentence and her flight in breach of bail outweighed the interference with the children. Her mental condition did not make extradition oppressive. Her appeal was dismissed.

6. PH's case involved exceptionally serious interference with the children, but the majority held that the gravity of his repeated drug trafficking, his active professional role, his breach of Italian bail and the imperative against safe havens outweighed that harm. The requested court could not reassess Italian sentencing or release arrangements, or defer surrender in the hope of a later request. Lady Hale dissented on PH, considering that the present harm, especially to the youngest child, justified discharge while leaving Italy free to seek extradition later.
