Krzysztof Lukasik v Circuit Court, Praga in Warsaw (A Polish Judicial Authority)

In an extradition appeal based on Article 8, the appellate court must focus on whether the decision was wrong, while respecting primary factual findings. A judge should ordinarily identify the factors favouring and opposing extradition and then conduct a reasoned balance-sheet assessment. Material errors in evaluating unchallenged expert evidence, or failure to weigh relevant factors cumulatively, may make the overall proportionality decision wrong. The best interests of an affected child are a primary consideration, although they may be outweighed by the public interest in extradition. Where the first-instance reasoning is defective, the appellate court may conduct the proportionality assessment afresh on the current facts.

The appellant challenged an extradition order made by District Judge King at Westminster Magistrates’ Court on 23 March 2023. Poland sought his extradition under a conviction warrant to enforce a cumulative sentence of two years and three months for drug-supply, drug-possession and driving-while-disqualified offences.

The sole remaining ground concerned Article 8 rights, particularly the likely effect of extradition on the appellant’s son, S, who was 16 at the original hearing and had a history of serious mental-health difficulties. An unchallenged expert report concluded that S would likely suffer severe or devastating harm if separated from his father. The issue was whether the District Judge’s decision to order extradition was wrong.

1. Appeal dismissed. The District Judge’s extradition order was upheld. The High Court also concluded, on a fresh assessment, that extradition was proportionate and should be ordered.
2. The appellate question under section 27(3) of the Extradition Act 2003 was whether the District Judge had reached the wrong decision. Errors or omissions in the reasons do not automatically establish that the proportionality decision itself was wrong, but the appellate court must stand back and assess whether crucial factors should have been weighed differently. This approach was applied in Celinski and Love v USA.
3. The District Judge failed in form and substance to conduct the balance-sheet exercise described in Celinski. He considered factors individually and repeatedly asked whether each factor was sufficient to prevent extradition, rather than identifying and weighing the factors for and against extradition cumulatively.
4. The District Judge also failed properly to evaluate Dr Crumpton’s reasoned and unchallenged expert opinion. He misread the report, treated clinically significant assessment results as unhelpful, and gave insufficient weight to S’s exceptionally fragile mental health and the cumulative effect of his earlier experiences.
5. The High Court was entitled to conduct the balancing exercise afresh on the facts at the hearing, including that S had since turned 18. The public interest in honouring extradition arrangements, the appellant’s fugitive status, mutual confidence in the foreign judicial authority, the unserved consolidated sentence and multiple offences weighed in favour of extradition. The seriousness of the impact on S, the less serious nature of the offences, financial consequences and the appellant’s mental-health concerns weighed against it.
6. The best interests of a child were a primary consideration, following H(H) v Deputy Prosecutor of the Italian Republic, Genoa, but they were not decisive. S could return to Poland and live with his grandfather, and his age, previous relationship with his grandfather and continuing ability to maintain contact with his father reduced the weight of the alleged harm. The factors favouring extradition decisively outweighed those against it.

• High Court (Administrative Court): The appeal against the extradition order was dismissed. The court conducted its own Article 8 proportionality assessment and concluded that extradition should be ordered.
• Westminster Magistrates’ Court: District Judge King ordered extradition on 23 March 2023.
