McKinnon, R (on the application of) v Secretary of State for Home Affairs

Factual and Procedural Background

The Plaintiff seeks judicial review of the Secretary of State's decision dated 13 October 2008 to uphold an earlier order for his extradition to the United States on charges related to hacking into US Government computers. Permission for judicial review was limited to the claim that extradition would infringe the Plaintiff's rights under Article 3 of the European Convention on Human Rights ("the Convention"). An application to renew the claim under Article 8 was refused on the basis that success under Article 3 was a prerequisite.

Separately, the Plaintiff sought judicial review of the Director of Public Prosecutions' (DPP) reiterated decision, dated 26 February 2009, not to prosecute him domestically. The Court heard the applications in a combined ("rolled-up") hearing, considering the interrelation between the DPP's decision and the extradition claim.

The Plaintiff's alleged criminal conduct involved unauthorized access to and interference with numerous US Government computers, including military and NASA systems, causing significant disruption and damage. The Plaintiff was arrested in the UK in 2002 and indicted in the US. The UK authorities decided not to prosecute domestically, deferring to the US prosecution and extradition request.

Following extensive litigation, including appeals to the Divisional Court and House of Lords which upheld the extradition decisions, the Plaintiff's solicitors submitted new medical evidence establishing a diagnosis of Asperger Syndrome ("AS"), a form of Autism Spectrum Disorder ("ASD"). This diagnosis, along with expert reports detailing the Plaintiff's mental health vulnerabilities and the risks posed by extradition and incarceration in the US, formed the basis of the renewed human rights challenge.

The Secretary of State's decision letter considered the medical evidence and concluded that the Plaintiff's extradition would not breach Article 3 or Article 8 rights, relying in part on assurances from US authorities regarding medical care and treatment. The Plaintiff also challenged the DPP's refusal to prosecute domestically, arguing that prosecution in the UK would preclude extradition.

Legal Issues Presented

1. Whether the Secretary of State's decision to extradite the Plaintiff to the United States would infringe his rights under Article 3 of the Convention, prohibiting inhuman or degrading treatment or punishment.
2. Whether the Plaintiff's rights under Article 8 of the Convention, concerning private and family life, would be infringed by his extradition.
3. Whether the Director of Public Prosecutions erred in law or acted unlawfully in refusing to prosecute the Plaintiff in the United Kingdom, thereby affecting the lawfulness of the extradition process.
4. Whether the Secretary of State had a duty to seek assurances from US authorities regarding bail pending trial and repatriation to serve any sentence in the UK.

Arguments of the Parties

Appellant's Arguments

• The Plaintiff's extradition would violate Article 3 due to his Asperger Syndrome and associated mental health vulnerabilities, making detention in the US inhuman or degrading treatment.
• The Plaintiff should be prosecuted in the UK, which would preclude extradition under the rule against double jeopardy (Extradition Act 2003, section 80).
• The Secretary of State erred by failing to seek assurances regarding bail and repatriation, aggravating the risk of harm and rendering the decision disproportionate.
• The Plaintiff's Article 8 rights are also engaged and infringed by extradition, given the impact on his private and family life.

Respondent's Arguments (Secretary of State and DPP)

• The Secretary of State has the power and duty to extradite unless there is a real risk of Convention rights infringement; the evidence does not meet the high threshold under Article 3.
• The claim under Article 8 is unarguable, especially given Article 8.2 justifies extradition.
• The DPP lawfully decided not to prosecute domestically due to insufficient evidence for relevant charges and public interest considerations, particularly the complexity and location of evidence in the US.
• The DPP owes no duty to prosecute in the interests of the Plaintiff, and prosecutorial discretion is owed to the public and victims generally.
• The Plaintiff’s attempt to use prosecution as a collateral challenge to extradition is impermissible.
• The Secretary of State reasonably relied on assurances from US authorities regarding medical care and treatment, which do not indicate a real risk of inhuman or degrading treatment.

Court's Reasoning and Analysis

The Court considered the Plaintiff's Asperger Syndrome diagnosis and related expert evidence, acknowledging the mental health difficulties and risks posed by extradition and incarceration in the US. However, the Court emphasized the high threshold required to establish a breach of Article 3 in extradition cases, particularly where the alleged ill-treatment results from conditions in a foreign state rather than direct state action or deliberate infliction of harm.

The Court noted that the Plaintiff had endured stressful proceedings over several years without acute medical intervention and that his condition had not previously necessitated treatment. The Court also examined the assurances provided by US authorities regarding medical and psychiatric care, bail, and the possibility of repatriation, finding them to have substantial weight.

Regarding the DPP’s refusal to prosecute, the Court held that prosecutorial discretion is owed to the public and victims, not the defendant, and that the DPP was not under a duty to prosecute to prevent extradition. The evidence and complexity of the case justified the decision to defer prosecution to the US, where the bulk of evidence and witnesses are located.

The Court rejected the Plaintiff's argument that the Secretary of State erred by failing to seek assurances on bail and repatriation, finding no real risk of Article 3 infringement without such assurances. The Court also upheld the refusal to grant permission for judicial review on the Article 8 ground, concluding that the Plaintiff could not succeed under Article 8 having failed under Article 3, especially given the lawful and proportionate nature of the extradition.

Holding and Implications

The Court's final decision is to DISMISS the Plaintiff's claims for judicial review against both the Secretary of State and the Director of Public Prosecutions.

The direct effect is that the Secretary of State's decision to extradite the Plaintiff to the United States stands, and the DPP's decision not to prosecute domestically is upheld. The Court found no basis to interfere with these decisions, emphasizing the high thresholds for Convention breaches in extradition contexts and the proper exercise of prosecutorial discretion.

No new legal precedent was established; the decision reinforces established principles regarding the interplay of prosecutorial discretion, extradition law, and human rights protections under the Convention in the UK context.
