AN, R (on the application of) v Secretary of State for the Home Department

Prison conditions engage Articles 3 and 8 of the Convention only where the treatment, interference or risk reaches the applicable legal threshold. The assessment is fact-sensitive and must account for duration, effects, the prisoner’s health and the legitimate purposes of detention. A prisoner’s particular vulnerability, including mental illness, requires increased vigilance, but does not make every detrimental condition unlawful.

Security measures may be proportionate where based on a genuine and reasonable concern and where less restrictive accommodation is unavailable or unsuitable. The court must assess the evidence itself, including expert evidence. Positive obligations require reasonable and proportionate measures to avert a real risk of violation; they do not require prison authorities to await actual disorder.

The claimant, a prisoner at HMP Belmarsh with PTSD and depression following mistreatment in Syria, challenged his placement in a single cell within the healthcare centre between 29 April and 13 May 2008.

He alleged breaches of the negative and positive obligations under Articles 3 and 8 of the Convention. He argued that the placement caused or aggravated serious psychological distress, created a real and immediate risk of unlawful treatment, and was disproportionate. The Secretary of State relied on security concerns, including alleged extremist influence over other prisoners and the limited availability of shared healthcare accommodation.

The central issues were whether the placement crossed the Article 3 threshold, unlawfully interfered with Article 8, or resulted from a failure to take reasonable and proportionate protective measures.

1. Application dismissed. The claimant’s placement in a single cell, while remaining in the healthcare centre and able to associate with other prisoners during the day, was not unreasonable or disproportionate. The security concerns were genuine and had a sufficient evidential basis. The authorities were not required to await actual disorder before intervening.
2. The court assessed the evidence itself, including the expert evidence. It preferred Dr Cumming’s assessment of the claimant’s PTSD and depression, given his greater clinical exposure and the consistency of his opinion with the contemporaneous medical records. The claimant’s solitary confinement in Syria was significant, but was not the principal stressor and was materially different from the conditions at Belmarsh.
3. The placement did not breach the negative obligation under Article 3. The treatment fell well short of torture or inhuman or degrading treatment. The claimant’s distress, although genuine, did not reach the necessary level of severity, and the measures pursued a legitimate security purpose in a proportionate manner.
4. There was no breach of the positive obligation under Article 3. The prison system and the steps taken by medical and custodial staff were adequate to protect the claimant’s Convention rights. His specific reaction to single-cell accommodation was repeatedly considered by persons with relevant knowledge and expertise.
5. There was no breach of Article 8. The evidence did not establish a significant interference with private life or long-lasting deterioration in mental health. Nor did the authorities fail to take reasonable and proportionate steps to avert a Convention violation.
