Upon arrival, he was placed on a “single unlock” regime on account of his violent and aggressive conduct in previous custody and to allow a period of time to assess his behaviour. This measure precluded him from leaving his cell when any other detainees were out of their cells. He was allowed out of his cell for around one hour a day to collect his medication, shower, make telephone calls and exercise. For the remaining time, he was locked alone in his cell. This regime continued in place until 2 February 2017. The applicant brought judicial review proceedings in the High Court invoking his Article 3 rights. His claim and subsequent appeal to the Court of Appeal were dismissed. On 9 July 2021, the Supreme Court concluded that there had been no breach of Article 3 of the Convention on account of his removal from association with other prisoners during the fifty-five day period concerned. QUESTION TO THE PARTIES Was the applicant subjected to inhuman or degrading treatment between 10 December 2016 and 2 February 2017, in breach of Article   3 of the Convention, on account of his being placed on a “single unlock” regime?
