Notable Cases

Hemmati & Ors v Secretary of State for the Home Department [2019] UKSC 56
Led by Michael Fordham QC. Supreme Court held that Home Secretary had failed to institute into domestic law and apply the high level of protection provided by EU law against the detention of asylum seekers. That meant that the appellants and any asylum seeker who had been detained pending their removal to Member States between 2014 – 2017, were entitled to damages for the tort of false imprisonment. Press coverage: The Guardian and Independent.

Idahosa v R [2019] EWCA Crim 1953

MR (Pakistan) & Anor v Secretary of State for Justice & Ors [2019] EWHC 3567
Led by Hugh Southey QC. Judicial review of the scheme governing the detention of immigration detainees held in the prison estate where the Prison Rules fail to provide equivalent protection or mechanisms to discover and release detainees who are victims of torture, compared to the rules governing immigration detention centres.

Foley v Secretary of State for Justice & Anor [2019] EWHC 488 
Challenge to the decision by the Secretary of State to retain Claimant in custody pursuant to an indeterminate sentence of imprisonment for public protection, depriving him of removal from prison through the "Tariff-Expired Removal Scheme" ("TERS").
