Notable Cases

AAA v Secretary of State for the Home Department (Rwanda) [2022] EWHC 3230 
Challenge to the Government’s ‘Rwanda Policy’, to transfer asylum claimants to Rwanda if they have arrived in the UK by making “dangerous journeys” arriving by “small boats”. The Claimants challenged the scheme on a number of grounds, including that Rwanda was not a “safe third country” based on evidence from the UNHCR, claimants risked being unlawfully returned by Rwanda to the country of their persecution (‘refoulement’), and contrary to the 1951 Refugee Convention. Raza acted for the Claimants ‘NSK’ and ‘AT’, who won their individual challenges to the Home Secretary’s decisions.

R (CSM) v Secretary of State v Secretary of State for the Home Department [2021] 4 WLR 110
First time in English law that a Court held the British State to be in breach of its ‘systems duty’ under Article 3 ECHR. The Court declared that the Home Secretary failed to: 1) put in place adequate systems of care to protect those with HIV detained under immigration powers; 2) take all reasonable steps to avoid a real and immediate risk of harm to the Claimant by timeously providing antiretroviral medication (material breach of Article 3 ECHR operational duty) – officials were not told about the need to administer antiretroviral medication without delay or how to obtain it 3) the Home Secretary had no or any adequate policies and guidance in place dealing with individuals with HIV and failed to prevent the failings in this case. Led by Chris Buttler KC.

R (Lawal) v Secretary of State for the Home Department (death in detention, SoS's duties) [2021] UKUT 114 (IAC)

It is the first domestic case to affirm that the duty to ensure an effective investigation under Article 2 ECHR affects the exercise of the Secretary of State’s immigration powers. The Court held that Home Secretary must not frustrate or undermine an inquiry into how and in what circumstances a vulnerable person died where Article 2 ECHR is engaged. Led by Sonali Naik KC.

Hemmati & Ors v Secretary of State for the Home Department [2019] UKSC 56
Led by Michael Fordham QC.
