Begum v Secretary of State for the Home Department

JUSTICE has been granted permission to intervene by written submissions in the UK Supreme Court appeal in the case of Begum. The Court is considering whether (1) a fair and effective appeal can take place without Begum being granted leave to enter the UK to take part in the substantive Special Immigration Appeals Commission (SIAC) appeal; and (2) whether SIAC should have considered the possibility of violation of articles 2 and 3 ECHR (a policy consideration of the Secretary of State in determining whether to remove citizenship) as a judicial review or on the merits.

Shamima Begum left the UK at the age of 15 with two school friends and travelled to Syria and married an ISIL fighter. She had three children, who all died as infants. She is currently detained in the Al-Roj camp run by the Syrian Democratic Forces, where conditions are very poor. Ms Begum wishes to return to the UK but in February 2019 the Secretary of State deprived her of British citizenship due to the assessed risk to national security and refused her leave to enter the UK to challenge that decision.

JUSTICE’s intervention focusses on the origins of citizenship in the ancient common law of allegiance and its duty of protection, and the extent to which the Executive may frustrate that law without affording the longstanding principles of natural justice, including the protection of the laws of the State, access to the courts and the right to fair, meaningful and effective participation.

The UK Supreme Court will hear the cross appeals on 23rd and 24th November. We are being represented pro bono by Felicity Gerry QC and Eamonn Kelly.
