Key cases

WAS (Pakistan) v SSHD [2023] EWCA Civ 894
Successfully appeared (led by Eric Fripp) in an international protection case where Court of Appeal made further observations regarding the evidential limits that may constrain Appellants who claim that surveillance of their sur place activities by the hostile state has taken place.

Major v Kirishana [2023] EWHC 1593 (KB)
Successful appeal against an interlocutory decision which had refused a litigation friend’s application to be discharged on grounds of poor mental health and withdrawal of consent to act. High Court set new test for an application to discharge litigation friend, largely adopting appellant’s submissions.

SI (2023)
Permission granted in JR of local authority’s failure to conduct a lawful child in need assessment where an age-disputed asylum seeker was referred to them for assessment and support. The local authority purported to accept the claimed date of birth of the claimant when assessing him, finding he was under-age, but returned him to adult accommodation without further support or assistance given the proximity of his (claimed) 18th birthday. Lengthy extension of time for bringing JR was granted and the matter ultimately settled.

R (LYB) v Kent CC [2021] EWHC 663 (Admin)
Permission granted in decision which affirmed the lower threshold for permission decisions in age assessment cases, and found that in an application for interim relief to have the claimant accommodated as a child pending determination of the JR, the balance of convenience was ‘clearly’ in favour of the grant of interim relief, following the reasoning of Fordham KC in R (BG) v Oxfordshire County Council [2014] EWHC 3187 (Admin)

Tekocak [2021] EWCA Crim 724
Appeared (without lead counsel) in Court of Appeal.
