Administrative and Public Law

Overview

Nadia’s judicial review work cuts across her multi-disciplinary practice, drawing on her strong academic and policy background, teaching administrative law at UCL and working with organisations, including Liberty and JUSTICE. She accepts judicial review instructions in all areas of immigration law, unlawful detention, community care and education law. She regularly acts, led and unled, in complex claims concerning the interplay between these areas.

Notable Cases

BLZ No 1 (R (BLZ) v Secretary of State for the Home Department [2025] EWHC 153 (Admin)): Nadia acted for the successful Claimant in this landmark case in which Fordham J held that the Home Office systemically failed to provide safe and suitable accommodation to disabled applicants on release from immigration detention (led by Stephanie Harrison KC, with Grace Capel and Isaac Ricca-Richardson).

BLZ No 2 (R (BLZ) v Leeds City Council [2025] EWHC 154 (Admin)): Nadia acted for the Claimant in this case in the first published authority on the interplay between the Care Act 2014 and Schedule 10(9) Immigration Act 2016. The High Court held that Home Office bail accommodation under Schedule 10(9) IA 2016 is ‘residual’ and ‘legally irrelevant’ to the Care Act 2014.

R (CWJ) v Director of Legal Aid Casework & Lord Chancellor [2025] EWHC 306 (Admin): Nadia acted for MIND (the mental health charity) in an intervention highlighting the impact on children’s mental health of permanent exclusion (led by Grace Brown). The High Court recognised for the first time that the right to a fair hearing under Article 6 ECHR can be engaged in school exclusion appeals before an Independent Review Panel (‘IRP’), opening the possibility of legal aid being granted for such appeals moving forward.

R ((RWU) by his litigation friend LTA) v The Governing Body of A Academy [2025] EWCA Civ 147: Nadia acted for the intervener, Black Equity Organisation (‘BEO’), in this rolled-up hearing before the Court of Appeal, a case concerning the interplay between permanent exclusion from school and the positive obligation to protect victims of trafficking/ modern slavery under Article 4 ECHR (led by Duran Seddon KC).

R v IA (see here): Nadia successfully acted for an age disputed unaccompanied asylum-seeking child in these unusual proceedings before the Youth Court, in which the District Judge treated the question of IA’s age as a preliminary issue (led by Stephanie Harrison KC with Gráinne Mellon).

R (AK) v Westminster City Council [2024] EWHC 769 (Admin): Nadia acted for the Claimant in this successful judicial review challenging the lawfulness of Westminster City Council’s Housing Allocation Scheme. The High Court held that the scheme indirectly discriminates against women and girls who need to move borough to escape violence, and that Westminster had breached the Public Sector Equality Duty (‘PSED’) (led by Stephanie Harrison KC).

R (Wendy Smith) v Secretary of State for the Home Department [2024] EWHC 1137 (Admin): Nadia acted for Friends, Families and Travellers in an intervention in this landmark claim for judicial review, in which the High Court held that certain provisions of the Criminal Justice and Public Order Act 1994, introduced by the Police, Crime, Sentencing and Courts Act 2022, are incompatible with Article 14 ECHR (the prohibition on discrimination) read with Article 8 ECHR (the right to private life) as they amount to unjustified discrimination against Gypsies and Travellers (led by Stephen Simblet KC).

R (TMX) v London Borough of Croydon [2024] EWHC 129 (Admin): Nadia acted for the successful Claimant in this important judicial review claim about the interplay between local authority duties under the Care Act 2014 and Home Office duties under s. 95 Immigration Act 1999. The High Court held that in failing to provide the Claimant with suitable accommodation, Croydon had breached his Convention rights under Articles 3 and 8 ECHR.
