Notable Public Law Cases


Derby City Council v R (UYR) [2025] EWCA Civ 1648

Represented the Respondent, a putative child, in this appeal which dealt with complex issues relating to interim relief in judicial review age assessment claims. The case considers the correct test which the first instance Courts should apply when considering the relevance of the strength of the Claimant’s case as part of considering whether to grant interim relief requiring a local authority to treat the Claimant as a minor pending the outcome of a claim. David successfully argued that a lower threshold test should be applied. The case also considers the correct Defendant where multiple local authorities have been involved in the Claimant’s case. David led Susana Ferrin in the appeal.

R (Abuali) v Cardiff City Council (AC-2025-CDF-000045)

Represented the Claimant before the Administrative Court in Wales. The claim challenges the local authority’s decision to refuse a ‘management discretion let’, which allows the local authority to allocate housing outside of its allocation scheme. The claim is brought on two grounds. Firstly, the failure of the local authority to properly apply its policy (a statutory requirement in this case, but also a duty in common law). Secondly, breach of the public sector equality duty (“PSED”), per s.149 Equality Act 2010. This includes discrete determination of Welsh legal issues on the impact of The Equality Act 2010 (Statutory Duties) (Wales) Regulations 2011, which informs adherence to the PSED in Wales. Permission was granted and the claim settled with the local authority providing suitable accommodation, agreeing to undertake an Equality Impact Assessment of its allocation scheme, and agreeing to update its scheme.

R (AI) v West Berkshire Council [2025] EWCA Civ 136

Represented the Appellant in the Court of Appeal in a case which challenged the lawfulness of the reasons given by an Upper Tribunal (IAC) Judge when determining the Appellant’s date of birth.

R (SG) v Devon County Council [2025] EWHC 96 (Admin)

Represented the interested party NHS Trust in this case where the Claimants challenged the decision of the Defendant local authority to close down drop-in centre services in North Devon. The case raised issues of duties the Care Act 2014 (and other statutory considerations) of public bodies when considering whether to end a service and, further, issues of Wednesbury unreasonableness. The NHS Trust was directly involved as whilst the decision to run or close the services was that of the local authority, the NHS Trust managed and ran the service on a day-to-day basis by way of an agreement under s.75 of the Care Act 2014.


R (Draper) v Secretary of State for Justice [2024] EWHC 1892 (Admin)

R (DXK) v Secretary of State for the Home Department [2024] EWHC 579 (Admin); [2024] 4 W.L.R. 46

Represented the Claimant in this case challenging the adequacy of the accommodation which is provided to pregnant/new mother asylum seekers (“PNMAS”). It was the lead case challenging the Secretary of State’s policy and system of allocation and provision of accommodation provision for pregnant / new mother asylum seekers. The Court held that the Defendant’s system of allocation was unlawful because the Defendant failed to monitor or collect data on the numbers of PNMAS in the asylum estate, which was a breach of the public sector equality duty under s.149 of the Equality Act 2010. The Court also made a number of observations on the flaws in the Defendant’s system. David represented the Claimant (and a large number of Claimants in linked claims) in the interim relief and permission stages of the claim and was led by Philip Rule KC for the substantive hearing.


R (RLQ) v Welsh Ministers (AC-2023- CDF-000107)

Represented the Claimants in this case which challenges the decision of the Welsh Ministers to end holiday free school meal funding in Wales. The case raises a number of untested issues, including the duties of the Welsh Government to comply with and have due regard to their duties under the Rights of Children and Young Persons (Wales) Measure 2011, s.149 Equality Act 2010 (public sector equality duty), and to consult relevant persons under The Equality Act 2010 (Statutory Duties) (Wales) Regulations 2011 and common law. The Welsh Ministers conceded the case without a hearing and declarations were made that their decision making process was unlawful. David was led by Gwion Lewis KC.

R (SA) v Secretary of State for the Home Department [2023] A.C.D. 101; [2023] EWHC 1787 (Admin)

Represented the Claimant in an important case where Mr Justice Fordham gave guidance on when hotel accommodation being provided for asylum seekers under s.95 of the Immigration and Asylum Act 1999 becomes ‘inadequate’, and thus unlawful. The case focuses in particular on the use of such accommodation for pregnant women and families with young children. The Court held that in the circumstances of the case, the Defendant requiring a pregnant woman, her 3 children, and latterly her baby, to reside in a hotel room for 15 months was unlawful.


R (AF) v Milton Keynes Council [2023] A.C.D. 46; [2023] EWHC 163 (Admin)

Represented the Claimant in this case challenging the refusal of the Defendant to undertake an age assessment of the Claimant or properly consider its duty to do so. The case considered public bodies’ duties of enquiry (Tameside duties), procedural fairness, and unreasonableness.


Marland v Director of Public Prosecutions [2023] 2 Cr. App. R. 5; [2023] EWHC 1046 (Admin)

R (RJ) v Devon County Council [2023] EWHC 961 (Admin)

Represented the Claimant in the Administrative Court challenging the failure of the Defendant to provide suitable education for the 11-year-old claimant under s.19 of the Education Act 1996 and to make educational provision for him in accordance with his Education, Health and Care Plan (EHCP), in breach of s.42 of the Children and Families Act 2014. The Court allowed the claim at a substantive hearing (unopposed at the door of the Court) and made declarations and mandatory orders that suitable education be provided.


R (Russell) v Hywell Dda University Health Board (CO/1421/2022)

Represented the Claimant. The claim concluded with the Administrative Court approving an order allowing the Claimant’s application for judicial review on the basis that the Health Board had unlawfully failed to support her to access the wider community in breach of duties under the Social Services Well-being (Wales) Act 2014 and Care and Support (Eligibility) (Wales) Regulations 2015. The Court also ordered the Health Board to take steps to support the Claimant and facilitate such access to the wider community.


R (Rai) v Winchester Crown Court [2021] Crim LR 795; [2021] EWCA Civ 604

Represented the Claimant in the Court of Appeal in this claim challenging the decision of a Crown Court Judge to allow the press to report the home address of a vulnerable woman charged with murder and infanticide. The case considered the competing principles of freedom of the press (article 10 ECHR) and the right to privacy (article 8 ECHR). Led by Philip Rule.


R (Rose) v Welsh Ministers & Others (CO/1484/2020)

Represented the Welsh Government in a judicial review in which the Claimant sought to establish the legal definition of ‘open air-recreation’ and whether caving falls within that definition. The claim involved a number of technical legal questions, including whether the decision the Claimant wished to challenge was justiciable, whether the claim was academic as it invited consideration of hypothetical points of law which did not arise out of the decision challenged, and finally, detailed consideration of the interpretation of the provisions of the Countryside and Rights of Way Act 2000. The claim concluded with a negotiated settlement.


R (Delaney) v The Parole Board of England and Wales [2019] EWHC 779 (Admin)

Notable Court of Protection Cases


Bristol City Council v LME [2025]

Represented P in this s.16 MCA 2005 application where P presents with bi-polar and an acquired brain injury. She has substantial funds arrived at by way of a personal injury claim and can fund care and support to support her to reside in her own flat in the community. However, she objected to those care and support arrangements, despite presenting with risk taking behaviours. She had been assessed as having capacity to engage in sexual relations but not to make decisions relating to persons with whom she should have contact, requiring a TZ care plan. The case also involved a history of the local authority failing to put in place any lawful deprivation of liberty arrangements whilst she resided at a supported living placement prior to her community placement and as a result included a substantial damages claim within the COP proceedings and a settlement of £70,000 for LME.


RC v Gloucestershire County Council [2025]

Represented the protected party in this challenge under s.21A MCA 2005. The case concluded in a 2 day contested hearing considering RC’s capacity to conduct proceedings and make decisions relating to his residence and care. After cross examination of a consultant psychiatrist, social worker, and DOLS assessor the Court concluded that RC had capacity and terminated the standard authorisation.


Rhondda Cynon Taff CBC v AA [2025]

Represented the son of P in a complex case in this s.16 MCA 2005 application with difficult family dynamics where P’s son was serving a long-term prison sentence and wanted contact with his mother, who was experiencing dementia, but where P’s husband did not wish to assist in facilitating such contact.


JR v South Gloucestershire Council [2025]

Represented P in this case under s.21A MCA 2005 where P objects to her placement in a care home and expresses a wish to return to living with her husband. The case involved complex and sensitive dynamics as P had lived with her husband for 60 years, but before she had been determined to lack capacity to make decisions relating to her residence and care, she had chosen to leave the family home and safeguarding referrals had been made to the local authority. P’s husband was also a party to proceedings.


Cornwall Council v HW (by her litigation friend the Official Solicitor), A NHS Trust, and An Integrated Care Board [2025]

P resides in a bespoke single person placement with 24-hour care and support.

A Local Authority v SF (by his litigation friend the Official Solicitor), A NHS Trust, and AF [2024]

Represented the protected party in this s.16 MCA 2005 application where the local authority sought to approve P’s DOL in a supported living placement. The case raised complex issues due to P’s young age (23) and complex diagnosis and presentation. He required extensive support, which required a robust care and support team around him to live in a supported living environment. The case also raised issues as to how the COP can take action to ensure P receives proper educational provision in line with an education and healthcare plan (EHCP).

A Local Authority v HW (by her litigation friend the Official Solicitor) and A NHS Trust [2024]

Represented the local authority in this s.16 MCA 2005 application for a community DOLS where P is a young woman (aged 18) with developmental language disorder and cognitive impairment. She experiences significant anxiety, low mood, and emotional dysregulation and is in need of regular support to prevent and address challenging and aggressive behaviours and self-harm.

Represented the protected party, a young lady with autism spectrum disorder, a learning disability, and attachment disorder resulting in complex care and support needs. P was provided with residence at care in a flat in a hospital setting, but the professionals disagreed as to whether she required a hospital setting, raising legal issues relating to the proper framework for P’s deprivation of liberty (the Mental Capacity Act 2005, the Mental Health Act 1983, or the Inherent Jurisdiction of the High Court). The Court sat dual-ticked in the COP and High Court to determine the point. Further issues arose as to P’s best interests and how care and support was best provided, including whether it should be provided in the community in a flat with or without her mother, BJ.


MAW (by her Litigation Friend the Official Solicitor) v A Local Authority [2023]

Represented the protected party in this case where the local authority planned to move P from her residential care home to a supported living flat in a care home against her wishes and feelings.

Represented the protected party, a young lady with autism spectrum disorder, a learning disability, and attachment disorder resulting in complex care and support needs. P was provided with residence at care in a flat in a hospital setting, but the professionals disagreed as to whether she required a hospital setting, raising legal issues relating to the proper framework for P’s deprivation of liberty (the Mental Capacity Act 2005, the Mental Health Act1983, or the Inherent Jurisdiction of the High Court). The Court sat dual-ticked in the COP and High Court to determine the point. Further issues arose as to P’s best interests and how care and support was best provided,
including whether it should be provided in the community in a flat with or without her mother, BJ.


COT v A Local Authority, MB, and POT (by her litigation friend, the Official Solicitor) [2023]

Represented the protected party in this case where P was residing in a care home, in line with her wishes and feelings, but her daughter had made an application under s.16 MCA 2005 for an order that P moved to reside with her. Safeguarding issues had been raised and the applicant daughter had previously removed P from the care home without Court consent. The applicant was unrepresented. P’s other daughter was also an unrepresented party who opposed a move. After a 2-day hearing, the Court determined that it was in P’s best
interests to remain in the care home and a negotiated settlement on contact arrangements was approved by the Court.


SC v A Local Authority and KC [2023]

Represented the local authority in this case where P was diagnosed with a Schizoid Personality Disorder and communication difficulties and cognitive impairment further to a stroke. Complex capacity issues arose relating to ability to communicate a decision (which required SALT and rehabilitation OT involvement) and unwise decision making, as P had always resided in a shed on his family’s land and wished to return. Issues of best interests arose and available options in the context of planning law as P’s shed had not been granted planning permission, but was exempt from planning permission as he had used it as a residence for over 10 years.


JM v A Local Authority and An NHS Trust [2022]

Represented the local authority in this case where P had been admitted to hospital after neglect whilst living with her son and expressed a wish to be discharged to live in Scotland. P was also adamant that she did not want to be discharged to a care home in the interim. Complex issues arose regarding care and support and deprivation of liberty when moving Scotland and required consideration of issues of habitual residence (relevant to the applicable law, England and Wales or Scotland) and both sch.3 of the MCA 2005 and the Adults with Incapacity (Scotland) Act 2000. Case further complicated by P’s representatives and the local authority considering interim discharge from hospital would not be in P’s best interests and the Trust taking a different position.


Re: JW [2021]

Represented the Office of the Public Guardian in this case where the OPG applied for orders removing family members as attorneys on the basis that they transferred large sums of money from P’s estate and had improperly used P’s funds for gifts. The OPG also applied for the appointment of a professional deputy to manage P’s property and affairs, which was determined at a contested hearing.


A Local Authority v JL and EL [2020]

Represented the local authority in the Family Division of the High Court exercising its inherent jurisdiction. The protected party was a disabled young woman who had been assessed as having capacity within the terms of the Mental Capacity Act 2005 to make decisions as to her residence, but being incapacitated and thus unable to make such decisions by way of the coercive, abusive relationship with her
partner, who also had mental health difficulties. The case also involved an application for an injunction against the vulnerable person’s partner.
