Notable Cases

R (on the application of JW) v London Borough of Hackney CO/4215/2016 (Admin) – Eirwen represented the Claimant, a profoundly learning disabled young man, in respect of a claim for failures to carry out lawful needs assessments, carers assessments, and to make lawful eligibility decisions, pursuant to the local authority’s obligations under the Care Act 2014. The Claimant also challenged the lawfulness of the local authority’s policy for provision of residential respite care. The case settled after permission was granted on all grounds, with the local authority agreeing to suspend their residential respite care policy, to adopt a new policy following a lawful consultation process, and to pay the Claimant’s costs.

London Borough of Hackney v Williams and Anor [2017] EWCA Civ 26 – Eirwen was junior counsel for the Respondents in this case concerning local authorities’ obligations under s.20 of the Children Act 1989 and the extent to which failures to ensure parents give informed consent to the accommodation of their children can found a claim for Human Rights Act damages. Permission has been granted to appeal to the Supreme Court, where Eirwen continues to act as junior counsel.

RG v The High Commission for the Republic of Trinidad and Tobago (2200366/2016) – Eirwen represents the Claimant in this ongoing claim for unfair dismissal, breach of contract, failure to pay the National Minimum Wage and breaches of the Working Time Regulations against an embassy. The claim involves complex issues concerning state immunity and is currently stayed pending the decision of the Supreme Court in Benkharbouche v Secretary of State for Foreign and Commonwealth Affairs.

R (on the application of W) v London Borough of Hackney and London Borough of Redbridge CO/841/2016 (Admin) – Eirwen represented the Claimant, an 18 year old, in respect of her claim against the authorities for breaches of their obligations under Part III of the Children Act 1989 and Part VII of the Housing Act 1996. Interim relief in the form of accommodation and financial assistance was awarded to the Claimant following a contested hearing and permission for judicial review was granted. The matter settled with the First Defendant agreeing to pay damages for breach of Article 8 rights.

Holman v Devon County Council UKEAT/0127/15/BA – Eirwen represented the successful Appellant in an appeal concerning the employment tribunal’s failure to give adequate reasons for their decision and the correct construction of a contractual term. HHJ Hand QC allowed the appeal on both grounds.

Williams & Anor v London Borough of Hackney [2015] EWHC 2629 (QB) – Eirwen was junior counsel for the Claimants in this negligence and Human Rights Act claim against a local authority. The judge held that the local authority had failed in its obligations under Part III of the Children Act, breaching the Claimants’ Article 8 rights. He awarded £10,000 in damages to each Claimant.

R (on the application of M) v London Borough of Hackney [2014] EWHC 3470 (Admin) – While a caseworker at John Ford Solicitors, Eirwen was part of the team that acted for the successful Claimant. HHJ McKenna found that the local authority’s decision about appropriate care provision for a disabled child, EZM, had been “plainly irrational” as it failed to carry out carers’ assessments of EZM’s parents prior to any decision-making.
