R (NG, AL and KM) v London Borough of Hillingdon  EWHC 2847 (Admin): claim challenging the failure to provide three unaccompanied asylum-seeking children in age-appropriate accommodation under ss.17 and 20 Children Act 1989. The local authority sought to argue that they did not “require” accommodation as there were adequate facilities in the hotel accommodation. Mrs Justice Lang DBE ruled that it was arguable that Hillingdon Borough Council were seeking to side-step their duties owed to the three children in what would be a “significant departure” from statutory guidance and case law.
R (BNB) v Kent County Council  EWHC 587(Admin): challenged the failure of two local authorities to provide the unaccompanied asylum-seeking child claimant with s.20 Children Act 1989 accommodation following the child’s dispersal to Napier Barracks. HHJ Walden-Smith ordered that Hillingdon Borough Council accommodate the claimant and held that they could not rely on their unlawful act that led to the dispersal.

R (The Motherhood Plan) v HM Treasury  EWHC 309 (Admin) (led by Jude Bunting with Clare Duffy) challenging the failure to exempt a self-employed woman’s maternity leave from the calculation of their self-employed support grant as discriminatory and unlawful on the grounds of pregnancy and sex under Article 14 and Article 1 Protocol 1 European Convention on Human Rights (ECHR) and in breach of the public sector equality duty under the Equality Act 2010.
R (Just for Kids Law) v Secretary of State for Justice (CO/4581/2020) challenging the lawfulness of the extension of the custody time limits, on the grounds that the failure to exclude children from the extension of custody time limits was unlawful and irrational; in breach of Article 5 and Article 14 ECHR as the Ministry of Justice acknowledged it would disproportionately impact black or ethnic minority children; breached the Public Sector Equality Duty; and, the duty to consult the Children’s Commissioner given the significant change of policy and its implication for prolonged deprivation of liberty in respect of children on remand. Following issue of the claim for judicial review, the Ministry of Justice agreed to introduce a new statutory instrument to exclude children from the extended custody time limit.
Donnchadh has also been instructed on behalf of NGOs in interventions in the Court of Appeal. He also advises in relation to related prison law and education law judicial reviews.
