TW, R (on behalf of) v Essex County Council

Whether a child is a “child in need” under section 17(10) of the Children Act 1989 is an evaluative question for the local authority, subject to ordinary judicial review principles. The assessment is necessarily forward-looking. It must consider whether the child’s health or development is likely to meet the statutory standard without services under Part III.

The authority may consider support available from family members, other agencies and non-statutory early-help services. A child’s needs or vulnerabilities do not alone establish the statutory status. A rational professional assessment may conclude that those needs can be met without Part III services, even where another conclusion would also have been rational.

The appellant was aged 16 when his relationship with his stepfather broke down. He divided his time between his father’s and brother’s homes, sleeping on a sofa at each. A social worker identified unstable accommodation, mental-health difficulties and other vulnerabilities, but recommended accommodation through the Essex Young People’s Partnership and support from Family Solutions. The respondent decided that he was not a “child in need” under section 17 of the Children Act 1989.

Upper Tribunal Judge Ward, sitting as a High Court judge, granted permission but dismissed the judicial review claim: [2024] EWHC 264 (Admin). Following concessions and the abandonment of other grounds, the sole substantive issue on appeal was whether the judge had erred in concluding that the respondent’s assessment was not irrational. The Court also considered a last-minute application to add a new ground based on section 20(4).

1. Appeal dismissed. The conclusion that the respondent’s assessment was rational was unassailable. Whether a child is “in need” under section 17(10) of the Children Act 1989 involves evaluative judgments about reasonable standards of health and development, likely impairment and the services capable of meeting the child’s needs. Parliament entrusted those questions to the local authority, subject to fair process and Wednesbury reasonableness. There are no clear-cut right or wrong answers within those limits.

2. Section 17(10) is necessarily forward-looking because an assessment of what is likely or unlikely requires consideration of the future. The social worker’s assessment satisfied that requirement. It addressed the short-term inadequacy of the appellant’s sleeping arrangements, his longer-term housing needs, his emotional welfare and the support required in future.

3. The respondent rationally concluded that the appellant’s future needs could be met through accommodation arranged under the early-help scheme, additional Family Solutions support and assistance from his family, without services under Part III. The statutory distinction is between children whose needs exist and children whose needs will not be properly met without local-authority social services. It was permissible to consider support available outside Part III.

4. The circumstances could rationally have supported a finding that the appellant was a child in need. That did not make the contrary assessment irrational. The appellant had to establish that designation as a child in need was the only rational conclusion available, and he fell well short of doing so. Discussion of section 20 accommodation, a payment labelled “section 17 cash”, and the authority’s contractual role in arranging accommodation did not displace the clear assessment and decision.

5. The Court declined to import into section 17(10) the “real possibility” formulation used for the care-order threshold under section 31(2). Adding such a gloss to the clear statutory language would not assist social workers. The judge’s observation that the section 17(10)(a) test would not lightly be met did not impose an unlawfully elevated threshold.

6. The application to add a new section 20(4) ground was refused. It raised a substantial new issue without notice on the morning of the hearing, might have required evidence and would inevitably have caused an adjournment. Allowing such a fundamental late amendment would have been contrary to established appellate principles.

1. Court of Appeal (Civil Division): The appeal was dismissed: [2025] EWCA Civ 4 . The Court also refused permission to introduce a new ground based on section 20(4) of the Children Act 1989.
2. High Court, Administrative Court: Upper Tribunal Judge Ward, sitting as a High Court judge, granted permission on all grounds but dismissed the substantive judicial review claim: [2024] EWHC 264 (Admin) .
