UK age-assessment ruling: why relying on a local authority’s conclusion still requires scrutiny

The court examined the quality of reliance

In EXR v Secretary of State for the Home Department (No 3), [2026] EWHC 2527 (Admin), dated 16 October 2026, the High Court distinguished initial age decisions from later reliance on local-authority assessments. It found serious defects in the later decision-making and in the disclosure of relevant material during the litigation.

The published judgment concerns an age-disputed asylum claimant and proposed removals to France. The conclusion is not that every disputed age must be accepted or that the claimant was finally judicially declared to be a child. The central issue was whether the decisions challenged were lawfully supported by the assessment and evidence available.

A label does not replace examination of the evidence

The judgment addresses whether reliance on an assessment was reasonable under the Home Office’s Assessing Age policy and the required procedural standards commonly described as Merton compliance. A decision maker cannot resolve that question merely by noting that a local authority has supplied an age conclusion.

In this case, the treatment of a scanned birth certificate and the scope of a later review were material. A document does not become decisive simply because it purports to record birth, but relevant evidence still requires consideration. Where a review is asked to answer a narrow question while significant evidence falls outside its scope, its conclusion may not cure the original problem.

Build an evidence chronology rather than a document pile

For an age-disputed person, an organised chronology should identify each assessment, the evidence available at that time, any later correction and the decision that relied on it. Keep the original document, its source, translations and explanations of any inconsistency. The purpose is to make the evidential issue visible, not to conceal difficult facts.

If an earlier statement about age is disputed, address why it was made and why the later account should be accepted. A lawyer or representative needs the complete record, including adverse material. Repeating a preferred date of birth without explaining the evidential history may leave the decisive credibility question unanswered.

Candour and urgent removal decisions

The court also criticised failures of candour concerning internal records and correspondence. Judicial review depends on the public authority providing a fair account of material relevant to the challenge. An internal concern about compliance can matter even where the outward-facing decision simply states that an assessment was accepted.

The proceedings involved urgent attempts to prevent removal. Readers should not infer that raising an age dispute automatically suspends every removal. The procedural route, service of the decision and any interim order must be checked immediately. Our analysis of evidence in UK protection cases discusses the broader need to connect general material to individual facts.

What the judgment changes in practical preparation

• Identify the precise assessment on which the authority relied.
• Show whether material evidence was actually considered.
• Keep the instructions and scope of any reassessment or review.
• Check urgent remedies separately from the underlying age question.

The judgment reinforces the importance of an intelligible evidential process and accurate disclosure. It does not eliminate age assessment, grant immigration status or supply a universal answer for other claimants. Its value lies in showing how specific defects can undermine reliance on an assessment and the decisions built upon it.
