An Upper Tribunal judge recently placed only limited weight placed on a local authority age assessment, and also provided guidance as to the reliability of social media evidence. Siân Davies sets out the key points from the ruling.

Age assessment “fact-finding” judgments (conducted in circumstances where a local authority has determined an applicant for services under the Children Act 1989 not to be a “child” and the age of the putative child is disputed) are by their nature fact-sensitive.

However, in the case of R(AY) v LB Barnet JR/5284/2019  Upper Tribunal Judge Kamara was able to place only “limited weight” on Barnet’s age assessment document, which is usually the core of a local authority case in such disputes, and the reasons why are instructive. She also gave useful guidance as to the production of social media evidence, to which she was also only able to attach limited weight because of deficiencies.

On the age assessment produced by Barnet, it was held that:

UTJ Kamara was also able to place only “limited weight” on social media posts which were relied upon by Barnet and again, her reasons for rejecting the relevance of these provide useful guidance as to what a Judge might expect, evidentially, in relation to social media posts [49,50].


Finally, it was held that Barnet had failed to consider Home Office records which were relevant to its findings on age, and country specific information (Barnet disputed the nationality of the Applicant, whereas the Home Office had accepted this) in reaching its conclusion on age [57].
