R, R (on the application of) v London Borough of Croydon

Factual and Procedural Background

The Claimant, an asylum seeker from Afghanistan, challenges the Defendant local authority's determination that he is over 18 years old. The Claimant asserts he was born in the Afghan year 1372, corresponding to 21 March 1993 to 20 March 1994, making him about 17 years and 8 months old at the time of the hearing in June 2011. The Defendant assessed the Claimant as an adult over 18 years old in two age assessments carried out in May 2008 and December 2010.

The Claimant fled Afghanistan following the killing of his immediate family and lived in Iran before arriving in the UK in May 2008. He applied for asylum and was initially treated as a "Third Country" case, but this was later withdrawn and his asylum claim was considered and refused. The Claimant was referred to the Defendant for an age assessment, which concluded he was over 18 years old. The Claimant submitted an Afghan ID document (Tazkera) indicating he was 11 years old in 2004, supporting his claim to be under 18.

The Claimant was assessed by a paediatrician, Dr Birch, who provided three reports concluding that the Claimant's age was consistent with being a child aged approximately 15 to 17 years. The Defendant rejected these reports and relied on two age assessments by social workers concluding the Claimant was an adult. The Claimant brought judicial review proceedings challenging the Defendant's decisions. The case was stayed pending relevant Supreme Court and High Court decisions on age assessment methodology.

At the hearing, evidence was given by the Claimant, his legal caseworker, Dr Birch, and for the Defendant, the social worker assessor and Dr Stern, a consultant paediatrician. The Court considered the reliability of the differing assessments and evidence.

Legal Issues Presented

1. Whether the Defendant's age assessment concluding that the Claimant was over 18 years old was lawful and supported by evidence.
2. The proper approach to assessing age in cases of disputed age for unaccompanied asylum-seeking children, including the weight to be given to medical and social work evidence.
3. The reliability and scientific validity of the methodologies employed by expert paediatricians in estimating age based on physical, psychological, and developmental parameters.
4. The evidential weight to be accorded to identity documents issued abroad in age assessment proceedings.

Arguments of the Parties

Appellant's Arguments

• The Claimant relies on the Afghan ID document (Tazkera) indicating he was 11 years old in 2004, supporting a birth date between March 1993 and March 1994.
• Dr Birch’s expert reports concluded that the Claimant’s age was consistent with being between 15.1 and 17.1 years, based on a holistic assessment including psychometric testing, physical growth, and developmental parameters.
• The Claimant’s own account of his life chronology supports his claimed age, and the recent third assessment by Dr Birch corroborates earlier findings.
• The Claimant challenges the Defendant’s age assessments as flawed and contends that the benefit of the doubt should apply in cases of age uncertainty.

Respondent's Arguments

• The Defendant relies on two age assessments by social workers concluding that the Claimant is an adult aged 18 or over, based on physical appearance, demeanour, and interview evidence.
• The Defendant disputes the authenticity and reliability of the Afghan ID document, noting concerns about how it was obtained and the credibility of the Claimant’s uncle who provided the age on the document.
• Dr Stern, the Defendant’s paediatric expert, criticizes Dr Birch’s methodology as scientifically unproven and unreliable, highlighting the absence of blinded, peer-reviewed statistical studies validating her approach.
• The Defendant contends that the Claimant’s life chronology is vague and inconsistent, undermining the credibility of his claimed age.
• The Defendant emphasizes that the social workers’ holistic approach, without reliance on flawed statistical methods, provides a more reliable age assessment.

R (A) and (WK) v LB Croydon and Kent CC [2009] EWHC 939 (Admin)	Addresses the weight to be placed on paediatric evidence in age assessments.	The Court referenced this case to frame the evaluation of expert evidence on age.
R (B) v London Borough of Merton [2003] EWHC 1689 (Admin)	Sets out principles for local authority age assessments, including the necessity of holistic assessment, consideration of credibility, and adequate reasons for decisions.	The Court applied these principles to assess the Defendant’s age assessments and the procedural fairness of the process.
R(NA) v LB Croydon [2009] EWHC 2357 (Admin)	Considers the evidential status of Afghan identity documents in age assessment challenges.	The Court used this precedent to assess the credibility and weight to be given to the Claimant’s Afghan ID document.

Court's Reasoning and Analysis

The Court began by considering the Claimant's reliance on the Afghan ID document (Tazkera) and found significant concerns regarding its authenticity and accuracy. The document's provenance was questionable given the dangerous circumstances for the Claimant's uncle to obtain it, and the uncle's involvement in illicit activities undermined the reliability of the age stated therein. The Court thus placed little weight on the document.

The Court examined the Claimant's life chronology and found inconsistencies and vagueness in his accounts, diminishing the evidential support for his claimed age. Although the Court did not find deliberate deception, the imprecision in the chronology weakened the Claimant's case.

The Court gave detailed consideration to the expert evidence. Dr Birch's methodology involved psychometric testing, physical growth analysis, and statistical calculations purporting to estimate the Claimant's age. While acknowledging Dr Birch's extensive experience and expertise, the Court accepted Dr Stern's unchallenged criticisms that the statistical methods lacked scientific validation and peer-reviewed support, rendering them unreliable for precise age determination. The Court found that Dr Birch’s confidence in her statistical approach was misplaced and likely biased her conclusions.

The Defendant’s two age assessments by social workers were considered, with the Court preferring the second assessment due to the absence of cross-examination of the first assessor. The Court noted some inaccuracies and the limited training of the assessor but found the holistic approach, based on physical appearance, demeanour, and interview evidence, to be more reliable than Dr Birch’s flawed statistical method.

Ultimately, the Court concluded that the Claimant was more likely to be over 18 years old at the date of the second assessment (9 December 2010), corresponding to a birth date on or before that date, making him at least 18 years and 5 months old at the time of judgment.

Holding and Implications

The Court upheld the Defendant's age assessment that the Claimant was an adult aged 18 or over as of 9 December 2010.

The direct effect of this decision is that the Claimant is not entitled to the accommodation and support provisions under the Children Act 1989 applicable to children, nor to the extended duties owed to "former relevant children." The Court did not establish any new legal precedent but applied existing principles to the facts, emphasizing the necessity of reliable evidence and a holistic approach in age assessments. The decision underscores the Court's caution in relying on unvalidated statistical methodologies in expert age assessments.
