Judicial Clarification on Age Assessment in Immigration Cases: The Precedent of AI, R (On the Application Of) v West Berkshire Council

Introduction

The case of AI, R (On the Application Of) v West Berkshire Council ([2025] EWCA Civ 136) addresses a critical issue in immigration and asylum law – the assessment of a claimant’s age and its corresponding impact on the duties imposed on the local authority. In this case, the appellant, a Sudanese national who arrived in the United Kingdom in October 2021 seeking asylum, claimed that his true date of birth was 4 August 2004, arguing that he should have been treated as a child. Conversely, the Respondent, West Berkshire Council, based on an assessment and the Home Office’s administrative assignment, maintained that his date of birth was 20 April 1998, classifying him as an adult. This pivotal question not only influenced the provision of services and accommodation by the local authority but also had wider implications for the judicial review procedures applied in age-assessment cases.

At the heart of the dispute was whether the Upper Tribunal (Immigration and Asylum Chamber) provided adequate reasons for adopting the administrative age assessment. The Tribunal’s findings were challenged on the grounds that they did not sufficiently separate or explain the factual basis for determining the appellant’s age, thus impacting subsequent decisions made in connection with the Children Act 1989.

Summary of the Judgment

The Upper Tribunal Judge, after an extensive hearing, concluded that the appellant’s evidence was unreliable and that he had deliberately misrepresented facts concerning his age. The Tribunal rejected the appellant’s claim that he was a child at the relevant time by affirming the Home Office’s designation of his date of birth as 20 April 1998. In doing so, the Judge engaged in a thorough analysis of the appellant’s credibility, discrepancies in his testimony regarding schooling, language proficiency, and even social media activity. The Judge also acknowledged some valid criticisms of the Respondent’s age assessment process but ultimately determined that the evidence overwhelmingly supported the conclusion that the appellant was, in fact, an adult when he entered the UK.

In the appeal, the appellant’s sole argument was that the Tribunal had not provided sufficient reasoning for accepting the established date of birth. The Court of Appeal, however, upheld the Tribunal’s decision and found that, when read in full context, the reasoning was adequate. The judgment thereby dismissed the appeal, reinforcing that the determination of actual age in such binary disputes could be appropriately decided by the tribunal.

Analysis

Precedents Cited

The judgment is firmly rooted in a number of established precedents and earlier judicial decisions:

R (A) v London Borough of Croydon [2009] UKSC 8: This case established that determining whether a claimant is a child involves a jurisdictional fact, a determination that should be made independently by the court or tribunal. The Court in the present case reaffirmed that the tribunal’s function is not solely to challenge the evidence presented but also to establish, after a symmetrical inquiry, a precedent or “jurisdictional fact”.
MC v Liverpool City Council [2010] EWHC 2211 (Admin) and R (F and Ors) v London Borough of Lewisham [2009] EWHC 3542 (Admin): These decisions were cited to address the precise issue of determining a claimant’s actual age. Notably, the appellant argued that following these judgments, the tribunal should have provided discrete reasons for accepting the assigned date of birth. However, the court elucidated that the task of establishing whether the claimant was a child and, if so, his actual date of birth, are not always separate in practice.
Re V (A Child) (Inadequate reasons for findings of fact) [2015] EWCA Civ 274 and English v Emery Reimbold & Strick Ltd [2002] EWCA Civ 605: In these cases, the appellant emphasized the importance of judicial reasoning as a component of due process. The judgment referred to these decisions to establish that a concise explanation of the decision-making process is sufficient, so long as the parties can clearly understand the basis of the findings.

Legal Reasoning

The Court’s reasoning in this case was methodical and centered on the credibility of the appellant’s evidence. The pivotal aspects of the legal reasoning include:

Inquisitorial Approach: The Judge adopted an inquisitorial approach, meaning that rather than simply accepting the evidence at face value, he actively evaluated the credibility behind conflicting testimonies. This approach was consistent with judicial review principles in age-assessment cases.
Assessment of Credibility: A significant part of the tribunal’s analysis focused on discerning inconsistencies in the appellant’s narrative – discrepancies concerning his schooling, language proficiency, and even his utilization of social media. The habitual reliance on physical appearance and other corroborative factors underscored why the tribunal found the evidence unreliable.
Integration of Statutory Duties: Referencing the Children Act 1989 – specifically sections imposing duties on local authorities – the Judge clarified that the determination of whether the appellant was a child directly impacted the applicability of these statutory responsibilities. Consequently, the tribunal’s decision on the appellant’s age had tangible implications for both service provision and legal obligations.
Contextual Reading of Judgment: The Court emphasized that the reasoning provided in later paragraphs (107-110) should be read in conjunction with the earlier detailed analysis (paras 65-106), which set out the evidentiary grounds and the framework guiding the Tribunal’s decision. This holistic reading confirmed that the reasons given were sufficient and appropriately formulated.

Impact on Future Cases and the Relevant Area of Law

The decision in AI, R (On the Application Of) v West Berkshire Council is significant in several ways:

Clarification of Judicial Review Standards: The ruling helps clarify the standards required for judicial review in cases where factual determinations such as age are pivotal. It reinforces that a tribunal’s reasons, when read in context, may be deemed adequate even if they are brief.
Confirmation of Inquisitorial Function: The judgment underscores that in contexts where a fact (such as age) is deemed a jurisdictional matter, it is appropriate for the tribunal to adopt an inquisitorial role. This approach could influence how future tribunals conduct evidentiary assessments in immigration and asylum proceedings.
Policy in Age Assessment: By confirming the acceptability of relying on the evidence that supports an administrative date of birth notwithstanding some procedural criticism, the decision solidifies the legal framework under which local authorities exercise their statutory duties. This could serve as a precedent in ensuring that the complexities of determining a claimant’s age do not result in unwarranted reversals of administrative findings.

Complex Concepts Simplified

Some of the legal concepts and terminologies addressed in the judgment are intricate. Below is a simplification of these terms:

Jurisdictional Fact: This is a fact that the court or tribunal must determine independently because it has significant legal consequences (e.g., determining whether someone is a child, which affects rights and duties under the law). In this case, the tribunal’s determination of the appellant’s age was treated as such.
Inquisitorial vs. Adversarial Process: An inquisitorial process involves an active fact-finding role by the tribunal, as opposed to simply reviewing the decisions made by another body. This means the tribunal can, when evidence is disputed, undertake its own careful examination to arrive at a verdict.
Merton Compliance: While the term “Merton compliant” references an earlier case setting certain standards in facilitating fact-finding, here it suggests that the assessment process should adhere to established procedural and evidentiary norms—even if it falls short in some respects, this does not necessarily undermine the final determination.
Duty to Give Reasons: The obligation that judges and tribunals must provide clear explanations for their decisions. This duty ensures transparency, assists the losing party in understanding the outcome, and provides a solid ground for appeal if needed.

Conclusion

In summary, the Court of Appeal’s judgment in AI, R (On the Application Of) v West Berkshire Council reaffirms a robust judicial standard in the area of age assessment for immigration and asylum claims. The decision stands as a precedent for:

The appropriateness of a holistic, inquisitorial process for evaluating credibility in cases where a claimant’s age is of critical importance.
The sufficiency of concise yet contextually integrated reasoning for judicial decisions, even when relying on administrative findings.
The careful application of statutory duties under the Children Act 1989 in balancing the rights of the claimant with the responsibilities of local authorities.

This judgment not only clarifies the legal principles guiding age assessments but also sets a precedent that may shape future cases by emphasizing the importance of reasoned decision-making and evidentiary integrity in judicial reviews involving vulnerable individuals seeking asylum.

The case thereby contributes significantly to the evolving jurisprudence in immigration law, ensuring that while administrative procedures are respected, judicial oversight remains thorough, transparent, and fair.
