Ali, R (on the application of) v The Secretary of State for the Home Department & Anor

Factual and Procedural Background

This appeal concerns the Secretary of State for the Home Department's authority to detain unaccompanied children pending potential removal from the United Kingdom, focusing on the interpretation of Schedule 2 to the Immigration Act 1971 as amended by the Immigration Act 2014. The core question is whether detention is lawful when the detainee is initially reasonably assessed as an adult but later found to be a child under 18.

The claimant, a Sudanese national, entered the United Kingdom unaccompanied in July 2014, claiming asylum and initially stating an age of 17. However, the Home Office recorded his date of birth as over 18 and detained him. The claimant’s age was disputed, and the Home Office treated him as an adult due to his physical appearance and lack of credible evidence to the contrary, although he was not precluded from seeking a local authority age assessment.

After further enquiries, including recognition that Italy was responsible for his asylum claim, removal directions were issued but later cancelled following judicial review applications by the claimant, both refused. The claimant was released but detained again in February 2015. At that time, the Home Office reasonably believed him to be an adult. However, a Merton compliant age assessment conducted by a local authority shortly before this detention concluded he was a child aged approximately 16 or 17. Upon receipt of this assessment, the claimant was released in March 2015.

The High Court judge ruled that the detention from 17 February to 23 February 2015 was unlawful and awarded damages for wrongful detention. The Secretary of State was granted permission to appeal this decision.

Legal Issues Presented

1. Whether detention of a detainee, reasonably assessed at the time as an adult but later found to be a child under 18, is lawful under the amended provisions of Schedule 2 to the Immigration Act 1971.
2. The proper interpretation and application of paragraphs 16(2A) and 18B of Schedule 2 as amended by the Immigration Act 2014 in relation to detention of unaccompanied children.
3. The extent to which the duty under section 55 of the Borders, Citizenship and Immigration Act 2009 impacts the lawfulness of such detention.

Arguments of the Parties

Appellant's Arguments

• The appellant contended that detention was lawful if, at the time, reasonable grounds existed to suspect the detainee was an adult, relying on the wording "under paragraph 16(2)" to argue that paragraph 18B does not apply once such a reasonable assessment is made.
• It was argued that the amendments introduced by the 2014 Act did not intend to change the law established by the Supreme Court in R (AA) (Afghanistan) v Secretary of State for the Home Department, which held that detention based on reasonable but mistaken belief of adulthood was lawful and compliant with section 55 of the 2009 Act.
• The appellant emphasized practical difficulties and potential litigation arising from requiring objective proof of age before detention, describing such a requirement as "unrealistic".
• The appellant submitted that there was no clear parliamentary intention to introduce strict liability for detention of unaccompanied children and that the Explanatory Notes did not signal such a change.

Respondent's Arguments

• The respondent argued that the amended provisions of Schedule 2 clearly and unambiguously restrict detention of unaccompanied children to short-term holding facilities for a maximum of 24 hours, regardless of any reasonable belief about age at the time of detention.
• It was submitted that the definition of "unaccompanied child" in paragraph 18B(7) is objective and not qualified by reasonable grounds of suspicion or belief, thereby superseding the earlier Supreme Court decision in AA (Afghanistan).
• The respondent relied on the principle that statutory language must be given its ordinary and natural meaning and that the amendments were intended to strengthen safeguards for unaccompanied children in detention.
• Reference was made to the Supreme Court decision in R (A) v Croydon London Borough Council supporting the objective determination of age as a fact, and to established case law on unlawful detention principles.
• The respondent emphasized that the amendments promote the welfare of children and encourage careful age assessments by immigration officials.

Court's Reasoning and Analysis

The court undertook a detailed statutory interpretation of the amended provisions of Schedule 2 to the Immigration Act 1971, particularly paragraphs 16(2A) and 18B introduced by the 2014 Act. It concluded that these amendments impose clear and mandatory restrictions on the detention of unaccompanied children, limiting detention to short-term holding facilities for a maximum of 24 hours.

The court rejected the argument that reasonable grounds to suspect adulthood at the time of detention suffice to render detention lawful if the detainee is in fact a child. The statutory language uses the present tense "is" an unaccompanied child, without qualification by reasonable suspicion, thereby imposing strict liability for unlawful detention beyond the permitted limits.

The court acknowledged the earlier Supreme Court decision in AA (Afghanistan) but held that the legislative amendments effectively supersede that precedent, creating a new legal framework with stronger protections for children.

The appellant’s interpretation was deemed artificial and strained, amounting to rewriting the statute to insert words not present in the text. The court emphasized that the intention of Parliament must be derived from the actual statutory language, not presumed intentions or policy considerations.

While recognizing practical difficulties and potential increased litigation, the court held that these do not justify ignoring the clear statutory wording. The amendments promote the welfare of children and encourage careful and cautious age assessments by immigration officials, consistent with the duty under section 55 of the Borders, Citizenship and Immigration Act 2009.

The court also considered relevant case law on objective determination of age and unlawful detention, finding that none undermined the conclusion that the amended Schedule 2 provisions must be given effect as written.

Holding and Implications

The court DISMISSED the appeal, affirming the High Court’s decision that detention of the claimant from 17 February to 23 February 2015 was unlawful under the amended provisions of Schedule 2 to the Immigration Act 1971.

The direct consequence is that the Secretary of State remains liable for damages arising from the wrongful detention during that period. No broader new precedent was established beyond confirming the effect of the 2014 legislative amendments, which impose strict limits on detention of unaccompanied children regardless of reasonable belief at the time of detention.
