Summary of Opinion

Factual and Procedural Background

The Appellant was born in The State on 30 December 1981. The Appellant's mother was born in The City and became a British Overseas Citizen under historical nationality legislation. The Appellant is a national of another State but has never resided there and continues to live in The State. The Appellant applied for registration as a British Overseas Citizen; the Respondent rejected the application by letter dated 5 June 2024. The Appellant sought judicial review, arguing that the statutory provisions relied on were unlawfully discriminatory on the basis of sex and incompatible with Article 14 read with Article 8 of the Convention. Lang J (Judge Lang) dismissed the claim for lack of jurisdiction on 4 February 2026. With permission, the Appellant appealed to the Court of Appeal. The appeal was heard on 1 July 2026 and determined on 22 July 2026.

Legal Issues Presented

1. Whether the Appellant is within the "jurisdiction" of the United Kingdom for the purposes of Article 1 of the European Convention on Human Rights, so as to enable a claim under Article 14 read with Article 8 challenging the Respondent's refusal to register her as a British Overseas Citizen.
2. Whether principles recognising extraterritorial jurisdiction (including those related to diplomatic/consular action or nationality-based links) extend to the circumstances of the Appellant's claim.

Arguments of the Parties

Appellant's Arguments

• Attorney Southey argued that, although jurisdiction is primarily territorial, the list of exceptional extraterritorial circumstances is not closed and international law principles (including analogies with consular/diplomatic jurisdiction) support recognising jurisdiction here.
• The Appellant contended that refusal to recognise nationality rights would leave her no forum to vindicate discrimination claims and that Convention rights should be interpreted to be practical and effective.
• The Appellant relied on the capacity of Article 1 rights to be "divided and tailored" (as in HF) and argued this could support jurisdiction in relation to Article 14 read with Article 8.

Respondent's Arguments

• Attorney Blundell submitted that the relevant authorities require an effective exercise of authority or control over the person or territory; mere capacity to take decisions affecting a person abroad or nationality-based links do not establish Article 1 jurisdiction.
• The Respondent argued the case law (including MN and Agostinho) shows that jurisdiction requires control over the person and that the present facts do not meet the threshold for extraterritorial jurisdiction.

Court's Reasoning and Analysis

The court began from the established principle that Article 1 jurisdiction is primarily territorial and is a threshold criterion (Al-Skeini). Extraterritorial jurisdiction arises only in exceptional circumstances and, where relevant, is governed by two main criteria: effective control over an area or State agent authority and control over individuals (Ukraine and the Netherlands v Russia; Agostinho; MN). The court emphasised that the requisite concept of control focuses on control over the person rather than over that person's interests, and that the mere taking, or capacity to take, decisions affecting a person abroad does not establish jurisdiction (Agostinho; MN).

The court considered the Appellant's reliance on diplomatic/consular analogies and on HF. It held that the present facts do not involve any exercise of authority or physical control by the United Kingdom over the Appellant, and therefore the diplomatic/consular authorities do not support establishing jurisdiction. HF was distinguished on the basis that Article 3(2) of Protocol No.4 has a particular subject-matter necessitating protection for nationals wishing to enter their State; that special character does not apply to Article 14 read with Article 8.

The court rejected the submission that recognising jurisdiction here would merely avoid inconsistency with another State's territorial rights; the case law requires an effective exercise of authority or control, not merely absence of conflict with other States. The court also held that procedural connections (such as bringing proceedings) do not create Article 1 jurisdiction for the purposes of Article 14/8 beyond their limited procedural effect (as in MN and HF). Applying these principles to the facts, the court concluded that the Appellant had never been within the UK's territory, had no private or family life in the UK, and that the Respondent had not purported to exercise authority or control over her; accordingly the jurisdictional threshold was not met.

Holding and Implications

DISMISSED

Holding: The Court of Appeal dismissed the appeal. The court held that the Appellant is not within the United Kingdom's jurisdiction for the purposes of Article 1 of the Convention in respect of her challenge to the refusal to register her as a British Overseas Citizen; therefore the claim under Article 14 in conjunction with Article 8 cannot be pursued in domestic courts.

Implications: The immediate consequence is that the Appellant's Convention claim cannot proceed in the United Kingdom. The court did not establish any new Convention law principle; it applied established Strasbourg and domestic authorities to confirm that nationality-based interests or legislative decisions affecting a person abroad do not, without more, give rise to Article 1 jurisdiction.
