Din, R (On the Application of) v Secretary of State for the Home Department

Where entitlement to British citizenship depends on a disputed historical fact, the Administrative Court may determine that fact for itself on all evidence available at the hearing. This substitutionary function differs from ordinary supervisory judicial review and may require an enhanced level of scrutiny where necessary to secure a fair determination. The claimant bears the burden of proof, and the applicable standard is the balance of probabilities. Official records containing errors about date or place of birth may nevertheless support identity where their consistent recording of parentage, together with oral, documentary and DNA evidence, establishes the claimant’s identity on the balance of probabilities.

The claimant sought judicial review of decisions refusing to confirm that she was a British citizen. She claimed to be Yasmeen Din, born in Oxford on 26 June 1968 to Khair Din and Razia Begum. The Secretary of State relied on Pakistani records describing her as Yasmeen Sultana, born in Sahiwal on 4 January 1968.

The parties agreed that the Court had to determine the objective question of fact for itself, on the evidence before it, and that, if the claimant was born in Oxford as claimed, she acquired British citizenship by operation of statute. The central issue was whether the claimant had proved that identity and birth.

1. Substitutionary fact-finding. The Court was required to determine for itself whether the claimant was born in Oxford on 26 June 1968. This was not conventional supervisory judicial review of the Secretary of State’s assessment. The substitutionary function was supported by White & Collins [1939] 2 KB 838 and, in the human-rights context, by R (Harrison) v Secretary of State for the Home Department [2003] INLR 284.
2. The claimant bore the burden of proof under section 3(8) of the Immigration Act 1971. The standard was the balance of probabilities, in accordance with R (Begum) v Secretary of State for the Home Department [2014] EWHC 2968 (Admin).
3. The Court accepted the claimant’s identity evidence. The Pakistani records consistently identified her parents as Khair Din and Razia Begum, although they recorded an inaccurate date and place of birth. The Court considered that the parentage records were significant because they were not self-serving and no alternative parents were identified. It was inherently plausible, in the cultural and administrative circumstances, that the date and place of birth had been incorrectly recorded while the parentage remained accurate.
4. The finding was reinforced by the absence of any separate record of the Oxford-born Yasmeen, the claimant’s relationship to her siblings, the reliable evidence of Mohammed Yusuf, the claimant’s own evidence, and DNA evidence materially favouring full-sibling relationships. Difficulties concerning embassy visits, marriage records and the claimant’s applications for Pakistani and United Kingdom documents did not materially undermine her credibility.
5. The Court found that the claimant was born in Oxford on 26 June 1968 to Khair Din and Razia Begum. She was therefore a British citizen by operation of section 11(1) of the British Nationality Act 1981, read with the relevant provisions of the British Nationality Act 1948 and the Immigration Act 1971. The claim succeeded, and the parties were invited to submit an appropriate declaration and consequential submissions.
