KV, R (on the application of) v Secretary of State for the Home Department

On an appeal against deprivation of citizenship obtained by fraud, the tribunal conducts a full reconsideration rather than judicial review. Once fraud is established, it must evaluate whether deprivation is right, balancing the public interest against foreseeable consequences.

Potential statelessness does not bar deprivation under section 40(3) of the British Nationality Act 1981. It is nevertheless a material consideration, particularly where former nationality cannot realistically be resumed. The person relying on such additional consequences bears the burden of proving them.

Foreign law is a question of fact, but expert evidence is not invariably required. A court or tribunal may accept reliable and comprehensible legal materials, having regard to the nature of the issue, the legal system, the sources and proportionality of cost.

The appellant had obtained British citizenship after concealing that he had previously secured citizenship in a false identity. The Secretary of State decided to deprive him of citizenship under section 40(3) of the British Nationality Act 1981.

The First-tier Tribunal dismissed his appeal without deciding whether deprivation would make him stateless. The Upper Tribunal accepted that omission as an error of law but held it immaterial because the appellant bore, and had not discharged, the burden of proving statelessness.

The appellant appealed to the Court of Appeal. The central issues were who bore that burden; whether the existing evidence established statelessness and an inability to resume Sri Lankan citizenship; and how those consequences affected the statutory discretion.

1. Appeal allowed and case remitted. The Upper Tribunal correctly held that a person deprived of citizenship obtained by fraud bears the burden of proving any particular adverse consequences relied upon, including statelessness. Unlike section 40(2), section 40(3) of the British Nationality Act 1981 contains no condition precedent prohibiting deprivation where statelessness would result.

2. An appeal under section 40A is a full reconsideration of whether citizenship should be withdrawn. It is an extension of the administrative decision-making process, not judicial review of the Secretary of State's decision. Once the statutory condition precedent is established, the tribunal must decide whether deprivation is right after determining its reasonably foreseeable consequences. The Secretary of State's assessment and published policy ordinarily merit considerable weight.

3. Even where article 8 of the Convention is not engaged, the decision requires evaluation of the competing interests. A formal four-stage proportionality test is unnecessary, but the decision-maker must balance the public interest against the consequences for the individual and others. Statelessness is especially material where naturalisation caused the loss of a former nationality which cannot be resumed, because deprivation then places the person in a worse position than if naturalisation had never occurred.

4. A stateless person is someone whom no state considers a national under the operation of its law. Proof ordinarily need address only states with which the person has a relevant connection. The Sri Lankan legislation established that the appellant had lost Sri Lankan citizenship upon becoming British and would not regain it automatically. Resumption required residence in Sri Lanka and a ministerial declaration. He therefore would become stateless and had neither a present right nor a realistic prospect of resuming Sri Lankan citizenship.

5. Foreign law is treated as fact, but expert evidence is not invariably indispensable. The court or tribunal may assess whether reliable legal materials can safely be interpreted without an expert, considering the question, the foreign legal system, the sources and proportionate cost. The Upper Tribunal was entitled to consider the amended statutory text.

6. The Upper Tribunal's error was material because it failed to evaluate whether deprivation remained justified in light of the established consequences. The matter was remitted for that determination. The expert report tendered on appeal was admitted only to confirm the current wording of Sri Lankan legislation; the remaining fresh evidence was refused.

1. Court of Appeal (Civil Division): Allowed the appeal and remitted the case to the Upper Tribunal to reconsider the section 40(3) discretion in light of the appellant's statelessness and inability to resume Sri Lankan citizenship.
2. Upper Tribunal (Immigration and Asylum Chamber): On 9 March 2016, dismissed the appeal. It accepted that the First-tier Tribunal had erred by omitting statelessness but considered the error immaterial because the appellant had not proved it.
3. First-tier Tribunal (Immigration and Asylum Chamber): On 16 September 2015, dismissed the appeal against deprivation of citizenship. It found that naturalisation had been obtained through fraud, false representation or concealment, but did not determine statelessness.
