I just skimmed the judgement to look at the issue of statelessness, as that's what I was discussing upthread. To clarify, she had Bangladeshi citizenship by descent up to her 21st birthday. So at the time the original order was made removing her UK citizenship she was not technically made stateless. However her argument is that she was made de facto stateless as she couldn't realistically exercise her Bangladeshi citizenship and it has in any case now expired.
Interesting wording of the legislation with its emphasis on the satisfaction of the Home Secretary and I can see how it could be argued either way. Did the order make her stateless, did the expiration of her Bangladeshi citizenship make her stateless, was it both, and does the legislation apply only in the present, or to future consequences if those consequences are predictable or perhaps even inevitable? We could discuss these points but in terms of the appeal it seems that the Home Secretary did take statelessness into account at the time which is all he needed to do.
Note that they wouldn't be able to make the same decision now. Funny that they could only remove her citizenship
because she was a minor. Couldn't do it now she's an adult.
Legislation
3. Section 40 of the BNA 1981 (“s 40”) provides, so far as relevant, as follows:
“(2) The Secretary of State may by order deprive a person of a
citizenship status if the Secretary of State is satisfied that
deprivation is conducive to the public good.
…
(4) The Secretary of State may not make an order under (2) if he
is satisfied that the order would make a person stateless.
