“… the power to refuse admission under this section shall not be exercised … in the case of a Commonwealth citizen who satisfies an immigration officer … - (a) that he wishes to enter the United Kingdom for the purposes of employment there, and is the person described in a current voucher issued for the purposes of this section by or on behalf of the Minister of Labour …”
“Where a person acquired [British] citizenship … by the operation of a law which applied to him because of his registration … under an enactment having effect before commencement, the Secretary of State may by order deprive the person of the citizenship … if the Secretary of State is satisfied that the registration … was obtained by means of – (a) fraud, (b) false representation, or (c) concealment of a material fact.”
“before the provisions of section 20 … can be prayed in aid, in my judgment the appellant must show that he can bring himself within subsection (1) of that section. He seeks to do so by reliance upon the fact of registration as evidenced by the certificate. If it were clear that the appellant was the Javed Iqbal originally named and identified in the Pakistani passport and in the other relevant documents and that the Secretary of State had intended to grant registration to that person, this argument would clearly have great force because it would be to that person so named and identified that that grant would have been directed. But the evidence is that that person was dead. The Secretary of State’s intention cannot have been to grant registration to the appellant for he did not know who the appellant was. He wrongly believed the appellant to be Javed Iqbal, which he was not, nor could have been, for that individual was dead. There are, I think, only three possible effects of the purported registration. First, it was a grant to Javed Iqbal. Secondly, it was a grant to the appellant. Thirdly, it was a grant to nobody but was a nullity. I have given my reasons already for rejecting the first two possibilities. There remains the third, that the purported grant was a nullity … I accept that in some cases it may be difficult to draw a dividing line in these cases between a registration which is a nullity and therefore void, as I think is the case with the present registration, in which case the alleged citizen by registration cannot bring himself within section 20(1) at all, and a registration which is only voidable, in which case the machinery of section 20 … has to be invoked … [Counsel for the Secretary of State] accepted that it was not easy to formulate a dividing line between the two classes of case. I agree, but wherever that line is drawn, I am clearly of the view that the instant case is one in which the alleged British registration was a nullity.”
“It seems to me that the only question to be decided is whether the appellant ever was a citizen of the United Kingdom by registration. I find it difficult to see how he could be. He chose to assume the identity of a dead man, he took the oath of allegiance and filled in the necessary forms in the dead man’s name. I find it impossible to say that in those circumstances Sultan Mahmood became a citizen of the United Kingdom any more than did Javed Iqbal. The proceedings were ineffective and section 20 never applied.”
“The applicant relies on the registration effected on the application of Waris Ali. In my judgment, that registration does not prove that the applicant is a citizen of the United Kingdom and Colonies by registration. When Waris Ali applied for the registration he undoubtedly intended to procure the registration of the applicant and nobody else. But the effect of the registration cannot depend on the intention of the applicant, Waris Ali. The registration which was in fact effected was the registration of Parvaz Akhtar, son of Waris Ali. This registration applies to the applicant and is conclusive of the claim of the applicant to be patrial if, but only if, the applicant is Parvaz Akhtar, son of Waris Ali. But the applicant has not proved that he is the person registered.”
“[The] provisions [of s.40], of course, only apply to the person described in the registration or certificate of naturalisation. If he is not, as in … Parvaz Akhtar … and … Sultan Mahmood …, then the registration or certificate confers nothing on that person.”
“It is hereby declared that, except as otherwise provided in this Act, a person is not to be treated for the purposes of any provision of this Act as ordinarily resident in the United Kingdom … at a time when he is there in breach of the immigration laws.”
