“(5) A person who is not a British citizen is liable to deportation from the United Kingdom if – (a) the Secretary of State deems his deportation to be conducive to the public good; or (b) another person to whose family he belongs is or has been ordered to be deported. (6) Without prejudice to the operation of subsection (5) above, a person who is not a British citizen shall also be liable to deportation from the United Kingdom if, after he has attained the age of seventeen, he is convicted of an offence for which he is punishable with imprisonment and on his conviction is recommended for deportation by a court empowered by this Act to do so.”
“364. Subject to paragraph 380, while each case will be considered on its merits, where a person is liable to deportation the presumption shall be that the public interest requires deportation. The Secretary of State will consider all relevant factors in considering whether the presumption is outweighed in any particular case, although it will only be in exceptional circumstances that the public interest in deportation will be outweighed in a case where it would not be contrary to the Human Rights Convention and the Convention and Protocol relating to the Status of Refugees to deport. The aim is an exercise of the power of deportation which is consistent and fair as between one person and another, although one case will rarely be identical with another in all material respects. … .”
“8. The 1971 Act contemplates first a decision by the Secretary of State to make a deportation order under section 3(5) of that Act, in the present case in respect of a person who is not a British citizen “(b) if the Secretary of State deems his deportation to be conducive to the public good”
“10. Section 4(1) of the [Special Immigration Appeals Commission Act 1997 (the 1997 Act)] provides that the Commission: “(a) shall allow the appeal if it considers— (i) that the decision or action against which the appeal is brought was not in accordance with the law or with any immigration rules applicable to the case, or (ii) where the decision or action involved the exercise of a discretion by the Secretary of State or an officer, that the discretion should have been exercised differently, and (b) in any other case, shall dismiss the appeal.”
“Q What if anything does the respondent have to establish to the satisfaction of the appellate body before it can be determined that the appellant’s deportation is conducive to the public good? A. The respondent submits that there is nothing as such that she needs to establish. The correct approach is that set out in EO [Turkey]… Q What is the standard of proof to be applied to anything that the respondent has to establish?”
“The Secretary of State may decide that a person’s deportation is conducive to the public good if (amongst other things): ♦ he has been convicted of a serious offence or has a series of comparatively minor convictions and where the court did not recommend deportation; ♦ he has obtained indefinite leave to remain by deception (but see also: Administrative Removal Procedures chapter 51)”
“(2) The Upper Tribunal may — (a) admit evidence whether or not — (i) the evidence would be admissible in a civil trial in the United Kingdom; or (ii) the evidence was available to a previous decision maker; or (b) exclude evidence that would otherwise be admissible where — (i) the evidence was not provided within the time allowed by a direction or a practice direction; (ii) the evidence was otherwise provided in a manner that did not comply with a direction or a practice direction; or (iii) it would otherwise be unfair to admit the evidence.”
“29. That brings me to the next issue. Counsel for the appellant submitted that the civil standard of proof is applicable to the Secretary of State and to the Commission. This argument necessarily involves the proposition that even if the Secretary of State is fully entitled to be satisfied on the materials before him that the person concerned may be a real threat to national security, the Secretary of State may not deport him. That cannot be right. The task of the Secretary of State is to evaluate risks in respect of the interests of national security. Lord Woolf expressed the point with precision as follows, at p 1254, para 44: "in any national security case the Secretary of State is entitled to make a decision to deport not only on the basis that the individual has in fact endangered national security but that he is a danger to national security. When the case is being put in this way, it is necessary not to look only at the individual allegations and ask whether they have been proved. It is also necessary to examine the case as a whole against an individual and then ask whether on a global approach that individual is a danger to national security, taking into account the executive's policy with regard to national security. When this is done, the cumulative effect may establish that the individual is to be treated as a danger, although it cannot be proved to a high degree of probability that he has performed any individual act which would justify this conclusion. Here it is important to remember that the individual is still subject to immigration control. He is not in the same position as a British citizen. He has not been charged with a specific criminal offence. It is the danger which he constitutes to national security which is to be balanced against his own personal interests." The dynamics of the role of the Secretary of State, charged with the power and duty to consider deportation on grounds of national security, irresistibly supports this analysis. While I came to this conclusion by the end of the hearing of the appeal, the tragic events of11 September 2001 in New York reinforce compellingly that no other approach is possible.”
