"The Secretary of State, in deciding whether it is conducive to the public good that a person should be deported, is entitled to have regard to all the information in his possession about the actual and potential activities and the connections of the person concerned. He is entitled to have regard to precautionary and preventative principles rather than to wait until directly harmful activities have taken place, the individual in the meantime remaining in this country. In doing so he is not merely finding facts but forming an executive judgment or assessment. There must be material on which proportionately and reasonably he can conclude that there is a real possibility of activities harmful to national security but he does not have to be satisfied, nor on appeal to show, that all material before him is proved, and his conclusion is justified, to a high civil degree of probability . Establishing a degree of probability does not seem relevant to the reaching of a conclusion on whether there should be a deportation for the public good..."
"25. In conclusion, even though the Commission has powers of review both fact and of the exercise of the discretion, the Commission must give due weight to the assessment and conclusions of the Secretary of State in the light at any particular time of his responsibilities..."Per Lord Slynn at p.184 a-f.
"But the question in the present case is not whether a given event happened but the extent of future risk. This depends upon an evaluation of the evidence of the appellant s conduct against a broad range of facts with which they may interact. The question of whether the risk to national security is sufficient to justify the appellant s deportation cannot be answered by taking each allegation seriatim and deciding whether it has been established to some standard of proof. It is a question of evaluation and judgment, in which it is necessary to take into account not only the degree of probability and prejudice to national security but also the importance of the security interests at stake and the serious consequences of deportation for the deportee."Per Lord Hoffmann at p. 194 c-e. Identical principles apply in an exclusion case, such as this, as in a deportation case, such as Rehman.
