“(i) the Secretary of State must intend to deport the person and can only use the power to detain for that purpose; (ii) the deportee may only be detained for a period that is reasonable in all the circumstances; (iii) if, before the expiry of the reasonable period, it becomes apparent that the Secretary of State will not be able to effect deportation within a reasonable period, he should not seek the exercise the power of detention; (iv) the Secretary of State should act with reasonable diligence and expedition to effect removal.”
“109. But the risk of reoffending is a relevant factor even if the appellants are right in saying that it is relevant only where there is also a risk of absconding. As Lord Rodger of Earlsferry JSC pointed out in argument, if a person re-offends there is a risk that he will abscond so as to evade arrest or if he is arrested that he will be prosecuted and receive a custodial sentence. Either way, his reoffending will impede his deportation. 110. The risk of reoffending is, therefore, a relevant factor.”
“Overall, I accept that as the period of detention becomes longer, so a greater degree of certainty and indeed proximity of removal is likely to be required. I accept also that there was no certainty that the litigation – the ECtHR proceedings and the application for revocation of the deportation order – would conclude in the Secretary of State's favour, and that it was not possible to predict precisely when they would conclude. However, I think that at all times it could be anticipated that those proceedings would be completed within a reasonable time, and that once they were concluded, if which might be the case the result was in the Secretary of State's favour, then there was no other obstacle to deportation. I think in the circumstances of this case, and taking account of the risk the Claimant presented of absconding and re-offending, that was sufficient.”
“At the time of the receipt of the rule 39 indication there was a realistic prospect that the ECtHR proceedings concerning removal to Somalia would be resolved within a reasonable period: it was possible but it was not apparent that they would drag on as they did. Nor was it apparent that the ECtHR's final decision would be such as to prevent the claimant's removal. I stress “apparent” because that is the word used in the approved formulation of Hardial Singh principle (iii) and in my view it is important not to water it down so as to cover situations where the prospect of removal within a reasonable period is merely uncertain.”
“I adhere to the view that there can be a realistic prospect of removal without it being possible to specify or predict the date by which, or the period within which, removal can reasonably be expected to occur and without any certainty that removal will occur at all. At the time of receipt of the Rule 39 indication in the Claimant's case, although it was not possible to say when the ECtHR proceedings would be concluded, there was none the less a realistic prospect of their being concluded and of removal being effected within a period that was reasonable in all the circumstances.”
