‘[58] We are unable to accept the appellants' submission that the guarantee given in Dr Halchin's letter is “vague”. On the contrary, it is in our view clear. The guarantee given by Dr Halchin is therefore, in our view, an assurance that the conditions of the appellants' detention will not violate their art. 3 rights…The assurance applies to the prisons, and the regimes and accommodation, described in the other letters, and it is not necessary for the Respondents to provide further detail. The assurance is plainly intended to be, and is, binding as between the UK and Romania; and any breach of it could be expected to have significant consequences for relations between the two countries in relation to extradition matters.’
‘[42] In our view, a court hearing an extradition case, whether at first instance or on appeal, has the power to receive and consider assurances whenever they are offered by a requesting state. It is necessary to examine the reasons why the assurances have been offered at a late stage and to consider the practicability or otherwise of the requesting state having put them forward earlier. It is also necessary to consider whether the requesting state has delayed the offer of assurances for tactical reasons or has acted in bad faith: if it has, that may be a factor which affects the court's decision whether to receive the assurances. If, however, a court were to refuse to entertain an offer of assurances solely on the ground that the assurances had been offered at a late stage, the result might be a windfall to an alleged or convicted criminal, which would defeat the public interest in extradition.’
