"In relation to Mr Lawes there is, in my judgment, on the face of the report, no evidence of any benefit. In relation to the others there is, on the basis of the reports, evidence from the Defendants' own interviews that they have got into their possession controlled drugs which had been used either for their own purposes or for the purposes of their co-Defendants, who are addicted to drugs. They no longer have any assets whatsoever and, given their chaotic life-styles, it is unlikely that they will have any substantial assets in the foreseeable future. If I make the assumptions that I am entitled to make under Section 10 it seems to me that there is a serious risk of injustice to the three Defendants against whom there is some evidence of benefit, in that such benefit they have over a period of years was ephemeral, it was put into drug abuse and to have a Confiscation Order hanging over their heads in the future neither is of assistance to Society, because the enforcement of it leads to great expense, nor to the Defendants and I, therefore, make no Confiscation Orders in relation to any of these Defendants."
"But the court must not make a required assumption in relation to particular property or expenditure if-- (a) the assumption is shown to be incorrect, or (b) there will be a serious risk of injustice if the assumption were made."
"The risk of injustice must arise from the operation of the assumptions in the calculation of benefit and not from eventual hardship in the making of a confiscation order (Dore[1997] 2 Cr App R(S) 152 ; Ahmed[2005] 1 WLR 122 ). What is contemplated is some unjust contradiction in the process of assumption (eg double counting of income and expenditure), or between an assumption and an agreed factual basis for sentence (see Lunnon[2005] 1 Cr App R(S) 111 ; Lazarus [2005] Crim LR 64)."
