"4. (1) For the purposes of this Act - (a) any payments or other rewards received by a person at any time (whether before or after the commencement of this Act) in connection with drug trafficking carried on by him or another person are his proceeds of drug trafficking: and (b) the value of his proceeds of drug trafficking is the aggregate of the values of the payments or other rewards. (2) Subject to subsections (4) and (5) below, the Crown Court shall, for the purpose - (a) of determining whether the defendant has benefited from drug trafficking, and (b) if he has, of assessing the value of his proceeds of drug trafficking, make the required assumptions. (3) The required assumptions are - (a) that any property appearing to the court - (i) to have been held by the defendant at any time since his conviction, or (ii) to have been transferred to him at any time since the beginning of the period of six years ending when the proceedings were instituted against him, was received by him, at the earliest time at which he appears to the court to have held it, as a payment or reward in connection with drug trafficking carried on by him: (b) that any expenditure of his since the beginning of that period was met out of payments received by him in connection with drug trafficking carried on by him; and (c) that, for the purpose of valuing any property received or assumed to have been received by him at any time as such a reward, he received the property free of any other interests in it. (4) The court shall not make any required assumption in relation to any particular property or expenditure if - (a) that assumption is shown to be incorrect in the defendant's case; or (b) the court is satisfied that there would be a serious risk of injustice in the defendant's case if the assumption were to be made; and where, by virtue of this subsection, the court does not make one or more of the required assumptions, it shall state its reasons." (Emphasis supplied).
"The indictment covered the dates March to July 1997, but it was clear from the conversations that were overhead that this appellant must have been involved in drug trafficking to a major extent for a period before that. He was, as the judge found, the prime mover, indeed the leader, of the enterprise. As a matter of common sense it can be said that one does not get to that pinnacle in drug trafficking immediately, so it was clear that it would have been a perfectly proper inference to draw that this appellant had been engaged in drug trafficking for some time before May 1997."
"where the drug trafficking was at such a high level it is perfectly proper to conclude that it must have been going on for a considerable time before the appellant built himself up to reach the position that on the evidence he clearly did reach."
