26 Turning first to the range identified in previous decisions of this Court as being appropriate for sentences of this kind, a number of previous decisions were cited to us in argument. In Scott v The State of Western Australia [2006] WASCA 28, a sentence of 3 years' imprisonment (imposed after the transitional provisions came into effect), following a conviction of conspiracy to possess methylamphetamine with intent to sell or supply, was reduced to a period of 2 years' imprisonment on appeal. The quantity of methylamphetamine, the subject of the conspiracy, was substantial - approximately two kilograms. However, the circumstances of that case were very different to the present cases. The offender's involvement in the conspiracy was described on appeal as "very slight". She was not involved in the initial discussions of her two co-conspirators, when they arranged to acquire the drug. She was not involved in the planning or setting up of the transaction in any way other than the provision of her credit card details to enable the drug courier to hire a vehicle to be used for the purpose of conveying the drugs. Her co-conspirators each received terms of 7 years' imprisonment (equivalent to 101/2 years' imprisonment prior to the commencement of the transitional provisions). There had been a delay of approximately 4 years between apprehension and trial, part of which period had been used by the offender to undertake a step towards rehabilitation by ending her relationship with her co-offender. In the view of the majority of the Court, delay of that magnitude would not, of itself, have been a mitigatory factor, other than the fact that the time was used to provide evidence of rehabilitation. Having regard to the circumstances of that case, and the very limited involvement of the offender in the conspiracy, and taking account of the sentences imposed upon her co-conspirators, there is nothing in that case that would support the proposition that the sentences imposed in these cases were outside the range applicable to offences of this type. Nor is there anything in the observations of the Court in that case that would suggest the approach taken by the sentencing Judge in these cases to the issue of delay was inappropriate or erroneous in principle.
