22 The sentence arrived at does not, of itself, bespeak error. It is clear that the sentencing judge did take into account the mitigating factor of S's past, and promised future, co-operation with authorities. Her Honour's reasons were full and careful, and entirely consistent with her having taken this factor into account. There is no merit in this ground of appeal.
Ground 2
23 This ground makes a similar complaint with respect to S's plea of guilty. Section 5(2)(e) of the Sentencing Act 1991 requires a sentencing court to take into account in mitigation of sentence an offender's plea of guilty, and the time at which that plea is entered or offered.
24 For similar reasons to those we have given in relation to ground 1, this ground is without substance. That the sentencing judge took this factor into account is clear from the sentence she imposed and her sentencing remarks.
25 Her Honour stated specifically that the sentence imposed was "far less" than it would have been had it been imposed after a trial. There is nothing in her Honour's sentence which suggests a failure to take S's plea of guilty into account.
Ground 3
26 This ground asserts that the sentencing judge failed to give any, or sufficient, weight to S's "accepted motive" for having committed the offence for which he was sentenced.
27 In his plea before the sentencing judge, counsel for S had submitted that S was motivated purely by his need for a place to care for his horses, and not by the prospect of any profit arising out of the sale of the crop. In her sentencing remarks the sentencing judge said that she was satisfied that S received an immediate benefit by way of a place for him and his horses to live, but that he also expected some future benefit by way of recompense for his work as a caretaker.
28 The judge was cognisant of S's motive and took it into account. There is nothing in the result of this case which could justify any other conclusion. Ground 3 is not made out.
Ground 4
29 As with grounds 1 - 3, ground 4 contends that the judge failed to give "any or sufficient weight" to the limited role of S in the commission of the offence. We would reject it for the same reasons as apply to those other grounds. That is, it is clear from the sentencing remarks that her Honour correctly understood what part S had played. She described him on several occasions - correctly - as "the caretaker of the crop".
30 There was, in short, no failure to take account of S's role. On the contrary, it was expressly adverted to. Moreover, there is nothing in the result arrived at which could justify a different conclusion. This ground also fails.
Ground 5
31 This ground complains that the sentence imposed was manifestly excessive. In Wong v The Queen,[4] Gaudron, Gummow and Hayne JJ described this ground as a "residuary category of error". They observed that appellate intervention on this ground is not justified just because a sentence is "markedly different" from other sentences that have been imposed in other cases. The sentence imposed must be explicable only on the ground of a misapplication of principle, even if the statement of reasons of the sentencing judge does not make such misapplication apparent. Put another way, the sentence must be "unreasonable or plainly unjust".[5]
32 The offence to which S pleaded guilty was introduced into the Drugs Poisons and Controlled Substances Act 1981 in 2001. The seriousness with which it was viewed by Parliament can be gauged from the fact that it carries a maximum sentence of life imprisonment, the same sentence as the most heinous crimes in the criminal hierarchy.
33 Her Honour's sentence in this case was apparently the first sentence to be imposed for the cultivation of a large commercial quantity of cannabis. Taking into account the seriousness with which the law regards the offence, and taking into account all the circumstances of this case, it could not be said that a sentence of six years imprisonment with a non-parole period of three years and nine months was manifestly excessive, either as to the head sentence or as to the non-parole period.
Ground 6
34 This ground complained that the sentencing judge failed to impose a sentence in accordance with the intention she expressed, namely that she would fix a "lower non-parole period than might otherwise have been the case". Mr Holdenson submitted that it was erroneous to describe a non-parole period of three years nine months on a head sentence of six years as being "lower than might otherwise have been the case." He sought to interpret that phrase as stating an intention to impose a "lower than normal" non-parole period. (The submission assumed - incorrectly - that there is such a thing as a "normal" non-parole period. There is no such thing.)
35 In fact, what the learned judge clearly meant was that she would otherwise have had in mind a non-parole period somewhat closer to the head sentence but had fixed a lower non-parole period to take account of the circumstances. There is, again, no reason to doubt that this is what her Honour did. There is no merit in this ground.
Ground 7
36 This ground is that the trial judge erred in giving weight to the submission of the prosecutor, based upon instructions said to have been received by him from the Chief Crown Prosecutor, that to impose a head sentence of less than five years imprisonment would constitute appellable error.
37 Counsel for S had sought a wholly suspended sentence - that is, a sentence of three years' imprisonment or less, wholly suspended. In answer the prosecutor said:
