[48] It is not infrequent that, where the offences arise out of one criminal enterprise, concurrent sentences will be imposed - but this is not an inflexible rule: Wilkins (1988) 38 A Crim R 445 (per Lee CJ at CL and Carruthers J, Allen J dissenting). The practice should not be followed where wholly concurrent sentences would fail to take account of differences in conduct, the subject of punishment on each count: Pearce v The Queen (1998) 194 CLR 610 at 624 (see also 621 to 622)."
In Cahyahi v The Queen (2007) 168 A Crim R 41 Howie J, with the concurrence of the other members of the court, said at 47 (27):
"In any event there is no general rule that determines whether sentences ought to be imposed concurrently or consecutively. The issue is determined by the application of the principle of totality of criminality: can the sentence for one offence comprehend and reflect the criminality for the other offence? If it can, the sentences ought to be concurrent otherwise there is a risk that the combined sentences will exceed that which is warranted to reflect the total criminality of the two offences. If not, the sentences should be at least partly cumulative otherwise there is a risk that the total sentence will fail to reflect the total criminality of the two offences. This is so regardless of whether the two offences represent two discrete acts of criminality or can be regarded as part of a single episode of criminality. Of course it is more likely that, where the offences are discrete and independent criminal acts, the sentence for one offence cannot comprehend the criminality of the other. Similarly, where they are part of a single episode of criminality with common factors, it is more likely that the sentence for one of the offences will reflect the criminality of both."
In the present case I do not consider that the offences committed on different days, even though only a very few days apart, should be regarded as a single discrete episode of criminality, although it remains relevant that all the offences were committed within a very short period. As the authorities I have quoted indicate, whether offences are regarded as discrete acts of criminality or as forming part of a single episode of criminality is not decisive of whether sentences should be concurrent or cumulative or of the extent to which they should be concurrent or cumulative.
The fundamental question to be determined in the present case is whether it was within the sentencing judge's discretion to regard the aggregate of the sentences he was imposing,…as justly reflecting the total criminality of the applicant or whether the aggregate sentence exceeded the upper limit of the range of total sentences within his Honour's discretion. (pars 32-35)
54 Counsel pointed out that the overall effect of the sentences imposed upon him for counts 2 and 4 was a total sentence of 5 years imprisonment with a non-parole period of 3 years. It was contended in written submissions that the sentences for these counts should have been made, if not totally, then substantially concurrent because the tablets in question were all from a common source. It was submitted that "it was a matter of happenstance that on 15 September, the two quantities of tablets became separated and thus formed the basis for two separate counts of possession on the same day".
55 The short answer to the submission is that the sentences imposed in respect of counts 2 and 4 were only partially cumulative. The sentence in respect of count 2 was accumulated but by only six months upon the sentence imposed for count 4. Furthermore, even though the tablets came from the same source what were discovered were two very substantial quantities of tablets in separate locations. It was open to the sentencing judge to structure those sentences in the manner in which he did.
56 A further complaint was made that the sentence for count 4 was wholly cumulative upon the sentence for count 3 notwithstanding the fact that the two offences "were intimately connected and both arose from his controlling the tablets on the particular day". Although at first blush it may appear that there is some substance in the applicant's submission, it is necessary, as the authorities make clear, to have regard to the overall effect of the sentences which were imposed upon DTT and to the fashion in which the individual sentences were structured in determining whether or not error has been established. It follows that it is not appropriate to simply consider only some of the individual sentences imposed in isolation from the remainder. As I observed at the outset, the sentence which was imposed in respect of count 3 is wholly subsumed within the sentence which was imposed in respect of count 1, whilst the sentence which was imposed in respect of count 4 is wholly subsumed within the sentences which were imposed in respect of counts 1 and 2. In other words, in practical terms, DTT received no additional punishment for having committed the offences which gave rise to counts 3 and 4. Viewed in that light, the applicant can have no legitimate basis for complaint.
57 I return then to the question of whether the sentences were manifestly excessive. Although no standard non-parole period applied, the offences committed by the applicant were properly characterised by the sentencing judge as being higher than the mid-range. Not only did the applicant breach his employer's trust by stealing the tablets in the first place, but he also conceded, as must have been obvious, that he had committed these offences for financial gain. The sheer volume of the material in his possession indicates the scale of the operation and the size of the reward which he expected to reap. The evidence revealed that as a result of this enterprise in which the applicant played a significant role, a very large quantity of methylamphetamine was potentially going to be made available for end users: see generally R v Cousins (2002) 132 A Crim R 444 at 450. As I have said the effective total term of imprisonment was 6 years with a non-parole period of 4 years. Although there were a number of factors upon which the applicant was entitled to rely by way of mitigation, in my view the overall effective sentence, as well as the individual sentences, at which the sentencing judge arrived were within the range of a proper exercise of the sentencing discretion. I would reject this Ground of Appeal.
