32 The respondent was able to rely upon a body of material which had the effect of significantly ameliorating the otherwise appropriate sentences. Firstly, he pleaded guilty at the first available opportunity, a matter which the sentencing judge assessed should attract a discount at the top of the available range. Secondly, the respondent provided assistance to the authorities, the value of which His Honour described as being at "the higher end of the scale". The sentencing judge also found that the respondent was genuinely remorseful.
33 A generous discount for assistance was warranted in this case, as the Crown readily accepted. Not only had the respondent, upon his arrest, engaged in the dangerous activity of wearing a listening device in order to capture his conversations with Zakhem, but he had also actively assisted the authorities in relation to the activities of other persons. He is the critical witness in the prosecution of Zakhem. In respect of 8 of the 11 charges brought against Zakhem, the Crown is totally dependent upon the evidence of the respondent. In respect of the 3 remaining matters, his evidence is supported by material contained in telephone intercepts.
34 The respondent has agreed to give evidence not only against Zakhem but also against at least five other persons. Moreover, the respondent disclosed information about offences and offenders of which the authorities were otherwise unaware. The material constituting the respondent's assistance to the authorities has been placed before the Court. Its significance is readily apparent and requires no further elaboration.
35 The respondent is being held in protective custody in order to ensure his ongoing safety. The sentencing judge observed that the respondent "is under maximum protection and is confined to his cell for a period of 16 hours a day". His Honour was also made aware that the premises occupied by the respondent's mother had been the subject of what was described as a "drive by" shooting, although fortunately no-one was injured. There was other material which indicated that the respondent had been the subject of death threats.
36 The respondent was granted bail following his arrest in order that he could further assist the authorities. He remained on bail, upon stringent conditions, until 12 August 2005. His Honour treated the period which he spent on bail as a form of "quasi-custody".
37 In fixing the sentences to be imposed in respect of each of counts 1 - 4, the sentencing judge commenced by fixing a notional head sentence of 8 years. His Honour reduced that sentence in each case by 25% (to 6 years) to reflect the plea of guilty, which he then reduced by a further 50% to give effect to the respondent's assistance to the authorities, thus arriving at a head sentence in each case of 3 years. His Honour then made a finding of "special circumstances" by reason of the respondent's favourable prospects of being rehabilitated and the fact that he could benefit from a longer period on parole.
38 It is to be observed that the effect of what his Honour did was to produce an aggregate discount in each case of 62.5% for the respondent's plea of guilty and remorse and his assistance to the authorities. His Honour allowed the same aggregate discount in relation to count 5. His Honour could equally have allowed for a combined or "rolled-up" discount: see R v Waqa (No 2) [2005] NSWCCA 33 and R v Hovan [2005] NSWCCA 179. However in the final analysis that issue is of no real moment in the present case.
39 The Crown at first instance drew the sentencing judge's attention to this Court's decision in R v NP [2003] NSWCCA 195, in which an overall discount for a plea of guilty and assistance to the authorities of 60% had been allowed. In that case, Simpson J observed that:
The result of the rigorous application of what have become relatively standardised discounts (especially where a considerable discount for a plea of guilty is added to an even more considerable discount for significant assistance) can, on occasion, cause a sharp intake of breath, but that is the result of the application of correct and established legal principle. The result can appear to be disproportionate to the offence(s). Sentencing judges (as in this case) have to balance the need to impose proper punishment with the need to recognise the benefits to the criminal justice system gained by pleas of guilty and assistance to authorities. The correct balance is not always easy to achieve.
This is where s23(3) of the Crimes (Sentencing Procedure) Act 1999 demands consideration, and, sometimes, application. By that subsection, a sentencing judge allowing a discount for assistance to authorities, is required, notwithstanding, to ensure that the resulting sentence is not unreasonably disproportionate to the nature and circumstances of the offence(s). (pars 49-50)
40 It is unnecessary however to further consider this aspect of the matter as the Crown does not challenge the various discounts which were afforded to the respondent. Nor does it challenge the individual sentences imposed in respect of counts 1 - 4. It described them as "lenient" but acknowledged, in so doing, that the respondent was not the principal offender.
