20 The applicant's second ground was the central focus of the application. This ground challenged the sufficiency of the discount allowed by the judge on account of the applicant's assistance to the authorities.
21 The judge took into account the applicant's assistance to the authorities observing:
"I believe that in each case a discrete quantifiable discount on the ground of assistance to the authorities should be given. I take into account not only the fact that he gave past assistance but also that he was willing to give evidence and it was not his decision that he not be called" (RS 13).
22 His Honour went on to refer to the risks to which the applicant had exposed himself by reason of his assistance to the authorities and to note the contents of Ex R.
23 Section 16A(2)(h) of the Crimes Act 1914 (Cth) requires the Court, when passing sentence, to take into account the degree to which the offender has co-operated with law enforcement agencies in the investigation of the offence or of other offences.
24 With respect to each charge the judge specified his starting point and then proceeded to make an allowance pursuant to s 16G of the Crimes Act to take account of the circumstance that remissions are not available in New South Wales. Each of the sentences was reduced by one third on this account. Next the judge quantified the discount to be applied in respect of the applicant's early plea of guilty. Finally he quantified a discount to reflect the applicant's assistance to the authorities rendered as at the date of sentence.
25 With respect to the first charge his Honour's starting point was a sentence of fifteen years imprisonment. The s 16G discount reduced this provisional sentence to one of ten years imprisonment. His Honour allowed a twenty percent discount for the early plea of guilty, thus reducing the sentence to one of eight years imprisonment. He then deducted a further two years to reflect the applicant's assistance to the authorities.
26 With respect to the second charge his Honour's starting point was one of twenty-one years imprisonment. After making an allowance pursuant to s 16G his Honour arrived at a sentence of fourteen years. He allowed a discount of approximately twenty percent to reflect the applicant's plea of guilty. This reduced the sentence to eleven years. As his Honour noted, the effect of rounding off the sentence in this way was to allow a discount slightly greater than twenty percent. He then allowed a further reduction of two years to reflect the applicant's assistance to the authorities.
27 The discount allowed in respect of the applicant's assistance to the authorities and his plea of guilty in the aggregate amounted to a forty percent reduction of the sentence imposed on the first count. The aggregate discount with respect to the second charge was one of thirty-six percent.
28 Mr Odgers submitted that after allowance is made for the s 16G reduction, the overall sentence proposed by the judge was one of twenty-four years imprisonment. In total nine years was deducted from this provisional sentence to reflect both the pleas of guilty and the assistance to the authorities. This reduction may be expressed as an aggregate discount of 37.5 percent. On this analysis of the aggregate sentence the pleas of guilty attracted a discount of 20.8 percent while the assistance to the authorities represented a discount of 16.7 percent. It was the latter figure that was said to demonstrate error.
29 In his written submissions Mr Odgers contended that the range of discounts for assistance to the authorities has been expressed to be in the order of 20 to 50 percent. In this regard he cited Pang (1999) 105 A Crim R 474; Hammoud [2000] NSWCCA 540; Smith [2001] NSWCCA 279.
30 In Pang Wood CJ at CL(in a judgment with which the other members of the Court concurred) observed at [13]:
"There is no fixed tariff for the reduction that should be given for assistance, and so far no guideline judgment has been delivered in this area. However, the discount customarily given in this State for assistance, has ranged between twenty and fifty percent of the sentence that would otherwise have been imposed: Chu (unreported, Court of Criminal Appeal, NSW, No. 60232 of 1998, 16 October 1998) and Behar (unreported, Court of Criminal Appeal, NSW, No. 60363 of 1998, 14 October 1998)."
31 In Pang Wood CJ at CL considered a discount of 25 percent to be an inadequate reflection of the applicant's assistance to the authorities. An appropriate discount was held to be one of 50 percent. The applicant in Pang had pleaded guilty to a charge of being knowingly concerned in the importation of a quantity of heroin into Australia. Significantly, when one looks to the discount allowed by the sentencing judge and to the discount fixed by this Court upon the re-sentencing, it is apparent that no quantified separate discount was allowed for the plea of guilty. Pang was decided before the decision of this Court in Thomson and Houlton [2000] NSWCCA 309; 49 NSWLR 383. That case concerns the discount to be allowed in recognition of the utilitarian value of a plea of guilty with respect to the sentencing of offenders for State offences. The principles enunciated therein are not without relevance when sentencing offenders for Federal offences; Bugeja [2001] NSWCCA 196. In Thomson and Houlton Spigelman CJ noted that it had not been the practice in this State to quantify a separate discount for the plea of guilty at [73]. The guideline proposed in that case emphasised the desirability of a sentencing judge quantifying the effect of the plea on the sentence so far as it was appropriate to do so. It was said that where other matters by way of discount are to be quantified (including assistance to the authorities) it may be appropriate to nominate a single combined discount at [160]. See, also R v Sharma [2002] NSWCCA 142.
32 In Pearce v The Queen (1998) 194 CLR 610 McHugh, Hayne and Callinan JJ observed at 624:
"Sentencing is not a process that leads to a single correct answer arrived at by some process admitting of mathematical precision. It is then all the more important that the proper principle be applied throughout the process."
33 It is apparent that his Honour took into account the applicant's assistance to the authorities in reduction of the sentences with respect to each of the offences. The question is whether his discretion miscarried by reason that he gave insufficient weight to this consideration.
34 In written submissions the Crown acknowledged the importance of assistance to the authorities of the character of that provided by this applicant. The Crown acknowledged that the assistance in this case had been valuable. The overall discount, taking into account both the plea of guilty and the assistance, was described by the Crown as falling, "at the lower end of the available range". In the Crown's submission it was within the range of the proper exercise of discretion.
35 The parties invited us to have regard to the remarks on sentence of the trial judge in the proceedings brought against Betancur following his conviction in respect of the July 1999 importation. As I have noted, Betancur had not been dealt with at the date this applicant was sentenced.
36 Betancur was sentenced upon the basis that it was he who was "calling the shots … here in Australia and Gomez who was obeying". He was sentenced to a term of seventeen years and six months imprisonment with a non-parole period of ten years and six months to date from 10 August 2001. Betancur had no claim for a discount in respect of his plea or assistance to the authorities.
37 It is to be observed that Betancur was sentenced in respect of one offence only (albeit this was the more serious of the two importations of which the applicant was convicted). While acknowledging that Betancur thus stood in a different situation to the applicant, Mr Odgers contended that it was relevant to have regard to his sentence in considering whether the discount given to the applicant for his assistance sufficiently reflected the public interest that offenders be encouraged to supply information to the authorities which will assist them in bringing other offenders to justice and to give evidence against those other offenders; Regina v Cartwright (1989) 17 NSWLR 243 per Hunt J and Badgery-Parker J at 252.
38 It is rarely appropriate in cases of this sort for the Court to detail the assistance the subject of the discount. I do not propose to do so on this occasion. It is sufficient to observe that the applicant's assistance was substantial.
39 I am mindful that considerations of an offender's assistance to the authorities should not be permitted to subsume a consideration of the criminality involved in his or her offending. In sentencing Federal offenders as much as in the sentencing of State offenders a discount reflecting assistance to the authorities and a timely plea of guilty must not be allowed to produce a sentence which is disproportionate to the nature and circumstances of the offence. In each case it is necessary to achieve an appropriate balance. In the investigation and prosecutions of persons associated with major drug importation syndicates there exist strong grounds for the courts being seen to encourage offenders to assist the authorities. In this respect I have regard to Gleeson CJ's observations in R v Gallagher (1991) 23 NSLWR 220:
"There is what might be called the utilitarian consideration involved in encouraging persons to provide information which will permit the apprehension and successful prosecution of other offenders. Public opinion seems to accept this as reasonable enough in a case where, for example, a middle level dealer in a drug operation provides information enabling the apprehension and prosecution of more senior persons in the organisation. The approach seems to be less readily accepted in some other circumstances, especially in cases where there is an identifiable victim of violent crime, or where imprisoned informers, sometimes of extremely doubtful reliability, are seen to be taking cynical advantage of a system which may lend itself to exploitation by the unscrupulous."
