parity
29 The day before he sentenced the applicant, the sentencing judge also sentenced two co-offenders, Kidwell and Watt. It was not contended by either party that the principles of parity applied to the sentences imposed upon Kidwell. He pleaded guilty to thirteen charges, eleven of which were armed robbery, one of assault with intent to rob, and one of robbery inflicting actual bodily harm. He was, at twenty-six, older than the applicant, and had a lengthy criminal history.
30 It is appropriate, however, to have regard to the sentences imposed upon Watt. He pleaded guilty to four offences of armed robbery, all committed jointly with Kidwell, the first of which was the offence at the pharmacy in which the applicant was also involved. This was the only offence in which both the applicant and Watt participated, or, at least, the only offence with which both were charged. Because, his Honour held, two of the offences could not have been proved against Watt without his own admissions, his sentences on those counts were discounted by twenty-five per cent (R v Ellis (1986) 6 NSWLR 603); the sentences on the other two counts were reduced, in recognition of his contrition, by twenty per cent. Watt was thirty-one years of age at the time of the offences, and had a criminal record which commenced when he was a fourteen year old, and had resulted in some short terms of imprisonment. He had had a six year crime free period whilst living in Queensland; none of his prior offences was at the level of gravity of armed robbery. He was a heroin addict. His Honour found special circumstances pursuant to s44 of the Crimes (Sentencing Procedure) Act 1999 and extended the non-parole periods of the sentences.
31 On three of the four charges, and having applied the discounts already mentioned, his Honour sentenced Watt to imprisonment for four years with non-parole periods of two years and eight months. On the fourth charge, he sentenced him to imprisonment for four years and four months, with a non-parole period of two years and ten months. He specified that the first sentence was to commence on 19 February 2002, and the other sentences be accumulated on the non-parole period of the first. The overall effect was a sentence of imprisonment for six years and four months with a non-parole period of five years and six months.
32 The principles of parity in sentencing are well known and need not here be recited. I have already referred to the decisions of the High Court in Lowe and Postigilione. To say that the principles are well known is not to say that their application is always easy.
33 Here, it was only in relation to one of the armed robberies that the applicant and Watt were sentenced as co-offenders. However, the circumstances of Watt's other offences were so similar as to make comparison legitimate. On all points of comparison or contrast except one the exercise favours the applicant. He faced three counts of armed robbery against Watt's four; he had youth on his side; he had a prior exemplary history; he had demonstrated rehabilitation. On the other side of the ledger, two of the applicant's offences were committed whilst he was on bail for the first.
34 Of course, it also has to be observed that Watt's non-parole period is significantly longer than the applicant's.
35 In order properly to compare the sentences imposed it is necessary to engage in something of a reconstruction exercise. The sentences imposed upon the applicant incorporated a thirty-five per cent discount, in part attributable to Cartwright factors, and in part to contrition. Counsel for the applicant submitted that, by adding in the discount, it could be seen that the overall starting point for the total of the sentences was approximately 13.7 years. This is roughly correct. He then submitted that, by a simple mathematical exercise, it could further be seen that the average pre-discount sentence for each robbery (leaving aside the motor vehicle offence) was four and a half years.
36 Watt also pleaded guilty, and his Honour also found that his expressions of contrition were genuine, but he had no entitlement to a reduction corresponding to the applicant's Cartwright discount. Watt's sentences were reduced by twenty and twenty-five per cent respectively, attributable to contrition only.
37 Counsel for the applicant pointed out that the overall head sentence imposed upon Watt was sixteen years and four months. He calculated this as an average sentence of four years and one month for each robbery.
38 I think this mathematical approach should be rejected. A correct appreciation of parity of sentencing is not to be obtained by division of total sentences into portions attributable to individual offences. It is not correct to average multiple sentences in order to determine a tariff for each offence. That would be to circumvent what is required by the decision in Pearce v The Queen [1998] HCA 57; 194 CLR 610. The task of a sentencing judge is to sentence in respect of each individual offence and then determine questions of totality, cumulation and concurrence. The initial exercise involves consideration of the circumstances of the offences, and the offender's subjective circumstances. These last matters were, in the two cases, very different.
39 No argument was advanced in this Court challenging the relative discounts allowed to the two men. Having considered the material contained in a sealed envelope (exhibit A on this application) and bearing in mind that, except where he incriminated himself, Watt's contrition discount was twenty per cent, I am of the view that the decision not to mount such a challenge was a considered and realistic one. It may be inferred that the proportion of the applicant's discount attributable to contrition was, like Watt's, twenty per cent, and the Cartwright discount a further fifteen per cent. That appears to me to be consonant with the material contained in the sealed envelope.
40 The overall sentences, both head sentences and non-parole periods, show Watt was sentenced significantly more heavily than the applicant - as was appropriate.
41 It seems to me that the real complaint made on behalf of the applicant is that each of his robbery sentences was accumulated upon the non-parole period specified in respect of the preceding sentence. In Watt's case, those sentences were successively accumulated upon the non-parole period of the first sentence. But this cannot be shown to have caused any injustice.
