Ground 2: His Honour erred in breaching the principle of parity
41The appellant complains that relative to the sentences imposed on Lachlan Wilson and upon DS, being respectively 16 years and 2 months and 15 years 11 months and 1 week (each of whom participated with the appellant in the supply of the pseudoephedrine but at more elevated levels in the notional hierarchy of offenders in the syndicate), and relative to the sentence imposed on ES (to whose direction the appellant was subject at all times in the supply phase of the importation of the drug), being an undiscounted sentence of 16 years and 6 months, the appellant's sentence of 15 years and 9 months engenders a justifiable sense of grievance.
42The principle of parity derives from the fundamental norm of equal justice. In Green v The Queen; Quinn v The Queen [2011] HCA 49; (2011) 244 CLR 462, at [28] per French CJ, Crennan and Kiefel JJ, their Honours said of equal justice:
"It requires, so far as the law permits, that like cases be treated alike. Equal justice according to law also requires, where the law permits, differential treatment of persons according to differences between them relevant to the scope, purpose and subject matter of the law. As Gaudron, Gummow and Hayne JJ said in Wong v The Queen:
'Equal justice requires identity of outcome in cases that are relevantly identical. It requires different outcomes in cases that are different in some relevant respect.'"
(References omitted).
43The sense of grievance complained of when the sentence for one offender is compared relative to that of a co-offender or co-offenders is to be assessed objectively governed by considerations of substance rather than form. It is only triggered where differences in the sentences imposed on co-offenders is disproportionate to relevant distinctions in the role each played in the commission of the offence (even if the roles might be differently described or involve different conduct) and in an offender's subjective circumstances. There are necessarily degrees of both similarity and difference in the criminal conduct of co-offenders and in their subjective circumstances. In some cases this requires that different sentences be imposed. However, it is only where the discrepancy between sentences is not reasonably explained by the degree of difference between co-offenders and their offending that the disparity is such that appellate intervention is required. For there to be a justifiable sense of grievance, the disparity must be "gross", "marked" or "glaring" (see the discussion by Howie J in Crystal Lee England v R [2009] NSWCCA 274 at [61]-[67]).
44In Gill v R [2010] NSWCCA 236 at [58], McColl JA (with whom RS Hulme and Latham JJ agreed) observed that an applicant faces considerable obstacles in invoking the parity principle in circumstances where a sentence, said to give rise to a justifiable sense of grievance, was imposed by a sentencing judge who was aware of the sentences imposed on co-offenders and it is clear that the sentence is structured in that knowledge.
45This appellant and his brother were the first of the five convicted co-offenders to be sentenced. Eight months later, in May 2012, Lachlan Wilson was sentenced for his role in knowingly taking part in the supply of the same quantity of drugs this appellant and his brother were involved in supplying. Lachlan Wilson, being sentenced to 16 years and 2 months imprisonment with a non-parole period of 10 years and 6 months, received a sentence 5 months longer in total than the sentence imposed on this appellant, with a differential of only 3 months in the non-parole period. DS, who was sentenced almost 12 months after this appellant, received a sentence of 15 years 11 months and 1 week and a non-parole period of 10 years 4 months and 1 week, only 2 months and 1 week longer than the sentence imposed on this appellant with a differential of 1 month and 1 week in the non-parole period.
46In imposing the sentence on Lachlan Wilson, his Honour referred to the decision in Muldrock v The Queen supra and that this appellant and his brother had been sentenced under an approach to the application of Part 4 Div 1A of the Crimes (Sentencing Procedure) Act 1999 (NSW) that applied at the time of their sentences and that has since been disapproved. In sentencing Lachlan Wilson, his Honour also made specific reference to equal justice considerations and the question of parity when referring to the non-parole periods imposed upon this appellant and his brother eight months earlier. He also expressed the view that, despite the change in the approach to the standard non-parole period post Muldrock v The Queen supra, the non-parole periods he imposed were commensurate with the minimum terms that could properly be imposed for their offending having regard to its objective gravity and their criminal antecedents which denied them some level of leniency. His Honour's observations, whilst entitled to the greatest respect, do not bind this Court on re-sentence, given Muldrock error was conceded by the Crown.
47Similarly, when sentencing DS for his role, which his Honour described as one involving the coordination and supervision of the arrival of the container and unpacking the boxes to isolate the drugs, he referred to the sentences he had already imposed on this appellant and his brother and on Lachlan Wilson. It was in those sentencing remarks that he described the role of this appellant as "the escort" and his brother as "the driver".
48DS's sentence appeal was upheld, in part, on parity grounds when compared with the sentence imposed on Lachlan Wilson (DS v R [2014] NSWCCA 267). He was re-sentenced to a term of imprisonment of 14 years and 6 months, comprised of a non-parole period of 9 years and 6 months with a balance of term of 5 years. The finding of special circumstances was preserved. Lachlan Wilson's sentence appeal (which included a ground that his sentence was disproportionate to the sentence imposed on ES) was dismissed (see Lachlan Wilson v R [2014] NSWCCA 266).
49The sentence imposed on DS after re-sentence leads inevitably to there being an unjustified disparity in the sentence imposed on this appellant and his brother. The necessity for this appellant's sentence to reflect the overriding principle of equal justice will be addressed in the context of re-sentence which, in light of the Crown concession that a Muldrock error is made out, is the inevitable outcome of his sentence appeal.
50Were we not persuaded that the ground of appeal alleging disparity was made out, we would not have intervened to re-sentence on the basis that the sentence imposed at first instance was manifestly excessive, in the sense of it being unreasonable or plainly unjust, after giving due weight to all relevant circumstances particular to this appellant's offending, including the maximum penalty of life imprisonment.
