18These grounds, which are conveniently dealt with together, require reference to the sentence proceedings.
19His Honour was taken to the details of the Applicant's criminal history and to his custodial record. In doing so, the Applicant's solicitor, Mr Sandilands, pointed out that on the assumption that his calculations were correct, there was a period between 8 March 2012 and 2 June 2012 which the Applicant spent in custody but which did not appear to be referable to any sentence which had ever been imposed upon him for any offence (at T13 L11-16). The following exchange then took place (commencing at T13 L 47):
"Crown: Your Honour the Crown concedes that it appears that that doesn't relate to anything on his criminal history, however my submission is that's completely irrelevant to this current offence.
His Honour: I must say I've had the argument Mr Sandilands has had a long time ago when I was counsel and - -
Crown: Offenders can't be given a free kick just because there seems to be some unaccounted time - -
Sandilands: But he did .. (not transcribable)..in gaol.
Crown: It has no relevance to this offence whatsoever.
His Honour: That may be so in the sense of relevant punishment directly attributable to this offence, however, if he's been punished when there was no reason to punish him; I think I can take that into account.
Crown: It's a matter for your Honour. We don't have any paperwork in that regard and I can't provide any - -
His Honour: There may be, I don't know, it may be simply a refusal of bail in respect of other matters.
Crown: That's right.
His Honour: But - -
Crown: Which is likely in my submission given - -
His Honour: Well unless it's - and I doubt it, very poor record keeping, but it's more likely to be a refusal of bail. And that tends to be kind of confirmed by why you would be transferred from a fulltime custody gaol to a metropolitan remand centre unless you're (sic) status as a sentenced prisoner had changed.
Crown: That's correct.
His Honour: Notwithstanding the fact that he's transferred on the 13th and not the 8th.
Sandilands: Just to assist your Honour, my instructions are, and you won't have it there, is that it was referable to bail refuse (sic) and was referable to a matter that he was ultimately found not guilty of.
His Honour: Right.
Sandilands: They're my instructions.
Crown: In that case your Honour it's - -
His Honour: I hear you Madam Crown.
Crown: Thank you your Honour."
20There was no further reference to the issue in the sentence proceedings, nor was there any reference to it in his Honour's judgment. Evidence was given by the Applicant in the sentence proceedings. He said nothing about his period in custody between 8 March 2012 and 2 June 2012, and, in particular, made no reference to anything which occurred in that period which was said to be relevant on sentence (AB50-58).
21The Applicant's submissions depend upon a construction of what occurred in the District Court during the sentencing submissions which, as outlined above, were relatively brief. The Applicant's submissions require acceptance, by this Court, that the sentencing Judge was invited to take into account (or give credit for) a period between 8 March and 2 June 2012 when the Applicant was in custody, having been refused bail on charges upon which he was ultimately discharged at the Penrith Local Court on 20 August 2012.
22The exchange which took place between his Honour and the representatives of each party was, as set out, somewhat fluid. However, after the solicitor for the Applicant revealed his instructions that the period in question had been served by the Applicant in the circumstances referred to in [19] above, no further submission was advanced that that period ought be taken into account in some way in selecting a starting date for the sentences to be imposed.
23For all of these reasons, the foundation for these grounds is somewhat shaky. The Court should keep in mind concerns which have been expressed where error is said to arise based upon interchanges between the Bench and counsel during submissions: R v Pham [2005] NSWCCA 94 at [11]; R v Thompson [2005] NSWCCA 340; 156 A Crim R 467 at 474-475; [32]. These grounds also appear to strain the limits of permissible grounds of appeal as explained in Zreika v R [2012] NSWCCA 44; 223 A Crim R 460 at 477-478; [79]-[82].
24However, on the assumption that a sufficient foundation is crystallised for Grounds 1 and 2, it is necessary to address them.
25The transcript of the sentence proceedings reveals that the solicitor for the Applicant invited the sentencing Judge to take into account, and give credit to the Applicant for, his time in custody between 8 March and 2 June 2012 for an unrelated matter. The fact that he was discharged with respect to that matter was a factor added very late in the submission, and was unaccompanied by any submission that that aspect operated further in the Applicant's favour. As previously noted, the Applicant made no reference to that time in custody when giving evidence.
26In these circumstances, the bare invitation for the sentencing Judge to take this period into account on sentence ought be taken, at its highest, as an invitation to the sentencing Judge to approach this period as being a form of "credit in the bank" for the Applicant, to be considered on sentence for the later offences committed on 23 August 2012. The Applicant appears to submit that the sentencing Judge was bound to consider this matter and to take it into account in the exercise of the sentencing discretion.
27The decision of this Court in R v Niass appears to stand in the way of that submission. That decision makes it clear that where what is sought to be done is to invite a sentencing court to take into account, as a relevant matter, a period in custody for an unrelated matter leading to acquittal or discharge, that factor is not, in and of itself, relevant to the sentencing exercise.
28Relevant statutory provisions confirm that time for which an offender has been held in custody in relation to the offence for which sentence is to be passed is a mandatory factor to be taken into account on sentence: ss.24(a), 47(3) Crimes (Sentencing Procedure) Act 1999. There is nothing in s.21A Crimes (Sentencing Procedure) Act which supports the Applicant's submission. It is true that s.21A is not exhaustive and factors available to be taken into account at common law remain available. However, this brings one to the decision in R v Niass, which has been applied frequently in this State.
29Later decisions of this Court tend to confirm this approach. Some have involved an acceptance that where other events occur during such a period in custody, those events may bear upon the issue of sentence. However, that is because they relate to the offender's subjective circumstances: R v Evans (NSWCCA, 21 May 1992, unreported); R v Webster and Jones (NSWCCA, 3 August 1992, unreported); R v Chung (NSWCCA, 9 March 1994, unreported); R v David (NSWCCA, 20 April 1995, unreported); R v Hudd (NSWCCA, 5 December 1995, unreported); R v Baartman (NSWSC, Dunford J, 18 December 1988, unreported); R v Karageorge [1999] NSWCCA 213; R v Giam (No. 2) [1999] NSWCCA 378; R v Rozynski [2001] NSWCCA 257; Huntingdon v R [2007] NSWCCA 196 and Kerr v R [2008] NSWCCA 201.
30These decisions confirm an approach that bare reliance on a period in custody for an unrelated matter, without more, is extraneous to the exercise of sentencing discretion for other matters. This is particularly so where there is a broken period of custody, as exists in this case.
31If events occurred during the period in custody which could otherwise be called in aid of the offender's case on sentence, such as marital breakdown, loss of employment, development of illness or other aspects which could bear upon the person's subjective circumstances on sentence for offences later committed, then that may be relevant on sentence. R v Evans appears to be an example of this approach.
32To succeed on Ground 2, it is necessary for the Applicant to demonstrate that the approach taken in R v Niass and subsequent cases is clearly wrong: Green v The Queen [2011] HCA 49; 244 CLR 462 at 490-491 [84]-[85]. In R v Mai (1992) 26 NSWLR 371 at 380, it was said that the Court of Criminal Appeal is not bound by its earlier decisions, but should depart from such decisions with caution, and only when satisfied that the law and justice of the case required such a result. On one view, this approach appears to be less onerous than that described by Heydon J in Green v The Queen. It is unnecessary to consider on the present application whether the statement in R v Mai (at 380) was intended to state a different test to that stated in R v Johns [1978] 2 NSWLR 259 at 262, 264 that this Court is not bound to follow an earlier decision if it was satisfied that the decision is wrong: R v Arnold [1993] 30 NSWLR 73 at 85-86 (Abadee J; Gleeson CJ agreeing at 74). It is sufficient to observe that departure from a previous decision would require a strong conviction that the previous decision was incorrect: R v Arnold at 85E-F; Jimmy v The Queen [2010] NSWCCA 60; 77 NSWLR 540 at 570; [127]. The principle in Green v The Queen is consistent with the general approach when construing uniform national legislation where the rule of comity applies, so that a court at the same level in the judicial hierarchy should not depart from an earlier decision of another court unless convinced that the earlier decision is plainly wrong: R v NZ [2005] NSWCCA 278; 63 NSWLR 628 at 665 [156].
33The Applicant did not submit before this Court that R v Niass, insofar as it related to the "credit in the bank" concept, was wrong or should not be followed. In these circumstances, the issue goes no further.
34Decisions of courts in other States concerning the commencement date of sentences appear to depend upon local statutory provisions, and the approach of Judges in those jurisdictions operating within their own statutory frameworks. To the extent that Ground 2 invites this Court to adopt the reasoning and apply decisions in other States (including R v Renzella [1997] 2 VR 88 and other decisions to which the Court was referred in argument), particular care is needed. This Court has noted that caution should be exercised where matters of practice and procedure in one jurisdiction are relied upon in support of arguments in this jurisdiction: R v NZ.
35The New South Wales decisions in this area should be applied. A proper foundation has not been established for a conclusion that any decision under challenge was plainly wrong and should not be followed. In any event, these decisions appear to be based upon the particular circumstances of each case where the broad statement in R v Niass has been applied. Properly understood, no error is revealed in any of those decisions.
36If it was concluded that the sentencing Judge was indeed asked to take into account this period in custody on sentence, no error has been demonstrated by the Applicant in the circumstances of this case.
37Even if some error was demonstrated, a proper examination of this period could not lead to a result favourable to the Applicant. At the highest, the Applicant can point to about two months in custody against a background of years in custody serving other sentences. There is nothing about this period which would attract any factor which operates in his favour by reference to his subjective circumstances.
38Further, the approach to sentencing in this case would have to take into account (in a manner not applied by the sentencing Judge) that the present offences were committed whilst the Applicant was subject to conditional liberty, being on bail for another alleged offence. Further, factors already operating powerfully against the Applicant on sentence, being specific deterrence and general deterrence, would be further escalated by examination of the circumstances, which saw him committing these serious offences on 23 August 2012, whilst subject to conditional liberty and within three days of being discharged on the matters giving rise to the earlier period in custody.
39Grounds 1 and 2 ought be rejected.
