(3) In deciding whether or not to make a direction under subsection (2)(a) with respect to a sentence of imprisonment, and in deciding the day on which the sentence is taken to have commenced, the court must take into account any time for which the offender has been held in custody in relation to the offence to which the sentence relates.
18 Section 24 of the Act provides:
In sentencing an offender, the court must take into account:
(a) any time for which the offender has been held in custody in relation to the offence …
19 Other than in exceptional circumstances, if an offender has been held in custody from the date of arrest to the date of sentence solely in relation to the offence for which he is being sentenced, the Court will backdate the sentence so that it commences upon the date the applicant went into custody referrable to that offence - R v Close (1992) 31 NSWLR 743 at 748, R v Cook [1999] NSWCCA 234 at [39].
20 However, in this case, the applicant was not in custody from the date of arrest to the date of sentence solely in relation to the offence on 10 July 2005. He was in custody during that period due to both the revocation of his parole for the offences for which he was sentenced on 18 March 2004 and the subject offence on 10 July 2005. As Hunt CJ at CL (as he then was) said in R v Andrews (NSWCCA unreported 28 April 1993):
The parole is revoked because, by reason of the further offence committed, it has been demonstrated that the applicant was unable to adapt to normal lawful community life and therefore is no longer entitled to parole in relation to the earlier offence.
21 In Callaghan v R [2006] NSWCCA 58 this Court per Simpson J (James and Hall JJ agreeing), held a sentencing judge has a discretion to backdate to some point (not necessarily to the date of revocation of the parole) even where the period in custody is not wholly the result of the offence for which the applicant is being sentenced.
22 Such a discretion is a wide one. In Markarian v R (2005) 215 ALR 213 at [27] the High Court confirmed:
Judges at first instance are to be allowed as much flexibility in sentencing as is consonant with consistency of approach and as accords with the statutory regime that applies.
23 The subject offence was a significant one. It was committed in circumstances where imprisonment for previous similar offences had had no effect, where the offence was committed in breach of parole and where it was, as his Honour observed, an offence which was both serious and odious. To back date the subject sentence from the date of its imposition would, depending on the extent of the backdate, have resulted in the non-parole period of the subject sentence being entirely, or almost entirely, subsumed by the balance of the parole sentence. This, in all probability, would result in the applicant receiving no actual punishment for the subject offence.
