Following a trial without a jury, the appellant was found guilty of two counts of aggravated robbery.
Prior to being sentenced, the appellant spent various periods of time on remand, both in prison and
on home detention bail.
A total head sentence of six years’ imprisonment was imposed in respect of both offences. This was
reduced by 11 months and 20 days, for time served in custody, to five years and 11 days’
imprisonment. Following this deduction from the total head sentence, a non-parole period of two
years, nine months and six days was fixed.
The appellant appeals on two grounds: namely, the sentencing Judge failed to properly account for
time spent in custody when fixing the non-parole period; and failed to provide any explanation for
not doing so.
HELD by the Court, granting permission to appeal, but dismissing the appeal:
-- 1 of 9 --
In the absence of explicit reference by the sentencing Judge to any reduction of the non-parole period
for time served, specific error has been established. However, having regard to the circumstances of
the offending and the personal circumstances of the appellant, as well as the time served in custody,
this Court would not impose a lesser sentence.
As a matter of sentencing practice, when reducing a sentence for time served in custody, the
preferable approach is to fix both the head sentence and the non-parole period, and then reduce both
for time spent in custody.

STEHBENS v THE KING
[2025] SASCA 16
Court of Appeal – Criminal: Lovell, Bleby and David JJA
1 THE COURT: This is an appeal against sentence. On 15 December 2023,
following a trial without a jury, the appellant was found guilty of two counts of
aggravated robbery contrary to s 137(1) of the Criminal Law Consolidation Act
1935 (SA). The maximum penalty for each offence is life imprisonment.
2 On 29 April 2024, the sentencing Judge imposed a sentence of five years’
imprisonment for each offence and ordered that four years of the sentence for the
second offence be served concurrently with the sentence for the first offence. This
resulted in a head sentence of six years’ imprisonment which was reduced by
11 months and 20 days for time served in custody. Accordingly, a head sentence
of five years and 11 days’ imprisonment was imposed.
3 The sentencing Judge fixed a non-parole period of two years, nine months
and six days.
4 The head sentence and non-parole period was backdated to commence on
21 February 2023.
5 The appellant now appeals against his sentence on the basis that the
sentencing Judge failed to take into account the time spent in custody when fixing
the non-parole period and did not provide any explanation for not giving the
appellant full credit for the time served.
6 The appellant sought an extension of time to bring the appeal.
The circumstances of the offending
7 Briefly, both offences occurred on 1 November 2021 within about two hours
of each other and involved two co-offenders. The first offence occurred at around
5:30pm. The co-offenders attended the Woolworths supermarket at Gilles Plains
wearing motorcycle helmets. One of the co-offenders entered the ‘staff only’ area
and told the service operator he had a taser. He then proceeded to take two boxes
containing cartons of cigarettes and razors, and with his co-offender, left the store
through an emergency fire door. The appellant was waiting in a vehicle a short
distance away. He drove the co-offenders from the store with the boxes of stolen
goods. He was, in effect, the ‘getaway driver’.
8 Later that evening at around 7:45pm, the two co-offenders entered the
Woolworths supermarket at Para Hills. They were again both wearing motorcycle
helmets. One of the co-offenders produced a taser and appeared to activate it in
front of the service operator. He then took a single box of cigarette cartons before
he and his co-offender left the premises. The appellant was again waiting in the
-- 3 of 9 --
[2025] SASCA 16 The Court
2
same vehicle a short distance away. He drove the co-offenders from the store with
the stolen goods.
9 On the same evening, around 50 minutes later, police stopped and searched
the vehicle and located two cardboard boxes labelled ‘Gilles Plains’ and ‘Para
Hills’. Following the search, the appellant was arrested and charged with the
relevant offences.
The appellant’s personal circumstances
10 At the time of sentencing, the appellant was aged 40 years. He is the father
of two children, a son aged around 12 years, and a daughter who died from cancer
at the age of two years.
11 The appellant was born and raised in Adelaide, as the third of four boys. His
parents separated when he was around nine years of age and he initially lived with
his father. The appellant alleged that he was physically and emotionally abused by
his father whilst in his care. He later moved in with his mother until the age of 18,
when he found her deceased at home.
12 The appellant has suffered from poor mental health since he was a teenager.
At about the age of 14, he was threatened by another student with a knife, and he
began hearing voices in his head at night. He also began using methylamphetamine
provided by his father, as a way of managing his mental health.
13 He has been in receipt of a Disability Support Pension since the age of about
14 years and has not had any long-term employment.
14 In a psychiatric report dated 17 March 2022, Dr Raeside considered that the
appellant has an underlying anti-social personality disorder and a substance use
disorder. Dr Raeside described the appellant as having a history of trauma and
instability, behavioural disruption at school and limited education, as well as
ongoing poor frustration tolerance, difficulty with anger management, early onset
of recurrent offending and a long history of methylamphetamine use.
15 The appellant has relevant antecedents. As an adult, he has prior convictions
for the offences of aggravated assault by use of an offensive weapon, aggravated
assault against child or spouse, theft and act likely to cause harm. His antecedents
also reveal that he has demonstrated poor compliance with court orders by
breaching bail on six occasions, breaching bonds on two occasions, driving under
disqualification or suspension three times, breaching community service orders
twice and breaching an intervention order on one occasion.
16 In relation to this offending, the appellant has spent various periods of time
in custody and on home detention. The appellant was:
• remanded in custody for a period of 11 months and five days from
1 November 2021 to 6 October 2022;
-- 4 of 9 --
[2025] SASCA 16 The Court
3
• released on home detention bail for a period of one month, two weeks and
three days from 6 October 2022 to 23 November 2022;
• remanded in custody for a period of 15 days between 23 November 2022 and
8 December 2022; and
• remanded in custody on 16 February 2023.
17 The appellant was sentenced to 13 days’ imprisonment on 22 February 2023
in respect of breaches of bail. That sentence was backdated to commence on
9 February 2023. Accordingly, the appellant has remained in custody on the
aggravated robbery offences since 21 February 2023. He has also spent 11 months
and 20 days in custody, referrable to these offences alone, prior to
21 February 2023.
The sentencing remarks
18 In proceeding to sentence, the sentencing Judge outlined the circumstances
of the offending and the appellant’s personal circumstances in some detail, noting
the appellant’s history of trauma, his considerable difficulties at school and his
underlying anti-social personality disorder and substance use disorder.
19 His Honour referred to defence counsel’s submissions as to a lenient
non-parole period:
Mr Stehbens, your counsel accepted that it is serious offending and did not make any
submissions about suspension of the sentence or home detention. He submitted that I should
consider a shorter than usual non-parole period due to your background and personal
circumstances. He said that you were in contact with your partner and she is willing and
wanting to support you. I am told you are motivated to rehabilitate yourself so that you can
see your own child. I have taken all those matters into consideration.
20 The sentencing Judge then turned to impose sentence:
Mr Stehbens, for count 1 aggravated robbery, I impose a sentence for five years
imprisonment. For count 2, the second count of aggravated robbery, I impose a sentence of
five years imprisonment. I order that four years of that sentence be served concurrently
with a sentence imposed in relation to count 1. Resulting in a total sentence of six years for
both counts.
You were remanded in custody on 1 November 2022. Since then you have spent periods of
time in custody and on home detention but you have remained in custody since
21 February 2023. I reduce your sentence by 11 months and 20 days for you [sic] time in
custody because you did not observe the terms of that bail order. I would not give you any
credit for time spent on home detention. That results in a total head sentence of five years
and 11 days.
In setting your non-parole period I have considered your personal circumstances and your
prospects if rehabilitation. I fix a non-parole period of two years, nine months and six days
backdated to 21 February 2023.
-- 5 of 9 --
[2025] SASCA 16 The Court

The offending is far too serious to suspend. I do not consider it appropriate [for] you to
serve your sentence on home detention.
Appeal Grounds
21 On appeal, the appellant advances two grounds as follows:
1. The sentencing Judge when fixing the non-parole period, failed to
properly take into account the time spent in custody when setting the
non-parole period.
2. The sentencing Judge, failed to deduct the period in custody from the
non-parole period in circumstances where the sentencing remarks fail to
identify how, if at all, the time in custody was taken into account, in the
setting of the non-parole period.
22 The effect of the appellant’s complaint, as articulated at the appeal hearing,
is that the sentencing Judge erred by failing to reduce the appellant’s non-parole
period for the time he spent in custody and failed to provide any explanation for
not doing so. Instead, the appellant submits, his Honour reduced the head sentence
by the relevant period of 11 months and 20 days to account for time spent in
custody, and then fixed the non-parole period by reference to the head sentence
without giving the appellant full credit for the time served.
23 Under s 44(2) of the Sentencing Act 2017 (SA), where a defendant has spent
time in custody in respect of an offence for which the defendant is subsequently
sentenced to imprisonment, the court may, when sentencing the defendant, take
into account the time already spent in custody and ‘make an appropriate reduction
in the term of the sentence’ or ‘direct that the sentence will be taken to have
commenced on the day on which the defendant was taken into custody’ or some
other intermediate date. As was discussed in R v Tsonis1 (in relation to s 30(2) the
predecessor to s 44(2) drafted in the same terms), while the sentencing judge has
a discretion whether to reduce the sentence for time spent in custody referable to
the relevant offences, the sentencing practice is to give the defendant full credit for
time served or to provide good reasons for the decision to depart from that practice.
24 In the present case, there was no dispute that the appellant was entitled to
receive full credit for the time served in custody prior to his bail being revoked for
the last time (namely, 11 months and 20 days), and that the sentence should be
backdated to 21 February 2023. It was common ground that it was necessary, in
the circumstances of this case, to both reduce the sentence for time served and
backdate the sentence. This was so because the appellant had not remained in
custody continuously since his arrest, had served some time on home detention
(although he was ultimately not given any credit for that time) and some of the
time he spent in custody was attributable to a sentence imposed for an unrelated
offence.

25 When a sentencing judge reduces a sentence for time served in custody, the
preferable approach is to fix both the head sentence and the non-parole period and
then reduce both for time spent in custody. This approach explicitly acknowledges
that both the head sentence and the non-parole period have been reduced for the
precise length of time spent by a defendant in custody and provides transparency
for all parties.
26 As this Court explained in Ribbon v The Queen (‘Ribbon’):2
Whilst we consider there was ultimately no error in the approach taken by the sentencing
Judge in reducing the sentence for time served or in the non-parole period fixed, it is not
the preferable approach. In adopting this approach, the sentencing Judge did not directly
refer to the exact period of time served in custody when fixing the non-parole period. Had
the sentencing Judge adopted the alternative approach of reducing both the head sentence
and the non-parole period for time served, her Honour would have specifically referred to
the precise period of time served and the complaint made by the appellant could not have
arisen. That would have ensured transparency in the sentencing process and removed any
perception in the appellant’s mind that the time spent in custody was not properly reflected
in the fixing of both the head sentence and non-parole period. It is important to reiterate
that whilst there is no error in the approach taken by the sentencing Judge, it is not an
advisable approach as it can lead to an opacity in the sentencing process and a sense of
grievance on behalf of a defendant. It is an approach which this Court discourages.
27 It is not necessarily an error for a sentencing judge to reduce the head
sentence for time served in custody and then fix the non-parole period by reference
to the head sentence so long as the time served in custody is in fact taken into
account when fixing the non-parole period.
28 Having regard to the whole of the sentencing remarks, we consider that there
is some uncertainty as to whether the sentencing Judge reduced the non-parole
period for all of the time spent in custody. We have reached that conclusion for the
following reasons.
29 First, the sentencing Judge in his remarks made no explicit reference to
having reduced the non-parole period for time served. While his Honour did refer
to having considered the appellant’s ‘personal circumstances’ and ‘prospects of
rehabilitation’ when fixing the non-parole period, he did not go on to indicate that
the appellant’s personal circumstances included time served in custody or that he
had reduced the non-parole period for all the time served, it being common ground
between the parties that the appellant was entitled to full credit for time spent in
custody.
30 In this regard, the present case can be distinguished from Ribbon, where the
sentencing Judge made explicit reference to the fact that she had taken the time
2 Ribbon v The Queen [2022] SASCA 15 at [40] (Livesey P, Doyle and David JJA); see also
Owens v The King [2024] SASCA 65 at [6] (Lovell, Doyle and David JJA), Burdon v The King [2023]
SASCA 71 at [18]-[21] (Livesey P, Bleby and David JJA).

[2025] SASCA 16 The Court

served into account when fixing the non-parole period, although she did not
proceed to arithmetically deduct that period.
31 Secondly, contrary to the respondent’s submissions, the fact that the
non-parole period represents only 61 per cent of the head sentence (once time
served is taken into account) is not necessarily indicative of the non-parole period
having been reduced for all of the time served. It is to be accepted that the
non-parole period could be regarded as lenient given the appellant’s personal
circumstances including his antecedents and previously poor compliance with
court orders. Even so, in the absence of any explicit reference to a reduction to the
non-parole period for time served, there remains an opacity to the sentencing
remarks. It is simply not clear whether the non-parole period has been reduced on
account of all the time spent in custody or by an undisclosed proportion of it.
32 In those circumstances, we consider that specific error has been established
and the Court’s power to intervene and re-sentence is enlivened. However, having
regard to all the materials before this Court as to the circumstances of the offending
and the appellant’s personal circumstances, and after reducing both the head
sentence and the non-parole period for the time spent in custody, we would not
impose a lesser sentence.3
33 To illustrate, we would have proceeded to sentence as follows. Like the
sentencing Judge, we would impose a head sentence of five years’ imprisonment
for each offence. Acknowledging that each offence was a separate incursion into
crime, but bearing in mind the proximity in time between the two offences, we
would order all but one year be served concurrently resulting in a head sentence of
six years’ imprisonment. Taking into account the appellant’s personal
circumstances including his compromised mental health, difficult upbringing and
antecedents, and what we consider to be his limited prospects of rehabilitation
given his numerous breaches of court orders and his relatively poor performance
on home detention bail, we would fix a non-parole period of four years’
imprisonment. This is a higher proportion of the head sentence than the non-parole
period imposed by the sentencing Judge. We would reduce the head sentence and
non-parole period by 11 months, 20 days resulting in a head sentence of five years,
11 days with a non-parole period of three years, 11 days. We would backdate the
sentence to commence on 21 February 2023.
34 It is evident from undertaking this sentencing exercise, that the sentence we
would impose is in fact a higher sentence than that imposed by the sentencing
Judge. Consequently, in the separate and independent exercise of our sentencing
discretion, we do not consider that a lesser sentence is warranted, and for that
reason we dismiss the appeal.
35 It is worth re-iterating once more that the better approach for sentencing
judges, when taking into account time served, is to fix the appropriate head
3 Kentwell v The Queen (2014) 252 CLR 601.

[2025] SASCA 16 The Court
7
sentence and non-parole period and then reduce both for time spent in custody.
This approach ensures transparency in the sentencing process and removes any
perception in a defendant’s mind that time spent in custody has not been properly
taken into account in fixing both the head sentence and non-parole period. This is
particularly so, in a case such as this, where the time served is not insignificant.
Again, this Court discourages the approach adopted by the sentencing Judge in this
case, which has been the subject of disapprobation in numerous recent authorities.
Proposed orders
36 We grant an extension of time to file the appeal notice; grant permission to
appeal but dismiss the appeal.
