28. In the end result, his Honour determined that the sentence was neither manifestly excessive nor infected by any error.
29. Whilst it is from his Honour's decision that this appeal lies, the success or otherwise of the appeal must be measured against the Magistrate's sentence. The circumstances in which an appeal court may interfere with the exercise of the discretion reposing in the sentencing judge are well known and do not need repeating: House v The King [1936] HCA 40; (1936) 55 CLR 499 at 505; Lowndes v The Queen [1999] HCA 29; (1999) 195 CLR 665; and Dinsdale v The Queen [2000] HCA 54; (2000) 202 CLR 321.
30. The maximum penalty for an offence of this kind is four years: s 29(3) of the Act (as it was then). Parliament has taken the view that this offence is less serious than a like offence which causes the death of another person. For that offence the penalty is seven years: s 29(2) of the Act.
31. The Magistrate could not pass a sentence of imprisonment greater than two years. Section 375 of the Act provides that the Magistrates Court can dispose of a matter carrying a maximum sentence of this kind where a party pleads guilty to the charge and the Court is of the opinion that the case can properly be disposed of summarily by sentencing the accused person, and the defendant has consented to the Magistrates Court so disposing of the matter. If the Magistrates Court disposes of a case summarily under the Act, the Court may not impose a sentence of imprisonment exceeding two years: s 375(10) of the Act. If, on the other hand, the Court is of the opinion that the case cannot properly be disposed of summarily or the defendant has not consented to it being so disposed of, then the Court must commit the accused person to the Supreme Court. In those circumstances, the procedure is governed by s 90A of the Magistrates Court Act 1930: s 375(9) of the Act.
32. It may be inferred that the Magistrate in this case decided that the case could be disposed of summarily and that the restriction on her sentencing powers did not mean otherwise. In the end result, she sentenced the appellant to a period of imprisonment greater than two years because, presumably, she must have been of the opinion that a sentence of 18 months would not be adequate to address the appellant's criminality. However, the appellant, through his counsel, eschewed any argument based upon the proposition that the penalty imposed by the Magistrate meant that the Magistrate should not have disposed of the matter summarily.
33. The appellant argued on this appeal that the sentence was manifestly excessive in that it 'offended against the principles requiring parity in sentencing across the range of those convicted of the offence in question. The facts did not indicate that this was in the worse case category despite the undoubtedly serious injuries that were caused'. Further, it was submitted the Magistrate had erred in accumulating the sentences in the way that she did which led to a head sentence which was 'one of the longest head sentences imposed in the ACT [in] respect of all culpable driving sentences including offences against s 29(2) of the Act (culpable driving causing death)'.
34. In particular, it was argued that the Magistrate had fallen into error by failing to have sufficient regard to matters personal to the appellant. It was argued that the appellant was only 19 at the time when these offences were committed; he had no prior convictions; he had expressed contrition for his actions; he had pleaded guilty at the first available opportunity; and he suffers from mental health problems.
35. In all of those circumstances, it was submitted he was not the type of offender who should be used as an instrument for general deterrence.
36. The appellant's counsel went even further in his oral submissions. He submitted that the sentencing practice in the ACT was that a sentence in cases of this kind would not involve the serving of full time custody. In the alternative, he contended that there was an established principle that in fixing the period of actual custody the Courts 'will give generous and indeed overwhelming weight to matters subjective to the offender'. The appellant's submissions continued to change during the hearing of the appeal and it will be necessary to say more of those submissions later.
37. There are some matters in the appellant's counsel's submissions that may be disposed of quickly. The appellant was not sentenced as though this was the worst case category. He was sentenced to imprisonment for 18 months on each conviction where the maximum penalty that could be imposed was four years.
38. We do not agree with the appellant's counsel's oral submission that there is any principle that, for offences of this kind, the Court must give generous and indeed overwhelming weight to matters subjective to the offender. Nor do we agree that there is any principle that in relation to offences of this kind any outcome will not involve the serving of a period of imprisonment. Both propositions are contrary to the provisions of the Act and the authorities on sentencing.
39. There were a number of steps that needed to be followed in the process of imposing a sentence upon this offender. First, the Magistrate had to make findings in relation to the circumstances of the offence. Secondly, she had to consider the matters subjective to the appellant. She then had to decide whether, having regard to both of those matters and the other principles relating to sentencing, a sentence of imprisonment needed to be imposed. A sentence of imprisonment would not be imposed unless no other penalty was appropriate in all of the circumstances of the case: s 345 of the Act. If she decided that a sentence of imprisonment was warranted, she next had to decide whether such a sentence ought to be imposed upon both of the convictions. If that was her view, then she had to decide whether the sentence of imprisonment imposed on the two convictions ought to be cumulative or concurrent. Having fixed the head sentence, the Magistrate needed to consider whether the sentence needed to be immediately served or suspended or partly suspended. If the sentence was to be two years or less, the options of periodic detention or community service needed to be considered. If the sentence was of one year or longer, to be served by way of immediate custody, the Magistrate needed to fix a non-parole period.
40. In so proceeding, the Magistrate needed to keep in mind the purposes for which a sentence is imposed: s 341 of the Act. The Magistrate had to take into account the current sentencing practice: s 342(1)(q) of the Act. She also had to take into account all of the relevant matters referred to in s 342 of the Act. One of those matters is deterrence and, in particular, general deterrence. Another is, of course, the personal circumstances of the offender: s 342(1)(i), (j) and (m) of the Act. She also had to have regard to the early plea and any demonstration of contrition or remorse: s 342(1)(r) and (s) of the Act. The Magistrate referred to the circumstances of the motor vehicle collision. She referred to his personal circumstances. She took into account his previous good record and his early plea. She referred to general deterrence.
41. It is clear from the Magistrate's sentencing remarks she was of the view that the question of general deterrence was important for offences of this kind. There can be no doubt that she was right to proceed upon that basis, notwithstanding the appellant's youthfulness (R v Slattery (1996) 90 A Crim R 519) and notwithstanding his mental problems (R v Leach (2003) 85 SASR 139).
42. The courts must make it clear to the public generally that it views conduct of this kind seriously. The courts have a duty to ensure that persons who use the highways are not put at risk by persons who would drive like this appellant.
43. We do not accept therefore that the sentencing Magistrate was not entitled to have regard to aspects of general deterrence. We think this case required the sentencing Magistrate to have regard to that matter. However, that is not to say that she was right to accumulate the two sentences.
44. In our opinion, the Magistrate took into account all relevant matters in considering the sentences which are to be imposed. It was a matter for her as to how she ought to weigh those matters in arriving at the sentence to be imposed.
45. In our opinion, there can be no criticism of the manner in which the Magistrate went about her task. She proceeded to sentence in the logical way explained above. Indeed, the appellant's counsel was unable to point to any aspect of her Honour's sentencing remarks which indicated error in the way in which she proceeded.
46. In the end result, the appellant's counsel was forced to say that the Magistrate must have erred in the exercise of her sentencing discretion because both the head sentence and the non-parole period were too high having regard to the matters subjective to the appellant.
47. However, in putting that submission, the appellant's counsel agreed, during argument, that a sentence of 18 months imprisonment was within the appropriate range having regard to the circumstances of the offence and the matters subjective to the appellant. Having made that concession, he was then forced to argue that the Magistrate was wrong to accumulate 12 months of the 18 months sentence of imprisonment imposed upon the second conviction with the first conviction.
48. In the end result, the appeal turned upon whether the Magistrate erred in the exercise of her sentencing discretion by accumulating the two sentences. In developing what was the appellant's final submission, it was contended that the Magistrate placed too much weight on matters of general deterrence.
49. There was only one incident. Unfortunately, in that one incident, two persons suffered injury. That made the appellant guilty of two offences. However, he had to be sentenced having regard to his criminal behaviour. In Attorney-General v Tichy (1982) 30 SASR 84, Wells J said at 92-93:
