56 As the law presently stands, there is a rational, logical and cohesive hierarchy of offences concerned with the infliction of death or serious injury by the use of a motor vehicle. The offences range from negligent driving causing grievous bodily harm (s 42(1)(b) of the Road Transport (Safety and Traffic Management) Act with a maximum penalty of 9 months imprisonment) through the driving offences in the Crimes Act to manslaughter by gross criminal negligence. All of these offences involve varying degrees of negligence, however the actual conduct may be described, ranging from a lack of care and proceeding through dangerousness to culpable negligence: R v Buttsworth [1983] 1 NSWLR 658. This structure is acknowledged by s 52AA(4) that provides that on a trial for an offence of manslaughter or an offence under s 53 or s 54 a jury can return a verdict of guilty of an offence under s 52A. It is also seen in s 52A(6), a provision that prevents a person being convicted of both manslaughter and an offence under s 52A arising from the same facts."
108 As noted in R v Borkowski at [56], the location of manslaughter above a s.52A offence in the hierarchy of offences is demonstrated by s.52AA(4) concerning alternative verdicts:
"(4) Alternative verdicts
If on the trial of a person who is indicted for murder or manslaughter or for an offence under section 53 or 54 the jury is satisfied that the person is guilty of an offence under section 52A, it may find the accused guilty of the offence under section 52A, and the accused is liable to punishment accordingly."
109 There is a further unusual feature about the offence of manslaughter. Historically, there has been a statutory qualification concerning the penalty for manslaughter. A maximum penalty was prescribed and, until 1974, other periods of imprisonment were specified in the relevant section. Further, a proviso has existed, and continues to exist, which permits a Judge to discharge the jury (giving rise to an acquittal) if a nominal punishment was sufficient in the circumstances.
110 As enacted in the Crimes Act 1900, s.24 provided:
"24. Whosoever commits the crime of manslaughter shall be liable to penal servitude for life, or for any term not less than three years, or to imprisonment for any term not exceeding three years:
Provided that, in any case, if the Judge is of opinion that, having regard to all the circumstances, a nominal punishment would be sufficient, he may discharge the jury from giving any verdict, and such discharge shall operate as an acquittal."
111 In an article entitled "Manslaughter by Negligent Act or Omission" (1958) 31 ALJ 630 at 636, Mr HA Snelling QC observed that the NSW legislature (in s.24) had "recognized that in some circumstances manslaughter may merit no punishment".
112 The 1973 Report of the Criminal Law Committee on Proposed Amendments to Criminal Law and Procedure, chaired by his Honour Judge Amsberg, recommended amendment to s.24 concerning punishment for manslaughter:
"We recommend that section 24 provide simply that the punishment for manslaughter be penal servitude for life - subject, of course, to reduction under section 442. The words of section 24 recommended for omission appear to us to have no practical effect other than to confuse the reader. We suspect that they are an unintended survival from the days before section 442 was amended, in 1924, to create the same effect as the words under attack."
113 As a result, s.24 was amended by the Crimes and Other Acts (Amendment) Act 1974 to provide as follows:
"24. Whosoever commits the crime of manslaughter shall be liable to penal servitude for life.
Provided that, in any case, if the Judge is of opinion that, having regard to all the circumstances, a nominal punishment would be sufficient, he may discharge the jury from giving any verdict, and such discharge shall operate as an acquittal."
114 Section 24 was amended again by the Crimes (Life Sentences) Amendment Act 1989, which made a series of amendments (to ss.24, 26, 27, 28 and 29) as part of the "truth in sentencing" statutory regime, whereby a maximum penalty of life imprisonment was replaced by a maximum penalty of imprisonment for 25 years. Since 1989, s.24 has been in the following terms:
"24 Manslaughter - punishment
Whosoever commits the crime of manslaughter shall be liable to imprisonment for 25 years:
Provided that, in any case, if the Judge is of the opinion that, having regard to all the circumstances, a nominal punishment would be sufficient, the Judge may discharge the jury from giving any verdict, and such discharge shall operate as an acquittal."
115 The Hon Mervyn Finlay QC, in his "Review of the Law of Manslaughter in New South Wales" (April 2003, paragraph 6.4, page 26), observed that the "extreme range of moral culpability for the offence of manslaughter is acknowledged by the legislature" in s.24 of the Act in its present form.
116 In R v Forbes (2005) 160 A Crim R 1, Spigelman CJ at 27 [133]-[134] observed that "manslaughter is almost unique in its protean character as an offence. … In its objective gravity it may vary, as has been pointed out, from a joke gone wrong to facts just short of murder".
117 In cases of motor vehicle manslaughter, it has been said to be unproductive to consider, in a manslaughter case, what might have been the appropriate sentence for an offence of aggravated dangerous driving occasioning death: R v Cameron (2005) 157 A Crim R 70 at 75 [26]. Manslaughter has been described as a "markedly more serious offence" than a s.52A offence: R v Cramp (1999) 110 A Crim R 198 at 220 [108]; R v Cameron at 75-76 [28].
118 Thus, both statutory provisions and relevant authorities point to a hierarchy of offences with manslaughter located above aggravated dangerous driving causing death under s.52A. Despite the unusual features surrounding the offence of manslaughter, it should be treated as a more serious offence for the purpose of the principle in The Queen v De Simoni.
