46 The defendant submitted that there was a need to assess the level of relative culpability of other entities involved in the incident in January 1999 in determining the appropriate sentence. In this context, it was submitted that the apparent failure to prosecute any other relevant party, the failure to prosecute or continue the prosecution against BMP and the extent of the culpability of other entities were to be taken into account in determining penalty. In relation to a similar submission, Hungerford J in WorkCover Authority of New South Wales (Inspector Carmody) v Consolidated Constructions Pty Ltd (2001) 109 IR 316 stated:
[43] What I think flows from those settled principles as to the sentencing process is that the penalty is to be determined by reference to the offence. It is necessary to make this point because I detected a continuing thread running through the submissions of Mr Phillips that in viewing the total circumstances in assessing criminality one had to consider in a relative or proportionate sense the conduct of the other parties involved. As Mr Phillips said: 'The evidence clearly reveals the involvement of other parties all of whom either caused or contributed to the accident on 15 December 1997.' I am concerned in that that approach focused more on the occurrence of the collapse of the brick wall causing fatal injuries rather than with the offence as charged, and as set out in the particulars thereof, which may be distractive in the sentencing process as to the defendant's failures. There can be no doubt on the admitted evidence that the brick wall was in an unstable state at all relevant times of the defendant's occupancy of the site as the principal contractor. What it was charged with was a failure to ensure persons not in its employment were not exposed to risks to their health and safety; and that, essentially, concerned a failure by it to properly assess the risk posed by the freestanding, but unstable, brick wall. The wall collapsed, it may be said for whatever reason, but that was not the occurrence with which the defendant was charged. This aspect of the immediate reasons for the occurrence of an accident, as distinct from the steps enabling it to occur and with which a defendant stands charged, was considered by a Full Court of the former Industrial Court in Haynes v C I & D Manufacturing Pty Ltd (1994) 60 IR 149 at 158-159 in the following way:
… The general duties created by the OHS Act, such as in ss 15 and 16, are clearly directed, we think, at obviating 'risks' to safety at the workplace; it would therefore be wrong in considering whether an alleged breach of those general duties had been made out in any particular case to reason from the actual occurrence of an accident, even though causing death or injury, as the necessary detriment to safety and as to which a causal connection was to be shown. The accident itself may well, and probably does, manifest the existence of a detriment to safety and will, no doubt, be some measure of the degree of severity of the detriment; but, it seems to us, it is to the essential ingredients of the offence charged which one must attend by assessing the objective facts causing the detriment to safety and the casual connection therewith of the employer …"
In making those comments, the Full Court was dealing with the liability of a defendant for a breach of the Occupational Health and Safety Act but, in my view, the same approach needs to be had in mind in considering penalty because, after all, the penalty is fixed for the offence found to have been proven. It is, therefore, to the offence itself to which attention is to be directed and not, as Mr Phillips suggested, the occurrence of the accident and the contribution of other persons for what occurred.
[44] In WorkCover Authority (NSW) (Inspector Twynam-Perkins) v Maine Lighting Pty Ltd (1995) 100 IR 248 at 257, Bauer J helpfully, with respect, put the matter in this way:
Whilst … it was natural to concentrate on the events giving rise to the actual cause of the death, such a concentration exhibits an error in law as was pointed out by the Full Court in the passage from C I & D Engineering previously quoted. The actual event of the accident and injury is relevant; but it goes to satisfy the evidentiary burden that failure gave rise to a risk to health, safety or welfare.
[45] In the present case, then, the collapse of the brick wall causing the death of two workers manifested the existence of a detriment to safety and provided a measure of the degree of its severity.
[46] As to the contribution of other persons for what occurred, so much relied upon by Mr Phillips here to reduce the culpability of the present defendant, I have to say I think counsel overstated the position and in such a way as to invite error in the sentencing process. There can be no doubt, in my view, that in determining the culpability of a defendant the role played by other parties is necessary to be considered as part of a review of the total circumstances of the case. However, it cannot, I think, be used to itself reduce the culpability of a defendant in any sharing or proportionate way of an overall penalty but only as a factor assisting in the determination of the real culpability of the defendant for the offence charged. Mr Phillips put it this way:
You do not need to look at the circumstances of the events to identify what was the proportionality or what is the portion rather of the criminality of a particular co-accused, because if as I said, if we had had the whole range of possible defendants in these proceedings in the one hearing, one perhaps then has that proportionality of perhaps relief, one could perhaps feel it by way of the evidence that in the circumstances here one would have thought the starting point, as I have said in my submissions, is firstly the wall, the wall should not have been in that state at all. It was clearly not meant to be like that … it was perhaps a carport attached to the building where the Blue Mountains Water Company was to be found. The fact of the cutting slab compromised the wall. Then of course you then go to the beginning of the work on that site. We were not the principal contractor, Develco was. Develco had certain responsibilities. That then flows on to van der Meer Bonser Pty Ltd … the dilapidation [report] was commissioned by Develco …
[47] Although Mr Phillips said he was not suggesting that the proper process involved apportioning the total culpability between all of those persons responsible and fixing a penalty as a share therefore for a particular defendant, I think his submission came very close to that and, for that reason, I would wish to state my understanding that that is not what the sentencing process involves in assessing the objective seriousness or the nature and quality of an offence. I think the vice in the approach by Mr Phillips, who clearly used it to support a penalty lower than what it might otherwise be, may be seen from his following submission:
One has to look at the total circumstances in assessing the nature and the quality of the offence to identify how much of the whole incident really was the responsibility of the relevant accused which is before the Court now … In doing that one might say there are players in this whole incident who are more blameworthy than the accused who is before the court and that does require assessment of the total circumstances of the events and in making that assessment one then could form a proper view of the nature and the quality of the offence. To do otherwise might, I think, as the cases say, suggest some form of justifiable grievance in the accused who says: Well, just because I was there and I am the only one left, or I am the only one that WorkCover Authority, for whatever reason, decides to prosecute. One has to still look at the whole circumstances and say, 'What part of the whole circumstances did I play?' True it is, if we had done what we should have done, this accident may not have happened, and I say it may not. If the proper work had been done before in a safe way before we got there, this wall equally may never have fallen.'
[48] It will be therefore apparent, I think, that Mr Phillips' submission was dangerously close to what I have referred to as apportioning a total penalty as between persons said to be responsible for the occurrence of the accident. I am unaware of any such approach in the sentencing process and, I think, it should be stated as plainly as may be that it is an approach leading to error. To the extent that Mr Phillips relied upon the parity principle in sentencing to support such a submission, I am of the view that that principle does not require a sharing or apportionment of culpability (and hence of sentence) but rather is designed to ensure that there should not be a marked disparity between sentences given to co-offenders for the offence for which they have been respectively found guilty …
