In considering the statutory defence under s28(a) of the Act, the court in Inspector Richard Mulder v GRD Minproc Ltd found the offence foreseeable. Therefore, the foreseeability of the offence must be reflected in the defendant's culpability for the offence. The court held at [81]:
The system of mesh, reo-bars and tie-wire chosen to cover the penetrations was shown to be susceptible to force and to slide off the penetrations if any one or more of a number of variables were in place. The system was therefore unsafe. As the penetrations were not properly secured on the day of the incident I find it was reasonably foreseeable a fall could occur. The incident was also foreseeable given the failure to warn the employees, including a young apprentice, of the known risk posed by the penetration, especially a penetration not safely secured. While I have found there was a failure in the inspections to identify the risk was ongoing - a risk existed and continued - I do not accept the failure to properly inspect the penetration covers added to the reasonable foreseeability of the incident. The penetrations were an obvious and continuing risk if not appropriately secured. The quality of the inspections contributed to the breach but not to the foreseeability of the offence. The defendant failed to ensure the method they employed to alleviate this obvious risk was effective. The failure to warn of the risk posed by the penetrations added to the foreseeability of the incident. I find therefore in the circumstances present on the day of the incident it was reasonably foreseeable a person could fall through the penetration. (emphasis added).
16 The defendant submitted given the court has recognised the chosen system could have been safe and as the defendant was not on notice it was unsafe, the offence is not one in which the defendant contumeliously disregarded or ignored a known safety risk. The court has found the risk of a fall through an improperly secured penetration was foreseeable in the circumstances. I accept, however, where there was an endeavour to alleviate the risk through the particular designed system of coverage for the penetration, the risk was not foreseen.
17 The contribution by third parties to the identified risk to safety is relevant to the court's consideration as to the objective seriousness of the offence. The rigor applicable to site safety design and the required inspections was of paramount importance to ensure the safety of the sub-contractors employees. Neither this defendant nor other contractors challenged the limitations in design of the covering chosen to eliminate a known and identified risk. The inspections carried out by the defendant and its sub-contractors only re-enforced the assumption the design was adequate to eliminate the risk and to ensure a safe worksite.
18 Evidence revealed while a design which required the perfect equidistant placement of the bars and correct knotting of the tie-wire was safe, any variation in such placement could cause a movement of the mesh off the penetrations. A cursory glance or a casual kick does not meet the necessary level of caution required of an inspection to demonstrate whether the covering of a penetration was safe. On the day of the incident, under the system chosen by the defendant, there was not a rigorous inspection sufficient to recognise the lack of security over the penetration in Fan Room No. 1.
19 The activities of third parties at the site therefore did contribute to the defendant's breach of the Act. A sub-contractor has been convicted and sentenced for failing to ensure a safe worksite for its employees under s8(1) of the Act (see Inspector Richard Mulder v Axis Metal Roofing Pty Ltd [2008] NSWIRComm 28). Additionally, another contractor who acted in the capacity of the defendant's Construction Manager and the company through which his services were hired and for which he was a director, have also each been convicted of a breach of the Act (see Inspector Richard Mulder v Process Engineering Group Pty Ltd and Anor [2008] NSWIRComm 36). The actions or omissions of these parties in failing to properly inspect the worksite contributed to the risk to safety if not to the foreseeability of the offence (see Inspector Richard Mulder v GRD Minproc Ltd at [80]). As such, there is mitigation to the objective seriousness of this defendant's breach of the Act. (As to contribution see also the Full Bench in Lyco Industries Pty Limited v WorkCover Authority of (NSW) (Inspector Buggy) (2006) 159 IR 82 at [26] approving WorkCover Authority of New South Wales (Inspector Ankucic) v McDonald's Australia Limited & Anor (2000) 95 IR 383 at [103]).
20 A level of deterrence must be factored into the consideration as to penalty. The principles relevant to deterrence were recited by the Full Bench in Capral Aluminium Limited v WorkCover Authority of NSW (2000) 49 NSWLR 610 at [74] where it was said:
. . . the . . . Court should take in relation to the question of deterrence, both general and personal or specific, when sentencing an offender in relation to a serious breach of the legislation. It follows that both aspects of deterrence are matters which should normally be given weight of some substance in the sentencing process; and although there may be exceptional cases (see, for example, Page v Walco Hoist Rentals Pty Limited (No. 2) [2000] NSWIRComm 39 at [40]-[43]) we would expect such cases to be very rare . . .
21 The defendant company still operates in the industry so an element of specific deterrence is relevant. The defendant had a commitment to site safety both before and after the incident as evidenced by its comprehensive safety system. The system now requires continual review and updating. Senior management personnel are contributors to the various designs chosen for site safety and there is engagement of specialist occupational, health and safety officers since 2002 (as opined by Mr Henderson, currently GRD Minproc's Group Manager, Construction and Health, Safety and Environment. The defendant has an appropriate focus on occupational, health and safety. Given the court's acknowledgment of the defendant's pre-existing site safety system now reviewed and secure, there is little fear of the company re-offending. The consideration of specific deterrence as an element in penalty is therefore limited.
22 Regarding general deterrence, once again the construction industry must be reminded of the need for the regular and thorough examination of all systems designed for safe working. The obligation to ensure rigorous re-evaluation of the systems chosen for safe working must be emphasised. The requirement to warn employees of identified hazards, especially if among the employees there are vulnerable, young apprentices, is also important to reiterate to the construction industry.
23 In considering subjective factors in mitigation of the offence, the company has existed as a public company since 1981 and has no prior convictions. Since 2002, GRD Minproc and its subsidiaries have been involved in 16 construction projects, including several in Western Australia, one in New Zealand, several in Zambia and other African nations and the United Kingdom.
24 At the time of the incident, the defendant employed or engaged approximately 150 employees and sub-contractors to work at its construction site. At the time of the incident, the defendant and its subsidiary companies employed or engaged 330 employees across Australia and 380 persons worldwide.
25 As at February 2008, the defendant engaged over 600 persons across Australia and with its subsidiaries, over 1050 persons worldwide.
26 The court accepts the defendant took its occupational, health and safety obligations seriously both prior to and after the incident. This was reflected in the defendant's extensive occupational, health and safety system in the form of its HSE Plan which was rigorously enforced upon its contractors. Those contractors complied with the requirements imposed upon them. The court has before it affidavit evidence and a comprehensive collection of documents which record a well planned safe working system.
27 After the incident and before work recommenced, the defendant ensured the penetration covers were welded down to prevent them from being untied or moved. It was a simple step to ensure safety and not costly. The rectification procedure, I accept, ensured site safety.
28 While the defendant entered a plea of not guilty, it also co-operated with the prosecutor in agreeing to the tender of a Statement of Agreed Facts in the defended hearing. Additionally, the defendant conceded it was the employer and the site was a place of work for the defendant. I accept the defendant co-operated with the WorkCover Authority on the day of the incident, including providing documentation to WorkCover to inspectors at that time.
29 The defendant does not have any prior convictions for offences in New South Wales or any other jurisdiction in Australia. The maximum penalty is $550,000.
30 The defendant has a good safety record, given the extensive nature of its operations in Australia and across the world since 1981. The defendant has expressed remorse over the incident, including to Mr Sadik. The defendant contributes significantly to projects beneficial to the community by way of educational scholarships and charitable donations. It is a good corporate citizen.
31 The factual circumstances which gave rise to this prosecution are substantively the same as prosecutions brought against Axis Metal Roofing Pty Ltd (IRC1086 of 2006), Process Engineering Group Pty Ltd (IRC1090 of 2006) and Mark Joseph Griffith (IRC1091 of 2006). A consideration of the respective culpabilities of the prior offenders charged with breaches of the Act arising out of this incident is relevant to ensure the principle of equal justice is applied in consideration as to penalty. Regarding the distinction between parity and consistency, the Full Bench observed Capral at [62]-[63] and [66]:
[62] It is important to observe the distinction between, and the differing application of, the principles of parity and consistency. Consistency is relevant to the sentencing of different offenders with similar characteristics who have committed similar crimes, and to the sentencing of co-offenders in the same crime. The principle of parity is usually considered applicable only to the sentencing of co-offenders in the same crime and this is not relevant in this matter....
[63] When sentencing or hearing appeals by different offenders, what must be looked at is whether the sentence is within the range appropriate to the objective gravity of the particular offence and to the subjective circumstances of the particular offender, and not whether it is more severe or more lenient than some other sentence (other than that of a co-offender) which merely forms part of that range: see R v Morgan (1993) 70 A Crim R 368 where Hunt CJ at CL said (at 371):
"It is quite wrong to compare the sentence under challenge directly with that imposed upon another offender (who is not a co-offender) simply because the two offenders may have similar characteristics and may have committed similar crimes. What must be looked at is whether the challenged sentence is within the range appropriate to the objective gravity of the particular offence and to the subjective circumstances of the particular offender, and not whether it is more severe or more lenient than some other sentence (other than that of a co-offender) which merely forms part of that range. As Mason J said in Lowe v The Queen (1984) 154 CLR 606 at 612:
'The reference to an appropriate sentence is apt to be misunderstood. Generally speaking, a sentence within a limited range of years is appropriate to the circumstances in which the offence was committed and to the character, antecedents and conditions of the offender. As the ascertainment and imposition of an appropriate sentence involve the exercise of judicial discretion based on an assessment of various factors it is not possible to say that a sentence of a particular duration is the only correct or appropriate penalty to the exclusion of any other penalty.' "
. . .
[66] The principle of consistency is relevant to this appeal, as it is a reflection of the notion of equal justice, a fundamental element in any rational and fair system of criminal justice: see, for example, R v Henry (1999) 46 NSWLR 346 at 353 where Spigelman CJ said:
"12. As I indicated in Jurisic , the purpose of a guideline judgment is to foster consistency in sentencing. The importance of consistency was well expressed by Mason J in Lowe v The Queen (1984) 154 CLR 606 at 610 - 611:
'Just as consistency in punishment - a reflection of the notion of equal justice - is a fundamental element in any rational and fair system of criminal justice, so inconsistency in punishment, because it is regarded as a badge of unfairness and unequal treatment under the law, is calculated to lead to an erosion of public confidence in the integrity of the administration of justice.'
