Publication restriction: Nil
On 19 September 2022, Mr Cameron Wells, a labourer employed by Young Mining Company Pty Ltd (YMC) was working at a Thuddungra mine operated by YMC (the mine). He was using a shovel to clean mud off the tail drum of a Powerscreen Chieftain 2100X 3 Deck Incline Screen (Mobile Screen). He placed the shovel against the tail drum while it was rotating at speed. The tail drum caught the shovel causing it to be pulled into the conveyor rollers. Mr Wells yanked his hands off the shovel to prevent his hands and arms from being pulled into the conveyor belt along with the shovel. In doing so, Mr Wells sustained serious injuries to his left hand, being degloving of the thumb and tip amputation of the ring finger.
The NSW Resources Regulator (the Regulator) prosecutes YMC in proceedings 2024/324576, alleging that YMC, being a person conducting a business or undertaking (PCBU) who had a health and safety duty under s 19(1) of the Work Health and Safety Act 2011 (NSW) (WHS Act) to ensure so far as is reasonably practicable the health and safety of workers while the workers are at work in the business or undertaking, failed to comply with that duty and the failure to comply with the duty exposed workers including Mitchell Coupland and Mr Wells, to a risk of death or serious injury contrary to s 32 of the WHS Act.
The Regulator also prosecutes Mr Aditya Jhunjhunwala in proceedings 2024/324514 alleging a breach of Mr Jhunjhunwala’s duty under s 27(1) of the WHS Act. The Regulator alleges that Mr Jhunjhunwala failed to exercise due diligence to ensure that YMC complied with its duty under s 19(1) of the WHS Act because he failed to take reasonable steps to ensure that YMC had complied with that duty and his failure to comply with his s 27(1) duty exposed workers including Mr Coupland and Mr Wells, to a risk of death or serious injury.
For the reasons which follow, I am satisfied beyond reasonable doubt that YMC failed to take the reasonably practicable steps to ensure the health and safety of Mr Coupland and Mr Wells, particularised at paragraphs 19(d), (e), (f) and (h) of the Second Further Amended Summons and in so doing, exposed Mr Coupland and Mr Wells to a risk of death or serious injury. It follows that I find YMC guilty of the s 32 offence.
However, for the reasons which follow, I am not satisfied that the prosecutor has established that Mr Jhunjhunwala committed a Category 2 offence in that he failed to comply with his duty under s 27(1) of the WHS Act to exercise due diligence by taking the measures pleaded in 20(a)-(d) of the Further Amended Summons to ensure that YMC complied with its duty or obligation under s 19(1) of the WHS Act, thereby exposing Mr Coupland and Mr Wells to a risk of death or serious injury. It follows that I find Mr Jhunjhunwala not guilty of that offence.
On 2 September 2024, the Court issued three summonses as follows:
2024/324609 – Proceedings against YMC alleging a Category 1 offence with a Category 2 offence charged in the alternative;
2024/324576 – Proceedings against YMC alleging a Category 2 offence; and
2024/324514 – Proceedings against Mr Jhunjhunwala alleging a Category 2 offence.
On 4 August 2025, the prosecutor filed Amended Summonses in Court in all three matters. A Further Amended Summons was filed in each matter on 22 September 2025. On 17 November 2025, the Category 1 charge against YMC in proceedings 2024/324609 was withdrawn by the prosecutor and dismissed. On 9 December 2025, leave was granted for the Prosecutor to file a Second Further Amended Summons in matter 2024/324576 which consolidated the Category 2 charges into a single charge. Proceedings 2024/324609 was withdrawn and dismissed.
The joint trial of both defendants commenced on 8 December 2025 and concluded on 15 December 2025, when judgment was reserved.
This Court sits as both the tribunal of fact and law.
The prosecution must prove each of the elements of the offence beyond reasonable doubt. In the event that the prosecution has failed to discharge its burden to the requisite criminal standard, a verdict of not guilty must be returned and the defendant acquitted.
The decision of the tribunal of fact is to be based on the evidence, not suspicion, nor speculation. When assessing the evidence, the trier of fact may use common sense and experience in order to assess the credibility of each witness. It is within the Court’s power to accept some part of a witness’s evidence while rejecting other parts.
I must bring an open and unbiased mind to the evidence and view it clinically and dispassionately and not let emotion enter into the decision making process. I must then deliver my verdict according to the evidence.
“The risk was the risk of workers, including Mr Coupland and Mr Wells, suffering death or serious injury as a result of being entangled in, or holding an item that became entangled in, or crushed by moving parts of the Mobile Screen while cleaning the Mobile Screen (the Risk).”
Paragraph 19 of Annexure A to the Summons pleaded 11 measures, each of which is alleged to have been reasonably practicable, to eliminate (or alternatively minimise, if it is not reasonably practicable to eliminate) the pleaded risk. At the outset of the trial, counsel for the Regulator abandoned particular 19(b).
Paragraph 19 pleaded as follows:
“19. The defendant failed to ensure, so far as is reasonably practicable, the health and safety of workers, in that it failed to take one or more of the following measures, each of which is alleged to have been reasonably practicable to eliminate, or alternatively minimise, if not reasonably practicable to eliminate, the Risk:
(a) Adequately maintaining the skirting rubbers on all conveyor belts of the Mobile Screen;
(b) [Abandoned];
(c) Prohibiting the operation of the Mobile Screen to screen material;
(i) During wet weather;
(ii) When the material was wet;
(d) Developing, implementing and enforcing a written safe work procedure for cleaning the Mobile Screen, including to clear any build-up of mud or material in the Mobile Screen, which specified: (1) the Mobile Screen to be isolated; and (2) the Mobile Screen was to be relocated to a concrete hardstand or pad (if required); and (3) a high pressure hose was to be used to clean the conveyor belts and/or other tools, such as a shovel, to remove built-up mud or material;
(e) Implementing and enforcing its “Standard Operating Procedure – Isolation” dated 27 October 2017 (the Isolation Procedure) which specified that (1) prior to commencing any cleaning of the Mobile Screen, the machinery should be stopped, shutdown and locked out and (2) workers were to notify a supervisor or Quarry Manager when they were to isolate plant in accordance with the Isolation Procedure;
(f) Providing workers with isolation locks to be used for isolating plant, in accordance with the Isolation Procedure;
(g) Implementing a maintenance program for the Mobile Screen that included a maintenance strategy, frequency of inspections, original manufacturer recommendations, removal of built-up mud or material, belt tracking and which was undertaken by a competent person such as a maintenance technician;
(h) Undertaking an adequate risk assessment for clearing built-up of mud in the Mobile Screen which identified all reasonably foreseeable hazards, assessed the Risk arising from the identified hazards and resulted in the implementation of adequate controls;
(i) Appointing a nominated competent person, who had acquired through training, qualification or experience the knowledge and skills to carry out the task of supervising mining operations at a mine, to perform the function of quarry manager;
(j) Providing training, information and instruction (or adequate training, information and instruction) to workers on:
(i) the Mobile Screen’s product User Manual Operation and Maintenance;
(ii) A safe work procedure for clearing a build-up of mud in the Mobile Screen that required the Mobile Screen to be isolated and use of fit for purpose tools, such as a high-pressure hose;
(iii) the Isolation Procedure;
(iv) The “Standard Operating Procedure – Mobile Screen” dated 3 January 2022 (the Mobile Screen Procedure);
(k) Implementing and enforcing the Mobile Screen Procedure which specified that the Mobile Screen only be operated by trained, competent, reliable and authorised personnel; and the Mobile Screen was not to be operated without guards in place and secured.”
A person commits a Category 2 offence if:
(a) the person has a health and safety duty, and
(b) the person fails to comply with that duty, and
(c) the failure exposes an individual to a risk of death or serious injury or illness.
Element 1 YMC had a health and safety duty under s 19(1);
Element 2 YMC failed to comply with its duty; and
Element 3 The failure by YMC to comply with its health and safety duty exposed an individual to a risk of death or serious injury.
This offence of three elements is consistent with the decision of the Court of Criminal Appeal in Grasso Consulting Engineers Pty Ltd v SafeWork NSW; Grasso v SafeWork NSW [2021] NSWCCA 288 at [3] per Simpson J and in many decisions of the District Court of NSW. [1]
However, there are a number of decisions of both the Court of Criminal Appeal [2] and the District Court [3] which endorse four elements for this offence as follows:
Element 1 The defendant was conducting a business or undertaking.
Element 2 The defendant owed a health and safety duty to ensure, so far as was reasonably practicable, the health and safety of:
workers engaged by it or workers whose activities are influenced or directed by the defendant;
while the workers were at work in the business or undertaking.
Element 3 The defendant failed to comply with its health and safety duty.
Element 4 The failure exposed an individual to a risk of death or serious injury.
There is no substantive difference between the two approaches. Rather, the approach which adopts four elements divides element one of the three element approach into two elements. For the purposes of this matter, I will adopt the three element approach to the offence, consistent with the manner in which the trial was run. I note that such an approach is not consistent with my decisions in SafeWork NSW v Tattam Express Pty Ltd [2025] NSWIC 7 and SafeWork NSW v E.J. & D. Hammond Pty Ltd [2026] NSWIC 5. While the approach adopting four elements perhaps involves a greater level of precision, the fact that the defendant is a PCBU is rarely, if ever, challenged.
The ‘Object’ clause in s 3 of the WHS Act provides:
(1) The main object of this Act is to provide for a balanced and nationally consistent framework to secure the health and safety of workers and work places by:
(a) protecting workers and other persons against harm to their health, safety and welfare through the elimination or minimisation of risks arising from work or from specified types of substances or plant, and
…
(h) maintaining and strengthening the national harmonisation of laws relating to work health and safety and to facilitate a consistent national approach to work health and safety in this jurisdiction.
(2) In furthering subsection (1)(a), regard must be had to the principle that workers and other persons should be given the highest level of protection against harm to their health, safety and welfare from hazards and risks arising from work or from specified types of substances or plant as is reasonably practicable.
The offence is one of strict liability: s 12A of the WHS Act.
The content of the primary duty of care is set out in s 19 of the WHS Act which provides:
(1) A person conducting a business or undertaking must ensure, so far as is reasonably practicable, the health and safety of:
(a) workers engaged, or caused to be engaged by the person, and
(b) workers whose activities in carrying out work are influenced or directed by the person,
while the workers are at work in the business or undertaking.
(2) A person conducting a business or undertaking must ensure, so far as is reasonably practicable, that the health and safety of other persons is not put at risk from work carried out as part of the conduct of the business or undertaking.
(3) Without limiting subsections (1) and (2), a person conducting a business or undertaking must ensure, so far as is reasonably practicable:
(a) the provision and maintenance of a work environment without risks to health and safety, and
…
(c) the provision and maintenance of safe systems of work, and
(d) the safe use, handling, and storage of plant, structures and substances, and
…
(f) the provision of any information, training, instruction or supervision that is necessary to protect all persons from risks to their health and safety arising from work carried out as part of the conduct of the business or undertaking, and
(g) that the health of workers and the conditions at the workplace are monitored for the purpose of preventing illness or injury of workers arising from the conduct of the business or undertaking.
A person is a worker if the person carries out work in any capacity for a person conducting a business or undertaking, including work as:
(a) an employee, or
(b) a contractor or subcontractor, or
(c) an employee of a contractor or subcontractor…
(1) More than one person can concurrently have the same duty.
(2) Each duty holder must comply with that duty to the standard required by this Act even if another duty holder has the same duty.
(3) If more than one person has a duty for the same matter, each person:
(a) retains responsibility for the person’s duty in relation to the matter, and
(b) must discharge the person’s duty to the extent to which the person has the capacity to influence and control the matter or would have had that capacity but for an agreement or arrangement purporting to limit or remove that capacity.
A duty imposed on a person to ensure health and safety requires the person:
(a) to eliminate risks to health and safety, so far as is reasonably practicable, and
(b) if it is not reasonably practicable to eliminate risks to health and safety, to minimise those risks so far as is reasonably practicable.
The word “risk” is not defined in the WHS Act. Risk should not be interpreted in a complicated fashion. Safety cannot be ensured if a risk is present. The presence of a risk to the health or safety of a worker constitutes a breach of s 19 of the WHS Act. It is not necessary that there be a particular accident, or that a person is actually injured. What is required is the creation of the risk. The relevant risk for the commission of the s 32 offence is a risk of death or serious injury: s 32(c).
The prosecution bears the onus of proving as an element of the offence that at the time of the offence it was reasonably practicable to ensure the health and safety of the persons alleged to be at risk. The risk should be identified with sufficient precision to determine if it was reasonably practicable to eliminate the risk, or if not, if it was reasonably practicable to minimise it. In this way the application of reasonable practicability may arise more than once.
“Reasonably practicable” is defined in s 18 of the WHS Act which provides:
In this Act, reasonably practicable, in relation to a duty to ensure health and safety, means that which is, or was at a particular time, reasonably able to be done in relation to ensuring health and safety, taking into account and weighing up all the relevant matters including:
(a) the likelihood of the risk concerned occurring, and
(b) the degree of harm that might result from the risk, and
(c) what the defendant knows, or ought reasonably to know, about;
(i) the hazard or the risk, and
(ii) ways of eliminating or minimising the risk, and
(d) the availability and suitability of ways to eliminate or minimise the risk, and
(e) after assessing the extent of the risk and the available ways of eliminating or minimising the risk, the cost associated with available ways of eliminating or minimising the risk, including whether the cost is grossly disproportionate to the risk.
The state of knowledge applied to the definition of reasonably practicable is objective. It is that possessed by persons generally who are engaged in the relevant field of activity and not the actual knowledge of a specific defendant in particular circumstances: Laing O*’*Rourke (BMC) Pty Ltd v Kirwin [2011] WASCA 117 at [33].
The reasonably practicable requirement applies to matters which are within the power of the defendant to control, supervise and manage: Slivak v Lurgi (Australia) Pty Ltd (2001) 205 CLR 304; [2001] HCA 6 at [37] per Gleeson CJ, Gummow and Hayne JJ (Slivak).
The s 19 duty requires knowledge of the risk emanating from the activities of the defendant: Slivak. Foreseeability of the risk to persons from the activity is an element of this question of knowledge. It would not generally be practicable to take measures to guard against a risk to safety that was not reasonably foreseeable: Genner Constructions Pty Ltd v WorkCover Authority of New South Wales (2001) 110 IR 57; [2001] NSWIRComm 267 at [68].
The words “reasonably practicable” indicate that the duty does not require a defendant to take every possible step that could be taken. The steps to be taken in the performance of the duty are those that are reasonably practicable for the employer to achieve the provision of and maintenance of a safe working environment. Bare demonstration that a step might have had some effect on the safety of a working environment does not, without more, demonstrate a breach of the duty: Baiada Poultry Pty Limited v The Queen (2012) 246 CLR 92; [2012] HCA 13 at [15], [38] per French CJ, Gummow, Hayne and Crennan JJ.
An employer must have a proactive approach to safety issues. The question is not, did the employer envisage a particular danger, but rather should it have*:* WorkCover Authority of New South Wales v Kellogg (Aust) Pty Ltd [1999] NSWIRComm 453.
A defendant must have regard not only for the ideal worker but also for one who is careless, inattentive or inadvertent: Dunlop Rubber Australia Ltd v Buckley (1952) 87 CLR 313; [1952] HCA 72 at [320] per Dixon CJ. If there is a foreseeable risk of injury arising from the employee’s negligence in carrying out his or her duties, then this is a factor which the employer must take into account: Smith v Broken Hill Pty Ltd (1957) 97 CLR 337; [1957] HCA 34 at [343]. It may not always be possible to foresee various acts of inadvertence by a worker, but defendants must conduct operations on the basis that such acts will occur, and they must be guarded against, to the fullest extent practicable.
The prosecution must prove that the act or omission of the defendant was a significant or substantial cause of the worker being exposed to the risk of injury: Bulga Underground Operations v Nash (2016) 93 NSWLR 338; [2016] NSWCCA 37 at [127] (Bulga Underground).
The question is to be determined by the application of common sense to the facts, bearing in mind that the purpose of the inquiry is to attribute legal responsibility in a criminal matter: Royall v The Queen (1991) 172 CLR 378; [1991] HCA 27.
Regard must be had to the scope and objects of the Act: Simpson Design and Associates Pty Ltd v Industrial Court of New South Wales (2011) A Crim R 340; [2011] NSWCA 316 at [79]-[102]. The relevant question is not whether the particularised failures of the defendant were the cause of the death or injury, but rather whether there was a causal relationship between the act or omission and the risk to which a worker was exposed: Bulga Underground at [130].
Regard must also be had to the manner in which the charges are framed. The Court must consider whether the duty holder’s acts or omissions caused the risk as pleaded in the particular circumstances at a particular time when a person is exposed to the risk: Saunders Civilbuild Pty Ltd v SafeWork NSW [2023] NSWCCA 261 at [174].
The prosecutor tendered a large number of exhibits during the course of the hearing:
Photographs of the Mobile Screen taken by various persons, several of which were marked up by witnesses during the course of the trial;

Manufacturer documentation concerning the Mobile Screen;
Mobile Screen’s Product User Manual, Standard Operating Procedures (SOPs), Risk Assessments, Safe Work Method Statements (SWMSs), pre-start records and timesheets for the Mobile Screen;
Guidance material;
Communications to YMC employees in response to the incident;
Regulatory Notices issued by the Regulator and responses;
Statements from Mr Coupland, Mr Wells and Mr Rick Price;
Updated safety documentation produced in response to the incident;

YMC documentation relating to its investigation of the incident;
YMC maintenance checklists, service, breakdown and machinery defect records and associated correspondence;
Porter Equipment Australia Pty Ltd (Porter Equipment) Invoices;
Documentation concerning the appointment of Mr Rick Price as the Nominated Competent Person for YMC; and
Statement of Agreed Facts.
The prosecution called five witnesses. The first witness, injured YMC worker Mr Wells, gave evidence about his employment with the related company Causmag Ore Company Pty Ltd (Causmag), the circumstances which led to his move to the mine and his role at the mine from the time of his commencement on 1 September 2022. Mr Wells gave evidence about the people with whom he worked, the operating procedures that were in place and the training that he received. He also gave evidence about the operation of the Mobile Screen, the problems with it clogging up, the process for cleaning it, and the incident which occurred on 19 September 2022. Finally, he gave evidence about his interaction with Mr Jhunjhunwala and other manager at the mine, Mr Bipin Pandey.
The second witness, Mr Richard Price (Rick Price), a contractor to YMC, gave evidence about his history working as a self employed contractor driving a truck for YMC and his transition to his role as the operator of the Mobile Screen. He gave evidence about the training he received and the safety documentation in use at the mine. Mr Rick Price gave evidence about the other people working at the mine at various points and how his role transitioned over that time. He also gave evidence about the history of mud problems with the Mobile Screen and the process for cleaning it. Finally, he gave evidence about the incident involving Mr Wells and the actions taken by YMC after it occurred.
The third witness, former YMC employee Mr Mitchell Coupland, gave evidence about his work at the mine from May 2022, including his induction process and the personnel with whom he worked.
The fourth witness, casual YMC employee Mr Wayne Price, gave evidence about his engagement at the mine from April 2022 to July 2022 to review the maintenance paperwork and machinery on behalf of the Mine Manager, Mr John Mills and the process by which he was inducted onto the mine. Mr Wayne Price also gave evidence about the maintenance work that he did on the machines on site, including the Mobile Screen and the induction process for Mr Coupland.
The last witness, YMC employee Mr Mills, gave evidence about his employment with YMC as Acting Quarry Manager and site manager from January 2022 to April 2022. He gave evidence about the other people working at the mine during that period, as well as the documented safety systems and processes in place. He also gave evidence about operating the Mobile Screen, the problems caused by the wet material and the manner in which the Mobile Screen was cleaned to address them. He gave evidence of his interactions with Mr Jhunjhunwala on that subject.
It is an agreed fact that, at all material times, YMC was the owner and “mine operator” of the mine, as defined in s 7A of the Work Health and Safety (Mines and Petroleum Sites) Act 2013 (NSW). It is also an agreed fact that the mine was a “workplace” as defined by s 8 of the WHS Act. I am therefore satisfied beyond reasonable doubt that YMC was a person conducting a business or undertaking (PCBU) as defined in s 5 of the WHS Act so it had a work health and safety duty prescribed by s 19(1) of the WHS Act to its workers as defined in s 7 of the WHS Act.
Exhibit EE was an offer of casual employment by YMC to Mr Coupland which he accepted on 31 May 2022. Therefore, I find that Mr Coupland was a worker of YMC, as defined in s 7 of the WHS Act.
Exhibit 2 was an offer of casual employment by YMC to Mr Wells which he accepted on 14 July 2022. Therefore, I find that Mr Wells was a worker of YMC, as defined in s 7 of the WHS Act.
While it was not expressly conceded, YMC did not contest the fact that Element 1 of the offence could be established, and I find that the prosecutor has proved this element of the offence beyond reasonable doubt.
The risk posed by unguarded and poorly maintained machinery is well known in the industry. What YMC knew, or ought reasonably to have known about the pleaded risk and ways of eliminating or minimising it may be established by reference to its pre-incident documented systems of work and the available industry guidance material (Exhibit B).
The SafeWork NSW Code of Practice: How to m**anage w**ork h**ealth and s**afety r**isks, August 2019 relevantly provided information on how to conduct a risk assessment and stated that control measures need to be adjusted when working with new or modified equipment or processes. It further stipulated that control measures need to be supported by the development of a safe work procedure and training of workers in that procedure in a manner that requires them to demonstrate that they are able to perform the work safely.
The SafeWork NSW Code of Practice: Managing the r**isks of p**lant in the w**orkplace, August 2019 relevantly provided that unguarded moving parts of plant are a major cause of work-related death and injury in Australian workplaces, that workers are to be trained by a competent person in how to perform work including maintenance and cleaning work safely, and that ongoing supervision also needs to be in place. It further provided that training of workers should be “hands on” and reinforced by documented safe work procedures which reflect local working conditions, as well as operating manuals and other instructional material provided by the manufacturer.
As to maintenance and cleaning, it provided that plant must be maintained and repaired according to the manufacturer’s specifications and that this should usually occur when the plant is isolated and locked out according to a documented isolation procedure. It further stated that any guards which have been removed for that purpose are to be replaced before the plant is put back into operation.
The NSW Code of Practice*:* Safety management systems in mines, February 2015 provided detailed guidance on developing and implementing a safety management system and controlling risks in the mining environment.
The NSW Code of Practice: Mechanical e**ngineering c**ontrol p**lan, September 2016 (MECP Code) was referenced in YMC’s pre-incident safety system documents, including the Mechanical Engineering Risk Assessment, 19 January 2022. The MECP Code addressed the significant risk of workplace death or injury associated with using plant and associated structures, typically resulting from insufficient control of mechanical energy due to the use of plant that is not fit for the purpose, the absence of safe systems of work or an under skilled workforce. It stated that training and instruction of workers in risk control measures is therefore essential, as is maintenance, to ensure that plant and structures remain safe to operate and that repairs should be identified through an inspection, testing and defect system. It further noted that energy isolation procedures allow for the safe maintenance, inspection or testing of plant and that the removal of guards to carry out maintenance has been a source of workplace incidents.
The Regulator’s Guide*:* Health and safety at quarries, November 2018 stated that tasks such as maintenance, repairs, servicing, clearing blockages and cleaning can be dangerous and that workers can be fatally or seriously injured if the associated risks are not carefully managed. It provided that alternative methods to protect workers from the increased risk of injury from exposure to the accidental release of energy are necessary when guards are removed to perform maintenance tasks. It recommended the use of a lock-out and tag-out procedure to achieve this, underpinned by clear rules on how and when isolation procedures should be implemented. It also noted the paramount importance of a maintenance and inspection program developed in the context of the operating environment to ensure that equipment and machinery is safe to use and a documented training program to ensure that work is performed only by people who are trained and competent or properly supervised.
The Regulator’s Part 1*:* Reference material and information, August 201**8 provided that SWMS (or safe work procedures) should be developed for operating all equipment and machinery, and for other tasks with safety implications and that information should be available about implementing training programs in respect of them.
The Australian*/New Zealand* *Standard AS/NZS 4024.*3610:2015 – Safety of m**achinery – Part 3610: Conveyors–General requirements (the Australian Standard) stated that, historically, most serious or fatal accidents on belt conveyor systems occur during cleaning and maintenance or unsafe access. It therefore required an operational risk assessment to be undertaken, and appropriate risk controls implemented prior to using conveyors. It noted that operational procedures should be developed in accordance with the designer’s recommendations and site-specific environmental conditions and that work should not be permitted in a danger zone while the conveyor is running. Instead, it stated that the procedure for such work should include a documented system of energy isolation and dissipation for each conveyor, which incorporates both a locking and tagging or permit system and a verification process to ensure that energy isolation has occurred, particularly where such work requires the isolation of guards. Training of personnel which incorporates assessment of competence was also stipulated as essential, as was a maintenance program to ensure that the conveyors remain fit for purpose.
Prior to the incident YMC had a documented safety management system (SMS) for the mine which included a Mechanical Engineering Risk Assessment dated 19 January 2022 (Mechanical Engineering RA) (Exhibit PP77). The Mechanical Engineering RA, which listed Mr Jhunjhunwala as part of the Workplace Risk Assessment Team, addressed the risks associated with the operation and maintenance of all plant and equipment at the mine. One of its key focus areas was the “Operation of Mobile Plant”, including the Mobile Screen in respect of which it identified the following hazards:
“Incident due to untrained, inexperienced, or otherwise unsuitable operational personnel; Incident caused by poor housekeeping and/or poor preventative maintenance... Incident caused by poor guarding or isolation measures. E.g. injury due to exposed pinch points and/or moving parts…”.
“Source Operating Manuals…Staff and contractors are trained and certified for operation of the new mobile plant, and; Preventative Maintenance Schedule is developed, followed and checked, and; Housekeeping is prioritized over production to minimize unscheduled maintenance shuts and/or risks to personnel, and; OEM machine guarding is maintained…”.
Another key focus area of the Mechanical Engineering RA was “Maintenance and Inspection of Mobile Plant”, in respect of which it identified the hazard of an “[i]ncident due to uncontrolled operation/movement of plant or plant components due to: [f]ailure to notify other staff of the maintenance event, or [f]ailure to immobilise and secure the mobile plant, and [f]ailure to display signs or prevent accidental access by others to the maintenance area... [and] [i]njury due to unqualified and/or inexperienced staff. E.g., incorrect techniques or use of tools.”
The associated control measures included:
“Source Maintenance Manuals and develop a Maintenance SOP, including: Checklist, requiring acknowledgement from relevant personnel on-site, of the maintenance event, and Isolation schedule and checklist, (including the use of padlocks and interlocks), and Display signs alerting others to maintenance event,... [and] Ensure that only suitable qualified and experienced personnel are permitted to undertake specific maintenance tasks...”
Exhibit ZZ91 was another version of the Mechanical Engineering RA, also dated 19 January 2022. This version identified hazards associated with conveyors including “person caught/trapped” and “poor isolation procedure, person caught when conveyor start up.” Controls included “Guarding”, “Supervision” and “Competent operators.”
The YMC SMS also included the Mechanical Engineering Principal Control Plan, dated January 2022 (Mechanical Engineering PCP) (Exhibit PP78). It was authorised by Mr Jhunjhunwala and provided a documented framework to maintain the safety of equipment, including during maintenance activities, and was intended to provide a systematic means to maintain and manage mechanical plant. It identified mechanical risks as including contact with moving or rotating plant, access to mechanical plant and structures and inadequate energy dissipation and isolation.
In respect of “Maintenance, Repair, and Cleaning” the Mechanical Engineering PCP provided that “YMC will maintain and repair equipment in line with the OEM’s recommendations. Where there is no OEM’s recommendation YMC will endeavour to carryout maintenance and repairs in line with mining industry practices.” In respect of the “Safe Operation of Conveyors” the Mechanical Engineering PCP provided:
“Operation and maintenance must be undertaken by competent personnel, in line with the site maintenance regime, and appropriate systematic approach to risk control and management. This includes maintenance of guards, safety critical systems, monitoring and alarm/warning systems.”
In respect of “Isolation” the Mechanical Engineering PCP referred to the “Young Mining Company Isolation Procedure”.
The Mechanical Engineering PCP also required mechanical SOPs be developed and contained within a Document Register to assist mechanical staff in carrying out specific tasks for critical jobs to ensure safety and consistency of approach. In respect of “Competence” the Mechanical Engineering PCP required workers who conduct mechanical work to be qualified tradespersons or otherwise assessed as competent. The Quarry Manager was required to conduct training and assessment in relation to plant use and maintenance, which incorporated both a written and practical component and to maintain records of such training. Working on site without having completed a site induction was prohibited.
YMC had documented SOPs for the Mobile Screen dated 20 January 2022 (First Mobile Screen SOP) (Exhibit ZZ95) and 3 February 2022 (Exhibit ZZ94) (Second Mobile Screen SOP), both of which were SOP #029 but which appear to have been prepared independently of each other and both of which were said by YMC to be current as at 19 September 2022. Each required operators to obtain a Certificate of Competence prior to operating the Mobile Screen. Neither procedure identified the risk of entanglement or addressed the task of cleaning the Mobile Screen. The January 2022 Mobile Screen SOP expressly provided that “[o]nly trained, competent, reliable, and authorized personnel should operate or maintain this machine” to prevent [d]amage to equipment, injury to personnel, death” and identified “[c]ompetency based training” as the control measure to address this high-risk activity. It mandated pre-start checks to address the risks of damage to the Mobile Screen or its attachments, including because of incorrect operation. It required faults or issues to be recorded in pre-start book and reported to the Quarry Manager and guards to be in place when the machine was in operation. Indeed, it contained an express warning about the need to use guards:
“Always make sure that all safety guards are installed and in correct working order before operating this machine.”
YMC had also developed a Mobile Screen Operations Trainer Guide dated February 2022 (Exhibit ZZ101). The Trainer Guide stated that its purpose was to ensure people who are required to operate the Mobile Screen had the knowledge and skills required to be able to do so competently and included a written assessment to be completed by workers.
YMC had a documented Standard Operating Procedure – Isolation dated 27 October 2017 (Isolation SOP) (Exhibit ZZ54), the object of which was to *“*ensure Total Isolation of both Plant and Machinery; that correct isolation is established before commencing any maintenance, repair, installation, service and cleaning of plant.” The procedure required the use of isolation locks and danger tags to be used in conjunction with personal locks. It required the isolation of the Mobile Screen in specified circumstances and included photographic instruction of how to do this. A worker was required to attach their personal lock to the isolation point prior to commencing maintenance work on any equipment. The Isolation SOP included a Questionnaire to be completed by workers.
YMC also had a Trainer’s Guide for Risk Assessments and Job Safety Analysis (JSA) dated November 2017 (Exhibit ZZ53) (the Guide). The purpose of the Guide was to provide all personnel with the skills and competencies required to identify when to prepare a JSA, how to identify the steps, hazards and risks, rate the hazards and identify appropriate and adequate controls.
Finally, YMC had a Health and Safety Handbook 2017 (the Safety Handbook), which set out information on risk assessment and control as well as JSAs and SOPs (Exhibit D). It required all plant to be stopped, isolated and tagged before guards were removed and provided that machine guards must not be removed or made inoperative except by authorised personnel, then only for the purpose of carrying out repairs or adjustments. It expressly prohibited the operation of any plant without guards in place, except in the event of a guard failure during operation. This was reiterated specifically in relation to conveyor belts:
“NEVER start a conveyor with the guards off – they are there for your protection.”
The prosecutor submitted that a risk assessment was not conducted for any work which took place between 19 March 2022 and 19 September 2022 and that Mr Wells, Mr Coupland and Mr Rick Price received training in that regard only after the incident. The prosecutor pointed to the actions taken by YMC after the incident which demonstrate that a risk assessment for cleaning the Mobile Screen was a reasonably practicable measure to address the pleaded risk. It noted that a SWMS (Exhibit OO24) was partially completed and that it was unclear whether it was in place at the time of the incident.
YMC contended that there was no evidence about what a risk assessment should have contained or what fell within the description of “all reasonably foreseeable hazards”. YMC contended that the prosecution had therefore failed to prove this particular.
YMC was unable to produce any risk assessments for the period 19 March 2022 to 19 September 2022 in response to a s 155 Notice issued by the Regulator (Exhibit ZZ48). YMC’s response to such a request was:
“We could not find relevant records for the period mentioned above at the site. There have been frequent changes at the site after the retirement of Kevin Davidson who was there for approx. 40 years. We are still trying to find out and making enquiries in this regard.”
The risk assessments which occurred in the six-month period immediately preceding the incident appear to be confined to the daily pre-start checks of plant and machinery. That broader risk assessments were not conducted during that period is consistent with the evidence of Mr Coupland that he had not done one prior to the incident (T200.4) and Mr Rick Price’s evidence that he had not seen a risk assessment matrix until after the incident (T130.12-20). Similarly, Mr Wells stated that he never participated in a risk assessment in relation to the cleaning of the Mobile Screen (T52.41) and that YMC did not provide him with any training in how to conduct a risk assessment (T37.22). Mr Wells also gave evidence that although he was told that a JSA should be conducted every day, that did not occur, he had never conducted one, and he could not recall seeing another worker conduct one (T38.29-43). Mr Rick Price also gave evidence that he had not seen a JSA at the mine or filled one out prior to the incident (T128.38-43).
A risk assessment would have identified risk of entanglement in moving parts of Mobile Screen and the necessity to isolate it and lock it out before cleaning it and replacing guards before turning it back on. So much is demonstrated by the risk assessment which YMC conducted on 9 November 2022 which addressed the obvious risk of injury or amputation when cleaning belts and rollers (Exhibit 0023). I am satisfied beyond reasonable doubt that, prior to the incident, no risk assessment concerning cleaning mud off the Mobile Screen was conducted.
That such a measure was reasonably practicable was demonstrated by the above risk assessment as well as a risk assessment in relation to Mobile Screen cleaning conducted on 26 October 2022 that identified a high-risk of “pinch points” and “crushing” and stated that the appropriate control measures were to use a guard and isolate the machine (Exhibit NN). Similarly, Mr Rick Price gave evidence of filling out a JSA Worksheet (Exhibit V) after the incident which provided that the Mobile Screen had to be locked out before any cleaning of mud from the rollers could take place (T128.34-T130.3). I am therefore satisfied beyond reasonable doubt that YMC was in breach of its WHS Act duty when it did not undertake an adequate risk assessment for cleaning built-up mud in the Mobile Screen which identified all reasonably foreseeable hazards and implemented adequate controls.
The prosecutor submitted that YMC’s pre-incident Mechanical Engineering PCP identified the need to develop SOPs to assist mechanical staff in carrying out specific tasks for critical jobs. The prosecutor noted that this was consistent with the requirements of the guidance material. The prosecutor then submitted that despite this, prior to the incident there was no documented procedure for cleaning the Mobile Screen, with the possible exception of the SWMS marked with a “Revised Date” of 29 September 2022 (Exhibit OO24). The prosecutor noted that both the First Mobile Screen SOP and the Second Mobile Screen SOP did not address cleaning of the Mobile Screen. Similarly, the Isolation SOP was a general procedure for isolating all plant at YMC before commencing any maintenance, repair, installation, service and cleaning.
The prosecutor pointed to the evidence from each of Mr Rick Price (T120.45), Mr Coupland (T212.21-28) and Mr Wells (T52.31-37) that they had not been shown how to clean the Mobile Screen, prior to the incident.
The prosecutor also relied on the evidence that, prior to the incident, the Mobile Screen’s Product User Manual (User Manual) (Exhibit QQ) set out a process for cleaning the conveyor belts using a high-pressure hose (p 311) and noted that this was consistent with the SOP produced by the supplier of the Mobile Screen, Lincom Pacific Equipment Pty Ltd (Lincom) (Exhibit ZZ39). The prosecutor pointed to the evidence in YMC’s response to the s 155 Notice served on it (p 5, Q14), that YMC had a water truck available at the mine and a high-pressure hose that could have been used to clean the conveyor belts.
The prosecutor pointed to Mr Coupland’s evidence that, following the incident, he cleaned the Mobile Screen using a high-pressure hose and “it worked really well” (T247.43-T248.27). The prosecutor accepted that there was evidence from Mr Rick Price that attempting to clean the Mobile Screen with water made the problem worse (T157.32-39) and that this was consistent with YMC’s evidence that the water truck has been used on prior occasions to wash down the Mobile Screen prior to servicing but that it was “never used to wash mud from the screen while the screen was operating in the field as water and mud do not mix and there will be a far bigger risk in terms of safety at ground level. Water truck was used to wash screen down before servicing on concrete pad not clay” (p 5 Q15). However, this was said to be immaterial given the pleading that if, for whatever reason, a high-pressure hose was unable to be used, other tools such as shovels could be used once the Mobile Screen was isolated and locked out.
YMC submitted that this particular is misguided as it does not address the process to retrack the belt. YMC relied on the evidence of witnesses that the key would be removed from the Mobile Screen when undertaking cleaning or maintenance (T116.41-42; T121.19-22; T122.1-6). YMC further pointed to the evidence that the Mobile Screen was trammed away from the area where it had been operating onto a pad where it was then cleaned. In that regard, YMC relied on the following evidence from Mr Wells (T83.25-T84.13):
Q. Okay, thank you for clarifying that. Then, when it was to be relocated, someone made a pad?
A. Yeah, Rick or Mitch.
Q. Do you recall how they did that?
A. Yeah, with the front‑end loader.
Q. Yes, so what do you do?
A. What do I do?
Q. When you make a pad to sit this machine on?
A. Sorry. Sorry, so they put a pad down to - so that way they can build a ramp to go up - so with that way, we’ve got a way of loading into the grizzly. So, there’s a pack—
Q. You’ve got to put some material on the ground?
A. Yes.
Q. Some rock on the ground?
A. Yep.
Q. You pad it down with the bucket of a front‑end loader?
A. Yeah, get it - get it level so we can level the machine up to it. And then, build a ramp to go off into the grizzly.
Q. Yes, and part of the reason that that’s done is so that you don’t end up having to work in boggy soil?
A. Yes.
Q. It’s elevated a bit?
A. Yes.
Q. Because over time with the rain, it does get boggy around there and you’ve got to move it to a new pad?
A. Yes.
Q. And that’s what was happening that day?
A. Yes.
Q. Thank you. Part of moving it, as well, as when it’s being moved, do you observe that material would fall off it? Clay would fall off it and it would help to clean it. Do you remember that?
A. Parts of it, yeah.
Q. Parts of it?
A. Fall off the tracks mainly.
Q. Yes. And you never moved the mobile--
A. No.
Q. --screen?
A. No.
Q. And you were never authorised to move it?
A. No.
YMC’s submissions fail to address the fact that the measure deals with developing, implementing and enforcing a written safe work procedure for cleaning the Mobile Screen.
Exhibit OO24 is a SWMS which deals with cleaning the Mobile Screen and adjusting the belts. It requires workers to isolate, tag out and “test to dead” the Mobile Screen. It shows a “Revised Date” of 29 September 2022. There is no evidence of when that document was first created but Exhibit OO18 appears to be an earlier version of the same document, which stated that workers should isolate and tag out the plant. I cannot exclude the possibility that this document existed prior to the incident. However, it does not provide any instruction on the tools to be used to clean the Mobile Screen, stating only “use correct tools/Fit for [purpose]”. Further, it is apparent from the evidence of each of Mr Rick Price, Mr Coupland or Mr Wells to which I have already referred, together with Mr Rick Price’s evidence that he and Mr Coupland worked out a process for cleaning the Mobile Screen (T120.48-49; T123.43) that none of them were aware of it prior to the incident. Therefore, even accepting that this document existed at the time of the incident, it fell short of being a safe work procedure for cleaning the Mobile Screen and it was not implemented or enforced.
If the procedure set out in the User Manual referred to above were to be considered a documented safe work procedure for cleaning the Mobile Screen, it was not a procedure developed by YMC. Further, it is clear from the evidence from Mr Rick Price about the difficulties of using a high-pressure hose and YMC’s response to the s 155 Notice, consistent with that view, that the procedure was not implemented or enforced. That the procedure in the User Manual was not implemented or enforced is also consistent with Mr Rick Price’s evidence that he and Mr Coupland developed the procedure for cleaning the Mobile Screen.
Exhibit V, referred to above, is a JSA Worksheet which sets out an eight-step process for cleaning mud from the rollers of the Mobile Screen. Mr Rick Price gave evidence that he had never seen, let alone filled out a JSA at the mine before the afternoon of 19 September 2022. His account was that he and Mr Coupland filled out this document after they “found the JSA folder and worked out how to fill it in” (T128.34-T129.14) Mr Rick Price further stated that he and Mr Coupland filled out the JSA Worksheet by looking at past examples of JSAs in the JSA folder (T129.34-T130.1).
The existence of this document, together with the procedures for cleaning the Mobile Screen developed in October 2022 and November 2022 (Exhibit OO23) demonstrate the reasonable practicability of this measure. Further, as pointed out by the prosecutor, the Australian Standard requires site specific operational procedures to be developed based on the designer’s operational procedures and site-specific environmental conditions.
The need for the machine to be operating to track the belt is immaterial to whether or not this measure can be established, because the machine could be turned on for that purpose and then isolated again if further cleaning were required. As YMC noted in the context of the previous measure, this is what Mr Coupland said that he was doing when the incident occurred. Nor does the evidence that tramming the Mobile Screen resulted in the removal of much of the mud build-up assist YMC. In any event, the evidence was that most of the mud removed by tramming was from the tracks of the Mobile Screen, not from the rollers or the tail drum. I am therefore satisfied beyond reasonable doubt that YMC was in breach of its WHS Act duty in that the procedure that it used to clean the Mobile Screen was not committed to writing and those procedures for cleaning the Mobile Screen that were committed to writing were not implemented or enforced.
The prosecutor submitted that workers were not provided with the Isolation SOP, which requires a lock to be attached to the main isolator once the Mobile Screen has been shut down. The prosecutor further contended that the pleaded risk was not minimised as far as reasonably practicable unless the isolation and lock-out was performed to eliminate the risk of inadvertent start up.
YMC accepted that the evidence suggests that no training was undertaken in the Isolation SOP. However, YMC noted the existence of the First Mobile Screen SOP. YMC pointed to the fact that that procedure includes undertaking pre-start checks and staying clear of the Mobile Screen while it is in operation and that both these measures were well known to workers operating the Mobile Screen.
Further, YMC pointed to the fact that the workers knew how to isolate the machine and routinely did so by somebody taking the key out of the ignition and putting it in their pocket. I have referred to the relevant evidence above. This was said to be a reasonably practicable measure for isolating the machine. YMC also relied on Mr Rick Price’s evidence that isolation tags would on occasion be applied to the Mobile Screen when it was cleaned (T134.42-T135.20):
Q. I appreciate you weren’t given any locks, but before Cameron’s accident, was there ever any discussion with anyone about the use of locks?
A. No. There was only tags.
Q. And what were those tags?
A. Isolation tags.
Q. And did you ever have cause to use them?
A. We put one on a couple of times when we were cleaning it.
Q. Cleaning what?
A. The screen machine.
Q. And where would you place the tag?
A. We hang that where the key is or on the isolation switch.
Q. And would the key be there when you hung it?
A. The key was in my pocket.
Q. So, you go through the process you’ve described, of taking the key out, putting it in your pocket, and putting a tag on?
A. Put a tag on the machine.
Q. Did you do that on every occasion or some of the times?
A. Virtually every time we cleaned it.
Q. Virtually every time, is that in relation to the tag, or taking the key out, or both?
A. Tag and key.
Q. Is the battery box the rectangular green-coloured structure in the bottom right-hand corner of the image?
A. Yes.
Q. Is above that the, what do you call it, the lockout?
A. Isolation switch.
Q. Isolation switch?
A. Yeah.
Q. How did you come to know that was the isolation switch?
A. If anything went - we had to - that was meant to be turned off each night to save the battery. But if anything went too wrong then it was meant to be locked. Like, if anything went wrong with the machine.
Q. But you had actually stopped the mobile screen from operating before - from working before, hadn’t you?
A. Yeah, hit the emergency stop button….
Q. Hit the emergency stop button?
A. Hit the emergency stop button.
Q. Yes, and what would that do?
A. It would shut the whole machine down.
Q. Yes, and then someone else would need to reset the machine if it was to start up again?
A. Yes, you’ve got to then dislodge the emergency stop button and then restart the key.
Q. Yes. So, in that way, you did know how to actually turn the machine off?
A. With the emergency stop button, yes.
Q. Yes, and unless someone reset the emergency stop and turned it back on, it wasn’t just going to start up again?
A. No.
Q. And that was why you were isolated?
A. Yes.
Q. If you needed to turn it off?
A. If I needed to, yes.
Q. Because there would be times when you’d need to turn it off to access certain parts of the machine?
A. Yes.
Q. Yes, and you’d use the emergency stop to isolate it?
A. Well, yeah, it just shuts out the whole machine, yeah.
Q. How do you deal with the problem of the screens blocking up?
A. It’s a man handled job with the - you know, you have to obviously isolate the machine and get inside and clean it out by hand. There’s no other particular way of cleaning that.
Q. In terms of isolation, how did you go about that?
A. Well, there’s an isolation switch with a lock-out above the battery on the machine itself.
Q. When you did that task, was it locked out or was the isolation switch turned off?
A. Yeah, no, it’s completely locked out. There’s no power going to any of the--
Q. Was there an isolation lock placed on the isolation switch to--
A. Yes. Yes.
Q. Did you ever use an implement to scrape mud off it?
A. After wash it down we use screwdrivers and jimmy bars and that to dislodge rock, yes.
Q. At any point when you were doing that, was the screen on?
A. No.
I accept Mr Mills’ evidence that isolation locks were used to clean the Mobile Screen when he was working at the mine. However, he ceased employment with YMC in April 2022. Mr Wells’ evidence was that, in the approximately three-week period when he was working at the mine, he had never seen locks applied to the isolation switch on the Mobile Screen (T36.39-48). Consistent with that evidence is his evidence that he had never seen a document which set out when and how to isolate the Mobile Screen (T37.1-7). Further, when it came to cleaning the Mobile Screen, which was a daily task (T45.43), Mr Wells stated that the machine would be turned off but the key would not be removed from the ignition (T44.49-T45.12). By that stage, Mr Rick Price was largely assigned to other duties (T103.24 & 48). Mr Coupland was operating the Mobile Screen (T103.32), assisted by Mr Wells (T123.25-30).
Mr Coupland did not recall having ever seen a documented procedure for isolation of the plant at YMC (T199.18). His evidence was that he had not been trained in how to isolate the Mobile Screen or been issued with an isolation lock for that purpose (T199.29-34). He further stated that he had never seen anyone else use an isolation lock to lock-out the Mobile Screen (T199.38). He gave evidence that he had been provided with isolation tags but had never seen them used (T199.40-46).
I accept Mr Rick Price’s evidence about the use of isolation tags on some occasions when cleaning the Mobile Screen in view of his evidence both that tags were used “a couple of times” and “virtually every time” that the cleaning occurred. His evidence that, prior to the incident, the mine had not issued him with any locks, and that he had never used a lock on any of the machinery (T134.9-14), was consistent with the evidence of both Mr Coupland and Mr Wells. Like Mr Coupland and Mr Wells, he had never seen a documented process or procedure for cleaning the Mobile Screen before the incident (T120.45). Therefore, consistent with his recollection (T147.44) and his evidence that he and Mr Coupland worked out a process for cleaning the Mobile Screen, to which I have already referred, I am satisfied that Mr Rick Price had not seen the Isolation SOP.
After the incident both Mr Rick Price and Mr Coupland were trained in the Isolation SOP and completed the attached questionnaire (Exhibit X). Mr Coupland stated that he underwent training on the Isolation SOP after the incident (T245.27 & 35-37) and was issued with an isolation lock to enable him to comply with it (T246.5-12). Mr Rick Price and Mr Coupland undertook this training in addition to training in the First Mobile Screen SOP, on which YMC relies (Exhibit ZZ59). As noted above, neither the First Mobile Screen SOP, nor the Second Mobile Screen SOP address the cleaning of the Mobile Screen. Accordingly, the fact of their existence does not answer YMC’s failure to implement and enforce the Isolation SOP, which was expressly intended to address the cleaning of plant, among other things. The training of workers in the Isolation SOP and its implementation after the incident demonstrate that the implementation of the Isolation SOP, in addition to the First Mobile Screen SOP, was a reasonably practicable measure for YMC to implement to ensure the health and safety of its workers. Indeed, it was necessary to isolate the Mobile Screen during cleaning in order to eliminate the risk of health and safety to workers so far as is reasonably practicable. I am therefore satisfied beyond reasonable doubt that YMC was in breach of its WHS Act duty when it did not implement and enforce its Isolation SOP or provide locks to workers to enable them to comply with it.
The prosecutor pointed to the existence of the Mobile Screen SOP together with the evidence that workers had not seen it. In particular, the prosecutor relied on Mr Coupland’s evidence that he had been shown how to operate the Mobile Screen by Mr Rick Price. Similarly, the prosecutor relied on Mr Wells’ evidence that he learnt how the Mobile Screen operated by watching Mr Rick Price and Mr Coupland use it (T28.3-8) and that he was not trained in the use and operation of the Mobile Screen with reference to any documented procedure (T28.37).
The prosecutor also pointed to the evidence from Mr Coupland (T212.4-6) and Mr Rick Price (T142.2-12) setting out different procedures for tracking the belt and Mr Coupland’s evidence that he had not been trained in that task and instead relied on his prior experience (T212.30-40). Finally, the prosecutor also relied on evidence that it was a routine practice to operate the Mobile Screen without the guard in place and secured in order to clean the main drum and the rollers more generally (T73.11-33; T74.7-14), and for that purpose Mr Wells used shovels, bolts and other items to attempt to remove built up mud and material from the rollers.
YMC pointed to the evidence of Mr Rick Price’s significant experience and skill using a mobile screening plant (T152.28-49; T169:48-T170.19):
Q. Before in other - in another life you’d operated a mobile screen before?
A. Yes.
Q. And when you came on and you did the induction for joining Young Mining Company - I’m not going to take you through these documents that you went through for hours yesterday - that induction didn’t include an induction in relation to the power screen, and the reason for that was you were already competent and extremely experienced with power screen operation?
A. That’s correct.
Q. When it came to front‑end loaders you’d been operating front‑end loaders for donkey’s years as well?
A. That’s correct.
Q. Yes. So the reality was, in terms - sorry, let me just complete that thought. There was no other quarrying activity of any kind going on at the site during the time you were there?
A. That is correct.
Q. So the only work that was being done was operation of the power screen, housekeeping of the power screen—
A. Yes.
…
Q. And again, you have operated mobile screens prior to coming into YMC for how long, do you think?
A. On and off for 30 years.
Q. Yeah,... (not transcribable)... earthmoving?
A. That’s right, I worked part‑time for him.
Q. They had mobile screens?
A. No, he hired a mobile screen.
Q. Okay, but in any event, was a mobile screen there?
A. Yes.
Q. You knew how to operate it?
A. Yes.
Q. You’d worked with one for the whole 30 years, 20 years, how long do you reckon?
A. On and off for the 30 years.
Q. Yes, and the basic design of mobile screens is pretty much the same?
A. Yes.
Q. When you worked with Mr Coupland you would direct him what to do?
A. We worked as a buddy system. If I couldn’t see him and he couldn’t see me, we didn’t work, because there was only two of us on site.
Q. And you knew that was an important thing to do because of your RFS training as well?
A. Yes, because you’re in a dangerous environment.
Q. So from time to time you’d tell Mitch what to do?
A. Advise, yes.
Q. But you’d give him direction because you were running the screen and--
A. I was training him to become me, more or less.
Q. And again, given your time with the RFS, you were comfortable to train him?
A. Yes.
Q. Because you, as Mr Glissan has gone through, you had a really good familiarity with the type of machinery you were working with?
A. Yes.
Q. Even if you had to use the water truck because of your other training with the RFS?
A. Yes.
Q. Over time you got to observe the way that Mitch worked?
A. Yes.
Q. Is it fair to say that you didn’t really have any concerns about him following your directions? So if you showed him how to do something and you watched him do it, that you were pretty comfortable he’d do it the way you taught him?
A. Yes.
Q. In other words, it wasn’t really like - you watched him for several months and he wouldn’t go off script?
A. No. No. He - he was pretty particular about the way he operated.
Q. Not to harp on about it but you’re pretty good at watching someone in the field do something that he’d been shown to do and see if they’re going to continue doing it because of your significant experience with the RFS?
A. That’s correct.
Finally, YMC pointed to the fact that the Mobile Screen was not running on the day of the incident and that there was no intention to run product on that day (T123.10-11).
In fact, Mr Coupland’s evidence was that he was shown how to operate the Mobile Screen by either Mr Rick Price or Mr Wayne Price (T192.18-31; T197.11-18) but it was nonetheless clear from his evidence that he had not seen the either the First or Second Mobile Screen SOP (T190.10). This was also plainly the case for Mr Wells (T28.37) and Mr Rick Price (T100.35-36). In addition, I find that Mr Wells was not trained, competent and reliable to operate the Mobile Screen, noting his evidence that this was not his role (T24.19-20; T28.24-33) and that he never touched the controls (T68.16-24). Further, while I am satisfied on the balance of probabilities that both Mr Rick Price and Mr Coupland were competent to operate the Mobile Screen, I accept Mr Wells’ evidence that he routinely cleaned the main drum by placing some kind of implement against it while it was rotating, or by using an implement to push the scraper against it while it was turning and that the only way that he could effectively clean the rollers was if they were moving. That process necessarily required operating the Mobile Screen without the guards in place. I am therefore satisfied beyond reasonable doubt that YMC failed in its WHS Act duty to workers when it failed to implement and enforce the Mobile Screen SOP.
The prosecutor submitted that there were serious deficiencies in the training and induction provided to workers. In that regard, the prosecutor pointed to the evidence of various workers concerning the training that they received. Mr Wells’ evidence was that the only induction that he received when he commenced working at the mine was being given paperwork to sign and being shown around the mine site by Mr Rick Price (T23.24-34). Mr Wells also stated that they were given paperwork to read on rainy days, but he could not recall having ever seen the Safety Handbook (T23.40-49).
Similarly, Mr Coupland’s evidence was that he was given a “semi-induction” in the office where he “got shown a few things and they were giving out some paperwork to fill out” (T184.16-27). Mr Coupland further stated that a number of items marked off as completed in his record of induction (Exhibit R) did not in fact occur, such as being guided through the Safety Handbook (T187.11-13) and sitting in presentations on the list of presentation topics that were marked as having been completed (T189.12-15). Mr Rick Price also stated that no presentations occurred during his induction process and that he was just given books to read (T99.43-45). Mr Rick Price also gave evidence that he was aware of paperwork at the mine but that he was never shown what was in the folders in the office and that he and Mr Coupland were never shown proper procedures (T96.31-44).
The prosecutor pointed to the cleaning procedure for the Mobile Screen at p 21-3 of the User Manual, which stipulated that the conveyor belts should be cleaned using a high-pressure hose and that the machine should be switched off and locked out during that process. The prosecutor also pointed to the abundance of the training material which YMC had developed to be used. This included:
The conduct of risk assessments (Exhibit ZZ96);
The conduct of risk assessments and JSAs (Exhibit ZZ97);
Isolation and tagging (Exhibit ZZ98, Exhibit ZZ99, Exhibit ZZ100); and
Mobile Screen Operations Trainer Guide.
The prosecutor also relied on evidence, to which I have already referred, that the workers had not seen either the Isolation SOP or the Mobile Screen SOP. The prosecutor pointed to the training about the procedures particularised as part of this measure provided after the incident to Mr Rick Price (T146.3-34; T147.48-T148.31) and Mr Coupland (T245.27 & 35-46; T246:20), which demonstrated the reasonable practicability of doing so.
YMC submitted that the only evidence before the Court about the content of the User Manual was that it was available to workers and maintenance personnel. YMC also noted the evidence that hoses, shovels and a scraper were available to workers to use as required. YMC accepted that no training was provided to workers concerning the Isolation SOP and relied on its previous submissions that workers nonetheless knew how to isolate the Mobile Screen and in fact did so. Similarly, YMC reiterated its submission that there was insufficient evidence for the Court to be satisfied that training in the Mobile Screen SOP would have eliminated or minimised the risk of death or serious injury.
I am satisfied that workers were not given training on the Isolation SOP and the First or Second Mobile Screen SOP based on the evidence addressed in the context of particular 20(e) (Isolation SOP) and 20(k) (Mobile Screen SOP). I will not repeat that material here. I cannot be satisfied beyond reasonable doubt that workers had not been shown either the SWMS which was in differing forms or the User Manual in the face of clear evidence that the workers would read documentation on wet days, which they were unable to recall at the time of giving evidence. However, I accept that, even if they were given any of those documents to read, what occurred fell short of training and instruction because notwithstanding the content in those documents about a procedure for cleaning the Mobile Screen, the evidence is that Mr Rick Price and Mr Coupland developed a process themselves. I am therefore satisfied beyond reasonable doubt that YMC was in breach of its WHS Act duty in failing to provide the stipulated instruction and training to workers.
The prosecutor submitted that YMC had not made the required nomination to the Regulator and that Mr Rick Price, who was so nominated after the incident (Exhibit Z), did not appreciate what was involved or have experience in mining production and supervising mining works. The prosecutor pointed to the fact that Mr Rick Price was not offered training in that regard and considered that his role did not involve supervising workers (T96.6).
The prosecutor acknowledged the training which Mr Rick Price provided to Mr Coupland but contended that consistent with him not being a supervisor, he did not induct either Mr Wells or Mr Coupland (T105.14) when they started at the mine. Further, the prosecutor pointed to the evidence that Mr Rick Price expressly told Mr Jhunjhunwala that he did not want to be involved in the paperwork and was only there to operate the plant (T93.33-45). The prosecutor accepted that Mr Mills had the necessary skills to perform that role but noted that he only worked at the mine from January 2022 to April 2022 (T292.12-17).
YMC submitted that each part of the quarry operated by Mr Rick Price was within his previous experience and expertise, particularly as there was no extraction of material from the mine taking place when the incident occurred. To make good that submission, YMC pointed to the evidence that Mr Rick Price had significant experience in the use of a Mobile Screen and knew how it operated and that this was the only work going on at the mine in the period leading up to the incident (T152.28-49 & T169.48-T170.19):
Q. Before in other - in another life you’d operated a mobile screen before?
A. Yes.
Q. And when you came on and you did the induction for joining Young Mining Company - I’m not going to take you through these documents that you went through for hours yesterday - that induction didn’t include an induction in relation to the power screen, and the reason for that was you were already competent and extremely experienced with power screen operation?
A. That’s correct.
Q. When it came to front‑end loaders you’d been operating front‑end loaders for donkey’s years as well?
A. That’s correct.
Q. Yes. So the reality was, in terms - sorry, let me just complete that thought. There was no other quarrying activity of any kind going on at the site during the time you were there?
A. That is correct.
Q. So the only work that was being done was operation of the power screen, housekeeping of the power screen—
A. Yes.
…
Q. And again, you have operated mobile screens prior to coming into YMC for how long, do you think?
A. On and off for 30 years.
Q. Yeah,... (not transcribable)... earthmoving?
A. That’s right, I worked part‑time for him.
Q. They had mobile screens?
A. No, he hired a mobile screen.
Q. Okay, but in any event, was a mobile screen there?
A. Yes.
Q. You knew how to operate it?
A. Yes.
Q. You’d worked with one for the whole 30 years, 20 years, how long do you reckon?
A. On and off for the 30 years.
Q. Yes, and the basic design of mobile screens is pretty much the same?
A. Yes.
Q. Right. And as at September 2022, you’ve just said to her Honour you could use up to 18,000 litres and get nowhere. You did have a special knowledge when it came to using water and hoses and high pressure hoses, didn’t you?
A. Yes.
Q. Tell her Honour why?
A. I did 25 years in the fire service, your Honour.
Q. The Rural Fire Service?
A. Yes, that’s correct.
Q. You were a group captain - no, group--
A. Group captain.
Q. How about - I tell you what, instead of me--
A. I started--
Q. --trying to get it right, how about you--
A. Yeah.
…
Q. How about you just - how about you just walk us through it?
A. I’ll explain it even quicker. I started as a troopy, I worked my way up to a captain, then I went to group captain. The group captain is involved in an incident where you control up to 10,000 people.
Q. Right. Up to 10,000 people?
A. Yes. It gets up into a major scene in a major fire.
Q. And you’d been designated a group captain from about 2013, was it?
A. I did 12 years as a group captain.
Q. I’m just going off what the local newspaper in Young records if you Google it?
A. Yes. I did 12 years as a group captain and I think I did 10 years as a captain.
Q. Okay. Now, so that’s a combined total of about 22 years?
A. Plus the previous time in the service.
Q. Sorry. 22 years where you were in charge of various people--
A. Yes.
Q. --in the RFS?
A. Trucks, zones.
Q. All right. Well, this isn’t a question, but thank you for your service; it’s important work especially somewhere like Young. Now, in order to be a captain or a group captain, you’d undertaken certain training with the RFS?
A. That’s correct.
Q. And that training included things like being able to undertake risk assessments?
A. Risk assessments, courses.
Q. Yes. Did you do any courses on how to train other people?
A. Yeah, I did actually. Yes.
Q. What did you do?
A. An RFI. That’s rural fire fighter instructor.
Q. Yes. And how long did that course go for?
A. It’d be a week.
Q. Okay?
A. It was a fair bit.
Q. Yes. And that effectively taught you how to be the teacher for the Rural Fire Service?
A. Yes, that’s correct.
Q. And that was before September 22?
A. Yes, that’s correct.
Q. So when it came to running Cameron Wells through, for example, the front‑end loader operation, you had a lot of experience previously in training people generally?
A. Yes.
Q. And so you were comfortable in training him on the front‑end loader?
A. Yes.
Q. It wasn’t like it was the first time you’ve ever trained someone?
A. No.
I accept Mr Rick Price’s evidence both that he was familiar with the operation of the Mobile Screen and that he was accustomed to supervising and managing large groups of people. However, YMC’s submission ignores the fact that no competent person was in fact appointed as the Quarry Manager on 19 September 2022 as Mr Rick Price was nominated on 22 September 2022. It also fails to have regard to Mr Rick Price’s express evidence that he eschewed any “paperwork” and that he did not see himself as responsible for supervising other workers on the site or managing any necessary paperwork, including in relation to safety matters.
Further, Mr Rick Price’s evidence made it obvious that, even at the time of giving evidence in these proceedings, he did not understand the nature of the role to which he had been appointed (T143.35-38 & T144.23-27):
Q. And you gave some evidence yesterday about being nominated as the competent person for the mine and when that occurred, first of all, what do you understand that concept to mean?
A. It means you have been deemed competent to operate that machine.
…
Q. Do you, now I’ve shown you that document, what’s your understanding of what a person who is a nominated competent person for a mine site, what does that involve?
A. Under my impression, that is a person who is nominated competent to operate that machine.
That Mr Rick Price was not suitably qualified to assume the role of a competent person was also demonstrated by his evidence that, upon finding himself in that position, he contacted retired mining manager, Mr Kevin Davidson and asked him to return to the mine to teach him how to complete the required paperwork (T147.16-34).
I accept that YMC was only screening rock and not conducting any mining (extraction) at the time of the incident. However, that was also the position on 22 September 2022 when Mr Rick Price was nominated to the role. Mr Rick Price accepted that he was responsible for supervising the operation of the Mobile Screen (T95.18-20). However, as he did not see himself as responsible for supervising workers, he did not ensure that they were familiar with YMC’s documented SOPs. This is significant in the context that he was at some point the only person working at the mine with Mr Coupland, until Mr Wells began working, at which point there were only the three of them at the mine on a daily basis.
The appointment of a competent person as Quarry Manager was not only a reasonably practicable measure for YMC – it was a requirement to operate at the site. Having such a person in place would have increased the likelihood that workers were familiar with and adopted the procedure in either the User Manual or the SWMS for cleaning the Mobile Screen, or alternatively that the procedure developed by Mr Rick Price and Mr Coupland was documented and included in Mr Wells’ induction to the mine. I find that YMC failed to meet the measure pleaded at 19(i) and in so doing, was in breach of its WHS Act duty to workers and in particular Mr Wells.
The prosecutor pointed to Mr Wayne Price’s evidence about the maintenance that he would do at the mine. Between May 2022 and 30 June 2022, Mr Wayne Price completed numerous Service Breakdown Records for the Mobile Screen (Exhibit RR). Mr Wayne Price left YMC’s employment on 5 July 2022.
The prosecutor contended that Porter Equipment responded to service requests but did not undertake regular servicing or preventative maintenance, consistent with its response to a s 155 Notice (Exhibit AAA), and that it conducted defect repairs between 14 October 2021 and 7 April 2022. The prosecutor also pointed to the evidence of a series of requests for service made by YMC to Porter Equipment (Exhibit VV) and YMC’s response to a s 155 Notice in which it set out details of a service request made to Porter Equipment on 17 January 2022.
The prosecutor submitted that one of the reasons for build-up of material causing blockages in the Mobile Screen was the failure of YMC to routinely check and replace the skirting rubbers. To establish that proposition, the prosecutor pointed to the defects list created by Mr Wayne Price on 30 June 2022 (Exhibit SS) forming part of the service record for the Mobile Screen which he created on the same date (Exhibit ZZ51) which lists “REPLACE ALL SKIRTING RUBBERS ON ALL BELTS” as an outstanding maintenance item.
As YMC was unable to produce any maintenance records in response to s 155 Notice issued by the Regulator following Mr Wayne Price’s departure, the prosecutor submitted that the Court could infer that no maintenance occurred after that date and therefore the replacement of the skirting rubbers was still outstanding on 19 September 2022.The prosecutor noted the manufacturer’s Dry Screen Range Maintenance Checklist which stated that the skirting rubbers should be replaced after every 250 hours of operation (Exhibit ZZ44). The prosecutor submitted that the Mobile Screen was not maintained and repaired in line with the manufacturer’s recommendations or mining industry practices.
To establish that failure to change the skirting rubbers was a cause of build-up of mud on the Mobile Screen, the prosecutor relied on documentation produced by Lincom, in response to a s 155 Notice. That documentation stated that spillage around a main conveyor drum can be caused by the skirting on the main conveyor, and that this should be fitted tight against the conveyor with no air gaps (Exhibit ZZ38). In a similar vein, Lincom’s response to a question in the Notice (Exhibit ZZ35) about the reasons why mud or other material from building up on the roller of the main conveyor was (Exhibit ZZ36):
“Possible reasons for the spillage are the skirting rubbers on the main conveyor not being replaced or not being hard down on the belt to create the seal that is needed. There are also half moon shaped rubbers on the exit of the feeder that are there to eliminate any spillage.”
Further, in response to a question “6. How can mud or other material be prevented from building up on the roller for the main conveyor belt of the Mobile Screen?” Lincom’s answer was “Preventative Maintenance”. The prosecutor therefore submitted that a system of preventative maintenance would have minimised mud and other material building up on the roller of the main conveyor belt of the Mobile Screen. The prosecutor submitted that both the skirting rubbers on the conveyor belts and the scraper on the tail drum of the main conveyor were damaged and not operating to enable them to effectively remove mud and material from the Mobile Screen. The prosecutor further submitted that the damage to the skirting rubbers on the conveyor belts and the scraper on the tail drum of the main conveyor caused material to spill, build-up and cause blockages to the Mobile Screen. This was said to result in the necessity to clean out the Mobile Screen on a daily basis.
YMC submitted that any required maintenance was carried out in that if an operator raised an issue with the plant, Mr Wayne Price would inspect the machine and either put it back in service or fix it. In that regard, YMC pointed to the evidence of Mr Wayne Price as follows (T289.17-23):
Q. Just excuse me for a moment, Mr Price. Mr Price, you’ve given some evidence about some maintenance that you did including when you took the screen up to the shed. While you were working at the mine, was there preventative maintenance going on with the screen?
A. Preventative? Well, for what I was doing, that was repair plus preventative maintenance, replacing things that had worn before they broke but only where spares were available.
Q. While the screen was up at the shed, I appreciate you did a number of tasks on it, but it had come up there for a particular reason. Do you remember?
A. Trailing belt folded. Had to be replaced.
Q. The trailing belt had to be replaced?
A. Correct.
Q. And did you do that?
A. No, they engaged a specialist from Sydney because it needs to be fitted and vulcanised.
Q. And that took place?
A. Yes.
Q. Is that one of the pre‑start check sheets?
A. That is one of my pre‑start checks. That means, “Operator’s name”, I was operating the screen machine on that day. There’s the start of the engine hours at the top and you’ve got the finish the engine hours at the end of the day. And you go down to your pre‑start and you tick everything down and there’s a problem at the bottom.
Q. We’ll turn to that in a moment. So this is the blank sheet that you get and you’ve got your pen and you’ve filled it out that day so we assume you filled that out on 29 September. Is that right?
A. And that is filled out beside the Chieftain, not in the office. You’ve got to go check it.
Q. So we can see there there’s a number of items listed, guards, tail drums, et cetera?
A. That’s correct.
Q. And then there’s some ticks. What did you do, if anything, in relation to those parts of the plant as part of this pre‑start process?
A. You’ve got to walk around the machine, make sure all the guards are on. Check the tail drums not choked or anything like that. And you do the same with your idlers. It’s just all visual.
Q. If we just scroll down, we can see there’s a “Other Items”, like hydraulic hoses. Is the same process, you’d walk around and have a look and then tick it off?
A. Make sure there’s no leaks, yes. And you’ll see there’s an oil leak noted on the final drive track condition. That’s the drive of the screen machine. That’s only the drive when you move the machine. It was documented there was a slight oil leak in the hub.
Q. And so you’ve recorded on there that there’s an oil leak?
A. Yes.
Q. Then this form went back with you to the office at the end of the shift?
A. Yes.
Q. What was your expectation by writing “oil leak” on there about what would happen?
A. So when I - he arrives in the office, I show him that we’re writing that down and that gets reported to be repaired.
YMC submitted that Mr Wayne Price used the defects sheet and YMC engaged Porter Equipment as required. YMC further submitted that there was no evidence before the Court which addresses adequate maintenance of skirting rubbers on all conveyor belts of the Mobile Screen.
I am satisfied that, at the time of the incident, there was no maintenance strategy in place for the Mobile Screen, beyond the daily pre-start form. Mr Wayne Price’s evidence was that he was engaged by YMC on 5 April 2022 to “sort out the maintenance” (T268.11-12). He further stated that when he commenced working at the mine, the maintenance paperwork was in disarray (T268.20-22). When asked about ongoing maintenance, Mr Wayne Price gave evidence about external maintenance people attending the mine to conduct maintenance (T268.28-32):
Q. In terms of ongoing maintenance of the machines, what did you observe in relation to the systems that were in place about that?
A. Well, you mean ongoing maintenance, well, they had external maintenance people turn up but I wasn’t advised when they were coming. They just turned up.
In its response to a s 155 Notice served upon it, YMC identified the external mechanic which it engaged to do repairs as Porter Equipment, who last serviced the Mobile Screen on 7 April 2022.The invoice issued by Porter Equipment on 27 June 2022 (Exhibit ZZ50) establishes that Porter Equipment conducted servicing of the Mobile Screen, including changing some of the skirting rubbers in October 2021. However, the only work that they had done on the Mobile Screen between October 2021 and 27 June 2022 appears to be to replace a faulty alternator on 7 April 2022. It is difficult to reconcile that evidence with the evidence of Mr Wayne Price that external maintenance people would just turn up, because he only commenced work at the mine on 5 April 2022, two days before the attendance by Porter Equipment to replace the alternator on the Mobile Screen. His evidence gives the impression that external service people turned up at the mine on more than one occasion while he was there. Nonetheless, given YMC’s response to the s 155 Notice served upon it, I am satisfied that Porter Equipment was the only external maintenance company that serviced the Mobile Screen in the period from October 2021 to 19 September 2022.
Accordingly, following the departure of Mr Wayne Price, any maintenance of the Mobile Screen was confined to defects reported on the daily pre-start form. That process was, by definition, one of daily inspection of the Mobile Screen for maintenance issues. However, Mr Coupland’s evidence, which I accept, is that when he was trained in filling out the pre-start form for the Mobile Screen he was told “never to do anything other than tick that first section”, being the high priority faults, because if he failed to so do “the machines would be shut down and we’d be sent home” (T204.46-T205.5). Accordingly, YMC cannot rely upon that process as providing the foundation of a systematic process of inspection and maintenance for the Mobile Screen. Further, such an inspection process was not responsive to manufacturer recommendations concerning the service and replacement of parts.
So far as adequately maintaining the skirting rubbers, I accept that the evidence on which the prosecutor relies establishes that they needed replacing on 30 June 2022 and that this had not occurred by 19 September 2022. I also accept the prosecutor’s submission that the information provided by the supplier, Lincom, shows that failure to appropriately maintain skirting rubbers is a contributing factor to the build-up of mud and material on the roller of the main conveyor. I therefore find that YMC failed to meet the measures pleaded at 19(g) and (a) and in so doing, was in breach of its duty to workers and in particular Mr Wells and Mr Coupland.
Q. So, are you saying that cleaning in that area was required to be undertaken every day?
A. Yes.
Q. And why was that?
A. Because clay was too wet outside.
Q. Okay. What was too wet?
A. The material.
…
Q. You referred to material being too wet, or the - sorry, the material being fed into the feed hopper as being a cause of blockages. That’s right, isn’t it?
A. Yes.
Q. Was there ever any discussion about how the material could be dried out to alleviate these problems?
A. Yeah, we just flip the piles, rotate the piles
…
Q. It was just the machine itself, and it needed cleaning--
A. Yes.
Q. --because of the wet material?
A. Yes.
Q. …So in the months leading up to Cameron’s accident, did you have any issues with operating the screen?
A. Mud. “Wet material”, I should put it down as.
Q. Did you say anything else at the end of that answer?
A. I - I called it as mud but it should be - clearly it’s better as wet material.
Q. Is that wet material that’s coming in from what’s being loaded into the screen, is that right?
A. The - the clay that was in the material, the Causmag, absorbed moisture out of the air, out of the ground. It was like a sponge. It kept absorbing everything and when you put it in the screen machine it was like superglue, it stuck to everything.
Q. When we say stuck to everything, did it stick to the machine itself?
A. Yes.
Q. What impact did that have on the proper running of the machine?
A. It would block the machine in time.
…
Q. Do I take it somebody asked you that question, why is the machine not running?
A. Yes.
Q. Do you remember who that was?
A. I can’t recall who it was but that’s the grounds of the conversation that day.
Q. And you explained the reason why it wasn’t running?
A. Yes.
Q. Had you had conversations with either Mr Jhunjhunwala or Mr Pandey before about this topic of wet material?
A. Yes. Yes.
Q. A few times, many times?
A. Many times. This mud that’s out in this mine, it’s just like a sponge. It just keeps absorbing all the moisture and we’ve tried everything to try and solve the problem.
Q. Mr Coupland, dealing with the period of your employment from April 2022 to September 2022, and in relation to the mobile screen, did you experience any problems with the operation of the mobile screen?
A. In what - what way? Like, what--
Q. In terms of issues associated with the way in which the material was fed and/or processed through the machine?
A. Yes.
Q. And what were those problems?
A. The material when it’s too wet was just causing it to choke up, we’d call it blockages, and material - wet material gets stuck in the belts which in turn will get stuck to the rollers and--
Q. Okay. Dealing with the material being too wet, are you talking about the material that was fed into the--
A. Yes. Yes.
Q. --feed hopper?
A. Yeah.
Q. Okay. And was that the material from the large stockpile situated behind the mobile screen?
A. Correct.
Q. And you referred to the machine blocking up. Were there particular parts of the machine that blocked up?
A. So the actual vibrating screen itself would block up. And then, as I said, the sticky - it’s a lot of clay, so the sticky material would stick to the belt which would then come off and stick to the rollers which would cause the belts to move.
Q. Okay. In terms of belts, do you mean that belts are slipping from wet--
A. They would slide side to side.
Q. Right?
A. The track side to side, I should say, not slide.
Q. Just dealing with the issue that you’ve raised first of the screens and grids blocking up, they’re screens and grids that are located within the body of the--
A. Within the machine itself.
Q. --machine?
A. Yeah.
…
Q. Okay. You mentioned the mud and material affecting the rollers?
A. Yeah.
Q. So do I take it from that at the time there was a requirement to clean the rollers?
A. You’d have to keep an eye on the belts and just make sure the belts didn’t shift over, and if you’ve--
Q. Okay?
A. --noticed the belts starting to move, it meant there was mud sticking to the roller.
Q. Right?
A. So you’d have to clean it off the roller to allow the belt to track back into its‑‑
Q. Okay. When you’re talking about the roller there, are you talking about a particular roller?
A. The tail drums.
Q. Right?
A. Generally. Yeah.
Q. Okay. Is that the tail drums of all of the belts, or just a particular belt?
A. The two that it used to - the one that it happened to most frequently is that fines belt, which is the longer belt out the front, the lower one. It used to happen to that more than anything else.
Q. Right?
A. But it did happen with the - the main feed belt, and also your two side belts.
Q. And when you say it happened the most, are you able to provide an estimate as to the frequency with which that happened from--
A. It would depend on the weather and the material.
Q. Okay?
A. So--
Q. And do I take it by that you mean the wetter it was the more it would happen?
A. Yeah.
Q. In terms of your experience with the plant, were there any problems associated with using that equipment that you encountered during the four months you were there?
A. We had issues with the screen and we damp conditions. The type of material we were trying to screen would block up the screens. The back of the roller drum, which is the feeder belt, would - would move to one side, would track to one side as the material became too wet or too damp, and cause many issues with that type of set up.
Q. The first thing you mentioned was problems with the screens, and you can assume we’ve heard some evidence about this already, Mr Mills, you’re talking about the screens or grids that are kind of interior to the machine, is that correct?
A. Yes, correct.
Q. In terms of those problems, are you able to say with what frequency they arose during your four months of employment?
A. You know, if the material was wet we had problems all the time. Yep, every day we would have a problem if you were trying to screen wet material.
Q. How do you deal with the problem of the screens blocking up?
A. It’s a man handled job with the - you know, you have to obviously isolate the machine and get inside and clean it out by hand. There’s no other particular way of cleaning that.
Q. In terms of isolation, how did you go about that?
A. Well, there’s an isolation switch with a lock-out above the battery on the machine itself.
Q. When you did that task, was it locked out or was the isolation switch turned off?
A. Yeah, no, it’s completely locked out. There’s no power going to any of the--
Q. Was there an isolation lock placed on the isolation switch to--
A. Yes. Yes.
Q. You also mentioned feed belts slipping, I think. Was that your words?
A. Yes, correct.
Q. Was there a particular feed belt that would slip?
A. The back hopper feed belt under wet conditions would track to one side, which causes an overload issue and it would stop the main belt. So - because it would be a load factor issue on that.
Q. So you’re referring to the feed belt that feeds from the hopper into the main belt?
A. Correct.
…
Q. You mentioned problems arising with the machine during wet weather or processing wet material. To your knowledge, was that the cause of the issues associated with the mobile screen blocking up at parts?
A. That’s the major issue, exactly.
Q. Was it wet weather or wet product, or a combination of both?
A. Combination of both. The material absorbs a lot of moisture and a lot of water and it causes big, big problems, how that screen works.
Q. In terms of that problem, was that ever the subject of conversations between yourself and Mr Jhunjhunwala at any point?
A. Yes. Yes. All the time.
…
Q. Yes, if you can just focus on my question, Mr Mills, and try to answer the question that I’m asking. I was asking you about conversations with Mr Jhunjhunwala about wet weather and you agreed with me, I think, that that had been a topic of discussion about not processing during wet weather?
A. Yep.
Q. What was the nature of that conversation? What did you say to him?
A. We’ve got a - well, my comments raised by the down time we had with this machine when the screens get blocked and the tracking problems with the bottom conveyor was not to screen in wet conditions or damp conditions but we had to, because of production. Slowly try and - try and manage as best as we can.
Q. Do I understand from your answer that you have suggested not to screen in wet or damp conditions to Mr Jhunjhunwala? Is that correct?
…
A: Yes, correct.
Q. Well, can I ask you - well, can I just take it back a second, Mr Mills, so I can just understand the nature of the conversations about this topic with Mr Jhunjhunwala?
A. Mm-hmm.
Q. Now, in terms of the wet or damp conditions, to the best of your recollection, what did you say to him about whether the mobile screen should be operated or not during those conditions?
A. Well, my comments were, we shouldn’t operate the screen in wet and damp conditions.
Q. And, to the best of your recollection, did Mr Jhunjhunwala respond to you? What did he say?
A. He said, “We’ve managed it before and you guys have to manage it because it’s been before.”
Q. And what, did the mobile screen after that conversation continue to operate in wet or damp conditions?
A. We did, yes.
Q. But this conversation that you’ve described, did it happen on one occasion or more than one occasion, to the best of your recollection?
A. On more than one occasion.
The prosecutor submitted that if wet material had not been run through the Mobile Screen and that the screening did not take place during wet weather, the need to remove blockages from the Mobile Screen would have been significantly reduced. This was said to provide the causal link to the pleaded risk.
YMC pointed to the evidence of Mr Rick Price, Mr Wells and Mr Coupland that when there was wet weather, work did not occur and that the workers would undertake training on such days. Mr Wells’ evidence that work did not occur on wet days included this (T26.26-35):
Q. And having had a look at that now, does that--
A. Yeah. Yeah, it does.
Q. --refresh your memory?
A. It was a rainy day one that we done. So, when it was too wet to go on site we done paperwork.
Q. Okay. So, it was a rainy day one. What do you mean by that?
A. So, whenever it was too wet to go out on site, that’s when we’d do our forms.
Q. Now, you’ve told the Court that when you went out to Thuddungra to the mine you’d sometimes have wet days, or rainy days?
A. Yeah.
Q. Now, on those rainy days you were generally discouraged from doing work outside, yes?
A. Yes.
Q. Because it would get slippery?
A. Yes.
Q. And it was just generally acknowledged that when it was raining you shouldn’t be outside working?
A. Yes.
Q. And was it the fact that when it was wet you just didn’t operate the machine?
A. It was impossible to operate the machine in the wet.
Q. Yes. So there were days that were down days?
A. Yes.
This was said to be supported by the absence of any evidence that the work which occurred on or around 19 September 2022 took place during wet weather.
Plainly, YMC did not prohibit the screening of wet material. The evidence is overwhelming that it was primarily the screening of wet material which caused the Mobile Screen to clog up, causing the belt to track sideways. YMC relied on the fact that the subparagraphs of 19(c) were not disjunctive, and that while there was evidence of the workers screening material which was wet, there was a significant amount of evidence which supports a finding that such work did not happen in the rain. Accordingly, it was said that the prosecutor cannot establish this particular.
I accept that, on the evidence to which I have already referred, I cannot find beyond reasonable doubt that YMC operated the Mobile Screen in wet weather. In particular, the evidence referring to “wet conditions” could refer to the material being wet, rather than the weather. While I accept Mr Mills evidence that the problems which he encountered included working in wet weather as well as when the material was wet, he no longer worked for YMC at the time of the incident and had not done so for some five months. I note that, in cross-examination, Mr Wells also gave the following evidence (T71.37-50):
Q. Did you use pressure to try and put the scrapers on the machine against the roller for the purpose of cleaning the roller?
A. We tried a couple of times but it just didn’t - we couldn’t get enough pressure to push it over.
Q. All right. So, you said you did this almost every day?
A. Yes.
Q. What if it’s wet?
A. Yes.
Q. And that’s to say those days when it wasn’t so wet you were inside doing paperwork?
A. Yes.
That evidence concerns the operation of the Mobile Screen to clean the rollers rather than to screen material, as pleaded in paragraph 19(c). As noted above, Mr Wells gave evidence in chief about there being occasions where it was “too wet to go out on site” which suggests that, on occasion, the workers went out on site in light or intermittent rain as opposed to steady rain. However, given Mr Wells’ later evidence that working outside was discouraged when wet and Mr Rick Price’s unequivocal evidence that it was “impossible” to operate the Mobile Screen in the wet, I cannot find beyond reasonable doubt that screening of material occurred in the rain.
The subparagraphs of paragraph 19(c) were plainly intended to be read disjunctively. While the word “or” does not appear between the subparagraphs of paragraph 19(c), if that paragraph were not so read, subparagraph (c)(ii) would arguably be redundant because, when working above ground at the mine as they were, the material to be screened would inevitably become wet in wet weather. However, mindful of the decision of the Court of Criminal Appeal in Bulga Underground at [26], and notwithstanding the distinguishing feature in that case in that the subparagraphs of the relevant particular contained entirely distinct measures, I find that this measure is not made out. I am fortified in that view because the prosecutor added the word “or” to the pleaded measure both when opening (MFI 2, p 34) and closing (T336.10-12). It does not appear in the charge as pleaded.
I have therefore found that the prosecutor has established Element 2 of the offence with which YMC is charged in respect of each of the pleaded measures except those in subparagraphs 19(b) and (c) of Annexure A to the Second Further Amended Summons.
The prosecutor contended that a risk assessment would have identified the hazard of entanglement with moving parts of the Mobile Screen and the necessity for the screen to be isolated and locked out before it was cleaned or the guards on it were replaced.
YMC pointed to the evidence that workers who cleaned the machine knew to turn it off by removing the keys before the cleaning took place. YMC emphasised Mr Coupland’s evidence that, on 19 September 2022, he told Mr Wells that he would turn the machine off after tracking the belt and before further cleaning occurred (229.13-23):
Q. Yes, and do you have a distinct recollection of him indicating that was the area which he was going to clean?
A. Yeah, he said to me, he said, “Oh, we’ll get the dirt off in here while we’ve got it open.”
Q. Okay. And then, what did you do?
A. I said to him, “I’ll go and turn the machine off.”
Q. Yes?
A. And I went to walk around the back of the machine to get to the controllers on the other side and that’s when I heard the incident.
The evidence is compelling that what occurred on the day was not a “one off” incident and that it was Mr Wells’ regular practice to clean mud from the drum of the main conveyor of the Mobile Screen by using an implement either to scrape against it while it turned or to use an implement to push the scraper plate against the drum. Not only was Mr Wells in the habit of cleaning the drum in that fashion, Mr Coupland acknowledged in evidence that he had previously seen Mr Wells use an implement to clean the drum while it was turning. (T216.12-13).
A risk assessment would undoubtedly have identified the risk of death or serious injury to workers presented by the hazard of entanglement (either of a person or of an implement held by them) in moving parts of the Mobile Screen. I am also satisfied that the control measures identified to eliminate that risk would have required the plant to be isolated and locked out before any removal of mud from the drum of the main conveyor, or any of the other rollers occurred. Having been expressly identified as a necessary measure to control the specified risk, it is much more likely that a safe work procedure for cleaning the Mobile Screen would have been documented, implemented and enforced and that that safe work procedure would have involved isolation and lock-out of the Mobile Screen. Accordingly, I am satisfied beyond reasonable doubt that YMC’s failure to conduct such a risk assessment was a significant or substantial cause of the exposure of workers, including Mr Wells and Mr Coupland, to the pleaded risk.
The prosecutor contended that implementing and enforcing a written safe work procedure for cleaning the Mobile Screen which specified the above matters was a suitable and available control measure and would have eliminated or minimised the risk, when coupled with appropriate training. YMC submitted that there was a question as to whether the measure pleaded by the prosecutor was causally related to the risk as pleaded but did not elaborate further on that submission.
I accept that YMC had a procedure in place to isolate the Mobile Screen when it was cleaned, because of the evidence that one of the workers would remove the key and put it in their pocket, in the context of there being only two workers present. However, it is also clear that that process was not documented or communicated to Mr Wells. Rather, it is evident that Mr Wells had been routinely removing mud from the drum and the rollers of the main conveyor while the Mobile Screen was operational. It is also clear that Mr Coupland was aware of this occurring on at least one occasion, when Mr Wells used a bolt to clean the tail drum of the main conveyor. I am therefore satisfied beyond reasonable doubt that YMC’s failure to implement and enforce a safe work procedure for cleaning the Mobile Screen, and to document the cleaning process that was in fact in use, was a significant and substantial cause of the exposure of workers, including Mr Wells and Mr Coupland, to the pleaded risk. Had the process developed for cleaning the Mobile Screen been documented, and training in that process provided to Mr Wells, so that a written procedure was developed, implemented and enforced, it is likely that Mr Coupland and Mr Wells would not have been exposed to the pleaded risk and therefore that the incident would not have occurred.
While I accept that there is evidence before the Court which shows that YMC did not have an adequate maintenance program in place for the Mobile Screen and that the skirting rubbers on the conveyor belts were not adequately maintained, there is insufficient evidence for me to find beyond reasonable doubt that the failure to comply with either measure was a significant or substantial cause of exposure of the workers to the pleaded risk. Rather the evidence suggests that the primary cause of build-up of mud or material on the rollers, which led to the necessity for them to be cleaned on a daily basis, was that the material being screened was wet. I am not satisfied beyond reasonable doubt that a properly maintained scraper and skirting rubbers would have eliminated or significantly reduced the need for the mud to be cleaned from the rollers. The prosecutor carries the onus of establishing this. Accordingly, to the extent that the prosecutor relies on these measures, the prosecution must fail.
I have therefore found that the prosecutor has established Element 3 of the offence with which YMC is charged in respect of measures pleaded at subparagraphs 19(h), (d), (e) and (f) of Annexure A to the Second Further Amended Summons.
The prosecutor has proven beyond reasonable doubt the elements of the offence under s 32 of the WHS Act, with respect to measures appearing at 19(h), (d), (e) and (f) of Annexure A to the Second Further Amended Summons.
The Court finds YMC guilty of the offence charged.
In this matter, I make the following orders:
YMC is guilty of the offence charged.
The matter will be listed for sentence on a date suitable to the parties.
“The company’s duty required it to manage, in accordance with section 17 of the WHS Act, the risk of workers suffering death or serious injury as a result of being entangled in, or holding an item that became entangled in, or crushed by moving parts of the Mobile Screen while cleaning the Mobile Screen (the Risk).”
“20. The defendant failed to exercise due diligence to ensure that the company complied with its duty under section 19(1) of the WHS Act because he failed to take one or more of the “reasonable steps” set out below to ensure the company complied with its duty:
(a) Prohibiting the operation of the Mobile Screen to screen material:
(i) during wet weather;
(ii) when the material was wet;
(b) Providing the company with a nominated competent person, who had acquired through training, qualification or experience the knowledge and skills to carry out the task of supervising mining operations at a mine, to perform the function of quarry manager of the mine;
(c) Requiring, instructing or directing the company to provide training, information and instruction to workers on:
(i) the “Standard Operating Procedure – Isolation” dated 27 October 2017;
(ii) the “Standard Operating Procedure - Mobile Screen” dated 3 February 2022;
(iii) the Mobile Screen’s Product User Manual Operation and Maintenance;
(iv) a safe system of work for clearing built-up of mud in the Mobile Screen that required the Mobile Screen to be isolated and locked out and the use of fit for purpose tools, such as a high-pressure hose and/or other tool such as a shovel;
(d) Verifying that the documented procedures listed in paragraph 20(d) above were used by the company by:
(i) requiring the mine’s on-site personnel to report to officers on safety matters and compliance with the mine’s safety management system;
(ii) conducting regular inspections of plant including the Mobile Screen, and/or causing others to conduct regular inspection of plant including the Mobile Screen and report the outcome to him;
(iii) conducting inspections of work practices including operation, cleaning and maintenance of the Mobile Screen or ensuring an appropriately qualified supervisor conducted inspections of work practices, including, cleaning of the Mobile Screen, and reporting the outcome to him;
(iv) reviewing the mine’s training records, or causing others to review the mine’s training records and report the outcome to him;
(v) reviewing the mine’s plant inspection records, or causing others to review the mine’s plant inspection records and report the outcome of such inspections to him;
(vi) undertaking audits to verify the implementation and compliance with the mine’s safety management system, or causing others to undertake audits to verify the implementation and compliance with the mine’s safety management system and report the outcome to him.”
Paragraph 21 of Annexure A to the Jhunjhunwala Summons pleaded that as a result of the failures of Mr Jhunjhunwala to take one or more of the reasonable steps identified in paragraph 20, he failed to comply with his duty under s 27(1) of the WHS Act.
Paragraph 22 of Annexure A to the Jhunjhunwala Summons pleaded that as a result of Mr Jhunjhunwala’s failure to comply with his duty, workers, including Mr Coupland and Mr Wells, were exposed to the pleaded risk.
27 Duty of officers
(1) If a person conducting a business or undertaking has a duty or obligation under this Act, an officer of the person conducting the business or undertaking must exercise due diligence to ensure that the person conducting the business or undertaking complies with that duty or obligation.
(2) Subject to subsection (3), the maximum penalty applicable under Division 5 of this Part for an offence relating to the duty of an officer under this section is the maximum penalty fixed for an officer of a person conducting a business or undertaking for that offence.
(3) Despite anything to the contrary in section 33, if the duty or obligation of a person conducting a business or undertaking was imposed under a provision other than a provision of Division 2 or 3 of this Part or this Division, the maximum penalty under section 33 for an offence by an officer under section 33 in relation to the duty or obligation is the maximum penalty fixed under the provision creating the duty or obligation for an individual who fails to comply with the duty or obligation.
(4) An officer of a person conducting a business or undertaking may be convicted or found guilty of an offence under this Act relating to a duty under this section whether or not the person conducting the business or undertaking has been convicted or found guilty of an offence under this Act relating to the duty or obligation.
(5) In this section, due diligence includes taking reasonable steps—
(a) to acquire and keep up-to-date knowledge of work health and safety matters, and
(b) to gain an understanding of the nature of the operations of the business or undertaking of the person conducting the business or undertaking and generally of the hazards and risks associated with those operations, and
(c) to ensure that the person conducting the business or undertaking has available for use, and uses, appropriate resources and processes to eliminate or minimise risks to health and safety from work carried out as part of the conduct of the business or undertaking, and
(d) to ensure that the person conducting the business or undertaking has appropriate processes for receiving and considering information regarding incidents, hazards and risks and responding in a timely way to that information, and
(e) to ensure that the person conducting the business or undertaking has, and implements, processes for complying with any duty or obligation of the person conducting the business or undertaking under this Act, and
Example—
For the purposes of paragraph (e), the duties or obligations under this Act of a person conducting a business or undertaking may include—
• reporting notifiable incidents,
• consulting with workers,
• ensuring compliance with notices issued under this Act,

• ensuring that health and safety representatives receive their entitlements to training.
(f) to verify the provision and use of the resources and processes referred to in paragraphs (c)–(e).
Section 4 of the WHS Act contains a definition of “officer”, which includes “an officer within the meaning of s 9 of the Corporations Act 2001 (Cth) of the Commonwealth other than a partner in a partnership”.
The definition of “officer of a corporation” in s 9 of the Corporations Act includes “a director or secretary of the corporation”. Mr Jhunjhunwala was the Managing Director of YMC at the relevant time.
The elements of a Category 2 offence involving the failure of an officer to exercise due diligence as required by s 27 of the WHS Act are:
Element A The defendant was an officer of YMC.
Element B YMC owed a health and safety duty to workers, including Mr Coupland and Mr Wells.
Element C The defendant failed to exercise due diligence to ensure that YMC complied with its duty.
Element D The defendant’s failure exposed workers, including Mr Coupland and Mr Wells to a risk of death or serious injury.
“Section 27 is a straightforward implementation of recommendation 40 of the First Report of the National Review, which was that a new Model Act should ‘place a positive duty on an officer to exercise due diligence to ensure the compliance by the entity of which they are an officer with the duties of care’ under the Act. The positive duty imposed by s 27 requires officers to be proactive and means that officers owe a continuous duty to ensure compliance with duties and obligations under the Act.”
“The officer’s duty is to exercise due diligence to ensure that the PCBU complies with the PCBU’s duties or obligations (subs 27(1)). This ordinary grammatical meaning is further extended by subsection 27(5) of the Act. The definition is framed in an ‘inclusive’, rather than ‘exclusive’, way. Due diligence now includes (etc) knowledge of work health and safety matters, understanding the hazards and risks associated with the business or undertaking’s operations, and resources and processes to eliminate or minimise the risks. Unlike s 26 of the OHS Act 2000 which required that the relevant company actually contravene the legislation, it appears an officer may be guilty under s 27 of the Act simply by failing to exercise due diligence, even if the company itself has not been charged or been found guilty of a breach. Due diligence also concerns information about incidents, hazards and risks, processes for complying with the PCBU’s duties and obligations, and arrangements to verify the provision and use of resources and processes.
The standard of care prescribed for officers in s 27 is ‘due diligence’. The Oxford English Dictionary defines the word ‘diligence’ as, simply: Constant and earnest effort to accomplish what is undertaken; persistent application and endeavour; industry, assiduity.
Subsection 27(5) requires an officer to be proactive in acquiring and keeping up-to-date knowledge of work health and safety matters and ensuring the PCBU has, and implements, processes for complying with any duty or obligation the PCBU has under the Act. It is a high standard to be reached. It does not place the officer directly in the position of the corporation, but requires the officer to be actively engaged in the governance of the corporation.”
“37 The scope of the duty imposed by section 27 of the Act has not been authoritatively determined. The following matters appear to be non-controversial.
38 First, the section 27 duty is radically different to its predecessor section 26 Occupational Health and Safety Act 2000, which deemed a director on proof of a contravention by the company. The first report of the Stewart-Crompton Panel (the First Report) described section 27 as requiring an officer to be proactive to ensure compliance by the company, making the officer liable for their own acts or omissions. The approach was intended to require proactive steps by the officer for compliance by the company, with the duties of care placed on the company.
39 In McKie v Al-Hassani [2015] ACTIC 1, Chief Industrial Magistrate cited with approval the following relevant passage from Barry Sherriff and Michael Tooma, (Understanding the Model Work Health and Safety Act) (Wolters Kluher):
“‘The approach taken by the model WHS Act, however, emphasises the corporate governance responsibilities of officers. The personal liability in that context reflects culpability of company officers in failing to meet the corporate governance responsibilities by preventing corporate misconduct. Consistent with this rationale, officers under the model laws will have a duty to ensure due diligence. Thus, their attributed liability is transformed into a positive duty to ensure compliance through sound corporate governance.’”
40 Second, ‘due diligence’ is defined to include taking reasonable steps to achieve the objectives set out in section 27(5)(a)-(f), but the definition of due diligence is not closed. ‘Due diligence’ in the context of the Corporations Act 2001 (Cth) has been defined as a minimum standard of behaviour involving a system which provides against contravention of relevant regulatory provisions and adequate supervision ensuring that the system is properly carried out: Universal Telecasters (Qld) Ltd v Guthrie (1978) 18 ALR 531.
41 In Inspector Kumar v Ritchie [2006] NSWIRComm 323 at [153] Haylen J considered that the due diligence defence provided for by section 26 Occupational Health and Safety Act 2000 required a systematic approach designed to achieve compliance with the regulatory scheme and to prevent contravention of it, that the system was appropriate and not a paper system designed to pay lip service to the Act and that the system was properly enforced to achieve compliance with the Act.
42 In WorkCover Authority v Daly Smith Corporation [2004] NSWIRComm 349 at [152] Staunton J described the due diligence defence as requiring that the person had put in place a system to identify and manage the risk to safety at the employer’s worksite. It involved ensuring that the workers had the skills to perform the work and ensuring that they complied with the safety standards established, by formal and informal review and auditing.
43 In Inspector Aldred v Herbert [2007] NSWIRComm 170 at [25] Backman J held that it was sufficient due diligence for directors to address safety matters at board meetings, to require managers to report on safety matters and to monitor safety as an issue.
44 In Inspector Hayes v Santos and Lorenzo [2009] NSWIRComm 163 at [188] Boland P was not satisfied that the due diligence defence was established because there was no review or auditing process to ensure that the supervisors and managers were acting in compliance with the written policies.
45 Third, the exercise of due diligence and what are reasonable steps will be determined to some extent by the officer’s place in the corporate structure and their ability to control the objectives outlined in section 27(5)(a)-(f).”
“56 The section 27 duty imposed on officers is not to take all reasonably practical measures to ensure compliance by the PCBU and an officer is not required to ensure the health and safety of workers.
57 An officer is required to adhere to a minimum standard of behaviour involving a system which ensures compliance by the PCBU with its duties and obligations under the Act and to provide adequate supervision to ensure that the system is properly carried out. The minimal standard of behaviour and the system is to take reasonable steps to include the objectives in section 27(5)(a)-(g).
58 Section 27 does not require that the officer undertake the reasonably practicable measures on behalf of the PCBU. A breach of section 27 by an officer is not dependent on a breach of another duty owed by the PCBU.”
“At p 5 of the paper Mr Hodgkinson SC says:
‘Much of the confusion as to the scope of the Officers’ duty of due diligence has been caused by regulators who pursue actions under s 27 as though it imposes on the Officer the same duty imposed by s 19 on a PCBU. It is clear from a consideration of s 19 and s 27 that the duties are different. In short form, an Officer is required under s 27 to understand the PCBU to the extent of being able to identify the risks and hazards associated with its business or undertaking and to ensure that the PCBU has the necessary systems and resources to meet its s 19 primary duty of care.’”
“39 Mr Hodgkinson SC expressed his conclusions on p 13 of the paper as follows:
‘I will leave you with four brief statements regarding the s 27 duty of due diligence.
First, beware of prosecutions which equate the PCBU’s duty of primary care under s 19, and Officers’ duty of due diligence under s 27. It is likely that the court will identify that the duties imposed on Officers are different to those imposed on PCBU’s or the duties themselves are different. If the duties are in fact the same then s 27 is little more than a deeming provision, by which I mean that the Officer would be deemed guilty of the PCBU’s breach.
Second, conceptualise s 27 instead as imposing a duty to ‘ensure to ensure’. By that, I mean the s 27 duty of due diligence is one which will require the Officer to take steps to equip the PCBU with the necessary systems and resources so that the PCBU itself can meet its relevant duties and obligations.
Third, Officers must take steps which enable them to understand the risks and hazards associated with the business or undertaking in which the PCBU is involved. They must be aware that the PCBU is taking appropriate steps to ensure that no one is exposed to a risk to their health and safety as a consequence of those risks and hazards.
Fourth, it seems that the s 27 duty of due diligence imposes on Officers the duty to take reasonable steps to, at the least: ensure those under them carry out their own duties properly, confirm the existence of and review WHS documents, become aware of prior incidents, supervise and train workers, and to ensure that plant is safe and personal protective equipment is provided and worn.’
40 I respectfully agree that the conclusions expressed by Mr Hodgkinson SC immediately above are an accurate statement of how to conceptualise the duty of an officer of a corporation under s 27 of the WHS Act.”
I respectfully agree both with Scotting DCJ and Mr Hodgkinson AM SC.
The learned authors of Work Health and Safety Regulation in Australia consider the scope of the duty under s 27(1) to be as follows (p 138-139):
“This is a proactive, positive duty. Officers are not attributed with liability for conduct of their PCBU. This is not a ‘piercing of the corporate veil’ to impose liability on officers. Rather, officers have a duty of due diligence which they must discharge much in the same way that a PCBU (which may, as we have seen in Chapter 2, be a corporation, unincorporated association, partnership or the Crown) is required to discharge its duty of care and that a worker is required to discharge their duty of care. This was the deliberate and express recommendation of the National Review panel, which, in recommendation 42, recommended creating ‘a positive duty on an officer to ensure a corporation complies with its duties under the model Act’. That duty would be ‘qualified by a requirement to exercise due diligence, as it applies to the responsibilities of officers (having regard to their position) within the organisation’. The officer would be ‘liable for his/her own conduct or omission’, not that of another person. The onus of proving a failure to meet the standard of due diligence would be on the prosecution. The National Review panel observed that:
The provision creates a positive duty which is seen to apply immediately, rather than accountability only applying after a contravention by the company. The duty would make clear that the officer must be proactive in taking steps to ensure compliance by the company …
By making the officer liable only for his or her own acts or omissions would provide a sense of control by the officer over their personal liability and a sense of fairness … [This approach] is more likely than the other options to ensure appropriate, proactive, steps are taken by an officer for compliance by the company with the duties of care placed on the company.
Section 27 severs the link between the duty of care of the company and the duty of the officer. An officer is not liable merely because their PCBU failed to comply with its legal obligations. Indeed, an officer of a PCBU can be convicted of breach of the duty of care to exercise due diligence whether or not the PCBU has been convicted or found guilty of an offence under the Work Health and Safety Acts (s 27(4)). Conversely, an officer is not absolved of liability merely because their PCBU complies with its obligations. The test of liability lies in the officer’s conduct. If an officer exercises due diligence, they cannot be liable, regardless of the conduct of the PCBU. If an officer fails to exercise due diligence, they are liable regardless of the conduct of the PCBU. Most importantly, the duty lies on each officer. An officer cannot discharge the duty by pointing to the due diligence exercised by another officer of the PCBU.”
“Due diligence is therefore defined under the Work Health and Safety Acts to consist of six components:
- Knowledge of work health and safety matters.
- Understanding of the nature of the operations of the business and the hazards and risks associated with those operations.
3. Resources and processes.
- Information regarding incidents, hazards and risks and responding in a timely way to that information.
- Legal compliance.
- Verification of the provision and use of these resources and processes.
Each officer must take ‘reasonable steps’ in relation to each of these elements.”
“[Due diligence] is not done by merely hoping others would or could do what they were told, but also ensuring they have the skills to execute the job they are required to do and then ensuring compliance with that in accordance with the safe standards established. Compliance requires a process of review and auditing, both formal and random, in order to ensure that the safety standards established are in fact being adhered to and under ongoing review.”
The requirement to exercise due diligence is a requirement to be involved in the governance of the PCBU. Section 27(5) of the WHS Act provides a list of concrete examples of what that looks like in practice, the breadth of which is likely to be all encompassing. In essence, the requirement to exercise due diligence has the following three limbs:
Understanding and keeping abreast of developments concerning work health and safety matters;
Understanding the business of the PCBU to the extent of being able to identify the risks and hazards associated with its business or undertaking; and
Ensuring that the PCBU has the necessary systems and resources to comply with its work health and safety duties under the WHS Act.
The outworking of that obligation will necessarily differ in accordance with the size of the company. The sole director of a PCBU who is also the sole employee of that PCBU is the arms and legs of that PCBU. Ensuring that such a PCBU has the necessary systems and resources in place to comply with its work health and safety duties under the WHS Act will require such an officer to personally marshal resources and implement appropriate systems. In that scenario, it will usually be sufficient to plead that the officer failed to have the PCBU take one or more reasonably practicable particularised steps to ensure safety and list the failures of the PCBU that the officer permitted or failed to prevent. It will not be necessary to particularise how the officer would require the PCBU to take a step that, on the case as pleaded, could only be taken by the action of that officer.
However, for officers of most PCBUs, it will be necessary to identify what they have done with more particularity than simply asserting a failure to ensure that the PCBU took particularised steps. Rather, the charge will need to plead the actual step or steps that the officer should have taken to meet their s 27(1) duty but did not. For a small PCBU that might, for example, be a failure to verify through personal inspection that the PCBU had effective risk identification and mitigation systems in place or a failure to issue written or verbal directions that the PCBU implement such systems. That context is vastly different to that of a PCBU which is a large corporation with hundreds or thousands of employees, including an executive management team, and a board of directors. In that scenario, the particular of breach of the officer’s duty to exercise due diligence is unlikely to be the failure to require the PCBU to take a particular step because of the unlikelihood that the officer was sufficiently involved in the particular operation or event giving rise to an exposure to a risk to health and safety. Rather, a valid particular is more likely to be a failure to take a step that would have reduced the likelihood that the PCBU would fail to comply with its WHS Act duty, such as making available a budget to allow for the engagement of external expertise that would result in more effective WHS training for staff or the implementation of safer work systems or requiring the production of regular reports about the control measures being implemented to address risks to health and safety identified in the PCBU’s business and acting upon the content of those reports in a timely manner.
Each matter will turn on its own facts as to where it sits on the spectrum and therefore what the substance of an officer’s duty to exercise due diligence entails. However, consistent with Kirk v Industrial Court of New South Wales (2010) 239 CLR 531 at [28] (Kirk), in each case the particular must clearly identify an act or omission which constitutes a contravention of s 27(1) of the WHS Act. It is unlikely to be sufficient to identify the failing of the officer by reference to the list of due diligence obligations in s 27(5) of the WHS Act and plead that the officer failed to meet one or more of them in a way that caused the PCBU to fail in the way particularised.
It is an agreed fact that YMC is a wholly owned subsidiary of Orind Australia Pty Ltd. There is no evidence before the Court about that company, beyond the fact that it has two wholly owned subsidiaries, being YMC and Causmag.
Exhibit ZZ109 is the ASIC Current and Historical Company Extract for YMC as at 8 June 2023. It reveals that at the date of the incident, YMC had three directors, only one of whom, Mr Jhunjhunwala, was a resident in Australia. He was the Managing Director of YMC. The remaining directors, who are also officers of YMC as defined by s 4 of the WHS Act, resided in India. One of those directors, Surendra Kumar Jhunjhunwala would appear to be a relative of Mr Jhunjhunwala. The secretary of YMC, Rajshree Jhunjhunwala resides with Mr Jhunjhunwala and so would appear to be a close relative of Mr Jhunjhunwala. Accordingly, YMC would appear in essence to be a small family company.
Exhibit PP84 is a list of company officers as at 19 September 2022 provided by Mr Pandey, in response to a s 155 Notice (Exhibit PP83). In addition to Mr Jhunjhunwala and the Company Secretary, that document lists the following people:
Rick Price – Supervisor
Bipin Pandey – Manager Finance and Admin
Rahul Goel – Management Accountant
Chaparala Vijaya Kumar – Assistant Accounts Manager.
The list also states that all of the officers except for Mr Jhunjhunwala and Mr Rick Price were employees of Causmag. So far as his own employment status is concerned, this is consistent with other representations made by Mr Pandey who signed correspondence “for Young Mining Company Pty Ltd” and operated using a Causmag e-mail address (Exhibit DD11, Exhibit OO21). Mr Pandey stated that all officers other than Mr Rick Price worked at the head office in Young.
Mr Rick Price’s evidence, which I accept, was that he was employed to operate the Mobile Screen (T92.13; T94.37-40). This is consistent with his induction form which described his position as “Operator” (Exhibit Q). It is also significant that, at the time when Mr Rick Price was employed at the mine, Mr Zeb Harris worked at the mine in the role of Quarry Operator or Quarry Manager (T94.122-23). Mr Rick Price expressly stated that he was not the Quarry Manager and that when he signed the induction form for Mr Coupland, he did so because the Quarry Manager was not available and told him to sign the form (T104.37-T105.2). Given that evidence, it is difficult to accept Mr Pandey’s evidence that Mr Rick Price was an officer of YMC as defined in s 4 of the WHS Act.
The evidence before the Court was that, at the time of the incident, YMC had few employees. Only Mr Rick Price, Mr Coupland and Mr Wells were working at the mine. The only other YMC employee at that time was Mr Jhunjhunwala. I have already found that there was no competent person operating as the Quarry Manager at the time of the incident. In fact, there was no site supervisor on site at all because Mr Rick Price did not consider himself to be the site supervisor and had expressly told Mr Jhunjhunwala that he was not interested in completing the necessary paperwork for the mine to operate. That circumstance was an important one in determining what was required of Mr Jhunjhunwala to comply with his duty to exercise due diligence to ensure that YMC complied with its WHS Act duty.
In final submissions, counsel for Mr Jhunjhunwala was critical of the form of the Further Amended Summons. Mr Jhunjhunwala’s primary submission was that the particulars of his alleged breach of the WHS Act pleaded by the prosecutor do not specify the steps that he should have taken to discharge his duty under s 27(1) of the WHS Act. Rather they allege that he should have done something to ensure that YMC complied with its duties. As such, it is submitted that the pleaded particulars fail to come to grips with the separate requirement of due diligence enacted by s 27 and should be struck out. In addition, counsel for Mr Jhunjhunwala submits that the pleaded particulars fail to meet the requirements of Kirk at [27]-[28], in that they plead a conclusion rather than an omission.
The pleaded measures which it is alleged Mr Jhunjhunwala should have taken to meet his duty to exercise due diligence are set out at [175] above. Measure 20(a) alleges a failure to prohibit workers from operating the Mobile Screen during wet weather; when the material was wet. This measure implies that Mr Jhunjhunwala should have personally told the workers on site that the Mobile Screen should not be used in such conditions. I am of the view that this is capable of being a reasonable step in the system adopted by Mr Jhunjhunwala to ensure that YMC complied with its WHS Act duties, particularly in the absence of a site supervisor. I am also of the view that this pleading meets the Kirk requirements.
Measure 20(b) alleges a failure by Mr Jhunjhunwala to provide the company with a nominated competent person with the appropriate knowledge and skills to carry out the task of supervising the mining operations to perform the function of Quarry Manager. This particular implies that Mr Jhunjhunwala should have personally identified someone to perform that role. It is not stated how he should have done so, for example by advertising the position and interviewing applicants, by sourcing such a person by word of mouth or by undertaking that role himself. In my view the pleading falls short of the Kirk requirements and should be struck out.
If I am wrong about that, I further note that I have set out at [168] above my reasons for finding that the failure of YMC to appoint a competent person as the Quarry Manager was not a significant or substantial cause of the exposure of workers, and in particular Mr Coupland and Mr Wells, to a risk of death or serious injury. For those same reasons I would find that the failure of Mr Jhunjhunwala to provide the company with a nominated competent person to function as the Quarry Manager was not a significant or substantial cause of the exposure of workers to the pleaded risk. Accordingly, to the extent that the prosecution of Mr Jhunjhunwala relies on this measure, it would fail in any event.
Measure 20(c) alleges a failure by Mr Jhunjhunwala to require, instruct, or direct YMC to provide training, information and instruction to workers on a series of specified procedures. Mr Jhunjhunwala submitted, and I accept that each of require, instruct and direct is pleaded in the alternative, and so appear intended to capture a series of different acts that could have been taken by Mr Jhunjhunwala, each of which was individually sufficient to discharge his duty. Further, in circumstances where there was no site manager at the mine after Mr Harris ceased employment, it is unclear how Mr Jhunjhunwala was to require, instruct, or direct YMC to provide the specified training and instruction to workers. At the date of the incident, the only people at the mine were the workers, none of whom had received any training in the stipulated procedures. Therefore, even assuming that the duty would have been satisfied by Mr Jhunjhunwala saying, “provide training information and instruction to workers on the Isolation SOP”, it is entirely unclear how that could have been achieved. Therefore, again, my view is that the pleading falls short of the Kirk requirements and should be struck out.
Again, if I am wrong about that, I have set out at [167] above my reasons for finding that the failure of YMC to provide the specified training was not a significant or substantial cause of the exposure of workers, and in particular Mr Coupland and Mr Wells, to a risk of death or serious injury. For those same reasons I find that the failure of Mr Jhunjhunwala to require, instruct or direct the company to provide training, information and instruction to workers on all four of the specified procedures was not a significant or substantial cause of the exposure of workers to such a risk. The procedures are not pleaded in the alternative. Accordingly, to the extent that the prosecution of Mr Jhunjhunwala relies on this measure, it would fail in any event.
Measure 20(d) requires Mr Jhunjhunwala to verify that specified procedures were used by YMC by requiring on site personnel to report to officers of YMC on safety matters, conducting inspections of plant and work practices, reviewing training and plant inspection records and undertaking audits of compliance with mine safety systems. The obvious issue with this particular is that it refers to the procedures listed “in paragraph 20(d) above”. As paragraph 20(d) is the instant paragraph, this must be a typographical error with the intended reference being to paragraph 20(c). The point was not taken by Mr Jhunjhunwala, and I read the reference as “paragraph 20(c) above”.
The pleaded activities fall squarely within the system to be implemented by Mr Jhunjhunwala to ensure compliance by YMC with its WHS Act duties. Further, the measure meets the Kir**k requirements as it pleads specific tasks which it is said that Mr Jhunjhunwala should have undertaken to verify that the stated procedures were used by YMC.
In the event that I found the pleaded measures valid, Mr Jhunjhunwala relied on the submissions made by YMC to the extent that they apply in this context to him. Accordingly, I turn to deal with measures 20(a) and (d).
I have found, for the reasons set out above, that the Isolation SOP and the First and Second Mobile Screen SOP were not implemented and enforced. It follows that Mr Jhunjhunwala could not have verified their use by YMC.
For the reasons set out at [121], I cannot find beyond reasonable doubt that workers had not read the User Manual or the SWMS. However, as noted above, Mr Rick Price and Mr Wells developed their own procedure for cleaning mud off the Mobile Screen. They did not use the procedure in either the User Manual or the SWMS. The procedure which they did use was not documented. It follows that Mr Jhunjhunwala could not have verified that YMC used either the User Manual or another documented safe system of work for clearing built up mud in the Mobile Screen. Accordingly, the prosecutor has established Element C of the offence beyond reasonable doubt in respect of this measure.
The prosecutor has been unable to prove beyond reasonable doubt the elements of the offence under s 27 and s 32 of the WHS Act.
The Court finds Aditya Jhunjhunwala not guilty of the offence charged.
In this matter, I make the following orders:
The prosecutor has been unable to prove beyond reasonable doubt the elements of the offence charged.
The matter will be listed on a date suitable to the parties for entry of final orders and determination of costs or argument on the proposed questions of law to be stated to the Full Bench.
