49 Even if it might have been inferred that the only way KK could have been in a public toilet was when she participated in an outing, this overlooks the possibility she may have gone to a public toilet when she absconded about which there was also evidence. There was no evidence before his Honour regarding the sufficiency or otherwise of either the level of staffing provided for excursions by residents, or the level of supervision of a resident while in, or using, a public toilet, or when toileting generally. It was not open on the evidence for his Honour to find that there was insufficient supervision of residents when on an excursion, or that the inadequate supervision arose from a lack of planning as to the staffing level required for an excursion.
50 In any event, in relation to supervision, neither the charge nor the particulars of the charge alleged a failure by the appellant to provide adequate supervision of residents, but rather a failure to provide Ms Noonan with any sufficient supervision in relation to her dealing with clients.
51 Notwithstanding this error, we observe that the appellant pleaded guilty to an offence involving a failure to provide and maintain any sufficient procedure, policy or system to ensure the safety of Ms Noonan and a failure to provide Ms Noonan with any sufficient training, instruction and or supervision to ensure her safety against physical assault by clients who were known to be capable of violent behaviour towards others. In the context of what occurred, these were not insignificant failures.
52 The appellant's failures were causative of a risk of assault on an employee, Ms Noonan, by a client, KK. The circumstances giving rise to the risk were that KK was able to obtain a syringe without the appellant's knowledge. As the appellant accepted in submissions on appeal, its guilty plea flowed from an acceptance first there was not a sufficient system or procedure in place to ensure KK was not able to obtain the syringe, nor was there a sufficient system or procedure in place to prevent KK using the syringe to assault Ms Noonan. Moreover, the appellant had pleaded guilty to a failure to provide Ms Noonan with sufficient training, instruction and/or supervision in relation to her dealing with KK, who was known to become violent. As a consequence of the appellant's failures to ensure the safety of Ms Noonan, she was stabbed with the syringe. This injury does not, of itself, dictate the seriousness of the offence or the amount of penalty. However, the occurrence of death or serious injury may well manifest the degree of seriousness of the risk to health and safety to which persons may have been subjected: Hannah v Wonar Pty Ltd (1992) 34 AILR 333; Tyler v Sydney Electricity (1993) 47 IR 1 at 5; Independent Cargo and Wool Services Pty Ltd v Mingare (unreported, New South Wales Industrial Court, CT92/1041, 10 March 1994 at 4); Watson v Southern Asphalters Pty Ltd (1996) 83 IR 446 at 456; Lawrenson Diecasting Pty Ltd v WorkCover Authority of New South Wales (Inspector Ch'ng) (1999) 90 IR 464; Morrison v Powercoal Pty Ltd (2003) 130 IR 364 at [31]-[33]. In the present case, the risk of physical assault included the risk of being stabbed. Ms Noonan's stabbing injury manifested a serious risk.
53 KK had a history of physical aggression towards staff and other clients. She had an obsession with knives, scissors and other sharp objects. It was reasonably foreseeable that KK might obtain a sharp instrument (for instance, whilst on an outing or on the occasions she absconded) and thereby a risk might arise in the form of a physical assault on staff with that sharp instrument. That such a risk was foreseeable necessarily required the appellant to take steps to prevent it, or take every reasonably practicable step to ensure that it did not arise. The appellant had failed to take these steps, which were straightforward and were introduced after the assault. They included:
(1) KK remaining in a supervised environment at all times;
(2) In the event KK absconded, on her return she was to be directed to her bedroom by a staff member without touching her. If necessary, a second staff member was to assist;
(3) KK was to be directed to disrobe and shower, at which time staff would search her clothing for sharp objects.
54 This was not a case, however, where the employer ignored the known risk of clients acting in a violent manner or failed to take any steps available to it that would have prevented the incident occurring. Ms Thompson, in her submissions, described the systems of work and procedures in place at the time of the offence for managing clients and their challenging behaviours and these were summarised earlier. Ms Noonan was familiar with these systems and had read KK's Lifeplan and the re-active strategy document to assist Mercy Centre staff in dealing with KK when she exhibited challenging behaviour. The documents identified KK's obsession with sharp objects, her capacity to become physically aggressive and that she had absconded. The material also explained how to deal with KK, if she threatened with a weapon.
55 Whilst his Honour acknowledged that the appellant did not lack procedures in relation to safety and that "the defendant had endeavoured to put in place appropriate systems of induction of training and education in relation to Occupational Health and Safety", it was not apparent that his Honour gave sufficient weight to the systems and procedures in place at the appellant's place of work, in his overall assessment of the objective seriousness of the offence. In order to make an objective assessment of the seriousness of an offence it is necessary to have regard to those factors adverse to a defendant's position and those that are favourable. In the present case, whilst the appellant's failures constituted weaknesses in its overall system and procedures, which must be regarded as serious, given the potential consequences for the safety of staff, Sister Weekes' affidavit and the accompanying bundle demonstrated that significant attention had been paid by the appellant to putting in place systems and procedures that were designed not only for the welfare of the client, but also the safety, health and welfare of staff.
56 We note that the Clinical Programming Team has a significant input into the design, implementation and monitoring of these systems. This team comprises Sister Weekes - a clinical psychologist who holds a PhD in clinical psychology, a behaviour management specialist, residential house coordinators and other staff who specialise in disabilities. The systems and procedures in place indicated a proactive approach to occupational health and safety by the appellant.
57 In our opinion, his Honour had not properly weighed in the balance of relevant considerations in determining the objective seriousness of the offence, the evidence of Sister Weekes regarding the systems and procedures in place to protect staff from clients with violent tendencies. Accordingly, we consider his Honour erred.
Consideration - the 2003 offence
58 In relation to the 2003 incident, Hart CIM found:
(1) Ms Noonan had received "very little formal training in self defence including martial arts training which may have enabled her to defend herself against the physically stronger DS".
(2) There was no evidence to demonstrate that the risks associated with violent residents overpowering one of the staff had been contemplated and planned for by the appellant with appropriate staffing levels or backup procedures.
(3) There were two other persons in the residence who were known to have violent tendencies. A question arose as to whether Mr Thomas (Ms Noonan's co-worker at the time of the incident) would have been able to physically control the other two inmates who were prone to violence.
(4) The appellant's failure was due in part to staffing arrangements.
(5) Mr Thomas was delayed in rendering assistance to Ms Noonan because he had left the house to attend to an errand.
59 As to the first finding, Ms Noonan had:
(a) Obtained a certificate in Professional Assault Response Training after a three-day workshop in January 1997.
(b) Had represented to the appellant when applying for the House Manager position that she had experience in dealing with "challenging behaviour/assaultive clients" and presented a reference to the effect that over a 12 months period she had coped extremely well during trying and often physically dangerous situations due to challenging behaviours displayed by clients.
(c) On or about 1 October 2003, Ms Noonan attended a martial arts course provided by the appellant with Zen Do Kai Karate Albury/Wodonga which was to assist her to manage clients with challenging behaviours following the 4 December 2002 incident. In or about October or November 2002, the appellant had also made martial arts training available to staff prior to the 4 December 2002 incident with the same martial arts company.
60 As to his Honour's view that Ms Noonan had received very little self-defence training and more of it may have enabled her to defend herself against DS, we consider that there was a sufficient basis for his Honour to reach that conclusion.
61 However, given the paucity of evidence about improvements in training that may have been appropriate it is a factor that should not feature significantly in assessing the objective serious of the offence.
62 As to the second finding, that there was "no evidence" to indicate that the risks associated with violent residents overpowering one of the staff had been contemplated and planned for by the appellant with appropriate staffing levels or backup procedures, it is apparent that his Honour was mistaken. A significant amount of the appellant's systems and procedures were directed to minimising the risk of staff being subject to assault by a client and this was evident from Sister Weekes' evidence. In particular, it was known that DS had a history of challenging behaviour which could escalate into violence; the Clinical Programming Team had designed and monitored the implementation of a reactive strategy for DS; five to six hours of staff training in relation to DS and her behaviour was provided to staff, including Ms Noonan, on 16 December 2002; and, the progress of clients and how to respond to their challenging behaviours was discussed and monitored by the appellant during various staff meetings.
63 There was an extensive "Lifestyle and Intervention Plan to Assist [DS]". This included a section on "How to assist [DS] in the event of a challenging incident". It provided advice on the warning signs to look for in DS's behaviour that might lead to violence and stated, "Don't put yourself or others where it will be difficult to leave if required". There was also the following advice:
Under no circumstances are staff members to put themselves in situations where physical assault is likely.
64 Ms Noonan had read DS's file, which included the Lifestyle and Intervention Plan and reactive strategies to be followed when DS exhibited challenging behaviour.
65 In so far as staff levels and back up are concerned, the ratio of staff to clients was 2:3. At the time of the incident there were three clients in residence and two staff workers, Ms Noonan and Mr Thomas. Contrary to his Honour's finding, the evidence was that Mr Thomas was present in the group home when the attacked occurred, the residents and staff having just returned from purchasing groceries.
