MR BURTON'S LIABILITY IN NEGLIGENCE
21Mr Burton's concession that he owed a duty of care to Mr Brooks was in my view well-founded. As Mr Burton was the occupier of the premises upon which the accident occurred and Mr Brooks was a lawful entrant, Mr Burton owed Mr Brooks a duty to take reasonable care to avoid a foreseeable risk of injury ( Australian Safeway Stores Pty Ltd v Zaluzna [1987] HCA 7; (1987) 162 CLR 479 at 488). However, as in Thompson v Woolworths (Qld) Pty Ltd [2005] HCA 19; (2005) 221 CLR 234, Mr Burton's status as the occupier of the property was only one aspect of his relationship with Mr Brooks (see [24]). Mr Brooks was on the property for the purpose of assisting Mr Burton to undertake an activity that was for Mr Burton's benefit and, as the primary judge held, "the job was done ... the way the defendant [Mr Burton] wanted to do it. The plaintiff was simply helping" (Judgment p 7 quoted in [20] above). As the organiser of an activity involving a risk of injury to those engaged in it Mr Burton was "under a duty to use reasonable care in organising the activity to avoid or minimise that risk" ( Leighton Contractors Pty Ltd v Fox [2009] HCA 35; (2009) 240 CLR 1 at [20]; see also Thompson v Woolworths at [26] - [27]). The fact that Mr Brooks was not paid for his assistance did not lessen the duty that Mr Burton owed to him.
22Mr Burton's organisation of the activity indicated that he had a measure of control over what occurred. The control that he derived from this organisation supplemented that which arose out of his ownership and occupation of the property. Control is important "in identifying the evidence and nature of a duty of care" ( Thompson v Woolworths at [24]) both in occupier's liability cases (ibid) and in other contexts ( Agar v Hyde [2000] HCA 41; (2000) 201 CLR 552 at [16], [21], [81]; Graham Barclay Oysters Pty Ltd v Ryan [2002] HCA 54; (2002) 211 CLR 540 at [149] - [150]).
23For the purposes of resolving Mr Brooks' claim it is helpful to define Mr Burton's duty in more specific terms than those of these general formulations. Mr Burton submitted that the primary judge's purported formulation of Mr Burton's duty was, to use the expression that Gummow J used in Vairy v Wyong Shire Council [2005] HCA 62; (2005) 223 CLR 422, "devoid of meaningful content" (at [73]). This submission must be accepted as the purported formulation did not in fact identify the content of the duty.
24As in many cases, formulation of the duty that was owed here is not easy. A path has to be trodden between a formulation that is too general to be of assistance and one which is too specific and is influenced by hindsight (ibid at [70] - [73]; Roads and Traffic Authority (NSW) v Dederer [2007] HCA 42; [2007] 234 CLR 330 at [43] - [58]). Bearing in mind that Mr Brooks, in assisting Mr Burton, was working in close proximity to, and with his back to, a dangerous hazard, the duty that Mr Burton owed to Mr Brooks is in my view appropriately described as one to take reasonable care to avoid Mr Brooks falling back into the empty swimming pool.
25In considering whether Mr Burton breached this duty, it is necessary to focus upon the particular circumstances that led to Mr Brooks' accident, that is, those which occurred in relation to the particular mulberry tree branch that Mr Brooks was holding when he fell.
26Prior to the accident the parties had been engaged in the lopping process for half an hour or more without incident. Mr Brooks had been removing severed branches until Mr Burton came to the branch that was almost out of his reach and needed Mr Brooks to hold it so that Mr Burton might use the tip of his chainsaw to cut it. Particularly as the branches were long and to some extent "springy", it was in my view clearly foreseeable, in fact virtually inevitable, that Mr Brooks would have to hold the branch firmly and apply some tension to it in order to facilitate Mr Burton's use of the chainsaw on it.
27This was clearly what Mr Burton intended would happen when he asked Mr Brooks to hold the branch. This created a situation in which there was a significant risk that the tension Mr Brooks applied to the branch would suddenly be released as a result of the branch being severed or as a result of the branch being partially cut and then snapping. In turn this involved a risk of Mr Brooks (who was a large man, of some 130 kilograms in weight) losing his balance in the restricted area available for him to stand and of him falling backwards into the empty pool. A fall into an empty swimming pool would inevitably cause injuries, as did Mr Brooks' fall.
28In these circumstances I consider that it was negligent for Mr Burton to ask Mr Brooks to hold the branch to enable it to be cut without satisfying himself that, for one reason or another, an accident of the type that did occur would not occur. As the primary judge said in relation to the lopping generally, it was open to Mr Burton "not to do this work in this way in this place" (Judgment p 6). Particularly was this so in relation to the branch that Mr Brooks was holding when he fell. If the result was that that branch was not cut on that day, so be it. There was no imperative to cut it without adequate precautions being taken. The lopping of the trees was, as Mr Burton described it, only "an afterthought" (Transcript p 71).
29The magnitude of the risk of serious harm resulting to Mr Brooks was such that Mr Burton was not justified in proceeding with the activity in question without taking precautions to eliminate or substantially reduce that risk. Further, as I have said, the activity was one that it was open to Mr Burton to refrain from undertaking. In these circumstances it was not in my view incumbent upon Mr Brooks to identify the precautions that, if taken, would have enabled Mr Burton to proceed.
30The following observations that I made (with the concurrence of McColl JA and Sackville AJA) in relation to the situation in Agresta v Agresta [2010] NSWCA 330 at [21] are relevant by way of analogy to that in the present case:
"Unavailability of a replacement machine, or alternatively lack of proof by Mrs Agresta of the availability of an alternative machine, does not mean that the appellants were not negligent in allowing, or requesting, Mrs Agresta to use the existing machine. The alternative of not letting her use (or requesting her to use) the existing machine was readily available. Knowing of Mrs Agresta's lack of experience and being aware of the real prospect of Mrs Agresta being distracted in her operation of the machine, a reasonable person in the position of the appellants would not in my view have let her, or requested her to, take control of the machine on that day. The fact that there might have been another alternative available to the appellants, namely, to purchase an alternative machine which had appropriate safety features, is in these circumstances beside the point .".
31It is unnecessary in these circumstances to consider what precautions Mr Burton might have taken to reduce the risk sufficiently to enable the activity to proceed and whether the primary judge was entitled to have regard to what Mr Burn, an expert called by Mr Brooks, said about such precautions. The precautions to which the primary judge referred included placing boards across the end of the pool, putting a cover on it, placing a protective barrier near it and taking steps to do the work "in another way" (Judgment p 6).
32Mr Burton submitted that the primary judge's finding of negligence based upon his Honour's conclusion that it was open to Mr Burton "not to do this work in this way in this place" (Judgment p 6) fell outside the case pleaded. Mr Burton contended in this respect that Mr Brooks' counsel had indicated to the primary judge in opening the case that with limited exceptions the particulars of negligence contained in the Statement of Claim, which were in my view expressed broadly enough to encompass his Honour's findings as to negligence, would not be pressed.
33I do not agree that this occurred. The transcript reveals that in the course of the opening there was a lively exchange between counsel and the bench. It concluded with the primary judge saying "[s]o your case is really [put in] two ways", which his Honour identified. Counsel started to respond by adding reference to another matter but was cut off by his Honour saying "[s]afe place for carrying out work and those other matters you set out there" (Transcript p 4). His Honour was in my view clearly referring to the particulars of negligence, to which reference had already been made in the interchange, as set out in the Statement of Claim and was indicating an understanding that Mr Brooks relied upon all of those particulars.
34In any event, the primary judge's description of the second way in which Mr Brooks' argued his case (see [16] above) is a sufficient indication (in the absence of any transcript of Mr Brooks' closing address being available) that Mr Brooks maintained a broadly based case throughout the hearing. The fact that his Honour founded his decision, in the alternative, on the proposition that "the work could easily have been done in another way" itself suggests this.
35Before leaving the question of Mr Burton's liability, I refer to two additional matters that Mr Burton relied upon.
36First Mr Burton submitted that the departure that occurred in relation to the branch in question from the method that the parties had adopted for the previous half hour or so in lopping the trees was purely a matter of choice on the part of Mr Brooks. I do not agree. Mr Burton's evidence was that he asked Mr Brooks to hold this particular branch for him and, more generally, it is clear from the evidence and his Honour's judgment that Mr Burton was the person who determined what occurred in the foliage clearance. This was hardly surprising as Mr Burton was the owner and occupier of the property, the work was for his benefit and he had a ladder and chainsaw with which he undertook the primary role in the clearance.
37Secondly Mr Burton complained that the primary judge did not have sufficient regard to the provisions of the Civil Liability Act 2002. His Honour did however set out various provisions of the Act (see [16] above) and in my view did not fail, in a respect that is material to resolution of this appeal, to address any of the matters that the Act requires to be addressed. As I pointed out in Laresu Pty Ltd v Clark [2010] NSWCA 180; Aust Torts Reports [82-068], a failure by a primary judge to refer to relevant provisions of the Civil Liability Act does not vitiate the judge's decision if in material respects the judge has addressed the matters that the Act requires to be addressed ([41] - [42]).
