Liability: the primary judge's reasons
5 The primary judge delivered a comprehensive judgment from which the following facts can be drawn.
6 The respondent was employed by the appellant as a dining room attendant at an Other Ranks' Army Mess at the Holsworthy Army Base. She was injured on 5 August 1999 when she slipped on margarine lying on the floor of the dining room. Her claim that the appellant had been negligent was fundamentally based on the proposition that it had failed to devise and maintain a safe system of work. The primary judge summarised the appellant's approach to the evidence at the outset of his judgment as follows:
"… no substantial challenge [was] mounted in cross-examination to the accounts given by the plaintiff or Mrs Cotter as to the nature of the premises, the occurrence of spillages and the pace at which each of the plaintiff and Mrs Cotter were required to work in order to carry out their duties, with a concomitant difficulty, amounting almost to an inability on the part of either of them, to attend seriously to the question of spillages during meal times until the thorough cleaning which took place after each meal time."
7 The primary judge made his findings against that background. The respondent's usual hours of work were from 10.30 am to 7.00 pm. When she arrived at work at about 10.30 am she assisted a Mrs Cotter who did the breakfast shift and worked until about 1.30 pm. By the time she arrived at work Mrs Cotter had cleaned the floor after breakfast. The respondent helped Mrs Cotter with the dishes, putting items in the fridge, putting milk away and helped her generally to clean up after breakfast.
8 The food was prepared in the kitchen of the premises. When served, it was laid out in bain-maries or similar containers provided for the four or five choices of dishes together with vegetables available for the diners. In addition there were refrigerators located in the dining room which were accessible to the diners. They contained various forms of sauce, yoghurt and milk, honey, Vegemite and lemon as well as margarine which was kept in tubs in the refrigerators. Desserts were also kept in the refrigerators.
9 The primary judge found that the diners took two approaches to the use of the margarine. One was that the diners removed the tubs from the refrigerator and took it to their table, or commonly, used a knife to remove margarine from the tub in the refrigerator and either spread it on bread (presumably while standing near the refrigerator) or put in on a bread and butter plate to be conveyed to the diner's table.
10 Luncheon was provided from noon until 1.30 pm. At the outset of lunch, the diners were required to approach the respondent who sat at a position described as "the point" and sign themselves into a book under her supervision. If they chose to pay for their meals at that time rather than have the cost deducted from their pay, they paid the respondent who, if required, would write them a receipt. There were in the order of 200 tables in the dining room. The respondent's estimate was that on an average day 150 to 200 diners could be expected to attend lunch. She estimated that there were approximately 150 there on the day of her accident. Mrs Cotter, however, thought there were more diners in the dining room on the day of the accident because there were people attending courses who had come from all over Australia.
11 Although, as I have noted, the luncheon period was from noon until 1.30 pm, in fact the last diner had to arrive by 1.15 pm because the dining room was expected to be cleared by 1.30 pm. As the diners arrived throughout that period and not all at once, the primary judge noted that it was necessary for the respondent to spend a fair bit of time sitting at "the point". She normally sat there until 12.30 pm at least, however her duties required her to be available to supervise the signing in process and to take payments from diners from noon until 1.15 pm.
12 From about 12.30 pm, however, she was usually in a position to assist Mrs Cotter with the other major duty to which they were required to attend during lunch, loading the dishwasher with plates and dishes returned to the dishwasher vicinity by diners.
13 The primary judge made the following finding concerning the habits of the diners:
"The evidence is clear that the process of dining in the other ranks' mess at Holsworthy was not particularly edifying. The plaintiff, speaking from years of experience at the premises, described the diners as 'like pigs'. Clearly, the operation of the dining room generated substantial occasions of spillage. That included spillage at the point of loading of plates with large spoons at the bain-maries. No doubt, there were opportunities for spillage as the plates were carried by the individual diners to their respective tables. The evidence also discloses that there was spillage from other sources as well, including spillages from the margarine. " (emphasis added)
14 He also described the circumstances in which the respondent and Mrs Cotter worked in the following terms:
"The plaintiff and [Ms] Cotter described their work, (that is in relation to ensuring that the dishwashers were fed and that the signing-in or payment was monitored) as entailing that they worked at a very fast pace such that there was no time available, in the ordinary course of events, for either of them to specifically patrol the dining room area in order to detect spillages. What actually happened, it seems to me, is what was described by [Ms] Cotter; that is, if either of them saw a spillage, then the 'slippery when wet' sign was grabbed and put in position until there was time to clean up the spillage, which was whenever things quietened down."
15 The respondent was responsible for cleaning the mess, including the floor, at the end of her shift every day after lunch. The respondent was aware food was regularly spilt in the mess but it was not something of which she was conscious at times when she was busy. She was not particularly thinking of it on the day of the accident.
16 On the day of her accident the respondent was taking cutlery from the kitchen to put into containers in the dining room at about 12.30 pm. She was carrying some cutlery in a basket. She walked out of the kitchen, along a passage and turned right into the dining room. The floor tiles were a creamy yellow colour. She slipped and fell on her back. When she looked down after the fall she saw that she had margarine on the culottes she was wearing. She also saw margarine on the floor. One of the army men came over to help her as, too, did a Ms Goodman, the secretary. Mrs Cotter also went to the respondent's assistance and helped getting her up from the ground. As she did so she knelt on the ground. She noticed afterwards that she had margarine on her hand.
17 The primary judge concluded that there was no doubt that the respondent had sustained her back injury when she slipped on margarine which had been spilt on the floor. He also was satisfied that the spillage of margarine and indeed of other substances such as the items being taken from the bain-marie, either being put on the plates or being taken to tables, the returning of plates from the tables to the dishwashing area, removal of sauces, desserts and such from the fridge and spilling vegetables and drinks was a common, everyday occurrence in the dining room.
18 The primary judge concluded that the respondent had demonstrated that the spillages represented a foreseeable risk of significant injury in circumstances where the appellant knew or ought to have known:
