Statement of the case
10 On Saturday 6 May 2000 the appellant was engaged in his ordinary duties as a security guard, patrolling the "Glasshouse". He had been rostered to work a day shift. He commenced work shortly before 6:00 am.
11 At about 10:30 am he took a designated goods lift known as "Lift No 7" to Level 23 of the building. When he arrived he stepped out of the lift intending to turn right to turn on the lights to the floor. As he stepped out of the lift he tripped over an empty milk crate which was immediately in front of the lift door. He fell heavily onto his knee and injured himself. A photograph marked by the appellant at the trial shows that the milk crate was virtually on the "doorstep" of the floor. It was between the two walls which formed the recess into which the lift doors were set.
12 As I have noted the appellant sued three parties: Knight Frank (NSW) Limited, the managing agent of the building, Ebsworths, the firm of solicitors which occupied Level 23 and Allcorp Cleaning Services Pty Limited, the cleaning company contracted by the managing agent to clean the building. He sought to establish that at last one of them was responsible for the crate being left in the position where he tripped over it and that it was negligent to leave it there.
13 The evidence disclosed that Lift No 7 was used by the milkman, cleaners and security guards to carry out their respective duties.
14 Ebsworths engaged a catering manager, Mrs Toy, who worked from Level 23. She gave evidence that Ebsworths had a regular milk order which was delivered to Level 23 each morning in a crate. When she arrived at work at about 9:00 am each morning, the crate of milk was in the kitchen. She would empty the crate and put the crate in the utility room. She said that at the end of the day the crate was placed against the wall in the foyer on Level 23 to the left hand side of Lift No 7 for the milkman to collect the following morning. She said that occasionally she put the crate out before she left at 5:00 pm, but more often than not the cleaners would put the crate out beside the lift.
15 Mr Brown, who had a milk delivery contract with Ebsworths, gave evidence that it was his practice to make milk deliveries from Lift No 7. He said that he would enter the lift from Level 2 with his trolley. When the lift door opened at Level 23, he would hold the door open with his foot, place the full crate of milk on the floor beside the lift and remove the empty crate.
16 The cleaners used Lift No 7 to remover rubbish and other materials from the Glasshouse on a daily basis. The practice amongst the tenants and cleaners appears to have been that, at least on Level 23, these materials were left close to the side of Lift No 7. This was done for easy collection. The materials were collected and transported down to Level 2, where rubbish and other materials were stored before being removed from the building. The primary judge found that on occasions milk crates could be left near or directly in front of the doors of Lift No 7.
17 The cleaners started cleaning the tower each weekday evening at 5:00 pm. Mr Kamel, the third respondent's leading hand at the Glasshouse, gave evidence that the procedure was that the cleaners would work in a team. On each floor, a cleaner would empty the rubbish bins into large plastic bags and place them at Lift No 7 to await collection. Mr Kamel would start at the top floor and, using Lift No 7, would go to each floor in turn and collect the rubbish waiting at the lift door. Mr Kamel agreed that from time to time he had removed a milk crate full of rubbish from the lift foyer which had been left at the lifts, although he said it was not the cleaners' responsibility to remove empty milk crates. The cleaners finished their work at 9:00 pm and handed their keys in, presumably to the security guards.
18 Part of the security guards' job was to conduct patrols of the tower. They used Lift No. 7 for this purpose. It could be taken from the fifth floor where their offices were located to all other floors in the building.
19 One of the security guards' duties when on patrol was to keep an eye out for anything that could cause a security problem, for example, items blocking the fire doors. All of the guards who gave evidence, including the appellant, said that if they had seen a milk crate directly in front of the lift doors, it would have been moved either to the side of the lift or removed and taken to Level 2.
20 Darren Williams was the security guard who performed the evening shift prior to the shift on which the appellant was injured. He conducted a patrol of the tower commencing at about 11:55 pm and concluding at 1:08 am. He said that to conduct the patrol of Level 23 he would have left Lift No 7 and crossed the lift foyer to check the fire door was closed. In those circumstances, he said that if there had been a crate in front of the doors to Lift No 7 he would have noticed it and removed it.
21 Level 23 was closed to public access from 6:00 pm. After that hour access was only available using a security key. It was common ground, as I understand the evidence, that after 6:00 pm the night before the accident, the only people who could have had access to Level 23 using a security key were Ebsworths' partners or employees, the security guards or the cleaners. There was no suggestion of any forced entry by an intruder.
