1 MEAGHER JA: On 21 March 1993 a family held a christening party at the defendant's (ie the appellant's) premises. The matriarch of the family was one Giuiseppina Crisafi, and the child being christened was her great-grand-daughter. There were preset a variety of children and grandchildren. The party started at about 12.30pm and finished about 4.30pm. On the way out, the family (who left as a group) used an escalator to go from the floor on which the party was held to the floor immediately beneath it. First on the escalator seemed to be Mrs Crisafi, who had difficulty in getting both feet onto it. This led to other members of the group trying to help her. She fell, and other fell one by one over their predecessors. Five of the group suffered injuries, and sued in respect of them. They sued the appellant in the District Court. The matters were heard (in a consolidated action) before Quickenden ADCJ, and the plaintiffs (the present respondents) all succeeded. The present appeal is limited to the question of liability.
2 Since the plaintiffs sue in negligence they must be able to point to breach of a duty of care. They pleaded five different duties of care which they alleged were breached. They were as follows:
"*failure to ensure that the escalator was angled at a safe angle for the descent of pedestrians
*failure to ensure that the escalator proceeded at a speed that made it safe for a pedestrian to walk on
*failure to warn the Plaintiffs that the escalator was not safe to walk on
*failure to have and maintain a proper system for inspection and/or maintenance of the escalator
*failure to ensure that the mechanism to stop the escalator was accessible and not locked."
3 His Honour found that the second duty had been breached; ie that the appellant had failed to ensure that the escalator was not proceeding too quickly.
4 In this regard his Honour based himself fairly and squarely on the evidence of various of the plaintiffs that the escalator was operating too quickly, and in particular was operating more quickly than such machines usually do. Before his Honour the appellant argued strongly that such evidence had to be disregarded, as only a scientist could pronounce on the question of whether the escalator was travelling too fast. Indeed, it seems to have been almost its only submission. The submission was revived before us, but in a more muted form. It had, of course, to fail, as it is well established that a lay witness is entitled to draw on his experience to give an estimate of speed: see Cross on Evidence (6th edition) para 29090.
5 His Honour's finding in this regard is bolstered by the failure of the appellant's Maintenance Manager (who held that position both at the time of the accident and at the time of trial) to give evidence, thus suggesting that he was incapable of saying anything useful to rebut the finding of speed; by the fact that none of the witnesses who gave evidence of speed were cross-examined on that subject; and by the fact (found by his Honour) that the appellant "did fail to have a proper system for inspection and/or maintenance" of the escalator. Nor is the finding weakened by the further fact found by his Honour that there were other complaints that the escalator was going too quickly.
6 The obstacle to escaping his Honour's finding is the report of an expert, Mr Burfitt, who examined the escalator in detail, although two or three years later. At that time, Mr Burfitt concluded that the speed was within the limits set out in Australian Standard AS 1735.5 1986 escalators. But, bearing in mind the time which elapsed between the accident and Mr Burfitt's inspection, particularly as the Court was left in total ignorance as to what happened on the occasional inspection which might have taken place in this interval, I do not think any safe reliance can be placed on Mr Burfitt's conclusion.
7 I would recommend that the appeal be dismissed with costs.
8 POWELL JA: I have read in draft the Judgments which have been prepared by Meagher JA and Stein JA.
9 Had it not been for the way in which the trial was conducted on behalf of the Appellant, and the state in which the evidence was left at the end of the trial, I would have been disposed to think that the appeals should be upheld. I say this, first, since I am by no means satisfied that the range of cases in which non-expert opinion evidence, even if not objected to, is admissible is as extensive as their Honours suggest; and, second, since it seems to me that to say of an escalator no more than that "it went fast" (Black AB 44) or that "it was going quite fast" (Black AB 62) provides no foundation for a finding that there had been a negligent failure to ensure that the escalator proceeded at a pace which made it unsafe for a pedestrian to travel on.
10 The general rule is that a witness who is not an expert must only speak to facts within his, or her, own knowledge, and he, or she, will not be permitted - except under the circumstances referred to below, to express his or her own opinion (see, for example, Taylor on Evidence 11 Ed (1920) Vol 2 para 1414 p. 966; Phipson on Evidence 14 Ed (1990) paras. 32-53 p. 843).
11 Although the principle upon which what might be called non-expert opinion evidence, or evidence of belief, is admitted has been variously stated, it is probable that, ultimately, the basis for the admission of such evidence is one of necessity.
12 In Fryer v. Gathercole (1849) 13 Jur (Pt 1) 542, to which reference is made in Cross on Evidence 6 Aust Edn (2000) para. 29090 p. 828, in order to prove publication of a libellous pamphlet a witness said that she received from the defendant a copy of a pamphlet, of which she read some portions, and lent it to several persons in succession, who returned it to her, and although there was no mark upon it by which she could identify it she believed the copy which was produced was the same, but could not swear that it was. A rule for a new trial having been obtained on the ground that the pamphlet had not been sufficiently identified, Pollock C.B. said:
"This when examined is merely a question of degree or weight, there is some evidence for the jury; and as has been truly argued there are many cases of identification when the law would be rendered ridiculous if positive certainty were required from witnesses. If there were some legal evidence to go to the jury in this case there can be no doubt which way they would find, for the moral evidence is such that they would be justified in finding as they have done. The evidence in this case was therefore properly received, and objection to it goes merely to its value, and this rule must be discharged."
