It follows from what I have so far said that I am unable to accept the view expressed by the Chief Justice of South Australia. I turn then to consider whether a duty fell upon the grandfather because of the particular circumstances. In my opinion the grandfather owed no legal duty to the child to prevent her leaving the house at the time she apparently did so, even though the grandparents had assumed the place of her parents for the time being. Of course, they or one of them may have owed a duty to strangers likely to be caused injury by the wandering child. Carmarthenshire County Council v. Lewis [2] . But if so in particular circumstances, the child would not in my opinion necessarily have a cause of action against them or either of them. Did a situation arise in which an obligation to take care to protect the child against danger was imposed on the appellant? It is important to examine the developing events from the time the child cried out whilst near the rear of her uncle's house; the grandfather in my opinion then had no relevant legal duty towards her. However had he called her to come to him, he would have come under a duty to take reasonable care for her safety in relation to any danger to her which the crossing of the road would involve. That duty would spring in my opinion out of the fact that he beckoned her to him: or did something which he ought to have known would bring her to him. A stranger who did so could in my opinion in the same circumstances come under the same duty, if the child was likely to respond positively to his call. In the case of the applicant, this qualification is not necessary, in my opinion, because he was her grandfather. Whether or not there was then any relevant danger does not appear. There is no information as to the then state of traffic, if any, using the road in that vicinity. But, in any case, it is not clear on the evidence, and I doubt if there is really any evidence that the appellant did call the child to him. I think the predominant conclusion from the evidence is that the appellant's response to the child's cry was no more than a reassurance to her that she was not alone. The neighbour's description of the response as "natural in the circumstances" and the fact the appellant continued conversation with the neighbour - there being no suggestion of wantonness in the appellant's conduct - tend in that direction. There was therefore in my opinion no legal obligation imposed on the appellant by the situation which existed at the time of the child's cry or of the appellant's response: nor was there any relevant change in the situation until the child was seen by the appellant on the other side of the road opposite to where he then was. Accepting the trial judge's finding and the known presence of traffic then on the roadway, the appellant ought at that time to have realized the possibility of danger to the child should she attempt to cross the road. On his own statement he then contemplated crossing the road to her, no doubt as a means of protecting her. As the judge found, he had the opportunity to cross the road and to stop the child making any attempt to cross it. But did these facts impose a legal obligation upon him to go to her aid, so that upon his failure to do so with consequential damage to her, the child could have successfully sued him in tort? I think not. Whatever moral duty he may have had, and however imperative in good conscience, there was in my opinion no legal duty towards the child on which to base an action of negligence.
