“One may find that as a matter of history several people have been at fault and that if any one of them had acted properly the accident would not have happened, but that does not mean that the accident must be regarded as having been caused by the faults of all of them. One must discriminate between those faults which must be discarded as being too remote and those which must not. Sometimes it is proper to discard all but one and to regard that one as the sole cause, but in other cases it is proper to regard two or more as having jointly caused the accident. I doubt whether any test can be applied generally.”
“It would not ordinarily be reasonable to expect an occupier of premises having engaged a contractor whom he has reasonable grounds for regarding as competent, to supervise the contractor’s activities in order to ensure that he was discharging his duty to his employees to observe a safe system of work.
