判决理由
Where a non-tortious supervening event (such as a naturally occurring illness) overtakes the original injury and would have produced the same disability regardless, the first tortfeasor's liability is limited to the period before the supervening event.
事实
Jobling slipped at work due to his employer's negligence in 1973, injuring his back. In 1976, before the trial, he developed an unrelated spinal condition (myelopathy) that rendered him totally unfit for work regardless of the original injury.
判决摘要
The House of Lords held that the employer's liability was limited to the period 1973-1976. The myelopathy was a fact of life — a vicissitude — that should be taken into account. It distinguished Baker v Willoughby on the basis that a tortious act should be treated differently from a natural event.
关键引述
"The question is essentially a practical one, and in my opinion a practical answer should be given to it."
— Lord Bridge
