On 12 October 2005, a fire destroyed or damaged a considerable number of mango trees on the appellant company's property. The fire allegedly originated from grass-cutting activities by employees of the Department of Roads and Transport on the road reserve of the D533 adjacent to the appellant's farm. A passerby noticed the fire and alerted Peter Spear, who contacted his brother John Spear (the appellant's managing director). The appellant dispatched a tractor with a 2,000 litre high pressure sprayer to fight the fire. When John Spear arrived, the fire had been extinguished by his brother, a team of five or six labourers using the sprayer, and the road workers. To ensure safety, the burnt grass was swept towards the middle and sprayed again with water. The appellant's employees then left. The appellant alleged the fire flared up again and spread to the mango orchards.
The appeal was dismissed with costs.
Where a party allegedly negligent in starting a fire has witnessed experienced and equipped third parties extinguish the fire and take additional precautions to prevent it reigniting, and those third parties are satisfied that the fire has been extinguished and will not flare up again, a reasonable person in the position of the allegedly negligent party would not foresee that the fire would reignite. Consequently, the first requirement of the test for negligence in Kruger v Coetzee - reasonable foreseeability of harm - is not satisfied, and no liability for subsequent damage can arise.
The court expressly assumed in favour of the appellant that (1) the road workers were negligent in starting and not controlling the fire, and (2) that the fire did indeed flare up again and spread to the mango orchards. These assumptions were made for purposes of analysis but were not findings of fact. The court's approach demonstrates that even making these favourable assumptions, the appellant's claim could not succeed on the application of the Kruger v Coetzee test. The judgment also implicitly recognizes the principle of novus actus interveniens, though not explicitly stated - the intervention of the appellant's experienced personnel who took control of the situation and made their own assessment of safety may be viewed as breaking the chain of causation from the road workers' initial alleged negligence.
This case is of limited significance as it is expressly stated to be "of no precedential significance". It nonetheless illustrates the application of the reasonable foreseeability requirement in the Kruger v Coetzee test for negligence in the specific context of fire damage. It demonstrates that where an initial wrongdoer's potential liability is broken by the intervention of a competent third party who takes over control of a dangerous situation and determines it to be safe, the initial wrongdoer may not be held liable for subsequent damage where reasonable foreseeability cannot be established.
