,Mahlangu v Ngubane: Analysis of Wrongfulness and Negligence in South African
Delict Law
Introduction
In South African delictual law, a person can only be held liable for patrimonial
(financial) loss if certain legal requirements are satisfied. These include conduct,
wrongfulness, fault (either negligence or intention), causation, and harm. This
analysis concentrates on two central components—wrongfulness and negligence—
within the context of the dispute between Mr Mahlangu and Ms Ngubane. While they
are closely linked, each element involves a separate legal test. The purpose of this
discussion is to evaluate whether Ms Ngubane can be held legally liable for the
destruction of Mr Mahlangu’s plantation based on these principles.
1. Differentiating Wrongfulness and Negligence
1.1 Wrongfulness
Wrongfulness relates to whether conduct infringes upon a legally protected interest in a
way that society finds unacceptable. Unlike fault, wrongfulness focuses on the nature
of the act, not the actor’s mental state.
In the context of omissions (failures to act), there is no automatic assumption of
wrongfulness. To establish liability, it must be demonstrated that the defendant was
under a legal obligation to act and failed to do so.
A significant precedent here is the case of Minister van Polisie v Ewels 1975 (3) SA
590 (A). The court explained that an omission is wrongful if it violates the community's
legal convictions (the boni mores). Specifically, if someone is in a position to prevent
foreseeable harm and societal values expect them to do so, failing to act may be
considered wrongful.
Applying this to Mahlangu v Ngubane, the issue is whether Ms Ngubane's failure to
take reasonable measures (for instance, failing to manage a hazardous situation such
, as an uncontrolled fire, loose livestock, or dangerous chemicals) constitutes a violation
of her legal duty. If her omission unjustifiably encroached upon Mr Mahlangu’s
property rights, then wrongfulness may be established.
1.2 Negligence
Negligence relates to fault and is typically assessed by using the reasonable person
test. The inquiry is whether a hypothetical reasonable person, in the defendant’s
situation, would have anticipated the potential harm and taken steps to avoid it.
This principle is thoroughly explained in the landmark decision of Kruger v Coetzee
1966 (2) SA 428 (A). The court stated that negligence exists where:
1. A reasonable person in the same position would foresee the likelihood of harm
occurring;
2. That person would act to prevent the harm; and
3. The defendant failed to take such preventive action.
In the Mahlangu matter, the question is whether Ms Ngubane ought to have reasonably
foreseen the risk of damage to her neighbour’s plantation. For instance, if she started
a fire for land-clearing purposes without monitoring it properly, or if she knew her
animals regularly escaped and could cause destruction, such a scenario may point to
negligent conduct.
2. Application of Principles to Mahlangu v Ngubane
While the exact facts of the case are not detailed here, it can be assumed for the
purpose of analysis that Mr Mahlangu’s property was damaged by something that Ms
Ngubane had the responsibility to control—for example, an open fire, pollution, or
roaming livestock.
