Definition
The Monument of Negligence
Culpable homicide: the unlawful negligent causing of the death of another human being.
Culpable homicide = unlawful + negligent + causing + death + of another human being.
The Four Pillars
- UNLAWFULNESS — same requirements as murder
- NEGLIGENCE — the fault element (not intention)
- CAUSATION — same but-for and proximate cause tests apply
- DEATH OF ANOTHER HUMAN BEING — same as murder
The Key Difference
The only difference from murder is the fault element. Murder requires intention; culpable homicide requires only negligence. Nobody here intends to kill — yet people still die.
Negligence
The Reasonable Person Observatory
The three-step objective test for criminal negligence.
Three Telescopes
- (1) Would a REASONABLE PERSON in the accused's position have foreseen the reasonable possibility of the result?
- (2) Would a reasonable person have taken STEPS to guard against it?
- (3) Did the ACCUSED FAIL to take those steps?
Negligence is objective — measured against the reasonable person (the classic Kruger v Coetzee formulation, applied in criminal law in Ngubane), NOT the accused's own beliefs or capacity.
The death must be foreseeable
For culpable homicide the DEATH ITSELF — not merely some harm — must have been reasonably foreseeable (Van As). Most cases arise from carelessness: road, industrial or medical accidents, where the accused misses warning signs the reasonable person would have seen.
Key Cases — Negligence
S v Ngubane1985 (3) SA 677 (A)Applies the objective reasonable-person test for criminal negligence: foreseeability, preventability, and failure to take steps.
Facts. The accused drove a vehicle that was involved in a fatal accident. The question was whether the standard for negligence in culpable homicide required subjective foresight or an objective test.
Legal question. What is the correct test for negligence (culpa) in South African criminal law?
Judgment. The Appellate Division confirmed the objective bonus paterfamilias standard for criminal negligence. The accused's subjective appreciation is irrelevant to the negligence enquiry — it is what a reasonable person would have done that matters.
Significance. The definitive statement of the three-step negligence test in SA criminal law. This is the test for culpable homicide and any other crime requiring culpa. The test is always objective — measured against the reasonable person, not the accused's actual beliefs.
Exam tip. Memorise the three-step test: (1) would a reasonable person have foreseen? (2) would a reasonable person have taken precautions? (3) did the accused fail? All three must be satisfied. Contrast with dolus eventualis: negligence asks "should have foreseen"; dolus eventualis asks "did foresee and proceed regardless".
S v Van As1976 (2) SA 921 (A)For culpable homicide the death itself must be reasonably foreseeable — foreseeability of some lesser harm is not enough.
Facts. After police arrested a man at night, several of his small children scattered into the cold and dark. The police made a limited search but failed to find one child, who later died of exposure. They were charged with culpable homicide for the death.
Legal question. Were the police negligent — would a reasonable person have foreseen the possibility of the child's death and taken steps to prevent it — so as to be liable for culpable homicide by omission?
Judgment. The Appellate Division held that, although the police ought to have searched further, the child's death from exposure was not reasonably foreseeable on the facts, so negligence in respect of the death was not established and the culpable-homicide conviction could not stand.
Significance. A leading authority on reasonable foreseeability in negligence and on culpable homicide by omission. Often paired with Ngubane on the negligence test.
Exam tip. Use Van As for the reasonable-foreseeability requirement: the death itself — not merely some harm — must be reasonably foreseeable. Separate the factual duty to act from foreseeability of the fatal result.
Causation
The Avenue of Foreseeability
Same causation test as murder — but foreseeability connects to negligence.
Warning Signs
The Avenue is lined with warning signs: DANGER AHEAD / REASONABLE PERSON WOULD NOTICE / TAKE PRECAUTIONS. The accused drives past them without stopping.
But-For Then Proximate
Factual causation: but for the accused's conduct, would the victim have died? Legal causation: was the accused's negligence the proximate cause of the death?
Exam trap: in culpable homicide, the accused's failure to take precautions (the negligence) must cause the death. If the death would have occurred regardless of the precautions, there is no causal link.
Distinction
The Bridge to Murder
The Bridgekeeper's question separates culpable homicide from murder.
The Bridgekeeper
"Did the accused actually foresee the possibility of death?" If NO → remain in Culpable Homicide Boulevard. If YES + reconciliation → proceed to Murder District.
Should have foreseen (but did not) = negligence = culpable homicide. Actually foresaw + proceeded regardless = dolus eventualis = murder.
The Dolus Eventualis Gate
The Gambler stands halfway across the bridge. Conscious foresight of the possibility of death + reconciliation with that outcome takes the accused across the bridge into Murder District.
Exam Comparison
- CULPABLE HOMICIDE: Objective "should have foreseen"
- MURDER (dolus eventualis): Subjective "actually foresaw + proceeded regardless"
Exam trap: the distinction is subjective vs objective foresight. "He should have known better" = negligence. "He knew it could happen and did it anyway" = dolus eventualis.
