Kembaraxtra-Case Law- R v Cato (1976) - Unlawful Act Manslaughter
Citation: R v Cato (1976) CA
Facts:

Defendant (D) injected the Victim (V) with heroin multiple times at V's request over an evening.
The Victim (V) suffered respiratory failure due to the intoxication and died.

Issue:

Holding:

Reasoning:

Unlawful Act: Although administering heroin per se is not a specific offense, the unlawful act causing death was established through:
- Possession of heroin (an offense).
- Administering a noxious substance (an offense).
Causation: Lord Widgery CJ stated that for causation to be established:
- The heroin injection must be a cause of death.
- The contribution to death does not need to be substantial, and must merely be outside the "de minimis" (minimal) range.
- The injection must have effectively accelerated the victim's death.

Key Principles/Significance:

This case clarifies that the "unlawful act" element of unlawful act manslaughter does not require the act itself to be directly related to the resulting harm, as long as the act is illegal in some form.
Cato illustrates the threshold for causation in unlawful act manslaughter, with the de minimis range test, where the act doesn't need to be the principal cause of death.
