• ·Law: X's actions toward Y may constitute homicide, which pursuant to s 277 is unlawful killing of a person. Depending on the circumstances, under s 277 an unlawful (s268) killing is either murder or manslaughter. Killing is defined in s 270 as causing the death of another directly or indirectly by any means. Death is defined under 13C of the Interpretation Act 1984 (WA) as the irreversible cessation of circulation or brain function. A person capable of being killed is defined under s 269 as a person completely proceeded in a living state from their mother.‘Y is a person.
Y is dead’
• Variable for s269: Where an injury is done to an unborn child who then dies after birth it must be established that the prior injuries are a valid cause of death. In the case of Martin v R it was held that a causal link can be drawn between injury to a foetus and the death of that child after birth. Specific reference was made in the case to s 271 where “a child dies in consequence of acts done … by any person before or during birth, the person who did … such act is deemed to have killed the child.”
• Causation – Proof of causation requires satisfaction of both factual and legal elements (Royall; Krakouer) [what you need to look at is the causation between the act and the death, so when you apply the tests, you pick a specific action of the accused. If there is no action, then you look at omission.]
◦
Factual - Generally easy to establish factual causation under the 'but-for' test (Royall). Variable: However, it does not apply in cases of an innocent agent
(White v Ridley) or in cases of omission, unless there was a duty and the actions are reasonable in the circumstances (duties ss 262-267). [Apply to facts by stating very precisely .’but for Y doing specifically this, X would not have done this and hence not died]
◦
Legal – Royall established four tests for legal causation. In difficult cases the operative and substantial cause is best.
