England In
English law, the
mens rea requirement of murder is either an
intention to kill or an intention to cause grievous bodily harm. In
R v Moloney [1985], Lord Bridge held that intent, as defined in the
mens rea requirement of murder, 'means intent', so the jury should simply use the term
intent legally as they would in normal parlance. Furthermore, he held that for the defendant to have the
mens rea of murder, there must be something more than mere foresight or knowledge that death or serious injury is a "natural" consequence of the current activities: there must be clear evidence of an intention. This element of intention is fulfilled when the defendant's motive or purpose was to cause death or serious bodily harm (also known as 'direct intent') but also when the defendant's motive or purpose was not to cause death or grievous bodily harm but (as held by Lord Steyn in
R v Woollin) death or serious bodily harm was a 'virtual certainty' of the defendant's act, and the defendant appreciated that to be so (also known as 'oblique intent').
United States In most common law jurisdictions, the American Law Institute's
Model Penal Code, and in the various
U.S. state statutes, which have codified homicide definitions, the term has been abandoned or substantially revised. The four states of mind that are now recognized as constituting "malice aforethought" in murder prosecutions are as follows: • intent to kill • intent to inflict serious bodily injury • extremely reckless disregard for the value of human life •
felony murder rule Since there are 4 different states of mind of malice aforethought, it can be hard to find the differences. It is easiest to break these categories up by premeditation, express malice and reckless endangerment, or implied malice. Intent to kill or to inflict serious bodily injury would be considered express malice. This does not mean that the accused made a plan far in advance, but it could even be in the moment of the crime. If the person did the action knowing it would hurt or kill the other person, there was express malice involved, which is a form of malice aforethought. As stated above, malice aforethought does not require that the person accused premeditated to hurt a person, but that they knew their actions could lead to someone's harm. This is implied malice, which requires that a person knowingly did an act that they knew was dangerous, and acted without concern for other people's safety, even if not premeditated. Hence, intention can also be found where the perpetrator acts with gross recklessness showing lack of care for human life, commonly referred to as "
depraved-heart murder", which can be treated as
second-degree murder due to the presence of implied malice. Lastly, murder committed during the commission of or while in flight from a felony or attempted felony is termed
felony murder. Notably, the principle of
transferred intent causes an accused who intended to kill one person but inadvertently killed another instead to remain guilty of murder. The intent to kill the first person suffices.
Australia Malice aforethought, also known as mens rea, is still used in the criminal justice system today when trialing for murder. The term is a catch-all phrase that encompasses all the states of mind that are sufficient
mens rea for murder. Most Australian
jurisdictions require some degree of actual awareness of the resulting consequences of the accused's own actions to justify a
murder conviction. The
High Court of Australia affirmed that there is a spectrum of
mens rea ranging from intention to kill to reckless indifference that would be relevant in securing a murder conviction. However, the High Court ruled that it was not necessary to prove malice aforethought in a manslaughter conviction. The Full Court of the
Supreme Court of Victoria distinguished between the two classes of manslaughter. They were manslaughter by reckless indifference and manslaughter by criminal negligence in
R v Nydam in which malice aforethought was definitively ruled out as an element in a charge of manslaughter by criminal negligence. ==References==
