James died following Rosieâ€™s attack giving rise to potential liability for murder. The actus reus
of murder is unlawful killing of a reasonable person within the Kingâ€™s peace.
This necessitates a causal nexus between Rosieâ€™s attack and Jamesâ€™ death. Factual causation requires that death would not have occurred â€˜but forâ€™ the defendantâ€™s actions.
This is satisfied as Rosieâ€™s attack set in motion a chain of events that resulted in Jamesâ€™ death. However, factual causation only acts as a preliminary filter to eliminate unconnected events; the actus reus
of murder requires that legal causation is also established. Legal causation isolates the most culpable factual cause as the basis for criminal liability. The fact that Rosieâ€™s attack was not the most immediate cause of death is immaterial; following Pagett
, the defendantâ€™s act need not be the sole or even the main cause of death provided it is a
Rosie may argue that the accidental disconnection of Jamesâ€™ life-support system is a â€˜new and overwhelmingâ€™ cause of death that renders her contribution insignificant,
particularly as there is evidence that James would have recovered from her attack. The prosecution may challenge this by claiming that cessation of life-support was characterised as an omission in Bland
and only a positive act can break the chain of causation. However, Bland
can be distinguished as the accidental removal of life-support by an unauthorised and unqualified person is not analogous to a medically-sanctioned cessation of artificial support thus Rosie will establish that the cleanerâ€™s negligence was a positive act thus could potentially break the chain of causation. Irrespective of this, legal causation will be established as it is a policy-driven area that attributes criminal responsibility in line with blameworthiness. The defendantâ€™s wrongdoing rendered the victim vulnerable to deficiencies in treatment thus errors should not absolve the defendant of liability
unless they render the defendantâ€™s contribution wholly insignificant
and, without Rosieâ€™s attack James would not have been on life-support and vulnerable to its termination. This is a particularly pressing argument given that even deliberate cessation of life-support will not break the chain of causation.
As such, Rosieâ€™s attack remains the legal cause of death and the actus reus
of murder is established notwithstanding the accidental disconnection of life-support. The mens rea
of murder is malice aforethought, defined as intention to kill or cause grievous bodily harm.
Rosieâ€™s attack on James was not done with the express purpose of causing death
thus direct intention to kill is not established. If Jamesâ€™ death was a virtually certain consequence of Rosieâ€™s attack and she realised this was the case then oblique intention will be established.
However, Rosie may argue that death was not a virtually certain consequence of being struck about the head with a vase as Jamesâ€™ death was not the direct result of this but occurred because of later events. If this is successful, the prosecution will have to base liability on implied malice (intention to cause grievous bodily harm). Rosie struck a deliberate blow with a lamp, a hard and heavy object, to Jamesâ€™ head, a vulnerable part of the body. As such, the intention to cause grievous bodily harm (defined as â€˜serious harmâ€™)
is established and this satisfies the mens rea
for murder even though the defendant sought to cause injury not death. As the actus reus
and mens rea
for murder are established, Rosie will be liable unless she can rely upon a defence to reduce her liability to murder or obtain an outright acquittal. The Homicide Act 1957 contains two partial defences that could reduce Rosieâ€™s liability to voluntary manslaughter: diminished responsibility
Section 2 provides that the defence is available to defendants who are suffering from an abnormality of mind arising from specified causes that substantially impairs their mental responsibility for the acts leading to death. Rosie was suffering from depression and her history of sexual abuse rendered her likely to resort to violence when placed in abusive situations where her self-esteem was eroded thus may be able to establish a defence of diminished responsibility. This will establish an â€˜inherent causeâ€™ of her condition
but the questions remains as to whether this mental condition would amount to an â€˜abnormality of mindâ€™. This has been defined as a state of mind that is so far removed from the ordinary that a reasonable person would consider it abnormal.
The question for the jury, then, is whether Rosieâ€™s depression and background have caused an abnormality of mind that was operative at the time of the killing. Diminished responsibility confers great discretion on the jury that can be exercised in the defendantâ€™s favour if their sympathy is roused so the success of this defence hinges on whether they perceive Rosie as a vulnerable woman who was exploited and rejected by her employer or as a manipulative and avaricious schemer who set her sights on marrying a wealthy man and struck out when her ambitions were thwarted. The psychiatric evidence suggests the former but the damning evidence of her former partner suggests the latter thus the success of this defence is somewhat uncertain for Rosie. As diminished responsibility may not provide a defence, Rosie may consider reliance on provocation. Section 3 provides a defence for a defendant who was provoked, by things said or done, to lose control in circumstances that would have provoked a reasonable man to act in the same was as the defendant. This gives rise to a two-stage test. The first limb of the test is subjective and asks whether the defendant suffered a â€˜sudden and temporaryâ€™ loss of control.
This requires temporal proximity between the provocative incident and the defendantâ€™s response; anything else is indicative of revenge or planned killing. Here, Rosie is enraged by the email and confronts James, which could be indicative of a planned attack.
However, Jamesâ€™ response in firing Rosie was the â€˜final strawâ€™
which elicited a violent response, using a weapon that was readily to hand, thus establishing the requisite immediacy of reaction to satisfy the subjective limb. However, Rosie must now establish that a reasonable man would have been provoked and acted as she did in attacking James. This objective test is modified by certain characteristics of the defendant being attributed to the reasonable man.
There is uncertain in case law as to which characteristics of the defendant should be given to the reasonable man. In Smith
, the House of Lords held that any characteristics that affected the defendantâ€™s ability to exercise control should be attributed.
Following this, the reasonable man would be a woman of Rosieâ€™s age with a love of children and desire to marry that was recently (and cruelly) thwarted. The reasonable man would share Rosieâ€™s history of abuse and depression. If her allegation of rape is true (although it seems inconsistent with her desire to marry James) the reasonable man would also be the victim of a recent rape. Equipped with these characteristics, the reasonable man could hardly fail to respond as Rosie did and the defence of provocation would be established. However, doubts have been expressed about Smith
. The Privy Council held that it was wrong to attribute so many characteristics to the reasonable man as this converted an objective test into a subjective one.
This is only persuasive authority in this jurisdiction but subsequent Court of Appeal decisions have followed the Privy Council approach of attributing only characteristics that explain the gravity of the provocation rather than the broader approach in Smith
As such, the reasonable man would be a woman of Rosieâ€™s age who had recently been dismissed from her post. It would not taken into account her thwarted marital aspirations or history of abuse and depression. As such, it is far less likely that provocation will provide a successful defence for Rosie. As the availability of partial defences is uncertain, Rosie may plead automatism, on the basis of her â€˜trance-like stateâ€™, which would result in an acquittal. Automatism requires that actions were rendered involuntary as a result of some external event
and has included post-traumatic stress induced by rape.
Again, this is contingent upon the truth of Rosieâ€™s allegation. Moreover, if the judge rules that the dissociative state arose not from an external cause
but from internal cause, such as depression, she will have established a defence of insanity.
This is not a popular strategy amongst defendants; many prefer to plead guilty than be found â€˜not guilty by reason of insanityâ€™. This is attributable to the social stigma attached to insanity and also the ability of the judge to order indefinite detention in a secure hospital, although the judge has discretion to make alternative orders
even in respect of murder.
Overall, reliance on automatism will not be a sound strategy for Rosie as it carries a risk that the court will reject this and find insanity. Overall, Rosieâ€™s prospects are not favourable. Liability for murder is established and there is no clear-cut line of defence that suggests that she will be acquitted or have her liability reduced to manslaughter.
