Murder and Partial Defences (Voluntary Manslaughter) Flashcards
What is the full legal definition of murder (acts reus and mens rea)?
Homicide is the unlawful killing of a reasonable are`ture in being under the Queen’s peace with malice aforethought.
Does the act of medical staff turning off life support absolve the person who inflicting injuries putting the victim in hospital in the first place?
No. This would be irrelevant and the perpetrator would still be liable.
Give the MR of murder.
Tis in the definition is malice aforethought, however has developed to now be the intention to either kill or cause serious harm to the victim.
Give the AR of murder.
The unlawful killing of another human being.
What is oblique/ indirect intent?
Where the death/ serious harm was not D’s intended aim but merely a virtually certain consequence of their actions and it is clear D appreciated this was this case.
What is direct intent in the context of murder?
Direct intent means that death or GBH was D’s aim to purpose.
True or False: The elements of murder must be satisfied even in cases of voluntary manslaughter.
True.
What are the three partial defences to order (which will result in a conviction for voluntary manslaughter if successfully pleaded)?
- Diminished Responsibility;
- Loss of control;
- Suicide Pact
Who has the legal burden of proving all of the elements of diminished responsibility?
The defence have the legal burden to prove diminished responsibility, but the standard of proof is the balance of probabilities.
List the requirements for diminished responsibility to be successfully argued (provided the murder elements have been satisfied).
1) Abnormality of mental functioning; which;
2) Arose from a medically recognised condition; and
3) Substantially impaired D’s ability to understand the nature of their conduct and/or form a rational judgment and/or exercise self control; and
4) Provides an explanation for D’s act or omission in doing the killing.
If all of the above is successfully argued, D cannot be found guilty of murder.
Explain the requirement of a recognised medical condition (for diminished responsibility).
- Usually accepted to be those conditions recognised on the WHO international classification of diseases list. This is however not a closed list.
Explain the requirement of abnormality of mental functioning (for diminished responsibility).
This is usually determined based on the medical evidence given by medical experts at trial.
Give some examples of psychiatric conditions which may constitute a recognised medical condition for the defence of diminished responsibility.
1) Depression;
2) Schizophrenia
3) PTSD
4) Battered persons disorder;
5) Phobic anxiety.
Give some examples of physical conditions which may constitute a recognised medical condition for the defence of diminished responsibility.
1) Alcohol dependency;
2) Diabetes;
3) Epilepsy.
What must the jury consider when asking whether the recognised medical condition provides an explanation for D’s act of killing?
There must be a causal link between D’s recognised medical condition and their conduct which provides an explanation for their act of killing. (in other words there must be a causal link between D’s medical condition and their behaviour).
Explain the relationship between intoxication and recognised medical condition for the purposes of diminished responsibility.
Intoxication alone (provided there is no dependancy related condition) will not excuse D from liability and therefore will not satisfy the medical condition test for diminished responsibility.
However, if the intoxication induced a pre-existing recognised medical condition, this will likely be sufficient. Eg if consuming a large amount of alcohol induced schizophrenia, this would be sufficient. the recognised medical condition must be a cause of D’s actions but need not be the only cause.
Explain the substantial impairment element of diminished responsibility.
The abnormality of mental functioning should impair D’s mental functioning substantially (ie important and weighty). As such, the matter of impairment will be a question on the fact for the jury.
The impairment element refers to the nature in which thew abnormality of mental functioning substantially prevents D to exercise self-control, rational judgment or understand the nature of their conduct.
List the requirements for successfully pleading loss of control.
1) D must lose self-control; and
2) Loss of control must have a qualifying trigger; and
3) A person of D’s sex and age with a normal degree of tolerance and self-restraint and in the circumstances of D might have reacted in the same way or in a similar way that D did.
Explain the burden of proof in relation to loss of control.
Where the defence adduces evidence raising the defence of loss of control, the burden reverts back to the prosecution to disprove the loss of control beyond the reasonable doubt. If the prosecution fails to do so, jury must assume the defence of loss of control has been satisfied.
Define the loss of control element of the loss of control defence.
It must be established that D lost self control. This is subjective and assessed by the jury, but it is not enough to merely ask Ould the reasonable person have lot self control.
In R v Jewell, COA offered guidance indicating. loss of control will be D’s loss of ability to act ‘in accordance with considered judgment, or a loss of normal powers of reasoning’.
Does the loss of control need to be sudden?
- No. Killings which occur in the context of domestic violence where D’s reaction builds up over time, are not excluded from the definition.
- Important to note though that the greater length of time D has to deliberate, the less likely the killing will be deemed to follow a loss of control.
Summarise where it may be deemed there was a loss of control.
1) Where D snaps; and
2) Where their reaction is a response to a culmination of events such as incidents of abuse which occur over time.
Will a revenge killing satisfy the loss of control element for the defence of loss of control?
No. s54(4) CJA 2009 states loss of control defence will not apply where D acted in a considered desire for revenge.
Explain the qualifying trigger elect of the defence of loss of control.
- The qualifying triggers were introduced as the ‘fear’ and ‘anger’ triggers.
- The loss of control must therefore be down to one of these or a combination of both;
- Important to note D cannot rely on these triggers where they have incited the situation to provide them with an excuse to use violence in response.
