Homicide Flashcards
Elements of murder
Actus Reus: defendant unlawfully killed another human being under the King’s peace; and
Mens rea: Defendant committed the actus reus with intention to kill or cause grievous bodily harm
And no valid defence.
Sentencing for murder
Murder carries a mandatory life sentence. Judge has no discretion in sentencing other than to recommend a minimum terms before a prisoner can be released on licence.
Unlawful killing exceptions
- killing enemy soldiers in battle
- Advancement of justice (although the UK no longer has the death penalty)
- Self-defence: reasonable force necessary to prevent crime or protect self, others or property
Murder
Must be both the factual and legal cause.
Factual - but for the acts or omissions of the defendant, the relevant consequence would not have occurred in the way that it did.
Legal - the defendant’s act must be the substantial cause of the prohibited harm. Does NOT mean it has to be the only or principal cause but it needs to be more than minimal
Is it possible to murder a corpse?
No it is not.
Moment when the brain dies the person will be held to have died.
When does a person come into being?
- Child must be fully expelled from the mother’s body and born alive
- Not necessary for the umbilical cord to be cut
- Case where woman was stabbed in the abdomen - child born prematurely and died: child was not alive when stabbed and therefore could not be murder
“Queen’s peace”
Refers to jurisdiction
Malice aforethought
- intention to kill; or
- intention to cause grievous bodily harm - means ‘serious harm’
Defendant does not need to have any malice nor does it need to be premeditated.
Mercy killing is no defence in English law
Defendant can have malice aforethought even if they kill a person in the spur of the moment.
Principles of intention
- Generally the meaning of intention should be left to the common sense of the jury. However, direct intent is where the consequence is what the defendant, subjectively aims to happen
- Where D’s aim or purpose in acting is something other than death or grievous bodily harm, juries are not entitled to find oblique intent unless they feel sure:
Death or serious injury was a virtual certainty as a result of the defendant’s action; and
The defendant appreciated that
- Judges have said that the need for a Woolin direction will rarely arise. Oblique intention is not intention but evidence of it.
- Motive is not the same as intention but can be used as evidence os intention.
What are the two special defences to murder
Diminished Responsibility
Loss of Control
What type of defence is diminished responsibility?
It is a partial defence - meaning if it is successful defendant is not acquitted but convicted of a lesser offence -> voluntary manslaughter.
Effect of voluntary manslaughter
Mean judge will have discretion in sentencing and the defendant will avoid the mandatory life sentence handed down to those convicted of murder.
Who is the burden on for diminished responsibility?
Burden falls on the defence to prove on the balance of probabilities that the defendant was acting under diminished responsibility.
Is diminished responsibility available as a defence to a charge of attempted murder?
No.
Elements of defence of diminished responsibility
D was suffering from an abnormality of mental functioning which:
(a) arose from a recognised medical condition;
(b) substantially impaired D’s ability to do one of more of the following:
- understand the nature of their conduct
- form a rational judgment
- exercise self-control
(c) and provides an explanation for D’s acts or omissions in doing or being a party to the killing.
Abnormality of mental functioning provides an explanation for D’s conduct if it causes or is a significant contributory factor in causing D to carry out that conduct
Abnormality of mental functioning
A state of mind so different from that of ordinary human beings that the reasonable man would term it abnormal.
Must be CAUSED by the recognised mental condition.
Must not be acting out hatred, jealousy or bad temper
Recognised medical condition
- Can be undiagnosed at the time
- Abnormality must be caused by the recognised medical condition
- Alcohol Dependency Syndrome is a recognised medical condition - but voluntary intoxication is not
Substantial impairment
Greater than trivial impairment of:
- conduct: does not understand what they are doing e.g. boy who kills friend because people come back to life in video games
- rational judgment: delusional, worn down
- exercise self control: devil takes control of him
Provides an explanation
Needs a causal link between abnormality of mental functioning arising from a recognised medical condition and the killing.
BUT need not be the only cause.
Defence can still operate even if alcohol has played a part.
Medical expert evidence: R v Brennan
A judge should withdraw the murder charge from the jury when either the expert medical evidence is uncontested or when there is no other evidence which is capable of rebutting the medical evidence.
Held to be legitimate and helpful for expert psychiatrists to give evidence.
All four elements of the defence are concerned with psychiatric matters.
Three requirements for loss of control
- D must have lost self control
- due to the fear and/or anger qualifying trigger
- a normal person might have acted in a similar way: 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 or in a similar way to D.
Burden of proof for loss of control
Evidential burden to raise the defence.
Burden of proof then rests with the prosecution to disprove it.
- prosecution only need to prove that one of the components is absent for the defence to fail.
Who decides whether the jury can hear the defence?
The judge will decide whether the defence can be put before the jury.
Loss of self-control
Can be assessed by looking at ordinary meaning. Whether the defendant actually lost control is a question for the jury taking into account all of the evidence.
- It need not be sudden, but the jury should consider any delay between provocation and the killing (the longer the delay the less likely the defendant lost control)
- If acting out of a considered desire for revenge the defence will be lost.
