Murder and Voluntary Manslaughter Flashcards
Definition of murder
‘Unlawful homicide’, defined by Lord Coke as ‘unlawfully killing a reasonable person who is in being and under the King’s peace’
Murder - actus reus
- Unlawful
- Killing
- Human being
- Queen’s peace
Murder - mens rea
- Malice aforethought
- Intention to kill or intention to cause grievous bodily harm
Murder - Actus reus: Unlawful
The killing must be unlawful. It will be lawful to kill another if it is:
(a) Killing enemy soldiers in battle
(b) Advancement of justice
(c) Self defence
Murder - Actus reus: Killing
Murder is a result crime which requires the prosecution to show that the defendant caused the death of the victim. The tests of factual and legal causation must be satisfied.
Factual causation
‘but for’ the acts or omissions of the defendant, the relevant consequence would not have occurred in the way that it did (R v White)
Legal causation
The defendant’s act must be the ‘operating and substantial’ cause of the prohibited harm. It does not have to be the only/principal cause, but must be more than minimal (R v Hughes)
Murder - Actus reus: ‘a reasonable person in being’
A person is ‘in being’ when born alive and capable of independent life.
R v Poulton - a child must be fully expelled from the mother’s body and born alive; ‘whether the child was born alive or not depends mainly upon the evidence of medical men.’
R v Reeves - it is not necessary for the umbilical cord to have been cut.
AG-Ref (No 3 of 1994) - A pregnant woman was stabbed in the abdomen, her child was born prematurely and died. The child was not a live person when stabbed and therefore this was not murder.
Murder - Actus reus: under the King/Queen’s peace
R v Adebolajo - Two men killed a soldier in London because he was in the British army. They said they were fighting a war so were not under the Queen’s peace. Now, an offender can generally be tried for murder whether committed if he is a British subject, or, if not a British subject, the murder was committed within England and Wales.
Mens rea - malice aforethought
‘Malice aforethought’ means:
a) Intention to kill (express malice);
(b) Intention to cause grievous bodily harm (implied malice) (R v Vickers
Meaning of ‘grievous bodily harm’
‘Serious harm’ (Saunders)
Important aspects about malice aforethought
- The defendant does not need to have any malice, nor does the act need to be premeditated.
- Mercy killing is no defence in English law (Inglis)
- The defendant can have malice aforethought even if they kill a person in the spur of the moment.
What is diminished responsibility?
- One of the two special defences to murder
- Special defence = it can be used as a defence to murder only
What type of defence is diminished responsibility?
Partial defence - if it is successful, the defendant is not acquitted but convicted of a lesser defence, voluntary manslaughter (Homicide Act 1957, s 2(3)).
What impact does diminished responsibility voluntary manslaughter have on the sentence imposed?
It means the judge will have discretion in sentencing and the defendant will avoid the mandatory life sentence handed down to those convicted of murder (Murder (Abolition of Death Penalty) Act 1965)
Who is the burden on for proving diminished responsibility?
The burden falls on the defence to prove on the balance of probabilities (so a lower standard) that the defendant was acting under diminished responsibility (s 2(2) HA 1957)
What is diminished responsibility not a defence to?
Diminished responsibility is not available as a defence to a charge of attempted murder (R v Campbell)
Diminished responsibility - statutory reference
s 2(1) Homicide Act 1957 (as amended by the Coroners and Justice Act 2009, s 52)
‘(1) A person (D) who kills or is a party to the killing of another is not to be convicted of murder if 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 or more of the things mentioned in subsection (1A), and
(c) provides an explanation for D’s acts and omissions in doing or being a party to the killing.’
‘(1A) Those things are–
(a) to understand the nature of D’s conduct,
(b) to form a rational judgment;
(c) to exercise self control.’
‘(1B) For the purposes of subsection (1)(c), an 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.’
Meaning of an ‘abnormality of mental functioning’
R v Byrne - a ‘state of mind so different from that of ordinary human beings that the reasonable man would term it abnormal.’
Abnormality of mental functioning - a recognised medical condition
- It is sufficient that the defendant was suffering from a recognised medical condition that was undiagnosed at the time of killing.
- It is not enough that the defendant was suffering from an abnormality of mental functioning/has a recognised medical condition. The abnormality must be caused by the recognised medical condition and not something else.
- Alcohol Dependency Syndrome (ADS) is a recognised medical condition.
R v Dowds - Defendant, a binge drinker, stabbed his partner after a night of heavy drinking. He tried to argue dim.responsibility on the grounds of a medical condition, Acute Voluntary Intoxication. He was not arguing that he was an alcoholic (ADS). The trial judge concluded voluntary intoxication could not give rise to the defence.
R v Dowds - reliance on medical conditions recognised in WHO’s International and Statistical Classification of Diseases (ICD) and the American Medical Associations Diagnostic and Statistical Manual (DSM)
CoA noted that both the ICD and DSM recognised a number of medical conditions that would give rise to significant problems if raised as issues in legal cases, such as ‘unhappiness’ and ‘intermittent explosive disorder.’
The DSM itself, in its introduction, warns against a rigid application of the categories of medical conditions to legal issues.
