Homicide Flashcards
When will murder become voluntary manslaughter?
Where D commits AR and MR of murder but can rely on either loss of control or diminished responsibility as a special defence to murder
These two partial defences can only be used for murder
What are the burden of proofs for loss of control and diminished responsibility?
- Loss of control = prosecution to prove beyond reasonable doubt that partial defence does not apply
- Diminished responsibility = defence must prove on balance of probabilities that partial defence applies
DR is one of few instances in criminal law where burden of proof is with defence
Defence must prove Diminished responsibility on a balance of probabilities
Prosecution (i.e. the law) must prove that loss of control does not apply beyond reasonable doubt
Will DR or LOC act as complete defences?
No - only partial so D is not acquitted but also not given a mandatory life sentence; judge has discretion in sentencing
Given lesser charge for voluntary manslaughter
In what order should defences be considered?
- Complete defence (would lead to acquittal)
- Partial defence (would not)
What discretion does judge have on sentencing murder?
None other than recommending minimum term before prisoner can be released on licence
What is the AR of murder?
- Unlawful - lawful killing inc killing enemies in war, death penalty, self-defence
- Killing - factual and legal cause of death
- of a Human Being - must be after child fully expelled from body and before brain dies (cannot kill corpse)
- Under the King’s Peace - means can be tried for murder wherever committed if British subject, or if not, if committed in E+W
What is the MR of murder?
- Malice aforethought - does not need to have malice nor does it need to be premeditated
- Intention to kill or intention to cause GBH (serious harm - key principles of intention apply (common sense of jury etc.)
Mercy killing is no defence in English law
When can juries find oblique intention for murder if D’s aim or purpose is something other than death or GBH?
Will rarely arise
Not unless they are sure that:
- Death or serious injury was a virtual certainty as a result of D’s actions (obj)
- D appreciated that (subj)
Is diminished responsibility available for a charge of attempted murder?
No
Who has the burden of proof and what is it for diminished responsibility?
Burden on defence to prove on balance of probabilities that D was acting under diminished responsibility
What are the 4 requirements of diminished responsibility?
- (D is suffering from) Abnormality of mental functioning
- (which arose from) recognised medical condition
- (which had a) Substantial (more than trivial) impairment of D’s ability to do one or more things
- (and) Provides an explanation for D’s acts/omissions
When will a D be considered to suffer from an ‘abnormality of mental functioning’?
If they had a state of mind so different from that of ordinary human beings that the reasonable man would term it abnormal
Must D be diagnosed with the medical condition at time of killing?
No - can be undiagnosed
Must the abnormality of mental functioning be caused by the medical condition or do the two merely have to exist?
Must be caused by medical condition and not something else (hatred, temper etc.)
Does the medical condition requirement allow intoxication to be run as a defence?
Alcohol Dependency Syndrom (ADS) is a recognised medical condition, but voluntary intoxication remains unchanged
What ‘things’ are included in ‘substantial impairment of D’s ability to do one or more things’?
I.e. What is the thing which D’s ability to do is impaired?
- Understand nature of D’s conduct - does not understand a human life cannot be revived like a video game
- Form a rational judgement - a depressed man kills terminally ill spouse at her request as he found it progressively more difficult to stop her repeated requests dominating thoughts
- Exercise self-control - a man says the devil takes control of him implanting a desire to kill which must be acted on
What does the requirement of ‘provides an explanation for D’s acts/omissions’ mean in practice?
There must be a causal link between abnormality of mental functioning arising from recognised medical condition and killing must be established
Need not be only caused
Can diminished responsibility still run if alcohol has played a part?
Yes
How important is medical evidence in overturning a conviction on diminished responsibility?
Very - if uncontested, medical evidence should mean murder charge should be withdrawn
Where lies the burden of proof for loss of control and to what extent must it be proven?
- With the prosecution
- Must prove that only one one component is absent for defence to fail!
What are the three requirements for a loss of control defence?
- 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 to D
When is there less likely to be a ‘loss of control’ in terms of desire or timing?
1st requirement of LOC
- Where D acted out of a considered desire for revenge
- Where there is a longer delay between provocation and killing (but need not be sudden)
When will there be a fear trigger?
2nd requirement of LOC (hereon)
Where the D has a serious fear of violence
Cannot rely on fear trigger if incited by D
