murder, diminished responsibility and loss of control Flashcards
case of martin (depressive illness/paranoia) (stage1: abnormality of mental functioning)
F: Martin suffered paranoid delusions, from childhood trauma, specifically sexual abuse which caused him to believe he was at risk of being violated by the burglars. his mental state, made him react more violently than the average person. he was suffering from an abnormality of mind causing the overreaction.
H: Paranoid personality disorder and depression can be inherent causes of DR
case of cambell (epilepsy) (stage1: abnormality of mental functioning)
F: D picked up a hitchhiker and attacked her when she refused his sexual advances.
H:At the time of the killing D had been suffering from an abnormality of mind of such significance (epilepsy and frontal lobe damage) so that it diminished his responsibility for the act he carried out
case of tandy (alcoholism as a disease or injury) (stage1: abnormality of mental functioning)
F: D was an alcoholic for a number of years. She strangled her 11 yr old daughter when she told her mother her 2nd husband had sexually assaulted her. She had been drinking vodka which was not her usual drink.
H: Abnormality of mind may include a disease caused by long-term alcoholism and/or drug addiction. However, D had not proved that she was suffering from long-term alcoholism, as she had not proved that she could not resist the first drink of the day.
case of Dietschmann ( alcoholism as a disease or injury) (stage1: abnormality of mental functioning)
F: D was taking anti-depressants following the death of his aunt (with whom he was having a sexual relationship). At a party he was drunk and attacked V when he thought he had damaged a watch given to him by his aunt. V died from the attack.
H:DR could now be successful even if D would not have killed had he been sober. The abnormality of mind must nevertheless have been the substantial cause of the impaired mental responsibility leading to the killing.
case of Dowds (alcoholism as a disease or injury) (stage1: abnormality of mental functioning)
binge drinking cannot in itself be an AMF
case of ahluwalia and thornton (BWS as a disease) (stage1: abnormality of mental functioning)
CA allowed their appeals against a murder conviction on the basis of such a condition
case of byrne (stage 2: substantial impairment of defendants ability)
F:Sexual psychopath who strangled a young woman and mutilated the body
H:His impulses were not irresistible but extremely difficult to control. In this case it was sufficient to prove substantial impairment but will depend on the jury in each case
Golds (2016) (stage 2: substainal impairment of defendants ability)
substantial means “distinctly more than just past the trivial” but judge does not need to explain the meaning of substantial to a jury, they can decide this for themselves
Dietschmann outcome (stage 3-A significant contributory factor to the killing)
The abnormality needs to be a substantial cause of the killing but doesn’t have to be the SOLE cause
case of osbourne (stage 3-A significant contributory factor to the killing)
F: D was smoking cannabis with friends and saw V walking with an Asian woman. A fight broke out. V punched D in self-defence and left. D grabbed a plank of wood and attacked V from behind.
H: It is possible for ADHD to support a defence of diminished responsibility however in this case the ADHD suffered by D did not substantially impair his mental responsibility for his actions at the time of the killing
what is the AR of Murder
“the unlawful killing of a human being under the queen’s peace”
what is the definition of murder
the unlawful killing of a human being with malice aforethought within the queen’s peace (lord coke)
what are the issues relating to the AR of murder
causation and omissions
what is the queen’s peace
killing of the enemy in the course of war- not murder.
what is the problem with the definition of death
there is no single legal definition of death but life is recognised by the brain stem activity and death occurs when brain stem activity ceases
explain the case of Malcherek and Steel
F: D stabbed his wife repeatedly in the stomach she was put on life support but after a number of tests showed she was brain-dead the machine was switched off.
H: this does not break the chain of causation to D
explain the case of AG Ref (No 3 of 1994)
F: men stabbed his pregnant girlfriend who then gave birth prematurely to the baby. the baby and the mother later died.
H: there was no requirement that the person had to be ‘in being’ when the act causing death was perpetrated (therefore if the baby is born alive but then died D could be charged with murder)
what is the definition of a human being
someone born breathing
