Homicide Flashcards
What are the Elements of Murder?
- Actus Reus : Unlawfully killing a person in being under the King’s Peace.
- Mens Rea : Malice aforethought.
A person is brought into being when they are fully expelled from their mother’s body.
What is Malice Aforethought?
The intention to kill or cause greivous bodily harm (“GBH”).
What are the Special Defences to Murder?
- Loss of Control.
- Diminished Responsibility.
A Special Defence is a Partial Defence available only against Murder. Neither are applicable against Attempted Murder.
What is Loss of Control?
- The Actus Reus arose from a loss of self-control due to a Qualifying Trigger; and, in the same circumstances
- A normal person of the Defendant’s age and sex might have behaved similarly.
It falls on the Prosecution to disprove beyond a reasonable doubt.
What constitutes a Loss of Control?
Actual loss of one’s ability to think clearly and make rational decisions.
What is a Qualifying Trigger?
- Fear of serious violence.
- Things said or done of an extremely grave nature, justifiably causing a sense of being seriously wronged.
Judged objectively based on modern British norms and values.
Sexual infidelity, considered revenge, and violent pretenses do not apply.
What is Diminished Responsibility?
- The Defendant’s abnormality of mental functioning, caused by a recognised medical condition;
- Substantially impairs their ability to understand their conduct, form rational judgments, or exercise self-control.
It falls on the Defence to prove on the balance of probabilities.
What is an Abnormality of Mental Function?
A state of mind so far from ordinary that the reasonable man would term it abnormal.
What is the Impact of Intoxication?
- It may undermine arguments for the presence of Mens Rea.
- It is irrelevant to the objective aspects of the Loss of Control Defence.
- It is only relevant in a Diminished Responsibility Defence if it stems from addiction.
This assumes the Intoxication was voluntary.
In a Loss of Control Defence where the Defendant is an addict, that attribute may given in the Normal Person Test, but sobriety and ordinary levels of tolerance and self-restraint would still prevail.
What are the Elements of Voluntarily Manslaughter?
- Actus Reus : Unlawfully killing a person in being under the King’s Peace.
- Mens Rea : Malice aforethought.
With a Special Defence applying.
What are the Two Types of Involuntarily Manslaughter?
- Constructive Manslaughter.
- Gross Negligence Manslaughter.
What are the Elements of Constructive Manslaughter?
- Actus Reus : Performing a criminal, dangerous act that causes another to die.
- Mens Rea : Intention to perform the relevant act.
The act cannot be an omission.
The act must be intrinsically unlawful. It cannot be unlawful because it was negligently done, e.g. poor driving.
For Constructive Manslaughter, what constitutes a Dangerous Act?
One that a sober and reasonble person appreciates subjects others to, at least, the risk of some harm.
What are the Elements of Gross Negligence Manslaughter?
- Actus Reus : Breaching a duty of care, where such breach carried an obvious, lethal risk at the material time that actually materialised.
- Mens Rea : Gross Negligence.
What constitutes Gross Negligence?
Negligence so serious that it shows a disregard for life and deserves criminal punishment.
