(66 cards)
explain the meanings of different homicides
- Homicide
- Criminal Homicide
- Murder
- Voluntary Manslaughter
- Involuntary Manslaughter
- Reckless Manslaughter
- Gross negligent
- constructive
- Homicide - Not criminal, D doesn’t have an unlawful faultI killed someone, BUT it wasn’t my fault (it was an accidental, valid defence eg. self-defence, or lawful)
- Criminal Homicide - The actus Reus is unlawful killing of a human beingI killed someone, AND the law says I’m to blame for it.
- Murder -Has the intention(knowing it will WANT TO AND KNOW) to kill OR GBHI meant to kill OR seriously hurt them, and I knew it would happen.
- Voluntary Manslaughter - Has the intention(knowing it will) to kill OR GBH . There is ADEQUATE provocationI meant to kill, BUT I might have an excuse or mental condition. (I murdered with partial defence - loss of control, suicide pact, diminished responsibility)
- Involuntary Manslaughter - no intention to kill but irresponsible unlawful actI didn’t mean to kill, BUT I am legally responsible for the death.
- Reckless Manslaughter - foresight(KNOW IT WILL HAPPEN EVEN IF U DONT WANT IT TO) of death or serious injury (eg. arson outside house)I didn’t mean to kill, BUT I knew someone could die and carried on anyway.
- Gross negligent - just doing something you SHOULD do responsibly carelesssly, negligent to HIGH risk of death or serious injuryI didn’t mean to kill, BUT I was super careless in a situation where I should have been responsible.
- constructive - neither foresight nor negligence - just the pure act with relevant mens rea (eg. punch and dies)I didn’t mean to kill, BUT I did something illegal and dangerous, and they died.
murder v voluntary v involuntary (actus reus and mens rea)
Type Actus Reus (Same) Mens Rea (Different)
Murder Unlawful killing of a human being Intention to kill or cause GBH
Voluntary Manslaughter Unlawful killing of a human being Intention to kill/GBH but with partial defence
Involuntary Manslaughter Unlawful killing of a human being No intent to kill/GBH but reckless, negligent, or unlawful act
Actus Reus Criminal Homicide
“an unlawful killing of a human” - actus reus
- killing
- an act or omission (murder (eg. not feeding baby), gross negligent, sometimes recklessness only)
- death of a person
- unbroken chain of causation
- unlawful
- lawful only if accidental or there is a valid defence making it lawful
- You have a choice to refuse treatment tho
- human“in being”
what should actus reus of killing consist ?
- an act or omission (murder (eg. not feeding baby), gross negligent, sometimes recklessness only)
- death of a person
- unbroken chain of causation
-
Factual Causation➔ Apply the “but for” test (R v White ):
- But for D’s conduct, would V have died?
-
Legal Causation➔ D’s act must be a “significant and operative cause” of death (R v Smith [1959]).
- Thin skull rule applies (R v Blaue ) — take your victim as you find them.
-
Novus Actus Interveniens➔ Causation chain can only break if an independent, unforeseeable event occurs.
- Medical negligence: unlikely to break chain unless “palpably wrong” (R v Jordan).
- Victim’s own act: won’t break chain if reasonable and foreseeable (R v Roberts .
- Policy Point➔ “Causation rules in homicide ensure liability accurately reflects moral blameworthiness and autonomy of victims.” (Hart, 1968)
-
Factual Causation➔ Apply the “but for” test (R v White ):
Causation elaboration for homicide
-
Factual Causation➔ Apply the “but for” test (R v White [1910]):
- But for D’s conduct, would V have died?
-
Legal Causation➔ D’s act must be a “significant and operative cause” of death (R v Smith [1959]).
- Thin skull rule applies (R v Blaue [1975]) — take your victim as you find them.
-
Novus Actus Interveniens➔ Causation chain can only break if an independent, unforeseeable event occurs.
- Medical negligence: unlikely to break chain unless “palpably wrong” (R v Jordan [1956]).
- Victim’s own act: won’t break chain if reasonable and foreseeable (R v Roberts [1972]).
- Policy Point➔ “Causation rules in homicide ensure liability accurately reflects moral blameworthiness and autonomy of victims.” (Hart, 1968)
Causation in Homicide Importance with authority
Differentiating Criminal & Non-criminal Homicide using actus reus
➔ “Causation rules in homicide ensure liability accurately reflects moral blameworthiness and autonomy of victims.” (Hart, 1968)
When is a killing considered unlawful in criminal homicide?
➔ A killing is unlawful unless it is (a) accidental or (b) justified by a valid defence (e.g., self-defence, necessity).
➔ Otherwise, the actus reus of homicide is satisfied.
Assisted Dying is a highly debated topic here
2024 Assisted Dying Bill
➔ Parliament voted in favour of advancing legislation (still in early stages) to allow assisted dying for terminally ill adults, not euthanasia.
➔ Patient must self-administer the final act after doctor’s approval.
Airedale NHS Trust v Bland
Topic:
➔ Refusal of Treatment / Withdrawal of Life Support
Offence:
➔ N/A (Medical omission relevant to homicide causation)
Brief Facts:
➔ Doctors sought court approval to withdraw life support from a patient in a persistent vegetative state.
Legal Importance (Ratio/Precedent):
➔ Withdrawal of futile life-sustaining treatment is lawful and not an unlawful killing.
➔ Distinguishes lawful omission from unlawful active killing.
Golden Nugget to Remember:
➔ Stopping life support for brain-dead or vegetative patients = lawful omission, not murder.
R(Nicklinson) v Ministry of Justice
Topic:
➔ Assisted Suicide and Lawfulness of Killing
Offence:
➔ N/A (Challenge to Suicide Act 1961)
Brief Facts:
➔ Applicant with locked-in syndrome challenged the criminalisation of assisted suicide under Article 8 ECHR.
Legal Importance (Ratio/Precedent):
➔ Assisted suicide remains unlawful under the Suicide Act 1961.
➔ Judicial deference to Parliament on reforming assisted dying law.
Golden Nugget to Remember:
➔ No right to assisted dying. Reform must come through Parliament, not courts.
What is a human “in being” as a victim of criminal homicide?
- fetus is not alive yet (R v Poulton) The child must have fully left the birth canal and be capable of breathing.
- but if baby is born and harmed due to womb infections it counts (Attorney-General’s Reference (No. 3 of 1994))
- but only for no intention offenses (eg. manslaughter instead of murder) (R v Senior)
- brain dead is not in being and is the legal definition of death (Airdale NHS trust OR R v Malcherek & Steel) pulling plug is not murder
Direct Intention — Murder
➔ D acts with the aim of killing or causing GBH(Cunningham implied malice). No need for malice aforethought, motive, or premeditation (Vickers; Inglis).
Golden Nugget: It’s what D intends, not why, that matters.
Oblique Intention — Murder
➔ D foresees death or GBH as virtually certain and proceeds anyway (Moloney ➔ Nedrick ➔ Woollin). Foresight is strong evidence of intent, not conclusive proof.
Golden Nugget: Virtual certainty + foresight = jury may infer intention.
Duff’s Test (1990)
Oblique intention
➔ If death/GBH is essential to D’s plan (i.e., D would view the result’s absence as a failure), D intended it.
Golden Nugget: Success = death/GBH must be integral to D’s goal.
Oblique Intention vs Reckless Manslaughter
➔ Murder = foresight of virtual certainty (Woollin). Manslaughter = foresight of risk (Cunningham; R v G).
Golden Nugget: Risk = manslaughter. Certainty = murder.
Difference - Virtual Certainty
Law Commission’s Proposed Classification
➔ 1st degree murder: intention to kill. 2nd degree murder: intention to cause serious injury leading to death.
Golden Nugget: First degree = intent to kill; second degree = intent to seriously injure.
standard murder jury direction
➔ Jury must ask: Did D intend to kill? If not, did D intend serious injury?
Golden Nugget: Kill or cause serious injury — either proves murder.
Elliot’s Critique on Murder Classifications
➔ Current homicide law treats all killers the same; should distinguish between differing culpability (e.g., drug crime killings).
Golden Nugget: Reform homicide to better match moral blame.
R v Vickers
Topic:
➔ Direct Intention — Malice Aforethought
Brief Facts:
➔ D beat an elderly woman causing GBH; she died.
Legal Importance:
➔ Intent to cause GBH suffices for murder; no need for express intention to kill.
Golden Nugget:
➔ Momentary intent to cause GBH = murder.
R v Inglis
Topic:
➔ Direct Intention — Motivation Irrelevant
Brief Facts:
➔ D killed her severely disabled son to relieve suffering.
Legal Importance:
➔ Compassionate motives are irrelevant if death was intended.
Golden Nugget:
➔ Killing “out of love” is still murder if death intended.
R v Moloney
Topic:
➔ Foresight and Intention (Oblique Development)
Brief Facts:
➔ D shot stepfather after a drunken challenge.
Legal Importance:
➔ Foresight of consequences is evidence of intention, not itself intention.
Golden Nugget:
➔ Foresight helps prove, but is not, intention.
R v Nedrick
Topic:
➔ Oblique Intention Development
Brief Facts:
➔ D set fire to frighten someone; child died.
Legal Importance:
➔ Virtual certainty test: Was death virtually certain, and did D realise?
Golden Nugget:
➔ Virtual certainty + D’s awareness = possible intention.
R v Woolin
Back
Topic:
➔ Oblique Intention Final Test
Brief Facts:
➔ D threw baby towards cot; baby died.
Legal Importance:
➔ Foresight of virtual certainty is strong evidence from which intent may be inferred.
Golden Nugget:
➔ Death virtually certain + foresight = strong evidence of intent.
virtual certainty test - “feel sure that death or serious bodily harm was a virtual certainty (barring some unforeseen intervention) as a result of the defendant’s actions and that the defendant appreciated that such was the case.”
When does murder become voluntary manslaughter?
When a defendant committed a voluntary killing, but a partial defence (loss of control or diminished responsibility) reduces murder to manslaughter, making a mandatory life sentence unjust.
