Q

what should actus reus of killing consist ?

A
  • 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)

Q

What is a human “in being” as a victim of criminal homicide?

A

  3. but only for no intention offenses (eg. manslaughter instead of murder) (R v Senior)
  4. 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

Q

Direct Intention — Murder

A

Q

Oblique Intention — Murder

A

➔ 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.

Q

Duff’s Test (1990)

A

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.

25
Loss of Control — Overview
➔ Under s.54 Coroners and Justice Act 2009: Loss of self-control due to qualifying trigger + reasonable person test. Focuses on genuine emotional overwhelm, not revenge or premeditation.
26
Diminished Responsibility — Overview
➔ Under s.52 Coroners and Justice Act 2009: Killing due to a recognised medical condition that substantially impaired D’s mental functioning and explained the killing.
27
Loss of Control vs Diminished Responsibility
➔ Loss of control: emotional loss of control triggered by external events. ➔ Diminished responsibility: internal mental disorder substantially impairing D’s abilities.
28
R v Duffy
Topic: ➔ Loss of Control — Meaning of Losing Control Brief Facts: ➔ D killed abusive husband after prolonged mistreatment. Legal Importance: ➔ Loss of control = being "so subject to passion as to not be master of one's mind." Golden Nugget: ➔ Loss of temper ≠ loss of control; must lose mental dominance.
29
R v Goodwin
Topic: ➔ Loss of Control — Frenzied Attack Brief Facts: ➔ D violently attacked V after losing temper. Legal Importance: ➔ Mere frenzied or disproportionate violence does not prove loss of control. Golden Nugget: ➔ Not every violent outburst qualifies as loss of control.
30
R v Dawes, Hatter, Boyer
Topic: ➔ Loss of Control — Revenge and Judicial Role VOLUNTARY MANSLAUGHTER Brief Facts: ➔ D killed after a plan/revenge mindset developed. Legal Importance: ➔ Loss of control defence fails if D acts out of a considered desire for revenge. ➔ Judge decides whether sufficient evidence exists for jury. Golden Nugget: ➔ Revenge ≠ loss of control. Judge controls evidence stage.
31
R v Ahluwalia
Topic: ➔ Loss of Control — Delay in Reaction Brief Facts: ➔ D killed abusive husband after enduring years of violence; reaction was delayed. Legal Importance: ➔ Loss of control need not be sudden, but longer delay = less likely defence will succeed. Golden Nugget: ➔ Delay weakens but does not destroy loss of control claim.
32
R v Johnson
Topic: ➔ Loss of Control — Initial Aggressor Brief Facts: ➔ D provoked violence but V retaliated violently. Legal Importance: ➔ D can still claim loss of control even if he started trouble, if retaliation caused loss. Golden Nugget: ➔ Provoking V doesn't bar defence if V's response triggers true loss of control.
33
R v Clinton
Topic: ➔ Loss of Control — Sexual Infidelity and Triggers Brief Facts: ➔ D killed wife after revelation of sexual infidelity and taunts. Legal Importance: ➔ Sexual infidelity can be considered if it forms part of the context, even though not on its own a qualifying trigger. Golden Nugget: ➔ While s.55(6)(c) expressly excludes sexual infidelity as a qualifying trigger, the Court of Appeal in R v Clinton held that it may be considered where it forms part of a wider context of circumstances giving rise to a justifiable sense of being seriously wronged. Therefore, while sexual infidelity alone is insufficient, it is not always entirely excluded from consideration.
34
R v Bowyer
Topic: ➔ Loss of Control — Excuse vs Real Trigger Brief Facts: ➔ D burgled V and killed him after V insulted D. Legal Importance: ➔ If D uses V’s conduct as an excuse for killing, no qualifying trigger. Golden Nugget: ➔ Excuse ≠ qualifying trigger.
35
R v Myles (provocation to loss of control)
Topic: ➔ Loss of Control — Third Party Triggers Brief Facts: ➔ Trigger involved fear for another person’s safety, not D personally. Legal Importance: ➔ Third-party threats can be qualifying triggers. Golden Nugget: ➔ Fear for others also valid trigger.
36
R v Clegg
Topic: ➔ Loss of Control — Fear of Violence and Excessive Force Brief Facts: ➔ Soldier fired fatal shot after danger had passed. Legal Importance: ➔ Force must be reasonable for self-defence; under loss of control, excessive reactions still focus on loss of control, not perfect judgement. Golden Nugget: ➔ Excessive reaction doesn't cancel out loss of control trigger. contrary to self defence - shld be proportional
37
R v Asmelash
Topic: ➔ Loss of Control — Normal Person Standard Brief Facts: ➔ D was intoxicated during killing. Legal Importance: ➔ Loss of control assessed against a normal sober person of D’s age and sex; voluntary intoxication disregarded. Golden Nugget: ➔ Drunkenness not considered when assessing normal tolerance. --- can use diminished responsibility for abnormal cases
38
R v Blackman
Topic: ➔ Diminished Responsibility — Armed Forces Context Brief Facts: ➔ Marine killed a wounded insurgent; argued PTSD and adjustment disorder. Legal Importance: ➔ Recognised medical condition can reduce murder to manslaughter. Golden Nugget: ➔ Mental disorders from extreme environments may support diminished responsibility.
39
R v Dowds
Topic: ➔ Diminished Responsibility — Voluntary Intoxication not alcoholism Brief Facts: ➔ D killed partner while drunk. Legal Importance: ➔ Voluntary acute intoxication not a recognised medical condition for diminished responsibility. Golden Nugget: ➔ Getting drunk ≠ medical condition.
40
R v Wood
Topic: ➔ Diminished Responsibility — Alcoholism Brief Facts: ➔ D killed after drinking binge; had alcohol dependency syndrome. Legal Importance: ➔ Alcohol dependency syndrome can amount to a recognised medical condition. Golden Nugget: ➔ Alcoholism (not just drunkenness) can support diminished responsibility.
41
R v Gittens
Topic: ➔ Diminished Responsibility — Depression Brief Facts: ➔ D killed wife and stepdaughter while suffering severe depression. Legal Importance: ➔ Depression can amount to a recognised medical condition under diminished responsibility. Golden Nugget: ➔ Depression can substantially impair D’s mental functioning.
42
Salim v Public Prosecutor
Topic: ➔ Diminished Responsibility — Premeditation and Mental Disorder Brief Facts: ➔ D killed ex-girlfriend with evidence of planning; argued psychiatric disorder. Legal Importance: ➔ Premeditation does not necessarily bar diminished responsibility if a recognised condition substantially impaired D’s mental responsibility. Golden Nugget: ➔ Even planned killings can qualify if mental disorder explained conduct.
43
Constructive Manslaughter — Overview
➔ Unlawful and dangerous criminal act causing death. ➔ Must involve a positive criminal act (not omission) and be objectively dangerous. Golden Nugget: Dangerous unlawful act + causation of death = constructive manslaughter.
44
Gross Negligence Manslaughter — Overview
Back ➔ Breach of duty of care causing death in a grossly negligent way. ➔ Risk must relate to death, not merely serious injury. Golden Nugget: Extreme carelessness causing death is gross negligence manslaughter.
45
R v Lamb
Topic: ➔ Constructive Manslaughter — Core Offence Needed Brief Facts: ➔ D jokingly pointed revolver at friend; gun fired unexpectedly, killing him. Legal Importance: ➔ No base unlawful act if no assault; no manslaughter without core criminal offence. Golden Nugget: ➔ No crime, no manslaughter.
46
R v Grey
Topic: ➔ Constructive Manslaughter — Must Establish Base Offence Brief Facts: ➔ D physically restrained V in a way leading to death; base criminal act had to be clear. Legal Importance: ➔ Prosecution must establish the unlawful act clearly to ground manslaughter. Golden Nugget: ➔ Always identify the underlying criminal act.
47
R v Jennings
Topic: ➔ Constructive Manslaughter — Correct Offence Must Be Charged Brief Facts: ➔ Confusion over which offence underpinned D’s unlawful act. Legal Importance: ➔ Prosecution must properly identify and prove the specific criminal offence. Golden Nugget: ➔ Precision matters — wrong base offence = no liability.
48
R v Franklin
Topic: ➔ Constructive Manslaughter — Civil Wrong Not Enough Brief Facts: ➔ D threw a box into sea, hitting and killing V. Legal Importance: ➔ Only a criminal act (not a civil wrong) can ground unlawful act manslaughter. Golden Nugget: ➔ Civil wrong ≠ unlawful act manslaughter.
49
R v Andrews
Topic: ➔ Distinction Between Lawful Acts and Criminal Acts Brief Facts: ➔ D killed a pedestrian while driving carelessly. Legal Importance: ➔ Careless lawful acts are not enough — the base act must itself be criminal. Golden Nugget: ➔ Carelessness ≠ criminality for manslaughter.
50
R v Church
Topic: ➔ Constructive Manslaughter — Objective Dangerousness Test Brief Facts: ➔ D attacked V and believed her dead; later threw her into river where she drowned. Legal Importance: ➔ Unlawful act must be objectively dangerous — recognised risk of some harm. Golden Nugget: ➔ Would a reasonable person foresee some harm?
51
R v Dawson
topic: ➔ Constructive Manslaughter — Objective Danger Brief Facts: ➔ D used toy gun in robbery; V suffered fatal heart attack. Legal Importance: ➔ Objective standard: would a reasonable person have seen risk of harm? Golden Nugget: ➔ Fear-induced harm counts if objectively foreseeable.
52
R v Mitchell
Topic: ➔ Constructive Manslaughter — Third Party Harm Brief Facts: ➔ D punched a man who fell onto V, causing V's death. Legal Importance: ➔ Liability attaches even where harm caused to unintended victims. Golden Nugget: ➔ Transferring danger ≠ escaping liability.
53
R v Scarlett
Topic: ➔ Constructive Manslaughter — Causation Brief Facts: ➔ D ejected V from pub; V fell and died. Legal Importance: ➔ Must apply "but for" and legal causation principles. Golden Nugget: ➔ Causation must be clear and not too remote.
54
R v Lowe
Topic: ➔ Constructive Manslaughter — No Omission Brief Facts: ➔ D failed to seek help for sick child; child died. Legal Importance: ➔ Unlawful act manslaughter must be based on a positive act, not an omission. Golden Nugget: ➔ Omissions cannot ground constructive manslaughter.
55
R v Newbury and Jones
Topic: ➔ Constructive Manslaughter — Objective Dangerousness Brief Facts: ➔ Teenage boys threw paving stone onto a train, killing the guard. Legal Importance: ➔ Objective test: reasonable person would recognise risk of harm. Golden Nugget: ➔ Objective dangerousness, no need for D’s foresight.
56
R v Wacker
Topic: ➔ Gross Negligence Manslaughter — Duty of Care in Crime Brief Facts: ➔ D smuggled illegal immigrants; they suffocated. Legal Importance: ➔ Duty of care still owed even when victim is complicit in crime. Golden Nugget: ➔ Duty of care survives criminal partnerships. but not unlawful act because victims consented
57
R v Adomako
Topic: ➔ Gross Negligence Manslaughter — Medical Duty Brief Facts: ➔ Anaesthetist failed to notice disconnected breathing tube. Legal Importance: ➔ Set the modern test for gross negligence manslaughter. Golden Nugget: ➔ Gross breach of duty causing death = criminal.
58
R v Willoughby
Topic: ➔ Gross Negligence Manslaughter — Distinction from Civil Duty Brief Facts: ➔ D involved V in arson which led to V’s death. Legal Importance: ➔ Duty of care in criminal law assessed separately from civil negligence. Golden Nugget: ➔ Criminal duties aren't identical to civil law.
59
R v Miller
Topic: ➔ Gross Negligence — Duty from Creating Danger Brief Facts: ➔ D accidentally set fire but failed to take action. Legal Importance: ➔ Duty arises where D creates a dangerous situation. Golden Nugget: ➔ Cause danger = duty to fix it.
60
R v Singh
Topic: ➔ Gross Negligence Manslaughter — Risk of Death Brief Facts: ➔ D’s negligence in maintaining a gas fire led to death by carbon monoxide poisoning. Legal Importance: ➔ Risk must relate to death, not just injury. Golden Nugget: ➔ Risk must be serious and obvious: risk of death.
61
R v Kuddus
Topic: ➔ Gross Negligence — Risk Awareness Brief Facts: ➔ D served allergen-contaminated food causing V's death. Legal Importance: ➔ Distinction between existence of risk and D’s foresight; serious risk must be objectively obvious. Golden Nugget: ➔ Risk judged objectively, foresight not essential.
62
Gross Negligence Flow
1. Duty of care (wacker, willoughby, other duty of care) 2. breach (miller, evans) 3. causation 4. risk of death (objective r v kuddus, only deaht r v singh) 5. grossness (adomako)
63
Unlawful Act flow
1. unlawful act base (lamb, grey, jennings, franklin, andrews, mitchell, lowe) 2. objective danger (church, newbury, dawson and watson) 3. causation (kennedy, scarlett, grant)

Mens rea (malice aforethought): Intent to kill (oblique or direct) Intent to cause grievous bodily harm (GBH) (R v Vickers). 4. Transferred malice (if relevant) (R v Gnango, R v Mitchell) 5. No lawful defences – e.g., self-defence, loss of control, diminished responsibility.
66
participation
Under Jogee, D will be liable as a secondary party if he intentionally assisted or encouraged the principal’s crime, with foresight alone no longer sufficient to infer intent
