Gross Negligence Manslaughter
What is Gross Negligence Manslaughter?
Gross negligence manslaughter is a form of unlawful killing where the defendant’s grossly negligent conduct causes the death of another person. It differs from murder as it lacks intent to kill or cause grievous harm but involves a culpable disregard for life or safety.
Legal Framework and Elements
In jurisdictions like the UK, gross negligence manslaughter is recognized under common law and has been elaborated through case law. The main elements are:
Existence of a Duty of Care: The accused owed a duty to the deceased.
Breach of that Duty: Conduct fell below the expected standard of care.
Negligence was Gross: The negligence was so serious as to justify criminal liability.
Causation: The breach caused the death.
Risk of Death: The negligence created a foreseeable risk of death.
Key Case Laws on Gross Negligence Manslaughter
1. R v. Adomako (1995) (House of Lords, UK)
Facts:
An anesthetist failed to notice that a patient's oxygen tube had become disconnected during surgery, resulting in the patient’s death.
Judgment:
The House of Lords formulated the modern test for gross negligence manslaughter.
Held that the breach of duty must be “gross” to the extent that it justifies criminal punishment.
The jury must consider if the negligence was so bad as to be criminal.
Conviction upheld.
Significance:
This is the leading authority setting out the test for gross negligence manslaughter in English law.
2. R v. Singh (1999) (Court of Appeal, UK)
Facts:
The defendant, a landlord, failed to maintain proper gas appliances, resulting in a fatal gas leak.
Judgment:
The court held Singh owed a duty of care as a landlord.
His failure to repair the appliances was grossly negligent.
The breach caused the tenant’s death, satisfying the test for gross negligence manslaughter.
Conviction upheld.
Significance:
This case expanded the duty of care concept to non-medical, residential contexts.
3. R v. Bateman (1925) (Court of Criminal Appeal, UK)
Facts:
A doctor delivered a woman negligently, failing to provide adequate care, resulting in her death.
Judgment:
The court held that negligence must be “such disregard for the life and safety of others as to amount to a crime against the state.”
The case defined the threshold for gross negligence prior to Adomako.
Conviction was quashed for lack of sufficient evidence of gross negligence.
Significance:
Bateman laid foundational principles distinguishing gross negligence manslaughter from mere civil negligence.
4. R v. Misra and Srivastava (2004) (Court of Appeal, UK)
Facts:
Two doctors were charged after a patient died from post-operative infections that could have been prevented.
Judgment:
The court reaffirmed the Adomako test.
Held that gross negligence requires a risk of death, not just injury or harm.
The defendants’ conduct fell far below acceptable standards.
Conviction upheld.
Significance:
Confirmed the importance of foreseeable risk of death in gross negligence manslaughter.
5. R v. Evans (2009) (House of Lords, UK)
Facts:
The defendant supplied heroin to her half-sister who overdosed and died; she failed to seek medical help.
Judgment:
The court held the defendant owed a duty of care because she created or contributed to the dangerous situation.
Failure to act was grossly negligent.
The case linked omission (failure to act) with gross negligence manslaughter.
Significance:
Extended gross negligence manslaughter liability to cases of omission, where there is a duty to act.
6. R v. Wacker (2003) (Court of Appeal, UK)
Facts:
The defendant was involved in illegal immigrant trafficking; some immigrants died due to suffocation.
Judgment:
The court held Wacker owed a duty of care despite the illegal activity.
Gross negligence caused death.
Conviction was upheld, emphasizing that illegal context does not exclude duty.
Significance:
Clarified that duty of care exists even in unlawful enterprises for gross negligence manslaughter.
