R v Stone and Dobinson

Facts

Stone and Dobinson shared a home. Stone's sister, Fanny, came to live with them. Fanny was anorexic and largely bedbound, incapable of looking after herself. The defendants attempted to care for her but did not seek medical help or ensure she received sufficient nourishment. Fanny died from malnutrition and related complications. Both defendants were convicted of gross negligence manslaughter.

History

The defendants were convicted at the Crown Court. They appealed to the Court of Appeal, arguing that no legal duty to act existed and that their omissions could not form the actus reus of a crime.

Issue

Whether a person who voluntarily assumes care for a vulnerable adult owes a legal duty to that person; whether a breach of that duty by omission can satisfy the actus reus of manslaughter.

Held

Appeal dismissed; convictions upheld.

Ratio

• A legal duty to act arises when a person voluntarily assumes responsibility for another who is unable to care for themselves. A grossly negligent failure to discharge that duty can constitute the actus reus of manslaughter.

Key reasoning

• The court identified voluntary assumption of responsibility as a recognised category of duty in omissions liability.
• The defendants' knowledge of the deceased's vulnerability and their decision to care for her themselves created the duty.
• The standard of care required was that of a reasonable person in the defendants' position; the breach had to be gross to support a manslaughter conviction.

Where it fits in the module

This case is a cornerstone of Topic 1 (Basic Principles) for the actus reus of omissions. It sits alongside Miller (duty from creating a dangerous situation) and Evans (duty from creating a dangerous situation) as one of the principal categories of duty. It contrasts with the general rule that there is no duty to rescue, illustrating the exceptional circumstances that generate liability. It also connects to the debate on the moral limits of criminalising omissions and the standard of gross negligence in manslaughter.

Criticisms

• The concept of voluntary assumption is vague and may impose liability on informal carers who lack resources or expertise.
• The gross negligence standard for manslaughter by omission is difficult to distinguish from civil negligence.
• The decision may discourage people from helping vulnerable relatives for fear of criminal liability.
• The line between a moral obligation and a legal duty remains contested.
