Dunnage v Kathleen Bernadette Randall UK Insurance Ltd

Dunnage v Kathleen Bernadette Randall UK Insurance Ltd

A person suffering from mental illness is liable in negligence for injury caused by his actions unless his condition entirely eliminates responsibility such that he does not act at all; mere impairment, delusion, or irrationality does not excuse liability. The standard of care remains objective. Vince's actions, though directed by his deranged mind, were still his actions and breached the duty of care. The injury was accidental and not excluded under the policy.

Legal Issues

  1. 1 Whether a person suffering from mental illness to the extent that his actions are entirely directed by his deluded and deranged mind is liable in negligence for injury caused to another
  2. 2 Whether the standard of care in negligence is objective and applies to mentally ill defendants

Ratio Decidendi

A person suffering from mental illness is liable in negligence for injury caused by his actions unless his condition entirely eliminates responsibility such that he does not act at all; mere impairment, delusion, or irrationality does not excuse liability. The standard of care remains objective. Vince's actions, though directed by his deranged mind, were still his actions and breached the duty of care. The injury was accidental and not excluded under the policy.
