Defect of reason

Disease of the mind

  • A legal definition, not a medical definition.
  • Defined in R v Sullivan.
    • D kicked a man when he was having an epileptic fit. Epilepsy is an internal factor, and thus, a disease of the mind.
  • A disease of the mind is a disease affecting the mental faculties of reason, memory and understanding, and cannot arise from an external cause.
