R v EY (No 2)

In the case of R v EY (No 2), the defendant was charged with manslaughter after she gave birth to an infant in her family home and left the infant outside on a neighbour’s premises, where it was exposed to the elements and subsequently died. The defendant sought an application under section 269C of the relevant legislation, arguing that she was mentally incompetent to commit the offence. The central issues before the court were whether the defendant knew the nature and quality of her conduct, and whether she understood that her conduct was wrongful. The court was required to determine whether the defendant’s intellectual disability impaired her capacity to know the physical nature of her actions, their consequences, and the wrongfulness of her conduct.

The court considered the evidence of two expert witnesses, Dr Raeside and Dr Tomasic. Dr Raeside initially did not support a mental incompetence defence but later changed his opinion, attributing the change to the nature of the charge and the defendant's intellectual disability. Dr Tomasic, however, held the view that the defendant understood the need for the baby to be kept warm and recognised the cold outside, which led to her concerns about her own health. Dr Tomasic concluded that the defendant had an adequate understanding of the nature and quality of her actions. The court accepted Dr Tomasic's evidence and found that the defendant understood that a newborn required care and attention. The court was satisfied that the defendant knew the nature and quality of her conduct.

The court found that the defendant understood the need to keep the baby warm and recognised the cold outside, indicating an understanding of the physical nature of her actions. The court concluded that the defendant knew the nature and quality of her conduct and was thus mentally competent to commit the offence. The application for a finding of mental incompetence was therefore refused.

As a result of the findings, the court ruled that the defendant was mentally competent to commit the offence of manslaughter. The court's decision underscored the importance of understanding both the physical nature of the defendant's actions and their consequences, as well as the wrongfulness of her conduct, in determining her mental competency. The defendant's intellectual disability, while acknowledged, did not sufficiently impair her understanding to negate her criminal responsibility.
