R v Sands

In the matter of R v Sands, the accused faced a charge of murder. The case involved a complex interplay of mental health and cognitive impairments, leading to a special verdict under the Mental Health and Cognitive Impairment Forensic Provisions Act 2020 (NSW). The defendant, who suffered from Major Depressive Disorder with psychotic symptoms and was also afflicted with Posterior Cortical Atrophy and Lewy Body Dementia, was assessed by medical experts. These experts unanimously agreed that the defendant's conditions met the criteria for both mental health and cognitive impairments as defined by the Act. The primary issue before the court was whether the defendant could be found not criminally responsible due to these impairments, despite the prosecution accepting that the impairments existed.

The court had to determine whether the defendant's mental health and cognitive impairments were such that they negated her criminal responsibility for the act. The legal issue revolved around the interpretation and application of sections 28 and 31 of the Act, which pertain to the conditions for a special verdict of act proven but not criminally responsible. The prosecution and the defence agreed that the defendant suffered from significant impairments, but the defence argued that these impairments rendered her incapable of understanding the nature and quality of her act or knowing that it was wrong. The court had to assess the evidence and the expert opinions to ascertain whether these impairments indeed absolved the defendant of criminal responsibility.

The court, after carefully considering the evidence and expert opinions, found that the defendant's impairments were severe and had a profound impact on her mental faculties. The unanimous medical opinion confirmed that the defendant did not know the nature and quality of her act nor did she know that it was wrong due to her conditions. Therefore, the court concluded that the defendant was not criminally responsible for the act. The judge, acting alone, entered a special verdict of act proven but not criminally responsible. This verdict acknowledges the defendant's involvement in the act but exempts her from criminal liability due to her mental and cognitive impairments.
