R v Sandhu

In the matter of R v Sandhu, the defendant was convicted of attempted murder following an incident in which he stabbed his wife multiple times in the neck with a knife, resulting in significant physical and psychological harm to the victim. The case was heard in the Supreme Court of the relevant jurisdiction. The defendant had a history of domestic violence and schizophrenia, which influenced his actions and the plea of guilty he entered.

The court was required to balance the severity of the offence against the defendant's low moral culpability, which was significantly influenced by his mental state. The defendant's delusional thoughts, precipitated by schizophrenia, led him to believe that his wife was attempting to poison him. This mental condition reduced the general deterrence, specific deterrence, curial denunciation, and just punishment considerations. Despite the strong defence of mental impairment, the defendant entered a guilty plea and showed some remorse. The court also had to consider the impact of the defendant's illness on the hardship of imprisonment and his prospects for rehabilitation.

The court found the defendant’s plea of guilty, his low moral culpability, and the impact of his mental illness to be significant mitigating factors. The sentence was reduced to seven years' imprisonment with a non-parole period of four years, reflecting these mitigating factors. Without the plea of guilty, the sentence would have been ten years with a non-parole period of seven years. The court also noted that, but for the defendant's mental illness and plea of guilty, the sentence would likely have been in the order of 12 to 14 years' imprisonment.
