R v Watt

The case of R v Watt involved the defendant, Watt, who was charged with armed robbery and larceny. The dispute centred on the defendant's actions during a bank robbery where he used an offensive weapon, and the question of his mental state at the time of the offence. The matter was heard in the Supreme Court of Victoria.

The primary legal issues the court had to address were whether Watt was criminally responsible for the offences committed and, if so, to what extent his mental health affected his culpability. The court needed to determine whether Watt was suffering from a mental illness at the time of the crime and if such illness could be deemed to have substantially impaired his ability to understand the nature and quality of his act or to know that what he was doing was wrong.

The court found that Watt was indeed suffering from a mental illness at the time of the offence, which substantially impaired his ability to appreciate the wrongfulness of his conduct. The evidence presented showed that his mental condition significantly affected his decision-making capacity. The court accepted the defence of diminished responsibility but noted that it did not absolve Watt of all responsibility. The special verdict found Watt guilty of the lesser charge of larceny, as opposed to armed robbery, due to the mitigating factor of his mental state. The court reserved the matter for further orders on 30 October 2025, when it will hear submissions on the appropriate sentencing and other orders to be made.
