R v Clough

In the case, the accused was charged with the murder of a woman, for which he pleaded not guilty. The case was tried by a Judge sitting without a jury, and the central issue was whether the accused was sound of mind at the time of the offence, which would determine his criminal responsibility. The court had to decide if the accused's voluntary consumption of drugs constituted intoxication, and whether this affected his capacity to know that he ought not to commit the act. The defence also argued that the accused suffered from an abnormality of mind, potentially amounting to diminished responsibility.

The court examined the nature of the accused's drug use and the impact it had on his mental state at the time of the offence. It was established that the accused had a history of drug abuse and had voluntarily consumed a significant amount of drugs prior to the incident. The court considered whether this constituted intoxication and whether it could be classified as an abnormality of mind. The judge found that while the accused's consumption of drugs impaired his mental state, it did not rise to the level of an abnormality of mind. The court held that the accused was capable of knowing that his actions were wrong, and therefore, he was criminally responsible for his actions.

The court concluded that the accused's voluntary intoxication did not negate his criminal responsibility for the murder. The intoxication did not reach the level of an abnormality of mind or diminish his capacity to know the wrongfulness of his actions. The court rejected the defence's argument of diminished responsibility, finding that the accused's actions were not significantly impaired by any mental condition. The accused was found guilty of murder. The court ordered the accused to be detained at Her Majesty's pleasure.
