On his trial for murder the defendant produced unchallenged expert evidence that at the time of the offence, his mental responsibility for the killing was substantially impaired by his mental illness. He said that in these circumstances the charge of murder should have been withdrawing leaving only manslaughter available to the jury.
Held: The medical evidence was not the sole determinant. There was other evidence that the defendant had acted intentionally, and the jury was correctly allowed to consider it. The appeal failed.
