Questions from this subtopic

Each one with the model answer underneath.

1
Where do the rules on insanity come from?
Model answer
The rules on insanity come from M'Naghten's Case (1843). The judges answered questions put to them by the House of Lords after the acquittal of Daniel M'Naghten.
2
State the presumption from which the M'Naghten rules begin.
Model answer
Every person is presumed sane and to possess a sufficient degree of reason to be responsible. The defence must displace that presumption.
3
State the three elements of the M'Naghten rules.
Model answer
The defendant must have suffered a defect of reason arising from a disease of the mind. The defect must have caused the defendant not to know the nature and quality of the act, or not to know that the act was wrong.
4
What is a defect of reason?
Model answer
A defect of reason is a deprivation of the power to reason. A temporary failure to use powers of reasoning is not enough.
5
Which case decided that absent-mindedness is not a defect of reason?
Model answer
R v Clarke [1972] held that momentary confusion or absent-mindedness is not a defect of reason. A woman with diabetes and depression who took goods from a supermarket had not lost her powers of reasoning.
6
What does not knowing the nature and quality of the act mean?
Model answer
The phrase covers a defendant unaware of the physical nature of what is being done. A defendant who cuts a throat believing it to be a loaf of bread does not know the nature of the act.
