Answer: whether an issue is right vs. wrong.
Explanation:
Right and Wrong Test, also known as McNaghten rules is a test for criminal insanity. It is any variant of the 1840s jury instruction in a criminal case when there is a defence of insanity.
The rule was formulated as a reaction to the acquittal in 1843 of Daniel M'Naghten on the charge of murdering Edward Drummond.
This criminal law doctrine says that a person is not criminally responsible for an act when a mental disability prevented the person from knowing either the nature or quality of the act or whether the act was right or wrong.
