McNaghten Rule

The McNaghten Rule is a legal standard used to determine if someone can be considered legally insane at the time they committed a crime. It states that a person is not criminally responsible if, due to a mental illness, they did not understand the nature of their actions or did not know that what they were doing was wrong. In essence, it focuses on the person's mental state and awareness during the crime, helping courts decide whether they can be held accountable or require different treatment.
