The McNaghten rules, also known as the right-and-wrong test, establish that individuals cannot be held criminally responsible for their actions if they had a mental disability that prevented them from understanding the nature and consequences of their actions, or determining whether their actions were right or wrong. This test is applied in federal courts and most states. If a person lacked awareness of their actions or their wrongfulness due to a mental defect, they cannot be convicted of a crime. Similarly, if a person acted based on a delusion caused by insanity, their legal responsibility remains the same as if the circumstances were as they perceived them.
The legal doctrine known as the right-and-wrong test is used in criminal law to establish a person’s criminal responsibility for their actions. Also referred to as the McNaghten rules, this doctrine was established in 1843 in England. According to the McNaghten rules, a person is not criminally responsible if a mental disability prevented them from understanding the nature and quality of their actions, or from knowing whether their actions were right or wrong. This means that if a person did not comprehend their actions or did not realise they were wrong, they cannot be held accountable for a crime. For example, if a person with a mental illness believed they were killing a monster rather than a human being, they may not be held responsible for murder under the right-and-wrong test. This test is utilised in many federal courts and states in the United States, and is only applicable in cases involving a “defect of reason, from disease of the mind,” which includes congenital defects or traumatic injuries. If a defendant did not understand their actions due to this defect, they are not guilty of a crime. Even if they were aware of their actions, they are not guilty if they did not know it was wrong because of the defect. In summary, the right-and-wrong test is used to determine whether a person with a mental disability can be held responsible for a crime based on their understanding of their actions.
