Regina vs. M'Naghten, also known as the M'Naghten Rule, is widely considered the beginning of the modern insanity defence. This case established the test for criminal responsibility, stating that a defendant is not guilty by reason of insanity if at the time of the crime they did not know the nature and quality of the act they were committing or did not know it was wrong. This ruling had a significant influence on the development of the insanity defence in other common law jurisdictions, including the United States.
