Definitions of legal insanity differ from state to state. There are also several standards for measuring insanity. The first is often called the M'Naghten Rule, which comes from an 1843 case where a man (Daniel M'Naghten) was found not guilty of an attempted assassination of the Prime Minister of Britain because he was insane. The public outrage following M'Naghten's acquittal lead to the creation of the M'Naghten Rule. According to the M'Naghten Rule, a defendant could not be held responsible for his actions if, as a result of his mental disease or defect, he did not know that his act would be wrong or did not understand the nature and quality of his actions.
The M'Naghten Rule was used until the 1950's when the Durham test became the new standard (Durham v. United States). In Durham, the court ruled that a person was legally insane if he "would not have committed the criminal act but for the existence of a mental disease or defect."
By the 1970's, most courts had adopted the MPC (Modern Penal Code) standard, which was a compromise between M'Naghten and Durham. Today, most states have adopted their own standards based on the MPC.

Is insanity a justification defense?
In the US, temporary insanity or permanent insanity is a defense when a person commits a crime. The reasoning is logical. Persons mentally ill very often have no idea what they are doing if they strike someone on the street for no cause. Clearly this person is too mentally impaired to obey laws and medical help rather than jail is required. Also, there is a defense called temporary insanity. In this situation, if a person has anger problems and reacts to a situation that brings them into a rage, the offense may be excused or if convicted, the person may be charged with a lesser crime. Here' s an example. If a husband comes home to find his wife in bed with another man, the rage might cause the intruding man to be seriously assaulted by the husband who can be said to be temporarily insane.
