Legal Insanity (McNaughten rules) and Medications

Basically, criminal defendants found to be legally insane are not convicted of their offences because of mental defect or disability. Therefore, the criminal justice system employs various legal tests in determining if the defendant is legally insane or not. One of these legal tests used is the McNaughten rule. The McNaughten rule is also referred to as the right or wrong test. The McNaughten rule emphasizes on whether the criminal defendant was aware of the nature of the crime he/she was being involved with or comprehended the right from the wrong at the moment the crime was committed.

Therefore, the McNaughten rules provide that an individual is deemed legally insane is he /she was not capable of knowing the actions he /she was engaging in during the time a criminal offence is committed. This rule goes hand in hand with the culpability conception regarding criminal law. That is, a defendant is deemed not culpable of actions committed because of psychological infirmity. The second rule provides for the ability of a defendant of determining whether his/her actions were not right. In this case, despite the fact that the defendant was aware of what he/she was engaging in, the defendant is considered insane if he/she is not able recognize wrongfulness as far as the act that is carried out is concerned.

Diminished Capacity

Diminished capacity is a doctrine that provides an opportunity to a defendant of avoiding liability to a crime by showing that his /her mental capacity was much diminished to a point that he/she was not in a position to have the intent of committing the crime he/she is being charged with. Therefore, the defendant should prove that he/she lacked the intent that is required for a crime to be committed because of mental impairment. In this case, the lack of sanity is not invoked with a view of disapproving intent. Rather, it is employed to prove that the defendant did not have the basic capacity that could have enabled him/her to shun away from engaging in a behavior that can be termed as morally comprehensive simply because he/she did not understand the wrongfulness of the act he was doing or he/she was not able to control his/her actions. Thus, if the evidence that is provided fails to prove that the defendant was legally insane, evidence can be provided for proving that a defendant had diminished capacity.
