Further, exceptions arise where an involuntary act results into a prohibited conduct that occasions an injury or harm. A person that acts or omits to act in a way that is not of free will or is involuntary, acts or omits to act due to no fault of his and cannot be held criminally liable as such a person is said to be in a state of automatism. In criminal defence, automatism is not oftenly used. It is one of the rare mental condition defences that relate to the mental state of the accused. Automatism can be seen variously as lack of voluntariness, lack of culpability (unconsciousness). Automatism means therefore that the accused was not aware of his or her actions when making the particular movements that constituted the illegal act.
