No responsibility attaches to whoever, at the time of the act or omission, and due to mental illness, incomplete or retarded mental development, or to a severe disturbance of conscience, lacked the capacity to understand the unlawfulness of his act or to conduct himself in accordance with said understanding.
The court will order a therapeutic security measure for the person concerned, except in the case of a severe disturbance of conscience, of unknown pathological origin, where no measures will be applied.
