Whether the criminal proceedings against N.________ should be discontinued by a non-lieu because of total irresponsibility
Yes. The court found that N.________ suffered from a severe mental disorder and had no capacity to appreciate the unlawfulness of his acts, so he was not punishable.
The psychiatric expertise established total irresponsibility under Art. 19(1) CP; because the irresponsibility could not be avoided, prosecution had to end with a non-lieu under the CPP provisions cited by the court.
