Article 25 Mistake of fact
1. A person is not criminally liable if, at the time of committing a criminal offense, he or she is unaware of a characteristic of that act or he or she mistakenly believed that circumstances existed which, had they in fact existed, would have rendered the act permissible.
2. If a person’s mistake is due to negligence, he or she is criminally liable for a criminal offense which has been negligently committed if the law specifically provides for criminal liability for the negligent commission of that offense.
