GENERAL PART
2. A CRIME AND CRIMINAL RESPONSIBILITY
2.1. General provisions on crime and criminal responsibility
Real mistake
Article 16
(1) The offender is not criminally responsible, when at the time the crime was committed, he had no knowledge of some of its characteristics, determined by law; or if he wrongly considered that there are circumstances according to which, if they had existed, this would have been permissible.
(2) If the offender was under mistaken notion out of negligence, he is criminally responsible for the crime committed out of negligence, if the law determines a criminal responsibility for such an act.
Mistake of fact - national proceedings
